King Calvin, a powerhouse of a man, puts King Mark through his paces in this intense CBT session. Calvin's massive hands grip Mark's balls, massaging and squeezing with just the right amount of pressure. Mark winces, but Calvin's stern gaze keeps him in check. Calvin then grabs a pair of clamps, attaching them to Mark's sensitive nuts, making him gasp. The workout concludes with Calvin's signature ballbusting, where he knees Mark's nuts, reducing him to a whimpering mess.
