Christmas party when I was 5 or 6. This younger girl wanted to play "grown-up" so she lead me to the den, closed the door (key part), threw me on a sofa, and then attacked me with sloppily french-kisses while biting most of my mouth.
I didn't see her again until the next Christmas party where it was repeated. Never saw her again.
What the hell happens to kids like that?
I had the same experience when I was 7 or maybe 8, this girl had maybe 12 I think, she took me to a dark room to kiss, then she took her panties off "to play a little more"... but when I saw her pubic hair I was surprised by it, so she just told me... "Oh you don't have it yet ? well it will grow up!", then just put her panties up again and kissed me once more time and we went out to play with the other kids....
I was too innocent at that time... but I never saw her again... I wonder how she ended being so precocious.
