How to Summon a Succubus

Ft. Yamaguchi Tadashi x succubus!FEM!reader, Tanaka, Tsukki, Noya

Summary: Tadashi’s friends try to summon a succubus to get him laid for the first time. Unexpectedly, it works.

In a world of the supernatural, there were many different races and species and sub categories. Probably hundreds. But still, there were very few of you. You'd think the humans were weaker compared to the rest of the world, but them themselves held a power hard to beat.

In the 8,000,000,000 people on Earth, only about 4% of the people people living on it were of the supernatural. Still, most of them had rights and lived normal lives despite it.

You, on the other hand, had a harder time. 'Unnatural' skin covered your body, and two horns laid atop your head. Your heart-tipped tail swayed behind you as you walked, and left nothing to the imagination as to what you were. A succubus.

Parents hid their children from you, and avoided all eye contact with your unnaturally bright eyes. Refused jobs and services, kicked out of shops for 'suspicious activity', and immediately under suspicion if any sexual predator was on the lose.

You followed in your parents' footsteps, helping out at your eighth generation family business (if you could call it that). You sat on the receptionists chair, pretending to be busy so the clients in the waiting room in front of you wouldn't bother you. The government checked the place three times a year to make sure it was top-notch and in perfect shape, eyeing the smallest details to ensure nothing was amiss. Of course, they were only doing this because brothels like yours were in such high demand for humans.

"Welcome to The Bat's Wing, how can I help you?" You answered when you picked up the phone. "Summoning? Gosh, I dunno. Hasn't happened in hundreds of years so no one knows if it's a myth or not."

Obviously, you knew about summoning. It was a secret so buried that it was almost impossible to find out about.

"Oh? For your virgin friend?" You leaned into your desk, eyeing the entrance way through the glass separating the two rooms. "Well, he could always come and book an appointment. Too shy? Aw, what a shame. I love the shy ones."

"Alright then, Tanaka, you'd better have a good story to convince me," you listened intently. "Ah, well it seems as though you're on the right track. Do some more digging around the Meru bloodline and see where that takes you. Mhm, yep. Ok bye."

Ok so, you weren't exactly the best secret keeper ever. But dropping hints wasn't exactly exposing the secret, right? It's not like they'd be able to figure it out. 'Blood of a virgin'? Pfft, more like semen of a virgin.

"Why are you guys making me do this again?" Yamaguchi blushed as he sat in front of a pentacle drawn in chalk.

"Because you're the only virgin in the group!" Noya flailed his arms.

"Yeah, even The King has lost his," Tsukishima mumbled from the corner. "Just thought I'd help you out. Tanaka and Noya seemed like the only people who knows about this summoning bullshit."

Yamaguchi gulped and turned back. "What next, then?"

"'A tuft of the summoner's locks'," Tanaka recited from the sketchy old photo of a parchment he found after days of digging, "on the tip of the pentacle."

Yamaguchi snipped a patch of his hair right behind his ear, and laid it down on the silver plate. He followed with a vase of feathers on the left point, then a goblet of wine on the opposite side. Next was a bouquet of some very specific flowers on the bottom left, wrapped in a natural cotton cloth. In the right bottom hand point, he lit four candles; white, black, pink, and red.

"Anything else?" Yamaguchi sat back on his haunches.

"Um," Tanaka side-eyed Noya and Tsukishima. "Ok don't freak out, but a 'nip glass of a virgin's blood'."

"What the hell's a nip glass?" Tsukishima what everyone was thinking.

"Google it," Noya shrugged.

"Oh. It's a shot glass," Tanaka answered.

"A shot glass of my blood?!" Yamaguchi yelled. "No way! I'd have to really cut myself to get that much!"

"Well fuck," Noya groaned. "Where's the least damaging place we can—"

"I said no," Yamaguchi growled, glaring at his friend. "Any alternatives?"

After lots of thinking, and dumb ideas, Tsukishima finally spoke up and said:

"Well what about semen?"

Everyone stopped to stare at him, mouth's agape. Noya and Tanaka whipped their heads to Yamaguchi and he sighed.

"Fine. Better than blood," Yamaguchi begrudgingly agreed. Maybe then it won't work.

He padded up the basement and grabbed a shot glass before locking himself in the bathroom. He looked out to the bright full moon, and wondered how he got himself into this mess.

"Here," Yamaguchi said, firmly placing a shot glass of his cum in the centre of the pentacle. "Now what."

“I can’t believe you actually did that,” Tsukishima grimaced.

"Here," Tanaka passed Yamaguchi his phone. "Read the poem or whatever it's called."

"'A woman of desire, o' cometh to my side,

To aid me in my deepest dreams,

And to feed thou of what thou doth need’," Yamaguchi recited, squinting at the slightly blurry penmanship.

"'No needeth a cry,

No needeth a whip,

Cometh to drain me

Of my pastorship.'," he continued.

"'O' skin of flare,

And eyes o' rare,

I give you my word,

I'll provide you the cure,

O' thous' desire.'."

Yamaguchi continued down the paragraphs, blushing at certain parts, and finally reached the end.

"'O' woman so fair,

I'll lend thou mine care,

O' my phallus so heavy,

To send thou a sign,

So thou can come find me.'."

"Whatta bunch of bullshit," Tsukishima muttered.

"Ok folks, let's go and leave Yams to slumber,~" Tanaka sang as he dragged the two other boys along.

Yamaguchi gulped.

It began with the tingle of your toes. You thought nothing of it other than you were probably getting hungry again. A heat trailed up your body and you shivered in arousal. That was the second sign. It was almost instinctual how you rummaged through your drawers to find the perfect set of lingerie, not even knowing what you were looking for. The black set felt nice on your curves, and you threw over a sundress.

Your eyes grew bright, and you could see a shimmering light about a mile from your window. You blinked in surprise that whoever had attempted to summon a succubus had actually succeeded. You grinned. A nice shot of cum was waiting for you.

Slipping out of your window with a pair of sunglasses to hide your bright eyes, you made your way down the dark streets, following the faint glowing light that carved your path.

You stopped abruptly, and a sharp 'ZZIRP' noise rattled your ears. You opened your eyes to a dark room, save for the candles that were still (unsafely) lit. The boy you were here for was in his deepest REM sleep, and you felt giddy all over. You wondered what your fellow succubi would think when you went back and told them you had been summoned. You leisurely stepped out of the pentacle, careful to avoid the goblet of red wine. You pinched the flames with your fingers to put them out, and picked up the goblet.

You hummed as you sipped on the liquid, a very specific blend that you could recognize anywhere. After drinking the whole thing, you turned to the flowers. They were beautiful, and smelled of lust and nectar. The feathers were a nice touch, and you pinched the lock of hair on the silver plate. You realized that your sunglasses were long gone, as well as your dress, as you admired the fluffy green-grey hair. It smelled faintly of pine, and something warm you couldn't quite place. Finally, you plucked the tiny glass in the centre of the pentacle and grinned. The smell was intoxicating, and it made your heat throb excitedly. You used your finger to scoop out the cum, groaning each time you sucked the sweet nectar down your throat. Your tongue elongated as you licked the glass clean, not wanting to waste a drop of the sticky substance.

In a haze, you dropped the glass and wandered up the stairs of the basement. The door to inside was locked. No matter, it was probably just habit. You flicked your finger and the door opened with a quiet creak.

You admired the photographs on the wall as you wandered upstairs, smiling giddily when you saw the summoner. He looked like a sweet young man in his most recent pictures, and you gathered that he was still staying at his parents' house for whatever reason. The door of his room glowed, and you carefully slid it open to reveal a young man cuddling his pillow, sound asleep.

You slid the door shut behind you, and walked over to the foot of his bed. Eagerly, you trailed a hand up his bent leg and urged it to lay straight. Once it did, you hovered over his legs and used a finger to gently rub the front of his briefs. You moaned quietly as he hardened, and you hastily removed his underwear. You touched him some more, and his cock quickly throbbed upright. Precum was already drooling out of his slit.

"Hmph?" A very tired and confused Tadashi mumbled as he used his forearms to sit up, eyes blowing wide once he saw your hovering figure. He was speechless.

You grinned wickedly at him, waving playfully before moving your hand back down to grip the base of his cock.

"H-hi?" Yamaguchi squeaked once he came-to.

"Hello," you giggled. "It seems as though I've been summoned."

Yamaguchi could only stare as you greedily licked a stripe up his shaft, a soft moan emitting from his lips.

"What would you like me to call you, Summoner?" You hummed, nonchalantly pumping his dick.

"Y-uh you can uh, c-call me Tadashi," he stuttered out, squirming in place when you played with the head of his cock."I- ah~ -didn't think it w-would actually work."

"Well I'm happy it did," you grinned. "Working with a virgin isn't something I've done before. Plus, you're cute."

You beamed as he flushed, half turning his face to hide it. Yeah, you were definitely going to enjoy yourself. Tadashi finally took a good look at your appearance, throat going dry when he realized that you were barely covering your body, clad in only a black lingerie set.

"Like what you see, do you?" You smirked, walking your fingers up his shaft. You tapped lightly on the head of his cock, his pre sticking to the tip of your finger.

He stared in awe as you collected more of his pre, bringing it to your tongue. You moaned softly at his taste.

"I've already had a little taste earlier," you purred, nuzzling your cheek on his cock. "And I'm already addicted."

Tadashi's face glowed pink at the indication that you had drank the little shot glass of his semen, mouth gaping as you kissed sloppily up his shaft.

"W-what's your n-name?" Tadashi stuttered out, fists gripping his blanket under him.

"Oh how rude of me. My name is y/n," you licked your lips, giving him a wink. "But you can call me anytime."

Yamaguchi didn't have a chance to respond before you wrapped your warm lips around the head of his cock, quickly working your way down so you swallowed around his whole length.

"Ooah," Tadashi moaned, his head lolling back. He had never felt such a sensation, his body already shaking and close to orgasm.

You slurped greedily on his cock, the promise of his delicious sticky cum all too much to make you slow down. You slithered your tongue wherever you could, tracing the veins along his length.

All Tadashi could do was throw his head from side-to-side and firmly grip his bedsheets. Groaning unintelligibly, he flopped totally on his back and struggled to stay still, harshly trailing his hands up and down his body to grope at his skin.

"Ffffuuuuck," he keened loudly as you hummed and swallowed around his cock one more time before he came, warm ropes of cum going down your throat.

You sat back and watched as the boy beneath you slowly came-to, heaving for breath and eyes tightly closed.

"Sh-shit," he sighed quietly, heavy lidded eyes looking up at you.

"How was that?" You grinned, resisting the urge to continue to play with his sensitive dick.

"I-I can't even—" Tadashi struggled "—begin to explain how good that felt."

"You're about to feel so much better that that," you promised. "Trust me, I'm just getting started."

"I-I dunno if I can..." he began.

"Don't worry, my saliva will keep your stamina up," you pulled yourself onto his lap.

"Can I um... can I kiss you?" Tadashi asked nervously.

"Mmhm," you leaned closer. "You're such a good boy, Tadashi, asking so nicely."

Tadashi whined at the praise before you muffled his noises with a kiss. You could tell he was inexperienced from the way he nervously moved his lips with yours, but you didn't mind because it was kinda cute.

"Open," you said as you pulled back.

Tadashi did as he was told, and your tongue lulled out of your mouth to let a long drop of saliva to enter his mouth. The sweet taste of your spit made him moan in surprise, but you cut him off when you smashed your lips to his yet again.

"Touch me, Tadashi," you hummed lewdly, your eyes glowing.

Again, he did as he was told and let his hands trail over your figure, stopping at your waist to pull you closer.

"Fuck, I love how obedient you are," you groaned. "Such a good boy for me."

Tadashi's cock twitched, and you used your tail to reach down and pump his length. You swallowed his moans, elongating your tongue to explore his mouth. The feeling of your tongue gliding against his was enough for him to jerk his whole body, coming with a loud whine. The end of your tail opened as a second mouth, and it slurped up all of the cum it could.

You leaned back to admire Tadashi; his eyes were heavy with lust, and his cheeks were painted a pretty pink. His lips were swollen and shiny from your kisses, puffy and red. He had a calmer aura after you had kissed him, your saliva easing him into the lull of your dance.

"Ta~da~shi~" you hummed, trailing a finger down his sternum. "I bet you want to see what's underneath my outfit, hm?"

"Y-yes please," Yamaguchi nodded.

His heartbeat sped faster when your clothes were stripped from your body with a flick of your tail. He wanted to touch your breasts, the perky nipples of your tits causing his mouth to water.

"Do whatever you'd like," you purred, gloating in his gaze.

"Y-you're sure?" Tadashi gulped. "W-what if I—"

"Baby, look at me. I can overpower you in an instant," you grinned. "Trust me, I can stand up for myself. I'm a big girl."

Tadashi gulped anxiously as he reached his palms to your breasts and gently squeezed, marvelling at the feeling. You pulled his face flush to your chest, and you encouraged him to suck and kiss your tits.

"Good boy, juuust like that," you ran your fingers through his hair. "Your tongue is so soft."

Tadashi could only whine in response, his hands trailing down to your hips. "C-can I go in-inside?" Said his muffled voice.

"Oh, absolutely," you purred. "G'na fill me up so good, Tadashi."

You reached your hand down and wrapped it around his cock, giggling when it twitched in your palm. You pulled back so you could look at his face, grinning as he watched in amazement as you slowly dragged the head of his cock over your swollen bud.

"Mmm," you hummed, biting your lip. His eyes met with your half lidded ones, and he gulped nervously.

A loud keen echoed through the room as you inserted his glans inside of your pussy. "Feels s'good already," Tadashi moaned.

You watched contently as his face contorted in pleasure as you sank further down his shaft. You reached for his cheeks, and rubbed a tear away. Sometimes you forgot that human pussies couldn't compete with a succubus'.

"Holy fuck, holy shit," Tadashi's back arched and twisted as you let him get used to the foreign feeling. His breathing was ragged and his eyes were half shut in pleasure.

Once you were fully seated, you felt Tadashi's cock twitch once, twice, before spilling his load inside of you. Your body shivered in delight as the man beneath you gripped the sheets beside him.

"M'sorry," Tadashi mumbled. "'S my first time."

"Don't be sorry, baby," you cooed, holding his freckled face gently. "We have all night."

He whimpered when you began to move, eyes closing tightly for a moment. "Fuck," he said in a small voice.

"Mm, you fill me so good Tadashi~" you moaned into his ear, gently nibbling on the soft cartilage. You pulled back to look at his blissed-out face. "Shit, you're cute."

"Hnngh," he whined in response, eyes glossy with tears. "F-feels really good."

"I could fuck you forever," you sighed dreamily, rolling your hips in a circle. "I want to make you feel so good that you can only get off to the thought of me. Oh shit you feel so good."

Tadashi looked up at you with his watery eyes, awe still painting his face as he weakly tried to thrust his hips up to meet yours.

"Relax, baby," you purred, holding a hand to his heaving chest. "I got you."

You could tell that his body was just about done by the way his limbs weakly grasped onto anything they could, and how his eyes were almost closed.

You leaned down to kiss him, giving him more sexual energy with your saliva so he could have one more orgasm.

"Ffff-shit!" Tadashi wailed, back arching as his eyes rolled. "S-so... sho good."

Stomach twisting pleasantly, you finally allowed yourself to relax and ride your incoming orgasm, watching Tadashi with heavy eyes as he writhed and moaned lewdly beneath you.

"Fuck, m' gonna cum, Tadashi," you practically growled, leaning in close to suck and nibble on the skin of his neck. "Cum with me, baby."

Tadashi whimpered loudly at your demand, and he cried out as his cock forced out another load of cum into you. Your body shook and you quickly rubbed your clit, body shaking as you moaned in delight as your pussy sucked up every drop of cum it could. When you came down from your high, you looked down to see Tadashi dead asleep, snoring adorably with a line of drool on his chin. You cooed at his relaxed form, still sweaty and naked.

You tidied up what you could, before deciding to cuddle up beside Tadashi as he slept peacefully. You pulled the comforter over the two of you, and you admired the boy beside you before you yourself fell asleep to the sound of his heartbeat.

That’s the thing about a/b/o; it’s such a good vehicle for certain kinks. I’m just going to go with the first half of the list and say Tsukkiyama… any of: 6, 11, 14, 19 or 28.

Any, some, all or none! Up to you!

All of your fics are great!

This is exactly my thought. I picked two of the ones you sent from the prompt list, feel free to send more if you want!

Here’s the ao3 link 

- MINORS DNI -

Tsukishima Kei is not prone to letting his emotions or his instincts get the best of him. It’s tiring, and just not worth it most of the time. Often, this isn’t an issue; he doesn’t feel anything too strongly, and he’s not exactly eager to get into just any omega’s pants, so even when an omega goes into heat in public he’s able to keep a level head. He doesn’t feel that primal urge inside himself to claim, to mate- 

Or, at least, for the most part. It’s becoming more of an issue lately, and it’s frustrating. He doesn’t know what it is, but lately whenever he finds himself out with friends, he’s just the slightest bit annoyed, just a little more prone to snapping back. He chalks it up to just having outgrown the idea of going out every weekend now that he’s an adult with a job, and yet whenever a certain childhood friend of his asks him to come out he does without hesitation. 

...Which leads to his other issue. 

Yamaguchi Tadashi has always been a soft spot for Kei, he’s always wanted to protect him- ever since they first became friends in elementary school. Now that they’ve long since graduated highschool, and recently college, however, it’s becoming increasingly obvious that Kei’s soft spot for Tadashi is more than he lets on. And Tadashi has always been naïve, but it’s never been more aggravating to get him out of the situations he manages to get himself in when he’s a little tipsy. And Yamaguchi likes to let loose on the weekends. 

And letting loose he is. 

Kei hadn’t even wanted to go out tonight. He was barely leaving the museum when his phone rang, the caller ID reading Kuroo’s phone number, and he’d immediately rejected the call. However, not even two seconds later he received a text with the simple words: “We have freckles with us already so you might as well just come over now instead of fighting it.” So he did. And that familiar annoyance and quick temper has returned, only fueled by the loud music bumping in the over-crowded club that Bokuto and Kuroo dragged his omega to-

There it is again. Yamaguchi isn’t his. He isn’t Kei’s, and he knows this. Even still, in his head, he calls him that. He doesn’t know when he that started, just that he never stopped, and he doesn’t see any harm in it; after all, anyone who’s spent more than a few hours with them can clearly see Kei’s laid his claim on Yamaguchi even if he hasn’t actually marked him. Or even tried to court him. His influence is all over, however, from the clothes Kei buys him just so he can scent them before he gifts them to the fading hickeys Yamaguchi asks Kei to give him before they go out to deter alphas from hitting on him when they’re clubbing. 

Even still, those only seem to work if the other person knows them, and isn’t some stranger in the club. To strangers, Kei’s scent and the hickeys he peppers on Yamaguchi’s neck are just hints of a promiscuous omega, a tease who gets busy with more than one person in one night- and they tend to get angry when their advances are rejected by a “slut.” 

Kei doesn’t know when he lost Yamaguchi, just that he’s been increasingly more annoyed by his other friends as they progressively get drunker. And so he does what he usually does when he gets fed up with them: goes to find Yamaguchi so he can leave. It takes a long moment to find him, and when he does, he doesn’t like what he finds. 

He can’t hear over the music and the loud conversations surrounding them, but he can see the snarl on the alpha’s face as he leans far too close to Yamaguchi. The omega -his omega- is leaning as far away as he can, but his back is pressed against the wall with nowhere else to go. It takes three seconds to get from the bar to where they are, just in time for the alpha to reach a hand up Yamaguchi’s skirt and promptly get punched in the jaw by Yamaguchi. Immediately the area around them clears around them so Kei can step in between them. 

“You bit-” 

The alpha goes to punch back, but freezes when he sees Kei standing there. “You’d really punch an omega that just hit you so hard you had those cartoon birds flying around your head? That’s kind of pathetic, man.” 

“Who are you, this little slut’s babysitter? Why don’t you tell ‘im to-” 

“I’d stop right there, or I’ll let him loose on you again. Do you want an omega to knock you out?” 

The alpha growls, but he backs off, flicking them off once more before he disappears into the crowd. Kei turns to Yamaguchi as the people immediately around them dissolve back into the club mentality, ignoring the two as soon as the drama is over. When Kei turns around, Yamaguchi’s fist is still clenched, skirt ridden up just the slightest, and he’s shaking. 

“Yamaguchi, let’s go.” 

“What? I- I’m fine, Tsukki. Let’s just go find the others,” 

“I just left them, I was coming to find you anyway.” 

“But I wanna stay,” 

“And get groped by some stranger again? I don’t think so.” Kei says. 

Yamaguchi huffs. “Come on Tsukki, please? I barely have a buzz, I-” 

“And if you get any drunker, you’re gonna get taken advantage of by some random alpha.” 

“And what if I want that?” 

“I- What?” Kei’s eyes narrow and he glares at Yamaguchi, stepping closer to him. “You’re okay with just anyone taking you home? What if one of them marks you? What if they get you pregnant?” 

Yamaguchi crosses his arms and glares right back. “And what if they do? It’s not like you are.” 

Something in Kei snaps then, and he growls, taking Yamaguchi by the wrist and pulling him against his chest. He isn’t one to use his alpha status above an omega, but he can’t help himself as he commands Yamaguchi with his alpha voice, “We’re leaving. Now.” 

Yamaguchi doesn’t protest as Kei drags him out of the club, and Kei ignores the whoops and hollers from a drunk Bokuto and Kuroo, both of whom are trying to reign in a drunk Hinata before he climbs onto the bar and shows all of Sendai the dance moves he’d learned in Brazil. Once out of the club, his senses sharpen and he feels a bit better, but anger still boils in his chest as he drags Yamaguchi down the street and to the closest train station. After swiping their metro cards he takes Yamaguchi and pins him against the wall, kissing him roughly while they wait for their train. 

“Is this what you wanted? Attention from me? Is that why you wore this little number and went off and almost got yourself groped in the club by whoever you could get to touch you so I would get jealous?” 

“M- Maybe,” Yamaguchi murmurs against Kei’s lips, gasping when Kei’s knee slips between his thighs, arms hiding him from the rest of the underground station. “I was tired of your fucking pretending like there isn’t something between us, so I figured I’d give you a push. Is that so wrong?” 

“It is when my omega is backed into a corner with a hand up his skirt by someone that’s not me.” 

“So you admit I’m yours?” 

“Of fucking course you are! When have you ever not been?” Yamaguchi swallows thickly, his wide-eyed gaze looking at Kei like he hung the goddamn moon, and Kei growls. “As soon as we get back to my place I’m fucking you so goddamn hard and you’re getting a bond mark right,” he nips at the junction of Yamaguchi’s neck and shoulder, “There. Understand? No one is going to mistake you for single after this.” 

“Y- Yes, alpha.” 

“That’s what I like to hear.” They continue to kiss while they wait, and once again when their train arrives. Once they reach their stop, Kei’s hand once again finds Yamaguchi’s wrist and he pulls him along, feeling a little guilty when he sees it’s bright red from being grabbed so roughly; it’ll definitely bruise before the night is over. He doesn’t have time to feel guilty, however, because Yamaguchi’s hand slips into Kei’s front pants pocket and pulls his keys out of it, unlocking his apartment and pushing him inside. Kei grins, pulling Yamaguchi by his collar into a kiss as they scramble to take their shoes off while still kissing. “Feisty now, huh?” 

“Just impatient. I’ve been waiting for this moment since we were seventeen.” 

Kei groans against Tadashi’s lips. “You mean I could’ve been fucking you since second year? That was six years ago,” 

“I didn’t think you liked me back until, like, six months ago Tsukki! And I thought you would make the first move, since you’re an alpha.” 

“You know I’m just as stubborn as you, did you really think I’d give up my pride and confess?” 

“Hey, it’s not my fault you’re stupid. Now are you going to claim me or not?” 

“You don’t have to ask twice,” Now out of their shoes, Kei lifts Tadashi and carries him down the hall to his bedroom. He has half the mind to fuck him right on the floor in the genkan, but he at least has the sense to make sure Yamaguchi is comfortable while he fucks his brains out. Once in his bedroom, he drops Yamaguchi on the bed, his hands fumbling with the buttons of his shirt. Yamaguchi pulls away just the slightest to pull his top off, wiggling out of his skirt while Kei shucks off his own shirt and begins undoing the buttons on his slacks. He growls when he sees Yamaguchi’s nearly naked form underneath him, the light pink boxer briefs damp and tenting his dick. “Fuck, you’re so gorgeous, you know that?” 

“That’s coming from you? You’re a literal god, Kei.” 

Something about Yamaguchi calling him by his given name screams to the primal side inside of Kei. Nipping at his lips, Kei’s hands find Yamaguchi’s hips and pulls them flush against his. “You’re so fucking hot. I’m going to make sure the only think you can say is my name.” 

“Yes, please.” Yamaguchi whispers. Resisting the urge to rip Yamaguchi’s underwear, he slides it off as quickly and as gracelessly as possible, losing his cool immediately when the scent of slick unhidden by clothing hits his nose. He pulls away to get a good look at Yamaguchi totally naked, now, and he growls. 

“You’re dripping. Have you been slicked up the whole way home, or did I just work you up in the few minutes we’ve been back home?” 

“Th- The first option,” 

"Well I’m going to treat you so good, don’t you worry. I know I could probably slip right in with how wet you are right now, but I’m gonna prep you, okay?” 

“Okay.” 

One of Kei’s hands spreads Yamaguchi’s thighs, the other moving to tease at his rim. Yamaguchi whines, his knees trying to close, and Kei nips at his jaw, keeping his legs spread with a firm grip. “Don’t hide yourself. I’m going to be seeing a while lot of you, so there’s no point in being shy.” 

Whimpering, Tadashi nods slowly, and relaxes somewhat as Kei slips two fingers inside of his hole. Kei’s fingers are long and slim, and slip inside easily, slick coating them immediately. He probably didn’t even need to prepare the omega, because he’s reacting so well to Kei’s touch and opening up with little prodding; his little cock sits rock-hard and dripping, untouched, and Kei’s own cock twitches at the sight of the man in front of him. Yamaguchi gasps when Kei’s fingers shift inside of him and Kei grins, dragging his fingers over the same spot. He revels in the way Yamaguchi moans and whines, rolling his hips to get more stimulation. 

“Fuck, Kei...N- Need you, now. Please. Please,” 

Suddenly Kei’s confidence wanes and he hesitates, looking down at Yamaguchi. “I don’t want to hurt you, Tadashi.” 

Yamaguchi groans. “I can take it, Tsukki. Come on, fuck me.” 

“Right. Right, I’m going to fuck you and I’m going to claim you. Got it?” 

“Got it.” 

Kei slides his fingers out of Yamaguchi’s hole, positioning his member and pushing inside. As soon as the tip slips in he groans, pleasure overtaking him as he bottoms out with one quick thrust that brings out a loud cry from the omega underneath him. He growls, connecting their lips once more, as he fucks into Yamaguchi roughly. His hands wander Yamaguchi’s body, the omega reacting to his touch so well, his back arching off the bed. Kei sucks in every little sound, every little tightening around his cock, quickly losing control of himself. 

“Fuck, Tadashi...You’re mine. I’m not going to let anyone touch you ever again, you’re mine and only mine, you understand?” 

Yamaguchi keens, a shiver running down his spine, and nods. His hands, tangled in Kei’s hair, grips tighter with every thrust. 

“If any other alpha even looks at you after this, I’m gonna fucking kill him.” 

“Possessive of me already? You haven’t even- hn, you haven’t even marked me yet.” 

“If you want to rush me, Tadashi, I can gladly make you cum faster, but I quite like this pace more,” Kei growls, thrusting harder, and he hears Yamaguchi’s breath hitch. 

“F- Fuck, please, Kei, faster. Please. ‘m so close, so ready, plea-” Yamaguchi gasps, his eyes rolling to the back of his head, and Kei grins. He nips at Yamaguchi’s neck, right where he’s preparing to mark him, and reaches a hand down to stroke Yamaguchi’s dick. Yamaguchi reacts to the touch with a shout that will more than likely get Kei a noise complaint from his neighbors, but he doesn’t care one bit. Kei’s own orgasm builds closer and closer as he continues fucking into Yamaguchi ruthlessly, and he knows Yamaguchi is close by how much he starts to tighten around his cock. 

“Tadashi...Tadashi, I’m gonna cum. I’m gonna fill you up so good, baby,” He pants, “You’re going to be full of my pups soon enough. I’m going to claim you and get you pregnant as soon as possible, so everyone knows you’re mine. You’re mine, hear that? Mine.” 

“Fuck, Kei..! Please, please, ‘m coming, claim me alpha, ple- agh!” 

Kei wastes no time in biting down on the junction of Yamaguchi’s neck and shoulder, claiming the omega as he comes. As his teeth sink into flesh, Kei’s own orgasm spills inside of Yamaguchi and he thrusts one final time as his knot swells and locks them together. An indescribable pleasure washes over him as he feels the mating bond form between them. Once they’ve both finished, Kei collapses on top of Yamaguchi, both of them panting breathlessly. 

In the morning, Kei will likely be embarrassed about letting his inner alpha out like this, but for now, he allows himself to feel the bliss of a fresh bond with the man he loves. 

I head cannon Tsukishima is absolutely a horn dog, it’s always the reserved, quiet ones who have the most unsuspecting libido (I say as a quiet, reserved woman with a huge sex drive) like you’d think he’s completely uninterested in sex but no no, If only everyone knew what was in his mind. He gives me huge closet pervert vibes. taking peeks up your skirt when you bend over or sneaking glances at your cleavage when it’s summer. Totally says things in his head in reply to you instead of what actually comes from his lips.

“tsukishima can you help me with these balls?”

hm no but you can help me with mine “sure”

when you finally get that far with him you’re sure you’re delusional. Expecting a soft, relatively quiet and vanilla guy but then you’re bent over his bed with your underwear shoved in your mouth and him pounding into you from behind, spilling filthy words into your ear. You see his true nature.

Sorry Tsukki
