I honestly think if she was written to be just be "a rampant whore doing rampant whore things" the PC interaction wouldn't have been included in said scenes. They only play to that fetish. The Berwyn scenes I'll give you for the whore being a whore but the merc and lizard scene I can't see it being written with anything else in mind.
"Not a bad cumdump you got here, pussy." The douchebag of a mercenary smirks over at you, squeezing a handful of Cait's hair as he uses his knot to bludgeon her pussy gaping wide. "If I ever give up being a mercenary, I'll have to come to steal her from you — this is grade-A meat... if she could pop some kittens out she'd be great. Try to make a few kids before I take her away from you, yeah?"
