Pumagirly's wearing her white sneakers when she steps on the "cock board" as she calls it. Her slave's dick's sticking out of a hole in the board and she steps on it immediately. Her slave's in a lot of pain but she proceeds to walk over his cock again and again. She makes sure to put her whole weight on his dick to inflict the maximum possible pain. In the end she even stubs a cigarette out on his penis - ouch!
