Due to his daughter's infidelity, the stepson is suffering. After hearing this fact, Rui (Ayagawa Rui) apologized, thinking it was her fault for raising him poorly, and then pulled down his pants on the spot. If he has pent-up desires because of her daughter, she will take care of it herself. That would be her atonement as a mother. With that in mind, Rui performed oral service. However, this act was so lewd that it aroused forbidden desires within the stepson.
