You thought this vacation would improve your sex life, so far it's only improved your pussy-eating skills and your ability to withstand blueballs
Your wife always got looks from other men in public and that aroused you. Encouraging her into being with other men was your destiny to be a cuck. Now when men smile at her they don't know what you do. She is available. But some men will engage you both and you encourage that. She deserves other men.
As a guy who is so aroused by other men's wives there is a sense of delight and power when you enjoy one in your bed. Even a friend's wife. You were surprised by a friend when he informed you that his wife agreed to play in this way and that she was turned on by you. How wonderful you thought that she was essentially handed to you so easily. And she has an allure that makes any man hard. Being a friend, you assured him she would be in good hands and brought her to your cabin in the mountains. She was so nervous but you weren't. You were on a mission. Your friend craves to be a cuckold and she needs a man. Mission accomplished.
