No longer distracted by the need to pee, and now in the dark and quiet confines of Nathan's sheath, Jake was left with nothing but his thoughts.
Today was weird, to say the least. Start of the long weekend from school, intending to spend a normal evening goofing with Nathan, but turned into his penis, instead. And not just any penis, but a penis that looked like a sphynx cat, inside the sheath of his friend who got turned into a German shepherd furry.
Jake was still annoyed that Nathan had turned him into something so degrading, especially to the point of using him to take a piss. But he wasn't as mad as he was at first. Thinking about the evening that just went by, it wasn't all that bad. Parts of it actually almost seemed normal. Still weird, of course. No longer having legs; being permanently affixed somewhere in a dog's sheath; no longer having hair, while at the same time being a cat; the world so much bigger than he is now, with furry legs towering around him and a furry ballsack hanging below; and of course, the fact that his mouth was effectively a urethra.
Jake rubbed his muzzle at this thought. It was so strange, having a cat's mouth instead of a human one. Sticking out with his nose as a single object protruding from his face. He opened his mouth, feeling the feline teeth within. He stuck his tongue out, longer than a human's and licked his nose. As a result, he also accidentally got a taste of the sheath's lining. The flavor wasn't bad, but certainly odd. He reached a hand up and felt the lining. Very fleshy, and definitely warm. If he were still a person, he'd never dare stick a finger inside a dog's sheath, nor would he put his hand even near a dog's penis. But right now, he IS a dog's penis. Still a person, in a way, but a penis. Wrapped snug within a dog's sheath. He reached down his body. His skin felt somewhat normal, but still strange. His body quickly tapered into the shaft of a penis. At his base, the skin doubled back to wrap around him. He noticed that somewhere along the way, he lost feeling. He had an edge of some sort, even if it wasn't a physical one. He was a part of the sheath, but the sheath was not a part of him.
Jake reached back up to his head, feeling it again. The skin of his head had a different feeling, not unlike the head of a penis. Thankfully, rubbing his own head didn't seem to cause any arousal. He also noticed that he didn't seem to be scratching them. He felt his hands together, and realized that not only did he no longer have any fingernails, but he didn't even have claws. He supposed it made sense; wouldn't want to scratch up the lining of his (temporary) home. Reaching back up to his head, he felt his feline ears. He tested their muscles, turning them and folding them back. He played with them a bit, and they twitched as a reflex. Having ears not only more sensitive to hearing, but more flexible, was actually kinda neat. He kinda wished that Nathan had turned him into a sphynx cat like he turned Nathan into a German shephered, without the "being a penis" part. Having a tail would likely be just as interesting as having these ears.
Jake sighed at the thought. And then he realized, until that moment, he hadn't been breathing. He held his breath again, and waited. And waited some more. But at no point did he feel the urge to breath. It seemed that as a penis, he didn't need to breath, only really having lungs to speak with his squeaky voice. Jake wasn't so fond of that part. It was jarring to hear that voice coming out of his own mouth. He doubted that either he or Nathan could bare to hear that voice over an extended period of time. Admittedly, though, he was a bit curious how it'd sound if he tried meowing. But Nathan would probably hear him, and poke fun of him for getting into his transformation. In fact, Jake realized that Nathan probably felt everything he was doing. Deciding not to risk drawing any furthur attention to himself, he made himself comfortable and tried going back to sleep.
