Unable to pay the rent on her apartment, Rin Sasahara is forced to let her brother-in-law, Ryuichi, move in. He drinks, smokes, and behaves rudely and aggressively—the absolute worst kind of man imaginable. Rin despises him intensely, and when she catches him stealing 10,000 yen from her wallet while her husband is away, she finally snaps, blurting out, "Just leave already!" Enraged, Ryuichi pins her down. Powerless to resist, Rin is repeatedly forced to orgasm by the filthy man's body, despite her utter revulsion.
