JUQ-323 Son's ambition to fuck his stepmother

When I became president of the university, I was surprised by the lack of ambition of my son, Gaku. Thinking that she would change if she got married, she forced the professor, Oshima's niece, Sora, to set her up, but... In reality, the person who was targeting her was none other than Toru. He pretended to be a strict father and forbade them to have premarital sex until marriage. One year later, Toru sent Manabu on a five-day business trip and implemented a plan to train Sora.
