This is my first time submitting a story here. This was one of my favorite masturbation sessions.
This happened about three years ago now. I had started dating a girl (whom I am still with actually). At the time I was 27, she was 18. So there's a bit of an age difference, but nothing too bad. Anyway, we were very much sexually attracted to each other.
One morning we were laying in bed together and we started talking about masturbation. Now I'm not prudish by any stretch but I never really spoke to any of my girlfriends about that. It was always private. She was curious about how often I did it, how I went about it, and if I cummed a lot from it. The more we talked about it the more turned on I was becoming. Finally she asks 'Can I watch you?'
Of course I said yes, after all we had been naked together plenty of times so it wasn't like it was a new thing. Still though, having never masturbated with an audience I was a touch nervous.
I pulled down my boxers to reveal my already rock hard cock. I began stroking it... she never took her eyes off it. I did it slowly at first then gradually sped up a bit. Precum was oozing out of my tip and down my shaft, it made for an excellent lube.
Meanwhile, with her eyes still fixed on my bulging cock, I could see her rubbing herself from under the blanket. I could hear the wet smacking sound as she went to town on herself while I continued to pleasure myself.
Suddenly she bucked a bit and let out a very satisfied moan, all the while still focused on my jerking. I felt myself getting ready to go over the edge. 'I'm gonna cum', I moaned. I was just about to when she surprised the hell out of me.
Just as I was about to spurt she grabbed my cock and took the head and pointed it between her breasts, I let out a very loud moan as I shot what had to be the biggest load of my life onto my girlfriend's chest. Even more to my surprise when she looked up at me she smiled saying 'I love cum!'
She asked me how I liked being watched. I smiled and told her I love it.
To this day she'll still ask me to put on a show for her. Sometimes she lets me finish on her, sometimes in other places.
