Jo, a young, smooth twink, finds himself alone in the bathroom, his cock already hard and throbbing. He climbs into the bathtub, the cool water sending shivers down his spine. His hand wraps around his thick, veiny cock, stroking it slowly at first, then faster, his moans filling the room. He lets out a low grunt as he reaches down to cup his balls, his other hand slapping against his wet skin, the sound echoing in the small room.
