Work Text:
Lying on the sofa was a mistake. The crook of Dave's arm covers his eyes, taking over his sunglasses' day job. He can't help but picture Karkat lying here too. It's his usual spot. Enough so that it smells like him. It's what makes it so easy to imagine his roommate lying there, next to him. Maybe on him. Crushing him further into the cushions.
Dave crosses his legs uncomfortably. Now is not the place to be rocking a hard-on at the thought of his poor, unsuspecting friend. Dave turns to lie on his stomach and hide his arousal in case Karkat decides to walk by. It's only the middle of the day, he has no reason to be lounging around, but after the adventure they had with their friends that morning, Karkat was adamant they return home rather than exhaust themselves even further.
I couldn't sleep last night, was his primary reason. Something that was always true, but often not a point of contention. Karkat was the type to power through. Dave didn't bother pretending to be inconvenienced by the other. Something probably happened that he missed. It happened often. Usually complicated relationship stuff among his friends that ruined his mood, which Dave was expecting the other to come out and explain to him in time. For now he'd let the other ruminate in his recuperacoon while he ran yet another scenario of the other crawling on top of him, this time pressing his bulge against his ass.
Anticipation shoots down Dave's spine straight to his tailbone. He squirms again, and the friction of his quickly growing erection against the sofa below elicits a soft gasp from him, barely muffled by the throw pillow he's desperately clutching. Dave inhales deeply. Something he often does around Karkat's belongings. Usually, he would be too paranoid to be so openly aroused by the other when the other was home. The only times he pursued those deep desires was when Karkat was out, or it was late at night and he was certain the other had fallen asleep in his own room.
But, again, it's the middle of the day.
And he is lying there, in the living room, horny as fuck.
Dear Universe. Just kill me, Dave thinks to the deity that has taken shape in his head, an alien green with surprisingly innocent eyes, a wonderful juxtaposition to the scenario they've seemed to put him in.
"Fucking kill me," comes a voice from nearby.
Dave gasps again, this time from shock. He turns his head to peek at Karkat walking by him to enter the kitchen.
"Feeling alright?" Dave asks. He doesn't even bother trying to think horrendous thoughts to soften his boner like he usually does. He's hoping his luck will be on his side and Karkat will get whatever he needs from the kitchen and retreat to his recuperacoon.
"Not really. Fuckin' running hot." Karkat proceeds to down the entirety of the water from their filtration pitcher.
"Fever?"
"No. I don't know, actually. Shit feels weird."
Dave hums thoughtfully.
"Do you think you need to go to the—"
"Absolutely the fuck not. I just need to sleep… probably."
"Probably," Dave repeats. This seems to be what catches Karkat's attention.
"And what's your problem?"
"Bro, I'm not trying to start a fight."
"No, I mean—" Karkat huffs in frustration. "Are you okay? You don't usually just… lie around."
"Can a guy not rest after a 4AM hike to see the sun rise over a distant, mysterious meadow?"
"Yeah, an average fitness-level guy. Not Dave Strider."
Dave groans at the flattery, unintentional as it may be. For some reason, the thought of Karkat noticing any aspect of his body in a positive light completely melted his brain into putty. Frankly, Dave is nearly certain he'd kick his feet and twirl his hair had he not been glued to his current position.
"Maybe there's a stomach bug going around," Karkat proposes.
"We never catch the same thing," Dave counters. "Like just scientifically speaking. We've never gotten fucked by the same virus or bacteria or whatever."
"Okay, true. But I definitely have something, so what's your problem?"
Dave doesn't have an answer to that. Not one that he could share without being labelled a pervert by his roommate and kicked from their apartment.
Karkat approaches him.
No, no, no. Dave is in no position to sit up, turn around, walk away… no options existed but to stay exactly where he was until the tent in his pants collapsed like his lungs were in the process of doing at the other's sudden closeness.
"Did you twist an ankle?"
Lie and say yes.
"No."
"Did you eat something you weren't supposed to?"
Tell him you're gonna vom. Karkat would likely run to grab a trashcan, giving Dave the perfect window to escape to the bathroom, pretend to puke, and rub one out instead.
The problem was that he's done that already.
A few times.
He's certain Karkat will catch on if he keeps using that excuse.
"I'm not twelve," he says instead.
Karkat is close now. He sits on the floor, facing Dave's flushed features.
"The fuck?" he squints. "You're hot too," he says, brushing away Dave's sweaty fringe and placing a palm on his forehead.
"Thanks," Dave jokes. His voice cracks despite his attempted aloofness. He doesn't think he'll last with Karkat this close, being his sweet and attentive self.
"Do you need water?"
"Nah, man. I'm good. I'm sure it'll pass," Dave offers. Karkat remains unmoving. Dave can see the mutant blood coloring Karkat's gray cheeks a deep, rosy shade. His thick, flexible carapace shines with perspiration. Dave's thoughts wander. Karkat is once again on top of him, attentive gaze focused on Dave, sweat dripping down his neck as he rocks into Dave, slowly and oh so very deep. Dave's breathing quickens, picturing his roommate fucking him, right as he sits there, holding his gaze.
"Karkat," Dave starts. He wants to ask the other to leave him alone. Or maybe he should apologize to him for these disgusting thoughts.
"You smells so good," Dave blurts instead.
"You do too. Like more than usual."
"I usually smell good?" Dave smiles. Karkat rapidly blinks away a drop of sweat that had fallen onto his long lashes.
"You usually smell like you. But right now you smell like…" Karkat tilts his head, thinking, eyes still glued to Dave's. "The same, I guess. But it's stronger. Not bad though. Your smell is probably the least offensive ones among my friends."
You're so fucking cute, dude. Dave wants to say, utterly enraptured by Karkat's mannerisms when in his state of thoughtfulness. "I need you in me."
Karkat blinks again. Dave didn't see any sweat fall this time.
"What?" Karkat asks.
"What?" Dave senses a shift in the other. And yet, despite the dread in realizing that he had just said that last bit out loud, the churning of his stomach did little to discourage his arousal.
"I heard what you said, Strider. I've become fluent in your mumbling."
"Sorry," Dave whispers. Terror takes hold of him. He clutches his pillow a little tighter, utterly appalled that getting caught merely brought more heat to his lower stomach. "Jesus, Karkat. Sorry," he whimpers.
"You want me in you?" Karkat repeats, a hand on the small of Dave's back. There is no saving him from the way his body reacts to the warm touch. Dave buries his face in the pillow to muffle his moans as he comes in his pants.
"Sorry," he gasps, turning his face for air. He barely gets to swallow it down before lips press hungrily to his. Karkat is standing from the floor, clawed hands digging into Dave's arms and flipping him onto his back with ease. Dave fights to breathe and kiss Karkat simultaneously. His brain is completely deprived of oxygen. All the blood in his head rushes between his legs, arousal building yet again. He's never recovered this fast before. Karkat doesn't seem to notice the power he wields.
Dave is a moaning mess when Karkat crawls on top of him. No amount of daydreams (and wet dreams) could have prepared him for how incredible it felt having such a heavy troll crush him into the sofa. Dave opens his legs so Karkat can slot between him comfortably, and he begs with his body for more. Dave humps the air, seeking friction, only to be met with steady hands holding his hips still. Never in his life did he expect to be so needy. And so noisy. Dave whines. He says Karkat's name with such shameless desire it's a wonder he ever bothered trying to act cool in front of anyone. Karkat was bringing out the real Dave with every intentional touch, every removal of clothing, every kiss and every affectionate whisper of how much he loves him.
Dave comes again at that word. His entire body shakes as ropes of spunk line his exposed stomach.
"You're evil," Dave manages after taking a minute to catch his breath.
"I haven't even done anything yet," Karkat croaks. Dave encourages him to do just that. He beckons the other close, kissing those jagged teeth, head still dizzied with lust.
"Take your time," Dave instructs in a low tone. "I think— I think I can do this all day."
"Same," Karkat hisses. He kisses Dave's cheek, and finally, finally guides his bulge between Dave's legs. He moves slowly in Dave. Despite the tapered end of his appendage slick with genetic material, Karkat takes his time with Dave. He opens him with little resistance, but still he doesn't rush. Dave is a mess. This is all he's ever wanted. His insides are on fire. Every thrust, intentional and profound, burns Dave to his core. He can no longer tell where Karkat starts and he stops. Dave has his third orgasm, tears streaming down the sides of his face as Karkat continues to fuck him.
Only then does he finally speed up. Dave cries the other's name, rocked with such intensity he's certain his back will be reddened from fabric burn. He doesn't care. Karkat ruins him. He ruins the couch too. And though he reaches his climax, it seems there's no stopping for him either.
Karkat fucks Dave until the sun sets. Hungry and dehydrated, the only thing that seems to bring light to their basic needs was the passing of time.
It's only then, they learn, when the weird fog of arousal has finally lifted, that they were definitely under the influence of more than just mutual love and lust. A worried text from Jade in the group chat confirms their suspicions that night, flagging to all who participated in the hike that there was plant pollen of a endangered species in the area that might have caused a "reaction". Eloquently put. Unlike a viral or bacterial infection, the molecules of said-pollen fit into the same smell and taste receptors that humans and trolls seemed to genetically have in common. A complete luck of the draw, where natural selection evolved these two completely different species similarly this one, very specific way.
Dave's thighs shake when he stands. Karkat holds him up with a tight embrace.
"I didn't even notice," Dave admits. "It's not the first time you've gotten me riled up," he smiles. Karkat kisses his nose. Dave melts into his embrace, utterly weak to those tender expressions of affection. The stuff of dreams, maybe even more so than the dirty stuff he always imagined doing with his roommate. Gentle kisses were somehow more unrealistic to him than getting fucked sideways. Who knew he'd be getting both.
"Same, honestly," Karkat says, pulling Dave out of his thoughts. "Just felt a little more brave, if anything."
Dave huffs. Karkat kisses him again, this time a caste peck on the lips.
"We should find that flower," Karkat says after a beat of silence. "S'kinda nice, not being able to stop."
"Tell me about it," Dave sighs wistfully. "I counted 15 orgasms. The barrel was completely empty after the fourth one. I've never shot blanks before. I'm pretty sure I should be dead right now."
"Stop talking before I make it 16."
Dave raises a brow. "The pollen's worn off dude, there's no way you still have it in you."
"Did you miss the part where I said I didn't even notice it in the first place?" Dave inhales sharply at the sensation of Karkat's bulge twitching between them. Oh.
"Oh."
"Let's shower," Karkat says with his usual, commanding demeanor. "We'll make less of a mess in there."
"Oh fuck," Dave exclaims when Karkat swoops him up into a bridal carry. He doesn't think his poor, overstimulated prostate can take it anymore, not without the plant's influence, but those strong arms stir something inside him, encouraging him to give it a shot.
Dave has his sixteenth orgasm that day.
