I don't remember it but I have a much older female cousin. She would always babysit us when we were younger and I had same-age female cousins. What the older one would do is tell us to get naked and she would make us straddle each other then kiss each other. I, apparently, used to be forced into a closet with my same-age female cousin and be told to French kiss her and pinch her tits. I was around 5/6yo when this happened so I have absolutely no recollection of it at all. The only reason I know this actually happened is because one time I guess I started crying during the middle of it. It was during a family BBQ. All the parents were outside drinking beer and had the older cousin babysit all of us (like responsible parents do) inside. So I start crying and they run inside but don't see us anywhere. The older cousin kept making excuses until she finally unlocked the closet to which my Uncle (who was there first) was shocked. He said we were fucking in the closet and I was crying and my female cousin was all red and sweaty. So they beat the shit out of the older cousin and threw us in a bath and washed us off. For years me & my female cousin would not interact with each other because of inside jokes from the family. It was mostly whispers or light-hearted jokes but my Uncle was a loudmouth and every time he saw us together he would shout at us, "Hey [Anon]. Don't fuck your cousin! BWAHAHAHAHAAHA" and think it was the funniest shit ever.
I used to have sleepovers with a Slut Stacy from my other side of the family. She was bisexual and started experimenting sexually very young. During our sleepovers I'd ask her about her experiences and she would go into graphic detail. I used to like the stories she would tell of her going to her BFFs house and they would lez out together. At 13yo (I was 11 she was 2 years older than me) she said that one night her BFF was really horny and they were watching a movie so she got some whipped cream and put it on her then ate the whipped cream out of her asshole. Shit like that makes me die that I never got to do stuff like that. I used to touch myself underneath the blanket, hoping she wouldn't notice, as she was telling these stories then I'd jack off like crazy when she fell asleep. I was just producing cum around this time and she always used to make fun of the stains on my shorts and underwear. At the time I never knew what she was talking about until I was around 15/16 and my Mom was teaching me how to do my own laundry then I realized why she was teasing me all this time.
