妻子去旅行，让她的继父照顾她的继女，但他把她放在了继母的位置上

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.
