Men in Love (2010)

Charles and Whitney are a close-knit heterosexual couple until a friend, Alex, comes to visit. Whitney lets him move in with them because she thinks he will be a good influence on her husband, who has a tendency to cheat. But Alex wants only one thing: to abuse Charles. He drugs him to rape him. After that, Charles reveals himself as a homosexual, until a pastor explains to the couple that he was under the spell of a spell cast by Alex.
