I live with my father and am a bullied kid. One day, a woman named Ryoka comes to our house claiming to be my new mother. She is beautiful and has an amazing figure, so I was happy at first, but then I found out she was after our money and got angry, handing her over to the delinquents. Reluctantly, Ryoka becomes a sex toy for the delinquents, but gradually gets addicted to the pleasure of young penises, ultimately even becoming addicted to my stepbrother's penis, transforming into a lewd stepmother.
