“¥10 Ali-yens: Gachapon Goo" by bya

As the classroom bell rang signaling the end of the school day Shilo happily grabbed his book bag and joined his classmates as they headed out behind the school to be picked up. The young green dinosaur eagerly waited for the familiar sight of his mom's silver car so he could toss his bag into the trunk and ride home. Today however, Shilo's mom had an errand to run at the grocery store meaning he was along for the ride and was probably going to miss one or both of the shows he liked to watch after school. Shilo was frustrated, but really didn't have a say in the matter. While waiting in the checkout line the boy nudged his mom and pointed over to the row of capsule toy machines and asked if he could get something from one of them. Initially she said “no”, though when Shilo asked a second time she again relented but still gave him a 10 yen coin which limited his options considerably.

Shilo walked over to the capsule dispensers and gave them a glancing over. All of the machines on the top row were 50 yen so they weren't worth checking out as was the sole 100 yen machine standing by itself next to the rows of cheaper dispensers, only the ones on the bottom that accepted 10 yen coins were possible options. Shilo furrowed his brow slightly before settling on the machine that contained capsules of neon green toy slime. He placed the coin into the slot on the front of the dispenser and slowly turned its handle clockwise. The machine clicked loudly and the capsules inside shifted around as the inner dispensing mechanism rotated to collect one of the balls on the bottom. A metallic clink soon followed prompting Shilo to open the little metal door covering the prize chute to retrieve the capsule of slime inside.

He hurried back over to his mom who was finishing up paying for the groceries and collecting the bags. Together they walked out into the parking lot, loaded the bags into the trunk of the car, and made their way back home. Shilo was able to catch the last few minutes of one of his shows and afterwards retreated to his bedroom to diligently work on his math homework. He hated doing math but he knew when his father got home from work and everyone sat down for dinner he'd be asked how his studies were going and if he wasn't keeping on top of his assignments he'd get into trouble again.

The afternoon slowly turned into evening. Shilo finished up the last few problems of his homework a few minutes before his dad arrived home. He went out to the living room to greet him and not long thereafter dinner was ready, made from many of the things Shilo's mom had bought at the store earlier that day. After dinner Shilo changed into his pajamas and decided to spend the rest of his evening playing with his action figures in his bedroom. Shilo had an entire storyline in his head where his army soldiers were fighting off an alien invasion, though since Shilo only had two alien toys he made up a story about the aliens brainwashing a bunch of other toys so he could use them in the battles too. This was also an opportunity for Shilo to use the new slime he got out of the capsule machine after school.

Shilo dug around in his backpack until he found the capsule and pulled it out. He gently squeezed the plastic ball in his hand until the two halves separated with a light pop. Curiously, the boy pressed his finger into the mass of green ooze in the plastic shell. His finger dipped into it easily and left an indentation on the surface that slowly rose back up to reform evenly. He flipped the shell over the palm of his hand and squeezed its sides while shaking it until the entire mass of slime plopped down into his open hand. The slime felt slightly cool against the dinosaur's skin and immediately began pooling in his palm and creeping toward its edges. He squished and stretched it in his fingers for a few moments as its slick texture amused him before he dropped the slime onto one of the soldiers who'd had the misfortune of falling into one of the aliens' newly devised slime traps.

Shilo continued to play with his toys for a few more minutes until his mom appeared at his door and cracked it open slightly.

“Shilo, it's getting close to your bedtime,” she said. “Time to brush your teeth.”

“Aww mom, do I have to?” Shilo complained.

“Yes sweetie, it's a school night. The weekend is almost here and then you can play with your toys as long as you like, but for now it's time to go to sleep.”

Shilo huffed lightly and set the action figure he was holding onto down. He would have to wait until tomorrow to see if the soldier's squadmates would be able to rescue him from the evil aliens' slimy grips. He walked to the other door in his room that led to the connecting bathroom and dutifully brushed his teeth, rinsed his mouth out, and returned back to his bedroom where he saw that his mom had turned off the lights for him. Slowly, he climbed into bed and got situated under the covers. A few moments later his mom checked on him again.

“Goodnight Shilo,” she said from the open door with a smile.

“Night mom,” he replied.

Shilo's mom quietly closed the bedroom door and made her way back to the living room.

Several hours passed. It was after midnight and the house was silent. Shilo's parents had gone to bed a while ago and Shilo had laid down a couple of hours before that. Everyone was asleep with the exception of one peculiar occupant. The mass of green slime that was covering the toy soldier quivered slightly and shifted in place as it slowly came to life. It had actually been alive the entire time, though it was simply dormant until it sensed that it was safe to move around and explore its surroundings. The ooze collected itself atop the action figure and raised a thin tendril into the air as if it were attempting to sense what was in the room. Shilo's scent hung heavily in the bedroom considering he spent a lot of time in there touching everything but after a few seconds of sensing the room the slime began moving in the direction where Shilo's scent was the strongest: his bed.

It took the ooze a sizable amount of time to move from the center of the bedroom over to the legs of the bed, and a while longer for it to find one of the legs on the corner and climb up. Eventually though it reached the top of the mattress and slid under the blanket toward Shilo. The slime followed along the inside of the boy's leg until it reached the bottom of his pajama shorts and began creeping inside of it. After moving several inches further the goo reached the band of elastic at the bottom of the dinosaur's underwear. Shilo's scent was practically assaulting the slime at this point so it knew it was getting very close to its target. Carefully, the goo nudged the elastic of the boy's underwear aside and began flowing up behind the fabric.

As the goo reached the boy's groin it began to creep over to his crotch finally reaching the source of the young dinosaur's alluring scent. The green slime slowly enveloped Shilo's tender sack probing and feeling it all over. As the slime continued to explore Shilo's private parts it dipped into his sheath and began pooling inside of it covering and surrounding his soft boyhood. Seconds later the slime found Shilo's slit and probed into it pushing a tendril of itself down into the boy. The slick slime effortlessly slipped down into the dinosaur's shaft spreading out his urethra and causing the boy to stir slightly in his sleep and shift his legs.

The slime pushed down beyond the base of the boy's shaft and split apart, one tendril each darting down Shilo's organ and reaching his balls. His immature body offered no resistance to the invading slime whatsoever and as the ooze pushed into his undeveloped orbs they were immediately corrupted by its presence. The green goo continued to flow down into the boy, its outside mass shrinking smaller and smaller as more of the organism flowed into the young dinosaur and mutated his body. As the last little bit of slime slipped down Shilo's member the boy shuddered, his boyhood throbbing several times as his body experienced an orgasm for the first time. A few weak jets of stringy clear pre spurted out from his flaccid member and were caught by his underwear as the boy continued to sleep uninterrupted for the remainder of the night.

At 7:00 AM sharp a familiar cartoon theme song began playing from Shilo's alarm clock rousing the boy from his slumber. Shilo groaned as he awoke and reached over to the clock to turn the alarm off. He sat up in his bed and as he reached for the edge of his blanket to pull it off of him he realized something was wrong. As he removed the blanket he looked down at his crotch and pulled his pajama shorts aside to see that the front of his underwear was wet.

“Oh no...” Shilo muttered as he realized what had happened. 

It had been a good few years since the last time this happened and Shilo thought he was over it, but apparently not. It was only a little bit though and it didn't seem to really get onto his pajamas or even his bed so Shilo figured he could just not tell anyone and everything would be okay. He got out of bed and took his underwear off with his pajamas. He bunched the undergarment up and tossed it into the back of his closet for now thinking he'd find a way to better hide the “evidence” when he got home from school and had more time. He rushed into the bathroom to clean himself up. He noticed his nighttime emission was strangely slippery when he washed it off but he didn't have time to think much of it as he had to get dressed and get ready for school. On his way out of his bedroom though Shilo noticed that the blob of toy slime was missing from atop the army figurine where he'd left it the night prior. The dinosaur walked back over to the toys and began sifting through them to see where it went.

“Shilo,” the boy's mom said from the doorway, “what did I say about playing with toys before school?”

“I know mom,” he responded, “but I'm missing something.”

“Well, I am sure it will turn up later. Come on, you need to eat breakfast quickly so you can make it to school on time.”

Shilo sighed and stepped away from the pile of action figures in the middle of his room giving everything one more quick glancing over as he reached the door and headed for the kitchen.

The day as a whole was unremarkable; Shilo went about his schooling oblivious to the fact that his most intimate of places was now harboring a bizarre lifeform that was in the process of taking over part of his anatomy. The dinosaur worked on his studies, ate lunch, and participated in his physical education class just like any other ordinary school day. When his mother came to pick him up from school Shilo asked if they could stop by the grocery store on the way home so he could get another capsule of toy slime, explaining to her that he'd already lost the one that he got yesterday. Since it was a Friday and the whole weekend was ahead she agreed and pulled up in front of the store, handed Shilo another coin, and told him to be quick because she wasn't supposed to be parked where she'd put the car. Shilo grinned as he grabbed the coin and hurried into the store toward the row of vending machines.

When Shilo reached the capsule dispenser containing the toy slime he noticed a significant amount of them were missing even though only a single day had passed. He considered himself lucky to get one of the last ones in the machine. He pocketed the capsule and ran back outside to where his mom was waiting and rode back home.

At home Shilo lugged his backpack in and dropped it off in his bedroom next to his study desk. He also set the capsule of slime next to his alarm clock on the small table beside his bed. Rather than get back into his action figure roleplay the boy instead went into the living room to spend his afternoon playing video games on the family TV. His father came home around the usual time, greeted his wife with a quick kiss, and joined Shilo in the living room where he turned the stereo system on before sitting in his recliner to read the newspaper. Shilo and his father made small talk about the game he was playing and how his day at school was for a while until the evening approached. Around dinner time Shilo's mother entered the living room to round him and his dad up to go out to eat, a usual occurrence on Friday nights for the family.

It was after 8:00 by the time everyone returned home. Shilo drew himself a bath to get cleaned up before his eventual bedtime. Shilo was allowed to stay up a little bit later on Fridays and Saturdays and after his bath he put on his pajamas and joined his parents in the living room to watch a little bit of nighttime TV. The dinosaur's parents were planning on watching a movie that started soon but when Shilo asked if he could stay up to watch it too his father told him it was a movie for “grown ups” and he would be up far too late for someone his age. Shilo frowned but accepted the response and as the show they were watching finally wrapped up he gave his mom and dad each a hug before retreating to his bedroom to call it a night.

Shilo helped himself into his bed and pulled the covers over him up to his chest. He closed his eyes and slowly began to nod off and only a handful of minutes later the young dinosaur had fallen asleep.

A couple of hours passed and the house was silent again. The spherical capsule sitting next to Shilo's clock rocked slightly as its contents gradually animated. The green mass inside the plastic egg shifted in its container causing it to slowly roll forward and eventually off the side of the nightstand. As the capsule hit the floor it bounced slightly and split open in the process, the slime inside tumbling out and landing onto the carpet below. Much like the other slime this one also collected itself into a blob and raised part of itself into the air to sense its surroundings and get an understanding of where it was. Despite Shilo's underwear from the night prior being wadded up and thrown into the back of the closet across the bedroom the ooze was able to detect the soiled clothing and the scent coming off of it, budding sexual maturity with a hint of corruption.

The green slime was able to pick up the same scent much closer to it and much stronger as well from Shilo himself who was sleeping in his bed only a couple of feet away. The goo slowly began to creep along the floor in the direction of the nearby bed following much of the same ground as the first. It too climbed up the corner of the bed and slipped into the boy's clothes by way of the leg hole in his pajama shorts. The goo slipped behind Shilo's underwear and flowed across his tender balls coating them in cool green slime. The organism could tell from the scent of the boy's genitals that he was already a host but also that his sex organs hadn't fully changed yet. Another mass of slime entering his body would expedite the process and by morning the boy's reproductive organs would be completely mutated and producing more of the goo.

The organism shifted upward from Shilo's sack and started filling the inside of his sheath looking for his opening. As the mass pressed against his slit a tendril of it formed and slipped down into his flaccid member. The slick goo inched down the boy's length and eventually reached his ooze-infested balls. The invading slime instantly merged with the mass already inside the dinosaur as it made contact and the remainder of the slime outside started collecting inside of Shilo's sheath.

Meanwhile, out in the living room Shilo's parents were up late watching the movie he wasn't allowed to see. It was nearing its end and it culminated in a big action scene capped off with an impressive explosion. Shilo's father had the surround sound system turned down a little bit given how late it was, though this time it wasn't enough and the sudden boom was so loud that Shilo heard it and woke up. The boy rubbed his eyes and shifted a bit in his bed as he glanced over at the clock to see how late it was. As the rest of his senses gradually awoke as well however he realized something didn't feel quite right on his body. Something was moving around on his crotch, something very strange and slippery.

He pulled his bed sheets off and yanked his pajama shorts and underwear down before letting out a surprised yelp at what he saw. His shallow sheath was filled with bright green slime that also coated a little bit of the skin around it. The boy reflexively everted his semi-erect member which he couldn't actually see because the entire organ was coated in a thick layer of shifting goo that he realized looked exactly like the toy slime he bought at the grocery store. Shilo shuddered as he felt the cool ooze glide along his sensitive flesh and noticed he could also feel it inside of him as well. In a panic he reached for his boyhood and fruitlessly tried to pull the goop off of him and failed as the slippery mass stuck to his shaft and continued pouring down into his balls. He tried to squeeze the base of his shaft where his urethra bulged outward but no matter how he tried to grip his member he could feel the slime inside easily slide past the blockage.

Shilo withdrew his hand and watched in nervous silence as the mass of green slime gradually dwindled in size as his boyhood greedily swallowed more and more of it. The boy gasped as the last little bit of visible ooze disappeared down his shaft. The dinosaur groaned lightly and cupped his balls. Through the skin of his sack he could feel them throb and churn as the slime inside filled them out completely and then some. Without warning a feeling of urgency hit the boy followed immediately by a wave of intense pleasure as he experienced an orgasm much stronger than the first and this time while he was awake. The young dinosaur whimpered and moaned as his boyhood flexed powerfully releasing several thick jets of green-tinted clear fluid that splattered across his pajama shirt.

The sudden intense rush of a climax dazed Shilo. He felt totally spent and laid in his bed as the afterglow of sexual release radiated through his body. The dinosaur took in a deep breath as he tried to compose himself but doing so only served to relax him further and after a couple of minutes of enjoying the warmth flowing through him he inadvertently fell right back asleep, pants down, bed sheets off, slimy mess on his shirt and all.

The next morning Shilo awoke without the help of his alarm clock as it was Saturday and he was free to sleep in a little bit. As the boy slowly came to he rubbed his eyes and attempted to grab the edge of his blanket to move it off to the side only to discover that he wasn't under his blanket. Not only that, he realized his pajama shorts and underwear were pulled down a bit too. As he pulled them back up and sat up on his bed the events of the night prior slowly started coming back to him piece by piece. It felt like a blur but as Shilo swung his legs over the side of his bed to stand up he glanced at the ground and saw the two halves of the empty capsule that the second blob of toy slime he got yesterday came in. Again, the slime was missing.

Puzzled, Shilo hopped off of his bed and made his way into the bathroom. As he caught his reflection in the mirror he noticed the mess on his pajama shirt. He tilted his head all the way down and pressed his chin against his chest to look down at it and get a closer view. There were several streaks of something green dried on the garment. The color again reminded Shilo of the toy slime and as he mentally made the connection he recalled something with the goo happening the night prior. He remembered seeing it... on his privates? The thought sounded strange to the boy but then he remembered he did just wake up with his pajama pants down and with weird green stuff on his shirt.

Nervously, the boy pulled his bottoms down to inspect himself. As his underwear gave way and allowed Shilo's genitals to hang on their own he immediately noticed something about them felt different, namely his balls. They felt heavier, like they had a little more weight to them. Shilo reached down to feel them and realized they also felt noticeably larger too. Each of his orbs had grown in size, now about twice as large as they used to be, and filled out his sack nicely. As Shilo curiously fondled himself he felt his boyhood start to firm up from all the attention. With a gentle flex of his muscles the young dinosaur everted his shaft and watched as his erect pink flesh emerged from his sheath.

Shilo moved his hand up to his boyhood and held it gently, his touch causing the organ to twitch once involuntarily. The boy gasped as the sensation; as his fingers met his member it felt like a weird mix of tingling and a very light tickle. Holding his boyhood always felt a little strange in an unexplainable way but this felt different somehow. His flesh was more sensitive to touch; in a way Shilo thought it even kind of felt good. He squeezed his shaft slightly and ran his fingers along its short length trying to understand what made it feel the way it did now. After a few moments of poking and prodding at his length Shilo noticed a drop of clear liquid pooling around his slit. He touched it experimentally and found that it was quite slippery getting it on his first two fingers in the process.

He resumed touching himself and realized that with his fingers covered in the thick clear fluid the strange tingling increased in intensity. Shilo moaned gently as he felt his boyhood throb in his hand again. As he ran his fingers along his length another drop began to form at its tip. Shilo rubbed it across his sensitive flesh and gradually figured out that stroking the head of his member felt the most intense. He didn't know what he was doing, only that he really liked the way it felt. After a couple of minutes of this Shilo noticed he felt a strange distant urge growing in his intimate parts. It sort of felt like he needed to go to the bathroom, but not exactly that. Curious as to what this feeling was Shilo pursued it and kept running his slickened hand down his member.

Shilo was too focused on this brewing pleasure to notice that he was breathing a little quicker and his heart was pumping blood faster. He let out a few quiet moans as whatever was happening to him intensified until it couldn't climb any more and peaked. The young dinosaur gasped as he reached climax. Shilo's boyhood pulsed in his hand and as he looked down at it his eyes widened as he saw a thick jet of bright green slime erupt from its tip with each successive contraction of his muscles causing another spurt of goo to shoot out of it and land in a small puddle on the tile floor. He recognized it as the toy slime from the capsules but was too drunk with pleasure to care at the moment. The boy continued to quickly stroke his shaft until his orgasm tapered off and he began to go flaccid.

The dinosaur took a moment to recompose himself and leaned against the closed lid of the toilet to catch his breath. He remembered that wave of pleasure as it hit him, he remembered feeling it last night. As Shilo looked down at the blob of slime on the floor that had just come out of his body the mental images of watching the slime disappear into his boyhood came flooding back. It was as confusing as it was frightening, but Shilo realized it also felt incredible. Was the ooze on the floor in front of him the same stuff that he watched enter him last night? Shilo remembered the first capsule of slime had also gone missing, was that inside of him too? The boy ran his hand down to his balls again to feel them in his palm now wondering if they were bigger because that's where the slime was hiding.

Shilo froze for a moment as he swore he thought he saw the slime move. After a few moments the green mass shifted itself a couple of centimeters across the floor and Shilo realized the “toy” slime wasn't a toy at all but was some kind of living organism. He figured he needed to do something about this and keep it a secret so he hurried back into his bedroom to get the empty capsule off of the floor. He returned to the bathroom and crouched down to try and pick up the goo. It was very slippery, more so than it was when he thought it was just a toy he got out of the vending machine, but with some effort he was able to scoop it into the plastic capsule and seal it inside.

He wasn't exactly sure what he was going to do with it, but he had the entire weekend ahead to figure it out.
