"If You Act Like A Whore, We'll Treat You Like A Whore" - They'll Teach Them To Follow Orders

My stepson and stepdaughter are out of control. He is stuck to the couch all day, every day, and she sneaks out every night to hook up with random guys. This has to stop. I don't care what my husband does to them, but he needs to teach them how to behave. I'm giving him an ultimatum. He needs to show our stepdaughter that if she acts like a whore, we'll treat her like a whore. And if our stepson helps us fuck her like the slut she thinks she is, he might finally find a reason to get off that couch. If they complain, we'll shut them up with my pussy and my husband's cock, but they'll follow every order, one way or the other.
