Summary
     Unrepentant knotting porn.
Isaac wakes a little when Derek comes in—the rumble of the loft's sliding door
is impossible to sleep through—but the change in air pressure carries Derek's
scent to him and he relaxes, tucking his head deep in the pocket of his arm and
sliding easily back into sleep, soothed by the contentment of Derek's home.
He wakes again when Derek peels the sheet back and slides in, big hand curling
over Isaac's side, pulling Isaac back until his hips frame Isaac's ass. "I want
you," Derek whispers hot into Isaac's ear, rutting his dick—already hard—into
Isaac's crack.
Every time Derek murmurs those words it sends the same tingling rush through
Isaac's chest and belly and down, cock and nuts, fattening him up before he's
even fully conscious. Inside, he feels heavy and then soft, a tickle as he
starts to flow.
"I want to knot you," Derek says, thicker, slurring the words as he bites his
way along Isaac's shoulder, sharp pinpricks of his teeth.
"Yes," Isaac groans, because Derek always needs that, that explicit yes. Isaac
arches back into that heavy dick, letting it split him wider, expose his hole,
Derek's shaft rubbing against it and getting his leaking slick all over. He's
always wet for Derek, an embarrassing gush that he's always afraid everyone can
smell.
The first time Derek fucked him was the night Boyd and Erica left, though Isaac
has wanted Derek—cock or knot or whatever—pretty much from the time he pushed
off the earth-mover and saved Isaac from the fresh-dug grave. The choice to
become a werewolf seemed like a simple one, self-evident, and he'd much rather
be an omega in Derek's pack than one in his father's house.
Even now that Derek's fucking him, he never makes Isaac feel like he was born
wrong or that there's something wrong with him for turning out an omega, never
once has cursed him out as weak or useless and if he calls Isaac a slut, it's
always—always—preceded by the word 'my'.
It matters, that 'my'.
He misses Boyd and Erica, but he knows if they'd stayed, he'd never have this,
Derek would've never done this.
It's only because it's the two of them.
"Isaac…" Derek's fingers push at his hole, spreading his slick up and down and
around his crack before shoving in, three of them. Isaac muffles the moan that
stutters from his lips against his forearm, flexing into it, the rough spread.
It hurts, but Derek has taught him: pain isn't something to be afraid of. It
fades, heals, like the tooth gashes he leaves in his arm, biting as Derek
finger-fucks him hard and deep and slow, opens him up to take Derek's cock,
Derek's knot.
God, he hates that he's glad they're gone, but he is, he is, because he wants
this, he wants it so much… He licks at the drool surging over his bottom lip,
sucking it back.
Derek's tongue tastes a wet trail between Isaac's shoulder blades before his
teeth skim Isaac's nape. It's not a bite—not yet—but it twists Isaac's spine
anyway, belly dropping low, hips canting high. "Derek," he gasps, because it's
not enough, he's itching inside, cramping, and fingers aren't enough, he needs
more. "I'm ready. I'm ready, just mount me," he groans, undulating with the
rhythm Derek forces on him, "just mount me, fuck me, please...oh, ohhh…"
Isaac's face drops to the mattress, his forehead grinding against the sheet as
Derek fills him. One steady thrust, not brutal, but definitely inevitable.
Colors throb against Isaac's sealed eyes, his own private fireworks, set to a
soundtrack of his greedy, guttural moans.
"Good," Derek slurs, mouth open hotly over Isaac's nape as he works in, "so
good." His fingers stroke down Isaac's side until they lodge on his hip to grip
tight, molding to the bone. "Take it. Milk it."
He doesn't have to tell Isaac; his inner muscles tug and suckle at Derek
desperately, instinctively, begging for the thick crush of his shaft over
Isaac's prostate, needing to have him deeper still, in the soft, swollen, itchy
space that marks him as omega.
Why did you even bother choosing to be a boy?
Isaac's father had been a firm believer in the philosophy (debunked! Decades
ago, debunked, dammit!) that any omega 'tendencies' Isaac had in him could go
away, if Isaac would just toughen up. But Isaac's always known what he is, a
growl in his stomach like hunger around every Alpha he sees. Around Derek.
Derek sheathes home with a deep, pistoning thrust that slides Isaac up the
sheets. Isaac grabs at the headboard, locking his elbows, dropping his weight
into his spread knees against the press of Derek's body against his. Derek's
knot isn't up yet, but the base is dense, unyielding, spreading Isaac's rim,
rubbing across the sensitive muscle.
"Good," Derek slurs, barely a word, sensed mostly in the radiance of his
approval, warm in Derek's scent, filling Isaac's nostrils. "So good. Open up
for me."
Isaac's still oozing with slick, wet noises with each push into him. It tickles
in his hair as it trickles, thick trails down his balls, the inside of his
thighs. Derek knuckles it from Isaac's skin and smears it over Isaac's bottom
lip.
Isaac opens his mouth and callused skin slides over his tongue, bringing the
sharp-sweet taste of his own wetness.
"Suck," Derek tells him, "lick it clean."
Isaac's cock hurts with the need to come but, at the same time, he wants to
ride this edge, being taken and waiting, wanting and needing.
They're not going anywhere with this, Isaac knows that. Sometimes Derek wants
him. Sometimes, Derek even needs him, needs someone who'll do what he's told.
Isaac can be that for him, for everything that Derek is for Isaac.
It works.
Derek pins Isaac's shoulder, using them for greater leverage to drive into
Isaac, each meaty thud of their bodies meeting like an earthquake.
"Good little omega," Derek croons, tracing down Isaac's side to tuck his
fingers into the crook of Isaac's hip, jerk him up and back and yesssss, that's
where Isaac needs Derek, like a squeeze to the balls and his dick and
scratching an itch all at the same time. "My little omega. Going to breed you
up, someday."
Isaac didn't think he was that close, but the barest suggestion, that Derek
could, that Derek would, makes Isaac's balls convulse hot and tight. Isaac
buries his face in the pillow, muffling his shouts as he comes hard, load
emptying into the sheets.
Derek grunts like he's the one that came and surges up, spreading Isaac's legs
even wider with his knees and pounding into Isaac with a ferocity that shakes
Isaac to the bones. The press against Isaac's rim is constant, now; the ache as
Derek's knot swells, the continual tingle of those nerves as the knot massages
across them, rippling into and merging with the pulses of his orgasm,
amplifying it and extending it until it's radiating out through his whole body.
"That's it," Derek noses at Isaac's hairline, breathing hot against his
sensitized nape in time with the whimpers leaking from Isaac's mouth. "Let go.
Let it all go. Sweet. So sweet."
The first time Derek fucked him, Isaac cried, overtaken by emotions he still
can't explain, other than relief. It'd been his first heat not fucked up on
suppressants—which never really stop a heat, just make it not a public
nuisance—his first heat not locked up and alone, with only his own inadequate
fingers to work with.
Just being touched, solid against his feverish skin, had been overwhelming.
Derek hadn't even knotted him then, just doing his duty, easing Isaac through
it, but being fucked—by anyone, but especially Derek—it was everything, it was
too much. More than he deserves.
Isaac keeps waiting, but it hasn't stopped feeling like that.
Derek's knot slips finally and completely past Isaac's rim, locking them. Isaac
groans, toes curling and his pelvic muscles squeezing tight around that
delicious, hard, knot.
"Isaac—" Derek inhales sharply.
"Yeah," Isaac agrees shamelessly, still muffled by the pillow. He flexes over
the knot again and then again, as much for how it feels as to encourage Derek.
Derek gives a punched out grunt, followed by a high, oddly boyish whine as he
comes. The first surge aches hotly, a new kind of stretch as Derek's balls jet
the first, high-volume streams into Isaac's channel. It sits right on that line
of pleasure and pain, cramps and slow, building warmth as Derek's come soothes
that desperate inside itch.
Eyes closed, Isaac writhes slow and easy on Derek's knot, feeling it, milking
it, lip caught tight between his teeth.
"Isaac," Derek says again, softer, gentler. His hands are gentler, too,
smoothing down Isaac's sides with just his finger and nail tips. Derek's nose
traces a line between Isaac's shoulder blades, seared by his breath as it
eases.
It's been a while since Derek last fucked him; Derek's knot is big and tight,
his cock still spitting its first, heavy load into Isaac. They're going to be
tied a long time and Isaac wants to reach back, see if he's even holding all of
it in.
"Did you mean it?" Isaac would swear he wasn't even thinking about it, the
question seems to come out of nowhere, rise out of him like a giant burp after
too much Pepsi, but it's too late to call it back. "About…?"
Derek gets very still and Isaac makes a small noise and body hitch of protest.
"Would you want that?" Derek asks slowly, resuming the lazy corkscrew of his
hips.
"Do you?" Truth be told, Isaac hasn't thought about it a lot. He knows he's
supposed to be hard-wired to want kids, an omega, but he's still his father's
son. What kind of parent could he realistically be?
"Isaac." Derek sighs, hands spanning Isaac's hips and pulling as he sits back
on his heels, bringing Isaac with him. Isaac lets out a shuddering sigh as the
change in position reseats Derek's knot against his prostate and Derek's
cockhead against his o-spot.
"Fuck," Isaac hisses, unable to reassemble his thoughts for long moments as
Derek forces him into a sharp arch. Isaac slings one arm around Derek's neck to
hold himself there as Derek thrusts up into him again with renewed interest.
Isaac probably won't be able to come up with any more jizz tonight, but he's
starting to tingle with dry orgasm, one valiant, clear bead building in the
slit of his dick.
"So knot-hungry," Derek gloats against Isaac's nape and Isaac moans in
agreement. "Always so desperate for my cock."
Locked together like this, Isaac can't really ride Derek, only wind his hips
and rock. Which is plenty good for Isaac, but maybe not enough for Derek when,
after only a minute or so, conversation forgotten, he shoves Isaac back onto
his knees.
Isaac fumbles for a grip on the headboard again, breathing harsh through his
open mouth and sparks flying like falling stars through his body as Derek bobs
his knot back and forth inside, so deep inside.
"You gonna let me put a pup in you?" The question is guttural, like Derek can
barely grit it out. Balancing on one hand, he spans the other across Isaac's
quivering stomach. "Let everyone know I put my come all up in you?"
Heat and cold flash across Isaac's skin and his head bends, dizzy, on his neck.
"Yes." It comes out nearly soundless, just a hiss of the s. Isaac groans,
pleasure, frustration, then tries again. "Yes."
If he would be a terrible parent, he'd be one with Derek. Derek, who took him
in, Derek who made him strong, who trusts him, relies on him, needs him—an
omega.
"For you," Isaac stammers, caught between admitting the truth and the orgasm
building up huge and perfect in his balls. "For you, I would."
Teeth sink into Isaac's shoulder, sharp, sudden—a wolf's teeth—and Derek comes
in him again, hot, jetting flood, making Isaac ache, making him snarl and
writhe for it until his own soft dick twitches, orgasm washing through him like
the tide against the rocks.
It doesn't feel like Derek's knot's deflated at all, but he's heavy and loose-
limbed after two orgasms, bringing them both over onto their sides, his arms
tangled around Isaac like he's afraid Isaac could somehow get away.
They sleep like this most nights, even when Derek doesn't fuck him. They
haven't said anything about it, either of them, and Isaac hasn't told anyone,
even Scott. It's not a secret, not like the stuff with his dad. It's
just…private.
Derek's tongue laps lazily at the closing skin of Isaac's shoulder, at his
neck; his fingers trace shapes low on Isaac's belly and Isaac feels sticky
where Derek's knot stuffs him full. He doesn't want to sleep, holding onto
this, but he might not have a choice about it, tiredness creeping in and
weighting him down.
"You have to finish school," Derek murmurs, barely loud enough for even Isaac's
hearing. He presses briefly into Isaac's stomach and Isaac feels it, sweet and
almost-itchy, caught between Derek's fingers and the swollen pressure of
Derek's knot. "But then… If you want…
"I would. For you, I would."
