Showing off my shopping spree went wrong

Mistress Fiona gave me a shopping budget to buy some more slutty outfits. I'm showing them to her and I'm telling her why exactly something is slutty for me. She agrees with almost everything. She started laughing with the dress I kept as last. It was a mistress looking dress, she immediately showed me who is in charge and made suck a dildo while I tried to dress as a mistress! I'll never be in charge of her OMG!!
