In the throes of intense gay BDSM, King Calvin and King Mark explore the exquisite pain of CBT. Calvin, the dominant one, restrains Mark in intricate bondage, his balls vulnerable and aching. Mark, the sub, moans as Calvin's skilled hands manipulate his sensitive orbs. The game escalates, with Calvin employing clamps, slaps, and even a ball stretcher. Mark's humiliation and pleasure intertwine as he endures the intense sensations, his cock rock-hard despite the agony.
