I've written a couple prompts below that fit a similar theme of forced feminization by a warlord through a few time periods, so pick your favourite.
Middle ages:
Garret never cared much for the feelings of others, even when he became ruler of the large swathe of land his father had conquered he cared very little for anyone's comfort. He used fear to rule and took what he wanted. You just happened to be in a town that was being raided and absorbed into his kingdom. You had just turned 18, with the prospect of learning a trade when my men came through.
They had taken you into a wagon handcuffed and carted you back to the large castle I resided in. -> We would pickup here to start the story.
Present day:
You had taken a trip with your school to eastern Europe, thinking you'd be safe, but you couldn't be more wrong. In the midst of visiting a few historical monuments you hear gunfire and men running towards you. You don't remember much, but you sure remember being hit in the head before blacking out. You awoke in a strange place, unable to move your hands apart or more than a few feet from the concrete wall they had been chained to. You also became aware of how naked you were.
Future setting:
It was many years in the future, after the endless wars that plagued earth it had finally calmed down enough but warlords began to take over large territory and anyone who wasn't cooperative was taken away by force. You'd be one of these rebels and taken to see me.
So a few basic scenes, all would heavily include forced feminization, dressing, and rougher anal/assplay and darker themes.
Please be semi literate.
Kinks: feminization, outfit control, blackmail, cock worship, straight to gay, chastity, toys, cumplay, rough anal, dirty talk. (There is probably lots more)
Limits: no blood/gore or toilet play.
