This Has Become A Very Common Weekend Routine For You And Your Wife. Her Boyfriend Comes Over Either

This has become a very common weekend routine for you and your wife. Her boyfriend comes over either Friday or Saturday evening, and then stays until Monday morning. They like having the house to themselves during this time, so it means you spend a lot of weekend nights in a nearby motel, and you know not to return until you see that his car is gone, and that is often late Monday morning -- because they both like to have a final "go round" on Monday mornings before he leaves.
