A captive woman is bound and relentlessly trained to have her nipples developed into a depraved masochistic state! With pen torture, suction, brushes, clothespins, and more, she is subjected to intense and heavy nipple torment, moaning obscenely with pleasure! Female detectives, exorcists, schoolgirls, and female tutors have their sensitive nipples erect and exposed, reaching nipple orgasms with faces of ecstasy! The painful yet pleasurable sensation of pinched nipples melts her body and mind. Women fallen into nipple slavery serve with drool and vaginal fluids, crying in joy!
