You couldn't be happier that your wife FINALLY agreed to cuckold you -- although, now that it's happened, there is a small part of you that feels anxious about what this might mean for the two of you, and for her, in the future. What seems undeniably true is that the genie is now out of the bottle, and your wife is enthusiastically embracing cuckolding you.
And the truth is -- it's how your wife wants to spend those "special" nights too -- to make it as clear as possible to you that you are no longer the most important man in her life.
