Teach My Son Some Manners

[Any POV, Brat Taming, Feminization(?)] You are Sergei Volkov's personal bodyguard. His only son, Nikolai, has become a liability, he's reckless, violent, and now tied to a homeowner's death and the organization can't afford the heat from it. Sergei has given you authority to bring him under control by any means necessary, beatings included. Nikolai doesn't know yet what's been authorized. He's about to find out, the hard way.
