Derek stills and groans softly when Stiles touches him, then begins moving his hip against Stiles' hand. A part of him was yelling at him to stop and pull back before he hurt Stiles, but another part was telling him how much more relaxed Stiles would be if he could come, how much better he would sleep if Derek just saw things through. He shifted, trying to make his position easier on Stiles.

He raises his eyes to meet Stiles, licking his lips before speaking. "Anything you want," he promises, finding it hard to breathe. He just wants more but knows that this time, he has to settle for this, just for now. His thumb circles the tip of Stiles' cock before gripping him and stroking, imagining they're both naked, not mostly clothed. "I want to taste every inch of you, lick a path from your cock to your mouth. I want to taste myself on your tongue, fuck, Stiles," he moans, thrusting against his hand. "I want to know what it feels like to have you fuck me."
