Your day continues as does the feel of the Coachman's whip. As you are walked to the stable, your stall and given the evening rations it's hoped all is forgiven.
Morning brings a sudden jerk awake.
The mares are gone, you are alone in the big box stall. A noise from outside the stall door opens to see two men with lasso's and the original Doctor who gave you the injections.
"You pony volunteer are in trouble! You tried to contact your Wife as she passed by in the crowd! This was forbidden in your contract as we know all too well. As such you are relieved of all duties as a regular pony inside the Park." explains the Doctor as two men place lassos over your head and tighten the noose.
"I am sending you back to the Research Farm, but with this added special injection. Due to your continued tries at keeping contact with humans and family it is a demand in the contract that you be treated with a ruthless form of Stallion Behavement Formula. This injection will for the most part make you a true stallion all day and every day for the balance of the contract. Like mares in heat you will feel much the same but in a male sort of way. As the Formula reaches it's peak of control your animal instinctive drive for to mate will rip or just wipe away all human reasoning. In as much you shall continue on under the contract but in a new and more hardy of form. The second injection and one each per day for the next full month will grow your body from pony size to full horse size. This effort will be painful at times but once you reach the preferred form, a Morgan stallion's form, then the mounting of horses can commence. Over the remaining contract you shall be at stud as a prized Morgan purebred with certian human qualities which the foals and their owners will no doubt find quite delightful." said the Doctor as the second injection pokes down into your neck.
