Shit that's nothing ...I know of girls in THAT age range who are into 3 somes, lesbianism, and having guys tag team them...
Its no wonder they are burned out on sex by the time they 18
I have a teenage cousin who lived with me for years (from age 14 to 16) and she had her friends over ALL THE TIME and they would "tell me " these things...
lol, ok so they would do more than tell me ...I would usually just leave the house, otherwise I might give in to their temptation
