Mazohrs, the Japanese BDSM star, is bound and helpless, his cock standing at attention. The domme, a cruel mistress, takes his throbbing erection in her gloved hand, slowly stroking it to maintain its rock-hard state. She then proceeds to crush his glans with various implements, from her high-heeled boots to a heavy stone. Mazohrs' cries of pain fill the room, his cock leaking pre-cum as it's subjected to the most intense CBT. The domme, savoring his suffering, ensures his penis remains erect and abused until he's finally granted release.
