With each passing day, Fluttershy's beauty only grows greater. Rarity, fine-proportioned mare that she is, can't help but be jealous of her friend's swelling sex appeal, with each new cup size or pant-fitting only driving her curiosity and lusts higher. When Rarity finally presses Fluttershy on the secret of her burgeoning curves, though, she discovers a source more erotic than she could ever have imagined.
