Symbiotic Experiment for SeththeTolf by Draconicon

The tiger-wolf groaned as he slowly opened his eyes. His vision was so blurry that it took him a few seconds to recognize the long, familiar ears of his teacher, Mr. Hudson, but even then Seth didn't understand what had happened. His head felt fuzzy, and his arms - and his legs, too - felt heavy.

As the tolf let out a slightly louder groan, his teacher turned around to face him. To his surprise, Mr. Hudson was wearing the chemical-protection goggles that he usually reserved for big chemical experiments, as well as long, black gloves that ran up the rabbit's arms all the way to his elbows.

"M-Mr. Hudson?"

Even speaking felt like he was gargling gravel, but at least he could. He was half expecting to be unable to do that, with how hard it was to move.

The rabbit didn't answer him, though, and Seth pushed himself from side to side. Or at least, tried to. He gradually figured out that the heaviness on his limbs was due to the fact he was tied down, restrained by thick leather belts that ran across his ankles, wrists, and stomach. Even with his squirmiest moves, the high school senior couldn't break through the bindings, or slither out from beneath them.

"Mr. Hudson, what are you doing? Why am -"

"Quiet. The experiment is almost ready to start."

"Experiment? What -"

"I said quiet!"

The tolf shut his mouth, silencing a scared whimper in the process. He looked down and blushed as he realized that his body was naked, revealing everything to the professor, including his cunt-boy nature.

Yet the rabbit didn't seem that concerned about that. Instead, all of his attention was on the vial that he carried, and inevitably Seth was driven to stare at it too. The black goo inside roiled and swirled about despite the teacher's stillness, and he wondered if it was alive. That seemed almost impossible, but then again, so had being kidnapped and tied down by one of the teachers at the school.

His teacher stepped forward, swirling the glass around this time, and the creature inside went still. It was definitely a creature; this close, Seth could see tiny white dots that could be nothing but eyes. Mr. Hudson smiled.

"It's been a while since I could actually experiment properly with these things. I've had to keep them fed very carefully while they've lacked their hosts, you see, and it gets very exhausting.

"You see, these little creatures -" Mr. Hudson paused, shaking the vial again. "These little creatures are very eager to have new hosts. They work well with people, making them stronger, making them faster; it's all quite beneficial. However, they do need a bit of something in return. Can you guess what that is?"

Seth shook his head, not daring to answer. He couldn't think of anything that didn't sound super stupid, anyway.

"They feed on fluids, you stupid boy. Fluids. They are mostly liquid, after all, and they need to replenish their stock constantly. Of course, in previous subjects it has led to hospitalization through dehydration -"

Is he nuts?!

"- but I believe that I have them adjusted correctly now. After all, they are living creatures, the same as us. Forced evolutionary traits will make them seek other...sustenance, though still of the fluid variety."

"And...you plan to -"

"Yes, dear 'boy,' I plan to infect you with this, and see how it proceeds. After all, one cannot move science forward without practical application. Theory only goes so far."

"But -"

"Ah. I told you to be quiet. Now keep your mouth shut; you will have this in you, one way or another."

Seth opened his mouth again, but this time the rabbit shoved a gag down his throat. It was a long one, too, probably some sort of beaker twisted around to be used for something else. He gagged around the long glass tube as the teacher slowly uncorked the vial and tilted it, pouring it down right over the tolf's crotch.

He gasped as the cold creature pressed against his fur, right above his pussy. It was like feeling ice crawl over him, soaking over his fur and matting it down before leaving it completely smooth. As shudders ran down his spine, the tolf watched it spread further and further, leaving a hole around his crotch for the moment as the black smoothness ran down his body, over his belly and along his legs. Everywhere it touched, his fur turned black and smooth, and he swore that he felt it slithering into his skin as well.

Mr. Hudson already had a clipboard out, and was writing and reciting things as the black continued to cover him.

"It seems that the creature is leaving the sexual organs for later, but the integration between flesh and symbiote is astonishingly quick. Fur is buried beneath the growing body of the creature, and readings show that the pores are being filled with the creature, so that the binding is as complete and close as possible."

His pores? That seemed impossible, but it was the only idea he could think of that matched the feeling of the black stuff rooting its way into his body. As it went further and further down his legs, he could feel it tingling against his muscles, and he groaned, not wanting to watch as it got further and further along.

The feeling of it flowing over his bare feet, though, left him blushing. Tickling as it slipped between his toes, it left him gasping, even moaning slightly as it sank into his soles. He had to look down, and he saw his toes wiggling without his consent, the symbiote starting to take control of his body and move it around.

Of course, that wasn't the only change. Where the black covered his legs, and his stomach, muscle had replaced the blandness that had been there before. His abs had become a six-pack, looking almost like those of a cartoon hero. The tolf's untreated upper body still looked like that of a weedy high school student, but from the chest down...well, he looked like something out of a comic book.

Still, it didn't help when his legs suddenly kicked on their own volition, ripping through the bindings that kept him down. Seth yelped as he was rolled off of the table, the legs powerful enough to pull him free of the other bindings that were holding him to the table. Mr. Hudson rapidly backed away, but the creature seemed more interested in taking control of the tolf than it was in the teacher that had released it.

He soon lost the use of his arms, leaving him helpless to do anything but stand there. The goo around his crotch slowly folded inwards, and Seth would have collapsed if his body had still been his own. The goo pulled at his pussy, spreading it wide open as more and more of the goo slid inside of him, the creature filling him up and taking control of everything. It happened behind him, too, sliding into his ass, but it was far harder to feel over the strange intrusion in his sex.

It forced him wide open, more than any of his toys or his fingers had ever done. It was like being fucked, in a way, but without any of the pain he had imagined would come with it. The usual moisture of his pussy didn't come, though; he imagined that the creature was sucking it up, feeding on it, just as the professor had said.

The creature kept sliding along his body, encasing his arms fully before reaching up to his head. The tolf bit his lip, not sure what would happen, but feeling that he was about to lose himself entirely.

He was right, as the encasing creature slid over his head and into his ears. It was like feeling some warm, thick blanket wrap around him, bringing him to utter stillness. He could see, he could think, but there was no way he could move from where he was. He'd become a passenger in his own head as the symbiote slid over him.

The same muscle growth that had occurred below continued on his upper body. He shuddered beneath the creature, panting as his arms thickened, his chest expanded with muscle. There was something powerful, wonderful in the way that he was being molded; as much as it terrified him to lose control, he was enjoying the feeling of his body being made into something else, something better, stronger, and faster than it could have ever been, normally.

It wasn't just his muscles being changed, though. His sex, invaded by the symbiote, was spread out wide. When the creature looked down - making him do the same - he could see that he was forced into a display that would have made some porn models blush. His sex was covered up by the creature's body, but it looked like someone that was at the height of their arousal, simulated 'pussy juice' lines running down from his spread open sex. He panted softly, though his mouth remained closed, as his hand was brought down to his sex.

Mr. Hudson watched with that creepy stare of his as Seth slid a finger into himself, the rabbit still writing and talking to himself.

"Symbiote is taking conscious effort to feed itself. It seems to have located the primary pleasure centers -"

"Ahhhh!"

"And has not yet silenced the vocal cords of the subject. But pleasure centers seem to have been found, and are being stimulated."

Stimulated was a mild word for it. Somehow, the creature knew exactly where to touch, exactly what to stroke and finger and rub to get the maximum results. If he had been alone, Seth swore that he would have drenched the bed and the mattress both already from how wet he was, but the creature was devouring it all. He shuddered as it kept pushing his buttons, forcing him into his first, and rapidly after, his second orgasm in the suit. His toes curled hard enough that they actually punched through the floor with his new strength, momentarily rooting him to the place.

"Note to self. Ensure that the body is significantly restrained when extraction process is to -"

" Extraction is impossible."

The voice had come from Seth's mouth, but it wasn't him speaking. It must have been -

" This creature is ours. He will not be parted from us."

The rabbit blinked, looking up from his clipboard at the statement from the symbiote itself. Seth was just as shocked; he hadn't thought it through enough, but he didn't expect to be claimed so quickly. The teacher cleared his throat.

"Well...this complicates things a bit."

The End
