In this intense gay BDSM session, Kings Calvin and Mark delve into the dark world of CBT and ballbusting. Calvin, the dominant femdom, commands Mark to kneel, his chastity device glinting in the dim light. Calvin, taking a cue from the female doms they admire, uses her strong hands to deliver precise, powerful blows to Mark's bulge. Mark's cries of pain fill the room, but Calvin, ever the sadistic taskmaster, demands more. Mark, a seasoned sub, takes it all, his body quivering with endorphins, his mind lost in the sweet, agonizing embrace of complete submission.
