Natsuki, a married woman who married a man with a child and became a mother at a young age. I lived without any inconvenience and was happily embraced by my husband almost every day. However, when my husband went on a business trip and felt a little lonely and masturbated, his son's friend who came to play saw him. From that point on, my daily life has disappeared. My son's friends make me a sexual outlet and gradually lose my reason. A married woman who is tossed by young men and swings between pleasure and guilt!
