Cuckold Diet

My mistress has decided I am too chubby. She has decreed I am to go on a diet and a workout regime. She wants it to be as humiliating and public as possible, which is why it's being posted here.

Part of the it is that I still have to cook for her and her man. It is truly embarrassing and frustrating.

Anyone have similar experiences/ideas for punishment and motivation?

Here's a suggestion. You should only be allowed to eat their leftovers, on the floor out of a bowl. Like a dog.

Or perhaps a diet consisting of cum. All protein. Very Atkins.
