All in all, it’s been a day of perfect opportunities. For the first time in months your three roommates all had plans, and in a perfect line up of circumstances, both you and Karkat’s schedules were free of obligations. 

For once, there was no friend drama to deal with; no parties demanding your obligatory attendance, and no deadlines to worry about - at least not ones you aren’t willing to ignore for a night or two. And you, for one, planned on taking full advantage of this miracle of miracles.

It’s been an evening full of a romantic home-cooked meal (frozen chicken totally counts), equally romantic movies and inevitably dabbing away Karkat’s tears after every cheesy line of dialogue. Personally, you’d rate it as a solid 10/10 hats so far. The only thing that could make this night any better is a high class sloppy makeout sesh, which luckily for you, seems to be on Karkat’s mind as well.

Eventually those decreasingly chaste kisses and further-wandering hands wound up here, with you lying horizontal on your back with a lapful of needy troll gnawing frantically at your  neck.

Fuck the hat system. No amount of hats could rate how excited you are to be here; how much your heart is thumping with every second of increased ferocity.

You’ve got Karkat purring in your ear like a cat on its first taste of nip, arching up into your fingers as you run them up and down his back. Both your shirts got tossed to the floor a while ago, giving you unparallelled access to the VIP lounge of bare grey skin you’ve had the pleasure of getting intimately familiar with over the last few months.

It isn’t until you chance slipping those hands a little lower to cop a feel of his ass that Karkat finally breaks away, voice raspy and guttural.

“Dave.”

Ohhh yeah, shit, hearing your name on those kiss-swollen lips is goddamn music to your ears. Music to your dick too, considering how it jumps in the increasingly tight confines of your skinny jeans, trapped up somewhere near Karkat’s hipbone. It’s enough to make a guy go stupid.

Not stupid enough, however, to be reminded that this is usually where such excursions end.

The apology is already in the back of your mind as your hands still at the arch of his back, trying your best to calm the disappointed ache in your crotch. You forsee a cold shower very close on the horizon. “Sorry babe,” you start. “Do you wanna-?”

Karkat pulls himself up from his resting spot, giving you a fantastic look at his rumpled hair and black-blown pupils, which immediately avert themselves to the mark he’s spent the last few minutes lovingly crafting on your neck. It aches in the best kind of way.

“No,” he starts. “No, I’m okay, I just…”

“Need a minute?” You need to stop interrupting, you know, but its a bad habit of yours to fill in the gaps in conversation with questions or assumptions. Usually your intuition is right.

Usually.

Those sharp ass teeth worry briefly at his lower lip, the red flush spotted across his cheeks darkening ever so slightly in the candlelight.

“Actually.”

He pauses. Clears his throat, and you force your expression to remain neutral and your hands stillhis hands to stay still, and though its much harder, forces your tongue to do the same.

“I was wondering if. Maybe I could…”

One of his hands slips down to rest on your stomach, just above the button of your jeans.

Oh?

… Oh.

You have to physically fight with your face to not make some kind of idiotic expression, opting to prop yourself on your elbows as best you can. You have no hope of hiding how your boner jumps, and given how Karkat’s palm comes down to brush it curiously, you’re pretty sure he feels it too.

Embarrassing. But fuck it, you can endure a bit of embarrassment if it means a bit of relief.

“Yeah!”

Too eager. Haha, oops. Tone it down a bit Strider, you can be cool about this.

“Yeah,” you try again, more neutral this time. “Whatever you’ve got in mind babe, I’m up for it - I mean, maybe we could talk about it while we do it, make sure, all of that shit, make sure we’re both comfortable-”

“Fine with me,” Karkat interrupts this time, sharply. You know his levels of sharpness well enough to clock that he’s embarrassed. His hand comes down a bit further to rub along your boner, and even this small amount of pressure is enough to make you gasp. “How is… this?”

“Good.” You try (and fail) to keep your voice smooth. You’re way too turned on already, heat and anticipation pooling in your dick rapidly enough to suggest you won’t be able to endure a whole lot of teasing, no matter how long you want this to last in theory. He presses a little harder, and you grunt.

“Lil’ much babe - some pressure is nice, but it’s better if you- mmmh-”

He switches back to rubbing the same way as before, curling his hand delicately around your boner to stroke down it in a line. You relax into the feeling, thighs twitching slightly as he peers at you with curious eyes.

“It’s different,” he grumbles. “Does it not move like a bulge?”

“Uh. I guess not?”

You don’t really know what a bulge moves like. Maybe you should have come into this better prepared. But between growing up with your bro, your lack of privacy at college and your mutual embarrassment when it came to bringing up your respective anatomy, you don’t really know a whole lot about what Karkat is packing down there. The best you’ve managed is a single troll-on-troll video, and you felt so weirdly invasive about it that you turned it off after the first five minutes.

(Whether or not it succeeded at turning you on is a secret you’ll take to your grave. Or at the very least, until you and Karkat have a bit of liquid courage under your belts).

“You guess? Or you know? ” he probes brow furrowing in a way that feels both judgemental and very sexy.

“I mean, it, like. Twitches and stuff?”

“I can feel that.” 

He begins to reach for the button at the front, and you dick gives a very helpful demonstration. You can’t help but hold your breath as he pops it open and eases down the zip. There’s already a slight wet spot in your smart black briefs and he thumbs at it curiously, toying with you.

“You also produce genetic material?”

“Genetic- you mean cum?”

“Probably? Apologies for missing out on my fucking human anatomy health class, okay? I didn’t think I’d be in this position tonight.”

You reach out to brush your fingers down his arm and do your best to look reassuringly sexy.

“It’s - fine. We can figure it out together, right? Have a little show and tell?”

You waggle your eyebrows and he furrows his, but his scoff has a hint of amusement to it, so you think you nailed your intention.

“Then - maybe we should start with the show. And maybe a tell, if you can be serious about it.”

“Hell yeah, babe, serious as a heart attack. One show comin’ right up.”

You stick your thumbs into the line of your jeans and awkwardly wriggle them off. Karkat dutifully shifts out of the way and laughs at your attempts to get free. Curse these stupid fucking jeans; hands down the worst decision of thenight, even if they do make your ass look phenomenal.

You’re left in your briefs and nothing else, and Karkat is still looking woefully overdressed.

“Maybe you should join me?” you suggest, reaching out to where he’s curled himself up on the other side of the bed. Your hand clumsily finds one of his thighs, which squeeze together instinctively.

“Maybe. I mean - yeah. That seems fair.”

He too begins working on his jeans, rolling over onto his back to get them down his legs. They come off a lot easier than yours, tossed to the floor along with the rest of your clothes, and you’re treated to your first proper look at his unclothed legs. Man. Those thighs. You want to bury your face in there and see what you can find.

Hm. Now there’s a thought. And really, why shouldn’t you? What’s stopping you, so long as he’s up for it?

With this idea in mind, you roll over to face him and pull him back into a kiss. The soft chirp of surprise is weirdly erotic, but not as erotic as the way his hands start pawing at your back, mindful of the claws.

You let the mood build back up again, stroking your hands over his back, then his sides, toying with the grubscars until he moans into your mouth. This time, when you let one of your hands wander down to cup his ass, he leans into it and pinches your lip between his teeth, and that’s a go ahead if you’ve ever seen one. 

His hips arch forward at the same time as yours, grinding against you with increasing fervour. A hand finds your ass too, claws snagging the fabric of your underwear as you gasp into each other’s mouths.

You’re trying to scope out his situation. It’s not the first time in your sloppy makeout sessions that you’ve felt something stirring against your dick, but it’s the first time it’s been so tantalisingly close. From what you can gather, his bulge is a lot more active than your dick; it feels almost like a second hand down there, thrashing wildly in an attempt to get closer to you.

It feels about time to let the caged beast free. Poor dude is wiggling up a storm down there, and you’re pretty sure you can handle whatever he has to give you.

You roll Karkat onto his back, kissing a line down his neck that culminates in a bite mirroring yours. The trill he makes is way too fucking hot, and you let out a low moan of your own as you trail your mouth further down. A hand tangles in your hair as you kiss your way down his chest, licking a stripe down his abdomen where a human would typically have a belly button. 

He doesn’t stop you but you look up at him anyway, just to check in. He’s staring down at you, pupils blown so wide you can barely see the ring of yellow around them. You maintain eye contact as you hook your fingers into his underwear. This close, you can feel how much his bulge is wriggling; how hot and slick he feels. It turns you on so much you can barely think.

“Can I?”

The hand not on your hair is half covering his face, barely hiding how flushed his face has gotten. You wait, even though the anticipation is killing you.

“... Yeah.” He shifts, lifting his hips up to help. “Yes. Please, fuck.”

You eagerly oblige, bringing your mouth down to kiss his lower stomach as you curl your hands and pull.

Something hot and slimy whips out like a rocket, slapping you straight across the face. You choke in surprise and Karkat slaps his face in embarrassment, the hand in your hair rudely shoving you backwards.

“Fuck! Sorry, shit, I didn’t mean to. It does that on its own.”

You stare. Worming its way up into the air is a red, dripping tentacle.

Well. Shit. Now you know why all your friends joked about hentai dicks.

You wipe the gunk off your face and give him a reassuring thumbs up. He doesn’t seem to find it as amusing as you do.

“It’s fine babe, just surprised me. Lil’ guy is just eager to get to business.”

Not that it’s actually little by any stretch of the imagination. Length wise, he’s got some growth on you, but it’s definitely different to what you’re packing. At the tip it’s about as thin as your pinky finger, but nearer the bottom it’s about as thick as your wrist, with the very edge of it seeming to disappear somewhere into him.

You keep staring, probably for longer than is considered polite. His bulge seems to have a life of its own, writhing in the open air and dripping up a storm all over your sheets. Karkat makes another embarrassed noise, and you take that as your cue to get to it already.

“Alright. Lets see if I can just…”

You thread your hand around him and his bulge latches on immediately, threading its way between your fingers and curling around your palm. It has a surprising amount of dexterity, pulling your hand closer with no small amount of force. You let it guide you, because it probably has more of an idea of what to do here than you do.

Karkat makes a much more reassuring noise as you bring your hand down, stroking your way over his bulge like you would your own dick. It’s a bit difficult, because it’s squirming all over the place and slippery as fuck. You give it an experimental squeeze, and he grunts.

“Careful! It’s sensitive.”

“Sorry.”

You loosen your grip, petting at him with a gentler kind of curiosity. It curls around your hand and seems to push you lower, towards the connection point between bulge and skin. There’s some kind of… hole? Maybe? You’re not sure, but you figure it might be a step too far to go spelunking into places you’re not a hundred percent sure you’re welcome.

Besides, you’re here on a mission. So like the good little explorer you are, you brace your hand around the bottom of his bulge, open your mouth and guide the tip of his bulge right in there.

The sound Karkat makes is delicious; a throaty, eager yell that distracts you from how his bulge immediately plunges its way down your throat. You almost choke on it - key word being almost, because you’re a goddamn professional and he’s leaking up so much slick that it glides down easy. You’re just a bit taken aback by this situation, which you shouldn’t really be considering your observations.

New observation: having a throat full of troll dick is also really fucking hot.

You adapt. Your cheeks hollow, throat relaxing as you coax the very bottom with your tongue, and his bulge undulates in a way that seems promising. It’s so much more pliant than a human dick, adapting to the tight confines without fully cutting off your airflow.

You let Karkat’s noises guide you, and there’s plenty of those to go off. Unsurprisingly, he’s just as noisy with your head between your legs as he is anywhere else, and the enthusiasm is really getting to you. Each new chirp and yell and trill is enough to leave you aching, grinding your hips against the end of the bed for a bit of relief.

You slip into a rhythm of sucking and swallowing, the flow of slick seemingly never ending. You feel like you’ve drank a goddamn river of the stuff by the time Karkat slaps frantically at your head, and you pull up with a loud, wet smack. His bulge reaches for you the second you break free, which is also, surprise surprise, a huge fucking turn on.

You swallow your last mouthful and pant, voice thick and syrupy as you finally get your words out.

“You okay? Do you wanna-?”

You’re cut off as he lunges at you, kissing his own cum from your mouth like a man possessed. It takes everything you have not to cream in your undies then and there, but you manage it somehow.

“I don’t- I’m not ready to spill yet, holy shit, Dave,” he pants, then immediately pulls you in for another kiss, dragging you up on top of him. His bulge reaches for your confined dick, snaking its way around the band of your underwear like it’s desperate to wrap around you. Shit, yeah that would probably feel really good.

“Okay,” you groan as his mouth moves back to your neck, resisting the urge to get your hand on his bulge again. You really want to make him cum, but if he wants to cool off, you’re obliged to listen. You’re certainly not gonna complain about keeping this train going. “Then what do you - want to do?”

“I want to touch you,” he purrs, reaching for your crotch. “Please.”

You nod frantically as he begins pawing at your underwear, moving your hands down to help him ease out your dick. He also takes a moment to stare, brow furrowed in curiosity as your boner sits there out in the open.

Okay. Yeah, you understand why he was embarrassed about you looking before.

“Like what you see?”

He looks up at you, mouth twitching.

“It’s so… Different.”

This time it’s his turn to paw at you, pressing a hand curiously around your boner. You hiss quietly through your teeth, heart jumping at the thought of those claws near anything sensitive. To his credit, he’s very gentle about it.

“It’s so firm. How do you deal with it being like this all the time? Doesn’t it get annoying?”

“It’s not - all the time. Just when I get turned on,” you explain, trying not to let the sudden embarrassment overtake you. It helps that he’s stroking you experimentally, gliding his hand over you the same way you started stroking his bulge. “What about you, does it get annoying having yours out like that?”

“I don’t. It goes in when I’m not. You know.”

You do know. Well, that explains the entrance you found underneath it. Maybe it just sort of folded itself back in there?

You don’t dwell on it for long. Karkat’s scootching closer, petting down at your dick in his hand like its a puzzle he’s trying to solve.

“I don’t think I can. Uh. Return the favour. With my fangs I’m not sure that’s the best combination.

You both cringe.

“Yeah I’d rather not babe. We can try somethin’ else if you want, but teeth and dick do not go together.”

“Yeah I figured,” he scoffs, then shuffles forward. “How about this?”

He must’ve had the same idea earlier as you, and as soon as you pick up what he’s putting down your hips move to do the same. His bulge twists around your dick, and the first stroke is enough to make you see stars.

“Oh fuck,” you both groan at the same time,.

“That feels-”

“Really good,” you agree, rutting into the grip with a low moan.

From there, you let your bodies do the talking. It’s a whole new world of sensation. It’s so different to anything you’ve ever felt before, and so incredible it makes your toes curl.

You fall into a whole new kind of rhythm. The slippery heat is delicious and you absolutely can’t get enough of it, the two of you gasping as you rock and grind against each other with increasing eagerness. Your mouths find each other again, kissing and licking and occasionally biting when a twist of your hips feels particularly good. It ends up with you on top of him, grinding down into the grip of his bulge and relishing every loud noise you get him to make.

You wonder what it would feel like to fuck him for real. It’s easy to picture with the two of you like this; legs tangled and hips thrusting in an imitation of the act itself. If this is how good it feels with his bulge around your dick, how good would that be?

You try to think of something romantic to pitch the idea; something that’ll fully explain how how much you love him; love making him feel this way; how you want to do everything in your power to make him feel just as incredible as you do right now. 

“Karkat,” you gasp against his hair, and he moans out a curious noise against your neck.

He wrenches his head back enough to meet your eye, never halting his hips. How can one guy be this beautiful? You want to eat him up. You want to blow his mind.

“Can I fuck you?”

His pupils dilate, that rattled purring lowering down just enough for him to get his words out.

“ Now?!”

“Maybe?”

“You’re - pretty big. We might need to…”

“We can prep,” you promise, kissing his forehead. “Get’cha nice and wet, ‘til you’re desperate. Really take our time with it. I think it’d be hot.”

From how his bulge slaps against your stomach, so does he. But you feel a moment of doubt creeping in, slowing the roll of your hips enough to squeeze reassuringly at his side.

“But we don’t have to. This is already so fucking good, I just thought-”

“Do it. Fuck me, Strider.”

He practically snarls it at you, the purring coming back full force and shit, you love it when he bosses you around.

“Yessir.”

You kiss him one last time and roll the two of you onto your sides, settling in comfortably. You hike him up a little bit for a better angle, never breaking the grip of his bulge around your dick.

You were planning on grabbing the lube in the drawer beside the bed, but from how much you’ve got splattered on yourselves already, it seems a shame not to use what's at hand. Karkat certainly doesn’t mind as you reach down to slide your hand over his stomach, gathering up as much alien slick as you can. When they slip down and behind him, he practically holds his breath.

You’re not a hundred percent sure what you’re looking for, but winging it has thus far worked out pretty well for you. Much to your surprise, you find something nestled right between his plush cheeks, very reminiscent of your own body.

Perfect. Maybe this part is the… nook?

Your fingers brush against it and he shudders, claws briefly jittering against the skin of your spine. You’re not a hundred percent sure if it’s a good reaction or not, but the noise he makes seems encouraging.

“This okay?” you whisper. He seems determined not to look you in the eye, head tucked into your bicep. Is he just embarrassed?

“Just do it,” he grumbles, a strange chatter vibrating through his thorax. You note how the hair on the back of his neck is standing on end, ears pinned back in a display you can only interpret as submissive.

He arches his spine, hiking his ankles up around your legs to give you a better angle.

“Definitely?”

“Yes.”

He wriggles his hips in annoyance, bulge squeezing instantly at your dick and you laugh, just once, momentary doubt cast aside. You slip one finger over the hole, stroking at it as that strange chittering gets louder.

After a minute or so of coaxing at him, that noise is blended entirely with purring again, and you’re back to grinding on each other as you ease your way into it. Beyond a vague shudder and a low moan, there’s zero resistance when you push your finger inside, opening him up with shallow, careful rubs.

By the time you’ve worked him up to two he’s buzzing non stop, clicking and thrashing at you as his bulge drips all over himself.

By three he’s practically shaking, letting out breathless, frantic sounds that makes you very glad you have the house to yourself.

By four you’re both way too turned on to wait any more. If you don’t get inside him in the next minute, you’re pretty sure you’re going to blow your load and make all this prep for nothing.

Well. Not nothing. You want this image to be burned into your brain forever. You hope the memory of this right now sticks with you until you die.

You force your hand to stop, and when you ease it free he makes a sound like he’s dying. It turns into a much louder, more eager noise as you reach down to untangle his bulge from your dick, guiding it down. The tip of it drags momentarily at the weird entrance below his bulge and he moans, hips squirming in your grasp, but you’re able to line yourself up to his overworked hole pretty easily.

“You ready?”

“For fuh- fuck’s sake, Strider, fuck me alread- hy--”

He moans, loud, as you ease your dick into him, and your mouth falls open with a noise of your own.

It’s different. Instead of the wet, ever moving glide of his bulge, he’s tight and warm and wonderful, aided by your gratuitous prep and equally gratuitous amount of troll cum. You force yourself to go slow, but he just keeps on arching back until you’re buried to the hilt, lower stomach pressing square against that weird second entrance and his bulge thrashing violently over your stomach.

You stay there, trying to catch your breath, drinking in the alien sensation. It’s nothing like fucking a human ass. You’re sure its weird for him as well; the two of you only ever hooked up with your respective species before this. But holy fuck, this is something you could get used to.

You don’t dare to move, but after a few agonising seconds he begins to grind his hips on his own, legs wrapping around your waist to encourage you to join in. So you do. You ease yourself down enough to kiss him and let him set the pace.

He’s taking it like an absolute champ. You adorn his face with kisses, drinking up every noise you’re able to drag out of him as those weird chittering purrs start up again.

You let yourself get lost in it. After a while your hips begin to roll with more eagerness, delving into shallow thrusts and steady pressure. Your stomach is absolutely soaked, bulge trapped and writhing between your stomachs as you lean down to get more leverage, chancing an increase in pace. He moans your name with sudden urgency and you grapple at his sides, kissing at whatever parts of him your mouth can reach.

“Dave- Dave, fuck, I’m going to-”

“Fuck. Yeah, do it, Karkat, you’re so hot, I love you so much, you feel so fucking good-”

“I can’t. I need-”

He grabs your hand, shoving it down towards his bulge. As soon as you reach it, his bulge takes over, shoving your fingers towards the dip just below.

“Inside,” he gasps. “Fuck, hurry .”

Ever the one to please, you slide your index finger in there, curled upward, and he seizes up like a statue.

His head arches back and as he yells, bulge thrashing, and-

It’s like someone dumping a bucket of hot slime on your crotch. Your thrusts stutter as he releases a flood of slurry from around your finger, openly weeping, tears rolling down his cheeks as he squeezes around you so tight you’re momentarily afraid he’ll wrench it off.

You’re not ashamed to admit that this is what tips you over the edge.

Your dick twitches as you spill deep inside him. Whatever noise you make is drowned out by the flood of sobs and moans ringing in your ears and you turn your face towards him, kissing him frantically as the two of you continue to cum your respective brains out.

You start to come down long before he’s done. He looks so good doing it, twitching and groaning over and over again as more continues to spill out of him, dripping all over your finger, your wrist; your forearm. You ease your softening dick from his hole and continue to finger him carefully, working out more and more of that dark red slurry until he’s silent and twitching from overstimulation. Your bed is ruined, but honestly? Who fucking cares.

You lean in and kiss him, easing your hand gingerly from that weird new orifice. His bulge begins to retract immediately, not returning to the place your finger just was, but somewhere… higher? Interesting. You’ll have to do some more research later.

For now, you bask in the afterglow, kissing lazily and enjoying the weight of each other’s bodies.

And eventually, after showering and fully changing the bed, you feel a bit more prepared to go over the events in detail.

He curls up for sleep naked tonight instead of reaching for pyjamas, and you follow suit. You’re a bit too tired to get it up again so soon, but the pressure is nice. You feel so hazy and relaxed, cuddling him from behind as he plays with your fingers.

“Thanks. For today,” he mumbles. His voice has been a little hoarse ever since your earlier tussle in the sheets, which should come as no surprise.

“I had fun. You’re really hot by the way.”

“I know, you’ve been telling me non-stop for the last hour.”

You can’t see it, but you know he’s rolling his eyes. Probably smiling too. You can tell from the soft purrs he’s already making.

“I hope it was okay. Are you sore at all?”

“Not really. Which is surprising, considering. Then again, usually chute stuff is usually reserved for kismesis stuff, and you’re rarely like that with me.”

You don’t fully understand the meaning, but you catch some of it.

“Uh. You mean that wasn’t... typical?”

“No,” he snorts. “I expected you to go for my nook, but I still had a good time.”

Okay. Now you definitely have to do some googling. Get over your weird hangups; you’ve seen him now. Know him relatively intimately in fact. Maybe you could have a proper anatomy lesson,with Karkat as your live model and teacher.

Or maybe it would be embarrassing to admit how little you know.

“Good,” you decide on instead. “Maybe next time we can do it the usual way?”

He turns his head towards you, a slow smile creeping over his mouth.

“Maybe we could start now?”

You meet his eye. Suddenly you have a bit more energy than you thought after all.

This time, you let him roll his way onto you and meet him right in the middle with a kiss.
