Goddess Sonia and Mistress Ayn want their boots cleaned but their sub doesn't know the proper way to clean them - it's with his mouth of course - but he needs instruction. He isn't very good at paying attention so he does a shoddy job of cleaning Goddess Sonia's boots. He is then instructed to clean Ayn's and he does better, with a little motivation of having their heels pressed into his nipples.
