In the dimly lit dungeon, kings of gay BDSM, Calvin and Mark, reign supreme. Calvin, the dominant dom, commands Mark, his submissive counterpart, to worship his feet. Mark obeys, kissing and licking Calvin's soles, sending shivers of pleasure up his dom's spine. But worship isn't the only thing on the menu. Calvin's ball-busting streak takes over as he orders Mark to crush his balls, causing him to grimace in pain and pleasure. The dungeon echoes with their moans and the clink of Mark's chastity device.
