****** Lying With Sleeping Wolves ******
by CaliHart
Summary
     Derek never really got a chance to explore Peter's body, so he waited
     until Peter was asleep to get his chance.
Notes
     Pretty much just self indulgent (or Derek indulgent) Halecest porn.
Peter was sound asleep when Derek crept into his room at night. Peter had drank
copious amounts of wolfsbane-laced liquor to celebrate his birthday. Derek had
watched as bottle after bottle emptied into his uncle’s throat and licked his
lips in anticipation. Derek had gone to bed first and slept for a few hours so
that he wouldn’t be too tired later. He woke up when Peter stumbled up the
stairs and down the hall to his room, and Derek listened until everyone else
was asleep before getting up and sneaking down the hallway.
Peter was lying on top of the sheets on his bed, the blankets kicked away in
his sleep and his limbs flung out. Derek took a deep breath and held it, his
cock giving a twitch as he noticed he could see the outline of Peter’s cock
through his boxers, which were the only thing he was wearing. He made sure the
door was closed and locked behind him before walking quietly over to the bed.
He licked his lips as he leaned over and slowly, carefully pulled Peter’s
boxers down over his hips, letting out a tiny moan when his soft cock was
bared, and he had to stop and stare for a moment. Peter’s cock was bigger than
Derek’s own by an inch or two, the skin pinkish and smooth. The hair around the
base was neatly trimmed. Derek couldn’t see his balls with his thighs close
together and his cock laying over them, but he knew that they were shaved bare.
Peter was particular about his personal grooming.
Derek continued pulling Peter’s boxers off and tossed them to the side before
shedding his own loose sleep pants and t-shirt. When he was as naked as his
uncle, he carefully spread Peter’s legs and knelt on the bed between them.
Derek was already half hard from the anticipation alone, but he didn’t want to
rush things, which was the point of coming in when Peter was asleep. What Derek
really wanted was to take time to explore his uncle’s body thoroughly, but
Peter was always too impatient, rushing through the few trysts they’d had and
not letting Derek linger when he touched him in the shower. Times like this
were his only chance.
Derek reached out and trailed his fingertips over Peter’s foreskin first,
feeling the softness and the way it slid over the head when he pushed on it
lightly. He traced his fingers all over it, from the bottom of the head to
where the edges met over the tip. He spent several minutes on it, then he
gently pushed the foreskin down past the head, watching as the slightly redder
skin was revealed. Derek couldn’t resist the urge to lean down touch the tip of
his tongue to the slit. He could feel the warmth and taste the salty tang of
Peter’s skin, and he had to stifle a moan. He licked the head a few times and
gave it a sucking kiss before pulling back, not wanting Peter to get hard yet.
His own cock twitched as he rubbed the back of his hand across his mouth to get
rid of the drool.
Next he took Peter’s soft length in his hand, cradling it and rubbing his thumb
against the silky smooth skin. He liked the way it looked and smelled either
soft or hard, and he leaned down to rub his nose against it. Derek had a
fantasy about rubbing Peter’s hard cock over every inch of his body. He’d let
it fuck into his mouth, trace the tip all over his own cock, have Peter fuck it
against his nipples and balls, let it leak into his hair. He wanted to be
coated in Peter’s scent. He’d offer to suck on Peter’s balls in return. Peter
always came really fast and really loud when he did that. But Derek hadn’t been
able to work up the courage to ask for it.
Peter’s cock was starting to plump up and harden by the time Derek moved down
to the base. He played carefully with the loose skin there, moving it up and
down and gently pinching it between his fingers. During puberty male werewolves
grew the extra skin there to make room for their knots to expand when they
finally developed fully. Derek had only seen Peter’s once, when he’d nearly
knotted Derek in the shower but Derek had slipped at the last second and
Peter’s knot swelled outside of him, too large to push back in. Derek had
dropped to his knees in apology, wrapping his hands around the knot while Peter
leaned back against the wall. He was in awe at how big it was and how much come
Peter produced. Derek watched as spurt after spurt landed on his chest and
trickled down his body until he was practically coated in it, a bunch of it
collecting on his aching erection. He’d even directed some of it onto his neck
and face, curiously licking it off his lips. Peter’s eyes had flashed and he’d
dragged Derek up to push his face into his neck, inhaling their mixed scents
while he smeared his come on Derek’s thinner body and humped against his
smaller cock. They’d both had to sit on the shower floor to recover for a long
time afterwards.
Derek leaned down to rub his tongue against that loose skin until Peter’s cock
twitched against his face. He carefully retrieved Peter’s lube, slicked up a
few fingers, and lay down between Peter’s legs before reaching back to open
himself up. He took the head of Peter’s half hard cock in his mouth, sucking
lightly and playing with his foreskin with tongue and teeth. Derek started
bobbing his head after a few moments, the foreskin moving with his lips, then
released his cock to duck his head and lick at his balls, holding back a giggle
at the way they bounced slightly from the force of his tongue. Peter moaned
softly above him, and Derek froze and stared at his face, but Peter didn’t move
and his heartbeat stayed sleep-slow, so Derek relaxed and continued working his
fingers inside himself. He nuzzled Peter’s balls, then licked his thighs for a
change of pace and worried the skin to leave small but matching hickeys on each
thigh. His cock twitched against the bed at the thought of Peter walking around
wearing his marks, and he had to suck on Peter’s length to keep from moaning.
He encouraged it to full hardness with his mouth, then had to stop and rest his
head on Peter’s hip while he focused on fingering himself open, adding more
lube to make sure he was wet enough. He gave Peter’s cock a few more sucking
kisses when he was ready, and then he sat up.
Derek cautiously moved his legs over Peter’s until he was straddling his hips,
then he reached back and guided Peter’s hard cock to his wet hole. He bit his
lip to muffle his groan as he sank down, Peter’s cock throbbing against his rim
and filling him up in a way nothing else did. He had to stop for a minute to
catch his breath when it was all the way in, his ass flush against Peter’s
hips. Then he started out with slow rolls of his hips, enjoying the slide of it
against his rim and reluctant to let more than an inch pull out of him. Derek
sped up gradually over several minutes, basking in the feeling of having his
uncle’s cock hard and probably leaking inside him while Peter himself was
asleep. Derek had to pause at the thought of Peter’s fluid inside him, face
flushed and teeth buried in his lower lip as he rubbed his hands over himself,
imagining they were Peter’s hands. He gasped as he pinched his own nipples and
sparks traveled through him, precome drooling out onto Peter’s abs and making
them sticky. He clenched down and lifted himself up slowly, whimpering at the
sweet slide of Peter’s cock dragging against his tight muscles.
He couldn’t help himself after that, bracing his hands on the bed and working
himself up to a fast ride, practically bouncing on Peter’s cock. He was
panting, his eyes closed, when he felt Peter’s cock start to catch on his rim
each time it pulled out. Derek gasped and reached back, fumbling fingers
circling Peter’s cock and feeling his knot grow. Derek bounced a few more
times, keeping his fingertips on the knot to monitor it, then plunged down onto
it when it was big enough, moaning as it swelled and locked inside him. He
jerked his head down when he felt hands on his hips, seeing Peter blinking
blearily up at him.
“Derek?” Peter asked sleepily. Derek gasped and threw his head back, his vision
whiting out as he came, whimpering, barely registering Peter’s groan. He felt
thumbs rubbing against his hips when his senses started to work again, taking
another minute to open his eyes. Peter’s chest was streaked with his come, and
he was looking up at Derek with sleepy blue eyes. He gave him a soft smile when
he saw Derek looking at him.
“Hey. Why didn’t you wake me up?” he asked softly, his fingertips pressing into
Derek’s asscheeks as his thumbs kept rubbing his hips.
“Didn’t want to,” Derek replied, sounding wrecked. “Wanted to see if I could
get you to come in your sleep. Wanted to watch you sleep while your knot filled
my greedy hole.” Peter groaned and Derek gave a small grin of triumph. Peter
liked when Derek occasionally talked dirty to him.
“But I didn’t get to see you,” Peter protested. Derek leaned forward and kissed
him softly.
“Go to sleep, Uncle Peter. I’ll still be here in the morning, you can see me
then.” Peter grumbled but nuzzled Derek’s face, wrapping an arm around his
shoulders to keep him close. The alcohol that was still in Peter’s body wore
him out fast, and soon he was asleep again. Derek used a corner of the sheet to
wipe his come off Peter’s chest so it wouldn’t dry there, and then he cuddled
up to him, squeezing around the knot to feel the pressure of it. He fell asleep
smiling into Peter’s shoulder.
