Summary
     "The worst thing," Karkat states impulsively from his seat on the
     floor, "the worst fucking thing about this is how you always act like
     a smug little bitch even though the only reason you win, ever, is you
     spam the same fucking move a thousand times and trap me in a corner."
     For the kinkmeme: Karkat doesn't believe that Sollux has two bulges,
     but learns about them firsthand.
Notes
     I imagine they're playing Super Street Fighter II, retro style, and
     Sollux is playing in ways specifically calculated to enrage. As
     Dhalsim, for example, he punches and kicks Karkat from a distance,
     teleports behind him once he gets really furious, gives him a noogie,
     then sets him on fire.
     Karkat spends the entire time shrieking and whining that every move
     Sollux makes is cheap bullshit. After each victory, Sollux lets out
     an obnoxious, nasal little "eheheh" that would make anyone want to
     punch him. Most sympathetic protagonists ever.
As usual, the argument begins after a gaming session. This time Karkat starts
in because Sollux is predictably fantastic at fighting games, has just defeated
him soundly for the twentieth time in a row, and the natural response is to
snipe at him to let out a little venom. He knows it's stupid and immature and
both of them will be embarrassed, is pretty sure that in the end Sollux will be
sarcastically accepting his apologies, but the second the console goes off the
words erupt from him anyway.
"The worst thing," he states impulsively from his seat on the floor, "the worst
fucking thing about this is how you always act like a smug little bitch even
though the only reason you win, ever, is you spam the same fucking move a
thousand times and trap me in a corner."
"So now it's my fault you don't know how to block. I can't help that you suck,"
Sollux murmurs passively, getting up from his chair to put away the
controllers. "Or that you're incredibly loud and annoying whether you lose or
win. I just suffer all this for some reason."
"And I can't help that you suck at everything and have to win with cheap moves
and cheating," Karkat retorts. "I just have to suffer because you're a goddamn
unfair lying nooklicker."
"But what good is lying or cheating for things where you actually need skill?"
Sollux asks, eyebrows lowering as he unplugs a controller wire from the fat
grub lounging in front of his television. "I mean you're a shitty gamer no
matter what you do, just like you're a shitty programmer, lying and cheating
doesn't make anything you code functional, so-"
"Oh wow, yet another thing you're an asshole about!" Karkat interrupts as he
jumps to his feet. "Way to stealthily work that in, brilliant segue, you're a
fucking conversational ninja. So what else can you bring up to rub in my face-"
"Jesus, KK, you're...seriously the worst loser!" Sollux exclaims, mood flipping
instantly from passive to aggressive as Karkat approaches. "It's incredible how
whiny you get about inane shit," he snaps, eyes defensively flaring. "If you
put some of the time and effort you put into your constant bitching into
actually improving a skill, just imagine-"
"But why bother when you'll just keep spamming the same fucking move to piss me
off, congratulations, it worked-"
"-I know nature was unkind to you and you're tiny and stubby all over like a
grub, for example," Sollux continues in escalating irritation, "but your
fucking glorious temper and personality really make up for-"
"-Pathetic, you're one to talk, with your stupid obvious lies about how amazing
and doubly endowed you are. Skinny nerdy pompous fucktard-" Karkat adds, but
Sollux lets out a harsh, disbelieving laugh that momentarily silences him.
"So you ask me private things about myself and turn them on me in arguments
later and I'm the pathetic one," he hisses, lightning tangling and knotting
above his head. "I bet you've been waiting perigees to bring up that little
tidbit, you grubfisted douchebag, you're fucking scum."
"At least I'm not a liar!" Karkat retorts, standing on his toes to intrude more
on Sollux's personal space, knowing it makes him uncomfortable. "God," he
continues impulsively, knowing Sollux still has him at a disadvantage, "I
fucking hate you sometimes." His lips draw back from his teeth in something
that is almost a grin as he watches Sollux's eyes widen behind the shades,
recognizing the sudden blackrom overture.
"Not half as much as I hate you, so petty over such asinine shit. It's a stupid
game-" Sollux begins in a cold, shaking voice, trying to end the argument by
returning to the original point, trying to stop it from going too far.
"But you never disagreed when I called you a liar," Karkat interrupts heatedly,
needling him. "I'm right, aren't I? I bet no one ever called your bluff because
no one can look at that hideous thing you call a body without going blind." A
brief thrill of excitement runs up his spine as Sollux bares his sharp teeth in
return. Pushing the psionic far enough to force him to slow down is a victory,
but the anger Karkat evokes makes him want more than anything to push Sollux
further.
"Fine, you want to see? Go on and call my bluff if you really hate me that
much," he snarls, arcs of red-blue electricity flickering between his horns,
"if you're so fucking obsessed, and when you're wrong I'll just show you what I
can do with them."
"Fine," snaps Karkat, sweeping the argument into blackrom with irrational fury,
"you're a stupid single-bulged grubfucking douchebag and your nook's probably
big enough for-"
Karkat's body slams forward against the far wall with surprising force, his
skull striking it with a harsh thud. For a moment he hangs in a daze until a
thin hand slides up the back of his head, tapered fingers curling in his hair
as Sollux lets out a sigh. Karkat starts to whirl around, already snarling and
going for a weapon, but tendrils of red and blue light erupt from the walls to
restrain his limbs before he can turn.
"Wrong answer, KK," Sollux murmurs near his ear, relieved and sedate after the
release of psionic energy. "But you still get a prize. Or, rather, you get two
prizes," Sollux continues, fingers tight in Karkat's hair to keep him staring
forward. "Which is really sort of the point, since there are two-"
"You're really killing the moment," Karkat informs him, then grits his teeth as
the hand in his hair curls tighter and presses his face into the wall.
"Is there anything you don't bitch about?"
"Let me down and I'll write you an itemized list-"
Even though he intends to needle Sollux into action, the electricity that jolts
Karkat's body still surprises him, leaves his limbs jellylike and quivering in
the psionic restraints. It takes a moment for him to understand that his
clothes are torn away. Once the fact of his exposure strikes him, though, the
cold air on his skin and the faint, anxious echo in his bones, he shudders at
the realization of Sollux's power.
"Or I could just shut you up," Sollux murmurs as he releases his grip on
Karkat's hair, loosening the bonds. Flickering light encompasses Karkat's
frame, lifting and twirling him lazily in the air as he flails his limbs to
seek something solid; tendrils wind again around his wrists and ankles to pull
his back against the wall, letting him face outward. The colorful light is
solid but uncannily textureless, conveying no sensation but gentle pressure.
"Impressive?" the psionic asks, still fully dressed, mouth curving crookedly in
the same familiar smirk.
"Yeah, tho athtonithing," Karkat lisps irritably, trying not to sound nervous
or awed.
"You're such an asshole sometimes," Sollux remarks in irritation, moving his
hands to flood Karkat's mouth with red light, pressing his tongue to his
palate; a vibrating shock courses through him as he reflexively bites down,
jolting his body roughly against the wall. He hangs dazed for a moment in the
restraints, already painfully hard, tongue and gums throbbing around his teeth.
"Wow, you're really turned on. Pretty fucked up, KK, you like that? So where
else can I put it?"
"Unnnnn," Karkat whines as psionic energy floods his nook, buzzing faintly, and
begins to expand as the force in his mouth diminishes. "Oh - oh what the fuck!"
he snaps, voice going high and uncertain as it starts, slowly, to stretch him
wider.
"Be glad I'm so charitable, doing all this gives me headaches. But I'll need
room for both of these," he continues, continuing the slow expansion of psionic
force as he takes off his own clothes. Karkat notes bitterly despite his
distraction that Sollux turns around with strange modesty before stripping off
his shirt and shucking the baggy jeans, kicking them into an untidy pile. His
body is as lanky as Karkat expects, all gangling limbs and sharp angles, but as
he turns back with a victorious smirk Karkat sees immediately that he never
lied.
"Oh my god," he says in a strained voice as he stares at the hard bulges
between Sollux's skinny thighs, one behind the other, a single set of shame
globes behind them. "Powers and extra horns and this, what the fuck-"
"And bipolar disorder, insomnia, lisping, migraines, the screams of the
imminently deceased. I'm so fucking fortunate." Sollux approaches the wall.
"And here's your chance."
"For what," Karkat answers as levelly as he can with the light still growing
inside him, so slow that even though he has never been so stretched and full
the feeling is more surreal than painful. His strained body reflexively
tightens when he thinks about it, a whine escaping from his mouth as he grits
his teeth.
"To back out. Or do you really want these inside you?" Sollux asks softly in a
surprisingly pitying voice as he presses the twin bulges against Karkat's
stomach, runs thin hands up his sides, tickling with tapered fingertips the
bumps of vestigial wiggler legs.
"F-f-fuck," Karkat stammers, overstimulated and writhing, legs reflexively
twitching as though to close around the light that holds him open. "Yes," he
moans, no longer sure whether he agrees for rivalry or desperate want as a thin
hand closes around his bulge, and suddenly his tongue is pressed again to the
roof of his mouth.
"Really," Sollux murmurs as he strokes, his hand so gentle on the shaft that
the feeling is more frustrating than pleasurable. "I didn't think you'd be into
this," he adds as he switches his attentions to himself. Both bulges secrete
pale yellow fluid from their tips as he presses and strokes them together with
practiced ease, rubbing the slick fluid copiously along the dual lengths, and
the sight makes Karkat squirm and reflexively tighten again at the thought of
taking them both. He gasps as he slides slowly upward.
"But I guess it's normal," Sollux says with a pointed smirk as he effortlessly
lifts Karkat's body up and away from the wall, bending the smaller troll toward
him and positioning himself between the glowing thighs. Karkat tenses,
suspended in the air by nothing but psionic force; the feeling of fullness that
overwhelms him as his body clenches around the light brings a groan from his
lips, muffled by his own immobile tongue. He swallows with some difficulty as
he wonders how deep the psionic force intrudes, how far inside him Sollux
already is.
"I mean it's normal that I have you trapped against the wall again," Sollux
continues quietly, looking down and reaching to work both heads against the
entrance of the spread nook. Pressing them against the opening, stroking more
slick fluid from their tips, he pauses and leans forward to look intently into
Karkat's eyes. "Time to spam the same fucking move a thousand times."
Overcome by the sensation as Sollux pushes into his strained nook - the dual
shafts are thicker together even than the psionic aura that readies him to take
them - Karkat still manages to make a garbled noise of rage as his body spasms.
Gentle hands glide over his hips as Sollux moves with strange slowness inside
him. Quickly he realizes that the psionic is holding back despite his seeming
blackrom, probably unable to bear consistent malice against him, and just as
Karkat begins to find this idea reassuring the uppermost head rubs hard against
his internal receptors.
"Hnnnnn!" he whines in a shrill, needy voice, shuddering as his hands clench
into fists against the wall. The fullness presses Sollux harder against his
receptors than anything has ever pressed, setting him off instantly, his entire
body suddenly pulsing and shaking with want. He nearly screams in frustration
as Sollux pauses to look up at him.
"Am I hurting you?" he asks nervously. The stream of profanity Karkat attempts
to shoot back at him comes out another garbled moan as he shakes his head,
straining against the psionics that hold his arms. "You...like this?" he asks,
and as Karkat feverishly nods his head the hands clutching his hips begin to
tremble. "O-oh," he whispers in awe, experimentally pushing further while
watching sweat break out on Karkat's face, "oh god, KK, that's..."
"Hnnnnn," he whines forcefully, furious, writhing in the restraints. Sollux
shivers into merciful silence, hands tightening as he speeds up. Hot darts of
pain shoot immediately up Karkat's spine and the soreness begins at once, but
the pressure and heat send his nook into throbbing spasms around the dual
bulges and this time he does scream, the noise coming out strangled and
bizarre. His legs wrap around Sollux's bony hips to force him in deeper and he
has no idea if Sollux is letting him or making him do it as desperate noises
escape his throat.
"Ohhh, you're, it's so-" Sollux pants incoherently, eyes flickering in nearly
painful brightness. Karkat lets out another muffled shriek as psionic pressure
surrounds his ignored bulge, running in waves up its length. The feeling is
perfectly timed with Sollux's thrusts and he writhes again, every panting
breath a whimper, nearly fainting for a moment. "I-is it, are you ok-"
"Unnnh," Karkat manages, overwhelmed that the normally passive Sollux is
capable of so much, and suddenly his hands are free.
===============================================================================
Karkat's instinctive impulse is to lash out at Sollux and release the tension,
to seize the psionic's throat and diminish the force that leaves his own body
overstimulated and so vulnerable; his uncertain hands clench and unclench
against the wall as heat and electricity build low in his abdomen like an
unreachable itch, promising something terrifyingly incredible with every slide
of the dual heads against his receptors, every tight wave of pressure that
glides up his bulge. His violent urge to clutch Sollux to himself at that
moment is equaled only by his pressing need to slice the psionic to bits, but
as the bicolored eyes quizzically meet his own he succumbs instead to
whimpering paralysis.
It takes him a delirious moment to realize that what holds him in place this
time has nothing to do with psionics and everything to do with pity, Sollux
flipping quadrants and taking him along. "Touch me," Sollux offers in
confirmation, tentative and merciful, and with a muffled growl Karkat seizes
his upper horns. The psionic's eyes flicker as he tilts his head down into the
touch, shuddering as Karkat thumbs the inner curves.
"Nnnngh," Karkat moans in a pleading voice as Sollux suddenly slows his thrusts
with a whine, obviously trying to delay an early climax. Some detached part of
Karkat's mind thinks that Future Karkat will despise him for that sound, so
openly needy, but in that moment - pressed floating against a wall with two
bulges stuffing his nook, waves of psionic pressure massaging his pulsing shaft
as his body trembles and burns with excitement - he cares less than ever about
appearances. Pale red saliva escapes the corner of his mouth and he lets it go,
both hands too occupied with Sollux's horns to bother wiping it away.
"S-should I...the gag, before we..." Sollux gasps, hair hanging damp in his
face. Karkat shakes his head vehemently, letting out a muffled noise, playing
along. "Really?" Sollux asks breathlessly, licking his lips, running a pale
gray tongue over long teeth. "You like..."
"Mmm," Karkat answers, eyes widening as Sollux psionically slams his hands back
against the wall again. Thin fingers tweak and roll his nubs as the bulges
slide quicker inside him, and somehow being restrained is twice as exciting now
that he knows Sollux is excited by doing it for him. For a moment he feverishly
tries to decide whether he really likes it that much or he just likes having
this effect on Sollux, this power, but as unexpected pressure rolls over his
horns a surge of heat hits him and all capacity for thought abandons him in one
desperate whine. He shudders and tightens his body around the bulges, the need
heavy and immediate in his abdomen, and he can tell by the unsteady, desperate
sound of Sollux's breath that it can't be far off for him either.
"Do it," Sollux pants, taking Karkat's bulge in a slender hand. Despite all the
psionic tricks and the two shafts working inside him, the warmth and reality of
Sollux touching him are what ultimately send Karkat over the edge with a
stifled, sobbing moan at the intensity of the pleasure that sweeps up through
him, writhing as his body spasms and bright red genetic material covers his
belly. Sollux keeps his arms pinned but works him with quick strokes and slow
thrusts before slowing and holding him steady, letting him ride it out as he
whimpers and shakes in the restraints, his eyes tightly closed.
As he begins to return to coherence, his eyes snap instantly open at the sudden
heat at the opening of his spread nook, wetness signifying the start of
Sollux's finish. At his reaction the psionic starts to pull back, already
forming a stammered apology, but Karkat wraps his legs tighter around the
narrow hips and pulls him forward. "Mmnnn!" he gasps, shivering as Sollux
floods his stuffed nook with heat that leaks out around the bulges with each
shaking, keening thrust. He reflexively clenches tight to hold the genetic
material despite the absence of pails, tilting his head back against the wall,
shocked by the amount and his own capacity to take it.
"Oh," Sollux breathes unsteadily as his body relaxes, cautiously pulling out.
"Shit." Karkat shivers again at the aching hollowness left behind, the numbness
of his tongue as the pressure fades from his mouth.
"Fuck," he agrees as he tries to ignore the sensation of fluid draining from
his body into the bucket as he pushes, the psionic energy that scrapes his own
genetic material from his skin. "Wait, where did this pail-"
"The closet," Sollux murmurs, swaying. "Your eyes were closed."
"And where the hell are you taking me?" Karkat snaps suddenly, floating across
the room.
"The recuperacoon, it has a filter." Sollux deposits him in the blue half with
a sigh of relief. "And the pail goes to the load gaper." He sends it away with
a disinterested hand motion and Karkat looks away in disgust, grimacing at the
hollow, pulsing soreness of his body as he settles into the slime. "I need to
sleep. My head hurts, KK."
"Oh no, and here I feel fantastic," Karkat retorts. "I could just hop right up
and stroll the fuck around."
"You won't have to," Sollux answers, trudging to the recuperacoon. "Since I
cleaned you up and put you in there. Because I'm not an asshole."
"Oh, really?" Karkat asks, reverting instantly to his customary defensiveness
even though his voice is softer and hoarse with exhaustion. "Your asshole
imitation's amazing then. Just flawless. It's like the role you were born to
play, right up there with 'creepy fucking weirdo.'"
"Seriously?" Sollux murmurs, climbing into the red half. "So getting tied down
and fucked with dual bulges turns you on, but I'm the creepy weirdo." He grins
suddenly, eyes half-closed. "Which would make us perfectly compatible,
actually. It's sort of a compliment."
"I didn't do anything but agree to all the weird shit you obviously wanted
because you're a fucking freak. Shit that you're way too good at, by the way. I
bet you just sit around practicing on yourself constantly, no wonder you're a
shut-in-"
"Not really. Since you tried to pull caliginous bullshit with me out of petty
spite, I figured I would show you what you were asking for until you gave in."
He smiles again, this time not sardonically. "But then you loved it. Eheheh,
KK, the sounds you made. 'Nnnnngh,'" he whines, twisting in the recuperacoon,
smile widening into a smirk as Karkat tightens his hands into fists beneath the
slime.
"You bastard," he grates out, privately despising Past Karkat already, "you
unbelievable nubslurping asshole-"
"It was incredible," Sollux interrupts, closing his eyes, still smiling.
"Fucking amazing." Momentarily disarmed by the compliment, Karkat stares at
him, hands relaxing. By the time he comes up with a devastating rejoinder and
opens his mouth to deliver it, uncertainly working up his rage again, Sollux is
already asleep.
