Work Text:
You make eye contact with yourself in the mirror from behind your shades. An embarrassed smile is tugging at the corners of your lips.
“Shit, what do people usually do here? Uh. Rules? A) No going to bed before you can suck down to here,” You mark the spot on the toy for yourself with your finger. “B) If you feel like you're gonna hurl, drink water then get back to it, and C) have fun and be yourself.”
You look at the dildo in your hand. It's around 12 inches long, not tapered and most certainly not prehensile, but you take what you can get. The technology and demand for troll bulge-shaped dildos haven't quite taken off yet.
“Karkat had better fucking appreciate this.” You grumble to yourself, looking back up at the mirror.
You lick a stripe up the bottom of the dildo, since you've seen people do that in porn. This really is pornographic, huh. It's like you're being filmed for some creep to watch at home. Or read, maybe?
You swirl your tongue around the tip. It's already daunting. You lower your head around an inch, taking extra-special care not to scrape it with your teeth. Wouldn't wanna skin his bulge the first time you suck it.
As you take another inch into your mouth, you feel your teeth make contact with the toy. You roll your eyes.
“Rule D: no teeth,” You say as you take the toy out of your mouth. “or we start from the top.”
You close your eyes so you can picture Karkat at the other end of this dildo, his sounds, his hips jerking a little as he tries to keep still and not kill you. His alien bulge squirming around in your mouth. Dripping bright red genmat.
You've tasted his genmat before, obviously, you weren't gonna pass that up when you fingered him that one time. Surprisingly, it tasted like those little fucking cherry sour candies you can get at the drug store. You licked your hand completely clean, not just because it grossed him out and made you laugh, but because it tasted really really good. You try to picture that flavor as you coax more of the toy into your mouth.
You imagine him fisting his hand in your hair as you do so yourself. Him pushing your head further onto his bulge by the hair, and you do the same with the toy. Having Karkat in your mouth in your mind palace makes this a lot easier. That's a true statement in general.
The toy hits the back of your throat, and your stomach lurches. You let the toy fall out of your mouth and get a glass of water, and several more after that.
“Fuck this. What am I doing.” You say, going to put the dildo back in its box. Then you picture Karkat falling apart under you, looking down at you, eyes foggy with lust, and you decide against it.
You lather a little more spit on the dried-up head of the toy to make it easier for yourself. Hollowing out your cheeks (you think that’s what you're doing?), you lower your head back down as far as comfortable. This next part has proven to be harder than the others, so you brace yourself on your counter and try to get the dildo in your mouth further than last time.
You feel queasy, but you try to push past it, imagining Karkat biting his arm to keep quiet. And, naturally, failing to do so. Guy's never been quiet in his entire life. You try to imagine what sounds he would make as his bulge gets further into your mouth, close to your throat. You gag as it brushes the back of your tongue, but you wanna go to bed, so you breathe through the nausea. Ugh.
You swallow thickly as it touches the back of your throat. You feel a little lightheaded, it's hard to breathe. You let yourself bob up and down so you get a chance to take a breath. Karkat had better appreciate your bulge-sucking game by the end of this.
Curious about how this is affecting you, you look up at yourself in the mirror. Your cheeks have a dusting of pink on them, tear streaks trailing down them. Your hair is a little fucked up, from the hand you put in it earlier. Your lips are red and glistening from drool. Damn, ok, you look hot like this.
You try to push the toy further into your mouth, but you feel your teeth scrape it. God dammit, fucking hell, etc. You pull the dildo out of your mouth with an eye roll.
“Come on, man, you were doing so well.” You scold yourself in the mirror.
“Seriously. How hard of a rule to follow is ‘no teeth’, Strider.” A mystery voice says from the doorway. You try to decaptchalogue your katana on instinct, forgetting the fact that you don't have one. Fuck, ok, guess we're fighting with this dildo then. You hold it up like a sword and turn to face your aggressor.
You're met with a smug-ass looking Karkat leaning against the doorframe. You can tell he's thinking “how are you gonna use that toy as a sword”. Shakily lowering your improvised weapon, you take a step forward.
“Jesus fucking Christ, Kat, you can't just sneak up on me like that.” You say, adrenaline evident in your voice.
“If you wanted to practice, you could have just asked. I have a perfectly functional bulge you can use.” You look down. His pants are fucking dripping red. “Not that I don't appreciate the personal show.”
“Shit, sure, but I gotta warn you I've only been practicing for like 10 minutes.” You say, wiping your mouth.
“Dave, you have been in here for the past half hour. I think that's enough practice.” You raise your eyebrows. You had no clue you were in here that long. “I obviously got a little fucking concerned, so I came to check on you and saw you, yknow, sucking off a sex toy. I was gonna wait until you noticed I was there to say anything.”
Karkat walks over to the toilet and sits down. He pulls down his sweatpants, and a steady trickle of genmat starts to drip into the bowl. You really, really want to get your mouth on that.
“Get over here, then.” His facade drops as you realize you talked about wanting to suck him off out loud just now. His eyes go half-lidded.
“Yessir.” You say, and kneel in front of him. He smiles down at you and brushes your bangs back, getting a good grip on your hair. Wow, you didn't expect to be this into that in practice.
At eye-level with Lil’ Karkat (his bulge's new name), you realize you somehow weren't practicing on something big enough. Jesus Christ, how does all of it even fit in his sheath? Especially considering how small the rest of him is. You guess that's just a mutant thing? While everyone else gets bigger every molt proportionally across their body, his bulge just gets bigger? Weird.
“Stop talking and put my bulge in your mouth already.” Karkat says, snapping you out of your thoughts. Which you were voicing. Again. “Also, don't call it that.”
“Aw, but Lil’ Karkat is such a cute name!” You pout. He glares at you, and tugs at your hair in retaliation. You whimper quietly.
“Oh my Gog. You like that, Dave?” He teases you. He must have super hearing or something, goddamn.
Before he can say anything more, you lick along the bottom of his bulge like you did with the toy previously. His words catch in his throat and his grip on your hair tightens. Now you're the one smirking.
“Since I'm practicing on the real thing now, tap twice if my teeth are on you and three times if I need to let go. Four times if you're gonna come so I can prep myself.” You sit back on your calves while you list these, watching him grow more and more impatient. The rules are important, yes, but you're mostly taking forever to bother him.
“Yeah. I get it. Please just get the fuck on with it already.” He says, voice thin and wobbly.
You open your mouth up and let his bulge find its own way in. It's pretty cool how it can find your mouth just by sensing the heat or some shit. You close your mouth around it as it wiggles a little further in.
“Hnh, Dave, fuck…” He pushes your head down a little further, then seems to realize what he's doing and backs off. “Can I move?”
You hum in agreement and nod. This time, both hands find their way into your hair, pushing you down while his hips jerk up desperately into your mouth. You gag a little, but moan a lot more. His sprawling vocabulary has seemingly disappeared in favor of “fuck, Dave, oh God, Dave, fuck that feels so good, you're doing so good Dave,” repeated like a prayer. The praise goes straight to your dick, and you find yourself reaching down to touch yourself.
With your fingers up your front hole, heel of your palm grinding against your dick, Karkat's bulge in your mouth and hands in your hair, everything borders on too much and it feels so good you could cry. Are crying? You feel liquid drip down your cheeks, not just the expected sweat and drool and genmat. You worry that you're turning Karkat off, despite all physical evidence to the contrary, so you look up at him.
You almost come on the spot, looking at the way he looks at you. His pupils are big blown out circles, overtaking nearly all the color around them. He bites his lip so hard the sharp fang draws blood. His cheeks are flushed, shiny with sweat. You moan around his bulge, and it descends down your throat a little further as he lolls his head back.
“Dave, fuck, can you…” He detangles a hand from your hair to mime fingering him. You immediately get your hand in there, thrusting at the same pace as you're doing for yourself. “Yeah, just like that, God Dave,”
The coordination required to finger both of you at the same time takes any focus you had on sucking his bulge properly away, but that doesn't seem to be much of an issue. He holds your head in a vice grip and does all the work in that department for you. You close your eyes and moan again, speeding up your hands on the both of you, maybe a bit more cruelly on yourself. You're so close, just a little more.
“Daave…” He moans, voice broken and rough, and it sends you over the edge. You're lucky he's fully controlling your head at this point, because you're not sure you wouldn't have tipped your head all the way back without it. You grind down on your own fingers viciously as you cry out, high and needy.
He taps your head four times, but you don't pull your head off of him, hoping to swallow down as much of his sour cherry genmat as possible. He buries his bulge in your mouth as it starts to swell slightly, leaking genmat out its pores, then drops his chin down to his chest with his mouth open in a silent cry as he spills down your throat.
You're drowning in him, getting strangled by genmat as he continues to spill, petting your hair soothingly. You know most of the liquid is dripping out your mouth onto your shirt, you can feel it. You can't breathe. Your vision goes dark around the edges.
His bulge finally retracts into his sheathe. You slump forward to rest your head on his thigh, coughing, attempting to catch your breath. His claws card through your hair, working out any tangles he might have caused. It'll fuck up your curls, but that's nothing washing your hair can't fix.
“You did so well, holy fuck. Are you ok?” You nod your head lethargically. You've been better. It's really late. “We should go to bed.”
He pushes you back by the shoulders gently, so you sit on your calves, as he stands up. Gently again, he helps you up to your feet. You rest your head on his shoulder and he starts purring.
“C'mon, dipshit, 15 more steps.” You lean your weight on him obnoxiously and he rolls his eyes, still purring. He murmurs “asshole” under his breath, but helps you walk the rest of the way anyways.
