Your dad is marrying a lady with a checkered past. She wants to have a heart to heart with you as she will soon be your stepmom. She tells you that things are going to change and she's sure one of the reasons your dad is marrying her is to help you out. You are a Virgin and she's a former whore. She wants to break you in gently though,so she starts by showing off her body and letting you really take it in. This is a change you could get used to.
