I've received less for this story than for the vastly less popular Tolkien fanfic. I think that's because it's always been clear where Fidèle was headed. But every single message has been interesting, and it's enjoyable to engage. Like this:
"We the readers are being dominated in ways no story has."
This from a reader who didn't necessarily love the BDSM-heavy chapter I just posted. But s/he saw something I was trying to achieve: the idea that every sexual encounter matters. That it's not just sex. That the principals learn and grow (or recede) and that there's no going back. That's it's *all* in service of character growth and of the story.
I do like a good sex scene. I like it more when it matters.
