The Endless Torment Treadmill

In complete sensory deprivation, straitjacket and locked in high heels, suspended above the ground, Mistress Sidonias slave is ready for some unusual training. She enjoys yanking him by the cock and balls, slapping them with her crop until he gets hard, oblivious to what is going to be happening. Mistress brings out the treadmill and positions it under the suspended slave to create a unique punishemt and training regime.
