You looked across and saw that the female officer had started to change. She was oblivious as her ears became pointed and covered with brown fur. Her fingers also started to merge into solid lumps while a tail grew under her clothes.
You then began to strain as you felt the weight on your back getting heavier. You figured that Mark was going through changes similar to his colleague's. You tried to get their attention but neither rider took any notice.
The officers’ bodies kept growing as they gained more muscles to suit their changing skeletons. The weight soon became unbearable so you let Mark fall to the ground behind you. You looked back as Mark got to his four hooves and neared the end of his transformation. He was now black from head to hoof and was quickly bulking up with muscle.
You tried to run but only managed a few steps before your body stopped itself. You strained against your own body but you couldn’t move a hoof. Your panic increased as you picked up the unmistakable smell of a stallion nearby. You looked back and your fears were confirmed: Mark was now a full horse.
You watched, helplessly glued to the floor, as the black horse’s penis slowly flopped down towards the floor before it started to harden and release some precum from the tip. You tried to look away but your eyes remained transfixed on the growing organ. You unwillingly began to swish your luscious tail as your vagina began to moisten in anticipation.
No! You should have known that this was going to happen; the very same thing happened to you for Christ’s sake. You snorted in frustration as victory slipped from your grasp. Then you whinnied in terror as you felt Mark stick his muzzle between your legs. A feeling of dread crept over you as you prepared yourself for what was to come.
