Interesting.
So its cool if the wife gets a girlfriend that you can't touch but you don't get anything on the side unless she is involved?
Sounds like that is the exact description of cucking to me just without other penises I guess....
So you're with the woman of your dreams, who plays both sides of the fence, She does her best to pick women who enjoy including you but sometimes she's attracted to ones who are not so inclined. Still no matter what she's there for you focused on ensuring that your and her intimate needs and desires are fully met. She's committed to making your marriage as fulfilling complete and joyous as humanly possible.
But because, from time to time, she engages, in passing, a woman who is simply not into men, you'll throw that away. Okay.
As I said when that ending first came out. As long as she's happy and she makes me happy, and whatever women she finds do not endanger the love we have and share, why should I care? She has everything she needs and I have everything I need (her absolute love and devotion), pretty much nothing else really matters.
Also, the ending pretty much indicates that Alice is more likely to pick a woman who is open to being shared with you. Like I said, absolute love and devotion. Two way street. I don't mind an adjunct as long as the third is secondary in our lives.
