My selfish sister-in-law who ran away from home and tumbled into me, and as a newlywed, I was forced to abstain from celibacy for a month.

Unable to bear the brother-in-law's play with women, my wife's sister, Riho, tumbled into our house. My brother-in-law says he will pay for living expenses, but when Riho is around, his wife becomes embarrassed and even ends up being banned from sex. As a newlywed, I have to endure the life of being forced to be patient... Without realizing my worries, Riho is walking around our house today in defenseless clothing. It's about time for this abstinence life, and it seems like my sister-in-law will reach her limits in her revealing outfit...
