Takeshi Karaki stands up to fulfill the wishes of the client who wants to have sexual intercourse with a close relative ... Voyeur the whole incest plan! A request from a son who grew up listening to the complexion of his parents who have a bad relationship with his wife and later learned of his mother's affair and resented him. A fake massage shop where a mother who knows nothing was brought to her son. A mother who reacts sensitively to treatments in fragile areas. A mother who tells a lie without skinship for many years is groped by her genitals and feels warped and cums. Ascended immediately when stabbed by a penis, screamed when struck from behind with an eye mask and ascended again. The mother, who does not know her true identity even after being replaced by her son, who called her assistant, faints in agony and raises a loud voice. Even after spoilers, she lends her body to her son and bathes in a large amount of sperm.
