that day when my father was away from home on a business trip... For the first time, I felt greedy for my mother. He was asked to bring soap by his mother Tomomi while taking a bath. I took the soap as I was told and opened the bathroom door. When I was a child, my mother's nakedness made me feel so nervous that I hardened the crotch. "Well, what are you thinking?" At that time, Tomomi had never dreamed of her mother being conscious of her son as an opposite sex, but the relationship between the two began to be exciting on this day.
