Work Text
The Sex Dungeon requires all clients to show their Adventurer's License before stepping onto the expansive floor, a converted dungeon tucked away beneath a crumbling tower on the edge of town. It caters to adventurer's who, due to certain encounters while out questing, find themselves unable to return to the usual forms of sexual pleasure. There are enchanted strap-ons that temporarily become real and fuse to the wearer, able to knot or lay eggs or flood someone with cum; there's a stall dedicated to potions that extend orgasms, reduce the refractory period, and increase the amount of cum produced; down every lane, there's at least one table with five or more dildos molded off of phalluses from real monsters; and some vendors even rent out certain tamed monsters.Youmin works at a lingerie store that sells anything from living bodysuits to sets of plugs and headbands that meld into real cat ears and tails (among other things). He usually comes into work wearing a (non-living) lace bodysuit and tiny leather shorts, covered from fingertip to neck. A choker hides the edge of the lingerie at his neck, high-heeled boots showing off the toning of his long legs (pale, because as much as he tries to get out, he works long hours). His hair he keeps swept back with a touch of gel, to show off the faux tear-streaked eyeliner and heavy red blush beneath his eyes. He makes a lot of sales, always glad when he helps someone find something they'll like. Most of all, he keeps himself as non-judgemental as possible (which is in the contract of every employee at The Sex Dungeon) because Youmin's dream has always been to help people. Even if that way is just selling them sex toys and pretty clothes, which may or may not also be sex toys.He likes his job, honestly, even if he did kind of stumble into it. His coworkers are nice, and he gets a hefty discount on products from his own stall, reduced pricing anywhere else. His boss is nice and leaves him to his own devices for the most part. And Jeongmin drops by most days with some treat or other food to try.Youmin must confess that he doesn't really know Jeongmin very well. They've never really talked, not for more than an exchange of brief greetings anyways, but the food always comes when Youmin is getting hungry an hour before his scheduled lunch break. He sometimes wonders if he doesn't get hungry then because Jeongmin brings him food so his body expects to have a snack, but Jeongmin's little treats are always delicious. So, he doesn't mind it much. And it helps, too, that Jeongmin is achingly handsome, sharp jaw and sharper eyes, always in overalls and boots, sometimes gloves. He leaves his arms bared, his sides showing, and he must spend his breaks going on walks outside because he's deliciously tanned.He doesn't know Jeongmin well, but he has an attractive smile and is always nice, so Youmin likes him well enough. So of course, when Jeongmin drops by near close and asks if Youmin would help him with some product testing, Youmin blushes heavy and agrees. He doesn't work for tomorrow or the day after, either, so it'll be fine if he ends up somewhat indisposed. They talk a little on the way over to Jeongmin's stall; turns out, he's a monster handler, deals a lot in higher maintence monsters. Slimes (who have to be cleaned thrice daily at a minimum), harpies (who need their claws filed constantly and their feathers meticulously preened), even two mimics (who are at this point so rare out in the world as to be classified as 'Endangered' by the POMF (Preservation Organization for Monstrous Fauna).One of the mimics, Jeongmin says, is the genuine, real thing. They keep it sedated and well-fed, and Jeongmin's boss--a small man by the name of Hong Doeui, with big eyes and an ever-serious expression that belies his warmheart--been studying it to make safer, artificial mimics that are practically indistinguishable from a real mimic. That's the second one they have, the first testable result of all their research and prototypes. Jeongmin has been tasked with making sure it works well and has already been inside it. Of course, multiple trials are always helpful and even preferred, which is why he's asking Youmin for help now."So, this is it. Right now, it uses simple commands. A snap to activate, and then a list of programmed commands for someone outside the chest to guide the experience." Jeongmin pats the lid of the mimic, its exterior made to resemble an elaborate chest of a whitish metal with red trimmings. It's massive, comes up to Youmin's hips and undoubtedly has enough space inside to comfortably fit a person. He's definitely intimidated by it, but he's way more... intrigued. "And, uhm... I think it may work better with a femme body, so if you're willing, I have this ring that's enchanted to swap the wearer's sex. No permanent changes!" Jeongmin digs around in his pocket and reveals a ring to Youmin, a simple black band, slim and lightweight. He's heard of this sort of thing, even sold a few pieces with sex swap magic woven into them, but he's never tried it himself. If it helps with Jeongmin's work, though..."I'll try it out," Youmin says mildly, taking the ring and sliding it onto his forefinger. It fits snugly, and a low tingle fizzles through his body, following the hollow tracts of his veins. The tingling gathers in his chest and between his legs, almost itchy as his body starts to change. Too curious to resist, he watches as his chest gets softer, small breasts growing until the lace of his bodysuit is stretched a little bit tighter. There's not much difference, but it's enough to fascinate him. Conversely, his shorts get a little looser, and he finds himself able to rub his thighs together with no resistance in the middle. Nothing else changes, and the static beneath his skin disappears completely."So... you think it'll work? Can you do it?" Youmin presses his lips together, trying not to blush so obviously, and nods. "Okay! It'd be best if you step out of your clothes, so the mimic doesn't ruin them, but I can keep them for you until after. And if you'd like a robe, we've got some you can use." He nods again, picking at the hem of his shorts for a couple seconds before looking up at Jeongmin and smiling."I'll be fine without the robe, just bring me to whatever room we'll do the testing in and give me a couple minutes to get used to myself." Jeongmin agrees easily and whistles sharply, prompting the mimic to sprout a sort of snail foot and follow him as he leaves the room. Youmin trails after them and is led to a room in the back which is filled with soft mattresses, pillows and blankets on one half, a wide, clear space left in the other half of the room. Jeongmin carefully nudges the mimic into the empty space and whistles again, and the mimic reverts back to the normal chest."I'll be waiting outside." Jeongmin leaves the room without waiting for an answer, leaving the door slightly cracked. Youmin stares after him for a moment before turning back to stare at the mimic. Artificial. So, plastic and latex? Silicon, maybe? Or is it some sort of lifeform animated by magic, like a construct or homonculous? Will he even be able to tell it's not a real monster? If he can't, then it fulfills its purpose, doesn't it?Youmin hums to himself as he starts undressing, taking off his boots and laying his choker over them before peeling out of his leather shorts. Looser now, but still tight and clinging, warm from his body heat. Molded to the shape of his body after so many wears. Which leaves him in the lace bodysuit, delicate, intricate red lace that matches his hair. He undoes the clasps at his nape and crotch and carefully pulls it over his head, nails filed blunt to keep from catching. It's slow-going, unwilling to risk ripping even with the stretch and give of the fabric. And it's strange, the subtle sensitivity as the fine lace drags over his nipples. He doesn't usually get much out of his nipples being messed with, but maybe something about the ring has made them more sensitive. The bodysuit hangs smal and limp from his hand, and he folds it into a tiny square to set on top of his folded shorts.He gives himself a moment, just feeling the cool air on his skin, before raising a hand to cup a small tit, squeezing gently. He's always been thin, erring more towards slim once he wasn't such a kid anymore. He thumbs under his nipple, dragging over smooth skin and feeling nothing, like he's used to. But when he pinches it gently, there's a sharp sort of pleasure-pain he hasn't felt before. It's not much, but his nipple stiffens and aches a little more when he squeezes again, harder. He doesn't hate it.Better, though, and sending definite curls of pleasure through him is the gentle pulse between his legs. He reaches down, his arm brushing against his stiff nipple, and slides his fingers against his pussy. Smooth, shaven skin for the most part, but there's a light thatching of soft hair that he usually shaves off. Had shaved off. Interesting. Finds his own clit and touches it sparingly, slides two fingers into himself and brings them back out a little wet. The slick clings and stretches as he separates his fingers. It has a deep, musky scent that isn't wholly unfamiliar. The arousal is softer than he's used to, not quite so present and demanding.Youmin looks at the mimic again, resting innocently immobile in front of him. He would never suspect that it was a mimic if he found it out in a dungeon, might not even be put off by the size of it. Some people like big chests (ha). He swallows thickly, and tosses Jeongmin's name back over his shoulder, still staring at the mimic when Jeongmin comes back inside, this time closing the door. Locking it, "For privacy," he says when Youmin casts him a questioning look. He doesn't move until Youmin nods, smiling and coming to stand beside him."Ready when you are," Jeongmin says easily, still smiling. He really does have such a pretty smile. Youmin nods and gestures towards the mimic."Go for it." Jeongmin nods, gently touching Youmin's shoulder before moving forward and snapping, knocking on the lid of the mimic. Its maw gapes open, revealing blunted teeth and a long, tentacle-like tongue. The interior looks fleshy and wet, just like a normal mimic. With another snap and a short, crisp, "Grab," the tongue whips out and wraps around Youmin, pulling him into the chest and shutting the lid so quickly he feels dizzy. The mimic wastes no time in wrapping a tentacle over his eyes, the skin rubbery and sticky against his skin, and pressing a thick tentacle past the seal of his lips. It's already wet when it slips in, the fluid rich and almost smoky in flavor, and Youmin feels himself relaxing as it seeps down his throat. At the same time, though, the throbbing between his legs grows hotter and stronger, and his entire body seems to heat, skin wetting with sweat in the oppressive, damn air inside the mimic. It makes his breath feel short and his heart beat harder.The aphrodisiac has his body lax and soft, meaning it's easy for the mimic to twist him around until his heels are pressed to his ass and held apart by thick, slimy tentacles, his wrists bound behind his back and tugged down until he can feel his back bowing. Like it's trying to make him push out his tits, like it's trying to make them look bigger.He gasps wetly as a thick, blunt tentacle presses against his vulva, trying to works its way between his folds. It's clumsy, though, smearing wetness all over and doing little more. Smaller tentacles pull his labia apart, holding him open so the bigger tentacle can't possibly miss its target. At the next pass, the tentacle pushes into his cunt without issue; the smaller ones withdraw, letting his folds slap softly against the thick intrusion. And it keeps pushing into him, slow and steady as he gasps and arches into the tentacles that start touching his nipples. He's not sure he's ever taken a cock so thick; the stretch is almost painful, the tentacle so wet it slides in easily. And then the tentacles fondling his breasts start undulating, twisting around his nipples until they're stiff, even a little puffy. And he almost whines as they withdraw, but they're quickly replaced by proper suckers that seal over the peaks of his tits and suck his nipples up into their centers, squeezing and pulling until his gasps turn into moans and he jerks away, pressing himself down onto the tentacle in his cunt.He almost, almost thinks that'll be the end of it, but then tentacle starts properly fucking him, dripping wet and making a sucking noise at every withdraw and push back in. The thrusts are hard, jolting his body up into the suckers, which quickly start pulling at his nipples at a punishing pace. It's so overwhelming that he's not even moaning anymore, instead choking on his own spit with every thrust. The throbbing between his legs is so intense he can't think past it, heat swelling fast beneath his skin. He doesn't have the right words for it, would usually say he's so hard he's going to pass out.The stretch stops hurting as the tentacle's slime cools on his skin, making a mess of his ass and thighs, leaving only the delicious weight of it in his gut. His nipples throb as the suckers keep pulling, a sharp pain shooting through him before settling. And then he hears a creak and is being jostled roughly, lifted into the air. It's cold all of a sudden, and he hears a sharp intake of breath. "Jeongmin?" There's a whimpering edge to his voice and a cooling wetness on his cheeks that makes him realize he started crying at some point. He sniffles and cries out at a particularly sharp thrust from the tentacle, the suckers pulling harsher than ever at his tits as pain and arousal swirl through him in a confusing mix."Yeah, you're--doing good. Really--hot," Jeongmin chokes out. With a snap and a bitten out command, the mimic draws Youmin back inside and clatters shut.He whimpers, pressing into the suckers as they start letting up, moving slower. No amount of whining and begging and pushing his chest up into them makes them keep going, though, and they shift into gently massaging his tits and doing little else. The tentacle buried in his cunt pulls out too, leaving him gaping and empty. As the mimic holds him firmly in place, no more rough jolting as he's being fucked, no more harsh sucking at his tits, he slowly becomes aware of a growing ache. There's a pulsing in his chest, his nipples throbbing in time with it, and tiny sparks of pain crackle along the soft flesh. Heavy. His tits are growing heavy. Softening, swelling. What is it doing? Is it putting something in him? Is that even possible?The suckers squeeze a little harder at his swollen tits, and without warning something shoves into his nipples. His back arches, tits pushing again into the suckers in an attempt to soothe the pain. He gasps, panting heavily, heavy-chested as the suckers pull away, leaving him entirely bereft. He almost cries.But then he's being lifted, turned over with his head down and his ass pushed up in the air, and the thought that Jeongmin could open the mimic again to check on his progress any time now has his pussy clenching and leaking thick globs down his thighs and belly. He isn't sure what happened, but his tits hang heavy like this, the ache growing sharper with the pull of gravity tugging on them. Skin overtaxed, stretched out to accommodate whatever they've been filled with. Is it cum? Just goo? Had it been disappointed his tits were so small? The thought that the mimic might've wanted his boobs bigger makes heat rise to his cheeks.He's not surprised when, once again, a tentacle slides into his cunt as his nipples start to be messed with, like the mimic is trying to distract him. The tentacle is thinner, though. The things on his nipples are rougher, circling his nipples and touching nothing else, a little sticky-slick as they start to twist round and round. It hurts; he loves the way it feels, tugging on the sensitive, puffy flesh. When they squeeze in against him, these rough sticky things, something hard pushed down through the centers of his nipples grinds into him. It's almost like a piercing, but something isn't quite right. It's like the mimic has plugged him, almost. As the thin tentacle presses against something deep inside him that aches softly, he jolts away and his tits jiggle a little. Wet, hot, throbbing weight. If it went to the trouble of filling up his tits, wouldn't it make sense for it to plug them too, so he didn't lose anything?The tentacle goes just as slow as the bigger one had when it was stretching him out, pushing through the aching resistance--cervix, his groggy brain provides--while the tiny, twisting mass of tentacles rubs at his nipples until they're heated and sore. It hurts. The plugs grind harshly against throbbing flesh, and he's drooling with every little movement, groaning low and rough. And then the tentacle is shoving deeper into him, pulling a shriek-squeal out of him. The tentacles at his nipples drop away, and the only movement is his own for a long moment, the heaving of his chest sending subtle trembles through his plump tits.Something thick and round presses up against him from inside the tentacle. It's round, a perfect little orb. An egg, Youmin thinks, can't imagine what else it would be. It seems like it's too big, like it's not going to fit, but then it pops through, and Youmin moans so loud his throat hurts, shaking as he feels the egg squeeze through his vagina. It reaches that point of resistance--his cervix--and presses, and presses, and keeps pressing until the ache builds higher and brings tears to his eyes again, and presses even harder until his cervix gives way and the egg shoves through. It hurts every second, too big through too small a space, but still it squeezes in and settles in his uterus. His womb. He has a womb, too, doesn't know why he wouldn't, and the mimic is forcing its eggs into him. He wails as an egg bumps up against his clit, so far untouched, and he's been drawn so thin that he instantly topples over the edge. This is an orgasm, there's no doubt about it. The clench of his cunt draws the next egg further into him, helps it squeeze through his cervix into his womb with a bright, throbbing pain, and then he hears the creak of the mimic opening again.Jeongmin moans outright as Youmin is hoisted up in to the air again, ass still raised, tits swaying from the movements. The eggs start coming faster, pressing into him before the previous one has fully forced its way through his cervix, and all Youmin can think is that Jeongmin can see everything. The stretch of his cunt as the eggs slide into him. The way his tits bounce with each little thrust the tentacle gives, helping the eggs into their new home, settled warm and sweet in his womb. Can he see Youmin's nipples, too? No doubt puffy and bright red from the cruel treatment. Are the plugs decorative at all? Can Jeongmin see the little jeweled ends peeking out of him, an obscene reminder of the depravity being done to him? The things he's letting be done to him?He throbs his way through another orgasm, getting off in a bad way to Jeongmin watching him. Swears he can feel Jeongmin's eyes locked onto his cunt, his breath at Youmin's ear, his fingers helping to stuff a trio of eggs into him. It's like shoving anal beads into his pussy, sopping wet, cumming again, squirting around the bulge of the thickest egg yet. Youmin cries out, wailing high and crackly as the egg is shoved forward by more behind it. Too thick, still, can't make it in. The tentacle draws back and thrusts in, hard, presses two more eggs through to his womb--now aching, swelling, filling just like his tits--but still this bigger egg is stuck outside him. Grinds up against his clit and draws out his orgasm until he swears it will never end, that he'll just be stuck here like this forever. Suspended in the air, Jeongmin consuming his gorging body, giant egg like a wolf's knot grinding against him, trying to force its way inside him. And he'll always feel the cresting pleasure throbbing through his soft flesh, coursing through his veins in a callous mimicry of sustenance. He thinks he could skip eating forever as long as he got to keep feeling this.But then Jeongmin is right up against him, hard lump of his cock digging into Youmin's thigh, skimming fingers down Youmin's sweaty back. His skin is tacky from the cooling sweat and tentacle slime. Squeezes Youmin's ass harshly, nails digging in, and speaks in a low, gravelly voice. Breathless. Youmin has him breathless."Ask me for help," he demands softly, and Youmin wails again as the tentacle tries to force the giant egg into him and fails, again. So Youmin begs, of course. Babbles out pleas, sucking down thin spit as it garbles his words, makes him sound stupid. And he expects fingers, pushing the egg into him for real this time. Maybe holding him open, making space for it. But instead, Jeongmin grabs his hips and pulls him down, shoving his thick erection up against the egg, grinding against it. Trapped, now, the egg has nowhere to go but in, and it squeezes, bit by bit, into the pounding, soaking heat of Youmin's cunt, and he imagines it's Jeongmin's cock as he clenches around it, forcing it further in. It gets caught at his cervix, of course, but it's not giving so much resistance anymore, and when Jeongmin pulls away from him with a high keening, a veritable flood of eggs slips down into him. The pressure is enough this time, already stuck inside him, and after a long, painful moment and another orgasm (courtesy of Jeongmin's clumsy fingers on his clit), the giant egg squeezes into his womb. Most of the eggs added in have made subtle changes to the weight in Youmin's belly, but this? Youmin swears he feels his skin stretch to accommodate its girth. The eggs shoved up after it drop into him easily; they're not that much smaller, it's just that his cervix hasn't had the chance to close up again.Jeongmin pulls away entirely, hands lingering at Youmin's ass a moment longer, and Youmin pants heavily in the stillness. No more eggs pushing up against him. No more overwhelming stretch of eggs passing through his cervix. And then Jeongmin snaps again, speaks with a dry tongue that sticks to his teeth, and Youmin is hauled back into the chest. The tentacle pulls out and is quickly replaced with a different one, rubbery and a little thicker. What more could they do to him, he wonders? The new tentacle squeezes through his cervix as well, and it starts fucking him in short, strong strokes. He wonders again if maybe the mimic just has a thing for fat tits and wants to watch them jiggle and bounce beneath him. Now, though, his belly is swollen up huge, and his tits brush against the aching skin with each thrust.He's so full he can hardly breathe, his heartbeat pounding in his ears. And it only gets worse as the newest tentacle soon begins to pump what he can only assume is cum into his womb along with the eggs, rounding out his swollen belly. It keeps going until he wails, highest and sharpest yet, and begs it to stop, and only then does it pull out, keeping his head tilted down so the cum can't leak out.And of course, it plugs his cunt too, shoving the warm toy into him and fitting the pointed end into his cervix. It lets go after that, lets the plug settle naturally into place. It's thick and heavy, filling him so wholly he can't help it when he cums again. He hardly has anything left to give at this point, tiny pearls of slick sliding out of him, and he shivers helplessly as the tentacles turn him back upright again.His breathing and heartbeat settle as the mimic starts dressing him up in bondage gear. A harness goes around his neck and chest, framing his full tits between thick leather and metal rings. Some sort of thong is slid up his legs, leather strips pulling between his asscheeks and rising over his hips. More decorative straps go around his thighs. The tentacles make one last pass over his body, tweaking his throbbing nipples, massaging into his swollen tits, pressing in against his heavy stomach until he can feel an egg shoving against his skin. The tip of it slips in beneath the leather covering his cunt, tugging almost playfully at the plug and swirling against his clit before pulling out and rubbing up against him through the thong, harsh enough that he can feel the passes against his clit and moans because of it. It pushes at the plugs in his nipples one last time, tugging on them until they threaten to pull free, and then the mimic is creaking open and presenting him to Jeongmin, finally uncovering his eyes.Some distant part of him thinks to look down at himself, to see what he looks like now that they're through with him, but he sees the way Jeongmin is staring at him and can't look away. Jeongmin is naked down to his boxers, a dark stain in the fabric. Youmin thinks he spots cum dripping down his leg. There's an undeniable hunger in Jeongmin's eyes, and Youmin welcomes it when he steps closer and starts touching him. Calloused fingers roving over sensitive skin pushed to its limit, squeezing his tits together until Youmin moans softly, pressing in against his stomach until the eggs shift inside him. He leans down and takes a nipple into his mouth, sucking harshly, pressing his tongue against the plug shoved into it until it pulls, sharp-bright pain flaring and melting into yet another round of desperate arousal. Maybe it's just the lingering aphrodisiac in his system, but he's never been so goddamned horny.When Jeongmin drops his underwear and ruts up against Youmin's belly, he almost cries from relief. Jeongmin pulls him down after a while, straddling Youmin's body and squeezing his tits together again, fucking in between them. His cock bumps against Youmin's throat, forcing his moans staccato. And when Jeongmin cums, it's all across Youmin's face. He pulls Youmin down to the floor and kneels between his legs, rubbing him through the leather thong until Youmin cries out, arching his back off the ground and shaking through it.Jeongmin is much gentler afterwards, gently toweling Youmin down and settling him into a small, cozy room filled with soft things much like the other half of the last room had been, leaving him alone with a few candles lit and a mirror on the far wall.Youmin crawls over on limbs of lead and kneels in front of the mirror, looking over himself. His nipples are puffy and swollen red, aching softly even as he looks at them. They're plugged up with simple bars, metal balls at the ends to keep them in place. The harnesses are all black, dark against his pale skin. His tits, barely a full handful before, are now filled up, so round and plump that they hang down over the strap of leather running beneath them. When he lifts his hand to fondle one, it's all gushing wetness inside, forcing his tits bigger to accommodate whatever the mimic filled him with. He skates his hands across his stomach, which rests heavily atop his thighs. When he shifts, he can feel the eggs rolling around inside him. His face is stained bright red, and his pussy gives on last pathetic throb-squeeze.Youmin kind of doesn't want to sleep in the bondage gear, but there's no way in hell he's getting it off himself. So instead, he crawls over to the mass of blankets and slips between them, curled up onto his side cupping his stomach and tits.
----- CHAPTER BREAK -----
Youmin doesn't go back into work. He says he's sick something bad and will probably be out for a while. According to Jeongmin, the eggs will take ten days to hatch.Youmin stays at Jeongmin's apartment while he's pregnant. Eggnant? Preggnant. On the sixth or seventh day, because Jeongmin asks and thinks it'll be fun, Youmin lets himself be tied up, arms behind his back and legs held up against his chest. Well, close as he can get them, so not very. His stomach squashes against his thighs. He's in tiny jean shorts and the chest harness and the ropes, and nothing else. Every movement shifts the plug, still lodged in his cervix. The drag of rough denim across his pussy is a little uncomfortable, and an unfortunate turn on. The eggs must be making him horny, he thinks. Jeongmin has to hand-feed him, and Youmin keeps licking him and chasing his fingers as he withdraws.He's kept like that for two days. His stomach swells as the eggs grow larger. Relief and subtle aching rushes through him when Jeongmin finally unties him and draws him a relaxing bath. He wants to ask what happens when the eggs hatch. What they'll be like, what they're supposed to do with the stuff filling his tits. It doesn't really feel like a test anymore. Did Jeongmin do this too?Then Jeongmin reaches into the water and slides his fingers in alongside the plug, and Youmin forgets to ask all his questions.Youmin spends the final morning aching all over, sat down on the couch trying to focus on the TV. Jeongmin is at work, but he'd said that he'd need to feed the baby mimics once they were born. Just pop the plugs out of his tits and guide them a little. They'd figure it out.The notion makes Youmin feel weird, overwhelmed and confused and hot beneath the waistband. He's naked on the couch because his skin is too sensitive now. He keeps his hand pressed to his belly, feeling the little swells of the eggs against his palm. He's not really hungry at all, but maybe it's just that he hasn't got room for anything else by now. He's well and truly stuffed to the brim, and even though Jeongmin was definitely lying to him about some things, he finds himself liking it. He'd do it again. And maybe keep the ring for fun, because he liked the way he felt just after putting it on.As the day winds down, he almost thinks the eggs aren't going to hatch, that it'll happen tomorrow or that Jeongmin was lying about that too. But as the channel switches to a different cooking show, there's a twinge in Youmin's stomach, a little shift inside him, and then a painful cramp. He's quick to push himself to his feet and hobble into the bathroom, closing the door and sinking down onto the tile.Jeongmin had said to go to the bathroom, call him, and wait. Youmin only does one of those things, reaches down between his legs and grasps for the plug. It hurts when he starts to pull it out, instantly throbbing, but he grits his teeth and, a minute later, pops it free and drops it. Cum immediately starts dripping, thick and slow; he spreads his legs and leans back against the door, swallowing hard.Unplugged, the cramping lessens. Everything slows. And tentatively, almost tenderly, something blunt and pointed presses against Youmin's cervix from the inside. Youmin still doesn't know what's inside him. Jeongmin hadn't known. No one really knows what young mimics look like; Youmin will be the first.Searching touches and false starts come before the first real push out of him. A heavy pressure against his cervix, stretching him, stopping up the flow of cum. And after a few moments, it starts to feel like the tentacles inside the mimic, long and thin, burning its way out of him. It's like a fucking Slip 'n Slide inside him as the tentacle wriggles free and plops onto the tile. Reaches down around his belly to grab it, searching blindly until he finds the slimy mass of it. It squirms in his grasp, a dark, purplish-red little thing, searching, seeking. The first of many proto-mimics.There is another touch at his cervix, and Youmin remembers what Jeongmin had said. Feeding. The plug in his left tit tugs gently as he pulls it out, twinging a little but nowhere near as bad as the worm-like mimic trying to shove out of him right now. He drops his hand and lets the plug clatter into the pool of cum gathering against his ass. Slowly, gently, he raises the worm and sets it atop his tits, letting himself slip a little further down the door so it won't slip. He cups himself, squeezing with a kinder touch than he's known for a while, staring in fascination as a thick, purplish goo comes out. The tiny slit in his stiff nipple expands, and out comes the glob and spills down the heavy curve. The worm goes straight for it, squirming and curling around his nipple to get into the mess. Clings using strong muscles as it soaks up the goo.A second worm slips out of him while he's distracted. He pops the second plug free and sets the worm at his other nipple, squeezing more of the purple goo out for it.It gets easier, the more worms come out of him. His cervix stops giving so much resistance, forced loose and wet, and the worms give his body less time to readjust as they start shoving out faster. There's a sweltering throb between his legs because, as it stops hurting, it starts to feel good as the worms leave. Ticklish in a way that makes him feel breathless. Maybe it's the way the worms suckling at his tits circle his nipples and squeeze, massaging the goo out of him in little beads and running strands. Maybe he's just a freak, getting off as he births mimics.Whatever the reason, he finds himself trembling, spreading his legs until they're nearly horizontal. His cunt clenches as a second worm squeezes in alongside the one that'd been trying to get out. He hisses, arching his back off the door, pressing his head against it until he can feel his skull grinding against the wood.When he peels his tear-sticky eyes open, he's met by the sight of his children crowding around his nipples, all searching for food in a purplish writhing mass, like a bruise shifting across his skin. He no longer has to put them on his chest himself, pants another comes free of his womb and starts climbing up his thigh, hauling itself across his deflating stomach to get at the teat. His belly and boobs are both much smaller than they had been, maybe half the size they were in the morning.It's an accident, he thinks. Someone gets impatient waiting for more of the goo to be squeezed out. There's a blunt pressure against his nipple, one of the worms trying to get at the goo, and it thins down. Goes thin enough to dip into the slit. Pushes like it's curious, like it's testing something. And Youmin can't really help it when he gasps, shocked by the pressure, by the sensation of the worm being in him like that. It's not that he wants more of it--he doesn't really know what he wants beyond relief--but he reacts to it the way he does when he has a dick up his ass. He leans into it. Youmin gasps and pushes his chest up, forcing the worm deeper into his fat nipple. There's a moment of stunned stillness, and then the worm wriggles fiercely and shoves into the fat, swollen warmth of him, tumbling against the inside of his tit. He can feel every movement acutely, ticklish to the utmost, like an itch along the bone that he can't reach.It's like the other worms know what their sibling had done. Youmin had expected them to be mindless, but after the first one squeezes back into him, all the rest follow suit. It's a race, seeing who can get inside his tits first. Pushing and shoving at each other, feels like having his nipples fucked, soft and fat and so welcoming. After the first few get in, he starts sucking them in, as if his body is desperate to have them back inside no matter what form that presence takes. His tits start swelling again, filling back up after all his hard work draining them to feed his young.To his credit, he tries to get them to slow. Gasping, he begs them to wait a little, assuring them that there's enough food for everyone and that they don't have to be inside him to get it. But, no. They spare him no mercy, squeezing back into the warmth of his plumping tits with obscene squelches. The purple goo squirts out around each worm that enters him, and those following slurp it up before joining the writhing beds of mimics inside him.Youmin is a sticky, heaving heap. He's so horny he can hardly breathe, heart thudding painfully against his ribs, leadened lungs quivering. His cunt is a throbbing, puffy, soaking mess between his trembling thighs, coated in the mimic's thick, cool cum. Tears gum up his eyes, and the goo from his tits makes his skin tacky, and he keeps drooling because he's moaning so loud and so often he can't shut his mouth.Truthfully, he had forgotten about the giant egg that'd been stuffed into him and the giant worm that would come out of it. So it comes as a surprise, the press of a worm at his cervix that's easily three times larger than all the rest, maybe more. His pussy spasms as he orgasms, drawn far over the limit. The giant worm tugs free and is followed by a flood of cum and worms. Youmin presses the heel of his palm against his nearly-flat stomach and moans softly as more cum gushes out of him. One final worm slips free, and then they're all just rushing to fill his tits to the brim.His nipples are looser by now, so it's easy for the rest of the worms to slip inside him. The biggest, though, crawls sluggishly. It is in no hurry. It will make room for itself if need be; will carve a space for itself within him. Jeongmin said there wouldn't be any permanent changes, but Youmin thinks he was lying. As the giant warm crawls up the heavy, swollen curve of his tit and presses its blunt head into his fat, aching nipple, Youmin knows he's never going to return to his old normal. He understands now, as he watches the worm burrow into his right tit, why so many adventurers end up having to turn to The Sex Dungeon. If he were to tell someone that he was getting off watching his nipple go white with the stretch of a young mimic forcing itself into him... well, they wouldn't exactly be wrong in calling him a freak.He can't look away, though. The worm sinks into him, his fucked-soft flesh forced to open up for it, and with shaking fingers he starts pushing it in. He wants it inside him, faster. It's too slow. He wants it now. It squirms, trying to fight him, but he just stuffs more of it inside, moaning as he rubs against it through his nipple. He draws his knees in, trembling, presses them up against his tits and lets his hand fall away, instead stroking his nipple as the worm squeezes the rest of the way in. It seems like it takes forever, and Youmin cums twice while he watches, caught on a high that blends into one long curl of heat washing through him. And he gets impatient himself, in a vicious mockery of his young, ends up pushing the last inch and a half through, into his bulging tit. The stretched slit of his nipple closes over the end of the worm and falling into a soft peak.Youmin gives himself one last orgasm with clumsy fingers against his clit, squelching through the dripping mess that's been made of his cunt, and then flops back against the door with a soft rattle. He breathes through the aftermath, trying to get a rhythm going so he'll stop panting so hard. He's getting lightheaded. He can't tell if his tits are bigger than they were before, but they feel heavier when he cups them and thumbs across his nipples, which give a valiant effort at getting hard again. The worms settle slowly, writhing around inside his tits as they get comfortable, becoming dead weight as he squeezes gently. It soothes the ache a little, makes the worms shift.When his heartbeat slows and his breath evens out, he hauls himself up and leans against the counter, staring at himself in the mirror. He can see the subtle shifting as his heart thumps, sending tiny ripples through his tits with each rise and fall of his ribs. God, they look huge. He leans forward, hands planted, squashing his tits together and imagining Jeongmin's dick between them. Fucking him. He wonders if Jeongmin is going to be mad he didn't call. He can fuck Youmin's tits and then squeeze the mimics out if he cares that bad.Youmin turns and bends down, freezing up and moaning as his tits fall and jiggle and sway. The worms move inside him, agitated by the jerking movement. Once they settle, he grabs the plugs off the ground and works them back into his fattened, swollen soft nipples, lubed up with cum and slipping into the loose slits.It's fascinating, the ease with which the plugs push back into him. The low current of arousal still thrumming through him is what brings him to pull the one on the right back out and flip it the other way, pushing the larger ball end into the slit and tugging until it grinds against the inside of his nipple. Just big enough it doesn't come out, bulging the tender flesh. He brings up his other hand and grinds his thumb into the bulge. It sparks more pleasure than pain, so he humps uselessly against the counter as he keeps plunging the plug in and out of his fat, hungry nipple. His cunt throbs more and more with every thrust, dripping down the insides of his thighs. Drags his thumbnail up the bulge of the ball beneath his skin, shakes full-bodied as a glob of cum wells up.He rubs his thighs together, grinds against the hard edge of the counter and gets next to nothing out of it, and pulls at the plug until the metal ball peeks out, crowning his nipple. The mimics push at it, trying to free themselves or something, and Youmin jams it back in and grinds the little bulb into the fat bud until he shudders and comes apart, collapsing until his forehead touches the glass.What if Jeongmin came back right now? Found him wanting and open and fucked him against the mirror. Would he even notice that Youmin had given birth without him? Or would he cum into Youmin's gaping uterus and only turn him over afterwards, finding his massive tits and flat stomach. Youmin imagines that he'd get angry, pull Youmin down and squash his tits tight around his cock, so tight it'd hurt, so tight their young would be near to forcing their way back out of him, even with the plugs inside him, stopping him up, trapping them.The front door shuts with a thud, and Jeongmin calls Youmin's name in a bright tone. Good day at work. Well... "In the bathroom," Youmin calls back, keeping his head to the mirror. Jeongmin will probably know what it means immediately. "Was about to take a shower!" He listens to Jeongmin's heavy footsteps and figures they'll see whether his fantasies hold up or not.
