Anonymous hands, veined and strong, expertly work a stiff shaft in the dim light of an unseen room. A lone man, hidden from view, grips his throbbing cock with urgency, the sound of flesh slapping flesh echoing softly. His rhythm is steady, practiced, as he strokes his length, pre-cum lubricating his tight grip. The camera lingers on his hands, calloused and rough, a stark contrast to the smooth, pink flesh he pleasures.
