Stiles is on his laptop when the pain hits so hard that he's doubled over clutching his head with one hand and his stomach with the other. He doesn't know when the pain stops, only that there's a hand on his shoulder and a voice calling his name. A voice that sounds like his dad.

"Stiles!" His dad calls again and Stiles groans sitting up slowly. "Kiddo, what the hell just happened? I heard you screaming from downstairs." Stiles could hear the worry in the Sheriffs voice.

"I...I don't know, dad. Sorry for scaring you." Stiles says slowly. He feels like if he were to get up, he'd end up puking out his guts and whatever else was in his body. When he was sure he could move again without puking, Stiles walked over to his bed and collapsed on the mattress face down. He heard his dad mutter something before the door closed behind him. Just when he was on the brink of sleep, his phone buzzed a few times. Frowning at the sender, Stiles opened up the text message.

Dereks on da way 2 u

Stiles groaned lazily typing out Use ENGLISH man! Why's he coming here?

The reply was faster than Scott's usual reply rate; smethng hppnd chcking on u

"Oh my god." Stiles groaned again covering his face with his hands. His window slid open slowly before Derek silently crept into the room. "What happened that has you personally checking in on me? Not that you don't do it on a normal basis cause you do. Okay, I feel you giving me that STILES, SHUT UP look, so I'm just gonna be over here…" Stiles trailed off with a squeak (a manly one at that) when Derek sat down next to him on the bed. Derek was the one to break the silence that had fallen over them.

"Everyone else was at Scott's house. I'm only checking on you. How's your head?" Stiles gaped at him for a moment before rubbing a hand over his short hair roughly.

"My head is perfectly fine. Thank you very much for asking, but why are you asking?" Stiles flailed slightly when Derek's hot hand pressed against the back of his neck. The man in question only grunted squeezing briefly.

"I heard you screaming… from Scott's. That's why I'm asking. Now, tell the truth because I know you were lying." There was a touch of concern in the Alpha's voice that had Stiles smashing his pillow into his face.

"Dad said he heard me from downstairs. I bet the neighbors are wondering what's up with the Sheriffs kid this time." Stiles' voice came out muffled due to the fluffiness of his pillow. Derek frowned pulling the pillow from the teens grip. Stiles blinked up at the face that was suddenly hovering over him. "What?"

"How long has this been happening?" The older man asked quietly. Stiles' eyes widened at the look in the Alphas eyes. "Stiles."

"Oh, um, it only happened today. While I was doing homework, but I kept getting twinges of pain during school..." Stiles muttered turning his head to get away from those piercing hazel eyes. Derek nodded moving back slightly, not that it helped much since he was still in Stiles' personal space. He did that thing where his eyebrows sort of frowned and his nose scrunched up as if he'd smelt something horrible and with his super senses that would be completely possible. "Ugh, stop making that face." When Derek cocked an eyebrow, Stiles flushed. And when Derek buried his nose in the side of his neck and inhaled his scent, Stiles will deny the sound that came out of his mouth if he's ever questioned.

"You still smell of pain." Derek murmured lips brushing against Stiles' skin with every word. Stiles flailed his arms uselessly before letting them drop onto his bed, but Stiles' body had other thoughts as one arm rested across Derek's lower back and the other tangled into his hair. The older man let out a puff of breath that sounded like a chuckle and then he nipped the pulse point under his mouth rough enough to bruise. "I'm sorry. The pain you felt was because of me." Stiles gasped arching his back slightly when a hand trailed down his side, slipped into the space created and pressed lightly into the dip above his ass.

"W-what do you mean?"Stiles paused at the breathy way the words came out, biting down on his lower lip hard enough to draw blood in order to stifle the moan that wanted to come out when Derek rolled his hips slightly against Stiles'.

"That was me accepting the wolfs mate. My mate." Derek replied trailing his tongue up the tendon in the boy's neck. He stopped when he reached his jaw, nipping it lightly before moving until there was only a centimeter of space left between their mouths.

"If you have a mate, then why are you doing this?" Stiles' brain was starting to function again, but barely as Derek rolled his hips once more. Derek smirked letting his tongue dart out to capture a droplet of blood.

"My mate is a spastic teenager who doesn't know how to shut up even when he's being seduced. Does that sound like anyone you know?" Derek didn't even wait for an answer as he let his head drop that last centimeter, claiming the boy's lips in a hungry, but sort of gentle kiss. When they parted, Stiles squeaked out an answer.

"Me?" Derek nodded swooping in for another kiss. And this time, Stiles participated right away.
