You and your wife have two children -- twin girls who are now 18. Although your wife has been cuckolding you for several years, she has kept that fact a secret from them -- until now. You're very nervous about how this coming weekend will go, with her boyfriend spending the weekend at your house, with her, and getting to know your daughters. You know that your wife is very hopeful that they'll like him, which would make it easier for him to spend a lot more time in your house with her in the future.
The weekend went even better than your wife had reason to hope it would -- which meant that, for you, it was a shamefully humiliating experience from beginning to end. Your wife's boyfriend and your daughters hit it off almost immediately, and you were put in the position of having to serve dinner to the four of them -- your wife and her boyfriend and your daughters -- as they chatted and laughed together -- including all of them laughing about what a loser you are. Perhaps the worst part for you was being bossed around by your wife's boyfriend, and by your daughters, and being teased by your daughters about the fact that you were going to have to sleep in the guest room while your wife and her boyfriend slept together -- and would be having sex together -- in the main bedroom upstairs. And then by the end of the weekend, your daughters were begging your wife's boyfriend to move in, so that he could really become the new man of the house -- since it was obvious (they said) that you could never be in that role again.
The next day -- after your wife's boyfriend had left -- you expected life in your household to return to "normal", but you quickly learned that everything was different now. Your wife told you -- in front of the girls -- that she wanted you to continue to sleep in the guest room even when her boyfriend wasn't there. The way she put it was that sharing a bed with you would feel like she was cheating on HIM -- a comment that elicited giggles from both your daughters, who were now calling you "cucky" instead of "dad", and who continued to boss you around the way they had over the weekend.
Feeling very insecure now, you sensed that obeying them, and your wife, was probably the right thing for you to do now, and that evening -- after serving the three of them dinner -- you learned that you were right about that -- when one of your daughters asked your wife if she planned on divorcing you. Your wife smiled and asked both girls what THEY thought she should do, and they said that as long as you were as obedient as you'd been all weekend, maybe it made sense for your wife to keep you around, even if her boyfriend moved in.
Then, the next evening, your wife's boyfriend dropped in unexpectedly. You answered the door, and then had to just stand to the side as your wife greeted him with a huge hug and kiss and as both your daughters ran to greet him too. In fact, they could hardly contain their excitement as they asked him if he'd decided about moving in. With a big smile -- he told them that, yes, he'd decided, and that yes, the decision was -- yes! They both gave him a big hug, and then one of them turned to you and said "Isn't that GREAT news, cucky!". All you could do was to hang your head in shame and whisper yes.
