Did I help my wife cheat

here is the real deal, she has been fucking the woman and the man behind your back for over 6 months. You are the johnny cum lately in this game. they were getting bored with her and the sex was dropping off. she didnt like that at all so she invited you in on the threesum to improve her odds of keeping the sessions alive. you did the right thing by having some sex with the hottie wife because , you would have gotten nothing otherwise and your wife would have just continued with the threesum until it faded away. so my answer is no , you did not allow your wife to cheat , she was already cheating on you. she didnt invite you in for your pleasure , you got some action to benefit your wife. this is the real dynamic of wife swapping . it is not wife swapping at all, its husband swapping. now you know what really went down.
