In the world of gay BDSM, King Calvin and King Mark push boundaries with a CBT chastity challenge. Calvin, the dominant femme, teases Mark, his locked-up sub, with painful touches and humiliating commands. Mark's bulge struggles against the confines of his chastity device, while Calvin's own, massive cock strains against his jockstrap. The power dynamic shifts as Calvin forces Mark to worship his feet, lick his boots, and endure a merciless, full-body assault. Mark's whimpers and Calvin's growls fill the room, creating a symphony of kinky, male domination.
