Stroking Surprise

I have always loved it when someone is watching me masturbate, it never fails to turn me on. So this one day I was driving in the GTA and I saw a adult video store that offered private viewing for the movie you rented. I decided to park my car and check this out. I had never heard of this before and when I was talking to the owner he told this is a new thing in adult video stores (keep in mind this is going back 15-20 years ago or so). I asked if could see one of the viewing rooms and he said go have look there downstairs and to the left so I went downstairs and saw three rooms each with a tv and vcr a chair and tissue paper. I decided to go home and get some lube and come back. I walked into the store and looked at all the rentals picked one out and went to the counter. The owner charged me $10, gave me a remote for the vcr and said got to room two. I went downstairs to room two and found that someone was in room three but room one was empty. I put the video in the vcr and sat down, I left the door open halfway so someone could peak if they wanted to and then started to take my clothes. When I was completely naked I pulled out my lube and started stroking. I was having a great time when I heard a door creak and realized that the person from room three was watching me. This really turned me on!!! Then I heard someone coming down the stairs, the footsteps got closer and I saw the owner had come down for a little peak. The guy from room three was standing there jerking his cock watching me but went back to his room shortly after the owner had got there. The owner asked me, is it okay if I come in? I said sure so he walked over and stood beside me watching me stroke and then when I let go of my cock for a second he grabbed it and started stroking. I couldn't it I was so horny but this drove me over the wall. While he gripped me I was writhing and squirming as I was getting really close to cumming. There were no signs of stopping he kept stroking me and then I started to cum. The cum went everywhere on the floor, my chest, and his hand. I was really groaning and grunting what an incredible orgasm so intense and when I was finished without a word he just left the room and went back upstairs. I felt so satisfied, that was so awesome!!!
