Recently it occurred to me that in most tfmc stories the transformation to a position of a dominant leather master is almost always reserved to people taking revenge on someone, who undergo it more or less willingly. It seems like the stories where people get transformed into tops unwillingly and don’t accept it right away are pretty rare. So as an expert of the genre, do you happen to know any such stories by any chance?

The only one that’s really coming to mind is one of my favorite pieces by Onix, a part of his Big Mage on Campus series, Part #6: Sloth. Oddly enough, I have a story like this from a commissioner on my docket that I’m going to get around to writing soonish (I hope). 

Still, the “Unwilling Dominator” isn’t a very common fetish. The only place I can think of also seeing it are in stories where the changer is what I call a “Submissive Aggressive” (i.e. in direct communication they take on a submissive role, and in indirect communication they are aggressively dominant–they are submissives who forcibly create tops for themselves) but even in those sorts of stories, the tops aren’t usually “unwilling” they’re just oblivious. 

The more I think about it, the more I’m recalling stories where I’ve seen it used, but I can’t recall names of the stories or even the sites I might have read them on. I seem to recall on being written by AgainstMyWill (this one I think? It doesn’t have any TF though, and I don’t think it quite has the tone you’re looking for). I think there are a few more on MCstories, but you’re going to have to get lucky there, because finding stories with specific elements like that is easier said than done.
