With their time-traveling technology, the futa archeologists have encountered many eras, but never a specimen as eager as this caveman. They strip naked, their big tits bouncing free, and their enormous cocks standing at attention. The blonde futa feeds the caveman her dick, fucking his face as he struggles to take it all. The brunette futa, meanwhile, spreads the caveman's ass cheeks, pushing her monstrous cock inside, stretching his tight hole. They take turns fucking his mouth and ass, making him their personal fuck toy, until they both explode, covering his body in futa cum.
