Jealous Sister Goes Too Far

Lilli is furious to find out I have been hooking up with a girl she HATES! I knew she would be mad, but, I didn't think she would go so far. So, I dumped Kristin but now Lilly is pissed because I am talking to another girl, I didn't know she was going to get so possessive, but, I am not going to fight with her.
