You should check out chainofclovers' fiction -- she writes almost exclusively femmeslash, and she's big on slow courtship, nuanced relationships, and "older" women (whatever that means). She's good at being adorable without being sickeningly sweet, and she's also very, very careful about how she handles consent in sex scenes. Not sure if you're into her fandoms (The Devil Wears Prada and Doubt), but either way I'd give her stuff a chance, because she's also very talented.
