It was toward the end of the bad movie that Jake started to feel weird. Granted, he already felt weird, being turned into a penis-cat hybrid, but there was this strange feeling eminating from deep within him. Not really sure what it was, he initially ignored it, distracting himself with the movie's end. As the credits rolled though, that feeling seemed to grab his attention more. Knowing that his host must be feeling the same thing, he called up to Nathan. "Hey, I feel weird. I mean, extra weird. Do you feel what I mean?"
Nathan hesitated to answer. "Uh... yeah."
"I'm starting to feel a little tingly. I know I've never experienced before, but, it also feels familiar. Kinda reminds me of..." Jake went wide-eyed as he realized what the feeling was. Of course it felt familiar -- it's the feeling of needing to pee, only amplified through his body, because he was the penis! "Oh, no."
Nathan smirked, having been looking forward to this part. "Sorry, Jake. It's a natural bodily function." Nathan got up off the sofa and began walking to Jake's bathroom.
"Wait, wait!" Jake pulled at Nathan's furry balls, again.
"Ah! Hey, careful! I might accidentally pee a little if you do that! You don't want me peeing on your floor, right?"
"Can you hold it in?"
"Not if you keep doing that!"
"I mean in general!"
"Huh? Well, yeah, I guess, for a bit, but not too long. Sorry, but there's no way I'm gonna be able to hold it all night. You're gonna need to get peed out of."
"Not if you go to bed."
Nathan tilted his head, in a dog way. "What?"
"Yeah! Let's go to bed, so your need to pee will relax a bit, and by the time you wake up, the Chronivac will be able to change me back to normal, and I can get out of this situation!"
"I'm not sure that's how that works. Besides, it's the long weekend! We don't need to go to bed this early!"
"Look, I get that you wanted to play a prank on me. Well, ha, ha, you got me. But making me vomit up your piss is taking it too far. Come on, please? We're friends, right?"
Nathan intended to let out a groan, but it sounded more like a dog's whine. Peeing was probably the most interesting part of a cock transformation. He so wanted his friend to experience that. But, he didn't want to strain their friendship too much. Maybe tomorrow, they could swap roles, and he could be the one to get peed out of, instead. (Honestly, he'd do that right now, if he hadn't tricked Jake into thinking there was a time limit.) Still a bummer they can't stay up later, though. Nathan sighed. "Alright, alright. Yes, we're friends, I'm sorry. Let's go ahead and head to bed."
Nathan started heading into Jake's bedroom, when Jake stopped him again. "Hey, wait, not my bed. I don't want your naked dog butt sleeping under my sheets. You brought your sleeping bag, right?"
"Well, yeah, but, you're not using it. Don't you want to sleep in your bed, too?"
"Look, if I have to sleep in a sleeping bag..." Jake pokes Nathan's sheath, "then you have to sleep in one, too."
Nathan chuckled a bit. Nice to know that Jake can still make a joke about his situation. For that reason alone, Nathan turned back for his sleeping bag.
