Ballbusting is a type of BDSM porn that centers around the intense pleasure and pain experienced by the submissive partner when their genital area is kicked, stomped, or otherwise pounded. It often involves the use of various implements such as paddles, whips, canes, and other similar tools. Ballbusting can be an incredibly satisfying experience for both partners involved and is often used as a form of kinky power play between Dominant and submissive partners.
