A curious twink, confined in chastity, can't resist the temptation of a massive cock. He teases and rides it, feeling it throb against his tight hole. His solo session escalates as he releases his chastity device, fingering his prostate and moaning loudly. The big cock's thick veins push against his walls, sending shivers down his spine. He cums hard, coating his abdomen with his load, proving his chastity limit.
