I have always had a very close relationship with my young stepsister (Beca Barbie). I am aware that she feels more than just affection for me. She wants to fuck me. But I have a girlfriend and I introduced her to her today. My girl wants to like me and cooks us a delicious meal, but it seems the only thing my little sister is interested in putting in her mouth is my cock. That's it, it's time to stop resisting.
