The younger brother made a very wrong decision to live with his unmarried brother with his beautiful young wife Anzai, so it was like offering himself to someone else's mouth. Indeed, the brother has been alone for a long time, so it is natural that he has a desire for sex, but the factor that caused his craving was his brother's wife. She is really a lewd woman, who has not won her brother enough now to solicit her brother's love. But she is also very wise when she constantly does sexy and erotic acts, typically deliberately wearing pants with holes in the intimate area on the day of yoga practice with her brother there so that he can make him can't stand it anymore and have to push her out of sex. After that time, they had feelings for each other, a very shady but also very deep feeling, so much so that when the wife was Bj for her husband, the brother also secretly stole from behind her.
