I have had the privilege of spending time with Andre Lorelei, who no longer resides here, and Carmen Blackwood, who is more or less retired, and it was beyond incredible. Andre has a website, google her full name. Granted my session was a highly specialized kink experience, not what OP is probably interested in, it was delivered with professionalism and enthusiasm so naughty I felt like the ladies were living THEIR fantasy, not me - and isn’t that the absolute best any provider can give us? Andre has added FS to her repertoire in recent years and I can vouch that she is every bit as amazing in that kind of encounter. You might not be able to wrangle in Carmen with Andre if you haven’t seen the latter before, but Andre does work with a number of other local ladies (it is guild/collective of sorts composed of like-minded, curious and refined ladies) such as Ruby Labelle (who posted above and has a sensational reputation), Freya Rose (who is kink-only but I can vouch is beautiful and excellent) and Annabelle Lee (well-reviewed massage-only provider, but I have not met). When she visits she also sometimes has pals from BC along with her, specifically Adrienne Kay (AKA Maya Odelle) who does offer FS and is bloody incredible. Also note, many of these ladies work with each other so it doesn’t all run through Andre.
So whether you want a traditional threesome or something a LOT more wild, lots of great options.
