My roommate has a girlfriend and she practically lives at our house. One night she brought a friend over and both were going to spend the night. I knew her friend as she would come by the house every so often. She was a beautiful girl and had a great body and perfect breasts.
I was in my room trying to sleep when I saw her come into my room in her underwear. She drew back the covers to my bed and slid down my boxers. I was completely surprised and instantly thought I was dreaming. She just laid down right next to me, causing me to get an instant hardon. She said 'I guess your awake' and smiled.
Still a little surprised I asked 'What are you doing?'. She said 'Don't worry about it, just relax'. She took off her bra and grabbed my cock, starting to jerk me off. I began to caress her breasts and make out with her. After a few minutes, I knew I was going to cum. Sensing that, she asked 'Are you ready to cum?'. I said 'Yes' and she began to stroke even harder. I let out a little moan and ejaculated all over her. We kept making out and fell asleep laying next to one another.
