Standing tall against the green wall, slim naked guy grips his thick cock firmly and strokes with steady rhythm from root to swollen head. Fingers slide up and down the veined shaft, pubes dark and bushy around the base, as his lean torso flexes slightly with each pull. He angles his hips forward, hand twisting at the tip while precum glistens in the light, building speed across frames. Body tenses harder, strokes quicken relentlessly until the cock throbs visibly in his tightening grasp.
