In the throes of self-pleasure, an uncut, black cock pulses, its owner's eyes locked on the rope cinched tight around his large, low-hanging balls. He tugs at the rope, stretching his scrotum, sensation coursing through him. His cockhead glistens with pre-cum, his strokes becoming more urgent. His body tenses, and with a final, deep groan, he erupts, his cum spewing forth in thick ropes, painting his abdomen and chest with his sticky, white seed.
