'Professor Lee, get down!'
He's late, the communication line is fuzzy, and honestly, there's nothing Mingyu could've done at the moment. They've still got a kaiju to beat, the same one that is wrapping its massive tentacles around the skyscrapers, snapping them like dry twigs; Mingyu is in his mecha Zord form that renders him unable to just sweep the tiny professor off the roof of the building before the kaiju hits him with an avalanche of purple mucus.
It's not erodent at least—the professor doesn't cease to be in a puddle of goo. He just stands there covered in slime from head to toe, soggy and confused like a victim of a roadside wave, or of a Slurpee machine exploding in his face.
'...Professor?' Mingyu enquires cautiously. 'Are you going to be alright? Please come back to your lab. You can help us from there, no need to put yourself in danger like that.'
Professor Lee staggers to the rooftop exit. So small from Mingyu's vantage point up in the air. Admittedly, Professor is of below average height even when Mingyu is standing face to face with him, out of his mecha and in his ordinary ranger suit. What Lee Jihoon lacks in height, however, he makes up for in smarts—Professor Lee's probably brainier than all of the rangers put together.
It's difficult to keep this in mind at the moment as Mingyu watches him retreat, like a snail leaving behind a trail of purple slime. Mingyu feels sorry for him, and a couple of minutes later when the outcome of the fight is tipping in their favour, he calls Professor Lee on the intercom.
What comes through is unintelligible garble—the kaiju's discharge has likely damaged the electronics.
'Kyeom! I'm gonna check on Professor Lee, will you manage without me?'
Mingyu focuses his sights on the Yellow Ranger's Zord dealing with the kaiju.
'Go ahead. I think we're almost done here.' The kaiju lets out a pained screech that tears through the intercoms and has Mingyu wincing.
And so, Mingyu lands his Zord onto the rooftop and runs to Professor's lab.
The state the lab is in makes Mingyu tense up at the threshold. There are signs of struggle with the office chair that has rolled to the center of the room, vials and graduates swept from the tables and scattered as shards across the floor. Some of the shards are floating in the puddles of thick purple mucus.
'Professor?'
No response.
Out of the corner of his eye, Mingyu catches movement. Something fast slithers across the floor, and Mingyu's first instinct is to throw himself forward to catch it.
A purple slimy tentacle writhes in his grip, lashes wildly, and eventually breaks free, slapping Mingyu across his torso before it retracts somewhere deeper into the dim room.
Oh no! Professor Lee is in danger!
There have been known cases of kaijus turning out to be female and having babies running amok. And baby kaiju can be deadly too, despite their size. Mingyu shudders at the mental image of Professor Lee being suffocated to death by a bear-cub-sized octopus monster.
'Professor!' Mingyu yells.
—only to have a tentacle hit his face, awkwardly as if it bumped into him by accident, and then wind around his head, muffling him, the rubbery texture of the appendage bizarre against Mingyu's lips. Each of the sucker cups moves, and the sensation is a bit like the tentacle is feeling out Mingyu's face in the dark. Mingyu tries to fight it, but the appendage is strong, unyielding. Mingyu is lucky the thing hasn't popped Mingyu's head like a watermelon by now.
'Can you stop shouting please?'
Lee Jihoon's voice sounds fatigued, quieter than usual. Mingyu strains his ear to determine the direction it's coming from.
'Oh, oh wait, this is not right.'
The tentacle unwinds, and Mingyu breathes in the air he has started to miss. He braces, alert, looking all around for an incoming attack.
'Professor, there's a baby kaiju in your lab. Be careful. I can't see it but it's there and it's dangerous. Thankfully, it's not that big. I can take it on alone.'
'Not that big, my ass.'
For a moment there are sounds of hampered movement, groans, and at last, the sound of an office chair rolling across the floor.
Mingyu recoils.
'Behold the ghastly beast,' Jihoon—or what has become of him—announces with a sour face. Jihoon is perched on top of the chair seat, but calling the act sitting would be incorrect. Seating involves a butt, and Lee Jihoon has got none. He has no legs to build up a butt. Instead, his torso splits at its waist into six purple tentacles barely hidden by the shredded remains of Jihoon's khaki trousers. The tentacles are hanging down from the chair, somewhat miserably lax; the mucus drips into a puddle below where the appendages end. Jihoon's coat is stained purple and just as tattered as his trousers—the sleeves are missing to make way for two more massive tentacles that Jihoon now has for arms.
The rest of him is unchanged. He's still as handsome as Mingyu knows him to be. His eyes are the same behind the lenses of his glasses, same long messy hair getting into his face, now wet and matted with sweat and slime.
'Oh dear,' Mingyu wails, kneeling at the chair and letting his bubblegum pink nanofiber suit get wet, sullied with the mucus. His first instinct is to feel the change with his own hands so he reaches to give the arm-tentacles a squeeze.
'Don't.'
The tentacles wrap around Mingyu's wrists to hold his hands up and away from Jihoon's body. Something in the speed of action, in the force of the grip around Mingyu's wrists, in the assertiveness of Jihoon's split-second decision sends a zap of heat down Mingyu's spine. He stares at Jihoon mutely, mouth agape, eyes blinking in confusion.
'I'm sorry.' Jihoon sighs. 'The whole situation is stressing me the hell out, Mingoo-ya.'
The tentacles loosen up a little and slither up and down Mingyu's wrists, a caress of apology.
'It's…uh…it's okay. But have you even checked what you're dealing with? This… body you've got now?'
'What is there to check?' Jihoon bites. 'I'm a fucking octopus-man now.' He sighs again, dejected. 'I can taste with these.' He lifts one of his legs-tentacles to showcase the inner side of a tentacle where the suckers are located. 'I can literally taste you right now.'
Just a few minutes ago, a tentacle was sliding across Mingyu's mouth.
Mingyu feels the blood rush to his cheeks.
'Can you move?'
'It is an embarrassing spectacle. I'm far from kaiju and they too are not the most agile.'
Jihoon removes his tentacles from around Mingyu's wrists but makes no move from the chair. Mingyu rises to his feet then.
'We need help here. I'm no scientist, and two—or more—heads is better than one.'
'No!'
Mingyu makes one step towards the door when he hears a sound of something wet hitting the floor. Mingyu turns around to Jihoon who is now towering over Mingyu with six of his tentacles wound up and straining to support his body in an upright position. The remaining two arm-tentacles latch onto Mingyu's forearms.
'I will deal with this myself. I just need to calm down first.'
'This doesn't look very level-headed to me,' Mingyu quips, looking at the appendages squeezing his biceps.
'That's what I'm talking about.'
Jihoon crawls back and lowers himself back onto the chair, all eight tentacles loose. Mingyu kneels in front of him again. This time, Jihoon is less jumpy when he stretches out his hand to tug at the tattered remains of his slacks.
'Do you think we should get rid of these maybe?'
Jihoon answers with a quizzically arched brow.
'It's not like you'd be indecent without those, and they barely function as clothes anyway.'
'You just need an excuse to get inside my pants.' Jihoon cackles nervously.
Well, it seems Mingyu's silly little crush hasn't been that well-contained as he hoped it would be.
Jihoon reaches with his tentacle for a scalpel lying on the tray on his desk.
'I can take it,' Mingyu offers to Jihoon's headshake.
'I need to know they're not completely useless for complex motorics.'
A drop of sweat trickles down from his hairline as Jihoon stretches the appendage towards the handle of the scalpel. Gently, he manages to pick it up, the thinner end of a tentacle curled around the handle. Jihoon drops it in Mingyu's open palm.
'Go on.'
Mingyu cuts the rags off of Jihoon.
Maybe he was too bold with his statement. Despite Jihoon's lower body presenting as a mass of tentacles, without the clothes, he's still very much naked and looks so much more vulnerable, in line with his current emotional and psychological state.
Mingyu makes a fair attempt at not ogling but eventually his eyes still linger on the part where Jihoon's flat pale stomach first goes blotchy with purple and fully morphs further into the bunch of thick slimy tentacles.
'So like what's the deal with the—' Mingyu stops short. 'All that? Do you still have your—?'
'I'm stuck in a state between a mammal and cephalopod, and you wonder if I still have a dick?'
'Do you not?'
Jihoon grows silent.
'I did wonder.'
'Is it under there?' Mingyu nods towards the limbs.
'It's one of these actually.' Jihoon lifts one of the tentacles.
'Sick!'
'I'd rather have my regular dick back, thank you.'
Jihoon makes a move to lower the tentacle but Mingyu intercepts.
'It doesn't look any different to me.'
'Do you comprehend that you're essentially—'
'Holding you by the alleged dick?' Mingyu asks, grinning. 'But how do you know?'
'It's different from the rest. Here.' Jihoon shows the dick-tacle, inner side facing Mingyu. The last segment of it is missing suction cups and is shaped a little oddly, spade-like.
Mingyu hums and rubs his chin hoping to come off as a scientist type.
'So like, do you cum only with this one here? What about the rest? In hentai—'
Jihoon slaps his forearm with the nearest-to-Mingyu tentacle, which by coincidence happens to be the one they've been inspecting.
'You can't seriously be this cum-brained.'
'You can't blame me for asking when you're waving your dick in my face.'
The tips of Jihoon's ears grow a violent shade of pink.
'Cumming with all of these seems like a bit of overkill,' he mumbles.
'Well, that's how hentai is, I guess.' Mingyu shrugs. 'But then again, maybe it's hard to propagate for kaijus, you know, maybe they would go to all means necessary, and—' Mingyu waves his hands around.
'I shouldn't have touched you.'
'What? Why?'
'The slime. It made me go like this, who knows how it'd affect you. Maybe you acting like this is also—'
Mingyu narrows his eyes. 'Acting like what now?'
'Overjoyed by imagining kaiju tentacle sex.'
Mingyu guffaws.
'You think it could be an aphrodisiac? Well, you don't look very up for kaiju tentacle sex.'
'I mean, maybe it affects people differently.'
'Do I look horny to you?'
Jihoon gives him a once-over.
'Maybe. Are you?'
'Well.' Mingyu sighs. 'I don't see many attractive octopi-mermen on a day-to-day basis. I wouldn't be opposed to having sex with one. Consensually while at it. In hentai usually—'
'This is real.' Jihoon's tentacles wind around Mingyu's biceps again and shake him up a little. 'Not some violent porn fantasy.'
Mingyu curses the fiber his suit is made of. Tight already on a normal day, at the moment it is almost punishingly too tight. He clears his throat.
'Aren't octopuses the kind to die after mating?'
'I don't know, are they? I'm a scientist but not a marine zoologist.'
'I don't know, I think I've heard somewhere? What if after mating your octopus part dies? And you turn back into a normal human?'
'Or I just die. Period.'
Jihoon is chewing on his bottom lip, brows furrowed.
'Do you have any better solution for now?'
'I don't.'
Mingyu lowers himself back on the floor.
'I won't ask you to do anything against your will. I'm not even certain this would help, so.' Mingyu shrugs. 'I could just keep you company while you think. You could brainstorm ideas off of me. Either way, less lonely like this, eh?'
He doesn't get to continue his ramblings as Jihoon careens forward, crashing their mouths together. It's clumsy and Jihoon's fringe is in the way, and his body seems to gradually slide off the chair and into Mingyu's lap, but it doesn't bother Mingyu. He kisses back with enthusiasm and reaches to brush Jihoon's hair back from his face.
'Undress,' Jihoon instructs in between kisses.
Jihoon lacks the fine motorics to undress anybody himself but even if he had all his ten fingers intact, the suit doesn't have any built-in zippers—Mingyu flicks a few buttons on his Morpher and the suit deconstructs, leaving him anticlimactically fully naked way too soon. He's sitting with his bare ass on a wet linoleum with a slimy octopus-man in his lap. It's not ideal but it's okay—Jihoon's arm-tentacles writhe up and down his forearms appreciatively while two more shift along his sides to sneak a grope at his back.
Mingyu goes for Jihoon's jaw and neck, nipping, mouthing, licking the skin he finds there as if to get back at Jihoon for wetting him. As he does, he squeezes his eyes shut. Sensory-wise, Jihoon's wriggling is overwhelming. He's a squirming mass in Mingyu's lap, appendages now exploring his body boldly—two more tentacles slither up Mingyu's torso, inquisitive while the rest stiffen to support his body in Mingyu's lap. With all this movement, he must feel Mingyu's hard-on digging into his flesh on the inside.
The tentacles meanwhile reach Mingyu's pecs, and after some aimless caressing, the tips latch onto Mingyu’s nipples with the suction cups engaged.
And then they pull.
Mingyu moans and bucks up, dick bumping into the soft billowy flesh and mixing his own precum with Jihoon's seemingly incessant mucus. He can hear Jihoon laugh—a quiet, amused sound somewhere in the vicinity.
'Okay, you have a point maybe. This can be fun.'
So Jihoon does it again, and again. Until Mingyu is sore and sensitive. Jihoon's tentacles along his back shifted to curl around his waist and support his thrashing as Mingyu humps into him without any restraint or shame.
'Let's get you accommodated like in those pervy cartoons you like so much.' Jihoon chortles.
His tentacles get to work. First, they stretch Mingyu's arms up and bind them together, then they spin Mingyu around to have him kneeling on the floor with his backside facing Jihoon. For the first time in the past hour, Mingyu feels the heat of embarrassment lick at his cheeks. Two tentacles curl around Mingyu's thighs and spread his legs wider apart causing Mingyu to bend at the waist almost instinctively. Jihoon laughs again
'For a Power Ranger, you're oddly eager to go down on your knees.'
With every sweep of a tentacle, more and more of Mingyu's skin becomes slick with the mucus. There's some smeared across his thighs, beads of it on his torso, streaks across his biceps. Wet appendages stick to his asscheeks and spread him for another one to slide in between and writhe against his hole.
'Hhhnggh'
'They're so fucking sensitive you know,' Jihoon says, voice breathless. 'I can feel every twitch of yours.'
'Yeah-yeah, and you can taste me too, I remember,' Mingyu rasps back. 'Wait, does that count for eating out?'
'Don't get too chatty.'
'Yeah, why's that?'
Mingyu counts—it's rather surprising that he can still have a grasp on his surroundings in this state—there's one tentacle around his wrists, two around his thighs, two on his ass, one nearly in his ass, which leaves Jihoon only two tentacles left to support himself. Surely he won't—
A slimy tentacle nudges against Mingyu's mouth.
A miscalculation on Mingyu's part. Or maybe he underestimated Jihoon. Either way, he can't stay silent for long, and as soon as he tries to talk back, the tentacle promptly slides inside.
'Try not to bite, wouldya, Mingoo?'
Mingyu huffs and nods. The sensation of an appendage sliding in and out fluidly is weird but not to the point of being off-putting. So far Jihoon seems to be controlling himself well, not pushing Mingyu over his limits.
The tentacles shift and move along his body to cover more ground. The ones around his thighs retract back, only to have Mingyu jolt when they come back, now to curl around Mingyu's neglected dick and balls.
Jihoon is toying with him, driving him mad before he could fuck him properly. In retaliation, Mingyu whines around the tentacle in his mouth, wiggling in Jihoon's hold to demand attention that he admittedly already receives plenty of.
He comes so embarrassingly fast, nearly as soon as Jihoon breaches him, and at that moment Mingyu is ready to believe that the slime that's everywhere by now was laced with something. His mind is cloudy after he comes for the first time and stays this way throughout. His body is rocking between the three points—the tentacle fucking his mouth, the one thrusting up his ass, and those tugging on his dick and balls, milking him in pace with the other two appendages. His sweat and cum drip down, adding to the puddle he's laying chest-down in. In the corner of his hazy mind, he registers how Jihoon's tentacles shift around to play with his nipples or give some other part of him a squeeze, part-check in, part-affectionate groping.
'...one more?'
'Hhwhh?'
Mingyu makes a questioning noise.
'Do you think I can add one more?' Jihoon levels to look at him, and Mingyu is drunkenly stunned for a moment. So pretty.
'You feel so good I just wanna— If I could squeeze more of myself in.' There's a glint in his eye too. A bit wacky. He slips a tentacle out of Mingyu's mouth and kisses it after. 'Please.'
'I… uh…' Mingyu's voice is lost. 'Fuck, go at it.'
Jihoon does, and Mingyu's voice breaks.
Somewhere in the background, Jihoon curses and mumbles. He falls down, chest flat to Mingyu's back, while the overwhelming rest of him is still moving. Inside Mingyu, against Mingyu. Each of his tentacles wriggles individually, and it is the final straw that breaks Mingyu because actual tears drip down his nose bridge and end in the puddle of fluids beneath.
His orgasm nearly knocks him out. He misses the crucial moment when Jihoon cums too, and he only finds his bearings once Jihoon flops down on the floor beside him. Still no human legs in sight.
Weirdly enough, Mingyu still can feel a tentacle up his ass. And also Jihoon is looking at him all weird.
'You might wanna… uhm. Pluck that out.'
'What?' Mingyu reaches behind and finds a tentacle.
That is not attached to Jihoon's body.
'What the actual fuck?!'
'I guess octopodes lose their dicks after mating.' Jihoon shrugs, face gloomy. 'Which doesn't make me human but makes me one arm short. Not that I think seven of 'em is too few, but you know, eight turned out to be my new normalcy so.'
Mingyu throws the dead appendage away from sight.
'Maybe you lose one after each orgasm? Meaning you should cum seven more times.'
Jihoon arches his eyebrow.
'You think you could handle it?'
'I'm a superhero with magic and stuff!' Mingyu announces proudly.
'Well unless you have a magic superpowered trained hole, I don't think—'
Jihoon cuts short and lets out a pained moan before he curls into himself, all his seven tentacles wrapping tight around his body.
'Jihoon-hyung!' Mingyu scrambles up, uncertain what to do, hands hovering above Jihoon's back. His touch could do harm and he would never forgive himself if it did.
One by one, Jihoon's tentacles shed and shrivel on the floor, revealing his very much human body, one that Mingyu hasn't had a glimpse of before. For a minute he just stays still and quiet, waiting.
And then Jihoon speaks up.
'Hand me over a spare labcoat, would you? My ass is fucking freezing.'
Then Jihoon uncurls to peek at Mingyu who's already getting up on his feet, equally bare-assed.
'Might wanna grab one for yourself while at it, Mingoo-ya.'
