Chapter Text
Stiles has been friends with Derek for a long time. So by the time they’re sixteen he had spent a lot of time at the Hale house.
Coming across Peter in just his boxers on the couch watching tv wasn’t exactly a shock. Derek’s parents are out of town for business, and they took little Cora with them. Laura is already at college, and Peter is a senior this year.
The weed is a slight surprise.
“Don’t you have other things to do?” Peter breathes out, and smoke plumes out with the words. “Like bug Derek?”
“He has basketball, but dad’s not home tonight so I’m waiting until Derek gets back.”
Peter hums and turns lazy eyes back to the screen. A few strands of hair hang down in front of his forehead, heavy with sweat from the heat.
“Hey, Peter?”
“If you’re about to ask what I think you are, no.”
“Aw, please?” Stiles whines. He’s only had a few experiences with pot, but so far he’s enjoyed them all.
Peter glances over at him considering. “What would you do for it? Jamie once put on his sister’s panties for a joint.”
Stiles cheeks flush. “You want me to... to put on panties for a joint?”
“I want to amuse myself. You want weed.” Peter shrugs and takes another lazy drag. “Laura’s room is upstairs.”
“Peter.” Stiles cheeks are on fire.
“Suit yourself. Some people have the balls, some don’t. More weed for me. And Jamie, I suppose.”
Peter goes back to watching the tv. After a quiet moment, Stiles speaks up again. “A whole joint?”
Peter grins like the Cheshire Cat. “A whole joint.”
“God, you’re a weirdo.” Stiles huffs, but turned to go upstairs.
Laura’s room is organized, and her underwear drawer easy to find. Unfortunately, there are no simple pairs. There are laces and strings in all different colors, all of them revealing.
Stiles feels his face heat up again, but if Jamie, one of the coolest guys Peter’s friends with, can do it, so can Stiles.
He goes for one of the “tamer” pairs in her collection. They’re a jewel blue that stands out against his pale skin like a bruise, but they don’t have the mesh material in the front that a lot of them have. They cover his cock, although the bow on the front is still rather embarrassing. The back is non-existent; only a string that goes between his butt cheeks and no other material.
It’s uncomfortable at first because he’s not used to having something rub there, but he wiggles around some and that will have to be good enough.
His only problem is that it’s so hot he’s slightly sweaty, and if a pair of Laura’s underwear magically turns up in the dirty laundry it might seem suspicious.
“Can I at least wear pants over them?” He calls down.
“No, just the little girl panties.” Asshole.
Stiles takes a deep breath in before awkwardly making for the stairs that will take him to his doom. He carries his clothes with him and puts them on the back of a chair so he can change as soon as possible.
He shifts uncomfortably in the entryway of the living room. “Now can I?”
“Yeah, but you have to stay like that. Since I’m wearing my underwear, too, and all.” Peter drawls gleefully and shifts so that his body is angled more toward Stiles.
Stiles flushed a deep red again, probably looking like an American flag combined with the panties, and goes to stand in front of the couch Peter’s sitting on.
“Here,” Peter says, and hands him his reward. It doesn’t take long for Stiles to light it and take a few drags. After just a couple he’s feeling floaty. He really should try building a tolerance some time.
“How’s that?” Peter asks, wiping his forehead from sweat again.
Stiles just nods, unable to express how good. Give him a minute.
Peter chuckles. “Why don’t you sit down?” He grabs Stiles hips before he can even react and pulls him down onto his lap.
Stiles can feel Peter’s bulge right there. Right between his not-at-all covered cheeks.
“Um, Peter,” Stiles starts to ask.
“It’s fine, take another hit if you want.”
Stiles isn’t going to pass up the opportunity. He did follow through with his end, after all, so why not? He sees Peter pick up the remote control but then he’s taking another and he doesn’t care.
When Stiles can focus again, it’s because Peter’s hips are hitching. His hips are hitching, his dick is gliding through the sweat in Stiles crack and maybe his own precome, and there is porn on the screen.
The smaller boy on screen is on his back with a dick at least twice the size of his own buried in him.
“Why is that...” Stiles trails off, waving his hand in the direction of the tv but it feels light like helium and doesn’t stay there long.
“Guys watch porn together all the time, Stiles.”
“I- okay.” Stiles feels unsure but tries to relax.
Peter’s hips start hitching upwards again and again, and Stiles can’t help but rock slightly into the motion.
“Sit up a little,” Peter says, patting Stiles’ ass. Stiles raises up without thinking and feels a pull, not realizing it’s the feeling of material leaving. As soon as Peter has his panties pulled down out of the way, his greased up cock is back between Stiles’ cheeks, shifting so it bumps his ass hole.
After a moment Stiles realized the reason he can feel it is because the string barrier is gone.
“Wait, Peter,” but Peter is already pulling Stiles down by the grip on his hips. Stiles can feel Peter’s damp cockhead pushing against his hole, huge and straining to get it. “No, no-“ and the head pops in. A yelp falls from Stiles’ mouth as Peter let’s out a heavy groan. Peter looks down at where Stiles’ rim is pink and stretching. He shifts and the boy on top of him shudders.
“Peter, you have to take it out. God, it’s big, I can’t.” Stiles pleads, heavy hands reaching to grab Peter’s hands on his hips. His pot-heavy arms knock Peter’s hands away from his body alright, but he can’t quite hold himself up, so when Peter lets go he has no place to go except down.
Stiles let’s out a high pitched whine as he slides further down Peter’s hard cock. It feels massive. He still hasn’t even seen it bare, but it has to be, God, he can’t even think of how big it must be. His mind is trying to drift away and also focus.
“Oh, God, Peter. Peter, you have to. I can feel it all the way inside me. Peter you have to take your dick out of my ass.”
“You feel so good, sweetheart. So amazing.” Peter slurs. “Just relax.”
The heat seems to increase, now Peter’s sweaty chest against Stiles’ sweaty back. Both of their foreheads slightly damp. It’s unlike anything Stiles thought he would be experiencing today. His dick was still soft from the stretch and because he wanted Peter out.
Peter grips Stiles’ hips again and drags him up off his dick, making Stiles pant slightly. After a few moments of nothing but the video still playing on tv and anticipation, Peter thrusts up.
“Oh, jesus! Don’t do that, it feels weird, Peter.” Peter only moans at the clenching of the younger teenager’s ass. He picks up the pace, thrust after thrust smacking against Stiles.
He wraps his arms around Stiles’ waist and pulls him back into each slapping thrust. Stiles jerks and let’s out a hoarse shout when Peter hits something that feels intense, but not necessarily in a bad way.
His best friend’s uncle speeds up, thrusting even harder, and Stiles’ dick is filling up from the battering to his prostate. “Oh, God,” Stiles gasps out. “It feels like you’re- it feels like.”
“What’s it feel like, sweetheart?” Peter asks against his throat. “Does it feel good?”
“It feels like you’re jerking me off,” Stiles’ toes curl and he cries out as Peter pauses to grind up into his prostate. “B-but there isn’t anything touching my dick, ah!”
“That’s cause you were made for this,” Peter rumbles, biting Stiles nape just to hear the noises he makes. “You were made to be my pretty little whore. Were made for pretty panties and my big cock in your pussy, weren’t you, sweetheart?”
Stiles starts shaking his head back and forth with a sob. His face is flaming now, his entire chest feels warm with humiliation. “No no no.”
Peter coos at him. “It’s okay, baby. We both know you were, you don’t have to deny it. Don’t you feel how amazing it is to have just my cock in your hungry hole, baby girl? You don’t even need me to touch your clit.”
“I’m not. I’m not a g-girl,” Stiles sobs. He was still hard. “I don’t want this.”
Peter pulls Stiles flush to his pelvis and stops, pulling a stuttered groan from him. “You don’t? Weren’t you just telling me it feels good? And look at your little clit, it’s all hard. Looks so beautiful all swollen in those panties. You even picked out a pair with a bow, such a good girl.”
Peter grabs his- his. “Your clit, right? You want me to play with your clit?”
“Peter, Peter please,” Stiles cries as he thrashes, pinned on the senior’s dick. “Feel so hot, I need to come.”
“Tell me what you want me to do and I’ll let you.” Peter lightly grinds up to stimulate Stiles again.
“Ah! I- fuck me! Please, just fuck me,” Stiles pants, grappling for purchase on Peter’s thighs. He’s still facing the tv where the top is trying to put his hand in the twink’s hole, now.
“That’s not how good girls ask,” Peter tuts.
Stiles whines. “I can’t.”
Peter reached up and pinches the boy’s nipples. He plucks then and Stiles sounds like he chokes. “I’ll just have to play with your little tits until you can.”
Stiles started shifting and gasping at every rough squeeze, pinch, pull and pluck. Peter just smiled. “So sensitive.”
“I want you t-to fuck my,” Stiles takes a sobbing gasp. “My pussy.”
Peter fucks up once and the boy on his lap howls. “And?”
“A-and play with my, ah, my little clit.”
“Perfect,” Peter soothes, thrusting again lightly. “My perfect baby girl, you did so good.”
As Peter develops a rhythm again Stiles’ mouth falls open. He can’t even make sounds, it feels so overwhelming. Peter grabs his clit again, stroking fast with a firm grip.
Stiles can’t take anymore, he’s been strung out too long, and he comes with a shout. His entire body tightened up and Peter groans, only getting in a few more thrusts before he comes.
When Peter comes down from his orgasm, he notices Stiles spacing on the couch. Now or never.
He grabs the younger boy and carries him upstairs to Peter’s room. He sets Stiles on the bed, still dazed and staring at the ceiling, and makes quick work of cleaning the come off of him with wet wipes.
Reaching toward his bedside table has his body growing hot again and his cock valiantly attempting to grow hard again.
It takes a few minutes to make it work but it helps that the boy is soft. When he’s done, there’s a bubblegum pink cock cage fitted on Stiles, and at the moment he’s none the wiser.
Little does he know, he’ll be wearing this always from now on.
