Yes -- That Was What You Had Agreed To, But You Do Wish He Wouldn't Come To Town Quite As Often As He

Everyone at the resort knew your wife was fucking him.

You and your wife had gone camping, and while hiking the first day of a four-day trip you ran into an old fraternity buddy of yours who was hiking and camping alone. He joined the two of you, and almost immediately he and your wife really hit it off. By that first evening, it was almost as if you weren't there as they sat together by the campfire talking and laughing and kissing. When you quietly left to go to bed, your wife offered you a quick "good night hun" then she crawled into his tent with him.
