You're a Feet Slave to a Tennis Champion

I am a tennis player who is married to a famous tennis champion. I am relaxing after a successful game when I notice you, a slave. I cannot believe my eyes; you used to be my boyfriend who broke my heart, so elegant and refined and now you're just a slave. Therefore, I want you to take of my tennis shoes and massage my feet which you do as you have no other choice. One thing leads to another and I have a surprise for you. My boyfriend and I have decided to buy you. You become our legal property. We do the same with your crew so that you can be a crew of slaves and serve us. I teach you all of the rules that you have to obey, such as only speaking when autorised, always following us and cleaning our toilets. My boyfriend finishes his game and you take off his shoes and massage his feet too. I make you fetch a tennis ball a few times and show you how you will be whipped if you do not listen to us. You tell us that you love us and beg your mercy. We are very proud of you.
