Nice Sleepover

My story happened two years ago. One of my friends held a party at his house, of course the whole gang was there to party with him. After much fun and celebration we decided to sleep-over in a friend's house. It was five of us who stayed over. Three slept on the flour while I was sleeping with one of my friend in a double bed. We both stripped down to our boxers and got to bed. Everyone seemed to fall asleep pretty fast... after 5 or 6 minutes I felt something rubbing my ass. It was my friend that was pumping his dick against my back. I liked the feeling so I did not say anything. After a while, my friend might have noticed I was awake because he asked me if I liked it. I did not know if I had the answer but I simply said yes. He then said, why don't we both take our boxers off and do it to each other. I agreed and we both took turn, rubbing our uncovered dick against the other back. Feeling his uncut dick sliding against my ass was awesome. This lasted for about 10 minutes, after we each turned back and started to masturbate our own dicks. This night was awesome!
