You Set Up and Wait

2 PM

You shouldn't do it to close to the time, or else she might know who it is. But, if you do it too late someone might walk into the stall and see what you left for her. You throw your backpack off your shoulder and open it's contents. None of what you had to bring was particularly big, though some of them cost a pretty penny.

A ring gag, a black sharpie, and a blindfold are all fairly cheap. Getting a pair of wrist restraints with locking cuffs and a fair sized chain running between them, slightly less so. You place them on top of the toilet, along with a note that you will leave a for later.

2:15 PM

You sit on a bleacher near the entrance to the restroom. Now the wait begins. You scan the faces of each female shaped figure who approaches, to see if it's your mystery slut. Your eyes scan their features hungrily. Will she comes?

2:30 PM

The wait continues. You distract yourself with a Superman comic you happened to bring along, but you can't help but peer up impatiently every few seconds looking for her.

2:50 PM

You hide your eyes behind your comic book. There she is! Dressed in a short skirt and a collard shirt. Her eyes scan the park nervously, her fingers are shaking. You hide in the shadows so she doesn't see you. When she stops at the door of the men's room she eyes it hesitantly, before twisting her head around. With you hidden, no one can see her. She pushes the door and enters the Men's room. You smile at that. Her pussy is yours now. Time to check what prize you earned...
