The seventh humiliating reveal is one that Mistress has ordered me to do now three or four times. She'll send me off shopping to a lingerie shop where my goal or challenge is to buy her something that she will like wearing and that I will find sexy on her. The first catch is that, even though I know here size already, I need to ask a sales woman for assistance. That part isn't so bad.
The part that is humiliating is that after that piece has been chosen and they ask if I need anything else, I have to tell them I also need panties. If they don't ask, I need to ask them for more assistance. If they just start showing me or if they ask me about her size, I must clarify that they are for me. And if their reaction is of interest, I must also ask them what they think I would look good in for my Mistress.
Unlike what you might read in a fantasy, there is no trying them on and showing them to the sales woman and there is no other play or interaction with these strangers. This exercise is solely to show and experience my submission in a humbling way as well as obedience.
Once I'm home, we'll both model our new additions for one another and then usually, she'll get to experience a nice orgasm that I will give her and I...well...won't.
