I was born into my son's slave by raising my mother.

His son is disliked by his father's new wife, Yuki. He places his unforgettable frustration on Yuuki, and points out every small mistake. However, Yuuki begins to feel pleasure from the pain of being torture and bullying, which should be painful. One day, when my son saw the stains from his panties that he had been experiencing and felt by his son. The son begins sexually raising Yuuki, insulting him as a "slutty woman with no sense of chastity," and thrusts in a vibrator and makes him walk like a dog.
