Vulnerably Bound Slave To My Sweaty Dirty Feet

Ive packaged the slave in cling wrap - and now hes entirely vulnerable and incapable to budge! Its been a really hot day again and Ive been walking bare feet for the last few hours and my feet got really sweaty and dirty... and hell have to lick them clean now! Hes struggling with the salty taste and the crumbs of dirt... but he cant get away from my feet. Hell clean them heels to toes and suck the toes clean as well. I enjoy seeing him suffer like this and enjoy getting my feet refreshed at the same time!
