I was on my way back home from Scotland and stopped at a service area for a toilet call. Going into the toilets I noticed there were several guys standing in the stall soI went into a cubicle and closed the door. I though I might as well sit down so I dropped my jeans and pants and sat down. I then noticed a hole in the wall on both sides ofthe cubicle, each about 2 inches across and waist hight. In the cubicle on my left I could see a hand obviously wanking himself, the one on my right was empty. I leaned forwards to get a better view and the guy then stood up facing me and continued wanking I watched for a good minute then e eased forwards and the next thing his prick came through the hole. I had never seen anything like this beore and didn't really know what to do but I took it in my hand and slowly wanked it. It only took seconds and his cum shot out all over my hand. A few more seconds and he had gone. By this time my prick was fully erect and I neede relief myself so I sat down,leaned back and began to slowly and gently wank myself. I heard the door on my right close and lock. I kept up the slow wank and waited in hope.
