Kasey said "I want to be a dinosaur not just a plain dinosaur but a anthro T-Rex of my own height and dimensions"
"OK I wish that Kasey would become a anthro T-Rex of her own size" I said.
<Kasey's POV>
I felt a rumbling in her as she felt the changes starting to take shape.
I felt my body slowly begin to grow up to 9 feet or so, a fine size (if a bit large but who will stop me). Grinning from ear to ear, my face took on a few more reptilian characteristics, saurian muzzle feminizing a bit to accommodate plump and pouty lips. My arms lengthened out into toned and shapely humanesque ones as my fingernails grew out into claws. Still with five thick clawed digits on each hand , I clutched my newly shaped hips. Wide and sensuous, they led the eye all the way down my lovely-scaled thighs and calves to three thick footclaws, digging into the ground below me with no effort at all. I slid the new hands over my chest, a voluptuous G at the very least as a grin worked its way across my muzzle as I knew that I can now change my reptilian form at will as Ken gave me free reign over the wish, so might as well use it to my advantage.
"MMmmmm what should happen to you now" I whispered to him as I stretched out my new seductively saurian form.
