Those damned twelve year olds... they just won't stop seducing 45 year olds.

On a serious note though, I once had a ten year old girl (sister of a girlfriend) suddenly latch on to me and try to make out with and grope me. I dealt with it by telling her to get off of me, that she's too young for that, and then I told the girlfriend and their mother to watch her a little more carefully since she's TEN.

Ten year old girl was PISSED that I got her in trouble. We were friends ten minutes later when I agreed to play Pokemon with her. (as you can see, clearly mentally mature enough for sexual relationships...)
