Showing off SeXStoRY

Like I have said, I love to show off in public. I was going through a drive thru the other day....jacking off of course. I got to the window to get my food and there was a hot black chick there. She made my cock hard as a rock!! I lifted my hips up just as she was handing my drink out the window. She looked down, saw me stroking my dick and smiled from ear to ear. She stood there watching until my food was ready, then passed it out, staring and smiling again. I tried so hard to cum for her, but I couldn't. And I have tried going through there again, but I haven't seen her again. I wish I could see her again...anywhere...to stroke it for her!!
