I had a friend in high school like this. A very attractive gal but a TOTAL drama queen/attention whore. She hooked up with a friend of mine who was sort of a male counterpart to her personality, always having to be at the center of every conversation and constantly demanding attention. In a way I guess they were perfect for each other.
Anyway, she eventually broke up with him and tried to win my sympathy by concocting some story about how he'd gotten her pregnant and she'd miscarried and buried the fetus in the woods. Seriously mentally disturbed girl. I have no doubt whatsoever (plus my friend's testimony) that she was outrageous in bed though.
I also have no doubt to this day that she was trying to get my sympathy to drive a wedge between me and my (then) girlfriend at the time to "get back at" my friend by f*cking my brains out. Which, stupid me, was too honorable to let happen. Of course my girlfriend at the time who I was so chivalrous towards eventually ended up cheating on me. Go figure.

. Yea, I was an idiot. I bet it did piss my friend off to no end that I saw through her ruse and her ulterior motive and kept it purely friendship though. I was probably one of the few guys she couldn't control or manipulate and I'm sure it drove her nuts. Heh, heh, heh. . .
Wonder what happened to her. Probably O.D.'d or something by now I guess. . .
