Vague Plot Idea The Third

Back to A/B/O dynamics again, but with age play incorporated. I'd love to see an Alpha Little/Omega Daddy.

That's it. That's the super vague idea as it currently stands. I'd probably do it in an all human setting, no shifters.

Is that bucking genre conventions too much, or does it exist? I just feel like an Omega's nurturing side would make for some super sweet Daddy feels. And more sensitive Alphas are totally my jam right now.

I don't know that I'd include mpreg with it, but I wouldn't be opposed to reading it.

How would you like to see something like this go, or can you point me towards any books that already tick these boxes?
