incest, i'm going to go out to my mother on the 50th street.

One day, Isoji's mother witnesses her son's self-consolation and notices that her crotch is hot and wet. She is a 50-street mother who can not suppress the intense desire for sexuality hidden in a fully ripe and gorgeous body, and continues to comfort herself. When his son, too, feels abnormal excitement and ripeness in the naked body of his mother who lays down with his breath, he speaks of Oma-ko, a sensitive thin eyebrow of Isoji's mother, drowning violently and ascending to heaven many times. The mother and son, who knew of the forbidden apology, were infuriated over and over again by jealousy.
