Show Some Manners: The Owner of the House Gets to Fuck the Guest's Stepson

We love traditions in my house. My favorite one is that whenever we have guests, I get to fuck their stepson. Don't worry, I'm not selfish; in exchange for their stepson's dick, they can also have my stepson. We can even do a foursome if they want - the more the merrier. All I know is that nobody leaves my house horny. I'll take care of everything and give them a night even hotter than my dishes.
