Summary
     So it turns out Kuroko’s an Elvis Abomination. Taiga dates him
     anyway.
     “Kagami-kun, it’s Eldritch Abomination,” Kuroko says.
Notes
     Written in roughly 30 hours in honor of Cephalopod Week (even though
     Kuroko's not a cephalopod here, he just has tentacles). For
     Everbright, who asked for "Consentacles! Like, where that's the plot.
     The tentacle monster refuses to get on with it until consent happens,
     other chara confused but [gung-ho]. They're willing but didn't
     realize this was such A Thing for tentacle monsters"
     Timestamp is post-series, probably somewhere Kuroko and Kagami's
     second year? Tagged as underage because Kagami, at least, is
     seventeen, and therefore underage in parts of the world, better safe
     than sorry, etc.
     Unbetaed, abandon hope all ye who enter here, all errors are mine.

They’re shirtless and sweaty and things are just about to get really good if
you ask Taiga when Kuroko pulls away from kissing him abruptly.
“Kagami-kun,” Kuroko says, all sweet blue eyes and his steely mouth red and
wet, “Is this okay?”
One of his tentacles is sliding cautiously into Taiga’s shorts, curling around
his hipbone.
Taiga looks up at Kuroko, who’s straddling his waist, elbows on either side of
Taiga’s head. Taiga has both hands down Kuroko’s shorts already, gripping his
ass (small but firm and round and really nice,Taiga’s definitely into it).
“Um,” Taiga says, and goes to pull his hands out. Maybe he should have asked
before he did that. They’ve never gotten this far before, and Taiga sort of
assumed they were on the same page, but maybe--
Kuroko makes a small, displeased sound.
“It’s fine,” Taiga says. “Did you want me to--” Before he can finish, there are
two more tentacles wrapping around his forearms and gently urging Taiga’s hands
down his shorts again.
Kuroko’s tentacles are usually dry and smooth, matte like the skin of a peach;
they’re a soft, sky blue a shade pinker than his hair. Taiga’s grown used to
them making an appearance when they’re hanging out, way before they started
dating. In fact, when they’re kissing they’re surprisingly absent, even if
moments before they were affectionately holding Taiga in place while Kuroko
studied on the couch and Taiga read Sports Illustratedsitting on the floor,
leaning against his thigh. He doesn’t mind them too much; sure, it’s probably a
surprise to anyone when your best friend reveals he’s got a mass of
interdimensional tentacles, but they’re very...Kuroko--though far less likely
to appear out of nowhere and scare a year off his life--and that’s all he
really can say about them.
This is the first time one’s shown up while they’ve been making out, and
Taiga's a little surprised it’s taken this long. After all, when you start
dating a guy with tentacles you should probably expect them to make sexy
appearances, right? But they’ve been pretty absent most of the time. Taiga was
starting to figure maybe all the masses of weird tentacle porn had it wrong and
they were actually not meant for sex at all, but now he’s going to have to
reassess again. The tentacle easing its way into his pants doesn’t look any
different than the dry ones that have appeared in the past, but it’s slick,
leaving a trail of something that feels like saliva along the line of his iliac
crest, and outright wet at the tip, oozing like a cock. The two around his
wrists loosen when Taiga grips Kuroko’s ass again, but they’re damp too.
Kuroko ducks back in to kiss him again. He’s rocking against Taiga, hard
between them. Taiga’s hard, too, and he’s torn between shifting so he can grind
his dick against Kuroko’s or keep kissing him. Or he could--
He rolls Kuroko over, grinning down at him when Kuroko makes a surprised noise.
One of the tentacles loosely wrapped around his arms tightens around his wrist,
getting wetter. “Hey,” he says.
Kuroko smiles. He’s got both hands wrapped around Taiga’s biceps, but another
tentacle is curling around the back of his neck. “May I?” he says.
Taiga’s not sure what Kuroko’s asking for, but he says “Sure,” and the tentacle
pulls Taiga down so that Kuroko can kiss him.
This is better, Kuroko linking his legs around Taiga’s hips and rocking up into
him while they kiss. Kuroko’s sweaty and making little hungry noises into
Kagami’s mouth, and the tentacle that pulled him down is smoothing its way down
his back, feeling each knob of his spine, the tip getting wetter and wetter as
it does. The tentacle in his shorts is rubbing slickly along the crease of his
thigh and hip, and Taiga is starting to lose track of how many there are.
“Kagami-kun,” Kuroko says breathlessly, tearing his mouth away from Taiga’s.
“Is this okay?”
At first Taiga’s not sure what he’s asking about--everything, frankly, is okay,
Taiga is seventeen years old and horny--but then he notices another slick
tentacle dragging across his ribs, wrapping all the way around his torso once
before brushing an areola, and Taiga’s never deeply considered his nipples but
why not? “Sure,” he says, and the wet tip of the tentacle touches his nipple,
delicate, and he shudders. Maybe he should have considered his nipples before.
Kuroko’s face is that face he makes when he’s deeply concentrating; the one
that looks bland but is really Kuroko’s emotions running deeply inside him,
like that quote about slow rivers or whatever. Taiga likes it when Kuroko looks
at him like that, like Taiga is something to be focused on, like basketball. He
leans down and touches his own thumb to Kuroko’s nipple, experimental.
Kuroko’s eyelashes flutter, and he sighs. His hips jerk into Taiga’s. All the
tentacles touching Taiga--five, maybe?--tremble a little.
“Hey,” Taiga says. “Where do they come from?”
“I told you,” Kuroko says, letting go of Taiga’s shoulder to wave a hand. “A
rift in the--”
“Blah blah Einstein Elvis sci-fi bullshit,” Taiga says. “I got that much.”
“It’s Eldritch,” Kuroko says, almost pissy.
“Whatever. No, I mean, where on your body?” Every time Taiga tries to think
about it, or look for some patch of skin they might be protruding from, he sort
of gets a headache.
“Um,” Kuroko says. “Most of them, if I tried to explain, your brain might
literally come out your ears.” He’s turning pink. It’s cute. “But there are
some here.” He holds out his wrist, which looks perfectly normal, other than
how it’s paler than the rest of him because Kuroko wears his sweatbands so
often. But when Taiga touches his hand, three or four tentacles, much smaller
than the others, twine their way around his fingers.
“Wow,” Taiga says, twisting his fingers to link with them. They’re that same
pink-edged blue as Kuroko’s other tentacles, but much wetter, and Kuroko’s
eyelashes flutter again as his whole body shivers. They’re still pressed hip to
hip, and Taiga can feel Kuroko’s cock twitch.
“Oh,” Kuroko says, almost a moan. “Is that okay?”
“It’s hot,” Taiga says. He strokes one of the little tentacles with his index
finger, and Kuroko’s hand squeezes his bicep as Kuroko’s tentacles all tighten
down on Taiga at once, like they respond to his actions. “You don’t have to
keep asking.”
“I do,” Kuroko says firmly. “Because--” he pulls his hand away from Taiga’s,
tentacles sliding out of his grasp--”You don’t have any idea--”
“Well, obviously,” Taiga says. “They don’t teach you about safe tentacle sex in
health class in America, and I only learned how to put condoms on bananas, so
no, I don’t know, but I kind of signed up for you to show me.” Kuroko blinks up
at him, once, and Taiga feels himself flush. “I mean, if you want.”
“You’re sure?” Kuroko says, cautiously. The little tentacles at his wrists are
twining around Taiga’s fingers again, and now there are some coming out of his
other wrist to wrap around his upper arm and shoulder, and Kuroko’s hips are
making tiny, abortive moves against Taiga’s, and his eyes are slowly dilating,
pupils getting larger and…blacker?
His lips are so swollen and red and still shiny with spit. Taiga’s kind of
nervous but he’s pretty sure you’re supposed to be nervous the first time you
bone someone you really like. “Why wouldn’t I be?” he says. “It’s just you.
You’re not gonna hurtme.”
The world shifts suddenly as Kuroko rolls them back over. “I could,” he says,
and there are suddenly a lot more tentacles, leaving wet trails on his ankles
and shins, coiling under his shoulders, urging his legs open. Kuroko’s eyes
are--strange, pupils huge and darker than black, the blue of his irises
bleeding into his sclera. There’s a weird, almost scary feeling, like Taiga’s
about to tip into a huge, empty void, something he should be afraid of, but one
of Kuroko’s hands has twined with one of Taiga’s and the little tentacles of
his wrist have bound them together. It’s cute. “I don’t want to hurt you,
Kagami-kun, but I could.”
“Yeah,” Taiga says, and reaches up to cup his hand around the back of Kuroko’s
neck, “But you won’t, right?”
“I can’t promise anything,” Kuroko says. “People hurt each other sometimes.”
“That would happen without the Elvis tentacles,” Taiga says.
Kuroko sighs. “Kagami-kun, it’s Eldritch.”
“Whatever.” Taiga squeezes Kuroko’s hand. “Look, I’m pretty sure you’re not
gonna murder me with your, uh.” He takes his hand off Kuroko’s neck to gesture.
“Your everything, and the rest of it can wait for when we’re not trying to
bang, right?”
There’s a little smile playing at the corners of Kuroko’s mouth, and then he
laughs, and Taiga pulls him down for a kiss.
“I’m gonna,” Kuroko says, and there are tentacles pushing his shorts down, and
maybe Kuroko’s as well. “Is that okay--”
“Please,” Taiga says, and then Kuroko is gloriously naked, even if there’s a
whole lot more of him than Taiga ever really expected, because there are so
many tentacles, and they’re all pretty interested in him. There’s one gently
wrapped around his neck, somehow nonthreatening, tipping his face up to
Kuroko’s, its tip leaking against his jaw, and when their cocks--Kuroko’s might
be just slightly...bluerthan average, but appears pretty normal--touch, Kuroko
shivers, and Taiga feels the tentacle at his jaw spurt a little, its secretion
leaking down his throat, pooling in the hollow between his collarbones.
Taiga sniffs. The tentacles just smell like skin, like Kuroko and a little
salt, and he turns his head and licks.
“K-kagami-kun,” Kuroko stutters, shivering, and the tentacle tastes like
Kuroko’s mouth but a little saltier, like Kuroko after they’ve been on a run in
the summer, even as it spills more of whatever it’s leaking into Taiga’s mouth,
and he sucks, and Kuroko--whines, almost, a strange harmonic sound Taiga
feelsmore than he hears, and he looks up.
Kuroko’s face is flushed, even the tips of his ears red, and all the white has
bled from the sclera of his eyes so they’re just blue and that weird too-black,
and his bottom lip is tucked between his teeth, and Taiga’s suddenly waycloser
to coming than he thought he was.
It’s not like anything Taiga’s put in his mouth before, and it’s not quite like
a dick, either, he doesn’t think; the tentacle tapers slightly, smooth and
veinless, with no head or foreskin. It’s cooler than Kuroko’s skin, just
slightly, but it tastes the same, and the liquid oozing out of the slit at the
tip of the tentacle tastes mostly like clean sweat, even as it leaks more and
more copiously into Taiga’s mouth.
“Kagami-kun,” Kuroko says, almost keening, still with that strange echo.
“Kagami-kun, may I please--”
Taiga gives him a look, because for fuck’s sake, they just talked about this,
and nods, taking in a little more of the tentacle, and then he’s being--
manhandled--tentaclehandled--so Kuroko can wrap his free hand around both their
cocks, the tentacles growing from his wrists filling the spaces his hand can’t,
wet and a little cool and slippery, and Kuroko’s eyes fall shut. His lashes are
long, a shade of blue darker than his eyebrows, and they somehow look obscene
as they shiver against his flushed cheeks, and Taiga groans around the tentacle
in his mouth and feels his hips jerk against Kuroko’s grasp.
The tentacle pushes its way further into Taiga’s mouth, pushy but considerately
pushy, like Kuroko, who would never admit to being a pushy asshole but is
undoubtedly one. It bumps up against the back of his throat, and Taigs gags,
and then swallows a little, and his head is being pulled back so there’s
suddenly a little more room, and he swallows again, the tentacle sinking
deeper. It fucks his mouth, cautious, almost gentle but not quite, and it feels
like there’s a mass of tentacles squirming between his legs, not just stroking
his and Kuroko’s dicks but playing with his balls, pressing wetly behind them,
sliding against his skin, and Taiga grips Kuroko’s waist with his free hand and
uses what little leverage he has to rock into Kuroko’s grasp, and his dick
twitches. He moans, most of it muffled, but Kuroko gasps, like he can feel it.
“Kagami-kun,” Kuroko says. “Kagami-kun, Kagami-kun--I’m going to--” and Taiga
doesn’t really know how to say go for it, that sounds awesome with his mouth
full so he makes what he hopes is an encouraging sound. Kuroko’s hand speeds
up, and the tentacles that have basically tied their joined hands together
tighten, and then Kuroko’s coming across Taiga’s stomach, his tentacles
spurting little echoes of fluid all over the both of them and down Taiga’s
throat. He chokes a little, but it’s not any different than what it’s been
leaking all along, not as thick a consistency as jizz, and not an overwhelming
amount. Kuroko slumps down on Kagami’s hips, his hand still jerking both of
them, wringing the last few drops of come from his dick, his mouth parted and
gasping, lips swollen, and Taiga reaches up and manages to get the tentacle out
of his mouth.
“C’mere, c’mere,” he says, hoarse, and Kuroko comes down to kiss him, and one
of the tentacles presses at his perineum and Taiga comes too, the the tentacle
he just sucked still stroking gentle along his jaw while he kisses the breath
out of Kuroko’s mouth.
--
Ultimately, it’s a lot less messy than Taiga expected. Cautious reading of
tentacle hentai--purely for research purposes--had definitely lead him to
believe he’d have to worry about property damage, or at the very least airing
out his mattress, but once they change the sheets it’s fine.
“Kagami-kun, since when has manga ever represented real life?” Kuroko--now
looking as small and human as he ever does, tentacles tucked away in their
pocket of spacetime or whatever--says, when Taiga tells him this as he puts the
sheets in the hamper.
Taiga opens his mouth, looks at Kuroko, and closes it. “It’s not like I had
anything elseto go off of,” he says.
“You could have asked.”
Taiga feels his face get hot. He couldhave, yeah, but every time he thought
about it his voice caught in his throat. “Sh-shut up.”
Kuroko does, but while smiling that dumb smug smile of his. His cheeks are
still pink. God, Taiga likes him a lot.
They stand in front of Taiga’s closet for about three seconds too long, and his
stomach grumbles. Kuroko laughs, surprised, though given Taiga’s appetite he
probably shouldn’t be.
“I’m hungry too,” he says.
“Come on,” Taiga says gruffly, stepping to the door and holding out his hand.
“I’ll make us something to eat.”
Kuroko takes his hand, and one of the small tentacles from his wrist twines
around Taiga’s forearm. It surprises him, so much he stops to glance at it, and
Kuroko shoots him a worried look. “Is this okay, Kagami-kun?” he asks.
It surprised him, but it wasn’t bad, really. It was just Kuroko, who should be
used to surprising people by now. Dumbass. Taiga flicks him in the forehead,
and Kuroko blinks. “Idiot,” Taiga says, unable to hide his fondness, and drags
them to the kitchen.
