Mistress Wildfire and Mistress Diana have dirty boots, they put their slave straight to work in cleaning these, with his tongue.

After he’s been put to use as a boot cleaner, he can then be put to use as a foot rest, as the ladies put up their spiked boots on his back.

They then instruct him to lie on his back, more boot cleaning with the tongue, while his cock is teased with heels in chastity.

The slave is really being put to use to work for those boots.
