Mike and Ethan are two conspiracy theorists who have developed a bizarre idea: they believe their stepsisters, Khloe and Sofie, are actually reptilians! All the signs are out there: they use skincare to hide their moulting, they can bend their legs in ways no human can, and they are constantly rubbing against each other to keep their cold reptilian bodies warm. The guys have been documenting Khole and Sofie for a while and are pretty sure that they got them. After interrupting a steamy situation between the girls, Ethan and Mike pressure them to come clean about their true identities. To prove they are not reptilians, the horny ladies decide to push things over the limit and give them the ultimate proof of their humanity: a nasty fuck session! By having sex with them, Sofie and Khloe expect to show them how human they really are. Will that be enough to convince the guys?
