I tried for a month to try to get pregnant with my wife and I saved up... My wife's sister is taking out my sperm with her huge nipples without a bra, as she's not good enough for her husband, who is dying for her.

Junichi, who has been married for three years, and his wife Miki, are actively trying to find a fertility, and their husbands are living abstinence for a month, just before the wife's day of ovulation, when they are likely to get pregnant. Meanwhile, Miki's older sister Maria, who lives in the same apartment building, also had her husband who had been experiencing an end-of-life, but she wanted a child before her younger sister, so as her sister and her husband were due for have a baby, she came in to seduce him in revealing clothes and robbed Junichi's sperm.
