Fluttershy remained silent, but she couldnt fight the smile steadily creeping over her lips. She knew that Rarity had already lost. If the unicorn had bolted for the door the instant she had secured the amulet, maybe she would have had a chance, but now, she was completely at Fluttershys mercy.
 
Fortunately, Fluttershy reflected, she had no mercy.
 
Help me, Rarity groaned, spreading her stance even wider. I cant… I dont understand! Why is this happening?!
 
Gritting her teeth and squeezing her eyes shut, Rarity made a desperate effort to remain on her hooves. Her puffy legs trembled, but her body continued to fill out with every passing second. Her haunches were simply massive at that point, the base of Raritys tail undoubtedly lost between them. Her bloated sides threatened to obscure Fluttershys view of her flanks. The pegasus noticed that her cutie mark had been stretched out as well.
 
Pleased with the display, Fluttershy idly wondered if Raritys belly would reach the floor before her legs gave out.
 
Please, Fluttershy! she whined. Go get help! Somepony has to know whats wrong with me!
