Reluctant step-Mom: Keeping it in the Family

Your younger cousin and aunt recently moved in with you and your step-mom, and seeing as she doesn't know anybody in your town yet, you take your cousin to a party with you. You can't deny your cousin's an attractive girl and as the night goes on, the two of you get closer and closer. One thing leads to another and you make your move.

So later that evening, you approach step-mom with your new solution. And this time you're not taking no for an answer. Warning strong themes including use of the "i" word
