Chapter Text
Stiles was a good kid. He never misbehaved, or acted up. Sure, his grades weren't exactly the best, but he tried his hardest, and according to his father, that's all that mattered. So when his best friend Scott suggested they got fake ID's to go to clubs and bars, he was reluctant - but with some extra pushing from Scott, here he was, standing in a bustling night club full of drunk twenty-somethings, standing awkwardly at the bar and watching Scott go crazy on the dance floor.
He wished he'd never come. He usually liked parties, but today, something felt off. This club had a different aura, something tense and strange and different. He looked over at the opposite end of the bar, and caught eyes with someone. A man, maybe mid twenties. He had piercing blue eyes that shot right into his, almost leaving him stunned. The man shuffled on his seat slightly, and he came into a heavier light, and Stiles could see him clearer. He was jaw-droppingly handsome - a chiselled jawline with a short, shaved beard and nicely styled black hair.
Now, Stiles wasn't one to consider himself gay or something, but he'd always had male crushes since he was young. Daniel Radcliffe when he first saw the Harry Potter movies or older movie stars as he grew up, and this man was exactly Stiles' type. After some painfully torturous eye contact, the man got up. Stiles froze. What was he meant to do? The man was just approaching him, so suddenly, and he was just meant to sit there and let it happen, brewing in his own sweat and panic?
It was too late to think anymore as the man sat down on the bar stool next to him. Stiles got a smell of the man - musky, he smelt a little unsanitary but maybe that was just the club. It wasn't exactly the cleanest. He just looked at the man, who gave him a little smile, his teeth were pearly white and he had small dimples in each side of his cheek. "All alone, huh?" The guy spoke, tilting his head. He had a deep, gritty voice that made a shiver run down Stiles' back. "It's okay, me too. I'm Derek, Let's get you a drink."
The man ordered them a beer each, and kept charming Stiles the whole night. They talked about school, and what Derek did for work - he was a hunter, apparently - and an hour later, Scott had disappeared with some girl he was getting on with and left Stiles alone, completely in the hands of Derek who promised Scott he would look after him. They were on their third beer now, so Stiles found himself needing to pee more and more throughout the night - but he was having such a good time with Derek, there was barely a place to break their conversations off.
"Hey, I'm just going to pee. I'll be right back," Stiles smiled gently, and Derek just nodded back and gestured towards the toilet as Stiles got up and scurried away. He reached into his pocket, and pulled out a little silver vial, filled with some luckily beer-colored liquid. He swiftly threw it into Stiles' drink, mixing it in with a little swirl of the glass, and carrying on like nothing had happened. Derek had selected his target, the perfect little boy for all his dirty perverted dreams.
When Stiles came back and took a little sip from his glass, Derek couldn't help but break a smile as Stiles started to feel dizzy and his head began to spin. He just put a hand firmly on Stiles' shoulder as the younger boy seemed to spin out, his head going fuzzy and his vision going blurry.
"It's okay, Stiles..." Derek cooed, pulling him closer and stroking his head, letting the boy go completely limp in his arms. "That's alright, we'll take you home okay?..." He whispered, giving the side of his head a quick peck. "That's a good boy... go to sleep. We're going to take great care of you. My perfect little boy."
-
When Stiles woke up, he was completely disoriented. He was hit with a bright light as his eyes fluttered open, and he felt his back on ice cold metal. He took a minute for his eyes to adjust as he looked up, seeing a dark-skinned man above him, doing medical checks on his body as he heard the subtle beep of a ECG that was monitoring his vitals.
"Dr. Deaton, I think he is waking up." He heard a muffled voice say, a voice that was eerily familiar to him.
"Stiles? You're going to feel a little strange for a few moments okay? Now, this will only hurt a bit..." The doctor whispered, and Stiles felt a prick of a needle going right into his arm. It seemed to speed up the healing process, and within a few moments, Stiles was awake and fully responsive.
Once he gathered his surroundings, he looked around the room. On a chair next to the bed sat Derek, with a soft smile on his face, stroking Stiles' arm. "It's okay, baby, don't panic." He whispered gently, and Stiles got a shiver again - this time, he wasn't attracted. He was simply terrified.
He looked down as Deaton walked around to the hospital gown that was covering him, and tugged the gown down to his sides. He practically felt his heart drop.
Gone was his penis the thing that he knew for so long - and in replacement, a new, fresh, tight pussy was on his body. Stiles felt his breath quicken, and his head fogged with questions. But more importantly, where the hell had his dick gone? Now he had to admit, it wasn't the biggest thing in the world, but he didn't exactly want it to just disappear, and he definitely didn't want it replaced with a vagina. But here he was, laying flat on cold metal, looking down at his new pussy in absolute terror.
He whined in fear, looking at Derek as tears slowly rolled down his cheeks. "Wh-what have you done to me?" Stiles spoke, but Derek shushed him immediately. "No, no... babies don't talk Stiles."
He watched as Derek got up, and shoved a light pink pacifier into his mouth. "Now suck on your pacifier and be a good boy. You're my little son now, okay?" He whispered, pressing a gentle kiss to his forehead. Stiles was disgusted, completely distraught that he was being degraded like this. That he was a complete mess, whining on a metal table as he sucked on a pacifier, crossing his legs to cover his little tight pussy that he was so embarrassed of.
"Now, let's go home, son."
-
The nursery was every child's dream. The walls were light pink and light blue, and a nice white Stiles-sized crib laid in the corner by the window, that had been sealed shut. There were clouds painted on the walls and a little mobile above the crib, which Derek laid Stiles in as he gave his forehead another quick kiss. "Good boy, do you like your new home Stiles? It's nice isn't it." He looked down at the boy, who had been crying for half an hour straight, all the way home. Derek just took a long, hard look at his new boy, completely naked in his crib. "Now, lets get you changed into a diaper."
A diaper? Hell no, Stiles was barely managing from his new pussy and his pacifier, which he was still chewing on. There was no way he was pissing and shitting in a diaper. But he didn't have much choice - he'd tried kicking and screaming for help when Derek tried to take him home but Derek was too strong - he could easily grip Stiles shut, so he just let the man pull him out and shove him down on the little changing table.
Derek traced a finger along Stiles' pussy, which made the little boy tremble and whine. "It's good work, isn't it Stiles? A real, working pussy and a womb and ovaries to get you pregnant." He whispered, looking up at the boy who just whimpered and shook his head. "No, baby, agree with Daddy or I will have to punish you for being a bad boy." He warned.
Punish him? Derek was already too attached to him, Stiles thought, what's the worst he could do? So Stiles just kept disagreeing - shaking his head and grunting in disapproval. But Derek had planned this. He wanted Stiles to misbehave, he wanted to punish the boy, just to show him what it was like. "No? You're going to keep disagreeing, aren't you baby Stiles. Alright then. I warned you."
Derek rolled Stiles over onto his chest, and rubbed a firm hand over his perfect huge butt. "Naughty boys get spankings." He whispered. He lifted his hand up, and spanked Stiles, hard. Hard enough to earn a cry from the boy. Another spank, and then one on each cheek. Stiles cried out in pain, even letting the pacifier drop out of his mouth onto the floor so his cries could become louder and louder, but Derek only longed more, just watching his boy scream and cry made him the happiest man on the planet.
A solid ten minutes of pure spanking later, Stiles' ass was ripe and red, burning from the heat of the slaps. "It's okay, Stiles, you can cry. Bad boys cry when they misbehave, don't they?" He whispered, Stiles just cried even more as his butt was abused. Once Derek was satisfied with Stiles' red ass, he flipped him over, this time focusing on his pussy. It was brand new and shiny, perfect for some spanking there, too.
"Now this will hurt a bit more." Derek warned, leaning down to kiss Stiles' head again, as the little boy kept crying and crying in pain. He started slapping his pussy - not entering his insides, just spanking and slapping his pussy and doing it in spots that made Stiles cry even harder. "That's it, your little pussy hates this doesn't it?" Derek grinned sickly.
Eventually, Derek finished spanking Stiles' pussy when it got a little too red and sore. He laid Stiles down and grabbed some baby oil, rubbing it over his pussy to soothe it a little and then doing the same for his rosy ass. "Good boy. All done." He whispered. He then reached under the table and pulled out a pack of diapers, opening it and grabbing a fresh one. "This one's for you Stiles." He smiled as he gently attatched the diaper to him, wrapping his baby boy up in it and smiling proudly. "Now any poo-poo or pee-pee goes in here, okay?" He said. "The more that's in there in the morning, the bigger the surprise I will give you."
Once he was done punishing Stiles, he was brought back to his crib and laid the boy into it nicely. "That's what a punishment is like, Stiles. And every time you misbehave it'll get worse and worse until you stop misbehaving? Okay, baby? I don't like to hurt you but if you act up then I have to. Just do what I say and don't let me hurt you again." Derek planted a kiss on Stiles' cheek gently, and shoved the pacifier back into Stiles' mouth.
Stiles had just finished crying for the second time today - getting his ass and pussy spanked was an awful experience and to be honest, just shutting up and doing what Derek said sounded much better than ever having to go through that again. So he went along with it.
"I'm going to make your dinner, baby Stiles. We have a big day tomorrow. I'm going to teach you all the things we'll be doing okay?" He smiled, ruffling Stiles' hair and giving him a nod before leaving the room, hearing the lock click from the outside.
This was Stiles' chance. He climbed out of the crib - sure, it was big enough to fit him but that didn't stop him from just standing up and getting out. He walked over to the window on his tip toes, careful not to step on a creaky floorboard or something as he tried the window - sealed shut, with tempered glass. There was no way he could smash that or open it. Next, he tried the door. He heard Derek lock it, but maybe that was just to stop him from opening it? Unfortunately that didn't work either, he really was trapped inside.
He just trudged back to his crib, sitting up in it and just hoping and praying he'd at least get some proper decent food. He thought maybe an hour had gone by before he heard footsteps coming up the stairs again, but who knew? He had no concept of time besides seeing how light it was outside. It could've been five minutes or five hours.
Derek walked back into the room without anything, and instead walked over to Stiles in his crib with a proud smile. "Thank you for not running away, Stiles." He whispered. "Daddy appreciates it." He lifted Stiles out of the bed, and carried him in his arms like a bride down the stairs. "We have something very nice for dinner okay?"
As they walked into the kitchen together, there was a small dining table - on one side a normal chair for Derek, but for Stiles he had a white high chair with straps and a little plastic plate. Derek had a big meal in front of him, chicken, rice and broccoli with a beer on the side, and Stiles had a tiny portion - a couple scoops of rice, a few bits of chicken and a whole heap of broccoli. "It's important for babies to get their greens in." He whispered, strapping Stiles into the chair.
Stiles sighed at the meal in front of him - he wasn't going to complain, it was still food - and he learnt he had to agree with Derek on everything or he was punished. But what made things worse was when Derek brought a baby bottle over filled up with warm milk. He was being treated completely like a newborn and he felt totally grossed out.
"Drink up, baby. You have to get all that calcium if you want to grow up and be a nice strong boy." He smiled and ruffled Stiles' hair, giving him the bottle with the little nib on the top that he had to suck on. Stiles whined - like he wasn't already grown. This dude was just mentally ill and trying to live out some disturbed fantasy.
After Stiles had finished his meal, he looked up at Derek with a gulp as he was tucked into his crib. "Now, baby. I'm going to be just across the hall," Derek whispered in that soothing tone. "I can hear everything, even the slightest tip-toe. So don't try to escape, okay?" He whispered, giving his forehead a kiss. "I'll see you in the morning. Get some good sleep... tomorrow is going to be a big day full of lots of fun."
-
When Derek had woken Stiles up that morning, Stiles wasn't sure where he was. But when he adjusted his glare, he realised he wasn't in the crib anymore - he was on top of the changing table with Derek waiting there for him. "Good morning, baby." He whispered, stroking Stiles' hair.
It wasn't a nightmare, Stiles thought. He really was still here.
Derek gently pulled his diaper off, and sure enough, it was full with some nice deep brown shit and smelt of piss. "Baby did well, didn't he? Look at all the mess you made." Derek showed Stiles the diaper, and Stiles went bright red. He didn't even notice, it must have slipped out of him in the night. And god, it was truly humiliating.
Derek brought the diaper to his face, taking a good long smell of Stiles' shit and letting out a soft hum of happiness. "You did really well, baby boy." He grinned and threw the dirty diaper away in the trash can beside the changing table. He turned Stiles onto his back, and saw his red sore ass from yesterday's events, and spread his cheeks. Sure enough, the insides of his cheeks were stained a dirty brown from when he must have shit in his sleep.
"You have a dirty little hole, Stiles. And since you did a good shit for me in the night, I'll happily clean you up."
Stiles widened his eyes. He was already totally weirded out by Derek smelling his shit, but cleaning him? That didn't sound normal, there wasn't any cleaning wipes near - but when he felt a wet, warm muscle hit his ass, he let out a big moan. Derek was licking his shitty ass clean.
Derek explored and tasted all of the shit, licking it all up and moaning at the sweet taste of his baby's waste. He discovered every inch of Stiles' slightly hairy, smelly hole, and cleaned up all his poo-poo while he did. He pulled up after a few minutes, shit all over his mouth. "That's it, baby boy. All clean." He said in the most satisfied, happy voice as he sat Stiles up again. He leaned in, and kissed Stiles' lips, getting some of the rank-smelling shit into Stiles' mouth.
Stiles winced at the taste, god, it was horrible and made him gag and feel sick. He couldn't believe it - the baby still was enough, but now Derek was sniffing his shit, and eating it?
Stiles just gagged, holding his throat as he was forced to swallow his shit. Derek frowned, stroking Stiles' face. "No gagging, baby. Your shit is beautiful, you should want to eat it." He whispered, pecking Stiles' forehead. "And when I'm done with you, you will want to. It's time for me to introduce you to your new favourite thing." He smiled.
He picked up Stiles, and brought him inside the bathroom. He sat him on the edge of the bath, and smiled. "Are you ready baby? You're about to see something amazing." He whispered excitedly. Derek took his shirt off slowly. His chest was muscled and very hairy, it was clear the man didn't shave at all. Stiles gulped, the man was beautiful. His body was Stiles' dream.
Derek then moved to his shorts, they were black tight basketball shorts that he just pulled down to reveal matching black boxers. He had a huge, thick bulge and just from that, Stiles knew he was big. He was expecting to have to just get on his knees and suck the guy off for hours on end, but as he anticipated that, he was totally taken aback when Derek turned around, facing the wall, and took down his boxers.
He had a huge, thick, hairy ass, and he wanted to use Stiles to pleasure himself. He leaned over the counter, ass directly in Stiles' face, about six inches away from him. He smiled and spread his cheeks, and sure enough, it was just as hairy as the outside. "Now, Stiles." Derek spoke, in a deeper, darker voice, with a sadistic grin on his face. "Part of your job being my baby, is that you're also going to be my human toilet."
The words made Stiles want to gag and throw up.
"A human toilet, resulted to just letting yourself take my farts, my shit, my piss, my vomit. Whatever I give you, you take it like a good boy. Like the dirty shit slut you are. Now, you can choose to fight it. To try to run away. But if I catch you... you'll get a punishment ten times as worse as the one you were given yesterday. So shut up, stop crying, and put your fucking face in my ass."
Derek spoke with such terrifying words that Stiles couldn't even cry. He wanted to, he wanted to scream his lungs out and fight his way out of all of this, but fuck. He just couldn't. His Daddy terrified him. So he just did what he was asked, and moved his head forward, his face on Derek's hole. Derek let go of his cheeks, bent over the counter as his butt completely covered Stiles' face.
"Sniff."
At that point, Derek let out a loud, disgusting, smelly fart, that made Stiles cough and wretch. But he didn't move his head back, he just let the hot stench engulf him, swallowing the fart.
"Good boy."
Another fart came from Derek's stinky ass, an extremely loud one that made Stiles wretch even more. Derek loved the noises, his baby boy gagging for his repulsive farts.
Stiles must've been there for at least fifteen minutes, just taking Derek's farts like a good baby boy should. When Derek pulled back, he looked at Stiles. Tearstains on his face, a bright red blush, completely destroyed by Daddy's farts.
"Get in the bath. On your back. Mouth open." Daddy ordered.
Stiles did exactly as he was asked, and laid on his back in the bath reluctantly. Derek got in the tub after, just squatting over Stiles' face. They were there for a little while, so Derek could build up a big shit in his ass and position his hole right over Stiles' mouth. Derek hadn't taken a shit in a few days to prepare for this moment, he'd fantasised about it ever since he was a teenager and now it was finally, finally, coming true.
A long, thick log of shit slowly came dripping out of Derek's smelly hairy hole, and fell directly into Stiles' mouth. The feeling and the smell of the rancid poop made Stiles gag and cough, but there wasn't much he could do apart from swallow and chew the shit like the good boy he was for Derek.
Derek kept the shit coming, moving his ass a little so it dropped on Stiles' face, in his hair, on his neck and the top of his chest. By the time Derek was done a few minutes later, Stiles was a full shitty mess, just crying silently underneath the piles and piles of smelly shit he'd been buried in.
Derek took the chance to stand up and get out of the bath, just looking at the mess he had created, his new baby boy in the bath, farts all over his skin and shit all over his face. It made his heart happy. He positioned his soft cock over Stiles' face, and after a few moments, he was pissing on top of all the shit, letting it seep down onto Stiles' skin, going in his mouth and mixing with Derek's mess.
When Derek had done peeing, his cock slowly started to grow hard at just looking at the boy on his back in the bath - all the way from his spanked little pussy to his smelly face, he adored the kid so much, his new baby boy, his new shit slave, his new fuckhole.
He slowly got in the bath again, this time getting them both into a missionary position on the floor of the tub. He started by shoving a huge wad of shit into Stiles' mouth, which made the boy wretch under him, gagging uncontrollably.
"That's okay, baby boy. You know how much I love you for taking my shit like such a good baby? You're doing so well, Stiles, my perfect slutty Stiles." He mumbled as he rubbed the pre-cum emitting from his tip over Stiles' outer lips, which made the boy's virgin pussy start to grow wet and he started to whimper and moan with all the shit and piss in his mouth.
Derek just kept teasing his tip over the outside of his pussy, letting it grow wetter and wetter, letting him squirm and get teased to the point where he wasn't just crying because he got dumped on, but because despite how much he hated Derek and everything he'd done to him, he wanted to get fucked. Hard.
Derek swirled his fingers over to Stiles' clit, laughing menacingly as he started to pinch it and flick it with his fingers, letting Stiles' pussy juice coat his fingers. Derek smiled happily, pushing his two fingers into Stiles, which made the boy scream out with pleasure. He started scissoring his fingers back and forth, curling them inside Stiles' cunt, making the virgin twitch and cry.
After a few painful minutes of torturous teasing, Derek pulled his fingers out. With his non-coated hand, he pushed all the remaining shit into Stiles' mouth and down his throat so he could see his beautiful boy's face again. "Good boy, are you ready for me to fuck your pretty little cunt?"
To Derek's surprise, Stiles nodded desperately. The little overworked boy couldn't take any more teasing, he wanted to get fucked as hard as Derek could take him, and Derek definitely wasn't going to oppose. He pushed his tip into Stiles' cunt, letting out a soft moan himself as he started to slide more of his cock easily into the vagina, Stiles was tight as hell but he was easy to slide into because of the genuine amount of wetness his pussy had leaked.
Before he knew it, Derek was mercilessly pounding into Stiles' cunt, slamming his hips into Stiles' thighs, making the boy below him whine like a little puppy and cry like the baby he was. Derek loved it, seeing the boy's mouth wide open, shit filling the insides, piss on his face, getting fucked like the dirty little toilet boy he was.
Stiles let out a surprisingly loud hitched moan when Derek started flicking his clit too, rubbing it with his fingertips as he spent a while slamming into him and working on his little overstimulated clit. Within a few minutes, he heard Stiles moans get louder and quicker, and before he could tell what was happening, Stiles had squirted out of his cunt and all over Derek's cock and crotch, only making the noises wetter and the fucking more pleasureful.
Derek brutally fucked into Stiles for twenty minutes non-stop, just wrecking that virgin cunt of his and opening up his insides. When Derek finally came, he pinched down on Stiles' clit with one hand, coaxing another orgasm out of the boy before he shot his thick ropes of semen deep into Stiles' cunt.
Stiles' vision blurred, stars peppering his vision as he was cummed in, his little pussy getting filled to the brim with his Daddy's cum. He numbly chewed on the shit and let the piss drip down his throat as he leaned back, completely overwhelmed by what had happened to him.
-
When Stiles next woke up, it was from the harsh cold temperature of the shower hitting his face. He started to stir and mumble, before realising he was still laid down in the bath, but he was being cleaned. It took a few moments but the water slowly turned warm, heating him up and making him less cold. Derek kneeled beside the bath, whispering sweet nothings into his ear as he cleaned all the shit and piss off of him, and for some reason, Stiles drew to it.
He'd been through so much these past two days, so much abuse and pain and horrifying experiences that it felt nice to have a warm hand sliding across his face, making his skin smooth and he leaned into Derek's touch. He heard an approving hum from Derek as he kept his eyes shut, nuzzling against his hand.
"I think this might be working quicker than I imagined, baby."
