This story is centered around a the POV of a male who simulates a home-invasion where he keeps his sister blindfolded and trains her with some sort of crop-touch system. They later enslave her friend who has been kicked out of her home, and there are hints and clues that their parents kidnap and train 'slaves' of some kind as well because they find their secret training room in the house and during their calls with the parents it indicates they are away because of one of these hunting trips. I'd appreciate any help y'all can give me.
