Bootlicker- Lick That Clean

I want this stupid slave to clean my dirty boots by munching them. His tongue licks every crumb of filth from them. He does as I say and just the way I like it! Only once he has munched everything clean can he sniff my socks, but will he ever get the job done? He takes my order earnestly though and licks and licks and licks, just how I want him too.
