It's not too new, but she does have a scene or two in the brothel, currently. Doubtless we'll add more content for her, but it was only recently that we'd seen people respond positively to her: initially we saw mostly silence and negative reactions to her oral-focused content.
Fun fact. I'm straight. But I play this game both because it has lots of scenes to unlock/collect (and I love collecting, metroidvanias are my favorite game type) and because my fetishes right now are corruption and domination (they change every few months), lol. I can ignore the main character being male, no problem. Same for futadom world. I was having a lovely argument on a plot hole for a couple pages there recently, lol.
Which is why I absolutely
love the Mouth Fiend's entire scene set. It tickles both my fancies. The only one I haven't watched yet is the one in the brothel, from what I was reading from the wiki (boy that wiki needs some work. It has almost nothing in it). The same goes for the goblin sneaking into your tent while you sleep. I like the 'notice and wake up, then surrender' oral domination scene.
I like tons of the written content in the scenes, too. Very intricate and well done. Though some feel a bit 'meh' without images at the moment

I have a good imagination, but visuals help immensely with enjoyment.
Edit: Are there any more scenes along those lines? Most seem to be 'bang and walk away'. I'm also curious if the unicorn has an oral scene. Even wearing diamond plate and battle skirt, the damn thing murders me in two to three hits (22-32 whopping damage per swing). Way before I can seduce and kneel. I unequipped all my armor and died in the same number of hits as well, so there may be something wrong with the unicorn's programming.
