Bokuto Koutarou:

He’s the type to spring to the other side of the room the second he hears the word “Chumbawumba” fall from your lips. 

It’s a mewl and whimper all wrapped in one that swiftly and harshly rip his heart in two. 

While you crush a pillow against your chest to try and assuage the pain, a wave of horror dawns on Bokuto’s face. He’s watching every move you make to ensure you’re still actually breathing just as the first tear slips. 

Soon, it’s not alone as he starts bawling, his whimpers and sniffles leaving his face a damp, mucus-drenched nightmare.

“Oh Bo...”

“YN I HURT YOU!” 

You could physically watch as that fact ate him up from the inside out. First, he crumpled to his knees, and then he hugged them to his chest. Muffled sobs echoed around the room louder than your cries of pleasure ever had, leaving you to wallow in pity as your boyfriend beat himself up. 

“Bo, I’m okay, I promise.”

It’s a struggle at first, but you still attempt to ease yourself off the bed. Bokuto’s ears perk and his head raises but the second he spots you reaching out for him he springs to his feet.

“NO!” Tears start falling even faster when he notices how you flinched at his cry.

“Please, YN,” he continues, voice lowered, “I don’t want to hurt you again.”

Pursing your lips, you try to take another step but he presses himself harder against the door, hand scrambling for the knob. Just as he finds it, you pounce on him, snatching his wrist and yanking it towards you.

“YN wait-”

“Shut up,” you huff out, gripping him even tighter when he starts twisting and tugging his arm. Without missing a beat, you yank the hand towards your body and press it just over your heart.

His fingers are cold against your hot, sticky skin, but that doesn’t stop you as you watch his expression, waiting for a reaction. 

“...Why?”

“Because Bo,” you roll your eyes and press both hands over his own, “my heart is still yours, no matter how many times you get a little rough in bed.”

He’s silent as he studies your hands on his, even more so when he raises his other to wipe the saltiness from his cheeks. 

“I... I never wanted to hurt you, YN. Not in a million years.”

“I know, babe. And that’s what the safeword is for,” you gesture back to the bed. “Remember? We came up with it so you wouldn’t accidentally hurt me, and that’s all that was--an accident.”

He sniffles once more before nodding. “Okay.” The hand on his own cheek transferred to yours with a hesitancy you had never felt before. When his fingertips met your skin, he sighed in relief, cupping the side of your face and running a thumb just over the rosy apple of your cheek.

You smile and press a kiss into his palm. “All right, how about we watch a movie instead?”

“I don’t think-”

“If you go out and get my favorite candy, I might just give you forgiveness cuddles.” His eyes glowed with anticipation. 

As always, Bokuto was only willing to accept your kindness by working for it; he never thought he deserved it otherwise. That’s why the second you suggested the offer, he zipped out of the room in only his boxers and T-shirt.

“I’LL GET YOU ALL THE BOXES, BABY, JUST YOU WAIT!”

“Bo, don’t forget-”

“SHIT, MY SHOES!”

Tsukishima Kei: 

He knows it before you even whisper “ginger shrimp.”

Your lips formed into an “o,” but not a good “o.”

Tsukishima’s eyes widen before he turns away, climbing off you and reaching for his glasses. They clatter to the floor and he leans down to grab them, trembling hands unfolding the lenses and pushing them up his nose. 

“I’m sorry,” he grunts. His voice is hoarse and quiet; less scathing than you had ever heard it. Even in a moment like this, you wish you could see his face but his back is turned toward you completely. 

“Tsukki...”

“I’m going to... go get you an aspirin and a glass of water. E-excuse me.” 

Shock encompasses your face the second you hear your boyfriend--your overly-critical, always-sarcastic boyfriend--stutter for what must have been the first time in his life. 

You don’t bother to point it out though because the door is already closing behind him the minute you shake yourself out of the daze. 

His bedroom is silent, but not the comfortable silence you and him are both used to. It’s painful and awkward and worries you about whether Tsukishima will even bother talking to you for a while. 

You can’t even hear a sound in the rest of the house because the atmosphere is so dark and heavy. A lump forms in your throat and you glance at the clock. 

Ten minutes.

Ten minutes have passed since he said he would leave to get you a painkiller. It didn’t even hurt anymore at this point, and truly what surprised you the most was how hard Tsukishima took it on himself. 

You decided to go investigate after another five minutes ticked by. 

The hardwood floor left a flood of chills racing up your body as you tiptoed through his room and out into the hallway. With only his thin sheets to keep you covered, you sneaked down the stairs and padded into the kitchen.

No luck.

His white blanket dragged along the floor as you traveled past the small opening into the living room, finally spotting your boyfriend.

Long fingers tangled into blond hair as his back curled over, elbows stuck on his knees while he cradled his head. 

You chose to stay silent and not disturb him, instead making your way over and plopping onto the cushion next to him on the sofa. He raised from his position and turned to you, eyes snapping open. 

“Sorry, I didn’t get your-”

Your arms wrapped around his neck as you twisted your body to trap him in a hug. The sheet slipped down your body but you didn’t bother adjusting it, not when there were more serious matters to handle. 

“YN...”

“Shut up,” you dug a hand into the nape of his neck, shoving his face into your collarbone. “I’m fine, you doofus. You didn’t kill me; I’m not as fragile as you think.”

You felt his jaw clench against your chest before he huffed, not-so reluctantly returning the hug with his arms around your waist. 

The living room was silent for a moment, just you and Tsukishima soaking up each other’s presence in the early midday hours with only the birds outside to keep you company. His skin was warm and bare against yours, but, unsurprisingly, his fingers were colder than ice. 

“I told you that was a bad idea, you know.” And there it is. 

At least it was nice while it lasted. 

Tsukishima pulled away and glanced your body up and down in what he must’ve thought was a discreet way. 

“It sounded like fun, you know. At least I thought you would’ve liked it.”

He set his jaw. “If it meant you never getting hurt again, I’d say we should stick to vanilla from now on.”

“Aww, but where’s the fun in that?”

Kuroo Tetsurou:

In the beginning, it felt good. 

“Yeah, kitten, you like that?”

Amazing even.

“Oh fuck, Tetsu, don’t stop!”

Then it… didn’t. 

“Shit, pineapple! Pineapple!” you wheezed, shoving his hips away and squeezing your legs together. “Fuck.” You rolled onto your side and pulled your knees to your chest, trying to breathe while a dull pain shuddered through your lower half.

Without another word, Kuroo slipped off the bed and observed you, wincing at the way you shut your eyes so tightly. His hands hovered over your form, wanting to help but… just not knowing how. 

His heart pinched, thundering in a way that only came from fear. “Are you okay?” he choked out, finally letting a hand fall to the skin of your back before massaging up and down. 

“Yeah,” you nodded, “Yeah, I’m good. I just, uh, just need a minute.”

“Of course, Kitten.” In an instant, he was settling in behind you, both arms slipping around your form and long fingers pressing against your stomach. “I’m so, so, so sorry,” he peppered kisses along your shoulders and up your back, “So, so sorry, baby.”

“It’s okay, I promise,” you relaxed in his grip, slipping one hand out from between your thighs and intertwining it with the familiar one on your stomach. “Let’s just… not do that again, okay?”

Kuroo scoffed, shaking his head and curling closer around you. “Kitten, you best believe the next time I even hear you say “pineapple” in public, there’s like a 50-50 chance I’ll have a heart attack. We’re not doing anything like that for a while.”

You snorted. “Anything? Really?” 

“Well of course not anything, but-”

“I knew it.”

“Hey!” Kuroo squeezed your side, and a corner of his mouth lifted at the way you jolted. “I’m sorry. Really, I am.” His voice wavered, and you just knew that if you could see his eyes, there would be a war happening in them. Guilt and despair would be battling it out right in those hazel orbs of his. 

“Tetsu, it’s not your fault!” you reassured, hiding a grimace as you swapped sides to face him. “Now we know what’s too much, right? I promise, I’m okay.” A warm smile took over your face as you cupped his own, leaving a brisk kiss against his lips. “Don’t get all sulky on me now.”

“Never,” he smirked, wrapping two fingers around your right wrist to press a kiss into your palm. His eyes never left your face, and in them you could see worry--worry and something more.

Oh.

It was pain. 

“Oh Tetsu,” you were quick to wrap him in a hug, your arms around his neck while his hands wandered up to your shoulder blades to keep you close. “I’m okay, I swear. I know you didn’t--and you would never--mean to hurt me. Please. It’s okay.”

Finally, the tightness in his muscles faded under your hold. “I know, YN, it’s just that I hate that I’m now someone who’s hurt you. I never wanted to be that guy.” His face pushed harder into your collarbone and his teeth gritted. “Especially to you.”

You shook your head and smiled. “But that’s the thing, Tetsu. You’re not. The only thing you are to me is the man I’m in love with-”

“And your best lover.”

“…Yes, and my best lover. Sure,” you scoffed, rolling your eyes as a grin grew on your face. 

“Thank God. It’s so much better to hear out loud than to read it from your diary.”

“Tetsu!”

Kageyama Tobio:

Your safe word was simple. So simple you never thought you’d have to use it.

“Stop! Stop!”

Until now, of course.

“Fuck!” Kageyama opened his lust-filled eyes, yanking himself away so hard he crashed to the floor of his bedroom. 

You, on the other hand, groaned and pressed two hands between your legs, gasping for air while trying to fend off tears. Pain shot up your spine and ebbed into your hips where Kageyama’s hands had been. The haze of passion that had fogged the room was zapped away in mere seconds, replaced with a dead silence. 

Your boyfriend scrambled off his floor and popped back up to his feet, pausing at the sight of you with furrowed brows. 

“YN…?” His tone was slow and concerned, yet his mind was anything but. When you didn’t respond, Kageyama’s diminishing self-control disappeared completely. 

“Shit,” he hissed, two hands diving into his hair and yanking at the strands without restraint. “Fuck!” His face grew red with anger, teeth bared like a wolf ready to attack. But it wasn’t you he was aiming for.

No, no, it wasn’t you. It was himself. 

“I’m so fucking stupid,” he grunted, backing away until he crashed into his own door. “Why did I do that?”

“Tobio-”

Your tone was insistent, wanting to be reassuring. All Kageyama could hear was the pain you struggled to hold back. 

“No, YN!” he barked, turning and slamming a hand onto the door knob. “I hurt you!” 

“Tobio, you’re overreacting! I’m fine!” You weren’t lying; the pain was fading away by the second. The only thing that hurt now was the way Kageyama tried to avoid you.

He whipped the door open anyway, only to stop at your final plea. “Tobio, please!”

It wasn’t the words that made him stop; it was the crack of your voice, caused only by a sudden onslaught of tears. “Please,” you sniffled. “I’m okay, I promise. Just don’t leave.”

Kageyama’s head fell, yet little by little, inch by inch, he let the door squeal to a close. Five, ten, maybe even twenty minutes passed before he turned and made his way back toward you, feet scuffing with every step. 

Your tears had stopped by now, but your eyes were nowhere near dry. “Tobio.”

Kageyama refused to meet your gaze, but he still climbed back onto the bed just across from you, letting his legs cross one over the other. 

Finally, his hands reached out and grasped one of your own, pulling it towards him and propping his elbows on his knees to give him the right height to hold it against his lips.

“I’m sorry,” he whispered, each word warm against your fingers. “God, I’m so, so sorry,” his grip tightened. “I just hated hurting you like that. And I couldn’t stand that I did it during a time where I should never hurt you, YN.”  

“Tobio…” you paused, only to think of the words that wouldn’t scare him off. “I… I know you must feel like this is the end of the world or something, but it’s not. Really, I promise. I still love you, and I still trust you, completely. Nothing has changed.”

He still hadn’t looked up, but his fingers began to run along your hand in a nervous habit. 

“You didn’t hurt me. It’s sweet of you to worry so much, but really, you didn’t. Do you want to know what did hurt?”

No response.

“Okay, I’ll tell you,” you sighed, shaking your head. “It hurt when I saw that you wanted to leave so quickly. Can you… can you promise not to try and run away every time something that you can’t control happens? I want to experience everything with you, including hard times, so please don’t just… run away where I can’t follow. Can you promise me that?”

Kageyama was dead silent, and part of you was convinced he may have fallen asleep in the midst of your rambling. The only reason you knew he was conscious was because of the way his fingers kept tracing over your hand. 

“Are you-”

“I promise.” Kageyama raised his head, and for the first time in what must have been nearly a half hour, he made and kept eye contact with you. “I promise I won’t leave like that again, no matter what happens. I want to stay by your side forever.” 

“But…?”

“But,” he clenched his jaw, and in a surprising turn of events, a tear slipped down his cheek, “but I don’t want to hurt you again, YN. I still hate myself for doing that to you.” His voice was solid, unwavering. It was obvious he wouldn’t let this go for a while. 

“All right,” you nodded, sliding closer to him on the mattress and pressing your hand against his chest. The other, still caught in his grip, wiggled in effort to escape. He refused at first, gripping just a bit tighter before letting go completely and dropping his hands onto his lap in the form of curled fists. Finally free, you left both palms resting flat against his chest. “All right, I’ll let you sulk for a while.”

Then you put pressure on his chest, urging him to lie back in a form that was obviously the last position he wanted to be in. With enough force, he relented with furrowed brows and fell onto his back. “YN-”

“Feel free to frown,” your face hovered over his, doused in a nonchalant expression, “and whine,” you threw one leg over his body, “and bitch until your heart’s content.” You plopped down onto his lap, effectively straddling him and his… you know. 

“Just know that while you do that, I’m gonna be by your side,” you smirked, letting your hips slide back before dragging them forward again, “kissing and hugging and-”

“YN,” he choked out when you ground yourself on him once more, hands slamming down onto your bruised sides. “Don’t-”

“-making love to you just as much as you make these little efforts to punish yourself.”

“Fuck,” he grunted. 

“Tobio, just know that I’m in love with you more than you hate yourself,” you ground into him again, eating up the way his eyes rolled back into his head.

“So it’s gonna be a long ride.”
