This happened when we were both 18 years old.

End of high school year my girlfriend broke up with me in a very public way. At the time, I was devastated and heart broken.

About a week later, my cousin Sarah came to visit from out of the country. Sarah is a little bit older than me but we're still the same age. Sarah is a very attractive woman and has always been. At 18 yesrs old, she had the body of a woman. Large perky breasts, thin waist, flat stomach and a big behind. Since Sarah lives in another country, we have only seen each other a handful of times, but have always been close (metaphorically). I told Sarah all about my break up and she and I talked about it at length.

One night I got invited to a house party nearby by my group of work friends. They warned me that my ex Rachel would be there and they didn't know if I wanted to go. Sarah came up with the idea of going and said that we should make out at the party, and make my ex girlfriend jealous.

Cue, master plan.

We're at the party, we're drinking a little bit, and here I am with my "new sexy girlfriend." Sarah played the role perfectly. She was flirty with me and played the role of girlfriend really well. We made out a couple of times on the couch and Rachel definitely noticed. She got obviously jealous and stormed out of the party. (That's a whole other story, but trust me, it was very worth it)

On our way home, Sarah having had a few drinks in her was telling me how much she enjoyed our charade and said we should keep it going "just for fun."

We got home, my parents were fast asleep. Sarah grabs me by the hand and leads me into my bedroom on the other side of the house. She plops me onto the end of my bed, and proceeds to unbutton my pants. She reached inside and grabbed my already rock hard cock and immediately puts her mouth around it and starts bobbing up and down, deepthroating me better than my ex ever could.

I took my shirt off. This must have triggered something in Sarah's head because she immediately stood up, and took all of her clothes off.

Once she was completely naked, she climbed on top of me, straddled me and buried my cock deep in her pussy. She rode me hard while I sucked on her tits. I remember her whispering to not worry, she was on birth control. I didn't want to risk it, and when I was close, I pulled out and came all over her chest.

This happened on few other times while she was on her 2 week stay with us. Definitely a fun memory I have!
