When the reader of your erotica story is actively disappointed by the end of a multi-page alchemy lesson because it was so interesting, you know you're doing something amazingly well. And of all the stories I've ever read where I was exceptionally interested in the characters, story, or world-building, yours have far-and-away the best actual sex scenes. Looking forward to more.
Good so far, but I truly hope there is, at a minimum, an initial defining moment for your MC. Thus far, for a champion, she's extremely weak-willed, passive, and lacks anything resembling initiative. That said, you're extremely good at world building, interested, but cautiously so
I can't believe she didn't tell the alchemist about the Potion of Impossible Insertions. Especially right when giving her the ingredients from that encounter. Wasn't seeing if she could make more of the potion at least part of the idea of collecting those?
I am pretty convinced that either you ARE a RWBY fan. Or you just have the most coincidences possible. Sofia's physical and combat style similar to Weiss in your other story. You have people with animal traits in this one and one of them is a lamb girl named Fe. If you aren't a fan of RWBY there is a Lamb Faunus girl named Fiona who her friends call Fi.
