Are there any other authors that write stories about female humiliation.
I have some, although humiliation is only part of those stories. None of them would be in the BDSM category.
Some are on SOL, but the one with the most humiliation is on ASSTR called "Wife Pays for Husband's Shortcomings." I don't remember "Daddy's Little Girl" (also on ASSTR), but it's tagged "humiliation."
My stories on SOL are written better than the ones on ASSTR (IMO). "The Preacher's Wife" has some humiliation, but the SOL version is better written than the version on ASSTR. Also on SOL, "Teacher's Nightmare" has humiliation, as does "Mind the Teacher." So does "Deceiving my Mother - Part 2."
ETA: Probably my most humiliation stories actually are no longer available. They used to be on my own story site. The two that popped into my head are "Stuck up Neighbor" and "Butler in Charge."
