I went to the bathroom & when I came out my girlfriend sister had almost fallen asleep, but I was pretty hard & determined to have sex with her, I went back & kissed her until she woke up, I removed her top & sucked her left nipple. She woke up & said what was I doing? I replied with that my girlfriend said it was ok, she relaxed & let me carry on and eventually her legs started to open, she had a dress on so was easy to put my hand up and push her knickers to one side.
I knew I had no condoms as me and my girlfriend don't use them now, I did not know if she was on any birth control but I did not care, My d*ck was throbbing even before I get in her. I said to her I was going in but by then she had fallen back to asleep. I thought I should stop but I was so ready & I knew I would probably never get this chance again. I pushed my d*ck in & started to move up & down on her. I was actually happy she fell asleep as I was not going to last very long, and probably would of been disappointed. I was now ready to cum and was really thinking about pulling out but again I thought I might never get this opportunity again, so I cummed in her. I could not believe it, I had cummed inside my girlfriend's sister pu**y.
After I cummed in her, I got off her, I put her knickers back in place, knowing they would have some of my cum in them as it dribbles out. I then went and got into my bed next to my now sleeping girlfriend, my girlfriend not knowing I just had unprotected sex with her sister.
