The trembling slave is introduced to the cruel world of CBT by his dominant Mistress. She commands him to strip, then makes him sit on a hard, cold chair, his bare balls exposed and vulnerable. Mistress begins her 'lesson,' applying increasing pressure with her sharp heels, from gentle taps to intense, ball-crushing stomps. The slave's cries of pain only fuel her sadistic pleasure, as she continues to push his limits, testing just how much pain his 'pathetic little balls' can take.
