The submissive's chastity device is unlocked, but not for the relief he craves. His mistress demands a humiliating handjob, pushing his boundaries. She dominates him, making him worship her body, his own needs ignored. His cock aches, leaking pre-cum, as he struggles to maintain control. Finally, she relents, ordering him to cum, but not before making him beg, his humiliation complete as he spills his load onto the floor, gasping for breath.
