Stiles groans at the touch, those warm hands on his shoulders, strong fingers that could rend a person heavy on his skin. He trails his lips along Derek's stomach, kissing his way down as his fingers tease along the hem of his briefs. Even with just a human nose he can smell Derek's arousal, his heavy musky scent that makes the teen's mouth water. The man's cock is straining under the cotton material and panting breathlessly Stiles lowers his head and presses his mouth along the thick line of Derek's cock.

He mouths at the bulge, wetting the material as he laves his tongue along it, feeling it twitch beneath his lips. His hands bypass tugging the briefs down to instead smooth along the man's muscled thighs, moaning softly along his dick. Despite his display, Stiles hasn't actually done this before, though he's watched numerous porn videos where guys blew each other.

Dragging his hands back up to Derek's hips, he does the same with his tongue along the man's dick, teasing the head through the material with the tip of his tongue before finally, finally tugging the briefs down and letting the man's erection spring free.
