Mummy's Friends, Mother-In-Law Sissy (Mother-In-Law' Sissy Short Stories #10)
Honey Wells

Proud of himself that he was able to persuade her he was the right man for the job, things turned strange when he had to sign a contract and strip down to nothing.
Austin wasn't going to be just serving drinks to his Mother-in-law's wealthy friends, he was going to be dressed up in a filly pink French maid outfit, covered in make-up, sissified to the max and thrown to the wolves.
These events were special, they were designed to remind the women that they were top of the food chain and men were only there to be humiliated and used.
Austin was certainly going to get used in every conceivable way and worst of all...he might just end up liking it.
