It's almost too much for him to take, Derek's hands on him, working him over and making him pant and moan. Each slide of Derek's hand on his dick from base to tip has him shaking. He shifts his hand to dip into Derek's boxers, wrapping those long fingers around the werewolf's hard cock, jacking him at a quickened pace.

His hand jerks a little when he hears that Derek wants Stiles inside him, and the teen almost comes right then and there, moaning loudly as his hips jerk hard upward into his hand. "Oh, fuck, Derek!" Stiles gasps out, fingers squeezing momentarily before continuing their fast pace.
