Mayu, a wife who secretly buys luxury watches and bags without telling her husband or father-in-law. She is pressed to pay off the debt and borrows money from her uncle using her ripe body as collateral. She also turns to loan sharks and is unable to pay it off, so she becomes his sex slave on the condition that her father-in-law takes over the debt. Her delicate body is penetrated by a thick cock and reaches a convulsive climax. She is violently violated by the loan shark and trained to be a sex toy, and then her uncle joins in, raping her holes with two cocks and turning her face into a milky white mess.
