Dirty feet cleaner

Now I have a perfect opportunity for you... my feet a little bit dirty... but you don't mind helping me licking it clean, right? My feet are so gorgeous, of course you want to help me. You love my feet so much and love to be useful for me. Open your mouth and start licking them clean! But you are not here to enjoy yourself! You have to lick it 100% clean! Don't be a useless fucking loser, do it properly and start again and again, until I'll be satisfied with your job!!
