Abella Danger and Mandy Muse shake their big asses and trying to get their sweat on, with the intention of not only getting a good workout, but posting sexy selfies on their Thirstagram accounts as they get hot and steamy. And it just so happens that you’re there, too, so why not join in with them – especially once their bare asses pop out of their yoga pants and on goes the oil! You don’t have to imagine double-stacked fat asses anymore; you can EXPERIENCE them.
