Looking for a forced feminization story

[sirskipperdoo]

Good day,
I read a story probably a couple years ago that I can't find with anything I have tried searching both here or through Google.
Basic story: Man is a lawyer or works for a law firm. Has to go to a recently deceased man's house to find some sort of paperwork regarding the estate. Get's locked downstairs in a room that forces his actions, all automated.
Forced feminization
Non-consent/reluctance
Bondage
It seems to me that the introduction mentioned something about being written for some sort of challenge, but I don't remember what it was.
Anyone recognize this story? Thanks.

Is this the one you're thinking of?
The Legacy of She-Devil

No, that's not it, but this one looks interesting, too. Thanks

Does anyone recognize this? ...bump...
The part that intrigues me compared to other stories is that there is no interaction with anyone until near the end. It is a mind game as much as a forced fem.
