one night and two days after being pulled out by my wife's sister who suddenly came to push, shirosaki yuko.

Atsushi enjoys her life by herself while she is single because the wife who has been pregnant and does not want to give birth is going home. Without contacting him, his wife's older sister Ayako came and said "I came to see the situation because I thought that I was in trouble by myself," so she ignored Atsushi and decided to stay forcibly. Then at night, when Atsushi is in the bath, she flushes her back, and the lion appeared in the bathroom was naked.
