Another Work Quickie

It was a bit of a slow day at work today so naturally the mind wanders. First it wondered to the amazing sex with my girlfriend last night and then to my fantasies. So a few minutes before my afternoon break I searched through some porn on my phone getting hornier by the minute. Before long I nipped into the porta john and pulled out my hard cock and began stroking it slow then fast then slow until I spurted hot cum. If only I could have been fully naked, maybe next time.
