His eyes itched and if he could have seen them he would have known that they had turned a bright yellow. His hair was growing thicker and he could see that some of it was in varieties of gray. He could feel his canines grow longer and sharpen, pressing against his lips. His hands tingled now and he looked down to see his fingernails start to lengthen. They continue to lengthen before thickening and curving into dark claws as the same happened to his feet.
He felt a sharp pull at his spine and rushed to take his shorts off. He still wasn't convinced that he was really transforming but as his tail burst out, fully furred and mobile what was left of his doubt faded into nothingness.
His attention shifted to his ears as an invisible force like fingers, pulled them into points. The 'fingers' continued to work as he felt them move his ears up on top of his head and push them larger, more triangular, and deeper. His nose itched and he subconsciously licked it with his tongue. It took a minute to register with him that not only was his tongue much longer than it had been but his nose was cold.
He was taken away from this thought as his face began to push out and he could see his now fully furred muzzle begin to form. He suppressed a strange urge to howl, as the muzzle continued working its way out until it reached its intended length.
His feet which had felt bigger earlier were now visibly lengthening growing skinny and forced him to stand on the ball. His big toe moved away from his toes, shrinking to almost nothing as it went.
