In the privacy of his cell, a prisoner indulges in a steamy solo session. His thick cock stands at attention, begging for his touch. He obliges, wrapping his calloused hand around his shaft, pumping steadily. His grip tightens, the friction sending jolts of pleasure through him. His body tenses, and with a final, powerful stroke, he comes undone, his cock pulsing as it coats his stomach and the floor with his hot, sticky release.
