After finally going through the final step of ascending to her destiny as a fertility goddess, Scootaloo presents her new form to her fellow crusaders. Basking in the attention like a cat to sunlight, Scootaloo flaunts her new-found powers, easily doubling the size of her balls before their eyes. With a smirk, her rump bulges with new thickness as the pegasus grows a foot or so taller than her friends, the new goddess’s plump pregnant belly jiggling along the way.
 
Scootaloo could feel their exasperation, the pitter-patters of their drool hitting the floor, their noses flaring on contact with her intoxicating musk, their awestruck gazes beaming onto her new body. She let out a shiver of excitement, not that she could help it, she was impressed by her changes as well. And she knew it didn’t have to stop there, for as long as Rainbow was growing inside of her, Scoots could easily just siphon off her size for the futafilly’s own desires when the foal got too big. With powers like that, she’ll just have to be content with being perpetually pregnant. Maybe she’ll make her cock bigger next.
