After losing his job, Natsumi's brother-in-law Makoto moves into the Matsuoka home and immediately disgusts her. He leaves rooms in chaos, drinks, smokes, and acts violently, so she asks her husband to throw him out. Days later, while her husband is away, she catches Makoto stealing the couple's living money and tells him to leave. Enraged, he pins her down, and despite her revulsion, his filthy cock drives her into orgasm after orgasm.
