The other week I was in a hotel and I'd bought a porn magazine to wile away the hours. Naturally this got me horny and I sat in the window seat and flicked through the pages. I stretched out on the seat and undid my pants and eased out my dick which was very hard. I slowly stroked it and then lifted my ass off the seat so I could push my pants right down. I was pumping away absorbed in the images in the porn mag and knew I would soon blow my load. So I stood up and stepped out of my pants and went and got some tissues.
As I got back to the window seat I looked over at the building opposite which was only a few yards away across an alleyway. I thought it was an empty office block but as I stood there slowly stroking myself I saw that there was someone at the window which was at a higher level than mine so they could look down on me as I sat on the window seat and see exactly what I was doing.
I couldn't tell whether the figure was male or female and I thought what the hell and kept on stroking. Knowing that I was being spied on (hopefully by a pretty secretary) really turned me on and I felt myself building up again. I stood in front of the window, the magazine in my left hand while I pumped my dick with my right till, with a wonderful sensation, my jiz came shooting out all over the glossy pages. Whoever was watching, and I could still see the shadowy outline of them, must have seen everything so I hope it turned them on, as being watched like that made my session hotter than usual.
