I live and work by a shopping center. It's an indoor strip mall. I work near by too, so I walk to work everyday and cut through the strip mall.
Occasionally I'll stop in the TJ Max and use the bathroom. The bathroom butts up with the womens bathroom so I'll hold my ear up to the wall and stroke it, waiting for a girl to relieve herself. I don't know why but hearing a girl pee really makes me cum. Once I know there's a girl in there peeing I really start stroking and always bust before she's done peeing. I always nut all over the floor and rub it into the floor.
