Aren't I invited too ?
I hope you will 🔥
When your wife told you that your sisters were taking her out for her birthday, you did get a little worried, because you knew that they had been talking with her about cuckolding you -- but you still are shocked that they have been successful in their efforts -- and you're not sure how to react, but you do know there is nothing you can do to stop it and that your relationship with your wife is about to really change.
The "rules" had been -- when your wife first told you that she was going to start cuckolding you -- that it would not be with any of your friends and that it would always be "just sex", without any romance involved -- which meant not going out on dates with other men. She had started breaking the "no dates" rule within the first couple of weeks, and now it was obvious that she was about the break the "never with one of your friends" rule too. And so -- what is also obvious is that she's right. You SHOULD go back home because it really is better if you don't know which of your friends she's about to start a romantic relationship with.
