I actually think a lot of porn in general is focused too much on feminine pleasure, or that we're supposed to be pleasured by it. Porn tries its absolute best to keep the guy as silent and as out of the camera view as possible, most male porn stars barely even look like they're enjoying the scenarios they are in. Even mind break, which is supposed to be a rapey genre, is focused more on convincing the girl that she enjoys sex, rather than actually having the sex itself. I think this is why the ''ugly old guy'' genre is popular for some people, it forces the guy to be an active participant the scenes and due to the genre are made to actually give the viewer feedback on how good they're feeling.
JSK's games are kinda rare, at least from what I see from the porn I view(a lot of it) where it has a route where the guy is the one being pleasured and the girl isn't the sole focus, or if the guy is the sole focus is more of a tool to convince the woman that deep down she's a horny slut. I mean if I'm watching porn and they're trying their absolute hardest to keep the guy silent , out of camera, even if they have to do ridiculous positions to only show the girl, how does that convey to me that I would be enjoying it if I were in their position?
Vanilla genres tend to suffer from this as well, but that's an entirely different can of worms.
JSK's games can be approached from any angle, sex for pleasure(rape end). Sex to convince the girl she's a horny slut(lewd ends). Sex where the girl either maintains a form of agency, or is the dominant one(subordinate ends), and the normal Honorable guy has an encounter with a girl and they both love each other route. He has a somewhat decent variety in body types. I'm not sure if this is intentional but he doesn't seem to try to make outstanding scenarios, rather uses common scenarios that we all love and enjoy because he's not trying to write a novel here. It's just a quick, hour or so long game with a toybox of nice things for everyone.
I don't really think the girls are full of much personality, they're an archetypical anime character in their respective roles and that's not really that big of an issue I think. VN's are more focused on story, while having sex, so they're not really as free with their characters but these games in particular shouldn't be held to those standards imo.
