Innocent flash gets exciting

I don't have much time to do this but here goes. Last night I was at a gig with my girlfriend and her friend. We stayed in a hotel for the night.it was a double bed with a single bed right next to it. My girlfriend and I were quite drunk so we went straight to bed. Her friend said she was gona read another chapter of her book. In a few minutes my girlfriend was snoring and sleeping soundly. I couldn't get to sleep and was getting bored. I decided to hhave some fun. I pulled my penis out the leg of my shorts and rolled over, moving back the covers as though I was too warm.I pretended to snor a little so the friend would tthink I was sleeping. This started out as a bit of fun but knowing she could see my cock was turning me on and I could feel my penis grow. It wasn't long till it was fully erect. I could hear moving in the other bed. I thought she had finished reading and was going to go to sleep. Then I felt something touch me. Was this my lucky day. The friend gently stroked my cock then I felt heaven when she put it in her mouth. I didn't move and kept snoring a little and she kept sucking. She didn't move much, just sucked on my head and her tongue flicked the under side.she slowly took it deeper into her mouth and before long it could feel myself building up a load for her. As I exploded in could feel her swallow over and over again. Once she milked the last drop she got back into her own bed.I could hear her moan lightly and knew she was masturbating. It stopped after 15-20 minutes. I didn't sleep much, thinking about what happened. This morning I carried on as though nothing had happened and so did she. Think I'm gona plan another night soon and see if it happens again
A true story unlike most on here. Will update more info soon
