Mao and Kenji had been best friends for years, but there was always a gulf between them. Mao was born into a wealthy family, blessed with good luck, and seemed to have everything, leaving Kenji with a constant inferiority complex. When Kenji is invited to Mao's home as usual, he meets Mao's girlfriend Eimi. Cute, kind, and utterly devoted to Mao, she pushes Kenji's jealousy past its breaking point, and he decides to steal everything his friend has. Using hypnosis, he turns Eimi into his affectionate live-in girlfriend and repeatedly creampies her until she becomes pregnant with his child.
