Widow Rena Sakuragi raped by her husband's stepchild

I didn't think she was my mother from the beginning...I couldn't believe it. I peeked at Kotomi's draft and got horny. She took a peek at Kotomi's changing books, and she indulged in masturbation. She was shocked to hear the sounds of Kotomi and her father having sex. ...Yes, my first love was my girlfriend's stepmother, Kotomi. ``What are you going to do when your father dies!'' That day, just after her father's funeral, I attempted to rape Kotomi and ran out of her house.
