Foot Eating Slave Locked In The Smotherbox

Ive put the slave in the strangle box - and embark by standing on his face shortly. But hes not only getting his face trampled today... hes going to gobble my sweaty feet while hes trapped in the box! I order him to eat all the mess and sweat from my foot feet and he obeys - not that hed have any other choice with his head in the strangle box! Again and again I touch my foot soles over his tongue and enjoy how hes suffering. And of course, he has to suck all the sweat from my long toes as well - and lick between the toes! Maybe I should make it a little harder by standing on his chest with one foot while hes coerced to lick the other one?! :-D.
