For those of you who voted for Dabi on the tentacle poll the other day….I was thinking about the parts I’d written for Eddie when I started to imagine what Dabi might be like in similar scenarios. Thus led me to taking the same idea and apply it to Dabi just…in an alternate setting and…I decided I had to write it. It’s basically the same premise—friends with benefits with a mer!version of a character—but I still wanted to write it for the vibes. So, for the horny Dabi tentacle readers….
Warnings: mer!dabi x fem!reader, nsfw content, tentacle porn (again), public sex (that both r & dabi get off on), dabi puts his hand over r’s mouth, nipple stim, clit stim, penetration (the reader gets fucked by a tentacle idk what else to say here), and there’s like a mention of anal if you squint.
The air was warm on your skin. It smelled of the salt from the ocean—whose waves currently crashed against the nearby shore—and the scent of liquor, perfume, and sex that slipped out of the doors behind you. Loud music shook the building’s walls, vibrating even the balcony you stood on. A moment of quiet away from the noise, the bodies, all that coiled inside the two-story club inside. The empty balcony was a breath of fresh air. And you leaned against the metal railing, dragging your eyes across what little bit of the city there was between you and the ocean.
The moon glinted off the dark water when you heard the hinges creak on the tinted glass door, so dark you couldn’t see in or out of it. A slight, involuntary sigh passed by your lips as you heard footsteps. As quickly as you’d gained your moment alone, a stranger was there to ruin it. You’d give yourself one, two, three more seconds before retreating inside to decide if staying there and watching your friends dance was how you’d wanted to continue your evening. Guiltily, there was somewhere else you’d wanted to be. You hadn’t been able to check to see if your meeting place was still…there. It’d been a year since you’d last been back to the coast, a year since you’d seen him.
And yet, in that year, all you’d thought about were the times you’d come back. Only a month or two in between visits back then. A whole year of just thinking about him. Would he even still be in the area? Would he even still remember you? Would he—
A warm shiver passed down your spine. Hands—warm and rough—came up to your waist. The thin dress you wore hardly kept that familiar touch a secret as his fingers splayed over you. They gathered the fabric up as they skimmed higher, managing to both tug you closer while pushing you against the railing.
“There you are,” he murmured. “Been lookin’ for you all night.”
“Dabi?” you asked, trying to turn to get a better look at him. To see if you weren’t simply mishearing that rough, instantly recognizable voice. And wide eyes found him behind you, hardly able to turn much as he sandwiched you between himself and the railing. “I….”
You shook your head and flicked your gaze down to his legs. Not only was he there, not only had he tracked you down, but he…he was on land? Having legs wasn’t a secret he’d kept; he hadn’t been able to when he crawled out of the water with you to fuck you under the moonlight time and time again. But being so far from the water? It’d never come up, but…you’d always been quick to go to him in the ocean that…guess there was no chance to learn it.
His hands skimmed lower and found your hips, tugging you back as he pressed his forward. A roll of his pressed that familiar feel of his cock against you. Except this time, clothed in thick jeans. A thick belt caught on the back of your dress, and you half considered just turning around and undoing it there.
“Made me go a whole year without seeing you,” he whispered. His lips ghosted over your shoulder. The thing straps kept it bare just for him; his breath fanned against it first, then the curve going into your neck. There was some soft rustling as your eyes fluttered shut. His mouth was a searing hot brand against your jaw. “A whole year without touching you.”
Dabi had never been one to shy away from touching you, regardless of where or when it was. It was part of the fun. Out by yourself during an early-morning swim. Laying out on the shore with a beer, staring up at the stars as the waves tickled your feet. Running out in the waves with friends to ride them with your bodies or simply to relax in some floaties. He enjoyed the risks. He enjoyed slipping your suit off where others might find you and reminding you of what his tongue felt like. In case you’d forgotten.
Out on the balcony, listening to the music shake the walls, was no different.
Something else was, though.
“I didn’t mean to. There were extenuating circumstances that—” Your breath caught as that rustling got louder, and then something touched your ankle. You went still—what the fuck was that? “Dabi?”
An open-mouth kiss found that sensitive spot on your neck as another graze against your legs made you shudder. They were warm and a little wet as they started to curl around your legs. Some thicker than others, and without seeing, you couldn’t keep track of how many there were. But they—something—was climbing up both of your legs with a ginger pace. And they made no effort to slow down as they coiled around your thighs.
“I missed you,” he breathed against your neck, his teeth digging into the tender spot before his tongue drew over it. In a lower, rougher voice, just as the coiling things grazed your hips, he added, “If you keep still, nobody’ll notice.”
If you what?
Oh.
His fingers held you tighter as one of the exploratory sensations brought your attention down to your underwear. What was he doing…? A small curl came next, and you felt it wrap around the back of your thong. Anticipation churned low in your belly as it gradually started to tug up, up, up, until your hips were angled back and your underwear was flush against your cunt. You tried not to hang your head, tried not to let any kind of reaction slip, except the tightening grip of your hands on the railing.
But then another one of those things coiling around your legs moved. The one stayed on your underwear, keeping you angled like a fight caught on a hook, but another…. It went lower and slid between your legs. With writhing motions, it went over your cunt, grinding soft touches against your clit and where you felt yourself clench. Oh, god.
A moan snuck from your lips on a broken exhale, and Dabi pressed another hungry kiss beneath your ear.
“Shhh.” His hands twitched. The tentacles—was that what they were? Fuck. More moved higher. “You don’t want anyone to catch you, do you?”
You. Catch you. He had such little care for getting caught—he enjoyed it. And he knew you enjoyed the risk of it.
Still, your breath hitched when you dared a glance down with the rising tentacles. They left damp streaked behind on the red fabric of your dress, creating a new pattern of all the sinful places they touched. And even when the top of your dress went tighter against you, they managed to slip into it fine. Your stomach tensed at the bulging of them spinning around your midsection before they came up. Without a bra, they had far easier access to your chest. And Dabi hummed with satisfaction as they came right up to them and dragged across where your nipples were already poking through your dress.
“Oh, fuck,” you breathed.
It was barely audible, but Dabi still brought a hand up. Both hands up, actually. One went over your mouth—as if that wasn’t obvious enough to what you were doing—and the other slipped beneath the strap of your dress.
“Shhhh, (Y/N).” The tentacle running over your cunt pressed harder and moved faster. You moaned against his palm involuntarily at the feeling. “I haven’t even gotten started yet.”
Your nipples were tweaked and tugged beneath your dress, giving way to the sight through the material. You tried not to watch, but if you kept your eyes out at the city, you caught those walking by on the sidewalk. You were far enough away that they wouldn’t see anything but two people standing on a balcony and enjoying the view. They probably wouldn’t even be able to make out Dabi’s hand plastering itself over your mouth. It was entirely nonchalant and innocent from their point of view. But, still, looking at them as the tentacle between your legs moved and slowly tugged down on your underwear? Heat shot itself across every inch of you.
Dabi tugged one strap of your dress down, then the other as you were guided out of your underwear. Your heels were loud on the floor, and stepping when you had multiple tight tentacles coiling around your legs was more than difficult. But that wasn’t the worst of it. The second Dabi tucked your underwear into his pocket, the second his mouth was back on your neck, he pressed his hand tighter against your mouth.
“Oh, fuck,” you spat against it, eyes shutting as the tentacles moved. Higher. They parted you, one writhing over your cunt with precise movements, grinding against your clit again and again until you were starting to pant. But it wasn’t there permanently. Those drags were changed, and in came a small tentacle, the diameter a fourth of the size of the last one, and it curled around your clit. Coiling, circling movements gave it direction attention, and the ones capturing your legs didn’t have to pull them open for you to spread yourself. You were already doing it, leaning more over the balcony and basically presenting yourself to Dabi.
He grinned against your shoulder, nipping at the skin your strap had been covering.
“Take it,” he muttered, and there was nothing you could do but shudder. A moan was muffled against his palm in the process, and you earned another searing grin. “That’s it—take it.”
Another larger tentacle came up, and his words rang with a different intention. One that made your heart race as fast as the music’s tempo still reaching the two of you. Your clit was stroked faster, harder, and your thighs were already shaking as your climax got closer. Your knuckles ached under the harsh grip you had on the railing, but Dabi wasn’t letting up. In fact, he was pressing in.
It was larger than his cock; you knew that much. And you stretched around it as he pressed it into you. Wet and smooth, you took every inch he gave you of it. More, more, and more that already had it pumping inside you. Slow drags that went deeper than you’d felt before and then all the way out until you were far too empty. The wet sounds were vulgar and loud. Even someone just poking their head out would hear them. Hell, they’d see you bent over the railing, ass pressed back against Dabi’s lap, moaning into his hand as he fucked you with a part of him you never knew he’d had. Based on the fresh air occasionally hitting your upper thighs, anyone who looked out the door would see the tentacle pumping into you.
Your thighs were a sticky, wet mess, but it was hard to care. Your dress started to fall down your chest, every curl and tug of the tentacles against your nipples only working to bring it lower. And since Dabi seemed to have little care in pulling your straps back up, you were blessed with the brief sight of the tentacles that went higher over your chest when you dared a look. Your chest expanded with every heaving breath, and one too many flashed you the sight of the tentacles that were the same color as the abyss of his midnight hair. They tweaked your nipples hard, and…didn’t release. Not yet. Not until you were fully leaning over the railing, your dress damn near around your waist, the only thing working to keep you covered was the spread of your arms with your grip going wider. The straps caught it, pulling it back up just enough.
“Dabi,” you whined against his hand, and a teasing kiss went to your back, right between your shoulder blades.
You clenched around the tentacle inside you, your knees threatening to buckle as every thrust working in tandem with the one on your clit had tears springing from your eyes. Your friends would come looking for you soon, wouldn’t they? It was only a matter of time before they realized you’d disappeared for much longer than one needed to use the restroom. And if they found you like this…?
Another tentacle moved. You…you could hear yourself dripping down onto the floor below with every thrust of the one that nearly had you screaming. Fuck. Every wet sound sent flames to your cheeks, and you couldn’t do it. You couldn’t look out over the dozens of people walking on the sidewalk; just one look away from seeing you getting absolutely worked over by Dabi. Your nipples were tweaked again, and there was almost a new sucking kind of sensation against your clit. It felt eerily close to when Dabi closed his mouth around your clit, and that….
“Oh, fuck.”
That was it. Dabi pulled the back of your dress up and leaned back as you clenched hard. Every muscle in you tensed as every thrust got deeper and harder, as every thrust went right for the spot that had your clit throbbing under that sucking sensation. That had you gushing and trembling as your orgasm rushed toward you. The sudden feeling of nothing covering you sent pure adrenaline through your veins, and feeling Dabi’s burning stare over your cunt? Over where he brought his hand so he could angle your hips into the perfect position to really see you take him again and again, gushing over him just like that.
You couldn’t hold on.
Dabi hardly bothered to really cover your mouth as you gasped against his hand, the sound turning into a high-pitched whine next, one that broke into multiple as that tentacle fucked you harder. Rougher. Every sensitive part of you was touched, sucked, tweaked, and fucked. Even that extra tentacle went into the small space it could fit in between where Dabi had stepped back to look at you. And it curled against the sensitive skin on your other hole, only barely pressing in where you were clenched hard with your climax.
Fuck. Fuck.
Mascara stained your cheeks as tears slipped down them.
And the tentacles slowly came to a stop with their torment, but they…didn’t pull back. They stayed around you while you panted, eyes opening to blink away blurry vision as you stared at those wandering the city. Dabi’s hand lowered to rest on your throat, and you swore you felt him hum a happy growl as you swallowed hard before continuing to huff. You were still stuffed, the tentacle slowly squirming inside you, occasionally brushing against the spot that had you twitching and gasping while you tried to find words to fill the silence.
After a second, your dress was lowered, and you felt Dabi step closer, his cock hard against your backside. He slowly began to grind against you, moving in time with the writhing tentacle inside you.
“Meet me in our spot,” he whispered, letting all the tentacles move again. Tweaking, sucking, stroking, pumping. You shuddered hard, and without his hand to cover your mouth, your gasp was loud into the night air. And yet, almost the moment they started moving, they stopped. They pulled back rather suddenly, and as soon as you’d been tangled and filled by them, they were gone. Soft rustling came through, and then all you were left with was their sticky residue. And yours. You…actively dripped down your thighs as Dabi stepped back, barely bothering to help adjust your dress. “I’ll give you an hour.”
His warmth was gone a second later, and as you frantically peered over your shoulder, trying to process everything post-orgasm while sopping wet, you caught his mischievous grin. He briefly spun your underwear around his finger before it was tucked back into his back pocket. A burning look with those impossibly blue eyes had your knees buckling, and with a swift pull of the door, the music blared, and Dabi disappeared into the darkness.
Damp streaks were left over your dress, and your thighs were sloppy, sticky, and wet as you slowly turned, leaning your weight against the balcony. Another breath shuddered from you while you fixed the last bit of your dress, bringing your hand down to keep the wind from bringing the skirt portion up.
What the fuck?
You blinked at the dark door, adrenaline pumping. Your cunt already ached for that sensation again. For…all of it again. For him.
One hour.
You stole a glance over your shoulder, catching the moonlight on the ocean while you rose to your feet. The hunger in your veins grew with excitement.

Excited by the possibility, you decide to visit Universal Aquarium after your last final, taking a leisurely walk around to look at the types of fish you may get to work with, only to find that one of them is probably far, far beyond your paygrade…
… or where you are a degree-holding fish nerd who unknowingly begins to work at an aquarium that wasn’t originally created to be an aquarium, and you catch the interest of its sadistic, biggest-kept secret.
(Warnings: mentions of forced orgasms done secretly underwater around friends, multiple orgasms, gn!reader, written while verrrrry tired )
Thinking about how mer!dabi would definitely be the kind of asshole who’d sneak up to you when you’re in the water with friends. He wouldn’t care to let you know that he’s there until the penultimate moment. And he’d do his best to make sure he wasn’t too obvious with his movements beneath the water until, suddenly, whatever you were trying to say gets interrupted by the feel of someone tugging your suit down. But you’re in far too deep of water, and you would’ve noticed if some asshole swimming suddenly showed up to try and perv on any of you.
Arms around an inflatable tube, you’re just about to glance down to ensure there hadn’t been a wardrobe malfunction when you feel his hands. You know his hands. And you know his mouth even better. Before you can even get your head wrapped around it, there’s Dabi. You know it’s Dabi—there’s no one else who holds your hips like he does. No one else who’d be able to slip beneath the water and remain there as they draw their tongue over you. You try not to squirm, listening to your friend just a few feet away recite some story. You try not to splash or suck in too sharp of a breath or curl into yourself as the pleasure begins to rise. You don’t try and kick him—it might cause people to know what was happening. Or they might even look beneath the water and find out your secret.
So you’re stuck there, Dabi’s fingers digging into your hips as he holds you against his mouth. His tongue. His low growl that shoots vibrations down to where you ache and throb. You’re stuck there trying not to cum as Dabi seems dead set on making you do exactly that. He’s rough with his movements, pushing you closer to what you’re trying to stave off. You’re trying to answer a question posed to you when he adds more suction, and you stumble over your words.
Because mer!Dabi is the exact kind of asshole who’d push you toward a mind-shattering orgasm while you were around your friends. And no matter how hard you try to stave it off, Dabi’s stubborn. Dabi’s on a fucking mission. Mer!Dabi’s the kind of asshole that makes you cum. Forces that orgasm out of you no matter how hard you try to stay composed. And it takes everything in your power to not give a reaction. You’re clutching your tube to the point where you almost pop it as you tremble, already overstimulated as his tongue works you harder. You can feel his grin, but you say nothing. He wouldn’t be able to hear anyway.
And just when you think you’re out of the woodwork, he…he doesn’t stop.
Dabi keeps going.
You’re clenching your jaw as he continues to work you without pause—without even a single breath of a break.
Until you’re trembling so hard, you know someone’s going to notice. Until you’re sinking deeper into the water as you fight involuntary moans. Until you’re feeling another build of pressure while pleasure ripples out.
You pretend you’re scratching at your jaw when you cum again, biting at your knuckle when nobody’s looking just to shut yourself up.
And there’s a pause. Enough of one where you think he’s left. Slipped in to make you climax twice, then leaving to figure out how to tease you about it later. Except….
As you start to take a soothing, relieving breath—you feel him again. Lapping, sucking, tasting. Softer than before, but it’s still too much. A low sigh starts in your chest, and it pinches hard next when it tries to become a moan.
And he doesn’t stop.
Because mer!Dabi is 100000% the kind of asshole who’ll force orgasm after orgasm out of you just to see how much you can take before your friends start to catch on.
