Finally I can chill on the bed after walking for a long time in my boots. Dirty soles in bed, however, are not allowed, so I call my slave and order him to lick them well until he has cleaned all the dirt and dust. He is doing a good job while I completely ignore him and get distracted with my smartphone. When the soles are clean I check his tongue which is now black: he did a good job so I can now allow him to smell my feet in pantyhose. He takes off my boots and sniffs deeply as I rest my feet on his face while I keep ignoring him.
