Chapter Text

“I just think he’d be more confident if he had some experience,” Mirio tells you one night, thick arms wrapped around your waist as you relax in your bed together. “I can’t ask Nejire, it’d be too weird for him. Will you think about it?” You’re pretty sure this plan isn’t going to work, but eventually you agree to help.

And that’s how you find yourself in Tamaki’s room a few days later, wearing Mirio’s hoodie like a dress as the three of you work through some particularly sadistic math homework. You’ve been waiting for the right moment to spring your trap, and when Tamaki sets down his book for a quick break your boyfriend gives you a smile of encouragement to go for it. With a last deep breath you stretch and move to sit next to the other boy.

“Hey, Tamaki? Can we talk?” His expression is tired but curious and you begin. “I, um, heard about what happened the other day with Yuki from the other class and-”

He groans in frustration. “You mean how she tried to buy me lunch and I panicked? I didn’t need a reminder.”

“That’s not it,” Mirio says, grinning brightly from his seat on the floor. “We want to help you get some confidence for next time.”

He narrows his eyes with suspicion. “How?”

You begin to explain but you’re cut off by Mirio gesturing happily to you. “Practice with her!”

Tamaki gawks at you both in disbelief.  “Are you...wait...what?” He looks frantically between the two of you, mouth agape. “You can’t just offer me your girlfriend, Mirio!”

“I don’t mind,” you point out, and he jumps when you touch his shoulder. You rub soothing lines down his arm until you feel him relax just a fraction. “We don’t have to do anything if you’re uncomfortable,” you flash him a reassuring smile. “But if you want, we can just have some fun. No pressure, or weirdness tomorrow or anything. Okay?”

Tamaki sits there for a solid minute, debating his options. Mirio’s smirk begins to falter a bit, but you continue stroking his arm gently as you wait for an answer. “Okay,” he agrees finally, shyly lifting his head to meet your eye.

“Alright!” Mirio cheers, and then a thought occurs to him. “Oh. Should I leave and give you guys some privacy?”

“No!” both of you answer immediately. You two get along well enough on your own, but you know he’s the glue holding this operation together. It wouldn’t feel right to do this without him. Mirio’s smile is beaming and he moves to sit in the chair at the desk where he can have a better view.

You run a hand through Tamaki’s hair and he focuses on you. “That feels...good.” He’s already blushing, unsure of how to even proceed and you accept the fact that you’re going to have to take the lead here. You move slowly, doing your best not to scare him off.

“Can I kiss you?” His eyes widen and he swallows nervously before nodding. You reach up to touch his cheek, angling his face towards you as you sit up straighter to meet him. You keep it innocent and short, pulling away before he has a chance to feel overwhelmed. You’re pleased to see him lean forward instinctively for more and you indulge him, holding your second kiss long enough you need to break for air. “How’s that?”

He murmurs something positive that you don’t quite catch, but it’s adorable how much he’s blushing. “Where do I put my hands?” He looks lost, flexing his fingers awkwardly in front of you. You fight back a laugh, scooting closer on the bed and guiding him to hold your waist.

“How about here?” Tamaki nods silently and you go in for another kiss. This time you stroke your hand over his back, feeling his muscles tense but he doesn’t shy away from you. You work him like this for a few minutes, carefully coaxing him out of his shell until he’s actively participating. You press forward, brushing your tongue over his lips and he freezes for a moment before opening his mouth to your advances. He’s a little clumsy but it’s cute, and when he lets out a little moan around your tongue you can’t help but grin. Ever so slowly you encourage him, and eventually he’s the one sliding into your mouth. You can still taste the takoyaki he ate earlier, but it’s not unpleasant.

Tamaki’s grip on you tightens and you groan, but a sound nearby surprises you and the two of you separate. Mirio is watching the scene with undisguised interest. You’ve been worried that he might be a little jealous or upset once you went into action, but the look on his face is nothing but joyful excitement. “Don’t stop,” he commands with a wave of his hand. “This is really good.”

With that weight lifted off you, you resume your attack on Tamaki’s body. You leave one last, deep kiss on his lips before trailing along his jaw to brush over his neck. He’s sensitive there, you realize as his head tilts to give you better access and he whimpers as you suck lightly at his pulse. “You’re so cute,” you coo, amazed that he can somehow blush even more. This is new for you, being the dominant one, and you can see why Mirio takes control so often. It’s a rush of confidence to have someone so needy for you, being wanted and trusted so much to have them vulnerable to every touch and kiss and word you give them.

You run your hands over his chest, feeling his ever-present anxiety like a current running beneath his skin. “It’s alright,” you soothe as his heart rate shoots through the roof. You return to his comfort zone, pressing your lips to his again until he calms down. He practically purrs when you move to draw another path of kisses down his throat, shifting the neck of his shirt to end at his collarbone. “I want to take this off, if you’re okay with it.” He gives the smallest nod and you smile, making sure to give him the chance to change his mind as you pull it off his torso. It occurs to you that you’ve never seen him like this before, and you find yourself silently making some comparisons.

Your boyfriend is practically a solid wall of pure strength, thick biceps and broad chest clearly defined in the tee shirt he’s wearing now. Tamaki in contrast is all lean muscle, toned but slim. You watch his eyes flick over to Mirio and you can tell he’s very aware of the difference. “Sorry,” he says quietly. “I know i’m not...”

You shake your head and reach up to ruffle his hair. “Hey, don’t do that. You’re really good looking.” His expression says the he doesn’t quite believe you, but he doesn’t argue as you resume your attention. Your fingers run over his chest, relishing the little gasps he makes when you tease his nipples. “So cute,” you repeat, bringing him in for another kiss. You feel his hands move slowly, one cupping your cheek to deepen the kiss. The other finds your thigh, fingers brushing over your skin lightly with unsure touches. “That tickles,” you choke back a giggle. He pauses and you’re quick to reassure him. “You don’t have to stop, I like it.” He’s clearly still nervous about this whole situation and you’re happy to offer encouragement with every move. You never stop the kisses as your hands roam over his body, allowing him to grow comfortable with the feel of you on his bare skin. Tamaki cries out when you nip at his collarbone, leaving a faint red mark that will fade soon enough. “Too much?” you ask, pleased when he shakes his head. You’re starting to feel warm yourself, familiar heat flickering in your belly as he carefully pushes the hem of your hoodie up a bit to touch more of your thighs.

You busy yourself with stroking his chest, gradually petting lower down his abs until you reach the zipper of his jeans and he freezes solid as if paralyzed. You withdraw immediately, lifting your palms in surrender and making sure there’s no trace of disappointment in your voice. “That’s fine. We can stop here if you want.” You keep your expression friendly, and out of the corner of your eye you see Mirio nod in agreement. He’s probably even happier than you are that you got this far.

Tamaki stays silent for a minute, glancing between you both while he collects his thoughts. “I don’t know what I’m doing,” he points out, staring at the wall. “I don’t want to screw it up.”

“You won’t,” you hold his cheek fondly. “This is new for us, it’s okay if it takes some trial and error.”

Mirio raises his hand. “That’s right! I’ve gone in the wrong hole before!” You grimace at the memory; he didn’t need to offer that example.

Tamaki can’t help his snort of laughter at the comment. You can still sense his anxiety as he looks back to you. “What do I do?”

You reach for his pants again. “Why don’t you start by taking these off?” You know it’s a big step, and you give him plenty of time to decide before he silently stands up and clumsily works at his fly. You unconsciously lick your lips at the sight of the obvious tent he’s sporting. You’re so distracted by the boy in front of you, you don’t notice the movement at your side until hands snake around your waist and down to the bottom of your shirt.

“It’s only fair if you take this off too,” Mirio points out. You can feel his smirk against your neck as he yanks it over your head without a second thought. Tamaki fumbles, pants halfway off, looking very much like he’s just been hit by a truck. It suddenly makes sense why you’ve been wearing the largest hoodie Mirio owns, even though it fits you like a tent with impractically long sleeves and a hem that almost hit your knees. It wasn’t a fashion choice; it was to hide the fact that you were completely naked underneath. The two of you had planned this attack on him in advance.

“Tamaki, breathe!” He’s starting to turn blue from lack of oxygen before his brain resets and he inhales sharply. He’s staring at you unblinkingly, eyes roving from your face to your breasts and between your thighs. You’re not sure if he’s going to faint or run straight out the door, but you’re starting to feel self-conscious under his unbreakable focus. You cross your arms under your chest, fighting the urge to cover yourself. He swallows several times to clear his throat and finally break the increasingly uncomfortable silence in the room.

“...You’re pretty.”

The relief is palpable as it sweeps through his dorm. “Thanks.” Of course Mirio never misses a chance to compliment your looks, but it’s nice to have a second opinion. He seems to have forgotten his task, jeans hanging limply from his hips and you take it upon yourself to finally shove them down, taking his hand for support so he can kick them off. You’ll let him keep his underwear for now, you’re sure he won’t want them for long.

You position Tamaki to sit at the top of his bed against the pillows, Mirio more than happy to help you climb onto his lap. Your boyfriend automatically reaches for your chest and you slap his hand away. “Let him do it,” you scold, watching him pout as he moves back. You turn your attention back to Tamaki, recognizing the apprehensive look on his face as you guide his hands back to your waist. “We’ll take it slow, okay?” He nods and your own hands find his shoulders for balance as your tongue slips back into his mouth, coaxing him into the familiar rhythm you’d had earlier.

The kissing is nice, but you can tell from the way his eyes keep falling to your breasts that his interests have moved beyond that. With a smile your fingers wrap around the hand at your side to bring it higher. “Here, is this what you want?” He responds with a shaky groan, squeezing your breast and giving your nipple a gentle pinch. “Mmm, that feels good.”

You let him tease you like this for awhile, giving him the chance to figure out your body and what he likes of it. You’re not shy about how much you enjoy having your chest played with, and the positive reinforcement is definitely helping to ease his nerves. You can’t help it; his hands are ghosting so lightly over your skin, it’s starting to drive you crazy. You squirm in his lap, pressing closer to his body and the contact forces an idea out of his mouth before he can stop himself.

“Hey,” he can’t quite meet your eyes when he speaks. “Can...can I use my mouth? On you, here?”

You blink. It’s the first actual request he’s made all night, and you’re surprised that he even voiced it. You recover in only a second though, reminding yourself that tonight is all for him. “Sure, whatever you want.” You reposition yourself, straightening your back to bring your chest up to his eye level. Tamaki pauses again, unsure of how to continue. “Come here,” you urge, hand on his neck guiding him down to his target. Very slowly, as if he’s still afraid you’ll change your mind, he captures one of your nipples in his mouth, tongue barely brushing against your sensitive peak. Your breath stutters;  it’s so slight and careful and different from what you’re familiar with, you weren’t prepared for it to feel so good. “Oh, wow,” your mouth feels dry and he’s gauging your reaction. “Do that again, please.”

You don’t try to hide the sounds you make as Tamaki sucks at your nipples, you can tell he’s enjoying every moan and whimper out of your mouth. His hands gradually move to trail over your body, touch so soft as if he thinks you’re something precious and fragile. Impulsively you rub your fingers over his bulge, interested to know just what awaits you. The whine he lets out is downright sinful, hips bucking into your hand on instinct. He releases your breast, face even redder than before, mumbling the beginning of an apology. You shush him, taking hold of the hand on your hip and leading it between your thighs. His eyes go wide with the realization of just how wet you are. “You don’t have to stop,” you offer, swallowing down the flicker of nerves in your own mind. Mirio had been perfectly clear with his plan that you could back out at any time, and neither of them would be mad if you chickened out at the last minute. But you’ve come so far already tonight, it would be a shame to leave things now. There are still butterflies in your stomach at the thought of what you’re about to do, but you will yourself to relax with a decisive sigh. You know what all three of you want, you only have to ask for it.

“Tamaki, will you fuck me?”

He can’t answer you, gazing at your face with a look that’s not quite panic. It’s something of a good sign, at least. His eyes dart over to Mirio, sitting somewhere behind you that you can’t see but you’re sure he’s grinning like a madman and offering a thumbs up. It’s a big step, and you don’t pressure him as he takes a painfully long time to make the decision. Finally, dragging his attention from the floor to look back up at you both, he give a small nod. “Alright.”

You kiss him again, deep and slow, letting him know you have no intent to rush him. With clumsy fingers he pulls at the underwear, you straddle him wider to allow him enough room to slide them off completely. Suddenly he seems very focused on staring at the wall, away from your face as you look down at your first sight of your prize. You’re not surprised that he’s smaller than Mirio, but you’re far from unhappy. His size seems average, with a nice curve towards his head that promises to be a new experience for you. There’s a drop of precum leaking from the tip and you have to fight the urge to taste him. Maybe you’ll have another chance sometime.

You haven’t spoken in a minute, and his first concern is that you’re disappointed. “I’m not as big as you want-”

“You’re perfect,” you assure him. “You’re gonna feel so good, honey.” Blindly you stick your arm out and then Mirio’s beside you, giving you a nice long kiss of his own. He passes a condom into your waiting palm; it had been your only demand when he’d suggested this idea. Of course you trust Tamaki, and you’ve been on the pill for years now...but you love Mirio, and you want him to be the only one who gets to come inside you. He can’t resist giving you a firm, playful slap on the ass as he returns to his seat at the edge of the bed.

Tamaki stays as still as a statue, watching carefully as you tear open the foil and reach for him. You like it, the little groan at the back of his throat as you hold his cock to roll the thin latex over his skin. You bring his hands back to your hips for support and you give him one last chance to stop. “You sure about this?”

“Y-yeah. I want it.”

You smile at him, spreading yourself open while your other hand lines his dick up with your entrance. You sink down slowly, withdrawing only a bit before coming back down and soon he’s fully sheathed inside your pussy. You stop, allowing him plenty of time to get used to the feeling. A sweet little shiver runs down his spine at the sensation of being buried inside you, the moan leaving his mouth without a thought. Oh, you like this. Even after a few moments there’s still a tremble in his touch as he squeezes you, but you get the message. Your rhythm is easy and gentle, lifting halfway off to slide down to the hilt and rub your pelvis into his. You keep the pace slow and intimate, trying not to overwhelm him yet.

Despite your best efforts, it only takes a few minutes to have him panting hard, the quiet whimpers you earn with each stroke onto his cock spurring you on. You knew his first time wouldn’t be a long one, but you don’t have any excuse for teasing him this way. He’s just so cute like this, eyes closed and blushing to his ears and making those sounds, all for you. You can’t resist leaning forward to suck at his throat, drawing out a red mark that’s beautiful against his pale skin. Your name comes out as a breathless whine and you clench around him, covering his collarbone with open-mouthed kisses up to his lips.

“You’re doing so great,” you purr. Your fingers trail down his arms to link with his, forcing his grip harder on your skin. “Is this what you like? Come on, help me make you feel good.” You nearly come to a stop, compelling him to raise you up and down his length without thinking about it. “Mmm, that’s it. You want more?” You’re aided by his strength as you let him decide your speed, nuzzling into his neck to hide the satisfied smirk you’re wearing. You’d been right, every thrust causes his cock to rub against a sensitive spot you’ve only just discovered, the faster rhythm making you tingle with each pass. “You feel so good, Tamaki,” you groan as your cunt squeezes around him.

“You’re warm,” he gasps, gaze fixed between your thighs. You lean back to give him a better view, doing your best to keep your tempo even and his mouth falls open at the sight of his dick disappearing in and out of your willing body. The scene in front of him, combined with the way you feel and the sounds you make as you bounce on his dick are threatening to send him over the edge already. You weren’t expecting him to have record-setting endurance on his first time, but he shows surprising willpower as he struggles against the uncharacteristic urge to just hold you in place and rut into you until his body gives out.

You can tell he’s close. Already clumsy, his movements grow increasingly erratic as he thrusts harder up into you. There’s something really appealing about taking him like this, and you’re not sure you’ll last much longer either. You let out a ragged breath as you take his hand and guide it down between your bodies. “Touch me here,” you plead, pointing out your clit. “I wanna finish with you. Please, Tamaki?” His fingers are shaking but he obliges, stroking you gently, unaware of how much it’s teasing you. Your cunt clenches tight around him and it’s too much for him; he only gets a few more rapid thrusts before he buries deep inside you, shuddering and gasping as you feel the heat of his cum even through the condom. With your main objective complete you quickly chase your own orgasm, taking over for him and rubbing hard circles into your clit until your own release hits, barely a minute later. Your partner lets out a quiet whine at the feeling of you spasming over his sensitive cock.

You lean forward to rest your forehead against his heaving chest, both of you doing your best to catch your breaths. “That was fun,” you pant out with a laugh. You lift yourself to let his dick slip free, carefully stripping off the used condom to throw away.

“Thank you.” Tamaki’s still blushing as he looks you over, but there’s a small smile you can see he’s trying to hide. The two of you look at each other for a second, neither of you really sure how to proceed. And then you’re suddenly pulled backwards off of his lap to find yourself pressed against a broad, muscular chest. You’re not sure when Mirio’s clothes came off, but you’ve been pretty distracted.

“Babe, that was so hot.” Mirio’s breath is warm in your ear, it makes you shiver. “You looked so good riding Tamaki for me.” He grabs your chin, tilting you into a deep kiss that takes your breath away. You instantly let him take control; you’d enjoyed being the one in charge earlier, but now you’re relishing the thought of being taken care of. He’s already so hard, wasting no time spreading your legs open to slide his bare cock between your folds. He makes sure to nudge your clit with the dripping head; he knows what you like and it earns a nice, breathy moan from you. “God, you’re soaked. You really did love it.” There’s no hint of jealousy in his voice, only pure adoration as his arm tightens around your waist to hold you closer and the other launches an expert attack on your breasts. “Come on, how ‘bout you put it in for me?”

You obey without a second thought, taking hold of his shaft to press the thick tip into your pussy. You’ve hardly begun to slide him in before impatient hips buck forward, impaling you halfway on his dick with a rough grunt. “You’re so wet,” he points out, kissing your shoulder with a grin. “You took so much of me already!”

You struggle to speak as you’re jolted by another deep thrust, feeling his hips against your ass as he bottoms out inside you. “S-slow down, I’m not going anywhere.”

Mirio kneads your chest thoughtfully for a moment. “Nope.” You can feel the smirk against your neck. “You feel too good.”

You whine, pressing your face into his shoulder. The pace he sets is fast and rough, and you’re still sensitive from your time with Tamaki. “Mirio, pleeeease.”

He groans into your skin, voice husky with arousal. “Fuck, baby. Come on, you can take it.” He thrusts hard, pulling you flush against his sculpted body and you cry out. Even during sex, it takes a lot to make Mirio talk like that. If he’s this worked up already, you know you’re going to be absolutely worn out tomorrow. You crane your neck to look back at him, cheeks flushed and eyes dark as he watches your breasts jiggle with every move he makes. He looks so good like this, totally losing himself in his desire for you. He gives you that toothy smile you love so much and you have to look away before you snap, cunt milking him for more despite your earlier request.

Something catches your eye near the top of the bed as you shift focus. Tamaki’s recovered, and he’s now fisting his cock slowly while he watches you get fucked within an inch of your life. You squeeze the arm around your waist for attention, and Mirio’s punishing rhythm finally slows down when he notices. You can tell the wheels in his head are turning and a thought occurs to him just as Tamaki looks up and realizes he’s been caught. He opens his mouth to apologize but is quickly cut off from the voice behind you.

“Wanna try with both of us?” The question hangs in the air while you consider it. Your boyfriend demands so much from you on his own, you’re not sure you can handle the two of them together. But, there’s something wickedly appealing about taking on the two strongest people you know, doing your best to satisfy them while they both use your body to their hearts’ content. Who knows when you’ll get this kind of opportunity again?

You lick your lips. “Yeah. Let’s do it.” Immediately Miro’s hands adjust their position on you, pressing on your back to put you on all fours and then grabbing your hips firmly. Tamaki seems unsure, but Mirio gestures excitedly for him to kneel in front of you and it’s hard to argue at the moment.

“Don’t worry, she’ll take good care of you. Her mouth is amazing!” It’s impossible to miss the way you clench around him at the compliment. The boy in front of you swallows again but obediently moves forward, blushing furiously as he looks down at you with the realization that yes, this is happening.

Mirio’s still balls deep inside you, pumping shallowly as you lick a stripe up Tamaki’s dick. You do it a few times to get him used to the feeling of being touched like this, his shuddering gasp encouraging you. You flick your tongue over the slit, collecting the bead of precum he’s leaking; he tastes saltier, and you wonder if it’s a side effect of his quirk. He’s already twitching against your lips and you look up at him to meet his gaze with a spark of mischief in your own. You give him no warning as you open wide, mouth closing around the tip of his cock and slipping halfway down his shaft. His fingers instinctively yank at your hair, moan cracking in his throat like he’s choking on the sound.

You draw back, swirling around him as you move before taking him a bit deeper inside your mouth. You keep your hands firmly planted on the bed for balance, relaxing your jaw to slide more of his throbbing dick between your lips. You bob back and forth on his length until you take him completely, your nose bumping against his pelvis as you pull another needy whimper from him. You can practically feel the tension in his body, he’s trying so hard not to buck into your mouth and you want to see just how long his control can hold out.

You drag your tongue up from the base of his cock to suck lightly on the head and Tamaki can’t help himself. His hand tightens in your hair, shoving you back down to feel your warmth around him again with a groan of pure need. You manage not to gag, pushing back against his grasp to keep him off the back of your throat. “Sorry,” he huffs and you give him your best attempt at a smile. His hips are starting to jerk forward, desperate for more attention after so little time. Behind you, you can feel Mirio beginning to pump into you faster, murmuring something about how pretty you look between them. You redouble your efforts, saliva dripping down your chin as you allow him deeper into your mouth.

Your boyfriend lets out a growl of approval at the sight of you like this, his patience rapidly crumbling and your body is rocked forward by the sudden force. He’s so much stronger than you, you can feel the raw power in the hands on your skin and the smack of his hips as he fucks you nice and hard. There’s no question as to which one of you is in charge here; you’re being shoved repeatedly into Tamaki’s lap and pulled back to meet his thrusts with every stroke. What’s left of your brain scrambles to adapt, clumsily matching his rhythm as you try to breathe around the dick nestled snugly in your throat. It’s hard enough for you to last when he fucks you like this on a normal night, but adding in another person, currently holding your head tightly to his groin and looking at you like you’re some kind of benevolent goddess, is only making that heat inside you flare up more. It feels so good, but you can only offer muffled whines as both of them enjoy your eager body.

You’re vaguely aware that your boys are saying something to each other, but you’re far too distracted by your work to pay attention. You shiver a bit when you feel warm hands come down to grope your breasts and you let your throat squeeze around him. Your mind is shrouded in a fog of sex; it takes far too long to realize that something feels...off about his fingers. You pause momentarily to glance down and nearly choke on his shaft as a single word flashes in your head: Takoyaki.

The tentacles are an unexpected twist but you can’t say you dislike them. They’re flexible and surprisingly soft, it tickles as they grope at your chest. You’re just getting used to it when several of them change tactic to target your nipples directly. Your eyes nearly bulge out of your skull, muted cries dying on your lips as pleasure shoots down your spine. Mirio lets out a breathless laugh at your pussy gripping him like a vise and kneads a handful of your ass. “Oh, wow, she really likes that. Keep it up.” Of course he obeys, appendages squirming over you with even more intensity until you’re on the verge of tears.

You’ve reached your limit. You can’t keep up with them anymore. Tamaki’s tentacles are almost painful in how they tease your sensitive nipples, and Mirio’s pace has you struggling to stay upright on shaky limbs. You’re reduced to whimpering softly around the cock buried in your mouth with every movement, and it’s only a second later that a familiar hand slides between your open legs and strokes your clit. It’s all you need to throw you over the edge and you come, crying out something that might have been their names as you go rigid between them. One of them takes mercy on you and pulls out to give you some much needed air, but that just gives the other the opportunity to drag you fully onto his cock, loving the way your cunt spasms around him. You wail for him, loud and drawn out and it’s beautiful.

You rebound after what seems like ages, jostled back to the present by the man who hasn’t paused for a moment in fucking you. “That was so great, princess. Now help him, just a little bit more.” It takes so much effort, but you manage to focus in front of you and lazily take Tamaki’s dick between your lips again. You swirl your tongue around him with the energy you have left, sucking gently on the tip and gazing up to meet his eyes. He stammers out a warning and you nod as best you can. There’s just a hint of a tired, happy smile on your face and his fist tightens in your hair as his hips buck hard into your mouth one last time. He tastes salty and bitter, but you swallow all of it and lick him clean. He releases your scalp and pulls out slowly, string of milky saliva connecting you for a moment before he collapses back against the headboard.

You’re only allowed a few seconds to enjoy your handiwork before another hard thrust reminds you that you still have a job to do. Without the balance of a third person, there’s nothing stopping Mirio from pounding you into the mattress like a man possessed. You’re no match for all that manic energy, your arms giving out and dropping you onto your elbows. It’s not a big change, but the new angle allows him to rut into you even deeper and you can tell he’s pushing you towards another orgasm. “Too much,” you gasp out. “Mirio, I-I’m gonna come again.”

His touch is gentle as he rubs you back soothingly, a stark contrast to the brutal pace of his hips. “I know, babe. I know. We’re almost done and then you can take a break, okay?” He leans over you, pressing his sweaty chest against your body to leave kisses across your skin. It’s so intimate, you could easily forget that you’re not the only two people in the world right now. His large, calloused fingers come down to tease your clit again and you can hear how pleased he is at the way you clench around his cock one more time. “Tell me you want it,” he chokes out through clenched teeth.

“I...god, please. Fill me up. I want it so much.” The stimulation on your clit becomes overpowering and you hit your climax, words failing you as you moan for him. He’s right there with you, voice so appealingly ragged and breathless as his rhythm finally stutters and his cum floods into you. Your sore cunt twitches around him, milking him for all he’s got and he goes still to allow both of you a chance to recover.

He pulls out slowly, taking time to admire the mess he’s made of you as cum drips down your thighs. He wipes it off with the corner of the bedsheet and then his strong arms are pulling you up into a warm hug and he’s peppering kisses over your face. “I love you so much! I can’t believe you did all that, you’re amazing!” He looks over at Tamaki, who might have already fallen asleep. “We’re really lucky, aren’t we?” There’s a very quiet groan of agreement, the poor boy is exhausted. “Let’s go back to my room,” he offers, and you don’t miss the way his smile slips into something a bit more suggestive. Looks like break time is over for you already.

You nod, leaning over to give Tamaki a kiss on the cheek before standing up on wobbly legs. Mirio hands you the hoodie, groping your breasts as he helps you put it back on before hastily pulling on his pants. You don’t have to look decent, you’re only going down the hall. It’s surprisingly romantic when he picks you up bridal-style to carry you over, still gushing about how great you are.

Back in his room, you’re reminded exactly why your boyfriend is considered the strongest student at UA. He fucks you through three more orgasms before his own stamina wears out at last. You lay in his bed, cuddled into his chest while every inch of you feels boneless and overworked. “Thanks again. I think we helped a lot,” he says casually. You look up at him with tired eyes, his expression is just so innocent and wholesome after everything tonight that you can’t help but laugh.

“Yeah, I hope so.” You stretch out on top of him and yawn, relishing the warmth of his skin against yours. “Grab the blanket. We’re sleeping in tomorrow.”

“What’d you get for #12?”

Tamaki stares at his notebook. “Uh, 118.”

You groan. “Damn, I got 236.”

“Wait, what? I got the square root of 91.” Mirio looks up, his tongue peeking out from his mouth in concentration. Baffled, you reach for his homework and try to figure out where he went so far off track. Tamaki lets out an exasperated sigh and takes it from you, equally stumped at his best friend’s answer. 

It’s been a few weeks since that heated study session, and the three of you sit around Mirio’s room, once again fighting the villain that is your math homework. You’d been a little worried at first, nervous that things might not really go back to normal between you and Tamaki after your night together. It was a welcome surprise that instead, he’s somehow become slightly less awkward around you. You suppose that getting spitroasted in his bed was enough proof for him that you enjoyed hanging out.

On Mirio’s side, your boyfriend has abandoned any sense of restraint for you around him. Tamaki’s already watched the two of you fuck, he argues, so what reason is there to hold back his affection in front of your friend? It’s not surprising when you’re pulled into his lap as soon as your little group decides to take a break from the assignment. Mirio’s thick arm wraps around your waist to hold you flush against his chest and he kisses your cheek, mid-sentence about plans for this weekend. You glance over and notice a blush spreading across Tamaki’s face as he looks down at the floor.

“Sorry, are you uncomfortable with this?” Mirio manages to pull his focus away form your neck and offers an apology of his own. He drags his gaze back up to meet you and shakes his head.

“No, it’s not that. I just…” He struggles to explain, choosing his words carefully. “I guess...I just feel sort of guilty. You did, y’know, that to help me. And I feel like I’m wasting your help because I still freeze up and panic when I try to talk to anyone. And then I start thinking about how you did all the work, and I didn’t really do anything. And I don’t really know how to do anything that would feel good for someone. And they wouldn’t want me to anyway, because they know that I don’t know what I’m doing. And-”

“Tamaki.” You slip off of Mirio and reach for your friend, pulling him down to sit at your other side on the bed. You give his hand a reassuring squeeze. “It’s okay. Things don’t have to be perfect with someone right away. You’ll learn more about what they like the longer you’re with them, and it’s not a big deal if you make some mistakes along the way.”

Mirio points at his face. “That’s right! She accidentally kicked me in the jaw last week!” To his credit, Tamaki tries his best not to laugh at your misfortune but fails. “It was kinda hot, actually…” your boyfriend thinks out loud.

“Anyways,” you retake control of the conversation before he can derail it further. “It’s totally fine not to know everything instantly.”

He nods and peeks up at you through his bangs. “I get that, but I still wish I knew what I was doing.” You smile at him; it’s honestly flattering that he’s willing to talk to you about his worries, and all you want is to help him. You ruffle his hair, and the way he leans in to your touch is downright heartwarming.

Mirio’s been surprisingly quiet as he’s listened to his closest friend’s turmoil, deep in thought about how to solve this problem. Finally the lightbulb goes off in his mind and he grins, whispering a suggestion in your ear. “Is that okay?” He gives you a kiss on the cheek, eyes bright with mischief while he waits for your response. You feel your face heat up; you really do love him more than anyone, but his idea is too appealing to turn down. Butterflies rising in your stomach, you slowly nod and offer him a sneaky little smile of your own.

“Tamaki,” you clear your throat and he looks up at you nervously. “If you’d like, it might be a good idea to-”

“Practice with her again!” Mirio interrupts, practically bouncing in place. 

The poor boy goes bright red and swallows the lump in his throat. “You’re really okay with that?” His eyes dart between the two of you. “Both of you? I mean, you’re not jealous or anything? It’s not exactly a normal thing…”

Mirio laughs and throws an arm around you. “Why would I be? It’s not like she’s cheating or doing it behind my back. Besides, I know you both had fun last time, and I liked watching you together.”

You rest your head against his shoulder. “It’s his idea, but you know I wouldn’t do it if I didn’t want to.”

He’s a lot quicker to make his decision this time around. “What do you mean by practice?”

Your shirt is already coming off, the answer muffled to you by the movement of fabric. “Just play with her for awhile and see what she likes. It’s not a real date, so you don’t have to be nervous about it. I can help too, if you want.” 

“Please help,” he almost pleads. “What am I supposed to do?”

You squeeze his hand again, leaning over to press your lips to his. “Let’s start with this, okay?” He lets out a shaky sigh, sitting there for a few seconds while you kiss him before he works up the courage to kiss you back. You slip your tongue into his mouth and he groans around you, blushing to the tips of his ears. “You’re too cute,” you coo when you separate for air.

On your other side, a hand slips past the hem of your skirt to brush over your thigh. Mirio’s not content to sit on the sidelines this time, and there’s a playful smirk splashed across his face. He pulls you in for a kiss of his own and flashes that brilliant smile. “You’re the best, baby. We’re gonna take good care of you, aren’t we?”

“Y-yeah,” Tamaki stammers. He’s a little clumsy as he strokes your other thigh and bumps against your nose as he moves back in for your mouth. “Sorry, I-” you tilt your head for a better angle and cut him off. It takes a few minutes for him to get used to it all before he takes the lead, his hand gentle on your chin to guide you how he wants. It’s a rare treat to have him take control and you rub your thighs together out of instinct.

There’s movement against your back, Mirio’s always-cheerful voice paired with it. “Get her other strap, will you?” You’re expecting it when your bra is pulled off, your chest exposed to the warm air of the room and multiple hands are immediately trailing over your naked skin. Mirio doesn’t waste any time in groping at your breast, fingers circling your nipple with familiar confidence. Tamaki is more hesitant, following Mirio’s example with unsteady touches that only tease your appetite for more. The contrast between their attention, entirely focused on pleasing you, sends tingles down your spine and you find yourself squirming before too long. “Tell us how much you like this,” you hear in your ear and you stumble over your words before you manage to obey.

“You both make me feel so good, I love it.” You arch your back to push your chest forward for them and you aren’t disappointed. They’re both covering your skin with eager hands and lips, and it’s a surprise when Tamaki takes the initiative and moves down your body. You can’t help your gasp when his tongue grazes along your stiff nipple, and he glances up at your for permission before drawing it into his mouth and you groan out loud.

Mirio’s eyes are bright with joy. “See? You’re doing great.” You only need to give him a look to get your point across before he joins in and takes the other for himself. You’re used to him paying plenty of attention to your chest, but having both of your breasts sucked on like this has you panting for them in no time at all. Your fingers tangle in the sheets as they lick and tease at your sensitive nipples, moaning openly and squirming between their stronger bodies. “You always sound so cute, babe. Love you.”

“Love you too,” you murmur and run a hand through his hair. You sit back and let them have their fun with you, aware that your panties are growing more damp as they work. You’re being covered with kisses while you feel their hands drift lower, tickling over your ribs and grazing down your stomach. Your thighs flex at the cool air as Mirio tugs the front of your skirt up and tucks it into the waistband out of the way. His fingers stroke over your underwear and he smiles at the clear proof of how much you’re enjoying this.

He motions for Tamaki, who’s still cautiously tracing around your navel. “Come here, look how good you did.” He pulls your panties aside to show off your pussy, both of them staring at you with such obvious interest it makes your face burn. 

“She’s...she’s really pretty,” the other boy mumbles, glancing away shyly. Mirio pulls his hand between your legs to feel you, wet and ready to be touched and his eyes widen. “What now?”

“Use your fingers,” you suggest, distracted by your boyfriend’s attention returning to your neck and chest. His touch ghosts so lightly over your skin it makes you shudder, and when it brushes over your clit you have to fight to keep your legs from clamping shut around his hand. “Do that again,” you ask, cutting him off before he can worry that he’s messed up. You can sense his confidence slowly growing as he obeys, rubbing along your folds and over your clit until he works up the nerve to press a finger into your cunt. “Please, Tamaki…” you whine, and he pushes his tongue back into your mouth before his brain can discourage him.

Mirio turns his head to get a better view of your body. “You look so hot like this, we’re so lucky for you.” He pinches your nipple and you groan, jolting out of the daze you’ve slipped into. “Who’s making you feel this good?”

“Tamaki,” you pant. “You and Tamaki.”

“Fuck.” No matter how long you’ve been with Mirio, hearing him talk like that always makes you feel like there’s liquid fire in your veins. He reaches for your smaller hand and brings it to his lap, where you can feel the heavy erection throbbing under his clothes. You don’t need instructions to know what he wants and after too much fumbling, you manage to get his zipper open and palm him through his underwear. You have enough sense to do the same on your other side, and you’re rewarded with a choked whimper as you grope Tamaki as well. He takes the encouragement and slides a second finger into you, rubbing them along your dripping pussy and shifting his movements to follow every little sound you make.

“Is this okay?”

“Ahh. Honey, it-it’s better than okay. I can take more.”

He obeys, a third finger slipping inside and your muscles clench around him. “Hey, do your hand like this.” Mirio demonstrates for him, twisting his own fingers to illustrate the point. “You wanna feel for a spot that-”

You see stars. “Shit! Tamaki, right there!”

“Wow, you found it faster than I did!” There’s never an ounce of bitterness in his voice, only happiness. “That’s it, just keep doing that and she’ll go crazy.” You bite down on your lip to stay quiet, grinding yourself against Tamaki’s hand. Mirio reaches across your body to tease your clit, and you snap in an instant. You’re not sure whose hand claps over your mouth to keep you from disturbing the entire floor, far too preoccupied by your orgasm to care. You come down gradually, breathing hard like you just ran a marathon; you’re being kissed and touched, showered with praise and compliments. With clumsy hands you give both their cocks a few half-hearted squeezes and notice how hard they’ve gotten for you. Tamaki slowly withdraws his fingers and you shoot him a hazy smile. “Believe me, you’ve got nothing to worry about.”

You’d think he’d be in a better mood after that, but you can tell he’s still holding back something as he rubs his messy fingers together. Your curiosity is piqued when he leans over you to whisper something in his friend’s ear, glancing at you cautiously. Mirio laughs and gives him a supportive pat on the shoulder. “Just ask her, she’ll love it.”

He clears his throat and hunts for the right words. “Do you want--I mean, can I...could I eat--wait, not like eat eat. Maybe I could give you--um…” He trails off exasperated and red as a tomato, but you figure out his point.

“You want to eat me out?”

He nods, embarrassed at his own request. “You’re so sweet, let’s do it.” You’re slipping out of your skirt and panties before strong arms on your other side move you. You end up sprawled across the bed, head in Mirio’s lap with his bulge conveniently next to your face. You can’t take him in your mouth from this angle, but you’re still able to run your tongue over his dick once you tug down his underwear to free him.

Tamaki positions himself between your legs and spreads you so carefully, your cunt still too sensitive from their earlier work and you whine for him. He takes a deep breath to build his courage, then leans in for a long lick up your pussy to your clit. He can feel how well you respond to that and does it again, repeating himself until you’re squirming on the bed long before he’s had his fill. “Wiggle your tongue around inside,” Mirio hints to him, poking you in the cheek for more. You get the picture and open your mouth wider, leaving a wet stripe of your saliva along his shaft. The three of you work together and the small room soon develops into an assortment of obscene sounds from all of you.

Fingers brush against your clit and your hips rut up instinctively towards him. You moan loudly from your spot between them and he pulls away to take in the sight of you, sweaty and weak from his attention. “She’s squeezing around me so much.”

“Oh, yeah. She never lasts long with oral. You’re gonna make her come soon.”

You have no idea how badly he wants that. Your body takes his fingers even more easily now as he pushes them back into you and sucks lightly on your clit. “Tamaki, fuck!” You squeal, abandoning the dick in front of you to yank at his hair. You keep him pinned to you through your climax, coating his mouth and chin with your dripping pussy. You flop back onto the mattress without a care in the world, shifting your neck to finally take Mirio’s throbbing dick in your mouth. He really loved watching that, precum leaking from his tip and you make a show of swiping your tongue over it. You give your poor body a chance to recover as you suck him off, letting him guide your head further into his lap so he can finish deeper in your throat. You swallow everything he gives you and share a pleased smile between yourselves.

You prop yourself up on your elbows and see Tamaki, sitting there awkwardly and watching the two of you with an painfully obvious tent in his boxers. “Oh, sorry! We didn’t get you yet!”

“It’s fine, you don’t have to-”

“Do you wanna have sex again?”

He sputters. “You...wait, really?” He bites his lip for a second before shaking his head. “I don’t, um, I don’t have any condoms.”

“That’s alright,” you look up at your boyfriend expectantly. “Didn’t you get a pack of them?”

He can only give you a sheepish laugh. “I used them all up trying to make balloon animals last week. They didn’t work out.”

“Mirio, no.” This is the man you’ve decided to love, you think to yourself. Your eyes meet and he shrugs, completely unconcerned. It’s your choice, you can practically hear his warm voice in your head. You reach a hand out for Tamaki. “We don’t really need one, if you’re okay without it. If Mirio hasn’t beaten my birth control after all this time; you’ll be fine.”

He gives it a minute of thought and then starts yanking at his own clothes. “You’re sure this is alright?” You bring him down on top of you, spreading your legs apart for him to settle between them. You can feel his cock pulsing against your thigh and reach for it. He jumps in your grasp and his hips jerk forward, bumping uselessly outside of your pussy. You giggle quietly at his eagerness and guide him into position instead. He slowly pushes himself inside and you pull him in for a deep kiss to cover his moan.

Tamaki moves gently as he thrusts his dick into you, whimpering by the time he’s bottomed out and feels you fully wrapped around him. “You f-feel...you feel good,” he stammers, and when you turn your head to drag your tongue over the point of his ear he whines sweetly and bites his lip to keep some semblance of control. “Wanna make you feel good too,” he admits and your heart melts.

You grab onto his hips to pull him further to you. “Here, you can go a little harder.” He nods, more than willing to follow every instruction you give him. You feel a different, larger hand on your head and you glance up toward the top of the bed. Mirio’s sitting there petting at your hair, looking at you with so much affection that you can’t believe you ever got this lucky. Tamaki buries his face in your neck, trailing sloppy kisses across your throat as he fucks into you. 

What he lacks in confidence he makes up for with devotion, paying attention to every little noise and movement you make. You don’t even have to finish a request for him to move faster, or touch you, or let you kiss him; he obeys your every word, entirely determined to please you. You lie back and let him rut himself into you, cunt clenching down on him when he brushes against a sensitive spot inside. His name comes out as a shaky groan from you and your thighs squeeze around him to hold him flush against your own sweating body. You’re not sure when he frees a hand to grab yours, but you weave your fingers with his and he can’t look away from you. He’d never have the nerve to say it usually, but you can hear him murmuring under his breath, ragged voice panting out about how you’re beautiful, and perfect, and you feel too good-too good-too good-

“Tamakiiii,” you moan for him, dragging your unoccupied hand down your body to rub your clit. You’re already on the edge from his attention, and it’s the last bit you need to push yourself into another climax, clamping tight around his dick in a way that sends electricity shooting up his spine. You really have no idea how fucking dangerous you are, do you?

He planned on pulling out, he honestly did. But now at the end, when you’re shuddering underneath him, and crying out his name, he doesn’t have the willpower to separate from you. His body goes rigid except for the cock buried inside you, throbbing hard as his cum fills your pussy that’s still spasming through your orgasm. 

He flops down on top of you, completely drained of energy. You run a lazy hand through his messy hair and he presses his face into your heaving chest in embarrassment. “Sorry,” he manages out. “I wasn’t going to...but then it just felt...and I couldn’t stop…”

“It’s alright,” you pull him out from his hiding spot in your cleavage and give him an innocent kiss on the forehead. “I was kind of expecting that. You did great, didn’t he?”

Mirio’s practically been in a trace watching you, slowly stroking himself to what he’s just seen. “Holy shit.” His grin is somehow even happier than before. “That was even better than last time! Can I have a turn inside you next?”

You’re not surprised, you can see how hard he’s gotten again. Tamaki slides off you with wobbly limbs and you struggle to push yourself up to sit. “But the homework…” He’s reaching for you, pulling you off the bed and into his lap once more. Your arms automatically wrap around his shoulders for support, plenty familiar with this position.

“Come on, just once? I promise I’ll make it quick and then we can take a break and finish all the math, okay?” You have no ability to resist him, you never do, and only give him a tired nod in response. The head of his cock prods at your entrance; he can feel the mess already between your thighs and gives a low whistle. “Wow, you’re really soaked!” He looks over at his best friend with a laugh. “How much of that is you?” Tamaki, partially dressed, turns scarlet once again and mumbles out something you can’t really understand. Mirio presses into you without another word, and soon reaches a pace that has you squirming in his arms for more.

You’ve worked hard tonight, and you’re more than happy just to hold on and let your boyfriend do anything he wants. “That’s my girl,” he coos in your ear. “You’re so sweet. I got the best girlfriend ever, I can’t believe how cute you are.” He bounces you on his dick, spurred on by the wonderfully filthy sound of your over-fucked cunt taking every hard thrust he gives you. You can hardly keep up with him, moving slower and uncoordinated despite the strong hands on your hips guiding you. He takes pity on you and speeds up, concentrating on finishing quickly so you can rest. Despite yourself, you whimper into his shoulder as you feel your body responding eagerly to him. “Oh, babe. You’re that close already? Guess I better hurry up then, huh?”

He knows exactly what it takes to push you over and his thumb circles around your too-sensitive clit; your nails sink into his skin and your body stutters on top of him. “Tell me you want it,” he demands, his voice a needy growl that never fails to make you crazy.

“Come in me! Please baby, you know how much I love it.” You’re too far gone to wait for him, gasping hard as you come for what you’re begging is the last time for the night. You must sound pathetic, but he loves you too much to deny you anything; especially when it’s something he wants just as much. It’s a familiar comfort when he finishes inside and gradually slows his frenzied thrusts to a stop, covering every inch of you he can reach with giddy kisses.

“You really are the best girlfriend ever,” he confirms as he lets you collapse on the bed. Tamaki’s still here, and both of them work together to clean you up after all your kindness. He brings you some water as you clumsily pull your panties back on. Mirio finds you a clean shirt out of his dresser to wear; you don’t care enough to bother putting on the rest of your clothes. The three of you resume your original places and somehow manage to figure out the rest of your assignment together, even though your brain isn’t exactly in a good shape for complex equations at the moment.

It’s almost midnight by the time you’re finished, and your eyes refuse to stay open another minute. You settle into Mirio’s bed and gesture for him to join you, and turn to Tamaki. “Do you wanna stay? It’ll be tight, but I bet we can all fit under the blanket.” Mirio, of course, has no objections.

“Oh. I, um, can’t.” His shoulders slump a bit with disappointment. “I have a patrol in the morning with Fatgum.”

You snuggle into Mirio’s chest. “That’s okay,” you say, completely unconcerned and already dozing off. “See you later,” you yawn, and you’re asleep within seconds.

Mirio offers him a friendly little wave and whispers so you don’t wake up. “Text me when you’re done, we should go see a movie this weekend. Hit the light switch?”

He does, and carefully closes the door behind him. He walks back to his dorm silently, wondering how the hell he found himself in these circumstances. A faint smile spreads across his face; despite his natural instinct to panic about everything, he can’t find it in himself to worry about things between the three of you. There’s a whisper of doubt in the back of his mind that hints this arrangement can’t last forever, but he pushes it back down. For now, it’s all working out fine.

Chapter Text

Tamaki has a problem.

He’s uncomfortable around damn near everyone, so it really isn’t a surprise that he’d end up falling for the only girl who can get him to make eye contact. What began as a good-natured attempt on your part to help him out of his shell has become a worst case scenario for him. Having a crush on anyone was terrifying, but his best friend’s girlfriend? He feels like he’s taken advantage of your kindness and betrayed both of you.

Of course you’ve noticed the difference. He’d been steadily relaxing more because of the first time you slept together, but that progress quickly devolved back to square one after the second night. You’re afraid you’ve done something wrong, crossed some unspecified boundary you didn’t know about, and Mirio’s no help in the situation. Your normally sunny boyfriend tries to hide it, but you can tell that he’s bothered by Tamaki’s cold shoulder and a little hurt that they haven’t talked about it. With graduation only a week away, you beg him to try again. You and Mirio are moving in together, but Tamaki will be in another town closer to Fatgum’s agency, and you can’t stand the thought of him drifting away without an explanation.

You make sure you’re busy elsewhere when Mirio badgers his friend into a conversation. Always subtle as a brick, he pounces on Tamaki as soon as the other boy walks into the room. “Hey, are you okay? It seems like something’s been up with you lately, is all. You know I’m all ears if you wanna talk about it.”

Tamaki’s chest hurts at the offer, but he’s never been a good liar. “It’s…it’s really nothing. I’ve just had a lot on my mind lately.”

“Like what?”

He swallows hard and forces himself to continue. “I…um, I kind of really like this girl but-”

Mirio beams. “That’s great, you should ask her out! Who is it, do I know her?”

“No, it’s not great. She’s already got a boyfriend, I can’t tell her.”

“Ohhhhh, that’s a tough one. Have they been together long?” He nods and Mirio rubs his chin thoughtfully. “Man, that sucks. Maybe you’ll luck out and he’s a terrible person?”

“No, he’s pretty much the best guy ever.”

“Well, so are you!” He can tell his friend is trying to help, but it’s not his fault he has no idea. He puts all his brain cells to work and still doesn’t come up with much. “Honestly, I think I’d just tell her how I felt. Even if it doesn’t change things, knowing somebody else who’s super awesome likes her will probably be a huge confidence boost!” He laughs, missing the anxious look on his friend’s face entirely. “So, who is it?”

The name comes out as a mumbled whisper that he doesn’t catch and after a few painful seconds Tamaki says it again, finally daring to meet his eyes. “It’s her. You’re the best guy.”

“…Huh.” Mirio’s taken aback, but an idea is already forming somewhere deep in his brain.

“That’s it, just ‘huh’ and nothing else? Aren’t you mad?”

“No, I’m just surprised is all. Why would I be mad? I know how amazing she is, I totally get why you’d like her.” He gives a decisive nod. “I still think you should tell her.”

Tamaki’s groan is exasperated. “Mirio, no. She’s got a boyfriend. You’re her boyfriend, remember?”

He shrugs. “I don’t know, maybe she’d wanna have two? I’ve never thought about it before. Do you want me to talk to her?”

The room is silent for a minute. “You’d really do that for me?” It’s almost infuriating to see Mirio so happy about a conversation he’d been dreading so much. He shouldn’t be surprised that his friend is so willing to broach the subject with you, or that he’s so open to the thought of sharing your heart the way he’s shared your body.

Tamaki doesn’t hold out much hope, and is therefore blindsided when he gets a text from you two days later.

Hey! Mirio and I talked about some things and I like the idea. It’s your choice if you wanna try making this a bigger thing, but no pressure either way! Do you wanna meet in my room tonight? ❤️❤️

His breath catches in his throat and he’s immediately sweating. Before he can second-guess himself, he makes an impulsive decision to respond. Fingers shaking, he agrees and sends the message.

To his credit, it takes a lot of courage to actually knock on your door and step inside. You’re busy packing up your dorm, half-filled boxes lined up against the wall but give him a bright smile that’s somehow terrifying and soothing at the same time. “Hi, I’m glad to see you! Sorry about the mess, kinda left it all for the last minute.” You reach for him and pull him further into the room, kicking aside a hoodie he recognizes as Mirio’s.

Speaking of Mirio, he’s already sitting comfortably on your bed and browsing through his phone. “It’d go quicker if she let me help, but I’m not allowed.”

“Your idea of helping is just cramming everything within arm’s reach into one box and duct taping it closed,” you point out, your voice sounding exasperated but fond. “Anyways, do you wanna have a seat and talk?”

Tamaki manages to nod and sits on your bed while you plop down on the floor in front of them. “So, you know that I, um, really like you a lot…” He can’t look you in the eye while he speaks, instead focusing on a loose thread fraying off your shorts. “And, and it’s not as just a friend anymore.”

Your gaze is as comforting as ever when he finally brings himself to look at you. “Yeah, I know. It’s actually pretty funny, I’ve always sort of had a crush on you too.” His mouth falls open in surprise and you laugh. “What? Don’t act so shocked. I would have asked you out a long time ago if it wouldn’t have made you uncomfortable.” Your eyes flicker between them with obvious affection. “You know I love Mirio, but if I’d known sooner that both of you were an option…I’m pretty sure we would have been doing this a lot more.”

He glances over at Mirio. “You’re okay with that, too? I don’t want to get in the way, everyone knows you guys are practically married already.”

Mirio claps him on the shoulder with a laugh. “Are you kidding? I think it’s great! You’re both my favorite people, and you know I like seeing you together, so if anything this just saves us a lot of time!” It’s a bit unbelievable how enthusiastic he is about adding an extra person to his relationship, but he’s always been too good to be true. “Come on, you know I’d speak up if I had a problem with any of this.” It’s true, there’s no way he could keep it to himself if it bothered him.

“Tamaki? And how do you feel?” You offer him another kind smile and pat his knee gently. “This is a big step for you, too. If you’re not comfortable with it, you can tell us and we’ll drop it. It’s fine if you’d rather just keep it casual like we’ve been doing, or wanna go fully platonic. We just want you to be happy.” You see your boyfriend nodding swiftly in the corner of your eye, agreeing completely.

He takes several long breaths to collect his thoughts. You rub soothing patterns into his knee from your seat on the floor while, by some miracle, Mirio stays quiet and lets him debate with himself. “I think I’d be happy with that. All of us together, I mean.”

The sense of relief among all three of you is palpable. You look up at your boyfriends with a wide grin spreading across your face. “Think you wanna have some fun, then?” Tamaki gives in faster than he has any other time and you’re quick to yank the shirt over your head. You put a hand on each of their thighs to left yourself off the floor, squeezing them perhaps a bit more than necessary, and they’re happy to help you up. Mirio’s already moving from his seat, directing Tamaki further up on your bed so he can lead you onto his lap and kneel behind you. “Hey,” you laugh at their expressions, one red-faced and nervous while the other is once again beaming with excitement.

“Man, we’ve really got the best girlfriend don’t we?” You can hear the pure happiness in Mirio’s voice and offer him a kiss while he works at your bra. Tamaki makes a small sound of agreement, fumbling for your waist and you guide his hands onto you. His thumbs rub circles into your skin tentatively until Mirio pops open the hooks and throws the bra in a random direction. He stares down at your exposed breasts with wide eyes, watching carefully as large hands appear from behind you to grope at your chest. “Isn’t she the cutest?”

Tamaki swallows, throat already dry. “Y-yeah. She’s incredible.” You don’t have the words to tell them how lucky you feel to have them both now. You reach for him to run a hand through his hair and bring him down for a kiss, sighing into it as Mirio teases at your nipples. “You’re amazing,” he murmurs to you, and it warms your heart.

The three of you fall into a comfortable rhythm together with your tongue in Tamaki’s mouth and Mirio grinding his hardening cock against your ass while he plays with your breasts. He’d be perfectly happy to stay like this all night, but the rest of you are eager for things to progress further. “Hold on a second,” you pant between heated kisses and your hands touch his. “These are in the way.” With only a bit of encouragement you get him to help you shove your shorts down your thighs, wiggling just a little awkwardly to get them off when Mirio’s pressed so tightly against your back. “Much better,” you decide before trailing your lips down his neck to feel his heartbeat pounding for you.

“You’re…you look so pretty,” Tamaki whispers, barely audible over everyone’s heavy breathing. “This is real, right?”

“Feels pretty real to me,” Mirio laughs, releasing one of your breasts to grab Tamaki’s hand and move it towards the waistband of your underwear. “She’s your girlfriend, give her some attention.” You look unmistakably excited at the suggestion, how could he resist? Hesitantly he slips his fingers into your panties and groans when he feels how damp they are. His touch is so gentle as it circles your clit until you’re squirming, then shifts to push barely into your pussy.

“Tamakiiii,” you coo, pressing yourself into his hand. “You always make me feel good.” Rough fingers pinch at your nipple and you glance behind you. “Both of you do,” you praise them with an affectionate sigh. You push his shirt up a few inches to run your nails over his stomach and he gasps at the contact. “Can’t believe I get two of you,” you gush. His confidence begins to grow and soon enough two of his fingers are slipping inside you. “You’re so good to me, baby.”

Oh, he loves hearing you say that way more than he’d expected. “You d-deserve it…s-sweetheart.” He mumbles the last word nervously but the look on your face is pure joy.

“Oh my god,” you moan, glancing back to see Mirio with the same expression. “You’re so adorable, fuck.” Your hand slides lower to feel the tent in his pants. “Gonna make you feel so good too,” you promise.

You’re aware of Mirio’s hands leaving your chest, but you don’t expect it when the seam of your panties is ripped open. “Feels like it’s time to get this party going a little more,” he defends himself, aware of the lecture he’ll get later for destroying another pair of your underwear. The other side gets the same treatment and both of them groan at the sight of you naked. He returns to one of your breasts while the other arm snakes across your hip to get between your thighs. With Tamaki focusing on working his fingers steadily in your cunt, he’s got the perfect opportunity to play with your clit and make you wriggle between them. 

It’s overwhelming when they’re both kissing you breathless, rubbing against your body as eagerly as you’re doing with theirs and touching you exactly how you love. Their names fall out of your mouth in a jumbled mess, too distracted to separate them in your mind. When you come, they both feel the way you go rigid for a long moment, clit twitching and pussy clenching tight for them. They stare at you wordlessly, even Mirio speechless as you ride out your orgasm with Tamaki beneath you and him supporting you from behind.

You’re aware of a flurry of movement as you regain your senses and realize they’re taking this brief pause to strip their own clothes off. Tamaki’s dick is pretty, and you never get tired of seeing it hard for you. “I’m, um, gonna put it in now if you’re ready?”

You’re more than ready, that much is obvious. Mirio’s strong hands move to your hips to position you on top of him and slowly help you down onto his cock. You let out a pleased sigh as you take more of him into you, wrapping your arms around his neck for another kiss when he bottoms out. “That’s it. You take such good care of me,” you coo and trail your lips along the pulse of his throat. He’s grateful he’s already done this with you before and has an easier time figuring himself out, hands returning to your waist to help you up and down. With Mirio still groping at your chest and leaving kisses across your shoulders, you’re in heaven.

“Hey,” you hear his voice in your ear, low and ragged as he ruts against your ass. “What do you think about taking both of us?” You let out a shaky breath and consider it. You’ve only let Mirio fuck your ass a few times; he’s got so much excitable energy, sometimes he just can’t be trusted to ease himself into you even with lube. Still, you don’t dislike the idea, and after a bit more waffling you nod.

“Okay, we’ll try it. But you have to remember-”

“I know, I gotta go slow. I’m not gonna forget this time, I promise.” He grins at you and your heart melts at how much you love this big idiot. It takes some impressive maneuvering for him to reach into the half-open drawer by your bed by he manages to pull the bottle out. “Good thing you didn’t pack this yet, huh?” Tamaki looks on in confusion and you trace your fingers over his chest as you work yourself on his dick.

“Don’t worry, we’re just gonna try something new together, alright?” The idea of experiencing anything new always fills him with a little dread, but you’ve never steered him wrong before. It’s not hard to figure out Mirio’s plan as he watches him cover his fingers with the slippery liquid and reach down for you. You move slowly on top of Tamaki while Mirio’s hand works you open, letting out tiny little noises at his touch that both of them love hearing. “That feels…really good, babe. You can go ahead and do it now,” you insist with an unexpectedly innocent kiss to his cheek.

You cling to Tamaki for support as you feel Mirio gently push into your ass. “Can you touch me?” You don’t have to ask twice before his hand moves down from your waist to stroke over your clit and he feels the way you squeeze when you’re being overwhelmed like this. “Y-yeah, just like that,” you pant, trying not to squirm too much between them. Mirio’s still got one hand on your chest as he gradually works his big cock in and out of you, his heavy breaths an obvious sign how hard he’s working to control himself. “Fuck, you two spoil me.” 

He does his best to hold himself back but eventually presses fully inside and all three of you stop. You’re already panting hard when he turns your chin back for another kiss and gives your ass a squeeze. “You still feeling alright with this?”

You struggle to swallow with your dry throat. “I’m okay. It just feels…” you shift your hips a bit to test it. “I feel so full,” you moan, planting your hands more firmly on Tamaki’s shoulders. “I think I like it.” After another minute to adjust yourself you feel more confident about your position. “You guys can start moving again.”

Mirio needs no further instruction to start fucking you. He has enough sense to go slower than usual, but you’re sure that wont last all night. You hear the gasp from Tamaki who stares at Mirio with wide eyes before finally speaking again. “Shit, I didn’t know I’d be able to feel you inside her.” Heat prickles down your spine, why does that turn you on so much?

Mirio’s laugh is more ragged that normal but genuinely delighted. “Really? That’s so cool! Come on, you do it too.” The encouragement is welcome; after a moment he resumes thrusting into your cunt and earns a muffled growl from the man with his face buried in your neck. “Wow, you were right. I can feel you moving inside too, this is awesome.” He looks at you with a smirk. “And I bet it’s gotta be even better for you, huh?” It is, you’re being stimulated in a way you’ve never experienced before and it makes you feel like raw electricity is flowing through your veins.

“It’s a lot but it’s great,” you whimper, moving back and forth between them. It’s clear that you’re the one in control here, setting a pace that allows you to give them equal focus without tiring yourself out. They busy themselves with your body instead, kissing and touching every inch of you they can reach while you fuck yourself on their cocks. Their constant attention to your nipples and clit is driving you crazy, and you know it won’t take them long to drag another climax out of you. “You’re perfect,” you huff between ragged gasps. “Both of you are so perfect.” Buried so deep inside you, they can tell you’re coming as your holes clamp down on them. You’re too distracted with yourself to enjoy the sounds they both make, but you’ll definitely have more chances to hear them in the future. Tamaki grinds to a halt to steady you, allowing Mirio to finally speed up to a pace he’s more used to. You return to your senses with his dick moving roughly inside you and Tamaki still teasing your clit with feather-light strokes. “Guuuuys,” you whine. “I need a break for a second.”

They give you the time you need, Mirio fumbling to grab a glass of water you left on your drawer earlier. You take a long drink before passing it to them and you all take a moment to catch your breaths. “You okay? I don’t think I’m gonna last much longer after that,” he warns and Tamaki makes a rough sound in agreement. You wouldn’t mind a longer break, but you’re determined to help them finish before the adrenaline wears off. You begin rocking your hips between them again, signaling you can handle a bit more for your boyfriends. “Love you so much,” he murmurs in your ear and kneads a handful of your ass to spur you along.

You’d never call them greedy, but neither of them can keep their hands off you after that. Your brain feels like it’s short-circuiting with every brush of their fingers over you, and you can already feel the familiar tension in your belly when Tamaki’s grip tightens hard on your hips and forces you down to meet him. You feel him come inside you with a sweet breathy whimper of your name and all the energy left in him flows out. His grasp goes limp and he simply stares at the scene in front of him in a daze, a small but content smile tugging at the corner of his lips.

“Don’t stop yet,” Mirio orders from your other side. “I just need a little more, okay?” You can tell Tamaki feels like jelly but he obeys, sloppily thrusting inside you again to keep the moment going. You give permission for Mirio to go faster, hoping to end this before Tamaki gets overwhelmed. He’s happy to pull you tighter against his chest to fuck you with quick, deep strokes that leave your head spinning. The groan he lets out is so appealingly filthy you almost wish he’d keep going, but you relish the massive hug he wraps you in as he showers you in kisses and both of them finally pull out of you. Tamaki has to scoot all the way to the wall to make room for both of you to flop down on the bed with him, but it’s worth it when you’re laying between them with the biggest smile on your face.

“That was…we’re really idiots for not doing this sooner.” They laugh at your observation, tired but happy. You turn over to face Tamaki and rest your head on his shoulder. “Still interested? I can’t promise there’ll be a threeway every night like this, but you know how much we’d love to be with you.”

You watch the blush spread to the tips of his ears. “Definitely still interested. Uh, I don’t exactly know what I’m doing with being in a relationship, but I’ll try my best for you.” 

Mirio, always ridiculous, lifts his arm for a high-five that’s exhaustedly returned. He gives your thigh a squeeze that makes you very aware of the mess all over your lower body and the bed. “Ugh, I’m gonna need to go clean up,” you force yourself up begrudgingly. “Can you change the sheets? I already packed the clean ones, but it shouldn’t be too hard to find the box.” They help you to your feet without complaint and you return a few minutes later wearing a fresh tank top and underwear. The bed’s been remade, but what gets your attention is the sight of Tamaki with his tongue shoved impressively far into Mirio’s throat. “Oh, hello.” Tamaki looks almost embarrassed when they separate, but Mirio is just as sunny as ever.

“Um, we were-”

You shake your head and ruffle his hair with a smile. “He’s your boyfriend too. I’m just disappointed you didn’t wait for me to get back first.” You both give him a kiss on his burning cheeks and you squeeze his hand comfortingly. “I wanna see a lot more of that going forward,” you tease and stifle a yawn.

Mirio’s returned to his original spot on your bed and pats the small space next to him. “It’s getting kinda late, think it’s time we call it a night?” You agree, pulling Tamaki with you. The mattress isn’t nearly big enough for all of you to fit comfortably, but it’s only for a few more days. You’ve already bought a larger one for your new place, and you can always find something even better in the future when Tamaki’s ready to move in full-time. You fall asleep easily, cuddled between the two men you love most and more excited than you’ve ever felt before.
