To no one’s surprise, we finally found out that all four people from the Flintstones TV show are swingers. We see Fred Flintstone sitting on his fat ass while Betty Rubble blows him. We gotta give major props to Betty because she a) gives a great sloppy blowjob b) arches her back like a true slut c) doesn’t forget to pull down her panties and finger-blast her leaking pussy. Who’s taking the picture, BTW?
