King Mark, the dominant force he is, takes Calvin through a whirlwind of sensations in this intense CBT session. From the moment Calvin's chastity device is removed, his aching cock and balls are subjected to Mark's every whim. From gentle caresses with a riding crop to harsh clamps and intense electric shocks, Calvin's endurance is pushed to the limit. Mark's foot, clad in a shiny, red boot, presses down on Calvin's balls, the heel grinding into his sensitive flesh as he struggles to maintain his composure. The dungeon resounds with his cries of pleasure and pain, a symphony of submission to his master's will.
