I was in my early teens and was going let’s call a bi phase. My best friend and swim team buddy were sucking and jerking each other off any chance we got. My sister is a few years younger and let’s call her a bad girl. She took her own virginity with a hairbrush, smoked at a single digit age already and was just a tomboy. She caught us one night sucking each other and started masturbating in front of us. One thing led to the other and we had our first threesome in the living room. That summer we had threesomes almost every day. I sometimes fucked my sister again after my friend left. We watched a lot of porn together and tried everything we saw. We never even thought of it being incest, we just love sex. My sister is now married and has kids. She is still the biggest closet pervert I know and we still meet secretly. Put on some vintage porn and relive our childhood.
