Arisa lives with her husband and father-in-law. While she had no complaints about their life together... one day, her husband confided in her, "The doctor told me I'm infertile." The wife who wanted children couldn't hide her shock. After discussing it between the two of them, they reached a conclusion that defies common sense. It was for the father-in-law and his daughter-in-law to have sex and make a child. Confused, the father-in-law began to see his cute and perfectly figured daughter-in-law as a woman, peeping on her in the bath and getting excited as he embraced her. However, two friends of the father-in-law who had witnessed this act proposed, "Let us help with making the baby too."
