A real cool story line I think. Mom comes home early and catches teen son banging his sister. Mom flips out. Later she talks to daughter and says it has to stop. Daughter says no way, I love his big cock. So mom talks to son to get him to stop. He won't either. Mom sends daughter away for a week. Then gets the kids aunt to try and talk to him about it. Fast forward after son and aunt have talked. The mom,son and aunt sit on the couch and son says he won't fuck sis anymore. Then he tells aunt to explain why not. Embarrassed she tells her sister that the kid won't do it anymore if the mother becomes his sex slave for the week. Pardon me the mom says. She slaps kid and starts to leave. He grabs his mom by the wrist and says in five minutes the deal is off so you better be kneeling in front of me sucking my big cock. Mom runs to her room. Aunt tells nephew he is an awful sonofabitch for suggesting any of this. A couple minutes pass and mom comes back. Says I guess I have no choice. Son stands up and undresses mom. She is naked and he feels her perfect boobs. Ready to suck my huge cock mom? he asks. "Whatever, a cock is a cock. What makes you think you're special." Then he whips out his 12 inch cock. "Holy shit" mom and aunt both say. Son proceeds to get a blowjob and then fucks his moms brains out, even doing her in the ass.
