Shoe Licking Foot Rub

What a surprise, one of my slaves has pissed me off. Forgetting his place and speaking out of turn - unacceptable! So I decide to punish him by getting him to lick the soles of my shoes clean - Ive been strutting around the dungeon a lot today so goodness knows whats on there! I make him ensure he does a good job, cant have anyone slacking around here! Having spent quite some time licking the soles of my shoes clean, and sucking on the heels like a cock, I decide that I want a foot rub. So I order slave boy to carefully remove my shoes and show his humility and adoration by giving me a good foot rub.
