The wife went on a trip and asked her stepfather to take care of her stepdaughter, but he put her in her stepmother's place.

The husband came home and saw that his wife was not there. After talking to her on the phone, she asked him to take care of her stepdaughter and that she would be away for 3 days. He called his stepdaughter and told him that she should replace her stepmother, so he seduced her and had sex with her.
