ADN-556 I had sexual relations with my stepson. (Natsume Nishiharu - Natsume Ayaka)

My husband has a stepson named Yuta. He was initially a well-behaved boy. However, after we started living together, he began skipping school frequently, hanging out with girls, and his behavior gradually deteriorated… One day, Yuta saw a photo of me masturbating. Maybe it was my fault that Yuta changed…? Just as I was thinking this, Yuta pushed me down while my husband was asleep… and that's when we started having a physical relationship.
