Everything about the chores doesn't make any sense. First, why is it an option to do chores for other girls without any reason for it? Why would you want to spoil them? Secondly, I did yard work every time since I wanted to keep my word, but apparently that isn't enough for Sara. Doing chores is seriously retarded in the first place. Yard work, laundry, doing dishes. These are fucking everyday activities that don't need to be mentioned, let alone gate sex scenes behind them.
Also, there is absolutely no reason for MC to be subservient to Alex. Is jacking off in the shower a crime? No. This is the dumbest fucking reason to become someone's slave. Secondly, he is essentially saving their entire household. Thirdly, he pretty much comes on to a windfall of property, contacts, and power which is way out of league for little old Alex, but she has a video of him jacking off in the shower... oh what can he do?
