The next thing she knew, Amelia was raising into the air. Suddenly, instinctively, she went stiff and her face fell from utter pleasure to surprise and fear. She certainly wasn’t being used to being picked up like it was nothing.
The human gripped her under her knees and shoulders and carried the little 4’5” trout girl over to a shower stall at the back of the room.
“Have to get us cleaned up before the experiments,” he explained, and set her down on the grate in the stall before hopping in himself.
It was cramped and intimate, which made it more sensual as the human turned on delightfully warm water and began to soak her piscine scales from head to fin. The trout closed her eyes and relished the sensation as the human scrubbed her down with sanitizing soap. She had never had somebody pay this much attention to her form before, and the mammal clearly enjoyed every curve and scale on her body, careful to spend some time rubbing over her big soft tits and tight pussy lips. She felt his cock slap against her back again and giggled. He was far too big for her! So much so she felt intimidated by the mighty member rubbing up and down and small of her back.
Thoroughly and completely cleaned up, the human and the fish rinsed off together and emerged from the stall steaming and ready for round two. But this was not what was to happen.
Tom lead the trout over to the front of the chamber and opened the reinforced glass door. The steel trim around the structure glittered against the poor light.
“What’s going to happen to me?” Amelia asked, suddenly curious and a little alarmed.
“Well, I have several transformations I can run on you.” Tom explained with a smirk, still hard. “I need to test our size change function out.”
“S-Size change?” The fish lit up excitedly. “Like... make me bigger?”
“Oh, definitely. I can make you bigger. Or smaller. I should also try and... stimulate you.”
“Ooh, that sounds interesting.” The trout said agreeably, leaning into her human friend and staring up dreamily.
“We can also reduce your age. Or increase it. Or... if you want to get very drastic, I can run something much more scary.”
“Such as?”
“I could devolve you,” Tom said with a dark look in his eyes.
This made the trout stop and her arousal seemed to wash away in an instant. “Y-You mean... regress me? To a full animal?”
The human nodded.
“I-I’m not sure... I’m not sure I’d... like to experience that. Doesn’t it... it... doesn’t devolving cause an animal’s mind to... to...”
“Which is why it’s very untested.” The human smirked.
The trout wasn’t sure she liked the formerly delightful human’s tone.
