In order to support my pregnant wife, my mother-in-law, Sayuri, came to Tokyo from my wife's parents' home. I was in a cold war with my girlfriend's wife, and I was prohibited from drinking alcohol or masturbating, so I remained sane even though I was confused by Sayuri's seductiveness. Then, one night, when I confessed my troubles in my work and personal life to Sayuri-san, she gently stroked my head and spoiled me. It doesn't stop there, he also suffers because of his girlfriend's daughter.
