Haha, funny.
If the captured, high-willpowered girls don't comply immediately (it's part of the "breaking in slaves" thing in this game), just go buy a rope, tie them up, and have your way with them as much as you like. That'll probably show them who's the master.
Also, I've had to take it easy with not making stuff like that too obvious (non-con, girl's age, rape words, etc) as I first planned on taking this the Patreon route. Since that's cancelled and I'm doing full SubscribeStar, the master-slave interactions will open up more gritty/realistic choices further down the road - while still not cancelling the "loving master" approach others appreciate.
So, please try this trashy shit again in a couple of months.
