This is a true story.
My cousin and I have never been close since we grew up living very far from each other. At the time he was 20 and I was 19. Everything started when we started texting after he told me he would be moving considerable closer to me. In all the texting we grew very close, but nothing more than friendship grew out of it yet.
One weekend we invited him to sleep over by our house to give us an opportunity to spend some more time together and show him around. We had a lot of fun during the day, going to the beach, drinking on St. Patrick's Day, during the day I could feel a little bit of sexual tension creeping up, but nothing to major. That evening my cousin, my brother and I went out clubbing with some friends. The alcohol was flowing and we got flirtier as the night went by. I would ever so seductively stroke his ass or his body when none of our friends could see. I struggled to keep control of myself.
As we didn't have a guest bedroom, I got out a mattress for him, which we put in my room since there was no space in my brothers room. Luckily my parents didn't mind since he was family. My brother went to bed and my cousin went to sit on his mattress. I was unbelievable turned on, and took my clothes off in front of him to tease him, and put on my nighties. I was looking for any excuse to get him close enough to me, and my heart was racing. I told him he can come plug in him cell phone to charge next to my bed. When he came to stand next to me I looked up at him, put my hand around his neck and pulled his lips in for a kiss. He responded by kissing me hard while our breathing became wilder. I pulled him onto the bed on top of me while we were still kissing. He broke the kiss and looked at me with lust in his eyes. He removed my top and lightly but my neck as he cupped my c-cup breasts in his hands. I moaned lightly to try and not wake the rest of the house. I climbed on top of him and removed his shirt; I kissed his neck and gave him several love bites in his neck while my hips moved up and down over his growing erection.
