Amy thought a moment. "No, I actually like this a lot. My body transformed into yours. My throat being your anus. It's a very big transformation for me. I couldn't possibly ask for more. The taste is not good, but I don't want you changing that, either. I want to taste your poop for what it is."
"Well, what about control? All you can do is move your head, talk, and... release my poop. Can I make it so we share control of my body?"
"You can, but may I request not? Your body is unfamiliar to me. Feeling you move it with such familiarity is really fascinating. And besides that, I think it's a fair tradeoff. You do all the moving for me, and all I have to do in return is spit out your poop." Amy giggles.
"I think it could be more fair."
Amy nods. "If you want to make changes to yourself, I won't stop you. Your body is yours, and so is the Chronivac. I don't want to hold you hostage in your own body."
Jeff pulled the Chronivac out from its hiding place, and began to reinstall it on his PC. As it did so, he began thinking of ways to think of improving Amy's situation. He looked at her resting her head on the stool beside him, his eyes following her neck to his hips. He pulled off his pants and underwear. At this point, they only served to keep him decent. With Amy the apatosaurus now acting as his butt, he no longer had to worry about a dirty behind sitting on his chair. But what he really wanted to see was how they were conjoined.
As he noted before, he no longer had any apparent butt cheeks. His hips simply extended out behind him as an apatosaurus neck. Where his hips and her neck joined, though, was a little jarring. Her thick blue skin quickly transitioned to his pale human skin. It made her look very out of place. Maybe he could use the Chronivac to make him more like an apatosaurus. Help her feel more at home as part of his body.
The second issue is that she, is a she. Jeff has no intention of changing Amy to a male, of course. But he did wonder why the Chronivac gave him a female apatosaurus when he himself is male. Should he make himself female to match? Amy didn't seem to mind being attached to a male.
And lastly, of course, is that she is now his butt. There is no changing anything about that. Not until she decides otherwise. But there's gotta be some way to improve the situation. Maybe make it so she can eat, too? That way she'd be able to taste more than just his poop. It's also the least-gross solution he could think of. But if he really wanted to be fair, maybe he needed to endure the grossness, too. Make it so he can taste what she tastes. Or, repurpose his mouth like he did with her's.
The Chronivac pinged. It had finished reinstalling. Time for Jeff to put his late-night imagination to work.
