I little bit of both, I guess. I can understand playing "hard-to-get" with some characters; teasing some interactions, especially with heavily fetish-based characters, is all right. The problem is what you are pointing out: some characters (like Pricia and Naomi) are receiving scenes very often, while others barely have any (sexual) content when the game is almost reaching 50%.
Don't get me wrong: I love TON, and I think NLT is one of the most reliable and hard-working devs out there. It's just this is starting to get a little bit frustrating. And that's a pity, since both models (especially Naomi) are hot.
Also, yeah, the lady is nuts. The bald cuckold who passes for her husband is not the sanest (or the smartest) person on the island either, though. He reminds me of Pep Guardiola a little bit, only slightly less full of shit and more likeable.
