Tit-slapping is a sadistic fetish of slapping a woman's breasts for sexual arousal. It is one of the Japanese fetishes imported into American mainstream fetish porn. One western form features woman on woman tit slapping in a cat-fight scenario. A more sadistic form features a bound woman with
large breasts being subjected to violent breast slapping, twisting, pulling and pinching, resulting in tears, obvious pain,
discoloration and bruising to the breast. It is a form of sadistic
humiliation.
