``Miyu Shitara'' is a 32-year-old single mother raising a newborn son. Her husband, who used to work at the same convenience store, evaporated two years ago, and she now spends irregular and busy days as her store manager instead of her husband. The reason she applied to be an ``extra'' in AV was money and her interest in AV. The director tells her that she wants to get used to being on set, and when she sees the actor's dick right in front of her, she can't resist and takes it in her mouth. Later on, she decided that her pent-up sexual desire would make it unnecessary for her to be just an extra, so her director wanted to shoot her in the lead role. She had no sex and her body, which had been untouched for five years, was played with and her shaved pussy was filled with her love juices.
