I dont, really, especially that one.
Porn writers writing exclusively things that get their motor running is a good thing. It's how great porn is produced. Churning out stuff just because other people want it gets you content that's dry and tasteless.
A writer has to be able to write from multiple perspectives and multiple fetishes, otherwise they just don't exist. They have to.
'Anal' in practice is anal catching, anal pitching, domination, submission, switching, and can encompass the vast majority of sexual interaction (not counting consequences) because what's important is the interactions between people/things/events and the contrast therein. 'Anal' is just a genre within a person's comfort zone.
Games ghat focus on a specific fetish, or a small group of fetishes generally have way better sex scenes than games that try to have something for everyone for that exact reason.
This game gets around that by having a fairly wide group of writers. But I'd personally rather each writer stick to what they enjoy and are good at than try and satisfy people who aren't into the content in the first place.
I feel like that's a bit of bias? There's a [long by NL's standards] scene in NewLife where the guy takes advantage of the woman by getting her drunk and knocking her up, but the writing is, in total, like 15 sentences. But in the writing, there are small hints of what's going on, and if you view the scene, you see your clothes are being taken off without you being aware. It's such an incredible concept that I consider it one of the best scenes among any games, but again, like 15 sentences of simple writing.
The quality of writing for a fetish isn't what's important here. That scene, or mostly any of these that we're talking about could be written for any fetish. The problem is, the interactions and scenarios in which the characters exist don't make sense.
