Summary
     Stiles is working himself over when he receives an unexpected
     visitor.
Notes
     So, a plot bunny bit me while I was sitting in class and, well,
     needless to say, I fic'd again. =) Shameless Derek/Stiles because
     it's another OTP of mine and I'd yet to do a fic with them as the
     primary pairing. So, here it is!
See the end of the work for more notes
Stiles muffled his frustrated groan into his pillow, breathing raggedly through
his nose.
He was naked in his darkened room, face down on his bed with two of his fingers
buried as deep in his ass as he could get them.
It wasn’t enough. It wasn’t anywhere near enough and it made Stiles want to
cry, needing to be filled.
His cock was aching and full, leaking as he fruitlessly humped the bed, the
friction of the sheets teasing him. His other hand was under the pillow,
clutching at it in a desperate attempt to ground himself, trying not scream as
completion danced away from his reach.
He’d been at this for so long, stretching himself out, sliding his fingers in
and out, fast then slow. His wrist was killing him, but he couldn’t stop, he
had to keep going, he needed to keep going, needed to fall off the edge of his
pent up frustration until he crashed into sweet oblivion.
But he couldn’t. Get. Deep. Enough.
Stiles shoved his fingers in punishingly hard, chastising his uncooperative
body.
 He froze when he heard a sound at his window.
No, not at his window, it was his window, the sound of the glass sheet being
slid up slowly and carefully from the outside. Someone outside was opening his
window quiet as they could, and all Stiles could do was freeze, his hand jammed
deep in his ass and his heart in his throat.
The only ones with the dexterity to get to his window from the outside were
werewolves.
Quickly he flashed through his not so extensive list of possible intruders.
Couldn’t be Scott, he’d have called if it was important. It couldn’t be
Jackson, he didn’t give enough of a damn about Stiles to track him down in his
own home. The same went for Isaac, really, and Erica and Boyd had left.
Peter, now, he was creepy enough for it, but there wasn’t anything worth
threatening Stiles for that the other wolves couldn’t get for him.
Which left Derek. Who already had a history of helping himself into Stiles’s
room. Who had a habit of physically proving his dominance over the gangly teen
in ways that made lonely nights that much more unbearable. Who could probably
force his dominance over him right now and Stiles would be helpless against
him.
Stiles’s cock hardened impossibly further at the thought as it wept onto the
sheets.
There was a soft thud, easily missed if Stiles hadn’t been listening for it,
tightly wound as he was.
Stiles’s ass reflexively clenched down on his slick fingers, forcing them out a
fraction.
In the quiet of the room, Stiles’s harsh breathing was deafening, despite his
attempts to even them out through his nose. There was no way that Derek could
possibly misinterpret what Stiles was doing. His back was bare, exposed to the
room, and his legs were obscenely spread apart, showing off his slick,
stretched hole, wrapped tight around his own fingers.
He lay there waiting, hard as a rock with his ass on display, but there was
nothing, no further sounds that indicated another person was in the room,
watching Stiles finger himself and listening to the quick palpitations of his
heart.
Stiles whimpered as need overrode his self-consciousness. Once again, he began
sliding his digits in and out of his grasping hole, rocking his hips into the
bed.
Lust-addled as he was, the naughtiness of having someone watching him like
this, spread out and vulnerable, spurred him on, making him moan a little
louder, thrust a little harder, thankful beyond words that his father was out
the overnight shift tonight.
A dip of the mattress startled Stiles.
His fingers would have slid out altogether had it not been for the strong hand
wrapped around his aching wrist, driving his fingers back in, deeper than
Stiles could manage on his own.  
A strangled moan left Stiles’s throat as he mindlessly pushed back, grinding
himself onto his own hand as Derek’s shifted it roughly back and forth, setting
a driving pace that made Stiles nuzzle his head into the pillow.
The sound of Derek’s zipper being pulled down torturously slow made Stiles’s
ass clench in anticipation and his mouth went dry from the need to be filled.
He swallowed roughly, trying to moisten his tongue through his uneven panting.
The bed jostled as Derek moved around.
A sharp snap of the lube bottle being opened had Stiles’s full attention.
 Derek tugged on his wrist, gently pulling Stiles’s hand out of his ass, only
to liberally coat it with lube, making sure to wet his palm. The action
confused Stiles until he felt his hand being folded around Derek’s cock, thick
and hard and hot in his slick hand. He couldn’t see the member but, fuck, it
felt gorgeous and Stiles licked his lips, wanting a taste.
Again, Derek directed Stiles’s movements by his wrist, using Stiles’s hand to
glide up and down, spreading the liquid from root to tip. Taking the
initiative, Stiles squeezed the turgid cock, his grip awkward from the
uncomfortable twist of his arm, but it was easy to ignore his discomfort if
Derek made that sound again, a deep throaty growl from within his chest.
Thoroughly slicked up, Derek pulled Stiles’s hand away and positioned Stiles up
onto his knees, his ass in the air and his head down on the mattress. Stiles
wrapped his arms around the pillow, uncaring about the mess he was getting all
over it. He had a feeling he’d need to wash more than his pillow come morning
and he twisted the lumpy pillow in anticipation.
Something hard and thick was at his entrance and there it was, Derek’s cock
pressing slowly in, letting Stiles get used to the unfamiliar feeling of being
split open on someone’s dick.
It was overwhelming, hot pressure slipping inch by inch into his bowels. He
panted, feeling cold sweat break out across his skin, trembling beneath the
weight of Derek and his long, thick cock. He felt like a bug, pinned in place
and helpless. Derek petted Stiles’s back and flanks, soothing the tremors
wracking Stiles’s body as he tried not to clench down on the unyielding length.
Finally, Derek bottomed out, his heavy balls against the curve Stiles’s ass.
A large hand reached around to fondle Stiles’s flagging dick, teasing it back
to hardness and effectively distracting Stiles from the pain of being so
stretched.
Little by little, Stiles’s whimpers of hurt turned into moans of pleasure,
rocking forward into Derek’s grip then back onto his cock.
It started slowly, a gentle push forward and back, Derek letting Stiles fuck
himself at leisure until slow wasn’t enough. Stiles needed to speed up, needed
the friction in him, on him, and so he pushed up onto his elbows, rocking
faster, hands fisting in the sheets for leverage. It felt good, controlling the
pace, but it was still there, that desire for more, deeper, harder and Stiles
was already at the limits of what his body could do.
He whined in frustration.
“Derek, please.”
That was all the other man needed.
His hand released Stiles’s dick, prompting a whine of loss from the teen.
Firmly gripping Stiles’s narrow hips, he pulled out a few inches and slammed
back in, driving a groan of relief from Stiles’s throat.
Finally.
Stiles tilted his head back and just took what Derek gave him, letting the man
drive in and out, pulling Stiles back onto his cock.
Derek pulled a hand off Stiles’s hip to grip his neck, urging Stiles down until
the side of his face was pressed to the mattress, keeping him down with a hand
around his nape and growlingas he pounded into Stiles’s slick hole.
The sounds forced out of Stiles were high pitched and broken, bursting out of
him under the relentless drive of Derek’s cock. It was bliss, being used for
Derek’s pleasure, losing himself in the slick-slide of in and out, deeper and
faster, just this side of being too much.
His mind was wonderfully blank in a way Stiles could only achieve with the most
back-bending of orgasms and Derek was creating it without a single stroke over
his weeping erection, which hung heavy and forgotten as Derek fucked sparks
into his eyes.
Every other thrust brushed against his prostate, pulling wretched mewls from
him that he’d normally be ashamed of, but his pride had fled, followed by doubt
and fear and every other conscious thought in his head.
There was only Derek’s cock, pounding into him, making his toes curl and forget
his fucking name.
Something snapped in Stiles, like a rubber band pulled too tight, and then he
was coming, clenching hard around Derek, still moving inside him, fucking him
through it. After the roaring left his ears, Stiles stopped clawing at the bed,
his muscles going limp as his body was completely tapped out.
Derek released a rough, animalistic snarl before pushing in viciously, dragging
Stiles back onto him by the grip on his neck and holding him still, rolling his
hips in tight, uncontrolled movements as he spilled his come inside Stiles’s
relaxed hole.
For a few minutes, there was nothing but the sound of heavy breathing, Stiles
boneless in an awkward heap on the bed with Derek still buried within him.
Eventually, Derek eased out and Stiles winced at the soreness, semen oozing out
of his hole in a warm trickle.
Stiles collapsed onto the bed as Derek finally let go of his hips, content to
simply bask in the residual tingles of his best orgasm to date.
He felt Derek pull his cheeks apart, exposing his slack and abused hole. The
flick of tongue against his sore pucker drew a whimper from Stiles as he lay
prone on the bed. His breath hitched, overloaded as Derek licked and delved
into his hole, tasting the mixed flavors of Stiles and himself.
Derek sunk blunt, human teeth into the back of Stiles’s neck, bruising the skin
there, marking him. Stiles held still, heart beating hard from having Derek’s
dangerous teeth on him as much as from his recent exertion.
He felt Derek pull away and roll off the bed. There was a grind of a zipper
being pulled up followed by the quiet shutting of his window before Stiles
found the energy to turn over.
Derek was gone, as though he’d never stole into Stiles’s room and made him
quake under his touch.
After wiping up the mess with a discarded shirt, Stiles flopped back onto his
bed, smiling and wondering if leaving his window open in the future would lead
to more earthshattering nights like this.
