Oewh, I'm almost considering a throwaway for this, but here goes. When I was 11 or so I was at a friend. The guy's sister had barbie dolls. I don't remember all the details, but at some point the barbie was undressed and very explicit movements were made with accompanying talk. I remember vaguely drawing on the barbie too. It's been 20 years and can't remember exactly, but definitely went way too far and the barbie was damaged in the process. Anyways, the mom walks in, sees me licking the barbie between the legs and I was shown the door.
The friend was told not to be friends with me anymore and I had to wait outside when we as a group of friends picked him up to play outside or something. Kind of awkward when 8 kids go in for lemonade and I had to wait outside. Ah well, all in the past!
