Ty feels the first big changes happen to his body - his feet strain at his shoes. Part of him still vaguely hopes his clothes hold back the changes by simply constricting his body into a still-human shape.
But the shoes burst and his sock-covered foot grows out the front hole in his shoes. He scrabbles for purchase in the wooded area, and claws rip out of the socks and into the ground.
The girls are in full-on laughter now, pointing at him. "I can't stop it!" he shouts. "This isn't me!" But his actions betray him: he thrusts again and again into the tigress.
The change reaches his ears, and they cover with black and white fur. He feels a little bigger now, and he's not sure what will go next - his shirt or his pants.
