He jerks his hand fast and a little rough, cheeks hollowing as he sucks harder, wanting to feel Derek coming down his throat. And he's rewarded for it, the first hot spurt startling but he eagerly sucks it all down, swallowing the thick, messy come as it shoots into his mouth. He's watching Derek the whole time, watching how he arches and shakes for him.

Stiles pulls off with a gasp and a filthy wet pop, panting softly as he does exactly as he'd said before and licks Derek's cock clean. God, hearing Derek say his name like that had to have been the hottest thing he's ever heard.

Moving up to straddle the man's thighs, Stiles shoves his boxers down and keeps himself levered up with one hand on Derek's chest while his other grabs his aching, neglected cock and starts fisting it quickly. "Ngh, Derek.." Little whimpers and soft needy sounds escaped him as he gets himself off.
