In a secluded gym, Vanessa90 oversees a chastity slave's grueling exercise routine. The slave, locked in a tight device, struggles through sets of bench press, pull-ups, and planks, his body trembling with exertion and denial. His boyfriend, the master of this cruel game, watches with sadistic pleasure, daring the slave to push harder, to fight his body's urges. The air is thick with the slave's sweat and the scent of his leaking pre-cum, a constant reminder of his frustrated arousal. The session ends with the slave, panting and desperate, pleading for release, only to be denied by his merciless boyfriend.
