It was pretty damn annoying being woken up by your arousal. It was even worse to know that by day five, Stiles was used to it.
He didn't hesitate to roll over and press his body along the side of Derek's, the werewolf still asleep on his back. He writhed against him, hard cock rubbing against his thigh, smearing precome all over his skin.
"Dereeek," he whined, nuzzling his nose into the guy's neck and scratching at his torso with blunt nails.
The Alpha slowly woke up with a groan, still half-asleep when he looked down at the younger man. Dark circles now lay under his eyes, hair a ruffled mess, beard untrimmed and untidied. He looked rough, like he hadn't gotten much sleep over the past few days but had still been busy putting his body through a lot of physical motions.
Which really, he had been.
A wave of guilt washed over Stiles at the knowledge that he'd done that to Derek, that he was responsible for his sleepy, messy state, that he had it worse because he'd been the one pounding and thrusting and knotting, while Stiles just had to lay there and take it. Hell, the Omega could fall asleep while being knotted, get a few extra minutes of shut eye that way. He wasn't entirely sure if the same went for the older man, considering the mini-orgasms and tremors that wracked his body while knotting someone.
The thought of Derek's knot had his arousal kicking guilt in the face and shoving it aside, reminding Stiles that it was the most important thing at that moment. He mentally apologized to the Alpha and promised himself to get him a nice gift, maybe take him out to dinner or something.
His hips rolled against the other man's side, grinding into him, a fresh spurt of slick leaking out his gaping hole. Thanks to his arousal and the number of times he'd been fucked over the past couple days, it was still open, unable to fully close. Convenient, but also weird as hell, especially considering the lack of sheet covering them—no point since Stiles still felt like he was running at about five hundred degrees, a nice change from the thousand he was at yesterday, and they were just gonna have sex again anyway so the sheet would keep constantly getting in the way—and the cool air hitting his insides.
Weird as hell.
Derek liked his lips, lids halfway down his eyes in fatigue. But despite his mental tiredness, his body was fully awake, instincts picking up on the Omega's fake fertile scent and driving him with the overpowering need to mate and breed, causing his body to get ready for it, even if he wasn't entirely awake or ready for it.
"Again?" he croaked out, voice rough from sex and sleep and not enough sleep.
Stiles felt his guilt come creeping back, a background emotion to the arousal currently running the show and controlling his every move. He nodded, looked up at the older man with apologetic eyes, hips still moving as he pleaded. "Please."
Derek nodded before hooking his arms under his armpits and hauling the younger man on top of him. If nothing else, Stiles had discovered a kink for being manhandled and hoped his next partner and his future mate was as strong as the werewolf he was straddling.
The thought that Derek soon wasn't gonna be his anymore made his heart clench in his tight, but the hurt was easily hidden by his overwhelming need to be filled.
"C'mon, li'l Omega," Derek urged, hands sliding up his thighs and cupping his ass. "Ride your Alpha."
The words brought a smile to the younger man's face, allowing him to shove aside any sadness about how their time was running out. Rising up to his knees, he held Derek's dick by the base, thumb rubbing the gland where his knot would form as he lined it up with his hole. The Alpha spread his cheeks and held them open as he slowly sank down, being filled by the other man's cock and making them both groan.
