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.

Your wife had no intention of sleeping alone at the conference
A hot submission of @romanianhotwife22
True👍
But you understand why she cuckolds you, and you're just pleased that she still permits you to buy her pretty clothes for her to wear for other men. That way, you can still feel that you have some small role to play in her social and sexual life.
