In a private, dimly lit room, a young man stands alone, his cock throbbing with anticipation. He's here for one purpose: to paint the walls with his seed. His hand, slick with pre-cum, strokes his dick with urgency. He's close, so close. His breath hitches, body tenses, and with a guttural groan, he unleashes, his dick pulsing as it sprays ropes of hot, white cum onto the waiting surface.
