Ball Kicking / Ball Busting / Testicle Kicking is a form of CBT in which a male Submissive desires to be kicked in the testicles, or a Mistress desires to kick a male slave in the testicles. For male Submissives, perhaps the sexiest and most humiliating type of CBT is genitals flattened under high heeled shoes and then under Mistress perfectly shaped feet and toes.
