A huge part of the appeal of this fetish is how amazingly, fiercely physical and indulgent these beauties are.
They can gorge themselves on more food than even an army could stomach, kick every single ass between the North and South poles, then break for lunch and a nap.
The thought of being intimate with a monster like that is so unbelievably thrilling to me. I just want to cuddle and caress her big, bulging muscles, then fall asleep on her massive mound of a gut, lulled to sleep by the sounds of her belly working over her meal.
That may just be me, though.
