Hinano, who ran away from home, turns out to be a masochistic girl who can't concentrate on studying because she's always masturbating! "I'm a bad girl. Please punish me," she begs on her knees, and her uncle unleashes a spanking on her! Bound with cotton rope behind her back, she trembles with pleasure and becomes drenched in her own juices. She shows up at the front door at night wearing only a coat and no underwear, and declares, "I've come to be punished again," in heat! With a collar and leash, she's ****** onto all fours and subjected to nipple clips and a vibrator, making her make ecstatic faces repeatedly! At the end of a complete training session that satisfies her abnormal masochistic desires to the extreme, her body and soul descend into that of a bitch!
