Tapping the end of the pen on the paper, Dave thought about what to do. This amazing thing he'd found opened up a whole realm of possibilities, and he was having difficulty pinning down anything specific to try.
After a few moments thought, his mind turned to Jenny, still a kangaroo. She'd been very cruel to him earlier, but even so, turning her entirely into an animal seemed a step too far. That said, she WAS something of a pain, and in his view needed something of a punishment.
Carefully he wrote, "Jenny's head and arms are now her normal human ones, although she has the ears of a kangaroo and her arms are covered in fur." He thought this was a good first step, like this she could work and live a more or less normal life, and he could always turn her back all the way later. A slightly mischievous thought struck him, and with a grin he added, "Jenny's breasts are now normal human ones, but will increase in size to E cups." That should produce an interesting effect taken with that fact that as mostly a kangaroo she would have to hop everywhere.
Getting to his feet he left his office and walked down the corridor to the cubicle area, heading for Jenny's one. Everyone seemed to be working normally, heedless of the fact that in one cubicle a woman who was mostly a kangaroo was sitting propped up on her long thick tail typing away on her computer like nothing was different. Dave stared in amazement, even knowing the pen was real, and having seen her as a full kangaroo only minutes earlier, hadn't really prepared him for how strange she looked.
She was wearing a dark blue halter top but nothing else, and her ample cleavage was much more on show than before. After watching her from a distance for a moment, Dave walked up to her cubicle and said, "Jenny, could I have a word in private?" She looked up at him, half scowled, and seemed to remember he was now technically her superior.
"OK, I guess", she said, reluctantly adding "Sir." He nodded and stepped to one side, motioning her out of her cubicle. Rising to her feet with a push of her tail, she hopped out of the cubicle and into the open area of the room, her large breasts bouncing and rippling with every hop. He stared with a slight smile on his face, the effect was even better than he'd expected. He was definitely going to leave her this way for a while.
"My office, please," he said, and she hopped off down the corridor in front of him. He was amazed how naturally she moved, no fumbling or awkwardness at all, but after all he was the only one who remembered that she hadn't always been like this. Entering his office after her, he walked past her and sat at his desk. "Jenny, what you did earlier was not very nice. I would like an apology, and a promise you won't behave like that to me or any of your coworkers again."
She looked worried, but still a little defiant. "Well, it was only a practical joke. No one got hurt." He stared hard at her.
"It was very cruel, and embarrassing. I don't want to see a repeat." She scowled.
"Just because you got a promotion, now you think you can lord it over me!"
"No, but I think that I now have the authority to make you behave a little better at work. It will benefit everyone, even you." She didn't look convinced, and he sighed. Pulling the paper he'd written on earlier closer to him, he picked up the pen.
Glancing up at her, he then wrote "Jenny has four breasts, two more identical ones below her normal pair, and only I will notice." She was too far away to read what he was writing, and thinking he was making notes on her behavior, suddenly became a bit nervous.
"OK, I'm sorry, all right! I won't do it again". He looked up at her, and was a little surprised, even knowing what to expect. She now had four large breasts held in a weird halter top designed to take them, and the sight was pretty strange, although very erotic. She had her arms crossed over her chest, resting between the two rows of breasts and pushing the top row up.
After looking at her for long enough to make her nervous again, he smiled. "Fine. In that case we can forget about it. I hope we can work together without any more problems. Really, I would like to be friendly to you, I don't have any other issues with your work." She sighed in relief, and smiled back, glad to have the issue over. He continued, "You can get back to work now. Thanks. Please shut the door on your way out" Jenny nodded, and turning, hopped out the door, all four breasts heaving, closing it as she left. He grinned after her.
This had possibilities.
