I love your Game since it can be configured to fit pretty much any sexual orientation and the sounds really help immersion.

But I wanna get to the point: the more "harder" kink-options are added, the more less hard ones should maybe also exist as counter-part.
Best to give you an example (I'm only playing cock-owning males, so I dunno if there are repercussions with any female sexual organs):
there are Upgrade Option for our "little" Demon to have those Cock-piercings (to me it's horrible to even imagine that on the most sensitive part of the body) added to increase cum-production of one's character/Demon.

Since I won't get that one, it would be nice to have more Levels of maybe cock- and ball-size for cum-production increase or even Body-size then. But I think in order for it to be truly a "vanilla" counterbalance they would probably need to be linked to the other ones somehow in order to only offer them when the  player refuses the cock piercings maybe (that would make it not so hard because the players can trigger it with a switch/toggle) and then you can have Hyper-Cock and -Balls with Cum-Output increase, that leaves your prospective partners bulging with cum and not able to move for a while, for example.
What would be hot for a male Demon/Incubus, is also the addiction-level of his cum to anyone cumming in touch with it...having that would very much befit a "Demon" of Lust, methinks...
