American actress Leighton Meester played nude in That’s My Boy (2012). In one scene, this sexy babe will have hot cowgirl sex with a guy on the bed until they are caught by her father. Well, although Leighton Meester will be nude, we can only see her naked back, because she will cover her wonderful boobs with a sheet. But despite this, the scene still remains very hot and able to ignite everyone’s imagination!
