Bikini Girls on Dinosaur Planet

When a pair of time-traveling alien beauties stumble across Earth as it was one million years ago, they are confronted by a ménage-a-trois of sex-crazed cave-girls (Misty Mundae, Ruby LaRocca, Lily Tiger) and a land populated by rumbling dinosaurs. It's not before long that the fur-clad lesbian cave-babes get down to some serious grunting and groaning and teach the curious space visitors a thing or two about juicy Jurassic love.
