JAMIE
Jamie stood by in barely-contained excitement as the mechanical arms in the bathroom telescoped out of the walls and removed both his and Carla's clothing, expertly disrobing them since, as bovine as they now were, they were completely incapable of doing so themselves. His arousal was plain to see. He wanted nothing more than to make his way behind Carla and do her proper, like a bull and cow should.
His mind had devolved pretty far, barely holding on to his human intelligence, and in this state of primal mating urges, that human aspect was even less prevalent.
"Unnnghhhhh..." he moaned as the robotic hands struggled with his slacks. "Taking tOOOOO loong..."
CARLA
Carla had not devolved mentally as far as Jamie had, and it wasn't entirely clear why. She wasn't particularly smarter than him before, but as of now, she was the superior intellect. She patiently allowed the robotic arms to undress her, feeling some annoyance at how silly Jamie was behaving. They had all the time in the world, why the need to rush it?
Somewhere, in the back of her mind, she had some faint understanding that things weren't always like this, but she couldn't pinpoint exactly what was different or why.
Fully undressed now, high pressure shower jets began cleaning her off. It felt good, glorious even, to be clean, to be free of those soiled clothes and be as she was intended to be.
MEANWHILE...
From a secure room a good distance away from the action, a lone figure watched the proceedings from a videoscreen. The whole process had gone observed, from the moment the test subjects entered the "restaurant", to their transition from hominid to bovine, to the moment right then, with them being disrobed and cleaned.
"It worked, I can't believe it worked," the lone observer said as the door in the back of the room opened, a "waiter" stepping in.
"It's exciting, isn't it? To think that those two had once been human beings, not even half an hour ago... the formula was a complete success, and we owe it all to you. Without your funding, and the two test subjects you managed to provide for us, this never would have been possible."
"I just... I can't believe that that's my Carla, that that's... can I talk to her? Alone? Without that idiot Jamie trying to... oh, ew, he just..."
"Couldn't contain himself, clearly. Didn't even manage to get the pants off," the "waiter" finished that particular train of thought. "And I see no reason why not. She is yours, now. Both of them are."
"Right... right," the observer stood up, and slowly turned around. "I'd like to talk to her now, please."
"Surely. Right this way."
