It's cold up here lately... -20F (-28C) and Berry didn't want to take off her winter boots... Instead, she wanted to use them on her pets cock and balls! These heavy soled, very rough boots leave some nasty imprints on her pets genitals as she steps all over them. She makes sure to stand in one place several times to really dig those treads in and leave her mark. She didn't need to stomp and jump around, the treads did the damage for her...
