You're younger sister needs a tutor, and you've stepped up to help her pass her classes. You're studying in her room, and she's getting frustrated with her math work. You suggest you move onto something else, and she chooses biology. Your hot little sister tells you she knows all about the human body, how to reproduce and how to get pregnant. You tease her, she can't know everything, right? She gets annoyed, and she tells you she has always wanted to be impregnated, will you breed your barely legal little sister?
