>>819773695I fell asleep yesterday before finishing. Starting from the beginning:
In 2008, I was 12 years old and my sister was 10. She is a natural 9/10, has light-brown hair, pretty athletic and a slightly bitchy attitude. Honestly, up until this point in our lives, we didn't really engage in incestuous activities besides really mild experimentation like peck kisses. We usually got along ok.
Anyway, her best friend was a girl in her school year, also 10 years old. Pretty tall for a girl, long silky brown hair, cute 8/10 looks, VERY athletic and slightly developed body. She very obviously had a massive crush on me too. Every time she visited our house for a playdate with my sister, she always spent an unusually large amount of time hanging around me and talking to me, and we ended up getting pretty intimate. Back then, I was a bit of a "bad boy" who always got in trouble at school for misbehaving, knew all the swear words and enjoyed sex and violence. I'm pretty sure sister's friend was attracted to me with stuff like that in mind.
Anyway, one day sister's friend comes over for a sleepover. As usual she hangs around me a lot. Me her and sister played a round of Mario Party 5 together, watched some TV, various other stuff.
Then later in the afternoon, sister's friend and i start talking about porn and sex with my sister not around. We watch a few videos from my collection in my room and the atmosphere starts getting hot. She starts asking all kinds of questions, looking up to me as the older, more knowledgeable source of information, which I answer to the best of my 12 year old knowledge.
