In a dimly lit dungeon, King Mark tests his new sub's limits. Wearing nothing but a chastity device and a collar, the sub kneels before Mark, awaiting his commands. Mark, a dominant force, commands the sub to rim and worship his boots, each lick echoing with reverence. As the sub's enthusiasm grows, so does Mark's desire to inflict pain. He orders the sub to lie back, revealing his caged cock, throbbing with need. Mark, with a sadistic grin, slowly applies pressure to the sub's balls with his dominant foot, drawing out cries of pleasure and pain, a symphony of Mark's power and the sub's devotion.
