I come from a big Catholic family. My next youngest sister is less than a year younger than me. Even though she was younger, she was a bit more on the wild side than me. After I went through a breakup, she got me to go over to her boyfriends place to hang out with a group.

We played truth or dare. My sister and I ended up down to our underwear, then her boyfriend dared us to kiss. We did, and before I knew it we were making out. Every round her bf and the other two guys kept pushing things further and further. After a few other dares for us to kiss and make out and touch, my sister finally just asked the guys if they just wanted to see us have sex. Of course they were like "hell yes".

We did. I was terrified, and didn't know what to do. But there was her mouth on my pussy. Her tongue on my clit. Her fingers inside me. We ended up in a sixty nine and both had several orgasms.

The funny thing is, that night those poor guys were left high and dry as we went home. My sister and I stayed very close after that. We had sex with each other often over the years, shared boyfriends even. Shes the best lover I have ever been with.
