I only saw the trailer, but I remember it had a scene was two guys, backpacking or hitchhiking stay at a woman’s house. All three sleep in the same bed, and one guy wakes up to his friend having sex with the woman. The guy having sex tries to convince his friend to join, and I think he even grabs his friends hand and tries to put it in her @**. I want to say it was a Scandinavian movie.
