King Calvin, the dominant gay coach, punishes his loser sub, Mark, in an intense BDSM session. Mark, bound and helpless, endures Calvin's brutal CBT, his balls turning red and tender under Calvin's skilled domination. Calvin's strong, dominant presence fills the room as he commands Mark to suck his cock, making the sub gag and choke. Mark's eyes water, but he eagerly takes every inch, desperate to please his master. Calvin, satisfied with Mark's performance, rewards him with a taste of his own cum before locking him back into chastity, leaving Mark craving more.
