My girlfriend and I returned from a walk and wanted to humiliate our personal slave girl. We walked for a long time and our feet were very sweaty. I didn't change my socks for a long time and they even turned black from dust and dirt. We ordered this idiot to remove my socks with her teeth and stuff them into her mouth. The slave girl licked the sweat off my feet and my girlfriend's feet. Indeed, why should we wash our feet when our devoted slave girl does it to us.
