Pure fantasy?
My girl has a body that seems perfectly optimized for just storing fat healthily.
I on the other hand have a body that could not gain enough weight before my system gave out. Forget death feedism, I wouldn't have enough time to savor my newfound obesity before I dropped off the mortal coil.
So my one hope is reincarnation, and some sort of "fat karma."
In this life, I've helped someone to enjoy their own constantly growing obesity. So my fantasy is in the next life, I get the same. A girl who is constantly pampered and stuffed by everyone around her until she reaches a world record for the most massive person. Stable and healthy... but also so gigantic she needs all her loved ones to help roll her out of the house.
Ideally a *thing* that barely resembles a human woman anymore, only with a lovely happy face.
