Incest [silent] Incest There's a dad next to me...

Satomi, a young and beautiful wife, remarried and lived happily with her husband and stepchild Akio, but recently she has been acting strangely wrong. Suddenly he was standing behind Satomi and trying to hug her... Even if she consulted her husband, Satomi couldn't take it, so she decided to think that it was just her imagination... Just as soon as Akio comes across her masturbating in her Satomi's underwear, she is attacked.
