Toru reunites with his college friend Takeshi, who boasts that his beautiful, sex-loving wife Haruka still fucks him three times a week. Jealous and extremely virile, Toru secretly visits Haruka and forces her down. Though she resists, his relentless stamina drives her to climax. Soon he is creampieing her three or four times a session, five days a week—18 loads in all—until Takeshi can no longer satisfy her.
