Aching with desire, the bound boy clenches his fists, pulling at his restraints. His eyes locked on his throbbing erection, he works it furiously, the sound of his slick flesh slapping echoing in the room. His tied balls swing heavily, the pressure intense, driving him closer to the edge. With a cry, he erupts, his cock pulsing as it coats him in rope after rope of hot, sticky cum.
