It was a five of diamonds. Written on it in black permanent marker were the words "Tyrannosaurus Rex Legs" in block lettering.
The change was practically instantaneous, as Jenny's butt and hips were the first things to grow, and grow indeed they did. They ballooned out over double their original size, filling with thick fat and muscle, and destroying her skirt and her sock. Strangely enough, it didn't affect her waistline, but she did feel herself leaning slightly forward at the hip. Her legs grew longer and developed a tyrannosaur's knee structure, filling out with the necessary fat and muscle. Her feet exploded out into three clawed toes, and her skin from the waits started to turn a leathery, dull green. Finally, she felt a tail shoot out from the base of her spine, ending the transformation.
She was absolutely speechless. She'd turned into half of a tyrannosaurus rex! And she could feel that her pussy and anus had reformed themselves as well, almost becoming cloaca. She could feel a strange heat building up in her crotch, and she knew she needed one thing: SEX!
