Mareth is supposed to make the residents a bit rancid and horny, but she became so simple-minded so quickly it only makes me think that her slutty history is riddled with terrible personality disorders. It almost seems like she's experiencing a panic attack with that dick slapped against her face at page 4.
It won't really matter in the long run, since all hentai eventually go down the same route, but it'd be a better intro if the girl, even if "slutty", would not be practically shellshocked if she has a cock against her face. I mean, she IS supposed to have 22% of lust resistance, and she's already at 70% lust without doing anything. Who even gets to such a state against the starting Imp? These guys are going to be pretty much done for within a dozen pages, won't they? <:
