Hikari lived apart from her husband. The days of no sex continued. One day, I witnessed my daughter having sex with her boyfriend, and something shook my mind. My daughter was away from home, and she met her boyfriend who came to pick up something she had forgotten. She was always worried about her mother. She couldn't stand it. Her teenage sexual desire exploded and she revealed her big breasts and attractive body. Not completely without ink. She thought so too, but she... she felt ashamed, so ink betrayed her daughter and committed adultery.
