"Dominating Supe Balls" sees King Calvin and King Mark, two muscular, kinky gay men, indulge in a ballbusting, chastity-ridden BDSM session. Calvin, the femdom, teases Mark with his bulging bulge, taunting him with the pain he's about to inflict. Mark, in a state of heightened anticipation, is made to worship Calvin's crotch, his own balls aching in their cage. Calvin then subjects him to a intense, prolonged CBT session, using his strong hands and a custom-made ball crusher, pushing Mark to his masochistic limits. The scene culminates in a humiliating, yet satisfying orgasm for Mark, controlled entirely by Calvin.
