I can't believe your friends aren't ragging you about this. I was at a party once and my 20 y/o friend got a little cozy with someone who thought was of age (it was a frat party). Turned out she was 16. When he found out, he had the sense to run like hell. He still hasn't heard the last of it from us. 🙂
Seriously though, bad news. Underage. Bad. Sister of friend. Doubly bad.
