Knock Knock

When devoted husband and father Evan Webber is left home alone on Father's Day weekend, two young women, Genesis and Bel, knock on his door seeking refuge from a storm. Evan allows them in, and they use his internet to find the address of a party they're looking for. As they dry off, they flirt with Evan and eventually convince him to have a threesome. The next morning, Evan discovers that his wife's sculpture has been vandalized by the girls, who claim to be underage. When Evan threatens to call the police, they blackmail him into having sex with them again. The girls then tie Evan up and torture him before ultimately revealing that their actions were part of a twisted "game" they play with married men.
