Warning: this story is for readers 18+.

I look up at Maribel, our futanari centaur who also happens to be our most reliable driver here at the routing center, with a bashful expression, hoping against all reason she can find it in her big, horsey heart to forgive me.

I was up all night studying for my delivery driver certification. When I woke up, I found I was late to my shift at work. My supervisor’s disappointment in my lateness had left me anxious, and my anxiety had led me to get the mail sorting process wrong, delaying the shipments of three time-sensitive parcels.

And that means deliveries are gonna be late, and the routing center might miss its quota, and that might have ramifications on our bonuses.

Yep, I might’ve fucked up.

My supervisor suggested I tell Maribel that I’ve messed up her day off and that I was the cause of her inconvenience.

“I’m so sorry I got the parcels wrong, Maribel. I feel terrible. It’s not fair you’re coming in on your day off and it’s all my fault. Is there anything I can do to make it up to you?”

Maribel smiles down at me from the top of her high horse body. Her blonde, braided ponytail flows down over the side of her enormous chest. She’s easily eight or nine feet tall from the top of her equine head all the way down to her big hooves. I can’t tell you how much I appreciate how she doesn’t wear her work shoes at the center. Her clopping hooves make a beautiful percussion, and that’s without mentioning the hypnotic way her bare ass tenses when she walks. Suffice it to say, Maribel has been the subject of my fantasies for as long as I’ve worked with her.

I have a type: big, powerful women with even bigger cocks that they’re eager to thrust down my tight throat and into my tighter ass. Maribel fits that bill on all counts. She has a pair of G-cup breasts, massive biceps, powerful legs, and she has that beautiful centaur cock that is long and hard and thick and has a gorgeous flared tip... just the way I like them.

Of course, I’m not supposed to look or think about her cock — you know, something-something professional standards — but you can’t work on a routing floor that sees so many dildos, vibrators and buttplugs shipping in and out all day, every day, without letting your mind wander, and fantasizing that one of those monster dildos belongs to a hung futa like Maribel and that it was meant to go deep inside me...

I like to imagine I’d be able to take her to the base and make her feel amazing. As a bovine girl, I’ve got a bit more room than most, but she seems more than even I could handle.

“You’re sorry, eh?” Maribel says as she leans over her human torso to look at me more evenly. “Well, I was kinda hoping for a quiet morning, darlin’.” She lifts up her horse leg, as if stretching out the long limb from hip to hoof. “A ride through the countryside, the wind through my mane... That kinda thing.” Her brown eyes crinkle into a grin.

I nod in complete agreement. “Yeah, that does sound nice. It’s a gorgeous day, after all.”

Maribel leans her upper body back up to her full height. She looks at the three parcels on the table beside me. She reaches for a strap attached to the front of her equine harness and uses it to tie her golden hair back into a high ponytail.

“But... it would feel good to help you out in your time of need.”

I take a deep breath, letting the relief wash over me. I smile up at Maribel and say, “Thank you! You’re the best.”

She taps the top of the table beside her with a knuckle. “These parcels are going way outside of town, so my horse legs are gonna come in handy for speedy delivery. But the owners will not be pleased that we’re so late.” She pauses, giving me a stern look. “I’ll do this for you if you agree to make it worth my time. I’ve got me a little game I like to play that’ll guarantee that everyone involved is happy with the end result, if you catch my drift.”

My heart speeds up and my nipples go instantly hard against the lace fabric of my bra. “Y-yes, ma’am,” I say. I’m not quite sure I understand what she’s proposing, but the way she said that made me want her so fucking bad that I’d agree to pretty much anything. I’ll play whatever game she wants and let her take any prize she wants. Hell, she can have me right here on the routing floor if she asks for it. I’ll let her ride me to her heart’s content.

Maribel reaches a hand into her courier’s pouch, pulling out a set of long, black straps. “Put these on,” she says, offering me the straps.

I look at them, recognizing them as the straps of an equine harness. There are no bits or reins, just the harness. I take them from her and hold them up against my body.

“Uh, what is this? A costume? How’s it work?”

Maribel snorts and stamps a front hoof on the tile flooring. “I’m about to give you a ride, so it’s only fair you get dressed for the part. Now, you wanna get your mail delivered on time or don’t you?”

I nod.

“Well, I’m gonna need you to strip and get into that harness if I’m gonna agree to take these parcels off your hands.”

My pussy tingles as the pieces click into place. Maribel wants me to get into a harness so she can strap me onto her undercarriage. My excitement grows exponentially.

I quickly pull off my shirt and my bra, my heavy tits falling free and my nipples growing stiff in the cool, circulating air of the routing floor. My skin tingles with the thrill of exposure as I bend over to shuck off my pants and underwear, leaving me fully naked.

“L-like this? Are they on right?” I hold up the tangle of straps bashfully. The chest strap has a loop at each end that’s meant to go around each upper arm and two additional straps attached to it meant to circle each breast. The lower strap is shorter and has loops meant for my thighs. The center has a large O-ring attached to it. I’m not entirely sure what I’m meant to do with all that.

Maribel steps in close, her soft hand taking the strap from me as her big horse body comes to rest just inches away. My pulse races as she leans over and slides one loop over my left arm, her hand grazing my naked shoulder.

“Relax, girl, I know what I’m doing.” Her voice is sultry and calm. She’s done this before, I realize. With who else, I have no idea.

She moves around me, tightening the chest harness into place. It pulls my breasts into two distinct mounds, squeezed by the straps and leaving the flesh pushed out and vulnerable. My nipples pucker up into hard buds. Maribel then grabs the lower harness and attaches it to my thighs and to my chest harness at the small of my back, which leaves the O-ring dangling between my legs in the most suggestive of ways.

The straps leave my stomach free, the soft of my tummy hanging between them, and my asshole and pussy are on full display, unencumbered by fabric.

“Gosh darn, honey, you’re already wet,” Maribel says, her hot breath hitting the side of my neck. A strong shiver runs through me. “I wonder just how wet I can get you...”

My face goes beet red, both from the attention of being so fully on display and at being caught already aroused. I’ve only ever played my kinky games at home where nobody could see or know. The thrill of being nude, harnessed and on display like this in the middle of my workplace is making me wetter by the minute, especially now that I’m basically being offered up to Maribel’s whims. My head spins.

Maribel takes my elbow and pulls me towards her front. Her strong, brown hands grasp my waist and then my thighs, and I can do nothing as she lifts my naked, harnessed body up off the ground. A gasp escapes me as I dangle in her hands for a moment, but she quickly has me situated so my suddenly bound arms are over my head. She straps me in so my head is between her front legs and my arms are hoisted above me, connected to a harness around her humanoid waist. My thigh and ankle straps are easily clipped into place, attaching to her underbelly straps. In a jiffy, my body is now fully suspended beneath her, my head, arms, and chest facing forward between her legs. My belly dangles while my legs and ankles are well-secured. I am quite literally caught up under Maribel, unable to move.

I’m fully at her mercy.

It takes me a moment to realize that my bare ass and pussy are no more than a foot away from Maribel’s huge sheath and fat dangling horse balls. My breathing goes shallow as I imagine what her cock might feel like sliding against my slick labia, how her hefty balls would sound clapping against my flesh.

“Hey! This isn’t safe work attire, Maribel!” my supervisor, Merin, calls out as Maribel snaps on her horseshoes.

I cringe, not having realized Merin was back on the floor, and my head swims. I’m so fucked.

Maribel clicks her tongue. “Hey now, Mer. We’re gonna be on the road for a while, darlin’, and I need my fixings. Can’t let your superstar express driver go out on the town without her favorite harness, can ya?” Maribel chuckles. “Ever hear about talent management?”

I hear Merin chuckle as well, and I’m thoroughly confused as to what is transpiring.

“Fine, fine,” Merin says. “But you owe me for making me miss the show.” Then I hear Merin’s footsteps heading away from us.

I peek under me as Maribel grabs the parcels. I see Merin round the corner of the aisle, her curvy ass highlighted by her khaki slacks and the red courier polo shirt straining across her thick tits. She pauses long enough to wiggle her fingers at Maribel and me in a little goodbye.

Is Merin into this shit, too?

“Hold tight, darlin’,” Maribel says to me as she walks toward the exit door, ensuring the three parcels are secured to her back.

I feel every step in her gait. The motion bounces my naked tits against my chest and has my cock-hungry cunt throbbing. My arms have gone numb from their extended position, but the pain is nothing in the face of what I suspect Maribel’s ‘game’ is.

We’re barely through the employee parking lot before I feel a firm, wet and hot something press up between my ass cheeks.

Maribel stops in her tracks. The tip of her member grinds up the length of my ass. I gasp at the heat and feel the wetness of her pre trailing down onto the backs of my thighs and into my already drenched cunt. A pulse of pleasure washes over me.

“Oh my god,” I mewl as her fat equine tip passes my tailbone and prods at the sensitive bud of my asshole. I have never been fucked by a cock this large in my life, let alone in an open parking lot with any random passerby able to look up and see me. A fresh wave of arousal flushes through my body.

Maribel gives my hole a few more prods before she sets off down the lane. “We got a bit of a ways to ride, little filly,” she says with a laugh, “I’m so fuckin’ horny already.” Her cockhead teases me like a blunted-headed tentacle.

The cool morning air laps at my wet folds, and my clit is aching for friction. I’m so turned on by all of this.

Maribel clicks her tongue again as she turns down a street. Her cockhead once again finds my hole, but instead of pushing inside, it rubs against my entrance and then slips away up my slit.

“I’m going to tease us both for this ride,” she says. “You just lie back, enjoy the view, and keep that cunt nice and wet for when I’m ready to make proper use of it. Okay, darlin’?”

I bite my lip to stop a wanton moan as she hits just the right spot with her wide dick, grinding my clit so perfectly as to light up my whole cunt with the promise of an orgasm. My tits swing and sway from the rhythm of her steps, and I want to touch my nipples and my clit so bad it hurts. But with my arms bound up, all I can do is hang on and let Maribel have her way with my body.

We pass pedestrians, other cars; I can’t be sure who can see what’s going on between my thighs. Maribel doesn’t even miss a beat as we come across stoplights or other vehicles. Her huge cock grinds against my flesh as she moves. The sheer filthiness of it all is too much.

“Maribel...” I gasp out, barely coherent through the rising pleasure. Each step sends a pleasurable reverb through my cunt.

“Yeah, darlin’?” Her tone is casual. “What’s the matter? Don’t tell me this is too much for you.”

“I’m... I can’t... I need more...”

She laughs. “Oh, honey. I knew you had an itch, but I didn’t know you needed scratching this bad!” She thrusts forward, forcing herself between my wet folds and bumping up against my clit, the spongy head of it sliding past. “There. Is that better?”

I can only whine in pleasure.

“Okay,” Maribel says, adjusting to a quicker pace so her huge horse cock slips along my labia in quick strokes. The slick noises are lewd in the early morning, but the extra friction feels absolutely incredible. “You hold on tight, little filly, I’m gonna get you off but good before I give you the ride you’ve been asking for.”

I mewl at her words as a tremor rocks through me, her fat member rubbing me to my first orgasm of the day. “Ohhh,” I groan, unable to be quiet about it. I try to close my legs to add more pressure, but her strong body has my legs pinned wide. As she gallops down the street, a group of guys whistle at me from an open convertible, thumbs up at the view.

By the time we reach the long road that leads out to the suburbs, I’m shaking with aftershocks. My pussy is drenched and throbbing, and my asshole is clenching down on nothing as I ride out wave after wave of my orgasm.

Maribel takes a moment at a red light to get me off one more time with a few calculated thrusts against my swollen clit before turning up a side street and heading for the first delivery address. “Well damn, I can’t wait any longer,” she says between gritted teeth. “I know that tight ass of yours has been winking at me for ten miles.”

She pulls down the long driveway and stops at the gate to hit the intercom. “Special delivery for Mr. Harding!” she calls into the speaker.

In a minute the gate buzzes open and Maribel takes off at a canter towards the main house. When she’s just a few feet from the porch, a tall gentleman with a barrel chest, salt-and-pepper hair and a thick black mustache steps outside to greet us. He looks up at Maribel, then down at me, drenched in sweat with my breasts swinging free.

“Mr. Harding, I presume?” Maribel says with a grin. “I got your package and I’ve got an apology for being late. I’d be ever so grateful if you’d accept it as is.”

The gentleman eyes Maribel with a cocked brow, then glances back down at me. “Well, this is quite the surprise! I accept! Though, if I’d have known a centaur courier could be persuaded to wear such an... innovative uniform, I’d have requested it long ago.” He takes the package, gives my breasts a firm grope, and we’re off.

“Your little show was too much for me, I’m afraid,” Maribel pants, her huge chest heaving. “I just gotta fuck your little hole until I come, ya hear?”

My mouth waters, and I try to buck my hips, but I’m strapped in too tightly.

Her huge cock prods at my slick ass, pushing against my clenched pucker. The stretch is painful at first and my hole refuses to open, but Maribel pushes and prods at me until the thick flared head of her horse cock pops through the tight ring of my muscles.

“Maribel...! Wait... you’re too big!” The burn is intense as she thrusts forward, stretching me wide.

“Hang on, filly,” she pants, pausing once she’s popped in, letting me adjust. “I don’t hear no real complaints. Now, breathe. Nice and deep...”

“Aaaaaaaah, god! It’s so big!” I keen, tears springing to my eyes. She’s only a few inches in, and I already feel stretched beyond belief. And then she starts to push again.

“Unnngg,” I moan as another few inches sink in. Her huge dick rubs along every sensitive inch of my guts, rearranging my insides so her massive dick will fit. My ass is throbbing, my stomach aches, my legs tremble.

“That’s the ticket,” Maribel grunts, and then she starts to pull out. “Oh yeah, that’s a good fuckin’ ass, little filly!”

“Wait!” My voice is strained as she tugs back on my rim, pulling me with her before pushing back in. She repeats it a few times, letting her horse cock feel out my ass before sinking in deep again.

“I’m gonna take my time, filly. Gotta enjoy the ride, right? Life’s too short for all groaning and no moaning.” Maribel slows to a steady gait, making the pace of her thrusts into my ass a constant and maddening torture.

I moan and keen as her girth stretches my fat ass, feeling each flaring of her tip as it pops out of me only to squeeze right back inside. Her strokes start out slow and short, but before long, Maribel’s thrusts get deeper and longer, until her huge cock is bottoming out inside me and hitting what feels like the back of my fucking ribs. The flared head rubs over every sweet spot inside my guts, setting them alight and causing my ass to clench down on her over and over, only intensifying the sensation.

The ache in my stomach grows to a dull, pleasurable throb as Maribel pounds into my ass. I can feel my belly bulging from the inside as her cock grinds along my inner walls, rearranging my guts until she’s found the perfect position to hammer that huge head of hers into me. I’ve never been filled so thoroughly.

“You feel amazing, filly,” Maribel pants as her speed picks up. “Gotta give you the ride of a lifetime as thanks, right? Oooh, yeah, just like that. Milk me, babe... Keep that ass clenched down tight!”

I want to tell her how good she feels, but all I can do is take her fucking and drool a puddle underneath me. My mind is full of the wonderful pleasure of her huge, thick shaft sawing in and out of my ass, the weight of her big heavy balls slapping against my ass and thighs as she moves, the obscene way my tits are swinging in rhythm with her powerful thrusts.

If I could touch my stomach, I’d be able to feel her pistoning inside me, turning my insides into a sea of pleasure. My poor tummy bulges and my intestines shift with every movement she makes. She’s in so deep, but I want more.

“Fuck me, fuck me, fuck me!” I scream as she speeds up and I’m finally able to find my voice again. “Please don’t stop, Maribel! Don’t stop!”

And she doesn’t. I hear her whinny as her horse half bucks and her thrusts become frenzied, pushing her enormous length in and out of me, giving my ass a pummeling that makes my whole body shake. With each deep thrust she grinds her hips down against me, rubbing her thick sheath and massive balls against my sensitive flesh. And when she pulls out, her fat cock tugs on my asshole as the ridge of her tip stretches my hole to the brink. Then she pushes back in, shoving that beautiful fat tip into me, making me cry out.

The stretch is incredible. My mind swims as the pleasure builds from a throbbing, burning ache into a delicious spark. With every thrust, the spongy flares of her press up against something deep inside my ass that has me shaking with pleasure.

“There it is,” Maribel coos above me, her hooves clopping a steady cadence along the asphalt of the road.

“Yessss...” I hiss, rocking into her as best I can.

She starts to speed up as we turn a corner. The endorphins flowing through me have me relaxed and ready, and Maribel takes full advantage.

“Faster, harder, come on!” I call up to her.

“Giddy up!” Maribel shouts, and the next thing I know we’re full on galloping.

Her huge balls clap against my pussy and my thighs, and I can only imagine how soaked with my slick juices they are. Then I hear the wet squelch of my ass around her with every thrust and that just sets me off. The constant slap of her cock in me sends pleasure rocketing through my veins until I can’t hold on anymore. My pussy gushes around nothing as a powerful anal orgasm has my whole body clenching tight.

My ass constricts around Maribel’s pounding cock, and I hear her let out another pleased whinny as my insides milk her. I cry out my pleasure as orgasm after orgasm crashes into me, and that only encourages Maribel to pound into me harder until she’s grinding into me so deep her balls are flush against my cheeks. Her thick member feels enormous and impossibly deep, filling every inch of me, and then she explodes.

Thick ropes of centaur spunk coat my insides. It feels like buckets are being poured into me, her fat tip flaring as she pulses out her climax, ensuring her load stays right where it belongs.

“Ugh! Ugh! Ugh!” I groan as each pulse of her spunk-rocket fires a thick, creamy load of hot jizz into me. Each pulse swells my belly as it fills me with the liquid heat of Maribel’s load. My stomach bulges even more under the volume of seed being pumped into my guts.

“Fuck... that’s a good little mare...” she coos as she finally slows to a canter.

I whimper, feeling my legs trembling and my ass spasming around her still-thick cock as it slowly softens.

We make a left and trot up the road to a ranch house where our next parcel is waiting.

“I...I’ve never come that hard,” I tell Maribel, my head foggy with my intense climax. I try to adjust my sore body underneath hers to no avail.

“I know a good ass when I ride one, darlin’,” she replies. “And yours is something special.”

I blush.

The door of the ranch house opens as we come to a stop, and out walks a gorgeous older woman with her silver hair done up into a braided crown. She’s in a bright pink satin robe and has a mug of steaming coffee in her hand. Her dark eyes roam up Maribel’s horse form, taking her all in, until they find me hanging underneath and looking thoroughly used. “My, my... What’s this special delivery all about?” she asks, a smile playing on her red lips. “I don’t remember ordering such a show.”

Maribel grins. “Well, Ms. Waverly. We were running behind and I just had to pick up the pace to ensure you got this in a timely fashion.”

Ms. Waverly’s eyes twinkle. She sets her coffee on a bale of hay. She approaches and reaches out for my tits, giving them each a squeeze.

“Oh, my, my. Did you enjoy your ride, sweetheart?” Ms. Waverly asks me, her hand stroking up and down my front.

“I-I...” I stutter.

“Oh my,” she says, turning to my dangling belly. It’s then that I realize just how stuffed I really am with Maribel’s cum. I look like I’ve been overfed, my gut plump and round, a mound of bouncy flesh. Ms. Waverly’s eyes glaze over and her voice is tight when she speaks to Maribel. “And what happens now with all this cum inside this little sweetheart?”

Maribel’s shaft gives a kick inside my ass. “Well, ma’am, it would be my pleasure to demonstrate there’s still some fun to be had with it.” She tugs out of me just enough to force a fat gush of cum to leak out of my asshole. Her still-thick member plugs me back up, but not before her cum trails down the insides of my thighs and drips onto the dirt beneath us.

“Oh my god,” I cry as the changing pressure sends shockwaves through me. “T-that feels amazing!”

“Is it now?” Ms. Waverly asks with an arched brow.

“Yes, ma’am! More, please,” I beg Maribel, hoping Ms. Waverly is up to watch what’s next.

Maribel tugs out again, pushing more of her fat load to leak from me before shoving herself back inside and pumping me full. “She’s got an endless hunger, ma’am.”

Ms. Waverly bends over and smoothes a hand over my fat belly, jiggling my gut in her hand as she watches Maribel push in and out of me. Each thrust produces a fresh torrent of Maribel’s creamy spunk.

“That’s so lovely,” Ms. Waverly purrs. She presses on my belly, making the cum gush from me harder. Her other hand slips up between my thighs where Maribel’s huge cock is still hammering me full and begins to stroke my pussy.

“Ms. Waverly!” I squeal, not expecting her touch on my oversensitive cunt.

“Yes, darling?” she coos as she presses her thumb down on my clit, circling the throbbing bud. Her other hand presses my belly just so, milking every bit of cum she can out of my ass while Maribel pounds back into me. I am on the edge of a fresh climax, and it hits me all at once.

I scream out my pleasure, and Maribel cries out a second later, filling my ass up even more than before with her cum. My body spasms, shaking in my harness. Maribel’s big hands steady me by holding my tits as her hips pump in and out, giving me the last dregs of her orgasm. When her hips stop, she sighs with a pleased groan.

“Oh... that’s a delight, little filly,” she tells me. “Your plump body was made for me, wasn’t it? Lookie there, you’re still hungry for more.”

I can’t stop shaking and tears of pleasure stream down my cheeks as Maribel pulls out of me at long last, her fat tip popping through my puffy red rim and causing a gush of spunk to fall from my used hole. My ass clenches around nothing, and I know I’m a gaping, creamy mess. My body goes slack, exhausted but happy. My clit throbs as the last waves of my orgasm finally begin to ebb away.

Ms. Waverly leans forward and gives me a little pat. “Well, that more than made up for the delay, sweetheart,” she says, then stands to take the parcel.

“Have a wonderful day now, Ms. Waverly!” Maribel says.

Ms. Waverly just giggles.

And then we’re back on the road again. Maribel picks up to a gallop with ease, and the wind whistles in our ears as we rush to make the final delivery.

I feel empty, though I know I’ve been pumped full of Maribel’s seed. There’s just another hole that hasn’t been used and filled... and I have to admit it’s begging for attention.

My eyes flutter closed as I bask in the post-orgasm haze, letting the sun warm me and the gentle motion of Maribel’s gait relax me.

“Ah-ah, you ain’t gettin’ off that easy,” Maribel chides, one of her large hands coming down between her front legs to caress my breasts. I look up to her with a sleepy, dopey grin.

“Oh?” I ask. “What do you need me to do next, ma’am?” I feel a slight buzz of energy in the pit of my stomach.

“Well, now that you’re all warmed up for me,” she says with a wicked grin, “I thought we might as well fill that other hole of yours with my cum. Don’t you agree?”

My pussy throbs in anticipation, more slick dripping out to coat my thighs and add to the mess already between them. “God, yes,” I answer. “Use me how you want.”

Her smile widens as we approach the house of the last recipient. She walks up the drive of a suburban home and rings the bell, her cock back to stroking my pussy. She keeps me on the edge the entire time while we wait.

“Fuck, yes, right there, oh my god, please!” I beg quietly, not wanting the neighbors to hear.

“Now, now, don’t you come again until I tell you to,” Maribel says. “And behave, little filly. Our last customer should be here any minute now.”

We wait a minute, then two, but when no one shows up and I’m drooling from the tease of her head just barely pushing into my dripping cunt, Maribel tries again.

“Last chance,” she calls through the open door, then knocks loudly on the doorframe.

When no one appears after a few moments, Maribel plops the package on the top step and shrugs. “Well, ain’t that a shame,” she says. She smiles down at me. “Well, at least we can have one more ride on our way back to work then.”

I can only nod as her huge horse cock prods at my wet entrance and she pulls me down her shaft, stretching my pussy around her. Her massive head is so flared that it scrapes past my clit on its way in and has me gasping for breath.

“You want it, little filly?” she teases, the tip crowding my entrance.

I writhe and moan, so desperate for her inside me. “Yes, ma’am!”

Maribel chuckles and drives her fat hips forward, her dick pushing past the resistance of my inner walls, forcing its way inch by inch into my body. She is relentless with her thrusts, driving into me until that fat flare pops deep inside me, locking her in place.

“Fuuuuuck!” I wail as my eyes roll to the back of my head and my back arches, my body trembling from being stuffed so completely. It feels like she’s pushed my organs to the back of my body, making room for the length and girth of her.

“Oh yeah, little filly, now we’re cooking with gas!” she exclaims.

Her pace starts slow, but the added pressure from her horse cock is almost too much to bear. She pulls out until the fat flare catches on my rim and I cry out with a pleasured sob. She thrusts in hard, causing a thick spurt of cum to be pushed from my ass as her heavy balls swing forward, her wide sheath pushing in around her dick.

We find our pace quickly, my insides adjusting to the pressure as she works her length in and out of me with increasing speed. She finds the same deep spot in my cunt as she did in my ass and fucks it over and over, turning my legs into jello and causing my pussy to gush slick. The vibration of the road underneath us is a sweet reminder of just how full I am, and how easily she’s using me for her pleasure.

“Maribel...please...don’t stop...” My voice is rough and scratchy as I cry for more.

“I wouldn’t dream of it, little filly,” she grinds, her thrusts getting more and more intense.

My heavy belly flops this way and that as Maribel pummels it with her deep thrusts. I swear she gets thicker and longer inside me as we fuck. I am so turned on, so full, so happy that she’s making good on her promise to fill both my holes. Her powerful legs and haunches move at an ungodly pace as her front hands play with my dangling tits.

The friction is glorious. Every slap of her big body against my sore and puffy holes just sets my nerves on fire.

I can’t stop the pleasure, the screams and whines escaping me with each thrust. The noise we must be making, out in the open on this quiet residential street, is surely alerting anyone who can hear that two people are rutting like beasts.

The thought only pushes me closer to the edge, and my inner walls flutter and spasm around her. I’m so close I can taste it. “I’m going to cum!”

I feel the stretch and strain as Maribel speeds up. Her cock feels like it swells inside me, and then she cries out and I feel her first spurt of hot cum deep in my guts. That’s all it takes to set me off.

My eyes roll back into my skull as my orgasm rocks through me, my legs twitching and my mouth opening in a silent scream. I’m so full, I can hardly breathe. Maribel is grunting like a wild animal above me as she continues to fuck my cunt with an animalistic fervor. Her huge flared tip rubs the back wall of my body, and her cum continues to splash inside me, adding to the cum already plumping up my belly. My own slick drips from my pussy, unable to be contained. The feeling is so overwhelming I don’t think I’ll come down from it, each pulse of her load inside me reigniting my own pleasure and making it peak.

Maribel begins to slow, but it seems she’s unable to stop cumming. She fucks me through the aftershocks until finally we come to a standstill.

My whole body aches from the use, but the fullness and the tingles of pleasure still dancing over my skin make it more than worth it. Maribel’s chest is heaving above me as she catches her breath, her member still pulsing a little inside me. I try to breathe and take stock of how my poor body is doing under the strain, but I can’t seem to get enough air. My stomach feels like it’s up to my tits, and it certainly looks as plump and swollen.

“That...was...wow...” I pant, closing my eyes as Maribel strokes my belly. “You’re...amazing.” I burp and swear I can taste cum in my throat.

Maribel giggles, the motion causing her dick to move inside me again and another gush of cum to leak out and spill from my ass and pussy.

“Is it everything you dreamed, filly?”

I chuckle weakly. “And then some...” A pause, and I sigh. “I hate to be a buzzkill, but... I need you to take me down and let me go, before I burst or something...”

“Oh? Now?” she asks, sounding just a touch disappointed.

“I’m so fucking full, Maribel...”

“Well, alright...” She reaches for the harness, then hesitates. “Well, you know, little filly... you’ve been such a good cocksleeve, and you are all messy from our fun... How’s about I carry you back to work like this so Merin can clean you up and send you on your merry way?”

“W-hat?” My head snaps up so I can try to look Maribel in the eye, but the motion makes me burp again. “A-are you...serious right now? You...want me to go back like this? Everyone’s going to see!” Not to mention that every step Maribel takes jostles my heavy, bloated body and is already coaxing another orgasm from my worn-out holes.

“Everyone’s going to love the sight,” Maribel says with a giggle.

I try to speak, but I can’t contain another cum-flavored burp.

“Well, glad you agree, little filly!” she says. “Let’s head on back and get you back into shape, eh?”

“Wait...!”

But Maribel sets off at an easy lope back towards the routing center, leaving my heavy, cum-filled body bouncing underneath hers.

“See, now? It’s like I told you,” Maribel calls out over the wind as she speeds down the street. “We both get what we want in the end: I get to empty my load, and your parcels get delivered on time. That’s a win in my book!”

I moan and shiver under her, my clit pulsing to the beat of her hooves, already gearing up for one more orgasm before this ride is truly over. “F-fine...” I pant. “I guess that’s fair.”

Maribel’s big horse body rumbles with a deep and happy laugh. “Well now, darlin’, I think I’m gonna hold you to that!” She gallops faster, making me squeal as her thick cock hits all my buttons.

And as we rush down the road, my belly sloshing with the sweetest load, I can’t think of anything more I’d rather do.

“Come on, little guy,” I murmur, stroking my already hard shaft up and down slowly. It was late, well after midnight, and I was in the laboratory alone with the lab’s pet slime colony, or rather, our queen slime. The entire lab was silent and deserted except for me.

I stood alone, in the dark room, stroking my dick as I gazed at the beautiful, humanoid slime girl standing behind the glass tank wall.

“Come on, you can do it,” I panted, rubbing the tip of my swollen head. I let out a groan. Fuck, I was so horny. I really needed to get off.

But first, I had a mission to fulfill, an important job. My goal for the evening, to get the colony to form the beginnings of a big hard cock.

You see, the thing is, our slime colony could only form their own genitals by watching humans fuck, or at least that had been the theory until I made another startling discovery. Apparently, the queen slime didn’t need humans to have sex in front of her, she could form genitals on her own just by watching me.

It’d started a month or two ago. One night, after a long day in the lab, I had been finishing up my experiments. The other research assistants had already left for the night and I’d been alone in the lab.

After a few hours, I realized I needed a break from my research. I needed to relax for a moment. So I’d wandered into the slime colony lab to check up on them before going home.

To my surprise, the queen slime had been pressed right up against the glass of her tank, seemingly gazing back at me with her large, green eyes. I didn’t think anything of it, just smiled at her as I always did. It had been a long day and I was looking forward to my shower back at the apartment.

I’d been in a rush that day and had to leave in such a hurry I hadn’t even had time to use the toilet before rushing off. That was a big no-no in my book, especially with how much water I tended to drink in a day. The combination of the two, waiting to go and having held a lot of fluid for many hours, was too much for me to stand.

I was horny. The feeling was intense and I needed relief. My bladder was swollen with urine and I had a semi hard-on in my slacks from my need.

The toilet was down the hall, but that seemed so far away. So I figured, fuck it, I might as well piss right here. What’s the harm, right? It’s not like anyone was in the room with me. And even if they were, the only thing between the hallway and my dick was a small desk.

No one would know. So I figured I would save myself some time and get to work.

I unzipped my pants and pulled my swollen cock out through my fly. It felt so good to have it out and free. The soft flesh throbbed in the cool night air, and I gave it a few good squeezes before pointing it down into a spare plastic bottle and peeing.

My piss fired in a torrential yellow spray, and I sighed with relief. My dick shivered with pleasure and I rubbed it, just a little, until I was spent. I was feeling much better by the end, and I zipped up.

But that’s when I saw her. The queen slime, she was staring at me from inside the tank. She looked like she’d just pressed her face right up against the glass, her features were a little distorted but it was clear she’d watched me do my business. I panicked and waved her away.

But, a thought occurred to me, why not show her more?

She’d been watching me. And now that I was feeling a bit more relaxed I was getting curious. The slime colonies needed sexual interaction to survive, to keep the population up. Other researchers had discovered that, strangely, human sexuality was one of the few ways for them to breed, but watching wasn’t enough, not exactly.

So, the logical conclusion was that the queen needed to learn how to grow a cock, so to speak. We just hadn’t realized how that could be done until I stumbled on the answer that night.

She needed to see my cock.

I needed to show her.

And I wanted to know what would happen next.

The first night, all I did was show her my erection. I was already hard again and I pulled it back out through my fly, letting her see my dick for as long as she wanted.

I’m a bit on the smaller side, I’ll admit that freely, so maybe I was a bit self-conscious at the time. I’m more feminine than most men, I like that about myself and I embrace it, and so I tend to enjoy wearing lingerie and panties instead of boxer shorts or tightie-whities.

So that night, I was wearing a pretty little red lace number with a matching thong. When I’d pulled my dick out of the fly, it was a bit of a challenge to get it free from the delicate fabric. I had to hold the base of it just to get it all out so the queen could see the full thing.

And once I did, I just stood there with it in my hand. It felt good to have her staring, I realized after a few moments. I was actually getting really aroused.

My cheeks were flushed, my breath coming in short pants as I stared at her watching me with wide green eyes. Then, suddenly, I saw the most incredible thing I’ve ever seen.

There, below her waist, the slime queen began to bulge. She pushed forward, forming the base of something that looked just like a human penis. But it wasn’t, not quite.

I could see it, as if it were in slow motion. The way her translucent flesh grew outward from her body, shaping itself into something familiar. Something very, very big.

Her dick.

The queen slime had never before had the ability to create her own penis. Here she was, shaping her very own member, right in front of my eyes.

It was so erotic. Her cock grew bigger and bigger and soon I was rubbing my own as I watched. She was easily double my size, maybe triple. But even that didn’t stop me.

Soon, a huge pair of gelatinous balls had appeared underneath her growing cock and my knees went weak. I couldn’t look away as I stroked myself in time with the queen’s growing cock.

It took only seconds and then her shaft was complete. She was staring back at me and the large purple tip of her new dick pulsed.

I almost came right then. But I held off, just long enough. And once I was sure I had her attention, I took aim at the glass tank and came, splashing my hot cum all over the queen’s glass cage.

She watched the whole thing, and I swear to god I felt like her eyes never left my dick, not for a second. My heart hammered in my chest and I could barely breath after I shot my load.

It was then that I decided to stay behind at night to watch the queen, to see what she would do when no one else was around. I’d been showing myself off to the slime queen every night for the last few weeks now, stroking off while I watched her.

But tonight was special. I wanted to try something new.

I had my cock out already, and was stroking slowly as the queen gazed back. Her massive slime dick was fully formed now, the thick shaft of translucent, purple-tinted goo had a massive set of balls swinging from the base.

She had such a beautiful cock, and I’d grown a bit obsessed with watching it bob and throb against the glass every night. I would pump my cock, imaging it was hers inside me, or mine inside her, while she watched. But this evening, I’d taken it one step further and pressed my throbbing dick up against the cool tank, right where her massive member met the glass on the other side.

The sensation of the glass was nice, but it was nothing compared to the rush I got knowing that she was staring at me. It felt as if she was looking right through the wall separating us, that her eyes were focused on me, and only me.

“Oh fuck, that feels good,” I hissed through my teeth.

The queen didn’t say a word. She never spoke a word. But she did something new that night. Her cock lurched against the glass as if in reply.

I froze. Was she... moving? Her cock was pulsating in the most erotic way, as if she was humping the tank, fucking it. My heart pounded as I watched her massive dick throb and flex in time with her body.

I began to rub my own erection against the tank, slowly at first, then harder. It felt like I was touching her. I imagined that it was her shaft rubbing against mine. The heat of our flesh meeting, her cold body on my hot shaft.

“Fuck!” I gasped and shivered. I could almost feel it.

The queen seemed to be thrusting now. Her huge slime balls were slapping against the glass, sending need up my spine. Her whole body was shaking. She was really into this.

I was too. And I was so fucking close. Just a few more strokes and I was gonna cum.

“Almost...there...” I bit my lip as I held myself at the edge, trying not to blow.

And then, just as I felt my orgasm hit, something else happened. The slime queen’s cock pressed against the glass so hard I was sure it would break, and then, as if by magic, the tip of it began to secrete some strange green liquid.

The substance ran down the glass, leaving a trail of wet slime behind. It dripped to the floor, forming a pool of viscous liquid. I gaped at the mess she was making as I shot my load, splattering my cum on the wall. My legs were weak and my knees trembled.

She just kept coming too. That green slime just kept leaking out of her dick, dripping and running down her shaft until it was a steady stream flowing to the ground. I’d never seen her produce such a substance before. It looked thick and sticky and I couldn’t help but want to touch it.

“What is this?” I whispered. But I immediately knew what it was that my body wanted.

Before I knew what was happening, I was infront of the door to the queen’s tank, turning the latch. My heart was thudding so hard it hurt.

What am I doing? I thought to myself.

The door swung open with a soft click, releasing a flood of thick slime out onto the floor. It was so thick that it flowed like molasses, covering the floor in a sticky puddle. I stepped into it, feeling it squish between my bare toes. The sensation sent a shock of pleasure through my body.

I didn’t hesitate now. The queen’s cock was waiting for me just beyond the doorway. And I walked right up to her, my own cock already hard again from just being so close.

She turned to me, a hungry expression on her face. I’d never seen the slime queen’s expression quite so... hungry before.

Before I knew it I was on my knees and my face was buried in her dripping shaft. The smell of her slime was everywhere and I was overcome. My tongue lapped at her, tasting her green cum for the first time. So sweet and tasty.

Her flesh was so cool and smooth, yet pliant. She felt so good. So, so good.

The slime queen moaned and the sound vibrated her body and the huge dick I was eagerly licking. I ran my tongue over every inch of that big beautiful cock, feeling it twitch and leak more cum as I explored every vein and ridge.

“Fuck yes,” I groaned and began to stroke the base, wrapping my fingers around the thick girth.

The slime queen shivered and then suddenly I felt something on the back of my head. She was holding me there, pressing my face against her as I sucked her off. I gagged a bit but didn’t fight her. I let her hold me while I swallowed her cum, gulping it down like a good little boy. It felt tingly and cool going down my throat. And it just made me hornier.

I was leaking myself and the need between my legs was becoming too much. I was aching to touch myself but I was still stuck, face planted against the queen’s cock.

It seemed she had no intention of letting me go any time soon.

So I took a deep breath, held it, and pressed further into her crotch, burying my nose in the slime. Then I reached up and squeezed one of her huge, dangling balls.

Her reaction was immediate and intense. She moaned, a loud and long sound that sent shivers up my spine. Her shaft flexed in my grip and then a huge gush of cum spilled into my mouth and down my throat. It filled my mouth, dribbling down the sides. But I swallowed every drop I could.

“That’s it, give me more,” I managed to say as I took her cock deeper into my throat. “I want it all.”

She seemed happy to oblige.

More and more cum shot into me and I guzzled it like a hungry animal. It was thick and cold and delicious. And it was all I could taste.

My dick throbbed, painfully hard and I needed relief so badly.

I must’ve squeezed the queen’s balls a few too many times though because she finally released me. I fell back into the pool of slime on the floor, gasping for breath. My face was covered in the sticky substance. My chest and my stomach were soaked with it too.

As I sat there, catching my breath and gazing up at the slime girl, my hand snuck down to my own cock. I needed to get off again and the slime on my skin was like lube.

I grabbed my aching dick and gave it a few desperate pumps.

“That’s it baby, I’m gonna come for you now,” I said to the queen as I worked myself over.

Her expression changed. It turned smug, pleased. And then her hand was there, wrapped around my cock.

“What the...?” I gasped, surprised at the sudden contact.

Her slime was cold on my skin, and she squeezed just right. I was already at the edge and the new sensation of her hand sent me soaring.

I screamed out, bucking my hips, and shot my load into the queen’s palm. It pooled there, thick and white and mixed with her slime. Once I’d stopped spurting, she brought her hand to her mouth and licked it clean.

She stared at me while she sucked on her fingers. And then she offered her hand back to me, slick with her cum and my own.

I leaned forward to take it.

“Maybe just this once,” I breathed, wrapping my mouth around her slime-covered digits and tasting us both.

We sat there together, sucking each other’s cum off of her fingers for a few moments before she pulled her hand away. Then, with a wicked grin, the queen grabbed my chin in a slimey grip, forcing me to look her in the eyes.

“You want more, don’t you?” Her voice was surprisingly smooth. And the question she asked wasn’t really a question at all.

I just nodded, breathlessly.

She chuckled and pushed me back, her slimy hand still on my chin. She straddled my thighs, her huge slimy balls settling on either side of my hips.

I gasped, “Oh fuck... you’re not gonna... are you?”

The slime girl only smiled as she lifted my legs. “Oh yes. I’m gonna fuck you now.”

Her huge cock slapped against my small, flaccid cock and balls. The feeling of that big slimy shaft pressing against me made me whine and shudder.

“T-there’s no way it’s going to fit,” I managed to gasp.

“Relax,” she replied and rubbed that big dick of hers over my asshole. “It will. I’ll make sure of that.”

She pushed her hips forward and the tip of that massive slimy dick pressed into me. The sensation made me cry out, and my cock sprang to life again, growing to full erection.

Her precum was so slick and wet. My ass began to relax as another secretion started leaking into me, preparing me for her huge invasion.

“That’s it... let it in,” she whispered as she pressed deeper.

I whined and bit my lip as more and more of that huge dick slid into me. My eyes were wide and my mouth hung open. It felt like I was being filled to bursting. The cool slime seeped into my guts, filling me up in a way I never thought was possible.

Just when I didn’t think I could take any more, that giant cock hit something deep inside me. It pressed right into my prostate, and I couldn’t stop the cry of pleasure that escaped my lips.

She gave a pleased growl at that and pulled out slowly, almost all the way to the head. Then she slammed back into me.

I yelped, my cock jumping and my ass clamping around the thick intrusion. She fucked me like that for a few minutes, in and out, fast and hard. Each time her fat cockhead smacked my prostate I gasped. It felt like a jolt of electricity every time, like her cock was hooked up to a car battery that was being pressed straight into that spot in me.

Soon I was begging, “Please! Harder! Fuck me harder!”

She gave a low chuckle. “As you wish.”

And she really began to pound me then. She fucked me with long deep strokes, the cool slime sloshing around inside me. Every time her cock pulled out I could feel the wet squelch and dribble of slime pouring out of my abused ass, and then a second later her cock was back inside, ploughing my guts and rearranging my insides.

“Oh fuck, oh fuck, fuck,” I babbled, unable to stop myself. My eyes were rolling back in my head. Each thrust she went deeper and deeper, straightening my colon and pushing up into my guts until I swore I could see the bulge of that huge slime cock from the outside. “I can...see you...inside...me!”

She didn’t stop. She just kept fucking me like an animal. Her slimy hips slapping into my ass, her big balls slapping my cheeks with every push.

“I’m gonna... I’m...” I couldn’t even finish the sentence.

She growled and her grip on me tightened. “Do it. Cum for me!”

I came so hard I thought my balls were going to turn inside out. My body arched and shook with the force of my orgasm. Spurt after spurt shot from me, coating my chest and face with my own semen.

And she just kept fucking me, pounding her huge slimey dick into me like a jackhammer. It felt like she was trying to force another orgasm from me.

“Oh god, I... I’m... I’m cumming... again!” I gasped. And sure enough, another surge of cum sprayed from my dick.

The queen grunted in satisfaction and fucked me even harder. Her pace turned frantic. I could tell she was close too. Her cock swelled inside me, growing thicker as her orgasm approached. I swear my prostate had turned into a puffy, raw mound of flesh the way her fat cockhead was pressing and dragging against it.

My ass and dick felt like one giant bundle of raw nerves, like my whole body was a live wire ready to short circuit any second now.

The queen leaned over me, her hands on either side of my head. “Take my seed! Take it all!”

Her voice was deep and commanding. I didn’t have a chance to respond before that fat slimey cock jerked inside me. Despite her cold goo, a torrent of hot, sticky cum spewed forth.

The feeling of her load blasting into me pushed me over the edge yet again. I cried out as I came once more, this time emptying myself completely.

It seemed to go on forever. She pumped what felt like a gallon of her seed into me and the pressure built inside. I could feel my stomach and guts swelling with her huge load. I was so bloated it felt like I was going to pop. And the sensation of being filled like this made me feel like I was in one long continuous orgasm.

But it didn’t stop. Not for another long few minutes. I lay there, panting, my body twitching, while the queen milked her cock in my ass, emptying every last drop into my poor little hole.

Finally, when I thought I was going to burst, she sighed with pleasure and collapsed on top of me. Her cock softened slowly and began to slip free. When the head finally popped out, I moaned at the sudden emptiness. But then, to my horror, all that slime and cum started to leak out of my ruined ass. It was like a damn breaking and I could do nothing to stop it.

The rush of fluid that gushed from me left me feeling dizzy. And the puddle we were laying in grew larger by the second.

“Shit,” I muttered. “I think you broke me.”

The slime queen chuckled and rolled off of me, pulling her cock free and sitting up. Her hand ran along my cheek.

“It was necessary,” she replied.

I frowned and looked up at her. “What...what do you mean?”

“I must ensure my line continues,” she explained. “You will carry my eggs now.”

I felt my heart skip a beat. “W-what?”

“Relax,” the queen said, rubbing a circle on my swollen stomach.

I could feel them, now that she mentioned it. Tiny little bumps that were roiled around my fat, inflated belly.

“Oh my god...”

The slime queen smirked. “You’re a wonderful breeder,” she said. “So submissive. So willing.”

I gaped at her. I’d just been turned into a...a breeding factory. But, for some reason, the idea didn’t upset me as much as it should have. Instead, a small smile crept across my lips.

“Thank you?” was the only thing I could think to say.

The queen just smiled back. “You’re very welcome. I will take good care of you. But first, we need another slime to fertilize them,” she explained. “Or, slimes, for that matter.”

I blushed. “What does that...how do we...?”

She laughed, a deep sound that echoed around the lab. “Do not worry, my pretty little slut,” the queen said, licking a bead of slime from my neck. “My disciples now know how to grow thick, heavy cocks. You will have more than enough seed to fill you.”

As if on cue, the other slimes that lived with the queen began to crowd around us. They were all forming massive, hard erections, looking at me like a pack of starved predators.

“Ah...so it’s gonna be like that, huh?” I asked. My dick gave a traitorous twitch of interest.

“Yes,” the queen purred. She stood up, towering over me and the other slimes. “You belong to me, to us,” she gestured around to the other gelatinous beings. “And we’ll use you as many times as we need to. We’re going to make sure every last one of your little holes are dripping our spunk at all times. You’re going to be our cum dumpster for as long as you live.”

I realized that my mouth was drooling a little as she described how I was going to be gang banged by slime monsters from now on.

The idea of being filled over and over again, of having all my holes fucked and overflowing with their gooey loads... It was an overwhelming prospect.

But damn if I wasn’t a horny bitch for it.

I licked my lips. “Well...if that’s what the colony needs...” I said slowly. I sat up on my elbows, glancing at the gathered crowd of big-dicked slimes and letting out a long sigh. At least five slimes took more solid humanoid forms, each stroking their huge, drooling cocks as they leered at me. “Guess I have my work cut out for me,” I muttered. Then I smirked up at the queen and wiggled my ass. “Well come on, then,” I called, trying to act braver than I was feeling in the face of so much giant, alien cock. “I don’t have all night.”

The slimes didn’t hesitate.

Before I knew it I was being manhandled into a new position, this time with my ass high in the air and my face pressed against the floor. The queen’s hands spread my cheeks, exposing my freshly-fucked ass.

“You have a pretty little pucker,” she purred, leaning over me. “Maybe not so little anymore, but my slimes won’t mind.” Then she motioned to one of the others and a new slime stepped forward, a fat green dick at the ready.

She didn’t need to be told twice. Her green cock was smaller than the queen’s, but it was bumpy and viciously hooked, with an enormous flared head. The tip rubbed up and down the crack of my ass before pressing forward and popping past my slick rim. She forced himself into me without a pause, fucking my ruined asshole with abandon.

I gasped and clawed at the floor, but I had no escape. The slime fucked me hard and deep, her cock rubbing against all sorts of delicious places inside me. She grunted with every thrust, her body slapping against mine as her fat balls swung and slapped against my smaller, abused set.

Another smile, this time a large, super busty yellow girl with a shaft to match sauntered forward while the first fucked me. She pushed her big cock into my face, forcing the swollen head past my parted lips.

“Fuck... mmhff,” I tried to speak but she cut me off by shoving that huge cock in my mouth. The shaft tasted sweet and tangy like all slime cum. My lips stretched around that big fucker and she thrust hard into my throat, using me just as the first was doing.

I’d never felt more like a piece of meat, a toy to be used.

It was amazing.

I took the throat-fucking, gagging and drooling around the fat yellow shaft as the slime used me. And then another came up, a red one, who pushed herself underneath me. Her breasts were even bigger than the yellow ones, soft, pliable mounds of gooey slime that I eagerly buried my face between as she entered my poor, aching ass alongside the green slime.

“Fuck...oh fuck,” I cried out as they both stretched my hole beyond belief. But they didn’t stop.

Every pump of their cocks in me forced me deeper onto the yellow slime’s dick and soon all three of them had a good rhythm going. It was all I could do to hold on, to let them use me, and enjoy the sensation of being fucked so thoroughly. My own dick was a raging mess, slapping against my belly and thighs as they pounded me, spilling pre-cum all over the red slime’s soft body.

“That’s it,” the queen purred from somewhere behind me. “Take their seed like a good breeder.”

I felt the green slime tense, and then she came. Her fat hooked dick jerked as a massive load of hot cum painted my insides. She flooded my already sloppy ass and then pulled out, making room for another.

I lost track of how many times they fucked me that first night. My ass was left gaping and oozing cum, my throat was raw and my face was a sticky mess, but I’d never felt more alive. By the time the last slime had taken her turn and the queen had mounted me once more for good measure, the sun was peeking through the blinds of the lab’s windows.

When they were done and their cum throughly mixed together in a big sloppy mess inside my bloated stomach, the queen had me stay behind and shower in the slime pools that formed at the bottom of her tank. The cool slime felt like a healing bath, and I could have sworn my ass closed up a little. She even gave my spent cock a few gentle strokes before I fell asleep in the tank with the others, her fat dick buried to the hilt in me while we all slept, keeping her growing eggs from slipping out of me at night.

I couldn’t be any happier and looked forward to serving the queen and her slime colony until the end of my days. I was their willing cum slut, their submissive breeder.

And they loved every fucking second of using me. As did I.

I don’t think there could’ve been a more successful experiment than this one.

The slimes grew in number after that, each more hung than the last, and each one with the same need to empty their swollen nuts into my waiting hole.

The lab may have found its new breeder, but it still has plenty of other fun projects to try out. And I plan on being there for every one of them.

It’s all part of being a scientist, right?

I look out of the car window as we head towards the grocery store. The weather’s hot, so hot that I swear the tar on the road has turned soft and malleable, bouncing underneath the wheels of my mom’s van. As the car slows towards a four-way stop, my mother puts her hand out to me from her driver seat, grabbing hold of the hem of my yellow, cropped blouse and tugging it down. She looks over and sighs.

“Couldn’t you at least try to put a shirt on with a few more inches on it? That, or, better yet, an actual pair of jeans? You look like you’re wearing Daisy Duke hotpants,” mom says with a sigh. I don’t understand what she’s going on about, since my blue dragonkin step-sister, Paige, wears much shorter shorts than mine. Her ass cheeks hang out from beneath the frayed ends of her denim shorts and her cropped top barely conceals her huge breasts. Hell, her futa cock bulge is far more noticeable than my little femboy clitty. Not that it matters to me, but I don’t get why she cares so much.

“He’s fine, Mom, look at how adorable our little puppy is,” Paige coos from her spot behind Mom, leaning over the center divider to look at me in the passenger seat. She gives me the biggest grin.

“Yeah, Mom, leave me alone; I look hot today!” I retort back to her, leaning back so I’m closer to Paige. She smells good, like a freshly lit match, and it always makes me feel so cozy. Since she’s a dragonkin, the smell comes with the territory.

“I swear... I’m so happy you two get along so well, but why do you egg each other on?” Mom says, focusing on the road. “We have enough problems going out to the store without you two encouraging each other to look so...” Mom’s eyes get wide, a nervous look crosses her face.

“Sexy?” Paige asks, finishing Mom’s thoughts.

“I was gonna say, scandalous, but yeah. Why you two are in agreement when it comes to these things is beyond me. Can’t we have one outing without your wardrobe choices sending people into a tizzy?” she asks, giving us a pouty, puffed-cheeked expression. We both laugh and look at each other, snickering as we chatter, continuing towards the store. Mom’s had a bit of a struggle trying to acclimate to the world ever since she married Paige’s father, Mark. Mark is a full-blooded dragonkin and so is Paige. I’m, as they so aptly put it, a puppy boy. My mother is an elf, with long, pointed ears and an hourglass figure that gets her a lot of attention. I have my dad’s dog looks and my mom’s curves, and I’ve just come to accept that I make a pretty hot femboy.

“Relax, Mom, I’m just messin’ with ya. Besides, he is so adorable, I just want him to flaunt it!” Paige giggles and pulls me towards her from behind, tickling my sides and causing me to let out a squeal as we pull into the parking lot.

“Paige! Knock it off or we’ll never get through today’s errands,” Mom snaps at my step-sister, parking the car. We get out and Mom heads to the front of the store for the shopping carts.

“You can be such an embarrassment,” I say to Paige as I bend over to get my little, black backpack from the back seat. She pinches my butt and causes me to yip and drop the bag in the middle of the parking lot.

“You love it,” Paige says to me. I turn and scowl at her, and then see the grin on her face as she puts her hands up.

“Alright, I’m sorry, that was mean, I shouldn’t have done that,” she says, laughing a little.

I turn towards my bag, but she steps around and puts a hand out. “No, no, I’ll get it for you, okay?” I frown, but watch her bend down in those tiny shorts to retrieve my backpack, and my jaw hangs open. She hands the bag to me as she rises up, her smirk bigger than it’s ever been, and I swear she just thrust her hips out at me a little. I lick my lips, taking the bag and hurrying past her towards Mom.

“Fuck, she’s such a tease,” I whisper to myself.

I help Mom with her bags as we go into the store, feeling Paige’s presence behind me, and then a slap on my ass as she catches up.

“Oh, did you drop something?” she asks. Mom looks over her shoulder at us, a worried expression on her face and I know we have to behave now.

“No, and keep your hands to yourself or else, I’ll tell Mom you’re the one who put the ‘Dragon Dildo of Glory’ in her nightstand,” I retort back. Paige’s face goes pale and she quickly apologizes. I shake my head, letting out a little chuckle at having one over on her and we move on into the store. We go our separate ways, with my sister going off towards the produce to grab some stuff and me staying with Mom in the clothing section.

I grab the shopping cart from her, telling her to have fun while I browse the racks, and she gives me one of those exasperated mom looks, but with a grin.

“Stay out of trouble, alright?” I nod and head down the rows of clothes.

As I peruse the latest crop tops, I feel something rubbing against my ass and I look back to find my sister standing there, holding out one of the giant, two-foot-long dildo boxes they have for sale.

“Here, take this,” she whispers, shoving the box into my hands. “Meet me in the changing rooms in five.”

I look back at her, but she’s already walking away, wagging her scaly blue tail and whistling nonchalantly as she heads towards the home goods department. I look down at the box, my mouth falling open. The thing is fucking huge! The picture on the front shows the bright blue silicone cock in all its glory, with little nodules around the sides to help stimulate. My ass clenches just looking at it, imagining how big it is inside. I bite my lower lip and scurry off to find the changing rooms.

The last thing I’m expecting when I get into one of the changing stalls is my sister already waiting there, leaning against the wall.

“What the-”

Paige throws her hand up, covering my mouth and dragging me in, shutting the door behind me. “Shut it, puppy,” she whispers into my ear, a low growl escaping her lips. “Drop ‘em.” She steps back and puts her hands on her hips. I know what she’s trying to do, but fuck if I won’t resist her. My little cock is hard already, seeing her there like that, her little shorts hiked up and I can just see the underside of one of her massive boobs. She sees me checking her out and she wets her lips, a gleam in her eyes that makes me weak in the knees. I swallow hard, unzipping my shorts and letting them drop, then taking off the lacy thong underneath, exposing my hard cock to her. She tilts her head, clicking her tongue.

“You’re already leaking pre? Damn, you’ve really got it for your step-sis, don’t ya?”

“I’m not... it’s not-” I stammer out my denial.

“Oh please, don’t even pretend like you aren’t imagining what I can do to you. Look, you’re so ready,” she steps in close, grabbing hold of the shaft of my cute little cock still growing from my sheath and gives it a light tug. I whimper and put a hand against the wall to steady myself.

“You like when big sis plays with you like this, don’t ya? And you wanna see what the ‘Dragon Dildo of Glory’ is all about?” she asks with a grin. She squeezes my cock again and I nod, not even realizing it, my eyes shut from the sensation.

“That’s what I thought. You wanna know the best part?”

“Wh-what?” I stutter, looking down at her, my cock throbbing.

“Turn around.”

I do, presenting her my ass and feeling her fingers rubbing and pinching my cheeks. Then, suddenly, I feel it, her massive cockhead slipping in between them and prodding my little hole.

“Sis-” I whimper, gripping the wall tighter, my face heating up with lust and shame all at the same time.

“What is it, baby? Do you want me to put it in?” she asks, grinding her hips, rubbing it along my crack. I don’t even hesitate when I say, ‘yes’, pushing myself against her to feel more of her.

“Then ask me nicely, pup,” her voice low, dangerous, and so full of lust. I push myself back into her, trying to get her cock to slide into me, but she slaps my ass.

“Ask,” she growls, pulling my hips back to her as she rubs my crack with that fat shaft of hers. I whine, burying my head against the wall of the stall.

“Sis, please, I need you, please fuck me.”

“With what?” she asks.

“Your cock! Your big, fucking dragon cock! I want it inside of me so bad, please!”

“Oh, is that it?” she asks. Her hand slips over my hips, fingers pressing along my hard cock and causing my hips to buck forward.

“Yeah, oh gods, I wanna feel your thick cum inside of me,” I gasp, arching my hips back for her. And that’s when I feel it, the push against my entrance, so insistent that it almost hurts. I push out, feeling the pop as my asshole stretches, making way for her cockhead to fill me. The pleasure of the sensation causes my body to convulse and I nearly fall forward against the wall.

“Mmm, so good,” she coos as I grip around her cock. She leans down, her body caging me, her teeth grazing my neck. Then, slowly, she thrusts her cock, working herself in little by little, the girth and length so intense I’m already moaning. I reach my hand down to grab my own clitty cock, pumping it while my step-sister’s cock works inside my ass, making a tight little fuck tunnel of my butt for her to thrust into. I feel her hips slap against me as she pushes herself deeper inside. The bulge of my lower stomach pushes out, making me look a few months pregnant.

My prostate is getting stimulated with every little thrust, making my body shiver from pleasure. I’m whimpering her name, over and over, wanting so badly for her to flood me with her cum, I can barely hold it together.

“Please, Paige, fuck me harder,” I beg her, but she holds her thrusts still, teasing me by making small grinding circles, grinding against me from inside and pushing her cock against my inner walls.

“After I fill you with my cum, you’re going to wear that plug inside and carry it all the way home, understood?” I nod my head in earnest, looking back at her. “Then I’ll reward you.”

I thrust back into her, feeling that massive dick shove into me, balls deep and causing stars to appear behind my eyes. The wave of pleasure is so great that I nearly topple us over, my body going slack. Then she pounds into me, making my hips bounce forward as her hand wraps around me, jacking me off in time with each thrust.

“Yes! Yes! Fuck!” I cry out, unable to stop myself as my ass clenches and releases around her massive cock. She covers my mouth, thrusting harder as I moan and whimper into her hand.

“So loud! Keep quiet, puppy, or I’ll stop,” she growls.

“I can’t! Fuck, I’m gonna cum!” I pant into her palm. Her thrusts grow deeper, more insistent, and her breath hitches. She’s getting closer too, I can feel it. She’s holding my mouth shut with one hand and holding my cock with the other. Then she squeezes hard around my cock as her own explodes inside my ass. I feel it, the hot stream of cum spurting into my hole as she hilts me and I’m pushed over the edge, cumming hard in her hand. Her cock pulses, over and over inside me as my own pathetic squirts of cum dribble over her fingers and down to the floor. She pulls me against her chest, whispering soothing words as she rides out the rest of her climax, making me shiver from how sensitive I’ve gotten.

My ass is on fire from the pounding and from the massive load she just let loose inside of it. I can feel it swirling around with the thick cock still plugging the exit as she pulls out a bit then pushes back in to let my walls close around her again.

“So good, so full,” I groan as I rest back against her, her breasts soft against my back.

“You like my big cock?” she asks, kissing my neck. I nod, enjoying her embrace for just a few minutes more before she pulls back and away from me. I stand straight up and watch as she tucks her deflating cock into her shorts. I turn and look up at her with a half-lidded, contented gaze, licking my lips as I feel my ass dripping with her cum. She opens up the dildo box and pulls it out, tossing the plastic to the side and running her fingers over the girthy toy. It looks almost identical to my sister’s dick, with the same little nodules and bulge towards the head of it. She turns and holds it out towards my hole, letting the cool, silicone tip push against my already sore, gaping hole. I feel her finger slide around my rim, pushing some of her cum back inside.

“Hold this for a sec,” she commands, and I do, watching as she picks up the box and places it underneath the bench. She turns back and looks at the dildo, slowly pulling it from my fingers. Her eyes meet mine and her lips curl into a smile.

“You did so good for me, little pup, that I’m going to give it to you slow,” she says as she begins pushing the massive toy into me. The stretch is different from anything I’ve ever felt before as it spreads my ass open again. Her eyes go wide as she watches it disappear inside and her tongue lolls out of her mouth.

“Oh wow, that’s really sexy, watching your tiny, puffy hole just take it all in.” I moan out as she pushes it all the way to the hilt, feeling it displace some of the cream buried in my ass. “Can’t wait to watch you walk with that buried in your guts.”

She pulls her hands away and the base sits snug against my hole, locking all of her cum inside my ass. I lean over and pull up my shorts and panties. My stomach is bulged out and it’s really hard for me to stand up straight, but when I do, I look like I have a little baby bump. Paige kisses my forehead and wags her tail excitedly before giving me a hug and grabbing the door.

“Don’t take this out for anything, not until we’re back in my room. Understand?” I nod, taking the hug, my face buried into her massive chest. I can barely move without feeling every single bump and ridge stimulating my insides.

“You’re gonna look after me, right?” I whisper, barely able to talk.

“Of course, pup,” she says, pushing away and looking into my eyes. “Just remember, I’ll be watching to make sure you’re a good puppy.” My cock jerks and my ass tightens around the toy and I fail to suppress a moan as my prostate is stroked by one of the dildo’s many supple beads. She opens the door and steps out, and then turns back one last time before heading out of the changing room.

I take a breath, letting myself get used to the sensation before I step out. When I do, Mom walks by absentmindedly with a few bags on her arm, looking at her phone.

“Oh good! Paige told me you were trying on some shirts. How’d they fit?” I feel my heart skip a beat and I know my face must be red. She looks up, a smile on her face and then a look of confusion. She tilts her head, looking at my stomach and I look down myself to find that my blouse has risen up and now my little pooched belly is showing.

“I, uh-” is all I can say.

“Huh, well, anyway, I found a pair of shorts for you to try on since Paige said you really wanted some, I’ll put them in here-” she pushes a bag into my hands and turns her back to me. I take in a big breath and slowly close the stall door.

I can hear the two of them talking outside like I didn’t just get fucked out of my mind. My legs feel weak, like jelly, as I look at the new shorts. I like them enough, but I can’t risk putting them on now, so I just take them with me. The pressure of sitting with the plug up my ass makes my dick jerk in excitement. I let out a low moan, grabbing a hold of the edge of the bench as I make a tiny movement. A little dribble of cum trickles down my leg and I quickly wipe it away.

My eyes close at the sensation; the stretch, the fullness, the little beads pressing into each and every nerve. I’ve never felt more full before, nor have I had the thrill of doing something so lewd out in the open. I bite my lower lip and think about the ride home with my big sis sitting beside me, knowing her seed is locked inside and her huge toy stretching me open. A tiny whimper leaves my mouth and I let out a long sigh. I hear a knock on the door and look up as Paige sticks her head inside. She smiles that knowing smile and licks her lips. My ass clenches around the toy.

“Mom is heading out to get more bags, want me to come in there and help?” she asks, already stepping through.

“No! I mean-” my voice cracks and I see her laughing. I put my hands over my face in embarrassment.

“I’m only teasin’ ya! C’mon.” She grabs my wrist, pulling me out of the dressing room with her, walking past a couple of people on the way out and not paying them any attention. We walk over to Mom, who gives us a smile and holds up another bag. We check out and head back to the car with Paige opening the trunk and setting all the stuff in the back. Mom climbs in the driver seat while I head into the passenger side, holding my breath for far too long. I need some space right now so I don’t embarrass myself, especially when we hit some of the speedbumps leaving the parking lot.

Somehow, I keep it together despite the sudden stops and bumps on the road, each one grinding that dildo in a way that sends jolts of pleasure through my body. It’s such an overwhelming feeling that I fear I may cum again. I take deep breaths, looking out the window, counting the minutes as we get further towards home. I look down and my eyes catch the little bump my belly is making and a shudder wracks my body as I watch the little bounce every time the road becomes uneven. I hold my hand over it and close my eyes.

“What are you thinking about?” I hear Paige’s soft voice as she puts a hand on my knee from the back seat. Her touch is electric and I squeeze my thighs together.

“I can’t- not right now, sis,” I plead quietly, but she rubs my thigh in response. Mom glances over at us with a suspicious expression, but I just give a tight smile and try to hold still while my sister massages my thigh and moves up to rub against my swollen belly. My toes curl and I clench around the toy again.

“Don’t move too much or your shirt’s gonna ride up and Mom’s gonna get the show of a lifetime,” she teases, biting her lower lip. My cock twitches and I feel it spurt into my shorts a little. Her fingers tap lightly against my belly and then she pulls her hand away, sitting back. My whole body is trembling by the time we pull into the driveway. Mom gets out first and heads towards the back of the car to get the bags as I unbuckle and get ready to dash inside. Paige stops me as I reach for the handle.

“You’re not just gonna leave your big sis hangin’ are you?” she says with a pout.

“Huh?”

“Stop being such a little pup and get going. We got things to do, and a plug to take out,” she whispers as her hand slips down to cup my balls and tug. My legs quiver as she plays with me, pressing the tips of her fingers into my bulging abdomen and causing me to gasp. My mouth hangs open, unable to make a sound, my face burning hot from arousal.

“Oh gods, you look so fucking hot right now,” she moans into my ear before she lets go and climbs out of the back seat, waving at Mom as they take the groceries in the house. My whole body is a shaking mess of want and frustration as I clamber out of the car. My shorts are absolutely soaked with pre, my dick never fully going soft, just waiting for the moment Paige touches it again so it can shoot its tiny little load. I reach the back of the car and grab what I can before going inside.

When I’m finished bringing in the last bags, I slip up the stairs and into my room, closing the door behind me.

I toss my stuff onto the bed and quickly remove my shorts. The way the toy has shifted inside me makes it so that I can’t really sit down, so I lean against my wall and wait. I can hear Mom downstairs, calling up to say that she’s going out to the hardware store real quick and that she’ll be back before dinner, and not to wait on eating. I hear my step-sister call back that she’ll let me know before she leaves, and I just smile, knowing my moment is coming soon.

I only wait a few more minutes before she bursts in and shuts the door, locking it behind her. She turns towards me, and there’s a fire in her eyes I’ve never seen before. She pulls her shirt over her head and her heavy tits bounce, nipples already hard. My hand slides down to my own cock, gripping it at the sight of her.

“So good, my little puppy boy, taking your big sis’ toy so well. You’ve been walking around with it for nearly an hour,” she says in a husky tone, sauntering over towards me as I watch, unable to move. “Did you think about my big cock inside you the whole time? Filling your tight little ass?” She gets up right next to me, taking my chin in her hand. I simply whimper but nod my head.

“Yeah, I could see how much you liked it,” she grins, running a thumb over my lips. I open my mouth to suck it in and her grin widens. “Do you want your reward, little one?”

I nod, licking her thumb and moaning for her.

“Good,” she says, releasing me and pulling me over to my bed. She has me lie back, keeping my legs up. Then she kneels between my legs, taking my knees and pushing them back so that the toy begins to shift, slowly working its way out of me. It pushes a few drops of cum out of my little clitty as it comes out another fraction, spilling it across my tummy and Paige is right there to lap it up as soon as it’s out. My eyes bulge as the pressure increases and decreases across the length of my guts.

“Ahhh!” I groan, tensing hard, each inch squeezing more of my puppy seed out until the whole length is lying across my belly in a puddle of cum. And then I feel it, the empty ache and the rush of liquid spilling down the back of my legs as her huge load finally comes flowing out of my gaping, ravaged hole. A few tears leak down the side of my head as she sets my legs aside and leans down, kissing and licking around my twitching rim.

“Oh, you poor baby. I bet you really felt all that, huh?” she says before licking a strip from my crack up to my balls and making me twitch and buck. “Now that you’re all stretched out,” she says, slipping off her own shorts to expose her growing dragon cock to me. “I think my little puppy deserves a reward, don’t you?” I stare wide-eyed at the thick member, seeing that it’s a little bigger than the toy, even in its half-hard state. My hole flexes at the sight, clenching down and releasing as she grabs it, stroking it to its full length.

“You don’t mind if I just use you for a bit, do you?” I shake my head, still mesmerized. She slaps her huge cock down next to my teeny-tiny clitty, and I see the drastic difference between the two of them and a thrill runs through me. She grabs hold of the back of my thighs and I instinctively grab my legs and pull them towards me as she leans down and slowly guides her fat cock to my stretched-out pucker. The first touch is enough for me to cum again, spewing dots across my stomach with a tiny squeak. My whole body shudders and then goes slack as I watch her work the head of her cock inside of me. Her eyes are glued to the place where we meet, her thick tongue hanging out as she pushes inch after massive inch of herself into my fucked hole. She doesn’t stop until I feel her balls pressing against my ass and her cock bulging my belly out even farther than before.

“You feel so good around me. Such a tight little hole you got.”

“Oh, Paige,” I whine as she pulls out, and then pushes back in. “Don’t go too hard.”

“Oh, sure thing, little pup.” Her hips find a gentle pace as she starts to fuck me with deep, but slow movements. I lie back, watching as the bulge slides up my stomach, listening as my squelching asshole makes noises each time she hits deep. Then she picks up the discarded toy and puts it on my chest, looking up at me as she fucks me. “Open,” she says, and I do, letting the wet, cum-soaked toy slide past my lips and press into my mouth, until the little nodules are hitting the back of my throat, causing me to gag around it.

She licks her lips at the sight, her hips snapping a little harder, going faster. “Suck it, go on, suck it for me.” Her eyes are watching my lips as I move around the toy, trying to get more of it down, tasting her and me in the process.

“That’s right, taste how nasty you are,” her hips go wild as she fucks into my ass, “and how fucking good you feel wrapped around me like this!” I know she’s going to cum again and I reach down, stroking my useless clitty cock while the dildo bobs in my mouth, causing me to salivate. My hips lift and she leans over me, bending me in half and pressing my legs towards my head as she rails me hard. The toy slips from my mouth and I gasp for breath.

“Fill me, do it, fuck me full of cum, please, I can’t-” I don’t finish my words. Without a second to wait, she begins thrusting hard. Her fat balls slap against my sore cheeks, the sound so wet that I feel my face flush a hot red. Every few thrusts, she buries her dick deep inside of me to grind against my already sensitive prostate. It has me hard again in seconds and all I can do is lay there and watch as my own cum speckles back down over my chest and face, and hers bubbles out around her thick shaft as she moves.

“Fuck me, fuck me, fuck me!” is all I can chant as she pounds me into the mattress, my legs held in a vice-like grip by her massive hands. I’ve never felt more alive than I have right now, taking her cock like the slutty little puppy boy I am, feeling my hole gape for her while she rails me hard and deep.

“What a fucking cocksleeve, you love my big dragon cock so much. Gonna cum in you again, and this time, I’m gonna make you watch,” she says, thrusting in deep, grinding her hips down and rubbing the head of her cock against the sweet spot inside of me.

“Yes! Yes! Please!” I whimper, barely able to talk as my body shakes.

Her eyes narrow on mine, her grin becoming wilder with each passing second before I see it, and I feel it, that second load, splashing up inside my guts. She was holding back last time because of our location, but not this time. I’m screaming, nearly losing my mind as she pours what feels like a gallon of spunk into my once tiny asshole. My body jerks, twitching uncontrollably, as my balls try to pull up again for a second release, but only dry heaves come.

I watch as my belly extends out and out and out, and still she cums. Tears pour from my eyes, not from pain but from the utter bliss of being so fucking full. Her face is wild above me, her fangs bared, growling as she floods my insides with more cum than should be possible. She keeps grinding long after she’s spent and finally comes to a stop, a stupid smile on her face.

“That was... fucking amazing!” she finally says, resting with her cock in me. I can feel her heartbeat throbbing through her softening cock until she sits up and slides her cock out of me. A torrent of cum starts flowing out of my gaping asshole as soon as she’s removed her plug and I watch as she leans over the edge of the bed and grabs something before plopping down beside me. She hands me the huge butt plug she just fucked me with, but my eyes go wide with fear.

“No, Paige, no, I can’t!”

“Oh yes you can and you will.” She takes the toy and guides it back to my stretched, sloppy hole and pushes it back in. “Trust me, you can do it. And you’re gonna wear it until bedtime. And after I’m done with you tonight, you’re gonna have sweet dreams with me inside of you.”

I look up at her, mouth hanging open as she kisses my forehead and snuggles in close. My hands move down to feel the taut skin of my cum-stuffed belly and a smile crosses my face as she whispers.

“That was the best fuck of my life. And I’ll make it better next time if you let me.”

I sigh, the feeling of being absolutely fucking complete coming over me as I cuddle close to her.

“Yeah,” I finally say, “let’s do that.” And as her hand wraps around me, stroking the puppy ears on the top of my head, I can only dream of what her next surprise will be.

Whatever it is, I know it’s gonna be fucking amazing. Just like her.

I drift off to sleep, with her cum inside and the dildo plugging me up, and I couldn’t love my dragonkin step-sis more than I do now.

Warning: this story is for readers 18+.

The scent of my step-mom’s pheromones fills my nose and I wince at how horny I feel.

I shouldn’t be near her room, I know I shouldn’t be, especially knowing how bad her heats have been. My birth mom is on a business trip, so she’s got no clue as to the amount of stress it’s putting my step-mom through.

I know she hasn’t been taking her heat suppressants because I can smell her heat from a mile away…I’ve been able to smell her for days. I try my best to hide away in my room and focus on my schoolwork but even then it’s not easy.

My deer tail flicks back and forth as I stare at my door, my whole body growing warm. I glance around my room for a moment. It’s a mess. Clothes tossed aside, school books everywhere, my laptop on my bed with half-finished papers and notes I can’t bother reading. The smell of my step-mom has me going crazy too.

I step towards my door and look down the hallway to hers. It’s cracked open so I know she’s alone in there. I shouldn’t do it, but the lamia pheromones have my whole body screaming that I need to do it.

I step into her room and find her on the bed, her dark hair tossed around the pillows. She’s got on a nightgown and her coils are twisted up around her body, hugging herself close. As a lamia she’s got the upper body of a woman, large soft breasts and a trim waist, some parts of her skin covered in a dappled pattern of black, white, and gold. Her lower half is a long snake’s tail; she’s usually black and white with that same gold, but right now it’s more gold in places. I’ve seen it before and I know it’s because she’s in heat.

Her tail has twisted around itself and she’s whimpering. I bite back a gasp and I can feel my own kind of heat between my legs. As a deer hybrid I’m a little different from most people. My top half is very much a human girl, a little on the small and slim side but I still have all the curves where I’m supposed to, including a huge pair of tits. My bottom half though is more deer. I have a fluffy white tail that’s usually kept close to my rear. I have long legs ending in deer hooves. And of course I have a large fluffy white ass.

She looks up at me as I slip into her room and shut the door behind me.

“Oh, hey,” she gasps, pushing herself up and the covers fall from her chest. Her dark eyes are wide as she looks at me and her pupils grow. She’s so in heat she can’t even control the primal side of her.

I glance down, seeing the lumps in the covers.

“You ran out of heat suppressants, didn’t you?” I murmur.

She bites her lip. “Yes,” she hisses at me. “I thought I had more, but I ran out earlier this week. And-”

“And what?” I ask. My voice sounds rough and throaty to my ears.

She glances aside, her dark cheeks turning pink. “Nothing else is working,” she grunts.

I walk over to her and place my hand on her cheek. She looks back up at me with a desperate, worried expression.

“Why didn’t you tell me?” I ask her. “I could have helped.” I turn her face so she has to look at me. “I want to help you,” I whisper.

She whimpers and wraps her arms around me. Her strong tail coils around me as she nuzzles into my neck. Her touch and affection send shocks of need down my spine and deep into my gut.

“No, no, you can’t,” she whimpers. “Your mom...it wouldn’t be right.”

“My mom isn’t here and I know she’d understand if she knew,” I growl. I wrap my arms around her, stroking my fingers down her back. She whimpers and shudders, her tail tight around my thighs.

She pulls back and looks up at me. “But-”

“You’re family to me, it’s ok,” I kiss her on the cheek. “Let me help.” I kiss her again. “I can tell you need it.” I push the blankets down and reveal her swollen cocks, both of them bulging from her swollen cloaca. Like a true lamia she was born with twin cocks, both are thick and hard and red. A single dribble of cum comes from both and slides down her shafts.

“Oh god, no, not here, not now,” she groans. “You shouldn’t be looking.” She covers herself again.

I push her back onto the bed and strip her of her gown, joining her on the mattress. Her soft breasts bounce free, her dark nipples thick and hard. I’ve always wanted to touch them but never could until now. I cup my palm to one, feeling its weight in my hand.

“Let me take care of you,” I murmur to her. I push my thigh against one of her shafts. It feels hot and I can feel the pulse of her heartbeat.

She grunts and bucks up against me. “I-I want you so badly,” she moans, “but...but-”

“I’m here now,” I coo, pressing harder against her. Her pre starts to wet my thigh and I growl, a soft, lustful moan slipping from my throat.

She takes my hand and makes me touch her other shaft. She shivers and looks into my eyes with pure need. “It’s going to take so much,” she pants, “I just...it’s not stopping.” She covers her face in shame and her tail constricts around my legs. “I can’t stop leaking pre,” she sobs.

I kiss her neck and then her cheek, sinking into the bed. “It’s ok, I can take care of everything,” I whisper into her ear.

She sighs and nods, leaning into my touch as I kiss along her neck.

I kneel down between her coils and pull the blanket away. I can already feel myself soaking my underwear as her cocks spring up and throb.

“I’ve never done anything like this before,” I whisper up to her.

“Me neither,” she murmurs back. She strokes her palm over my cheek and tucks my hair behind my ear.

I smile at her as I take one of her cocks into my hand. Her hips twitch and buck and she shudders with relief. “You’ve needed this, huh?” I purr to her.

“I just want to cum and get rid of this feeling,” she sighs, closing her eyes and shivering. “You’re so warm,” she moans.

I lick my lips and take the other cock into my palm as well. It’s long and thick, hard, yet still soft somehow. She’s dripping so much pre the sweet scent makes my head feel light.

“I bet your knots are really big,” I giggle.

She hiccups and sits up, her eyes wide. “Don’t-!” she pants.

“I’ve seen my mom’s deer cock by accident, and I was sure yours had to be similar in size,” I whisper as I squeeze the base of both her dicks and she gasps. I can feel the hard little ball at the base that will grow huge once she cums. I’m starting to get nervous, but I keep telling myself I can do it.

I open my mouth wide and take one of her shafts down my throat. She screams out and arches her back.

“Oh fuck,” she snarls. “Careful,” she whines. Her fingers tangle into my hair and she thrusts her hips. Her cock is already leaking so much pre it’s dribbling from my chin and down my neck.

I close my eyes as the taste washes over me. I suck hard, swallowing down her sweet pre and moaning for her. Her hips buck more and the tip of her second cock rubs against my cheek, slapping me like a tentacle as she moves.

“That’s so good,” she whimpers. “Baby girl, that feels so fucking good.” Her voice is dark and ragged with her desires.

I open my eyes and look up at her, taking the second cock in my hand and stroking it as I suck the first. I swirl my tongue around and her whole tail begins to twitch. Her tail then lifts up under my skirt and I gasp in shock, my mouth popping free of her cock. I look down to see her tail has slipped into the side of my panties, pulling them down. Her coils twist between my thighs and I gasp as she starts touching my puffy little mound.

“You’re so wet too,” she snarls at me, a low hiss in her voice. She pushes her tail into the tight cleft of my mound, the tip of it pushing through my pussy lips with a pop. “You’re dripping,” she growls.

“Mommy,” I moan. My fingers squeeze her cocks as she pumps her tail inside me, pushing against the back of my pussy before pulling back and thrusting in again. Her tail hammers my sopping hole and all I can do is moan and cling to her dicks for dear life.

“I shouldn’t be doing this,” she hisses. “Fuck,” she whimpers. “You just-” she moans and her head drops forward. She looks at me through the strands of hair that fall from her messy bun.

“Mommy,” I whisper to her, “don’t stop.”

She groans and kisses me, licking into my mouth and tasting herself on me. She then sits up and strips my clothes away. As she pushes me down into the bed I gulp and stare up at her. She looks like a goddess, her twin cocks are hot against my thighs.

“I need you,” she hisses, her dark eyes blown wide, “I need to cum now!” she snarls, pressing close. “Can mommy use her baby?” She kisses my neck.

I whine, unsure now. “I don’t-”

“Don’t worry,” she kisses my cheek and rubs her cocks against me. She smears her slickness across my thighs and mound. She dips down, slipping a cock against the lips of my deer pussy, and the other between my cheeks. “I’ll take good care of my baby girl.” She kisses my cheek again as I whimper in shock and slight terror.

“M-mommy?” I stare into her dark, lidded eyes.

“Shhh,” she coaxes as her thick, long cocks spread me open like red tentacles. She pushes deep inside me, her heat making her frantic and desperate, all the while kissing and petting me. She eases me, kissing my brow and petting my cheek as her cocks hilt deep inside me. “So big, aren’t I, baby girl?” she moans.

“So deep, mommy,” I mewl as she stretches my ass and pussy wide around her. She pulls out and pushes back in, grunting into my ear as she goes deeper and deeper.

“You can take more, right, baby?” she pants in my ear. She reaches between us, groping my breasts as her hips start to roll in waves.

“Yes,” I sob in pleasure as her cocks drill deep into my belly. I can feel her, like she’s pressing up inside my ribs. I rub my belly and bite my lip to hold back my pleasure-filled scream.

“I’m so full, Mommy,” I cry out.

Her thick coils wrap around my waist and pull me down, sinking both her cocks deep into my belly. “I want you to take every drop,” she snarls in my ear.

She thrusts hard and I yelp as a wave of pleasure seizes my body. I can feel her, the tip of one of her cocks pushing inside and roiling around in my womb. The other is buried so deep into my belly I swear it’s going to push out my throat.

“Fuck!” I squeal, tongue lolling from my mouth as I begin to drool in utter bliss. I’ve never felt anything like this, and I’m surprised I’m enjoying it. I can feel her swelling at the base of each cock, both her knots growing rapidly inside me. I struggle as they press against my tight holes, straining to get in and lock her into me.

I wail, grasping at her, my whole body shaking. I stare up at her with wide eyes, seeing a strange smile on her lips. She licks them and places her palms on my chest.

“Just a bit more, baby, just a little more and it’ll be better,” she snarls into my ear.

I whimper, feeling like I’m already bursting as is. I can’t imagine what it’s going to feel like once her knots pop in. But her voice is soothing, and I start to calm down again.

“I can do it, mommy,” I whisper, my fingers clinging to her strong arms.

“I know, baby,” she growls. “I know.” Her lips curl and her tail squeezes around me tighter. “Let’s make mommy cum.”

The base of my ears rings and I hear a dull pop as her knots push in. I gasp and whimper, wriggling and twitching. She cries out and arches her back, her mouth opening wide.

A flood of cum fills me. I scream as my pussy and ass flood and the knots on both cocks keep everything inside. I gasp and moan, feeling every drop that shoots inside me. I look down, watching as my stomach stretches and swells, filling with her thick cream. Her cum sloshes inside me and gushes through my womb, stretching my belly and making it tight. I’m moaning and sobbing in pleasure, my pussy convulsing and clenching hard on her cock.

“It’s too much!” I wail as her hot seed rushes inside me. My stomach stretches and rounds. I look like I’m already halfway to pregnancy.

Her tail slithers up my neck, curling around my throat as she kisses me, silencing me as I feel her pulses again. I squeak and gurgle as she stuffs more and more of her seed in me.

“You’ll take it all,” she snarls into my mouth. “You’re going to take every last drop I can give you and you’ll be happy.” She kisses me again. “Because you love your mommy, don’t you?” She smirks. Her tongue laps down my cheek. “I’ve seen the way you look at me and how you act when you smell I’m in heat.”

My eyes widen and I whimper into her kiss as my womb, stomach, and guts keep expanding. She’s already pumped so much inside me and still I feel more of her cream flooding me.

She leans back, her hips jerking as she grinds in me, keeping her knots in place. Her dark hair has fallen down around her face in wild tendrils. She licks her lips and bites them, watching as my stomach grows. The cum inside me feels so hot, it feels like she’s put molten lava in my womb.

“I’ve been waiting so long,” she whispers. Her coils playfully squeeze my overfilled belly and I sputter and squirm under her.

“Mommy,” I moan in a daze, “I-ah!”

Her finger presses to my lips to silence me again. “It’s ok,” she coos at me, “you can take it, you have been dying for it, remember? You wanted to help me and this is the only way.” She places her palm to my belly; it feels so taut and stretched she’s able to see the way her fingers press in.

“So beautiful,” she sighs. Her palm presses into my breast and she gropes it gently, making my nipple stiffen.

“I’m so full, mommy,” I groan. I feel so heavy. I can’t move and my legs are completely numb, but I’m so drunk on pleasure I don’t think I’d care either way. “I can’t-”

She hushes me again. “You did so well, baby girl.” Her finger traces around the taut rim of my bellybutton and then presses against the inside. I yelp and then giggle as she swirls her finger inside.

“It’s almost done,” she murmurs, “I’m not as potent as your birth mommy, but you’ll still end up pretty full.” Her hands knead into my swollen stomach and it makes the cum inside swirl around. The pressure presses against every raw nerve I have down there, sending jolts through me.

She pulls her hips back and I whimper as her thick knots stretch my tender holes. She pulls out more and more, and her cream leaks from my pussy and ass. I gulp and look at her; I have no idea what she’s going to do next.

She grunts as she lifts her hips higher, her cocks popping free and flopping onto my swollen belly. Her cum dribbles from her tips and onto me as a wave of her seed rushes out of me in heavy waves, coating my thighs and the bed. It smells so thick and good my head swims in the fumes. I sob with pleasure and relief as my belly shrinks back down, although I still have quite the pooch. It’s a small bump, like a little pouch of cum she left behind for me to remember this.

I gulp, looking down as her tail plays in the mess while she rubs her fingers through it and licks herself clean.

“That was fun, wasn’t it?” she purrs as she gazes up at me.

I nod, unable to find my voice.

Her coils tighten around me again, keeping me snug as her mouth goes to my breasts. She sucks and nuzzles, making me moan with delight. My back arches off the bed as I gasp.

“Good girl,” she moans. “You did so well.” She pets down my still swollen belly. “How do you feel, baby?”

“Sticky,” I pant.

She smirks, licking the cum from around my bellybutton. “I know, but you look beautiful like this, all stuffed and warm.”

I smile at her as she crawls back up, kissing me softly.

“I’m sorry I lost control, baby girl,” she murmurs.

I touch her cheek and smile. “No worries, mommy, you were good to me. You took care of me.”

Her cheeks darken and she glances aside. “Well,” she kisses my brow, “maybe we’ll have to take care of one another again next time. If that’s what my baby girl wants?”

I nod. “Yeah,” I whisper. “Next time.”

I close my eyes as her fingers pet my hair. I feel safe and happy there with her and I wouldn’t ask to be anywhere else.

I had hoped to help her with her heat, but I wasn’t expecting how much I would like it, too.

Warning: this story is for readers 18+.

The mansion was supposed to be empty.

My brain, still only half-functional while I woke up, scolded me for my stupidity, still wrapped in the same cocoon of silk that had engulfed me when I’d been caught.

The owner of this place was supposed to have left the country a few days ago for a job, supposedly taking the whole household with them. I’d thought if they’d left no guards, it would be easy pickings if someone like me wanted to make off with some expensive, luxury goodies. I had made good progress, eyeing an expressive set of earrings, when I’d been snatched off the ground by an unseen assailant and wrapped into what felt like a bondage suit.

I felt like I’d been trapped in it forever, fading in and out of consciousness. I was waiting there in my cocoon of what felt like silk, having fallen asleep in my little bondage suit after a struggle to break free, the warmth of it feeling strangely comforting to my lithe figure.

When the owner’s large, feminine feet clicked to a halt on the hardwood in front of me, I knew that she must have been at least ten feet tall by comparison to my body in the cocoon.

“Ah, we’re awake. And who do we have here?” a husky voice chimed.

I felt myself being pulled up by the silk around me, my cocoon dangling as I swung back and forth for the view of the person who captured me. With the dim light, my vision wasn’t very clear, and my feline eyes squinted as they adjusted.

Two beautiful pale breasts the size of watermelons obscured my vision first, straining in a custom silk top as the lower, spider body came into view behind them, eight long legs flexing and stretching before she was facing me directly.

I was eye-to-eye with a giant arachne; with how beautiful she was and how immaculate the mansion was, I imagined that she had to be wealthy enough to take all of her staff to accompany her, only returning to her home in the evening for some sort of special reason that only she was aware of.

The arachne smirked at my reaction, letting my body dangle with an ease from her web, the sticky threads holding my neck, stomach and legs aloft from the floor.

“Anything to say for yourself, my little trespasser?” she said. Her voice had a certain sexiness to it, and it drew my eyes from the gorgeous body that she possessed to her beautiful eyes, her raven locks flowing freely behind her, reaching just above the thorax of her lower, arachnid body.

There were plenty of arachne out in the world, but most of them were plain at best, with half of them working in silk farms. Many of them didn’t have the good looks that she did, or even the fortune to live in a place like this.

I opened my mouth to speak, only to be cut off as a wad of webbing covered my face and I was suddenly pulled downward, my feet meeting the floor. The same silk then bound them together as my body was hoisted up once more, hanging above the floor and facing a giant, wooden bed. It was in the shape of a massive spider web, with an oval center big enough for me to lay flat inside.

“I hope you weren’t expecting to do much looting today, or any other day for that matter.” The arachne spoke confidently as she reached over to run her hand through my hair, her giant digits caressing my cheek through the silk mask covering me. “Catgirls are supposed to be stealthy, aren’t they? And yet you came in through the front door and triggered my web. A bit dimwitted, are we?”

I tried to respond, but all I got out was a muffled reply of protest as a silken gag stretched inside my mouth. She was clearly having fun with her little capture, a devious look coming to her eyes as she lowered me toward the center of the spider web bed.

“Naughty girls don’t deserve to speak to their superiors,” she teased, dangling me over the center before my cocooned body settled in, sticking to the strands. The silk that cocooned me started to dissolve and part, my vision and mobility returning. The webbing that stuck to my body kept me firmly in place on the mattress of silk, my arms and legs manipulated and spread out in an ‘X.’

That was when she came into full view as I struggled on her silk sheets. She was dressed in the finest garments: a long skirt that ended halfway around her massive, spider lower body, with a beautifully crafted halter top that fit her bust perfectly. The smile on her face grew as I glared up at her, trying to get a foot free to kick her, even though I knew that it wouldn’t do much with her giant size.

“Now, you’re probably asking yourself what I’m going to do with you now that I’ve caught you,” she said, propping herself up on a pair of legs as she faced me directly, her beautiful eyes watching my reactions as she reached down to pick up a length of silk cord. “But since you came into my home uninvited, that means that you’re my property to do with as I please. How does that sound?”

All I could do was nod eagerly.

My tail was swinging and my ears were laid back flat as she began to undress me with her cord of webbing. I watched helplessly as my shirt came apart into shreds, my breasts falling free and perking up from the chill of her silk home. She licked her lips as the rest of my clothes were pulled apart, my slender legs left bare as well as my pussy and ass for her to see. She removed the gag at my mouth with a flick of her wrist. Her eyes narrowed as her fingertips caressed my bare belly, wandering down to cup my pussy in her giant palm, forcing a shudder from my lips.

“So small and delicate, yet with all the fight of a wild animal,” she continued. “That will change after a night with me, though.”

Her hands went to her own clothing, slowly unlacing her bodice and letting her breasts fall free. They looked even larger to me than they did before, her long legs lifting to push down her silk skirt and kicking it aside to give me a clear view of her abdomen, which sported two large protrusions.

I watched with a mixture of lust and horror as what looked like two massive cocks stood at full attention, twitching slightly with each beat of her heart. Each of them looked as if they were meant to please someone with a cavernous pussy and a hungry asshole, and my eyes only stared in silence and fear at them.

“That’s right, little kitten,” she crooned down at me, her hand wrapping around one of her massive members while the other pointed toward the ceiling. “Aren’t they impressive? I’m sure they’ll fill that little catgirl pussy of yours and that tiny backdoor until you won’t be able to walk straight.”

I felt my pussy weep as she spoke, my heart beating faster in my chest. There were a million thoughts running through my head. I’d been caught by a futa arachne with two massive dicks, both clearly meant for me. I also couldn’t help but marvel at how big they were; I wondered if my whole hand would even be able to close around them, and I desperately wanted to try. My head was swimming and my legs started to shiver as her hand came to my face, stroking along my cheek.

“You can make a sound now,” she whispered. “And if you don’t, I’ll just start shoving them in there while you’re silent.”

As if my body was possessed, my mouth opened to let out a whimper of a moan. Her giant palm lifted to caress my head and I could only nuzzle into it as I panted softly.

“See, kitten?” she giggled softly. “It won’t be all that bad once we get started. Just lay back, take a deep breath, and I’ll take care of the rest.”

I could only moan softly in response, my legs struggling slightly to part themselves more, giving a bit more view to the apex between my thighs as she positioned herself over me.

One of the two appendages came to my pussy, spreading the lips to meet the entrance of my folds. It wasn’t like a cock, I realized; there was no head at the tip, and it was thinner than the other with a slight curve. The other appendage looked much fatter than the other, but was the same length, both easily reaching from my crotch to above my head when they were together.

I wanted to ask about them, but with my mouth freed and my mind preoccupied, I was just moaning in anticipation. I could feel the tip of the larger appendage kiss at the entrance of my pussy, coating it in my juices as she rubbed its length between my legs. It was hard and felt good against my sensitive folds, and I wanted her to push it in already.

“Do you know what this is?” she asked, smiling down at me.

“N...No,” I gasped out, bucking my hips as much as I could against the silk, wanting her to push in just a little. The wet tip brushed against my clit and sent shockwaves through my body, and I was losing my mind with just the barest touch.

“This one is going to fuck your pussy and womb to no end,” she whispered, making my heart race faster as I gasped and shook under her ministrations. “But it’s not my cock. It’s my ovipositor, made especially for little sluts like you who have hungry, empty wombs ready to be bred.”

My eyes went wide with her words, both with terror and lust. She was going to fuck an ovipositor into me? Was she really going to lay eggs in my pussy?

Before I could protest, she slapped the other, smaller appendage against the entrance of my asshole, and I moaned, shaking under her. “Now this,” she said, “is my cock. It’s going to be ruining your asshole for a while, kitten. After you take my eggs and get stretched to your limit, my cum is going to shoot so deep and fill you to the brim, you’ll be leaking from your gaping hole for weeks.” She smiled as I whimpered and moaned for her, my head falling back as I let out my most wanton call. “How’s that sound, you little whore? You’re gonna take everything I give you like the good little kitten you are?” I could hear the arousal in her voice; it was clear that she wanted this as much as I did.

I nodded my head rapidly, pushing my hips up again. “Please! I want it! I want your eggs and your cum!” My pussy clenched as I finally admitted to what I wanted, and the smirk on her face grew even bigger as she finally lined the head of her ovipositor up with my pussy.

“Mhmm...so vocal now. Only question is, do I take your pussy first? Or your ass?” The appendages both pressed against me at the same time as I arched my back, the sensations driving me wild.

“Fuck! Both at once! I wanna take it all! I’m your property, please, stretch my holes and make me yours!” I whined out, looking up at her with need in my eyes. She groaned as she heard me begging, pulling her hips back a bit as she looked down at me.

“Anything my little fuck toy wants, then,” she grunted, her voice sounding strained with pleasure as she pushed slowly against both of my holes at the same time. I could feel her heartbeat through both appendages, my breath coming in rapid pants as the thinner cock slowly opened my asshole while her massive ovipositor pried my pussy lips apart. Both entered me in unison, her voice coming out in deep groans of pleasure as they slowly made their way even deeper inside of me, both weeping pre as my body gave way for her.

I gasped as my stomach looked slightly distended from the combined size of her cock and ovipositor pushing into me, a delirious smile on my lips as my insides stretched to accommodate her until finally her cock bottomed out inside my ass and my pussy met the wider base of her ovipositor.

“I knew that you would take it all,” she sighed with bliss, her giant body looming over me. She started to fuck me then, slowly drawing back before shoving forward again, hilting herself inside of both of my holes. Her thrusts were a burning pleasure that had me practically drooling as I looked down at my body. With each thrust, I could see the outline of her ovipositor bulging my belly each time, and I wished I could touch it, to feel her inside of me even as she fucked my body raw, but all my limbs were tightly fastened by her web.

Her movements grew faster and she leaned down, her lips crushing against mine in a sloppy kiss while she growled and moaned from the pleasure. Her tongue forced its way into my mouth as my eyes rolled back, overwhelmed from how good her double penetration felt.

I could feel both appendages throbbing as she kept moving in and out of my oozing holes, both of them so hot from her arousal and buried so deep within my body. I cried out as my first orgasm approached fast, my pussy clenching around her ovipositor as my body shook underneath her.

“Oooh, you feel so good, kitty!” the arachne moaned out as her thrusts continued. “Your body feels like it’s gonna break around my cock!”

I couldn’t form a reply as I came, my cry turning into a silent scream while my vision went blurry around the edges. The sensation of being so thoroughly filled sent my mind into a frenzy of ecstasy, my legs trembling as I clamped my eyes shut tight and let the pleasure consume me. It felt like my soul was trying to escape my body from how much I was twitching from my orgasm, her appendages still moving inside me and stretching me beyond what I ever thought possible.

The stretch in my womb sent me into another wave of orgasmic bliss. It wasn’t like when she was fucking me, but as her cock kept a steady, deep thrust within my spasming walls, she started to squeeze around her ovipositor, forcing the first of what I knew would be many eggs deep into my uterus.

“F-fuck, h-here they come!” she growled against me, her voice almost feral with lust. Her body suddenly stilled against me and the base of her ovipositor expanded against my entrance to lock inside of my abused pussy. I felt my womb swell with the first couple eggs settling within my walls before the second, third, fourth, and more came to follow. I couldn’t make any other sound than guttural moans as her cock swelled and twitched inside my asshole as my pussy was being filled. Each egg that pushed past into my tight womb must’ve been pushing against her cock, bringing her closer to climax.

My insides were stretching more and more to accommodate all of them, and I had long lost track of how many were being deposited within me by the time the last one finally passed into my womb, leaving my body looking as though I were beyond fully pregnant. The pressure inside of me was delicious as my mind floated away in euphoria from my egg-heavy womb, and it wasn’t long before she started to move once more, making me let out a lewd moan.

“How do they feel?” she purred against my lips, her tongue coming out to stroke over them. “My little babies nestled within you? Can you feel them inside of you?”

“Yes!” I practically sobbed out, my head lolling as she fucked me harder with the added fullness of the dozens of eggs inside me. It felt as though it wouldn’t be much longer before she came inside my ass, her whole body shaking on top of mine. I couldn’t even focus my vision on her beautiful face while she stared down at me, her ovipositor moving slower, but more deliberate now as her cock picked up the pace. She growled out in pleasure before suddenly hilting herself inside of my stretched-out holes once again.

“I’m gonna fill you, kitten,” she panted out as the eggs that filled my womb suddenly wobbled and swayed. I could feel them shifting inside of me as a warm rush of fluid suddenly shot deep into my guts. Her cum roared freely inside me and I let out a strangled cry, a shaky smile coming to my lips as her cum continued to pump into me without stopping.

My belly stretched even bigger with each spurt of cum that erupted inside of me. Her hands gripped the bed beneath my back as she let out a feral cry, her eyes shut tight while the heavy weight in my stomach swelled and filled even more. The feeling of the hot semen sloshing with the eggs within me made me feel like my pussy might explode from just the thought of it. My ass clenched down around her throbbing length as if trying to keep it deep inside me forever, not wanting to waste even one drop of her cum that spilled inside.

Her legs shook while she continued to empty her massive load, her arms then wrapping around me as though to keep my body pressed tight against her own, ensuring not a single drop of her cum would escape from my stretched asshole while the last of her massive orgasm came to a blissful end.

My insides felt more than full; I knew someone could’ve mistaken me for being pregnant with quadruplets by the time her cock stilled in my asshole, her moans slowing as she panted in exhaustion over me. She finally pulled her ovipositor from me, leaving it gaping while it dribbled out the slick ooze she’d been fucking me with. I whined and shifted as she did so, not wanting her to leave my pussy, but she was quick to reassure me.

“Don’t worry, kitten,” she whispered to me, her hand coming up to stroke my face. “I’ll fuck your pretty pussy again soon. Wouldn’t want those eggs to get lonely in there, would we?” I could only shake my head weakly and smile up at her as she then removed her cock from my ruined asshole. Cum spurted out of me the second she was no longer plugged up inside, but soon both gaping holes were stemmed by her webs, sealing the openings to ensure I kept in as many of her eggs and as much of her cum inside me as possible.

“There we go...” she groaned softly, running a hand over my full stomach before stroking my side. “Stay just like that for me until I’m ready to give you some more of what you need. How does that sound, my new property?” She giggled as I gave a weak nod, my eyelids drooping as the warmth of her fluids swirled inside of my body.

Her palm left me for a moment, only to return with her soft breasts pushing against my lips. I heard her breath hitch as I started to suckle and lick at one of her nipples, and I could have sworn I felt a gush of more of her cum between my legs as I did so.

“That’s it, you little whore,” she sighed, her eyes hooded as she smiled down at me. “You’re my perfect little cum dump, my gorgeous egg sac.”

Her words made me moan and squirm against the webs holding me, my pussy clenching around nothing as I sucked hard at her nipple, wishing for her cock and eggs inside of me once again. I hadn’t felt this full in my life, and my body was still crying out to be even more full than it already was. I never wanted to be empty again as I came down from the high of sex.

I just wanted to remain like this with her forever.

“Don’t worry, my pet,” her voice rumbled from above me. “Mommy has plenty of eggs to fill that needy little body of yours. And you’re never going to leave again.” Her smile turned into a wide grin. “That mansion out there belongs to you as much as it belongs to me. You just better hope that your body can handle all that you’ll have to give it...”
