“I dare you to say it’s okay for me to make out with your wife,” my friend said half-jokingly. My wife giggled at this outrageous suggestion. Knowing that she would never agree to be kissed by anyone but me, I called his bluff.
“Yeah, sure - it’s fine by me. If you can get her to go along, have at it,” I said with a confident chuckle.
He went in to make his move with my wife offering zero resistance. After a minute of deep, sensual tongue kissing, he cupped her chin and she started to moan. Several more minutes passed and that’s when it hit me: Their rhythm is too perfect for this to have been their first kiss.
Your wife has been cuckolding you for a little more than ten years, and has been going sexually "steady" with her current boyfriend for about two years. So having her head over to her boyfriend's place for sex on short notice is a common occurrence, and both you and she consider it just a normal part of your married relationship.
