My friend lost a bet and is my slave?

My friend lost a bet to me, so now he will be my personal slave for a week! I want to make him wait on me hand and foot and make me feel like a princess! I am only interested in him as a friend and nothing more! He wanted us to hook up if he had won the bet! I need ideas for making him feel like my total slave. I also want to torture him with my feet (since he hates them)!!! How should he serve me???
