Of course my feet deserve all the attention they can get. Clad in beautiful boots, you may lick them and perhaps suck on my heels as well.
Do you think you can do so with as much enthusiasm as this slave?
And maybe, just maybe you might be allowed to lick my feet when I'm only wearing nylons, but such a treat is not for everyone, of course.
Perhaps you will be able to earn this some day.
Show me how proud you are that you are allowed to lick my feet!
