Billy, a straight-laced twink, finds himself alone and horny. He can't help but let his curiosity get the better of him as he wraps his hand around his massive, throbbing cock. Slowly, he pumps his fist, feeling every vein and ridge, his breath quickening. He imagines a forbidden encounter, his body tensing with the thought. He picks up speed, his balls tightening, and with a final, desperate stroke, Billy's cock pulses, sending a stream of hot cum onto his stomach.
