So I heard that you are disgusted by feet... well, this is completely unacceptable for a sub. You are such a beta loser that you belong down in the dirt beneath me. Your rightful place is under my feet. That is why I will be tasking you with keeping my feet nice and clean, and you will do so with your mouth. It will be so humiliating for you to lick and suck my dirty toes and soles, and it will make you feel so submissive. So submissive, in fact, that you will become addicted to my feet, developing a desperate foot fetish.
