A son who hates his father's remarriage partner, Yuuki. He hits Yuuki with anger that he can't forget his real mother, and points out every little mistake. However, Yuuki begins to feel pleasure from the punishment and bullying that should be painful. One day, I found out that my son saw the stains on my panties that had been wetted by bullying. The son curses Yuuki as ``a lewd woman without a sense of chastity'' and thrusts a vibrator into her to make her walk like a dog.
