Summary
     The next time Stiles needs to drop something of somewhere he really
     should call ahead first.
Notes
     Thanks to Stilinski-Hale_(padamaa) for lighting a fire under my ass
     to write this :)
     A few things before you read:
     Derek and Peter are still werewolves the rank of Alpha/Beta/Omega for
     their wolf part is different from their designation as Alpha/Beta/
     Omega for their human part.
     Omega's heats can cause an un-mated Alpha to go into rut (what an
     Alpha' heat is called), causing both Omega and Alpha to go into a
     heat haze. Which is why I tagged for rape/non-con.
     The only way to form a mating bond is to have unprotected sex where
     one person knots another.
     Set after 3b, Stiles and Derek are dating and haven't had sex yet.
      
     None of these ficlets in this series go together unless stated.
     Comments are always welcome. Have a great day!

A growl started to build deep in Derek's chest, he's been sitting in Stiles's
Jeep outside of the McCall residence for fifteen minutes. They had only stopped
so Stiles could drop off something for Scott, who apparently would need it upon
his return from dads in a week’s time. Stiles was supposed to be in and out in
two minutes or less, but glancing at his watch it's been sixteen minutes. With
another growl, Derek made his way from the Jeep to the front door, grumbling
along the way about 'idiot boyfriends'. Upon opening the door and stepping
inside Derek froze, the cloying scent of sex and cinnamon invaded his nostrils
and made his stomach roll. He knew that scent, was familiar with it, knew it
meant an omega in heat, he knew it just like he did every time his own heat
cropped up.
After closing his eyes and giving himself a minute catch his equilibrium, he
shakily followed the scent up the stairs, followed it as it grew thicker and
thicker until he stopped at an open bedroom door. Peering in, Derek almost
shifted, Stiles, his mate, was lying on the bed, a very naked and very much
aroused Mrs. McCall was straddling him, her tongue fucking into his mouth and
her hands rubbing something out of sight, while his hands cupped her breasts.
Seconds pass, and what, at first glance, looked to be Stiles participating was
in fact him trying to push her way, albeit gently.
'You need to stop, Melissa,' Stiles said forcefully, 'you are in heat, I can't,
we can't... I... Oh God!'
Stiles words cut short by Melissa finally getting his jeans undone and her
hands around his length. She moaned as his hips bucked him upwards, causing her
hands to slid down his cock and to grip him firmly around his base. A panted
moan left Stiles' mouth and his eyes fluttered open and caught Derek's gaze.
'Oh God, Derek, I'm sorry! Please, I'm so sorry.' Stiles renewed his struggles
to push Melissa off of him, but stopped as she squeezed the base of his cock.
'Fuck, Stiles, I want it, can I have it? Your knot will feel so good inside of
me. Please.' She raised herself over Stiles, trying to line him up with her
slick, red entrance.
Derek roared then and quickly yanked her of his mate. She struggled, legs
kicking and arms swinging, to get herself free, to get back to seating herself
on his mate's cock. Pulling her more firmly to him and away from the bed, Derek
swept his gaze over Stiles's prone form, up his legs to the opening of jeans to
where his thick, long cock stood proudly, a slight bulge starting to form at
the base, and then finally moving upwards he took in Stiles' face, his eyes
glazed over and a healthy flushed covering his cheeks.
A choked sound made it's why out of his chest. Derek had been waiting to finish
the mating process between them, he wanted Stiles to be ready, wanted himself
to be ready and so he made sure nothing sexually had happened between them. In
hindsight it was a stupid decision, he had forgotten that an unmated alpha's
rut could be triggered by a compatible omega's heat, and now he's gotten to
witness it. He gets to watch his mate mount and knot another person, and he
wants to rip his own throat out for waiting to have his mate knot him.
Whining again, Derek looked at his mate's cock for a second time, it hadn't
flagged since Derek ripped Melissa off of him and the sight of it made slick
start to trickle from Derek's hole. He knows that he can't stop them, that once
Stiles' knot ties him to Melissa that he'll lose Stiles forever, he wants to
cry, wants go on a rampage.
Deciding to be the better, he starts to loosen his hold on Melissa, when a
half-formed memory had him tighten his arms around her waist. Peter. Peter had
laughed and told Derek he was being a 'slow poke' and if he was worried about a
bond forming to use one of 'those' condoms, before chucking a small foil square
at his head and leaving with a laugh. Even though he was creeped out he still
put it in his wallet, he can be a responsible adult after all.
Shifting Melissa around to hold her with one arm, he shoved the other into his
back pocket and quickly yanking out his wallet. Derek felt some of the tension
dissolve from his shoulders upon opening and seeing the small square, he'd
rather Stiles not be with anyone else but at least now he won't lose him.
Approaching the bed Derek regretfully shoved Melissa away from himself and
straddled Stiles' thighs, he quickly opened the condom and it rolled it down
his mate's cock, making sure the ring was over the slight swell of the knot.
He wanted to fully undress Stiles, to see him fully but he could hear Melissa's
high pitched whines, so he reluctantly removed himself from Stiles' lap. Derek
was barely an inch away from the bed before Melissa shoved him out of the way
and took up her previous position Stiles' lap. She's sopping wet, slick
dripping down her swollen lips and smearing on her thighs, making them shiny,
and it was easy for her to grab Stiles' cock and slide down it until he was
fully seated inside her. Then she started to move, pushing herself up then
fucking herself down hard onto the cock inside her, each downward thrust was
accompanied by satisfied grunts and pants from both Melissa and Stiles.
Derek had to look away but each grunt and moan, each slap of skin and the
squelching sound of a cock thrusting into a warm, slick hole had him looking
back to the bed. Stiles had his hands clamped around Melissa's waist and he
used them to slam her down on his cock at the same time he thrusted upwards
into her, it was brutal and Derek felt a large wave of slick gushing out of his
hole and drench his boxers. He wanted that, he wanted Stiles to use him like
that, fuck him so hard all he knew was that cock in his ass and those hands on
his waist. As much as this situation was horrible he decided to just go for it,
he stripped himself, clothes and shoes being flung wherever, just so he could
fuck his fingers into his soaked hole.
Derek closed his eyes and leaned himself against a dresser, let the moans and
the wet sounds of sex fill his ears as he fucked two fingers into his waiting
hole, he had barely breached himself when two pleasure filled shouts caught his
attention. While still moving his fingers Derek looked towards the bed, a
boneless Melissa lay sprawled across Stiles, soft whines fell from her lips
every time Stiles' hips made a small hitch upwards.
Derek sniffed the air and whimpered, he could smell Stiles's release and that
coupled with the stillness of two of them he knew they were tied, but a look at
Stiles face had the whimper dying off. Stiles was looking at his ass where
Derek's fingers were still fucking up and into himself, and with a jolt Derek
knew that Stiles had knotted Melissa so quickly because Derek had decided to
get off, and with that thought Derek came, his cum spraying onto his chest and
the dresser he was against. He removed his fingers from his ass, closed his
eyes and slid to the floor, breathing heavily.
A couple of minutes later, or an hour later, Derek really couldn't tell, a
pained noise came from the bed along with the sound of a person falling back
onto the bed, Derek figured the knot had gone down and Melissa had moved
herself off Stiles' lap, he didn't care to look to make sure though, he didn't
want to see her satisfied face.
The scent of fresh cum hit his nose and the splatting sound of an overly full
condom hitting the bottom of a trashcan hit his ears, along with clothes being
removed and thunking unto the floor, causing him to let loose a small whine
which turned into a yelp as he was roughly flipped onto his hands and knees. A
fleeting look over his shoulder showed a very naked Stiles and cursory glance
downward showed a very hard, cum slicked cock.
'Fuck Stiles!' His voice hoarse with the first words he's spoken since entering
the house. 'Fuck, is that for me, baby?' The only response he received was
Stiles pressing closer and the tip of a cock to press against his hole. 'Shit,
okay, go ahead. Please, fuck. I want that, it's mine, I want it!'
Whatever he said was apparently the magic words, for Stiles drove himself into
Derek, bottoming out in one long, smooth thrust. Derek moaned, his cock filling
quickly at the feeling of being so full. Stiles started a pace of fast, deep
thrusts, glancing Derek's prostate with each one. Stiles kept thrusting and
thrusting, muscles tensing and relaxing, sweat dripping off his forehead,
dotting Derek's back. It seemed continuous and never ending, and Derek loves
it, he knows that later he'll crave it, will always crave it, knows that Stiles
will give it to him whenever he asks, and he keens with that knowledge. Derek
wants to cum, he needs to, but he wants Stiles to knot him first, needs it, so
he thinks about anything, why grape candy is purple or why his eyes are hazel.
Moaning from the bed had him opening his eyes to see Melissa kneeling on the
bed, fingers brutally thrusting in and out of her pussy as she watched Stiles
fucking Derek like there was no tomorrow, an entrapped look on her face. Her
eyes became even more glazed over as Stiles picked up the pace, fucking into
Derek faster and faster, slick and cum mixing, adding to the small pool on the
floor every time Stiles pulled his cock out of Derek's loose hole before
punching back in.
A low, guttural moan fell from Stiles' lips as he shoved his cock into Derek as
far it would go and stilling, knotting swelling, pressing at Derek's rim and
tying them together. Derek fell to his elbows, grinding his ass backwards into
Stiles, putting the slightest pressure on his prostate and almost blacked out
with force of his orgasm. Pressing his head to the carpet, Derek let the
endorphins flood his body, the mating bond adding a pleasant sharp bite as it
solidified.
Derek felt fuzzy and buzzed, the only other thing he was aware of was Stiles
shallowly rutting into him, trying to bury his knot further in Derek's ass,
until a soft chuckle had him focusing his attention on the person in the
doorway.
'Well, I must say, when Melissa called me to come over and help her through her
heat I didn't expect this.' Peter chuckled again as he took in the room's
occupants, eyes lingering on Stiles' hips as they hitched forward minutely for
just a few seconds until then moved to the naked, writhing woman on the bed.
'Oh Melissa, has their mating made you delirious with need?' He asked as he
stepped into the room. Stiles gripped Derek protectively; a growl making its
way passed his lips as Peter made his way further into the room. Peter stopped
at the foot of the bed, breathing deeply his eyes flashed blue as he took in
Stiles' scent mixed in with Melissa's previous release.
'I may have to punish Stiles later,' Peter says as shifts himself closer to the
writhing Melissa and hooks his arms under her legs, hands coming to rest at the
swell of her ass. He swiftly pulls her to his chest and picks her up off the
bed, he turns and starts carrying her out of the room, Derek looks up at him as
he passes and watches in horror as Peter opens his pants, pulls out his hard
cock and thrusts roughly up into Melissa. Peter stops just outside the doorway
and glances back at Derek and Stiles and smirks.
'Have fun you two, I know I will,' he says as he winks and lifts Melissa off
his cock and then yanks her harshly back down, causing her to cry out and bury
her head in his neck. Peter tosses a quick 'bye' over his shoulder as makes his
way into the spare bedroom, the slick sounds of him fucking Melissa onto his
cock continues and increases and slightly muffles as the door slams shut.
