Teddy Byers is wondering if there's a way he can last longer during sex. So he asks his stepfather. "I can teach you how to control your orgasms," Mr. Byers says. "How are you going to do that," Teddy asks. Todd wraps a blindfold around his stepson's head and says, "You can't cum until I tell you that you can cum." Then he ties Teddy's hands to make sure he doesn't touch his cock.
Did you miss the Byers in their last fuck session? Mr. Byers catches Teddy smoking and takes him over his knee to teach him a lesson. Then he fucks him to drill his point home. But this is actually the fourth chapter in the Mr. Byers and His Son series, so you've got some catching up to do.
