JUQ-323 During the five days my husband was away, I was ordered to abstain until our first night together. Instead, I was completely trained body and mind by my lecherous stepfather──. An unwanted political marriage, his target was me… Sora Amakawa.

When I became the president of the university, I was amazed at the lack of ambition of my son, Gaku. Thinking that things might change if he gets married, he forcibly makes the professor Oshima's niece Sora a matchmaking partner, but... In fact, it was none other than Toru who was aiming for her. He pretended to be a strict father and forbade them from having premarital sex until marriage. A year later, Toru sends Manabu on a five-day business trip, and he puts into practice his plan to train Sora.
