In the dimly lit room, a lone figure, Sperma, finds solace in his own company. His hand, slick with anticipation, wraps around his throbbing cock. He strokes, his breath hitching as he teases himself to the brink. The room fills with his wet, slapping sounds, a symphony of his desire. His body tenses, and with a final, shuddering thrust, his hot seed erupts, coating his fist and dripping onto the floor.
