This is a record of the taboo incest between a mother with large breasts and a long tongue, who, despite knowing it's wrong, has normalized performing sexual acts on her hikkikomori son, and her son. The hikikomori son can't seem to wean himself off his mother's breasts. As his desires escalate due to his mother's daily oral sex, he begins to demand vaginal sex. The mother accepts her son's penis and semen with maternal love and her vagina.
