When Shinji reunites with his college friend Takeshi, Takeshi boasts that his beautiful wife Yuki still eagerly has sex with him three times a week. Single and extraordinarily virile, Shinji is consumed by jealousy. He visits Yuki and forcibly pins her down. She resists, yet his relentless stamina drives her to orgasm again and again. After five days of being fucked and creampied four times each day—a total of 20 loads—Yuki can no longer feel satisfied by her husband.
