I don't know if you can really call the game a demo.
It's more like just early access, game is being developed along the way and you get to see the progress almost every week.
Femboys have been requested before.
And Arc doesn't seem entirely against it either, proven by how he added it as an option in the kink polls that go by ever couple of months.
But also it doesn't do that well in the polls. It's a rather controversial kink.
Arc might probably give a better answer once he does his rounds.
