He loses his house and through his cousin Ayami's help, he becomes the "acting caretaker" of the house. The main character Rikuto is a new resident of a share house.

What kind of life is in store for the timid man? It was the beginning of a new life in the midst of expectation and anxiety.

However, the people who live with him are sex-loving bitches! Rikuto, who has no immunity to the opposite sex, is being pestered by a bitchy gal, Airisa, his junior. With her excellent carnal technique, she makes you ejaculate in no time.

The pity that comes up to the ejaculation which is faster than I thought. This is no way to approach the rugged masculine figure I aspire to be!

More than that, this kind of premature ejaculation will disillusion you when you have sex with someone you love! She was so shocked to see him say such a thing. Airisa suggested that she could help him with his premature ejaculation.
