Sena Amakawa from Musashi Kosugi is 30 years old. Seina has only been married for two years, but she gave birth to a boy half a year ago, and as a mother, she works hard every day to raise her child. Such a happy Amakawa family, but in reality it is a sexless state that has not had sex even once since becoming pregnant. It seems that Mr. Seina tried to approach him several times, but he seems to have fallen into extreme frustration, coupled with the increase in libido after giving birth because his husband does not seem to be interested. When he was worried about what to do, he told his best friend who could only consult about the existence of a mature woman AV and decided to appear.
