In a private dungeon, a solitary masochist indulges in intense CBT play. He suspends himself, vulnerable and exposed, then attaches heavy clamps to his sensitive testicles. The clamps bite down, sending jolts of pain that morph into a strange, exhilarating pleasure. He writhes, his body dripping with sweat, as he pushes his limits, seeking the sweet release that only this cruel, solitary game can provide.
