I do my sport at home. As outside it rains too much to go running, I do it in my living room running in place. I'm just wearing my runnings and my t-shirt. I have the bare ass and I trotted on the spot. My buttocks rock in every sense, every stride my ass bounces, and at times I do squats to stretch my ass and muscle my buttocks and thighs.If you like to see me doing sports naked, come tell me It will please me.
