Nathan had always had a bit of a weird interest: cock transformation. Granted, he wondered what it'd be like if he himself became a penis, but with Jake eyeing his newly-acquired sheath, Nathan decided it might be interesting if it became Jake's new home. He wasn't sure whether the Chronivac could do that, but it wouldn't hurt to try. And while he was at it, he could add a furry transformation to Jake, as well. Or... maybe not. Having a penis with fur might be an issue.
Nathan thought for a minute, and then came up with an idea, changing Jake's information.
Name: Jake
Gender: Male
Species: Cat
Race: Sphinx
Body: Nathan's Penis
Age: 18
Height: 0.15 m
Weight: 0.5 kg
Hair: None
Eye Color: Brown
Nathan hesitated before confirming the changes, wondering if he was taking things too far. But not wanting to waste this opportunity, he clicked the Confirm button before he could think too much into it, and turned toward Jake to see the ultimate transformation in progress.
"You choose something? I think I feel myself changing." Nathan didn't have to answer, as Jake reached up to his ears and felt them changing, sliding up his head and becoming feline. Jake quickly ran to the mirror to watch his changes, as his face pushed out into a feline muzzle. "You changing me into an animal, too? Couldn't you have been more original? Wait... where's my hair???" Jake's feline smirk turned into panic, as he realized not only that his head of hair had disappeared, but he wasn't growing any fur to replace it. So distracted was Jake by his hairless body, he didn't immediately notice that he was shrinking. Not until his pants slipped off. "What, what's going on? Where's my dick?!" Jake patted his crotch, both relieved and confused to find it empty, featuring neither a penis nor a vagina. As he examined himself, his shirt slipped down his body, also making him keenly aware that he didn't yet have a tail to catch his slipping clothes.
As Jake reached a small height of only 6 inches, Nathan instinctually got up and walked over to Jake, picking him up with a squeak and stuffing him feet-first into Nathan's sheath. Almost immediately, Nathan could feel Jake's feet connect with the tip of his penis, and by extension, Jake himself. He could feel Jake try to pull himself out of Nathan's sheath, but the tugging only strengthened the pull between Nathan's penis and Jake. It only took moments before Nathan's penis overtook Jake up to his tiny waste, barreling him out a bit and repurposing his organs, as Nathan's urethral tract connected to Jake's throat, completing the transformation.
Hanging out of Nathan's sheath was now what appeared to be a tiny sphynx cat furry, trying to push himself out of Nathan's sheath. The struggle quickly stopped, though, as Jake quickly realized that not only could he no longer feel his legs, but he felt anchored somewhere within Nathan's sheath. Nathan watched (and felt) as the tiny sphynx cat pulled himself back into Nathan's sheath, and felt over where it connected to Nathan's crotch from within the sheath. After a few more moments, Jake pulled himself back out of the sheath, looked up at Nathan, and shouted "What the hell did you do?!"
Nathan fell over laughing. What was likely intended to be an angry shout instead came out as a squeaky voice! Jake panicked a bit as the furry tower he was a part of suddenly collapsed, but then became frustrated again as the giant German shepherd continued laughing an almost doglike laugh. "That's not..." Jake covered his mouth briefly, a bit embarassed that THAT sound came from his mouth, but then he recomposed himself. "This isn't funny."
