The guest girl deserves special treatment, especially by her boyfriend. This is the thing that I don't get. How do Anna and Alex know this couple? I mean you just don't invite strangers into your house and attempt a foursome. Seems like you'd have to know people to an extent before that. It's different then a sex party, this is their house. But the thing is, Anna and Alex are home so much and we've never seen these people before, so when did the "get to know" the couple? Are they our hunting for swingers in the morning when I'm asleep?
