"For today's assignment we will have to take a detour from the office. There will not be room for you to transform here" Jenkins explained briefly before ushering Christina out of the door almost as swiftly as he had welcomed her in. There was no further explanation offered yet, but on balance Christina would prefer to be getting larger than smaller yet again.
After a brief walk she was lead into a large field. A late middle aged man who looked like he was probably a farmer nodded at Jenkins and led his guests through to a tall and very spacious barn. He unlocked it, let Christina and Jenkins inside, doffed his cap and left.
Christina scanned her new surroundings while she had the chance. The place was empty but the stench of various different creatures intermingled in the air. It was obvious that transformations were common here and it wasn't long before she discovered what her next one would be.
"You are going to become a horse today" Jenkins announced as if it were a treat fot her. It seemed this was considered one of the more glamorous species to be turned into "I realise it isn't quite as spotless in here as in the office, but could you please undress. There is a bench where you can leave your clothes."
Reluctantly, Christina disrobed. Not omly was this environment much chillier than the central heated office (and to her embarassment Christina felt her nipples hardening as she made her way over to Jenkins) but the floor was already making her feet feel dirty. It would be her hands soon too as she adopted the all fours position required for this transformation.
Wordlessly, Jenkins locked Christina in his gaze once more and she felt her body begin to change. This time though she was getting larger, stronger, more athletic. Her legs and arms, which were quickly becoming legs as well, became slimmer as they were covered in light brown hair, the same colour as her own. However they felt stronger and were easily able to support the rest of the body as it grew longer and bulkier. She could watch the bizarre sensation of her fingers and toes fusing together into hooves before her neck began to elongate and her face pushed out into a long muzzle, while her ears became pointed and rose to the top of her head. Finally, and for the fourth time that week, she felt a tail unfurling from her buttocks and drooping down as far as her knees.
"What a beauty!" The farmer smiled as he walked back into the barn once the transformation was complete. He couldn't resist stroking Christina's back and giving her a pat on the rear as he examined the new form of the cute young woman who had entered his barn a little earlier.
"Indeed she is" Jenkins agreed "Now you can bring Christina's lucky new owner in here to meet her"
