my mother was peeked at, and her family was away from home.

A sloppy event that happened in my home after all the family went out. One day, when he returned home to pick up something he had forgotten, he saw his mother roaring while looking at her hidden erotic book. "...it's not like she was so erotic!" After that, the son often stole his mother's appearance. At last, I was tempted by other people who visited my house such as a courier delivery worker and an electric shop for air conditioning repairs, and came across the moment when I ran into an affair.
