Calvin, the eager sub, awaits his dom, King Mark, in a state of heightened anticipation. His chastity device has been on for days, and his balls ache with the need for release. Mark arrives, his feet bare and commanding. He orders Calvin to service him, and Calvin eagerly sucks Mark's cock, feeling it grow hard in his mouth. But Mark has other plans. He brings out a variety of CBT toys, from clover clamps to a ball stretcher. Calvin's screams fill the dungeon, but Mark remains firm, pushing Calvin's boundaries. Finally, Mark allows Calvin to cum, but only after he's licked Mark's feet clean of Calvin's own spilled cum.
