Thank you, SamuraiSam! We're doing our best to make it great, I've personally fapped a thousand times to it already.
Yes! We have a sex dungeon already planned... if you so happen to fall into the witch's hand. I don't know how hard you want us to go, but I can say for sure fisting is among one of the fetishes.
If you want to make a list of what fetishes you'd like to see in the game comment here or post on our reddit: https://www.reddit.com/r/VesperLustAndHunger/
I'll ask our perverted programmer and story-teller... (myself), to implement at least one of them.
