A rich guy fakes his death, his lawyers contact ex-wives about a last-will inheritance with only one stipulation. Ex-wives need to stay in a house -on an island?- for some days to get said inheritance. (they get individually transported by private helicopter)
The house is very luxurious and fully automated, it cleans itself can cook fancy meals, has a full security package, and is stacked with all the essentials. (There are no other humans in the property other than the victims)
Everything goes without a hitch for the night, but then the house traps its victim and demands obedience in exchange for food and water. (I believe the house heats itself to make the victim thirsty and have her get undressed)
The house makes a puppy girl or cat girl first, a pony girl or a hucow, (there is a barn involved) the last one is turned into a fish woman, -a gold fish?- (not a mermaid)
All help is greatly appreciated.
