After being fired from his company and losing his home, Yuuta was allowed to stay at his brother-in-law's house until he found a new job. However, he had no place in his brother-in-law's house and was constantly ridiculed by his brother-in-law for being a pathetic man who was still a virgin at 30 years old. Wanting to gain confidence, Yuuta asked his brother-in-law's wife, Kanna, to take away his virginity. Sympathizing with Yuuta, Kanna agreed to let him have sex with her, but as soon as she was inserted, she was overcome with a numbing sensation and pleasure. She then demanded multiple times to have creampie sex again.
