dude, the only way to find out is if you call and get her to come over. if she asks, think fast, if she doesn't you are good, but think about this. If shit hit the fan you would not get in trouble cause of your age but you would ruin her life. Now she is just fuckin for money, if something happened she would more than likely be a registered sex offender for life!
Yeah but therein lies the next problem.
I obviously can't have her at my house, so I'd need a motel/hotel room, and you can't get one of those till your 18 either.
I'll have to get a friend to get one for me, ahahah.
