As I sat there slowly wanking the guy who had just come in to my right put his finger through the hole and made a beconing motion. I was dubious but thought in for a penny ect so I stood up moved closer to the hole. His hand wriggled through and looking down I saw and then felt it take my prick in a tight grip. I whinced and he tightened his grip pulling me hard o the wall. Then he eased off and slowly moved his hand back and forth getting me harder than I have ever been before. He then let go and his mouth came to the hole. He whispered, \"fuck my face\" I eased forwards and pushed through feeling the warmth of his mouth close round my shaft. His lips tightened aroung it and he just stayed still. Remebering what he had said I began to thrust in and out ot the warmth of his mouth my full 6 and a half inches only held back by the thin ply partition. I was getting close to cumming and my prick was throbbing as he suddenly began to suck hard as well as back and forth fast. That did it. I pushed hard up to the wall. I wanted all my prick deep in his mouth. He continued sucking and working on me until my legs began to shake as at the same time my climax hit me hard. I had my hands on top of the wall holding on as my cum spurted out time after time and he sucked harder and harder drawing every last drop from me then holding my prick tight in his lips drawing back to take the last dregs of cum. He stopped as I slipped out of his mouth and I stood still holding the top of the wall until I could breathe normally again. Then I sat down again until I had fully recovered, dressed and set of to walk back to my car. A guy was standing outside just lighing a cig\' He stopped in front of me and said \"If you want more, here\'s my address\". I have seen him seveal times since,so more later.
