Jeff the penis was confused. Earlier that day, he was an 18-year-old dude. He had received the Chronivac in the mail. After sorting through its capabilities and downloading various transformation packages, he not only turned himself into a female, but also created a copy of his conciousness in his new vagina.
It was not hard to figure out he was the conciousness that wound up as his vagina. The giant fingers that rubbed him moments after his transformation helped define his new body. His mouth had become vertical, his nose had become the clit, and he had this giant cavity that went through his body. He was also blind and deaf. He had also set the Chronivac to randomly choose whether he could smell or taste. And he could definitely taste. His insides tasted not bad, but also not something he'd want to taste all the time. It was his decision to become his own vagina, though, and he knew he'd be staying one for 24 hours. He can get used to it.
Before long, he could feel his host moving around. It was quite a sensation, feeling this female's legs swishing around his body. Moments later, he also felt cloth on his face: a pair of underwear. And then the feeling of walking while being covered with underwear. It was almost as though they were all rubbing in that Jeff was nothing but a vagina, now.
It wasn't long after that Jeff experienced his first purpose as a female's vagina. He recognized the feeling of needing to pee. And moments later, it came out of his urethra, right under his former nose. It was at this point that he discovered not only how rancid pee tasted, but the Chronivac had also given him a sense of smell. He could smell the pee coming out of him, as well as the toilet bowl just below him. Overall, this was not at all a pleasant experience. He would have gagged if that wasn't basically what his body was doing.
And then came the toilet paper. He had never needed to wipe his pee as a male. But this was another part of the vagina experience. He could only imagine as this giant blanket of toilet paper swooped in and wiped him dry. The texture of toilet paper is a little different when it's this much bigger than you. It didn't feel bad, thankfully. If it did, women probably wouldn't wipe themselves dry like this.
At this point, he wondered if maybe he should've set the timer's duration for something short. 24 hours is a long time to spend as just a vagina. Getting peed out of, having no movement on his own... Actually, he hated to admit it, but he kinda liked it. It was awful and would definitely take a lot of getting used to, but the point is that he's a vagina. He's SUPPOSED to have pee pour out of him. He's SUPPOSED to be mercy to the whims of his host. He also gets to be the most intimate part of a woman's body, and his host is completely okay with this. So, outside of experiencing child birth, might as well enjoy the full experience. It isn't harming him.
The next 40 minutes or so were spent with very little motion. That's another part of a vagina's life, apparently. There's a lot of not doing anything. Jeff decided he could use the downtime to think about what other transformations he could undergo, though. Maybe an animal? Maybe a piece of clothing. He could be the underwear covering the vagina instead of the vagina itself. Would he go back to being male when this is over? Actually, when his conciousness merges back with the host, he'll have gained experience from being both female for 24 hours, and her vagina.
....So now we get to the part where Jeff the penis is confused. Because, well, he's suddenly a penis. His body feels stiff and inverted, and his cloth prison feels like it was replaced with flesh. It was warmer in here, and the scent is different, too. And stronger. There's this strange musk to it.
And then came the strangest moment, as Jeff felt new muscles at his base push him out of his fleshy prison. Despite being exposed to the air outside, he still couldn't see or hear. He suddenly felt something rub his belly and chin. It happened too quick to identify, but it didn't feel quite like human hands. And the way he moved as he hung out of the prison, it felt like there was a rod of some sort inside of him. As he was pulled back into the prison, he realized what was going on. Not only was he a penis, but he was an animal's penis.
He was... an animal's penis. Something about that felt really taboo. Granted, it wasn't his decision to become an animal's penis. And, when you really think about it, is it really taboo for an animal's penis to be an animal's penis? It's not like he was fondling it or anything like that. It's just what he was, now.
The question remained, though: why? Why did his human self change into an animal, and back to male, at that? His host knows that he wanted to be a vagina. In fact, he'd still kinda prefer that. Did his host not like being female? Yeah, probably that. Oh well. At least this would still be interesting. Especially as he now felt himself sway inside his sheath, as his four-legged host roamed the house. That's what he was inside now, right? A sheath? No more underwear for him. Instead, the remainder of his 24 hours would be spent living inside the innards of a mystery animal's crotch.
At least it's comfy in here.
