They are separated into those two categories. The settings just need some tweaks.
The Orphan is glad to hear that, despite the slimes in both her ears. Hopefully the next update will bring some order to orgies, so they're crazy but coherent.
As for the multiple penetration, it's proving controversial.
As for the more extreme stuff and advanced sex techniques, instead of playing with toggles and sliders in the game settings, perhaps a story-driven descent into depravity could be built? Let's face it, lots of sex events happen matter-of-factly, without a proper build-up or agency: just have enough promiscuity and awareness, so one day you'll get two cocks in the same hole, grind enough deviancy, so one day you'll walk into Alex' farm and fuck a horse... Instead, those MCs brave and perverted enough to seek uberkinky sexual adventures in this dangerous Town would have to consciously work for it. Of course, some events would happen randomly, so the non-cons aspects of the game and dealing with stress, trauma and control would still be there, but it would be up to the player if they want to explore this thing or that further.
So for example, Leighton's spankings could awaken masochistic tendencies in the MC, but it would be up to them to decide if they want to explore this and use the Adult Store + corrupted Sydney to practice their masochism. Similarly with multiple penetrations in the same orifice: gangbangs, brothel work and tentacle encounters could lead to discovery of such possibility, but the PC would need to actively study some lewd literature and practice with toys for some time while masturbating to be able to stretch their holes enough to accommodate two or more appendages.
This way, the players who detest this stuff could easily avoid it as it would be impossible to just walk into such activities. The perverted players, on the other hand, would need to work for it, which, with new intermediate scenes and activities, could make grindwork much more exciting. Leighton's spankings would gradually get more and more severe in intensity as the maso stat grows and the Headmaster could react to that in less mechanical fashion than what we have at the moment. The hardened masochists could use the 'Ask' action to ask for more or harder spanks and the spanking minigames would rely on the PCs pain threshold, which if exceeded, would result in severe trauma and stress penalty plus loosing a lot of maso stats. So it wouldn't be, as it is at the moment, just taking the beatings and physical abuse until they love it - it would be a measured, guided process, where experiencing significant pain combined with significant arousal increases masochism, while too much pain with low or moderate arousal decreases the same trait. Also, this could affect the PCs personality in such ways that serious pain-sluts would be leaning in their available courses of action, seeking situations that would be potentially hurtful, while those players who valiantly avoid any painful and sexually charged interactions would not even know about the existence of SM-specific scenes.
Similarly with multiple penetrations...
