I read a story some time ago, possibly here, maybe on that other site, which went like this:
Relatively straightlaced newlywed(?) housewife gets a message that her neighbor saw her walking naked in her home, and it was a turn-on for both of them. Eventually, she ties herself up for the neighbor to come into her house and molest her. The neighbor turns out to be a woman, and she's led down into a neighborhood BDSM club of sorts. Her (female) bosses turn out to be part of it. She's the only one of the ladies in the office prior to that who is not a slave. She gets used as a model for a lingerie party, and more or less loaned out to other club members. Later on, her car breaks down, and she submits to the butch fem mechanic for repairs, but eventually commits herself to the woman. Eventually, it all comes out, and at the end she's (happily) the bottom for the butch mechanic, who is a switch between her and the MC's husband, who tops both of them. Convoluted, but an interesting read because of the descent into submission. Can't find it anywhere despite hours or searches with keywords, tags, etc. I think it may have been removed. Can't remember the author's name, either. It would have been maybe 2018 I was reading it, but it could have been somewhat older than that.
