Its seems to me that this was a girl who wanted to be "cool", liked by guys and not considered a "prude". She wanted to fool around or do who knows what. Her desire to be "cool" stopped her from making correct, prudent decisions, if her desire was truly to not have sex with the guys. She already admitted that two guys asked "why wont you do stuff?". Her going into the bedroom with them, after already knowing what they wanted,in my mind, says she was afraid of not being cool and essentially consented to be "cool"(or is completely lying). She probably in hind site realized she had done something she wished she hadn't and maybe really didn't want to deep down inside. Her story was shaky and its obviuos that her parents pushed this prosecution.
