Summary
     Stiles tilts his head at Peter. “You gonna be alright with him?”
     Peter looks at the doorway to the guest room a long minute and then
     nods. “I've known him his entire life. I can handle teenaged Derek.”

     Prompt: Halecest, younger Derek gets overwhelmed by hormones and just
     pounces on Peter
See the end of the work for more notes
Derek is settled carefully on the bed in Peter's spare room, the pack gathering
in the living room, while Lydia stays by the bedside holding his hand.
“Is he in a coma or something?”
“I”m guessing his body is simply overextended, due to the sheer amount of
change.” Peter paces a bit, while Stiles scribbles this down on the back of an
envelope. “I'm not sure how she did it, but Kate took Derek back to a time
before the fire, a time that he trusted her.”
“Derek knew Kate?” Scott's brows arch.
Peter can't believe this idiot boy is his Alpha sometimes. “Biblically.”
Scott wrinkles up his nose. “Ew. She's old.”
Peter sighs internally. “Our biggest problem right now is that Derek had some
serious control issues at this age. None of the humans are safe around him.
I'll stay with him tonight, but in the morning you'll have to come get him
Scott. As his Alpha, you're the only one who can control him.”
Scott nods and goes to get Lydia.
Stiles tilts his head at Peter. “You gonna be alright with him?”
Peter looks at the doorway to the guest room a long minute and then nods. “I've
known him his entire life. I can handle teenaged Derek.”
He wants the rest of the Pack away before Derek wakes up. The boy's going to
have a lot of questions, but he's also going to expect certain things from his
uncle. There's no way Peter is telling any of this ragtag pack that he and
Derek had been having a physical relationship when the kid was this age the
first time 'round.
Scott ushers the other teenagers out the front door, turns back at the last
minute. “Call me if you need anything.”
Peter nods. “We'll be fine.”
He shuts and locks the door behind them, and goes to make some food. No doubt
Derek will be hungry when he gets up.
He's just rising from putting a lasagna in the oven when he feels a body
suddenly plastered against his back.
“Derek...” He starts to turn around, but the arms that slide around him are
like bands of iron. Peter doesn't remember Derek being this strong. Then again,
he hasn't been exactly up to strength since coming back from the dead.
“Derek, we've got to talk, there are some things-” He's cut off as his solar
plexus hits the counter, and all the breath gets knocked out of him. By the
time Peter can breathe again, he can feel Derek rutting up against his now
perfectly placed ass.
“Derek, stop it.” He's annoyed but not surprised. He had a feeling that
something like this might happen when the unstable werewolf caught his scent.
Peter pushes up from the counter suddenly, overbalancing his nephew, who takes
a step backwards. That's all that Peter needs and he ducks down and twists,
extricating himself from the grasp of the younger, stronger man.
“Derek, snap out of it.” Peter puts as much command as he can into his voice as
he eyes the boy across from him. Derek is completely feral, eyes glowing blue
and shifted into his beta form.
And he's damned quick.
He's right up against Peter again before the older man can even react, and it's
not until Derek shoves his nose into Peter's neck that he realizes. “Hm, I
don't smell right, do I Derek? I don't smell like our pack. Or even like you
anymore.”
He reaches up and strokes his nephew's hair gently, holding him tightly,
thinking that the close quarters will settle the instincts down. As soon as he
smells like Derek enough, maybe he will snap out of this.
Turns out it's not enough, because Derek's rubbing against Peter's thigh, and
he's definitely already hard.
Peter closes his eyes. He's pretty certain that if he doesn't assist this
along, that it's going to happen in spite of him. And contrary to popular
belief, Peter Hale is not into pain.
“Alright, Derek, c'mon, lets not do this in the kitchen. The bedroom would be
so much more comfortable, don't you think? Derek.” He sighs and pulls his neck
away, reaches and tilts Derek's chin up. “Bed.”
The glowing blue eyes blink once and something must get through because Peter
finds himself hoisted over Derek's shoulder. “Dammit, I can walk. I'm not going
anywhere.” Peter is really glad that no one can see him right now.
The older man is unceremoniously flopped onto the bed, and Derek is on top of
him, smothering him with his body. Peter shifts and then freezes at the warning
growl from the feral wolf, brain actively ticking over his options.
He's distracted from that by claws shredding through his clothing, hissing as
Derek catches skin.
“Gently, Derek, no need for that-” Peter is cut off as lips are crushed against
his, fangs slicing into the soft tissue. He tastes blood as Derek pushes his
tongue into Peter's mouth, whimpering against the boy's mouth as the claws
slice deep again.
Peter lifts his hands, extending his own claws, and thinking that he can maybe
bring Derek back to human, he rakes them down the boy's side.
It's a severe miscalculation.
Derek pulls back and roars, then sinks his fangs down into his uncle's
shoulder. Peter jerks beneath his nephew and uses all his strength to shove him
to the side. He catches Derek by surprise, and just manages to reach his
bedside table, grasping a small bottle from the drawer before he is tugged back
into place.
The rags of his clothing are pulled away, and then Peter feels the rasp of
Derek's tongue sliding soothingly along the slowly closing wounds. He hopes it
will keep the boy busy for a few moments.
Hurriedly, Peter slicks up his fingers and reaches around himself, wincing as
he pushes two digits inside right away. He has no idea how long he has before
Derek really jumps him, and though he'd heal eventually, Peter would prefer not
to tear in the first place.
Turns out he has all of two minutes.
He's just gotten the tip of the third finger in, when Derek tires of laving his
tongue along Peter's torso, and flips the older man. Peter has no idea when
Derek slid free from the pajama pants he'd been wearing, but there's nothing
but heated skin pressing against him, pushing him down into the bed-covers.
And then Derek's nosing into his neck, clawed hands reaching around his
shoulders to hold him in place. Peter feels the blunt head of Derek's cock
slide across his still-tight entrance twice before it catches, and even with
the hasty preparation, it still burns with the stretch.
“Slow down, Derek, easy,” he manages to gasp out, hoping that something in his
nephew can hear him. Maybe there is, because the next thrust is slower, and as
Derek slides all the way home inside his uncle and holds himself there a long
moment, his hands are somewhat gentler as they skate along Peter's torso.
Peter can't help but gasp and arch up as a thumb slides across his nipple, and
Derek notices, of course he does, because he doesn't leave them alone for a
long time, first stroking, and then rolling and pinching.
By the time Derek finally leaves them alone, they're puffy and sore, and he can
feel it every time they brush across the fabric beneath him. And when the boy
shifts position, frantic thrusting finally hitting that sweet spot, it's enough
for Peter to harden, dick fattening where its pressed between his body and the
quilt.
Derek rumbles approvingly above him when Peter rolls his hips to get some
friction, and starts fucking his uncle harder and faster. Peter slides his cock
along the bed, but it's not until one of Derek's claws catches on his nipple
that he comes, cries muffled into the soft fabric of the comforter.
Derek fucks him right through his orgasm, hips snapping forward with
supernatural speed, and then his claws dig into Peter's ribs, fanged teeth
biting down hard at the nape of his neck. The boy makes a muffled howl against
Peter's skin, and then the older man feels the hot pulsing inside of him of
Derek filling his uncle with his seed.
He closes his eyes and presses his forehead against his arm as Derek pulls
away, slides out. Peter can't help the whimper as he turns on his side. Even
with his healing, that will hurt for a while.
He looks at Derek, who is passed out once again, and thankfully human once
more.
Peter doesn't have the energy to move right now, so he's still in the same
position on his side, a half hour later, when hazel eyes flutter open, confused
gaze taking in his uncle.
“Peter?”
“Shh, Derek, it's going to be alright.” He slides an arm out and tugs Derek
close, wrapping his arms around his nephew. “Everything's going to be okay.”
