To tell the truth, I thought there´s plenty of stuff like you suggested around already. Serious humilation ´n rape. And torture too. Depends on your point of view though.
I refuse to write or keep stories like that because I believe in consensual bdsm. Even though I see myself as a strong character I can´t and won´t tolerate stuff like that. I´m may be aroused by it sometimes but get sick if I give it a second thought.
But I can recommend you a story which is published as both,
book and Comic in Europe (don´t know about the US) if you really get going by stuff like that.
"Marie Gabrielle de Saint Eutrope"
She´s suffering greatly of humilation, torture and rape during a ten year stay in a catholic convent. The story takes part in 18th century france.
A personal question: Are you a male or female undergoing this hormonell treatment? And what for? Just to look better?
I´m just curious. Physical alteration in any form is highly interresting to me.
