"And the results areeee—"
Four eagerly awaited the moment he could announce that Liy was the one leaving the competition for EXIT.
Just as he was about to say it, X jumped in front of everyone and shouted at the top of his lungs:
"Hi Pie! Bye Liy!"
Everyone blinked, and Four frowned.
His mind quickly filled with annoyed thoughts about his companion.
That blasted variable. Out of everyone, he, as always, had to stick his nose where it didn't belong and ruin the moment! Pythagoras! Four couldn't wait to get a moment alone so he could scold that self-conflicted nuisance.
"Hey! I wanted to say that!" Four growled.
"Well, if you don't like it, just screech me!"
The blue number raised an eyebrow. So now he was pretending not to care about his punishments, huh? Well, Four would think of a much better way to teach him not to interrupt.
And in a fraction of a second, an idea came to him.
Oh...
"Oh. I'll do much worse," he promised.
X ignored the dark look on his companion's face, paying no attention to his words.
The Battle for the Battle for Dream Island continued.
"Hey Four? Where did X go?" Book asked.
Four had to hold back a sinister laugh.
"Limb reattachment center!"
A vague lie, but enough to satisfy the book's curiosity.
The truth was hidden deep within a grove. X was tangled up with his enlarged limbs, courtesy of his partner, who had not hesitated to teleport him to a secluded spot the moment they were out of the camera's view.
Well, it was nothing X hadn't dealt with before. He still believed Four had been worse during his teenage years.
They laughed at the memories.
"You keep laughing at me, HMMMM!?"
"OH! FOUR!" the yellow algebralien exclaimed far too cheerfully, as if he hadn't seen his friend in years.
"It's good to see you! But... why did you bring me here? Ants are poking my bu—"
"Whatever," Four muttered before flashing a smile, clasping his hands together and pacing back and forth.
"You are here because I wanna teach you a lesson!"
"YAAAY! A LESSON!"
Four spread X's legs apart with a predatory look.
"Huuh... a lesson..?" The variable felt his body begin to heat up, a warning sweat wasn't far behind.
The whole number slowly nodded.
"Yes. And I hope this lesson stays in your mind..."
X blinked, shifting uncomfortably.
"Huuuh, who's taking charge of hosting if you're not with the contestants?"
Four rolled his eyes.
"I gave them time to do whatever they like."
An amused smile returned to his lips as he added,
"Don't worry, this will be pretty quick!"
Four moved his face closer to his companion's. X looked uneasy and leaned back. In response, the taller algebralien moved even closer, until he pushed him down and pinned him against the ground.
His breath brushed against the variable's lips as he leaned in and stole a kiss.
Their mouths met awkwardly, complicated by X's attempts to pull away. Four grabbed him by the jaw to keep him still.
After a while, their tongues met when the whole number made sure his companion was no longer resisting, instead moving his tongue to intertwine it with Four's.
That excited him.
Pulling away with a strand of saliva still connecting them, he shifted his hips and settled onto X's thighs, while X continued trying to catch his breath. When he looked up, another kiss attacked him, accompanied by the giggle his companion let out.
“Just a few more kisses and you’ll be ready for me!” Four pressed two fingers against X's already noticeable cleft, eliciting a moan from him.
Well, maybe the punishment didn't sound so bad-
Four hooked his fingers, penetrating deeper and pulling out his two tentacles. A scream escaped from the variable.
Their reproductive organs trembled in the cold, a sun-orange color. What is most striking about the reproductive organs of the algebraliens is that their penises have a multiplication sign marked on them, and their clefts have an equal sign slightly above the beginning of the lips.
“Nuh-uh, you don’t get to enjoy this if it is a punishment!”
In his hand, his partner's sensitive penises throbbed, for they were not yet erect.
“Only I do!” Four smiled, almost innocently, in a soft tone of voice that fooled no one, as he squeezed the glans of one of his partner's dicks.
X rolled his eyes as he gradually became aroused, noticeable in how he slowly hardened.
The number began to caress to accelerate the process. He frowns at a thought.
“Two members huh?! Why not four?” X's blood ran cold.
A snap was heard and suddenly the yellow algebralien had two extra tentacles, his body trembled, he looked up at his companion with fear.
“F-four. . .”
“Yikes! Thia gonna be a tight fit!” The aforementioned would laugh, letting the orange members rest on his belly.
Four did no more foreplay, kneeling with his body pressed close to X's.
Aligning their already swollen entrance with one of the members, they sighed, letting the tip nestle between their lips.
They both closed their eyes with an electric shock running through them.
“Hmmm, not big enough, guess I have to do something about it”
“F-four!”
X stopped him before he could snap his fingers. His companion opened his eyes and saw the anger creeping across his face.
"No?"
X began looking everywhere but at him, nerves mixing with his desire.
"I- Uh, kinda want to take you while being myself..." A blush formed on the variable's cheeks.
Four froze.
He stared at him in silence, watching his co-host swallow nervously.
He should've ripped off one of his legs, but he was far too confused, trying to understand why his face was growing warm at those words.
X did not miss how Four's cheeks turned bluer, almost bordering on a dark purple. Taking this and their stillness as a green light to continue.
He snapped his fingers and his members were once again two, the erection remaining.
X lifted his gaze and slowly brought his hands up to his stunned companion's face.
"Foury..." he said.
There was no response.
"Do you... want me?" he continued. Four's breath caught in his throat.
X was leaning in again, bringing his face closer.
“Y-You are nuts! This is a punishment!” The tallest one grunts, but does nothing to move away, as if struggling only to hide the heat, the moisture in their folds.
“Oh, I see” X snorted with grace, which did not amuse his companion at all, who glared at him.
Okay, X was getting on a high, Four had to bring him down to earth, or he'd end up ripping off his arm.
…
Well, he was going to do it anyway, but he didn't want to get ahead of himself.
He sighed, trying to control his breathing, and decided to improvise; it wasn't so hard to unnerve the variable after all.
“So you’re taking the reins, huh? Then why don’t you keep going, buddy?” They smiled maliciously as they watched the other number's face turn orange, biting his lip.
It's not that X is a virgin or anything like that, it's just that Four is the one who always had control, because yes, they had sex even if, in their eyes, they were just very good friends.
Four always avoids any sentimental conversation no matter how hard X tries, and boy, did he try many times to talk about what they were.
But one thing the number does know is when they feel needy, and that's when they take advantage of X and how the variable treats them.
X lets himself be bitten, ridden, scratched, and squeezed until dawn, enduring everything Four has to give, but when it's his turn to be the one who needs a release, the blue number shrugs and turns his back on him, pretending to snore to stop being bothered.
At a certain point, it became frustrating for X. Not because he was being denied something so unnecessary, but because what he received in return didn't compensate for everything he did for Four.
Well, except for when his friend helped him find his value, years had passed, yes, but deep down he was still grateful.
A blow to his cheek snapped him out of his dissociation, and he saw the impatient face of his partner.
“Ah, sorry…”Before Four could speak, they placed their hands on his hips, causing him to spasm.
“Can I… you know.. umm...” He began to ramble, wanting to make sure Four hadn't changed his mind.
The other one grumbles, exasperated “Do it if you know whats good for you.”
"That's a good statement," thought X, settling down beneath Four. .
“Okay, Then… I-I’m getting inside, it’s that okay?”
Four's blood was boiling for many reasons, and he decided he didn't have time for X's insecurities.
They guided their hand, held X's member and began to go down before the other could let out a peep.
The insertion was slow, Four swallows, the centimeters sliding inside him and filling him.
The variable's eyes widened before turning white, his hands squeezing the body he held above him.
The tip hit bottom.
“MMGHHH- SEE? Its not that hard! But you make it seem like it is the Riemann hypotesis!”
“I don’t want to hurt you, four…”
“Grrr. You are REALLY getting on my nerves now” He raised a hand, about to snap his fingers, with a terrifying look for X.
X reacted quickly, thrusting his hips upwards.
The response was almost instantaneous; Four let out a muffled grunt, and the bumps on his head trembled in what appeared to be a sign of pleasure.
“Ugggh..”
The variable knew he had made a good move this time, and since he didn't want to screw up again, he continued thrusting his hips upwards, eliciting more crooning from his partner.
With each thrust, splashing sounds could be heard, X pounding Four's cunt hard, who unsheathed their claws and scratched their partner's sides.
At some point, sex began to drive them both crazy and they ended up changing positions. The kneeling variant sought to go deeper while his other penis throbbed and rubbed against the soft flesh of Four's ass, who was in his preferred position, on all fours.
“M-Make it quick! I can’t have my contestants waiting so much!” He demanded, gripping the grass between his fingers and letting saliva and sweat run all over his pheromone-scented body.
Luckily for him, X was already finishing up. That's why he withdrew instantly, and at that very moment a scream burst against his face.
“WHAT ARE YOU DOING?! I WAS SO CLOSE! PUT IT BACK.”
Four's hand began to glow as he bared his sharp teeth in a menacing growl.
The other algebraic alien had no choice but to obey, penetrating again and stabilizing his hands on his partner's hips.
Gasping, Four lowered his hand to masturbate his aching penis. X let out annoying squeals, but it filled Four so well that they didn't care.
The air was humid, and the grass beneath them was soaked with the natural lubricant of the numerical beings. With a final sloshing motion, X entered his partner, a knot forming at the base of his member, eliciting pained gasps from both of them.
“Ugh, great, can you move at least?” Four tried to make his voice not waver and sound more enraged.
“Um, okay…”
Then X continued, starting with light, painful, costly thrusts; it was even more so when the number began to receive him, pushing his ass back hard, shouting that he was close.
The knot began to swell, and with that alone the blue being reached their climax, their walls tightening and wanting to milk their co-host.
X's eyes rolled and tears of excitement escaped him; his knot finally untied and jets of sperm spurted against the entrance to the host's uterus (or whatever Four has inside).
Trembling, Four lay on his back and X hugged him beside him, taking advantage of his friend's vulnerability to show him some affection without receiving an uncomfortable look.
They lay there, staring up at the sky through the leaves of the trees, their gazes distant.
"Four... Does doing this mean something to you?"
The question drained the warmth from the moment, and the named algebralien frowned.
"What? We've done this before."
Something clicked in his eyes.
"Wait, don't tell me—you actually believe what the objects told you?"
X quickly looked away, his cheeks turning pink once more.
"Well, it makes sense. Friends don't do the act of multiply on this planet. Only couples do that..."
Four sat up with a slight groan. On Algebralia, multiplying was something couples did, but the act itself wasn't nearly as intimate as people thought. Four remembered that he'd even done it with Two out of pure spite, just to watch the other squirm.
But it hadn't felt the same as when he did it with X.
Still, they weren't on Algebralia anymore, and they had to adapt. That meant changing some aspects of themselves.
Four didn't really care, as long as he could keep being the host of the show.
"Whatever. It's not like the objects would want to watch us do the act of multiply as to correct us"
He said it dismissively, but his more reserved companion covered his mouth with one hand and shook his head.
Huffing at the reaction, the number stood up and snapped his fingers. The liquid dripping down his legs vanished, though he still brushed dirt from his lap with a few pats.
X got to his feet, copied his friend's cleaning routine, and prepared to leave.
He took one step and fell with a small, cute yelp.
He was missing a leg.
"Now, where are you going, little buddy? We're about to play a game!" Four cheered in a sing-song voice.
X tried to push himself up with his hands.
He was missing an arm, too.
"It's called Four Missing Limbs!"
The number waved one of the other algebralien's missing arms.
"I hide them, and you have to seek!"
Four levitated all four of his sidekick's missing limbs. Like streaks of light, they shot across the sky and disappeared into the distance.
Four smiled and looked down at his hands suspiciously.
"I was going to take your eyes off too, but let's say I'm in a good mood!"
Giving a wave, he looked toward the horizon before turning back.
"Got to go! Good luck, X!"
The addressed algebralien remained silent. He looked around for a moment, then lowered his gaze sadly.
He was going to have to roll.
