Three men, captivated by the beauty of their Mistress, vowed to dedicate their entire lives to her. They abandoned their families and possessions, choosing to live as slaves in the Mistress's mansion, serving her through constant cunnilingus and household chores. Each man wears a chastity device at all times, with strict control over ejaculation. Masturbation is forbidden without the Mistress's permission. Since she has a strong libido, she demands oral service constantly, and any mistakes or laziness result in further delays of their precious release. Desperate for permission to cum, the men perform cunnilingus fervently every day, keeping the Mistress's pussy perpetually wet with saliva, never allowing it to dry throughout the day. Under these harsh conditions, the men passionately strive to fulfill every desire of their Mistress.
