Summary
     Karkat, Sollux, the red quadrant, and a bucket. 100% troll porn.
     Nothing human here. If you want plot you're in the wrong place.
Notes
     For Robotsquid.
Karkat tossed his bag unceremoniously onto the coffee table, plopped his ass on
the couch, and started flicking through the annoying Earth channels. He hated
Earth. He hated Earthlings. And most of all, he hated John Egbert.
Passionately.
He was also exhausted. John was exhausting. Earth was exhausting. Humans were
exhausting. Granted, Earth was better than being stuck on a meteor inside a
broken game. It was also better than being dead, and it was better than the
entire troll race going extinct.
But on some days, all Karkat wanted to do was come home and be a proper troll.
Read books in Alternian, surf the Alternian part of the internet, spend time
with his Alternian matesprit...
He felt nice, sharp claws rubbing his shoulders and groaned.
“Well don't you look jutht like thomething the meowbeast dragged home.”
Sollux's voice purred in his ear.
“Shut up, you don't know how it feels dealing with a human kismesiship...” his
voice trailed off as he leaned into Sollux's massage, his troll claws digging
into his flesh hard, working the knots away with ease. Human skin was as
fragile as paper; troll claws went through it by mistake, even. Karkat had
learned the hard way that he had to be careful with John. He had to treat him
like a porcelain doll, almost; which was kind of strange when you were in the
throes of black emotions.
But his matesprit was a proper troll. 100% from Alternia, grey skin, normal
blood (not that Karkat could complain about John's blood color), and a gorgeous
double set of horns. He also had nice, sharp claws that dug deep into Karkat's
muscles, not breaking his tough skin, but working out all the kinks and stress
of the day, just right.
“Uhhnnnn...” Karkat purred.
“I'll take that two mean you've mithed me.” Sollux purred in his ear, as he
leaned forward to give it a nip.
“Sol, you're plenty sexy, but I'm too exhausted to fill any buckets today...”
Sollux didn't seem to hear him as he lowered his lips to plant kisses down
Karkat's neck. Karkat moaned and let his head fall back to rest on the top of
the couch. He inhaled and his nose was filled with the sweet pheromones of a
very turned on mustard-blood.
“Seriously, I'm tired...”
“You will be.” Sollux whispered, and he lowered his lips to kiss Karkat's
throat, grazing his teeth over his skin, making Karkat shudder at their proper
sharpness.
After spending so much time surrounded by humans, it felt incredible to be
touched by another troll body. Karkat found his arms lifting up against his
will to wrap around Sollux's neck. He pulled him down, yanking him over the top
of the couch, until his matesprit fell on top of him. Karkat leaned back and
Sollux continued his assault of slow, wet kissing nips down Karkat's throat.
Karkat purred. Not a meowbeast kind of purr, and not the weird purry thing John
did, but a true, I'm-in-deep-pity-with-you, deep throat rumbling sound. Sollux
answered him back almost immediately. He lifted his face and Karkat found
himself staring up into two different colored eyes, his glasses nowhere to be
found.
“I pity you.” Sollux said, in perfect Alternian.
“I pity you more, fuckface.” Karkat cooed back; his eyelids half closed. Sollux
rolled his eyes and went back to kissing Kk's throat. Karkat slid his palms up
Sollux's back, feeling his coolness in such beautiful contrast to the hot skin
of humans. He slid his hands up to Sollux's hair and clasped it, not afraid of
hurting him. He was a troll. He was tough.
Karkat yanked Sollux's face up to his by his hair and brought their lips
together. Sollux eagerly opened his mouth and let Karkat's tongue inside of
him. He groaned as Kk teased the roof of his mouth with his tongue, a sensation
that seemed to not have an effect on humans in the same way. Sollux slid his
lips hungrily over Kk's, his clearish mustard drool bringing delicious flavor
to Karkat's senses.
Karkat gave Sollux a mischievous look, but before he could ask what he was
going to do, his hands slid up the smaller troll's hair and his fingers traced
around the base of his back left horn.
Sollux groaned as his breath came faster. Karkat moved his other hand as well
and began to pet two of Sollux's horns around the base, teasing the sensitive
flesh. Sollux melted into him, his arms no longer willing to hold him up, as
his chest sank to rest on top of Karkat's. He could feel his heart beating
against his chest, and in a moment, felt Sollux's bone bulge start to harden
under his black jeans.
“Kk...” Sollux managed, but no more intelligible words followed. Karkat smirked
and wrapped one arm around Sollux's waist. Showing off his superior strength,
Karkat slid out from under Sollux and tossed him down on the couch, face up. He
then went back to petting Sollux's scalp around his horns, his partner able to
do little more than give him a desperate, blissful look.
Karkat felt Sollux's bone bulge push up against him, and he ground down onto it
with his own. It was a maneuver he'd learned from John, but it drove Sollux
just as wild.
“You are such a fucking tease...” Sollux said, panting underneath him.
“You haven't seen anything yet.” Karkat said, his blood rushing to his cheeks,
making them burn. He released Sollux's horns, leaving the smaller troll panting
heavily under him as he sat up, straddling Sollux's hips. He slowly slid his
fingers down his lover's sides, slipping his claws under the bottom of his
shirt. He gently caressed Sollux's skin with his claws as he pulled the shirt
up over his head, making his partner shiver.
Karkat removed his own shirt next, without any sort of ceremony, and Sollux's
hands immediately went to touch his bare skin.
Karkat shuddered at the touch of his cool, dry skin. It was so trollish. It
felt so right.
“Kk.” Sollux cooed, his eyelids half closed, his cheeks and ears flushed
bright, mustard yellow.
“What?”
“Mate with me.”
Karkat stopped moving and looked down at Sollux with surprise. Filling buckets
was one thing. Mating was another. Filling buckets was akin to jerking off
together; you enjoyed each other's company, excreted genetic fluid, and then
disposed of it however, sort of like when humans wore condoms to not get babies
growing inside of them.
Mating was something else entirely. You mixed your genetic fluids together,
internally, before releasing it into a bucket to give to the drones. It was
live, it was complete. It was capable of making new baby trolls. Creating it
was extremely intimate. And Karkat and Sollux had never done it before.
“Today?” Karkat asked, suddenly nervous. His skin started to glisten from
nervous sweat. He blushed, embarrassed.
“Yeth. I pity you, with all my heart.” Sollux said. “You thaid you wanted to,
when we talked about it.”
He had. They'd talked about it, several times, since Kanaya had managed to
finally hatch a new mother grub. It wasn't grown yet, but that didn't matter.
Troll genetic slurry could be stored. Whatever they made together, Kanaya would
save it until the mother grub was mature. But that was sweeps away. Karkat had
thought they'd do this, oh, three sweeps from now, or something. Of course he
wanted to save the troll race and all that. But right now?
He looked down at Sollux's adorable face and felt how deeply he pitied him. He
was so frail. So small. So prone to bouts of emotional irrationality. So
helpless without Karkat. Just as Karkat was helpless to keep himself in check
without Sollux always there to tell him to shut the fuck up. They belonged
together. They both knew it. It was right.
Karkat swallowed the huge lump in his throat.
“Oh...okay.” he said. He saw a nervous smile come to Sollux's lips.
“Awethome.” he said softly.
Karkat's fingers shook with nerves as he lowered them to Sollux's zipper.
They'd filled buckets together plenty of times; he'd seen Sollux naked
countless more times, coming in and out of the shower, sleeping in his
recooperacoon, just changing in front of each other.
But this time felt different. Now everything was so impossibly serious.
Karkat pulled Sollux's pants and boxers down together, not wanting to draw this
part out any longer. His bulge was already halfway out of him, yellow precum
slicking the tip. Karkat got to his mismatched shoes and yanked them off
quickly, until he was standing beside the couch looking down at a naked,
yellow-flushed scrawny, adorable Sollux.
Karkat yanked open the door under the coffee table where they kept a stash of
buckets and drain-pans and pulled one of each out, the rest of the stack
falling over with an obnoxious clatter. Karkat quickly slammed the door shut
and set the bucket down beside the couch, ignoring Sollux's condescending
giggles.
He glared at Sollux with the drain-pan clutched between his claws. Sollux
obediently lifted his ass so Karkat could set the metal pan under him, ready to
catch whatever they produced and funnel it into the bucket beside the couch.
He hurriedly yanked his own pants down, stepping out of his shoes so awkwardly
he almost fell over.
“First time dressing yourthelf?”
“Shut up, assface.”
“Make me.”
Karkat was back on top of him in seconds, his lips hungrily kissing Sollux's,
his delicious mustard aroma wafting up to drown all of Karkat's senses.
Sollux's arms reached up to wrap around Karkat, his palms resting on his back,
his claws tracing light, tingling lines down his skin until he grabbed his ass.
Sollux gave it a squeeze and Karkat glared at him. Sollux bit his lower lip in
a very human-like fashion, but his teeth were dazzlingly yellow and beautifully
sharp. Karkat couldn't keep himself from kissing him some more, tasting him,
drinking him in.
Sollux lifted his hips, his bulge sliding fully out from between his legs now
to wrap around Karkat's, stroking it, easing it out further.
Karkat groaned, heat rushing between his legs as his pulse pounded in his ears.
He felt his bulge wriggling out of him, eager to entwine itself with Sollux's,
both of them becoming slick with precum as they shivered with an overload of
sensation. It wasn't long before Karkat's bulge was fully out, pulsing with
eagerness.
“Which way did you want to...”
“Come inthide me.” Sollux whispered. Karkat shuddered. He'd known they would do
it this way, of course. Sollux was the smaller troll. Both of their instincts
would want him to be the one who was invaded. Karkat's cheeks flushed bright
red. He'd never even watched porn of such a thing. This was beyond kinky. It
was natural, sure, but... you just never talked about this kind of thing
outside from health lessons.
Karkat's mind had brief flashes of recollection from those lessons. Of cartoon
pictures, showing the different sexual organs of trolls. Of textbooks
explaining that male and female trolls had different secondary sex organs for
pleasure, but when it came to mating they were identical. Every troll had both
external and internal organs.
Karkat had never seen either, not even his own. It was just so...intimate.
His cheeks flamed red as Sollux's fingers ticked on the inside of his thigh,
passing beneath his bulge, beneath his shame globes. They were bulging now,
building up the genetic material he was going to release, not into a bucket,
but into Sollux. He felt fingers stroke against a body part he'd only been
brave enough to experiment with a few times by himself. No other troll had ever
touched it. John didn't even know it was there...and he never would, Karkat
swore.
Sollux's fingers teased their way up between Karkat's legs, until they brushed
against a thin, slender tendril that was very verysensitive. Karkat shook and
gave an undignified whimper.
“How's this feel?” Sollux whispered. Karkat couldn't look up at his face. His
cheeks burned. He shook.
“Is it too much, should I...?”
“IF YOU STOP I WILL SNAP YOUR FINGERS OFF!”
He heard Sollux chuckle.
“Glad to know you're still in there.” he said. Karkat tried to growl at him,
but it only came out as a soft purr. Pleasure was spreading up into his abdomen
in pulses, his nerves growing more sensitive in wave after wave, until he was
desperate for more touch, until Sollux's fingers became a torturous tease that
was not enough.
Karkat growled and yanked Sollux's hand away. Driven by burning lust, he shoved
Sollux's legs apart wide, making him gasp and whimper.
“Kk...” he said, suddenly sounding very nervous. Karkat's eyes flew up to his
face.
“Last chance to change your mind.” he said, pleasure burning through him,
driving him to want to move forward.
Sollux nodded.
“I'm ready.” he said.
Karkat slid forward, their bulges brushing together. Sollux gasped, but the
sensation from that was almost nothing to Karkat now. He spread his own legs as
Sollux bent his knees, letting him closer, until the exposed tendril from
Karkat's mating bulge brushed against the soft, sensitive place between
Sollux's legs, under his own bulge.
Sollux gasped and Karkat shook. He groaned and pushed forward more, desperate
for more touch, more, more, more. He heard Sollux's voice squeal and felt him
shudder. Karkat felt warmth. He felt heat. He was driven into it, and it took
him a good ten seconds before he dimly became aware that his mating bulge was
emerging, sliding into Sollux, the thin tendril that could become both a
protrusion or a tunnel; and Karkat's was forcing it's way inside of Sollux's,
pushing him inwards, farther and farther.
The preliminary tendril was followed by more; thin wisps of delicate, sensitive
nerves branching from the center, each protrusion pressing deeper and deeper
into Sollux, like a tree spreading more roots, cementing itself inside of him.
Karkat could barely think. His heart hammered so loudly in his ears he was deaf
to the world; all he could feel was Sollux, all he could see was Sollux. His
face was contorted in a strange expression caught between uncertainty and
pleasure, nervousness and desire. Karkat felt his matesprit shaking beneath
him. He slowed his drive inward.
Sollux's eyes opened to look at him. He was as beyond words as Karkat was, but
Kk knew he could see the concern on his face. He was asking him if he was
alright. If he wanted to continue.
Sollux's body gave him his reply. He felt his long tendrils, buried deep inside
Sollux, being pulled. Sollux's own mating bulge was stroking him, pulling him
in deeper, welcoming him. Karkat's eyes grew wide as he spread his tendrils
further along the tunnels Sollux made for him. He felt his lover stroke him
along every edge, every side, of his most sensitive organ. Both of their
breaths rushed in and out of their lips incredibly fast. Sollux seemed to have
forgotten about all the rest of his body. He was collapsed onto his back, his
right arm dangling forgotten over the edge of the couch, his left arm smashed
into the crack between the cushions.
After a long, drawn-out eternal moment, Karkat felt himself fully extended.
Sollux surrounded him on every side, burning pleasure driving along every nerve
he owned as Sollux stroked him internally. Karkat looked at his face, language
long gone. He lowered his lips and they kissed, and kissed, and kissed, their
lips sliding together, their tongues entwining in an imitation of what was
happening inside of them. To an outsider, their position looked no more
remarkable than if they were simply lying together, and yet they were bound
together so intricately that it would take the same half hour for them to come
apart as it had taken them to so fully come together.
Karkat rested on top of Sollux as he lay drowning in pleasured bliss. Neither
of them appeared to move, because every bit of sensation was happening inside
of Sollux. Their breaths came faster and faster, their skin growing sweatier
until drops fell from Karkat's forehead to land on Sollux's chest, where he
rested his face. Now and then, when he remembered that he had a body, he'd
plant a kiss on Sollux's beautiful gray skin. Eventually, he forgot about skin.
The heat suddenly drove up in thick, heavy waves. Karkat shook heavily, pushing
himself up with his arms as the vibrations inside Sollux drove him mad. He
growled and purred and cooed all at once, gazing lovingly down into Sollux's
face as he felt a tingling sensation spread from the tips of his organ all the
way to it's base between his legs. Sollux's head snapped up, his chin pointing
toward the ceiling, and Karkat felt wetness ooze out from every place inside of
him that Karkat touched. Karkat groaned, the sensation overwhelming him, and
then felt his own cum start to flow from every branch that had spread inside
his lover. Their cum mixed together, rushing quickly along the pathways where
they connected to pour out from Sollux.
It flowed into the drain-pan and down into the bucket, the sensual sound of
liquid hitting metal that could make any troll blush. Karkat shook with burning
pleasure as he felt Sollux's arms lift to wrap around him. They held each other
tightly as they came, their breaths erratic and their hearts hammering with
fire.
Sollux's claws dug into his back deeply, pricking droplets of red as he shook.
Karkat held him back just as tightly, until the muscles in his arms burned as
brightly as the heat in his abdomen.
Sollux stopped shaking beneath him. Karkat's breathing slowed. Sollux's arms
let go and flopped to the couch, exhausted. Karkat's heart beat more normally,
and he felt his mating bulge begin to retreat.
It was sticky and awkward and a little uncomfortable. He saw Sollux wince a bit
as Karkat retracted, pulling more sticky orange slurry out with him as he did.
Each branch shrank back inside of Karkat one at a time; he wanted to yank his
whole organ back in at once, but he forced himself to be gentle for his lover.
When they finally came apart, and all organs were back inside the troll they
belonged, both of them rose up to yank the drain pain off the couch.
Karkat collapsed beside Sollux and wrapped his arms tightly around him.
“Wow.” Sollux whispered.
“I actually agree with you.” Karkat replied. He reached up his fingers to
stroke them lovingly through Sollux's hair, being careful to avoid the overly-
sensitive parts now.
“It's nothing like you hear about.” Sollux said. “Nothing.”
“Yeah.” Karkat said softly. For once, he was at a loss for words. There weren't
any. There really weren't.
“Karkat, I love you.” Sollux said. “In the most red, flushed, delicious way
possible.”
“I love you too.” Karkat said, too tired to think of an insult. Sollux turned
to say something else to him, but he was already deep asleep, having never felt
so satisfied or so right in his life.
