Belinda adored the cake. It was so miraculously yummy, and her enormous tummy craved more. She grabbed the cake platter and immersed her face in it, going at it whole hog while her belly and especially her enormous butt-cheeks continued to expand, continuing to enlarge and crushing out through the archway and into the front of the shop.
Mr. TF paused in arranged his new signs for his business and looked and marveled at the wondrous fattycake transformation as an ass the size of a Volvo mooned him through the door. "Oh yes! Yes! Marvelous!" he cried with delight until the Volvo expanded to the size of a Winnebago and then proceeded to become the Hindenburg.
"Ack!" screamed Mr. TF, crushed by the rapidly expanding butt-cheeks.
