Minami Nakajima is a 40-year-old homemaker in her eighth year of marriage. Her approachable warmth and maternal charm captivate the staff from the moment she arrives on her bicycle. Shyly, she confesses that she has not had a cock inside her for five years. She copes with the sexless marriage through daily masturbation and explicit posts on a secret social-media account, gradually discovering the thrill of exposing her body to countless strangers. Wanting to reveal even more of herself and feel her deepest pussy pounded to the limit, she finally reaches the end of her patience and comes to the studio for her porn debut.
