There's definitely some pretty good ones out there. It's difficult to wade through the trash, though. Especially now that 90% are AI generated cuckold simulators.
Modded Skyrim. Imo I think its way better because modded its still an RPG game but it has sex. Its not a sex RPG it can be as much of the focus or as little of the focus you want and that makes it better than many many sex games
It's why I bought House Party. I don't give a shit about the social deduction aspect (although I do want to actually play the game at some point), I just like that I can use console commands to make everyone walk around naked and have an orgy.
The vast vast majority of porn is either completely contextless or any just plain trash. People prefer porn when they have some kind of connection to a character with actual personality.
Also these mods are also porn, free, and on the internet.
