Today we'll try out what the slave likes more - the dirt from the soles of my flip flop shoes - or the foot sweat from the inside! I've worn these flip flops for so long and my feet soaked the insoles completely with sweat - and the shoe soles are completely dirty! I order him to lick the shoe soles while I'm still wearing the shoes and enjoy how disgusted he is by the taste ... and once the soles are somewhat clean, I take them off and order him to lick the insoles clean as well. Now he has to suck all the foot sweat out of them!
