Mao, a stunning masochistic slave, obeys her master by visiting his room completely naked beneath a single coat. Though deeply embarrassed, she is intensely aroused. She gives him a blowjob outside the front door before they have sex. Treated like a dog, she is pushed deeper into submission with dildo deep-throat and masturbation, then bound with her hands behind her back and made to squirt with toys before serving her master with her tongue and pussy.
