Yuta reunites with his college friend Takeshi, who boasts that his beautiful, sex-loving wife Kana still fucks him three times a week. Single, frustrated, and insatiable, Yuta secretly visits Kana and forces her down. She resists but still climaxes under his uncontrollable stamina. He then returns five days a week, creampieing her four times per visit for a total of twenty loads, until Kana finds her husband can no longer satisfy her and gives herself over to Yuta.
