You have resisted the temptation to walk home through the park for a few days but your mind has been drawn back time and time again to the events in the toilet. Every time you think of it you've had an erection and on a couple of occasions you've taken yourself in hand in the office toilets until your sperm has jetted into the bowl. The recollection of the experience is tremendously exciting.
Eventually you cannot resist it any longer and it is a gloomy day when you once again make you way to the partially hidden brick building. Your heart is pounding and you keep your hands in your pockets to hide the trembling, but your excitement is intense as you enter the half dark interior.
You go straight to a stall and unzip yourself and take your penis out, your not completely flaccid but already wet penis, before looking around to see the place is empty. The anti-climax is tremendous and you feel all your expectations drain away. You stand there for a minute idly masturbating in the hope that someone else might appear but you don't hold out much hope and never get more than half hard.
You are just about to pack up and go when the sound of a loud sniff draws your attention to the two stalls opposite the urinals. The door of one is closed but the other is partially open and you move along the stalls to peer round to see if there is anyone in there. From your new position it appears to be unoccupied but what you can see is a hole in the dividing partition about two inches in diameter and about crotch height.
You realise that the sniff must have come from the occupied stall and with rising excitement you enter the vacant one and close and lock the door. You sit on the seat and bend forward to look through the hole. What you see is an eye looking through at you so you pull back quickly. You are nervous at being recognised but want to see what the other person is doing so you sit still and wonder whether to leave or not.
As you are thinking, you see a finger just tap the edge of the hole and withdraw. When you don't react it happens again so you gingerly bend forward to look again. This time there is no eye. What you see is a mans erect penis sticking up from his hairy pubis and his balls hanging below. He has his trousers and pants down and is sitting turned towards the hole so he is clearly on view. His foreskin is pulled tightly back and in the dim light you watch as he starts rubbing his cock up and down.
Suddenly you are really aroused and struggle to get your own penis out without taking your gaze off the action next door. His masturbation stops and you see his body moving then his eye again appears at the hole. He is wanting to see yours now and waits for you to react.
You stand up and move out of his direct vision then lower your trousers and pants before moving back into his line of sight. You stand close enough to the hole so that he isn't able to see much of you apart from your genitals and start rubbing yourself. You know he can see your swollen glans and the precum liberally coating it and a surge of it leave a long string hanging down towards the floor.
