Stiles chokes out a whimper at the soft lick of the man's hot tongue at the tip of his cock, making him shudder and moan. It was the hottest, sexiest thing he's ever seen outside of internet porn, the way Derek looks with his lips on his dick as he pulls his hand away from his cock, putting both on the wall to brace himself. Then he's feeling the wet, hot and engulfing heat of Derek's mouth around him.

"Oh god, oh fuck, Derek!" Stiles cries out, shuddering visibly as one hand drops to nest fingers into Derek's soft, dark hair, gripping lightly. "Oh my god, so good- you feel so good. S-Shit," he gasps out, knowing he won't last at all like this. His first blowjob. His first orgasm with someone else. With Derek.

Fuck.

"Derek, Derek, I can't- I'm-" He was so close already and when he feels Derek's throat around the head of his dick as he's taken all the way down he nearly comes right then and there. But he lasts at least a few pumps of his hips into Derek's mouth before he's crying out in pleasure.

His back arches, body bowing as his hips jerk when he comes, hot and thick down Derek's throat. He curls forward a little, gasping for breath and moaning Derek's name so loud he's sure it echoes in the otherwise empty room of the loft. He feels only slightly embarrassed for not lasting as long as he would have liked, but he's been keyed up since they got on the bed and Stiles blew him.
