“Y10 Ali-yens: Rubber Egg” by bya

Levi yawned. The young rex rested his chin on his hand propped up by his elbow. His recess period was nearly over and he'd spent all of it thus far lazing on one of the picnic tables, he felt as though goofing off on the swings or the jungle gym wasn't “cool” anymore and he was a little too old for that now. Too old for the playground, but not so much that his feet touched the ground from sitting at the table; as Levi watched the other students run around his legs swung aimlessly back and forth as they hung off the side of the wooden bench. By all metrics, he was an average boy. Liked monsters and video games, read the occasional comic, stayed up too late even on the nights his parents warned him not too; the usual fare.

His skin was a moderate shade of blue violet and he had crystal-like cerulean eyes. Parts of Levi's body, like the sides of his head and his shoulders and upper legs, had little areas of dark purple patches. The young dino was dressed in the very commonplace outfit of a cartoon T-shirt and a pair of loose cargo shorts.

Across the park one of the instructors supervising everyone took a whistle out from her pocket and blew it twice signaling that recess was ending and that all the students should start making their way back toward the building. Levi sighed and swung his legs forward slightly as he hopped off of the bench and began slowly meandering his way back toward the school. He walked past a couple of swing sets, but as he got to the end of the last one he spotted something in the dirt that caught his attention. As he knelt down to look at it Levi saw it was a small black rubber ball. The rex picked it up and looked it over. He'd seen ones like it before at the grocery store inside the coin-operated vending machines, specifically the one on the far opposite side of the machine that dispensed the similar looking gumballs as to not confuse the two. Strangely though unlike the gum, which were an assortment of colors, all of the rubber balls were black.

As Levi resumed walking he wound his arm back slightly and pitched the ball at one of the slides as he passed by. The ball hit the angled metal surface with a soft thump and bounced right back in Levi's direction. The boy stuck his hand in the air to catch it as it passed overhead, grabbed it, and put the ball in his front pocket as he returned to the campus.

Levi sat through his history class bored out of his mind before moving across the hall to mathematics where a test awaited. About 80 or so minutes had passed since recess; the black rubber ball made a slight bump in the rex's shorts that was vaguely uncomfortable only when the boy was aware of it. The teacher passed out tests to each of the students and Levi got to work as soon as one of the papers was placed in front of him. He wasn't a star student, but he was gifted enough in the subject to be able to usually breeze through the first half or so of the test before he started hitting the problems that took a little longer for him to solve. This test was no different; as Levi stared at the numbers on the page he alternated between chewing on the end of his pencil and jotting down the next step in the equations as he did the math in his head and in the margins of the paper.

Throughout this, the bouncy ball that the rex had stuck in his pocket remained where it was. However, the process of having been handled, jostled around, and now pressed up against the warmth of the boy's thigh was starting to have an effect on the object. Gradually, the little knot the toy made in the front of Levi's shorts had started to vanish. Inside Levi's pocket the shape of the ball deformed as it very slowly flattened down, now assuming the shape of something more akin to a ball of clay that had been squished slightly. As the rubber ball continued to deform it began to weaken until a split opened on its side. In a fraction of a second the split reached down the entire side of the flattened ball and from it a thick black goo poured out into the rex's pocket.

Now free from its egg, the black slime collected itself inside of the cloth pouch leaving behind an empty and crumpled black rubber shell. The goo slowly explored its surroundings, able to feel the warmth from Levi's leg but unsure as to where it currently was. It seemed to the slime that everywhere it tried to go it eventually hit a wall in the form of the seams at the edges of the boy's pocket, but as it followed one of the seams all the way down to its bottom corner it discovered a hole in the material large enough for it to start pushing itself through but still small enough for the ball it was formerly contained in to have not fallen out of.

As the black slime pulled the last of its mass through the hole in Levi's pocket it found itself still sitting atop another kind of fabric, the boy's underwear. Now that it had crossed one of the layers of cloth however the slime was able to pick up the very faint scent of the rex's fledgling musk. Slowly, the goo began to creep upward toward the source of the scent until it was sitting right on top of Levi's very slight bulge. The goo sensed it had to be close to its target, but there was still something impeding it from where it wanted to go. The black slime spread itself out in all directions as it began searching for a way around this barrier too until it eventually hit the cross-seam just off to the side of the front of the boy's garment. Realizing it could now potentially go down yet another layer, the slime nudged itself under the gap in the fabric and began pulling the rest of its mass further inside.

While this was going on Levi was mostly none the wiser. Lost in his focus on the test, he thought he might've felt something move on his leg but the feeling didn't register strongly enough for him to really notice. The rex did feel something shift across his crotch causing him to shift slightly in his seat, but again he didn't think much of it. What did get his attention though was when he felt a very strange warmth suddenly envelop his sheath and tender sack. Levi's pencil dropped from his hand as he quickly looked down at the front of his shorts. Before he could form a second thought he felt whatever it was that was down there gently squeeze his genitals and dip into the slit of his sheath. The rex winced and exhaled sharply, his hand instantly shooting up into the air.

“Yes, Levi?” The teacher asked from his desk.

“M-may I go to the bathroom please?” Levi stammered out.

The teacher sighed. “Levi, you know the rules on leaving to use the restroom during a test.”

Levi shuddered in his seat, the boy pulling his arm back down as he felt the strange warmth on his crotch squeeze him again and flood into his shallow sheath. He quickly stood from his desk and made a dash for the door.

“Levi, what are you-” the teacher started.

“Sorry!” The rex said, cutting him off. “It's an emergency!”

Levi stormed out of the classroom letting the door loudly close behind him as it rebounded off of the doorstop on the wall after having been flung open. The boy hurried down the hall to the nearest restroom and as he grabbed the handle of the door to pull it open he froze for a moment, trembling again and moaning softly as he felt the warmth push further in and completely wrap around his soft member. The rex yanked on the door handle and stormed into the bathroom, knocking into the door of the first stall with his shoulder and quickly closing it behind him and sliding its lock over to the side.

The boy's hands quickly made their way to his shorts where he tugged at its fasteners to undo them, stopping yet again when he felt another intense contraction around his length. Levi shivered once more, the rex gritting his teeth and sighing through them as he steadied himself and resumed unbuttoning his shorts. He hastily tugged them down with his underwear revealing the light purple skin of his sheath and sack. A familiar sight, however as Levi clenched his pelvic muscles to push his shaft out of its sheath what emerged wasn't what the boy was expecting.

Levi gasped worriedly as he looked down at his crotch. As the slit of his sheath parted open and his member pushed out rather than seeing the usual fleshy pink, his organ was instead a dark matte black. Without thinking, the boy quickly reached down to touch it but flinched and recoiled immediately as soon as his fingers met his shaft. It didn't hurt, but the sensory feedback from touching his boyhood was too much for Levi to process as its sensitivity had spiked far past what the rex was used to.

A moment after withdrawing his hand the rex cautiously reached back down to touch his shaft again, this time doing so very softly. The boy sighed gently, a light moan escaping his lips as his fingers gingerly wrapped around his length to see what was happening to him. The flesh of his boyhood felt dense, firm but with a little bit of give to it. It had become incredibly sensitive to touch, too. Its texture was also strange, smooth and taut. The closest comparison the boy could make was that it felt almost like... rubber?

He didn't realize it, but that's exactly what he was feeling. The black goo that had emerged from the small egg Levi had unknowingly pocketed was a sort of symbiotic lifeform. As the slime enveloped and encased his flesh it immediately began bonding to it, seeping into his cells and changing them at their most basic level. Levi's boyhood had already undergone significant changes in just the few minutes it had been since he'd darted out of the classroom. Its squishy pink flesh was rapidly being replaced with a form of pseudo-organic rubber, a process that was quickly nearing its completion.

Levi trembled as his fingers traced his length and experimentally squeezed it. In the past he'd explored himself several times and was no stranger to how enjoyable it felt to touch his boyhood, especially when it was firm like this, but he didn't really understand why that was. What the rex really didn't understand was why doing that felt even better now, let alone why his private part was jet black and slippery. The changes were frightening, but the boy's fears were mostly assuaged by just how good everything felt. His shaft tingled everywhere his fingers traced, both as an effect of the nerves becoming hyper-sensitive and the last vestiges of his normal skin being consumed by the living rubber.

As the boy stood in the stall curiously stroking his small shaft he noticed a thick bead of clear fluid slowly push its way from its tip, drooling down the head of his shaft and onto his fingers. Levi brought his hand up close to look at his fingers, rubbing them together and discovering whatever this substance was was incredibly slippery. As he rubbed his thumb and forefinger together he wondered what this slickness would feel like on his shaft, so he quickly lowered his hand back down to his boyhood and began smearing the slippery fluid onto his black flesh. The rex moaned softly, he hadn't even resumed stroking his length yet and just the sensation of rubbing the slick pre on his shaft was already sending tingles of pleasure up and down his body. He gently wrapped his fingers around his boyhood again, cooing lightly as he began making little passes along his length.

By now the black goo had fully converted the boy's flesh into its new form. It retained its same overall shape, but where there was once virgin dinosaur skin was now uniformly black latex. Though his boyhood had been fully consumed, the organism was not content to simply stop there. Beyond the base of Levi's shaft, which he couldn't see given that his sheath was in the way, the rubber continued to intrude further into his body. Thin tendrils of black slime slowly wormed their way up into the rex's abdomen and spread their influence ever deeper. More immediately however the tendrils also doubled back from the boy's shaft and reached his testicles. The slime had made it into the ovoid organs, breaching each of them with a thin rubbery needle of its mass that quickly branched off into several thinner heads that merged with the rex's balls and began to corrupt and twist their genetic makeup as well.

Levi was aware of none of this, he was simply relishing in the heightened pleasure of fondling and stroking his boyhood. His member felt practically electric, buzzing with a building urgency that the boy had never experienced before. The sensation intrigued the rex and he began to focus on it, stroking his small length more purposefully. Past a certain point Levi knew some kind of peak was coming, he was building up to something by doing this and whatever that peak was he wanted to feel it. There was no turning back. The pace of his stroking quickened and, suddenly, his knees buckled slightly.

Levi gasped and let out a moan as he reached his first orgasm. As the boy hit his limit he let go of his shaft, the sudden jolt of pleasure startling him. He cried out as he felt his shaft throb on its own and looked down in time to see a thick glob of clear fluid spurt from its tip. Another one followed with a slightly weaker pulse and the resulting strand of liquid splattered onto the tile floor. A third generous emission followed before his release quickly tapered off and the last couple slowly oozed out from his length.

The rex took a few moments to catch his breath and come down from the intense rush he'd just felt. He sighed several times, savoring the curious warm bliss that washed over him as his climax wound down. Levi looked back down in front of him at the small mess he'd made on the floor and seat of the toilet. He ran his finger through the clear fluid on the seat and experimentally rubbed it between his fingertips again. He'd never felt something slick like this before, especially something that had come out of his body. His only point of reference was pee, and whatever it was that he was swirling around in his fingers definitely was not that. His body was making something else, this weird... clear stuff. Perhaps it had something to do with the sudden change to his boyhood.

Levi looked back down at his shaft to see that its flesh had adopted a slight shininess to it as opposed to the dull black it was when he'd first tugged his clothes down. Part of that was due to the rex coating his shaft in the pre he was now producing, though part of it was also because the rubber replacing his skin had fully completed its transformation and it would now always have this sheen to it. The rex took hold of his boyhood again and slowly stroked it a couple more times, the rubbery skin still sending out little flickers of pleasure, until a sudden realization hit the boy.

The test. He'd just stormed out of class and left everything at his desk! How long had he been in the bathroom? Was there even enough time to finish the problems he hadn't done yet?

Levi let out a frustrated sigh. He sucked his abdomen in a bit and flexed his pelvic muscles slightly differently to pull his shaft back into its sheath. The boy shivered slightly as his boyhood disappeared back inside of him, even the feeling of his new rubbery flesh sliding against his slit felt good now. He figured he would have more time to look himself over when he got home, for now he had an assignment to finish. Or, however much he'd still be able to do with the time left in the class period. He pulled his pants back up, washed his hands, and made his way back to the classroom.

As he opened the door to the mathematics room and stepped back in his eyes locked with the teacher's who was visibly annoyed.

“Uh... sorry,” Levi said with a gentle shrug.

The instructor didn't respond, he just focused his attention back down to the papers on his desk.

The last couple of hours of the school day ran their course and Levi found himself headed toward the bike racks at the front of the campus to grab his and start his trip home. As he approached the rack with his bike he reached into his pocket to retrieve the key to its lock, though as he wriggled his fingers around something else caught his attention. It felt like an empty candy wrapper but as the rex pulled it out of his pocket to look at it he realized it was something else, a black crumpled mass that felt slightly rubbery. It resembled a small egg in a way, just with a very thin and flexible outer “shell”. Given the strange events of the day the boy had completely forgotten about the rubber ball he'd picked up at recess. He was about to pitch what he thought was trash onto the ground but stopped just short of it when it finally clicked that what he was holding was black... and felt rubbery. Just like what had happened in the bathroom stall.

Levi brought the empty shell back up to his face to look at it closely. He squished it between his fingers and pulled on it slightly but stopped when he noticed it ripped very easily. It felt dry, and smelled like a wad of rubber bands. The rex remembered picking up the ball at recess and putting it into his pocket. This pocket. The ball was gone, and in its place was whatever this was, an empty shell about the same size as the ball and the same color and texture. As Levi looked at the squishy shell he knew it had to be the ball, but couldn't explain how it went from a functional little toy to this empty rubber husk. Obviously, there had to be something inside of it if this is all that was left. As the boy slowly put the pieces together he felt a knot well in his stomach. Whatever came out of this ball, is that what caused his private part to change?

The rex shivered slightly where he stood as a feeling of slight unease hit him. He stuffed the rubber shell back into his pocket and fished around for the key again, retrieving it and unlocking his bike from the rack.

As Levi reached his home he dismounted his bicycle and walked it around to the back of the house. He retrieved the same key from before and flipped the ring holding it around to its other key, the one to the house. He stepped inside, his eyes catching the clock in the den as he entered. It was a little after 3:00. His parents usually arrived home from work a couple of hours from now. The rex hurried into his room dropping his backpack just inside the door as he entered. He had a worksheet from his science class to finish, but working on that was the last thing on the boy's mind.

The young dinosaur hopped onto the side of his bed, unfastening his cargo shorts as he settled atop the mattress and bedding. He pulled his bottoms down far enough to expose his sensitive parts and immediately his right hand found its way to his sheath and sack to gently cup and fondle them both. He cooed lightly, his exploratory touch feeling as nice as it always had since the rex had recently discovered this curious sense of pleasure several months prior. His balls filled their pouch out nicely, perhaps even a little more nicer than before. It was nearly imperceptible to the boy but his sack felt just a little bit tighter as its contents had swelled in size a very small amount since earlier that afternoon. Each of his orbs were still in the early stages of being converted into new organs and were now a little larger to make room for the tendrils of black slime that had forced their way inside and thickened considerably to the point that each of them were barely noticeable on either side. Of course, Levi wasn't aware of this, he just enjoyed how nice it felt to caress and grope his soft light purple skin.

Levi sucked in a light breath and clenched his pelvic muscles. With a soft flex he watched as his erect boyhood slowly emerged from its sheath. It was still the same dark black as before, and just as shiny too. As the organ twitched a couple of times on its own the rex noticed that it was a little larger than before. It was only a small amount, perhaps half an inch, but given that he wasn't very large to begin with the difference was immediately visible.

The rex's hand slid upward from fondling his sack to holding his member. It still felt quite rubbery, and was also very slightly slick. Feeling this slickness caused Levi to instinctively start stroking his length again, the young rex moaning softly as his boyhood instantly lit up with sexual pleasure. He let go after a few moments and sifted through the front pocket of his shorts to pull the rubbery shell out of it. He inspected it again before looking back down at his boyhood. Something didn't quite add up, but whatever it was the resulting effect was enjoyable to Levi in a way he hadn't known before. He tossed the crumpled shell aside and resumed teasing his length, rubbing the budding bead of pre forming at its tip across his rubbery flesh while his toes curled back slightly in response.

Levi remembered the rush he'd felt earlier and could feel another one gradually building up inside of him. He smiled to himself as that newfound sense of urgency began to manifest. The rex didn't know why what he was doing felt so good, but he was eager to get there again. He shifted on the bed slightly, spreading his legs a little further apart to get more comfortable. The boy continued to stroke his shaft, his pace becoming more erratic as he neared his peak until a sudden moan punctuated its arrival.

Levi softly bit his lower lip as a wave of euphoria washed over him for the second time. He continued to softly stroke his boyhood through his climax feeling as his length flexed and throbbed, the rubber skin practically stretching out with each contraction, as another generous glob of thick clear fluid rushed up and out of its tip. His gaze met his crotch to watch as another jet of liquid erupted from his boyhood and landed on his bed sheets. The rex closed his eyes and moaned again focusing on the sensation of the thick fluid lancing from his member. There was even more of it this time, though like before Levi's peak soon tapered off and as the boy came down from his high he realized he had something of a small mess on his bed to clean up.

He let go of his shaft and softly cupped and caressed his balls again feeling their post-orgasm tightness and rumbling to himself. The young dinosaur curiously fondled his shaft again. It was very slightly softer but still mostly erect, a state that it was now staying in as far as he could tell. Despite the sudden and confusing changes Levi welcomed them, though part of him knew he should probably keep this to himself given what little he knew about this part of his body. It was called “private” for a reason. The boy grunted slightly as he clenched his lower muscles again pulling his semi-erect shaft back into his body in the process.

The remainder of the day passed without incident. Levi's parents arrived home from work and collectively they made small talk about the day over dinner. The young rex carefully danced around the topic of his mathematics quiz by saying it was “harder than usual” because his teacher threw in some surprise problems. It was a way for Levi to temper his parents' expectations if it came to be that he'd missed several of them when he had to hurry up and scribble out the remaining answers due to the “other events” of the day that he was keeping to himself eating up a chunk of his class time. After dinner Levi spent his evening reading comics in his bedroom before changing into his sleepwear and getting into bed, the boy naturally taking a few moments to privately admire his changing boyhood in the process.

Levi slept soundly through the night though while his mind was able to rest easily, elsewhere the boy's body was continuing to work overtime. The two tendrils of black rubber probing into the rex's balls grew larger as the mass of slime continued to slowly spread into his body from its initial entry point. His ovoids swelled in size as the black goo inside gradually filled them up, changing them cell by cell, until each of the organs had been fully consumed and converted. Levi's sack plumped up considerably, his soft purple skin tightly gripping two new organs made entirely of pseudo-organic latex. With their transformation complete his orbs now produced a synthetic version of his body's original hormones, slightly altered to weaken his immune system in order to allow the rest of the rubber slime to invade the young rex's body completely. Of course, the organs the rubber goo had just finished consuming were also originally meant for reproductive purposes. They would continue to serve this purpose too, although now in their fully corrupted state they would be supporting a different kind of new life.

The faint sound of a wristwatch beeping woke Levi. The rex groaned slightly, the boy's annoyed waking sounds turning into a yawn after a few moments. He reached over to his bedside table and fumbled with the watch to turn it off. Levi laid in bed for a couple of minutes as he slowly shook off the drowsiness of waking up before kicking off his blanket and sitting up on the edge of his mattress. He yawned again stretching his arms above his head a little bit but stopping when he noticed something different about his body, a strange weight at his crotch. 

Levi looked down at his underwear and noticed that the bump his genitals made in the fabric was much larger than it normally was, even compared to the night prior. He gently palmed the bulge in his clothes and could feel even through the layer of fabric their increased size. The rex tugged at the elastic of the garment and peeked under them curiously, greeted by the sight of his sheath and swollen sack. He let go of his underwear and hopped off of his bed in order to start getting dressed for the school day ahead.

As he took off his loose sleep shirt and underwear Levi gasped gently as the weight of his sack properly made itself known now that it wasn't being tightly held up by something. The boy looked back down at his crotch again and cupped his balls in his hand. They were each easily more than twice as big as they were before he'd fallen asleep, but they also felt much heavier and fuller than even their new size would imply. Levi stepped over to his closet and opened it to look at himself in the vertical mirror hanging on the inner side of the door. His enlarged sack was quite noticeable, each of his balls filling his pouch out so much that their individual shapes were visible now. The young rex eagerly reached back down to fondle himself and feel their heft again.

He took turns caressing each of his orbs, rolling them as best as he could in his hand. It was strange to the rex just how dense they felt. He gave his sack a very gentle squeeze and trembled slightly. They were sensitive, but in a way that somehow differed from how uncomfortable it used to feel. It didn't hurt, but the soft squeeze did feel strange and foreign. The sensation was somewhere between a tingling numbness and the dull pain of a stomach ache. As Levi looked himself over and explored his swollen orbs he noticed the raised bump on either side of them, the one that the tendril of black goo had formed earlier. In the early stages of the boy's infection the bump was hidden in the loose skin of his sack but now that his organs had grown larger the tendril had grown with it and was now about as thick as a pencil. The way it looked reminded Levi of the veins on his wrist and as the rex gently pressed his finger against it he could feel the strange bump slowly throb.

Strangely, the throbbing did not match his heartbeat. Levi wasn't aware of it, but the “veins” on each of his balls belonged to the invading rubber, not him. Initially they served the purpose of giving the organism a direct line to the boy's reproductive organs to start the first stage of his host cycle. With that process complete, the veins grew in size to help facilitate the stage to follow. The pulse Levi felt wasn't his veins pumping blood to his swollen balls, it was the lifeform pumping the latex goop his balls were now making elsewhere into his body in order to spread further.

While Levi explored his growing anatomy he could also feel his boyhood within his sheath. He was too distracted by the size of his balls to notice that his shaft was uncomfortably tucked away inside of him. The rex clenched his muscles and jutted his hips forward just a bit, his eyes widening as he saw in the mirror what emerged.

“Wh... wha...?” The rex mumbled aloud as he glanced down at his crotch after seeing himself in the mirror.

Levi's shaft was still jet black and rubbery with a noticeable sheen to it, the way it was before he'd gone to bed, but it too had grown in size overnight. The boy had no frame of reference to gauge what he was looking at. He'd never seen anyone else's member before, only his, but the best comparison Levi could make was his was almost the same size as the candy bars he favored from the grocery store.

Cautiously, the boy reached down to hold his shaft. It felt warmer than usual, smooth and slightly slick as well to match its new rubbery texture. Overall it was the same shape it had always been, a normal shaft that ended with a lightly defined head and pointed tip, but it was just... bigger now. As Levi held his boyhood he felt how prominent its once small veins were in his hand. He squeezed his shaft gently and felt the organ pulsing and throbbing softly, once again not to his own heartbeat but to the unflinching pace the rubber organism was using to spread its influence. Experimentally, Levi ran his grip along his shaft, trembling as his entire organ lit up with strange pleasure.

“A-ah...” the young rex muttered as he gently bit his bottom lip.

“Levi!” His mother called from around the corner leading to his bedroom. “Are you ready? Breakfast is waiting!”

“C-coming mom! Just a sec!” Levi said, immediately snapping out of his trance and shuffling through his closet to get something to wear.

Levi hastily got dressed, bolted into the kitchen to eat, and rode to school.

The day was as uneventful as the average day of school usually was, but time seemed to pass a little more slowly as Levi found himself restlessly wanting each period to hurry up and end faster. His mind was racing with thoughts about what he'd seen and briefly felt that morning and he wanted the privacy to explore those changes somewhere other than one of the bathroom stalls. As the clock neared the middle of the school day and Levi waited around in line for recess, he finally snapped and decided he couldn't wait any longer. With just a few minutes left in the period he approached the desk of his history teacher.

“Did you need something, Levi?” The teacher said quietly, not looking up from the paperwork in front of him.

“Yeah...” Levi started. “Is it okay if when everyone else goes to recess in a few minutes if I go to the uh, study hall instead?”

“Huh?” The much older dinosaur said as he turned to face the rex. “Do you have homework to do or something?”

“Uh, well I don't think I did so good on the math test yesterday,” Levi replied as he started making up a lie on the spot. “I think I should practice the lesson again in case, uh, I can redo the ones I missed and get a better grade?”

The teacher thought for a moment.

“Sure, that's fine I suppose,” he replied. “Just be mindful of the clock so you don't miss lunch.”

Levi nodded and sat back down to begin packing his things into his backpack. As the class dismissed the instructor guided the students out the door and watched as they walked down the hall toward the recess area. Levi briskly went in the opposite direction further into the school. As the history teacher glanced over in the rex's direction he did so just in time to see the boy turn and walk the wrong way from where the study hall was.

As soon as Levi rounded the corner and was out of sight the young boy picked up his pace of walking and hurried to the bathroom. Before pushing the door open he glanced to either side of the hall. No one was there. As he entered the bathroom he quickly ducked his head down and looked at the three stalls. No one there either. He made his way to the end of the restroom and entered the last stall closest to the far wall.

Levi took his backpack off and placed it on top of the toilet tank. He hastily unbuttoned his pants and pulled them down with his underwear, sighing to himself as he was finally able to get some time to himself. It wasn't ideal nor what the young rex had in mind but he couldn't wait any longer, it was driving him crazy. He cupped his swollen balls and held them gently, a smile creeping over his face as the familiar pleasant feeling washed over him. The rex grunted softly as he pushed his boyhood out of his sheath, his half-erect shaft drooping slightly for a few moments as it firmed up with every throb.

The rex looked down at his shaft, admiring its size. Levi didn't know why the sight of it made him feel so excited, he was in this same bathroom just a day prior and in that time his package had grown considerably. Perhaps the more it grew the better it would feel. The unnatural black color his member had changed to was still somewhat strange to the boy but because it didn't hurt, quite the opposite actually, it wasn't something he was fretting over anymore. He found himself liking the way his member looked now compared to when it was pink. He grinned as he eagerly moved his hand from his sack up to his shaft, a soft moan escaping his lips as his scaled fingers touched the black rubber.

Much like before Levi found his member to already be somewhat slick. As his fingers slid along his enlarged length Levi shuddered. Every inch of it felt incredible to touch. The rex paused after one slow stroke, feeling his boyhood pulse several times in response to the attention. Every time his rubberized shaft throbbed it felt taut, tight like the organ was practically stretching when it flexed. He felt something welling just past the base of his shaft and each time Levi's length flexed the mass moved a little further up. The rex could feel it through the bottom of his member, a formless “something” that shifted and moved as he gripped and held his length. As the mass reached the tip of his shaft Levi watched as a thick bead of clear fluid, larger than any of the previous ones he'd seen before, emerged from the slit of his boyhood and slowly oozed down its underside.

Levi let the thick stream of fluid reach his fingers and with the next stroke of his shaft he messily spread it across his length, the substance making his already slickened shaft even slipperier to hold. The liquid was as slick as it had always been but was now thicker in consistency, feeling more like a syrup than a liquid. Even though there was no one else in the bathroom the rex was trying to keep quiet just in case, but as he rubbed the clear pre along his shaft he practically involuntarily let out a soft moan. The rex continued to slowly stroke his member, already feeling another thick stream of pre building up and making its way through his shaft. As it emerged he greedily worked it all over his rubber flesh.

Not long thereafter Levi could feel the now-familiar urgency of release building inside of him. The young rex was slowly losing himself in a maze of pleasure, unable to focus on any of the individual things pulling his senses in every direction. He just wanted to feel the intense release he knew was coming. The dinosaur's breathing staggered, his legs trembling ever so slightly as he braced himself. His hand ran along his shaft a couple more times until another involuntary moan escaped the boy's mouth as he reached his peak.

Anticipating a mess, Levi pointed his boyhood in the direction of the open toilet and as his organ flexed the boy watched as a thick rope of pure black slime erupted from its tip and splashed into the water in front of him. The rex cried out in pleasure, his eyes widening as his shaft contracted again and he watched another jet of black goo shoot out of it. A third followed, Levi's orgasm remaining just as intense as it was when it started. The rush was almost too much for the young dinosaur to bear. He caught himself on the door of the stall and moaned again, his voice cracking into a slight whimper as more of the black substance lanced out of him and splattered across the tile floor. Finally, Levi felt his climax begin to wane. The powerful jets of slime lessened to a subdued trickle for the last several throbs of his shaft.

Levi remained braced against the door, practically out of breath. After several deep gasps he roused himself from the wall and surveyed the mess he'd made. The sight of the black slime startled him, though Levi quickly started piecing together that the goop was the same color that his boyhood had turned so if one thing had already changed color it shouldn't come as a surprise that the clear fluid he'd seen the first couple of times might also change as well. Whatever the new black substance was though, it was strange. It had gotten onto a couple of things in the stall but Levi was focused on the toilet in front of him. Where the slime had landed in the water it didn't disperse or dissolve, it also didn't float and clung heavily to the sides of the bowl when he anxiously tried to flush it to start cleaning up.

He wanted to investigate further but knew he'd already spent a lot of time in the stall and if he cut too far into lunch his friends or someone else might start asking where he was. He was also acutely aware that the bathrooms tended to fill up between class periods so the sooner he could get out of there the better. The rex grabbed a bundle of toilet paper from the dispenser and began quickly wiping up the black goop that didn't land in the bowl. As he crouched down to spot clean the tile Levi noticed that the stall was starting to smell strangely like the gloves his dentist wears when he goes to get his teeth looked at. There wasn't time to worry about that, though.

Levi wiped off what he could of the slippery residue from his hand before quickly pulling his pants back up and retracting his slightly firm shaft. He put his backpack on and exited the stall, stopping at the sink to finish washing up.

The young rex checked his watch. It was almost lunch time. He decided to head down to the cafeteria early to meet everyone there. As he made his way through the halls Levi struggled to piece together in his head the changes he was going through to make sense of them. The ball he found? It was rubber, black rubber. Something got on him and turned a very delicate part of his body black and afterward he remembered finding the crumbled up “shell” of something in his pocket. It had to be the ball, there was something in it? He'd already figured that out, but it didn't explain much else. He didn't know why that part of him was growing in size so drastically though, or why it felt so good to touch... or why it smelled like rubber.

In a vague sense Levi knew all of these things were linked somehow, but he didn't know in what way. Worst of all he knew he couldn't ask anyone either. As the rex continued his trek he stopped to awkwardly adjust himself. He could feel his swollen balls pulsing and throbbing ever so slightly.
