I am looking to know about a movie I saw on IFC. There are 3 main characters. Twin brother and sister and an American male who is staying with them while the parents are out of town. The sister loses her virginity on the kitchen floor to the American male... and some how or another it leads to the brother and sister messing around. I can't remember much about this movie, but I do remember the sister tries to cook and she burns it... and they run out of food.

The Dreamers (2003) (http://www.imdb.com/title/tt0309987/)
