Lip Smacker - m.

⤷ summary: in which izuku, katsuki, and shouto make a bet about what flavor chapstick you wear.

word count: 4.8k pairing: tdbkdk | fem!reader warnings: none ♡ genre: crack, smut | lime author’s note: This is a COLLEGE AU, meaning all characters are aged up to 18+ consenting adults—more specifically all characters are in their 20s.

If there was one thing about you that everyone knew, it was that you were not one to shy away from PDA with anyone. And by anyone, that means anyone. It was no secret you were overly-affectionate, especially with your friends. It wasn't a bad thing, just a little jarring at times.

You were a big cuddler. It was absolutely normal to embrace one of your friends and hold them hostage on the common room couch. It was practically routine. Holding hands was another habit of yours. You hated walking to class alone, and whoever you convinced to go with you would have your hand tightly wrapped around theirs the entire time.

There were other ticks too, like how you’d sit on the nearest person’s lap even if there was space for you elsewhere, or when you essentially tackle your friends into a hug when you got too excited, which was surprisingly quite often. It’s just how you were, and your friends had long since accepted that.

There was one thing, however, that a certain group of testosterone-heavy someones couldn't wrap their heads around. As harmless and simple as it may have seemed to you, it really stirred up tensions with your guy friends. Out of all your little ticks, there was one tick you loved to do the most, and that was kiss.

It wasn’t a sexual thing. In fact it was far from it. You kissed everyone, including your girl friends. Truthfully, you kissed your girl friends more often than your guy friends, but it didn't change the fact that you kissed a lot. Like... a lot. So much so that the guys of your dorm have a bit of a competition around it.

You see, you were a very pretty girl. You were sweet and kind, and adorable, and all the things guys fawn over in a spritely young woman such as yourself. Having someone like you around the dorms was a blessing for them. A pretty girl who isn’t afraid of some platonic touching with the opposite sex? What an absolute win!

“I’m telling you guys, y/n totally wants me!” Denki burst into the common room.

“Did you take the stairs? Why are you sweating?” Mina asked, turning around on the couch to face him.

“Yeah, the elevator was too slow,” he huffed, throwing his bag on the floor and jumping onto an empty chair.

Jirou scrunched her nose. “We live on the third floor why are you sweating that much?”

“Oh my GOD, did you guys not hear what I said?” Denki groaned, changing the subject. “y/n wants me! She wants my plug in her outlet, and she wants me to stick it in and out all night long!”

The room erupted into a sea of disgusted groans. A rogue pillow found itself impacted in Denki’s face, courtesy of Mina.

“Ew, dude?!” Jirou cringed.

Kirishima shook his head disapprovingly. “Come on, man. Not cool.”

“That’s just gross,” said Sero.

“Trust me, the last thing y/n wants is any of...” Mina gestured to Denki. “that.”

“I know I am going to regret asking you this, but what happened to make you think that she wants you.” Kirishima curiously asked.

Denki smiled and excitedly made his way to sit on the open seat between Mina and Kirishima.

“I was walking back from class, right? And I saw y/n walking to class on her own. So, I ran up and offered to walk with her there. She smiles all big, bats her eyes and goes ‘Oh Denki, thank you so much! I’m so happy you’re here! Why don’t you just take me already, oh-hoo-hoo-hoo~!’”

Jirou rolled her eyes. “She did not say that.”

“She might as well have!” He countered rather defensively. “Anyway, she takes my hand and––dude, she’s so close to me I can smell her shampoo—she's brushing against my arm, laughing at all my jokes; and when we get to the science building she’s all big-eyes and pouty lips, ‘Thank’s again Denki, you are such a good friend,’ and then, boom! She lays one on me, right here!” He points to his left cheek where there was a faint pink glossy mark.

“Oh, so like, what she’s like with literally everyone else,” Sero bleats.

“Nah man, you weren't there, you didn’t see the way she looked at me! Those were fuck me eyes, I’m telling you.”

Jirou suddenly stood from her seat in the lounge chair. “Seriously, guys? If you’re gonna keep talking about y/n like that, I’m leaving. You guys are gross. Animals.”

“Yeah, I’m out too.” Mina followed Jirou to their room leaving the boys to themselves.

“I don’t know what they’re so mad about. They get to room with her. If I got to share a room with y/n I'd be the happiest man on earth,” Denki swoons.

“Yeah because you’d be the last man on earth, dipshit,” Sero snickers, causing the others to laugh.

Denki’s cheeks turn red. “Whatever! You guys are just jealous because y/n likes me the most.”

“What, because she kissed you once on the cheek? Please, she’s kissed me at least three times,” Sero not-so-humbly brags.

Denki shoots up from his seat. “No way!”

“Yeah, and even then, it’s obvious who her favorites are, and—newsflash—it's not you or me.”

Just as Sero was picking apart the last bricks of hope Denki had left, the elevator dinged, revealing the other occupants of the floor.

Kirishima smiled. “Sero’s right. Your little science building peck ain’t got nothing on whatever the fuck those three got going on with her.” He gestured to the three boys who leisurely walked in.

“What are you guys talking about?” Izuku asked as he stepped from the elevator with Katsuki and Shouto following behind.

“We were just trying to see which one of us is y/n kisses the most to figure out who her favorite among the guys is,” Sero answered.

Katsuki sucked his teeth, his already permanent frown deepening. “Do you idiots really have nothing better to talk about?”

“It’s easy for you to not care when she’s all over you 24/7,” Denki pouts. “‘Katsuki can you open this for me please? Katsuki can you walk with me to psych? Katsuki can I lay on your lap while you play overwatch?’” Denki offensively mimics the sound of your voice.

The common room erupted into snickers, turning the hot-headed blond’s neck red. “Watch it, dumbass,” he warns.

“Well, if you’re really that curious, I believe it's me,” said Shouto confidently, earning everyones attention.

Katsuki’s brow twitched. “Oh, yeah? What makes you think that Icy-hot?”

“I can think of many occasions when y/n has kissed me and most of them were on the mouth. I think that would make me the favorite,” he stated as if it were fact.

It was this revelation that captured the attention of everyone in the room with great surprise.

“You’ve kissed y/n on the mouth multiple times?” Sero gawked.

“She kissed me,” he clarified cooly.

“No way Shouto kissed y/n on the mouth before me!” Cried Denki dramatically, causing Shoji to comfort him. “That sneaky bastard preyed on our sweet, innocent girl and took advantage of her!”

“I told you, she kissed me,” Shouto reiterated once more, becoming increasingly irritated.

Kirishima gave a heavy-handed pat to his back. “Congratulations, dude! I didn’t know you had it in you,” he smiled encouragingly.

Katsuki scoffed and crossed his arms. “So what? y/n’s kissed me on the lips too, and some of them weren't just innocent pecks neither.”

A strangled cry muffled by Shoji’s chest escaped Denki’s lips.

“Guys should we really be talking about this?” Izuku shifted nervously.

“Don’t go acting all high and mighty, Deku!” Yelled Katsuki. “I saw you and y/n kissing at the culture festival last month!”

“Stalk much?” Sero muttered snarkily under his breath. Izuku’s cheeks went red and a coy smile spread across his lips. “Well...”

Denki broke free from Shoji’s strong arms and rushed towards Izuku, taking him by the collar. His reddened cheeks were stained with tears and nostrils flared. “Is this true Midoriya? Please, tell me it isn't true!”

“It is,” Izuku admitted, completely flustered and somewhat scared of his passionate, but clearly deranged friend.

Denki fell to his knees. “You have to tell me what it was like! Was there tongue? How soft were her lips? What did she taste like? Tell me, I need to know!”

“This is getting sad,” Kirishima frowned, genuinely concerned, and Sero nodded in agreement.

“I-I don’t know,” Izuku stuttered. “It was nice, I guess...” His mind went back to the day she kissed him at the festival by the taiyaki booth, and all the other times she’d placed her lips on his. He smiled softly. “Her chapstick tastes like watermelon.”

Denki smiled. “Watermelon,” he hummed. “Why didn't I think of that, that’s perfect for her! Fresh and sweet, just like her!”

“It’s not watermelon, idiot,” Katsuki spoke up. “It’s vanilla. It's always been vanilla.”

Izuku furrowed his brows. “Vanilla?”

“Now that I think about it vanilla does suit her style better,” Denki muttered to himself. “I think Bakugou might be right on this one!”

“No, I’m pretty sure it’s watermelon,” Izuku asserted.

“Strawberry.”

Everyone turned to Shouto, who all of the sudden looked very serious. “Her chapstick is strawberry flavored.”

The three boys locked eyes in an intense stare-off. Kirishima and Sero shared a look and identical smirks, hatching the same idea.

“Why don’t we make this interesting,” Sero cut in, his mischievous grin glinting. “Why don't we make it a bet? Watermelon vs. Vanilla vs. Strawberry. Whoever is right can claim that they’ve kissed y/n the most, and therefore is her favorite.”

“I’ll take that bet,” says Izuku confidently.

Katsuki scoffed. “You seem pretty confident for a jackass that’s about to lose!”

“The same could be said about you too, Bakugou” Shouto quipped, poking the blond’s already short-temper.

While the three fought, the rest of the boys that still littered the room placed their educated bets, spreading the word to the others in a group chat. Soon all of class 1-A and some of class 1-B had placed their bets on what flavor chapstick you wore.

All of this, of course, was unbeknownst to you as you were conveniently left out of the betting chat, along with Mina and Jirou as were your closest friends and would undoubtedly blab to you about the whole thing. You had to be kept in the dark, which made the events of the following week rather...interesting.

It started the next day, after bets had been placed and the tension between Shouto, Katsuki, and Izuku manifested in their sudden desperate efforts to cater to your every need. You didn't suspect anything at first. You’d just assumed that the boys were being kind.

You woke up early, two hours earlier than when you needed to be up in preparation for your first class. It was sunrise and despite you still being tired, you couldn't fall back asleep no matter how hard you tried. Giving up, you slipped from your bed and into your robe and slippers. Groggily, you made your way to the kitchen to make yourself a mug of coffee to sip on while you watched TV in the common room until you decided to start your day.

It was there that you ran into Shouto, standing in his pajamas over a hot stove cooking a fried egg. His back was turned to you and you debated announcing your presence. However, you should have known the son of the number one hero was always incredibly keen on his surroundings.

“Would you like some?” His question hung in the air, waiting for you to catch it.

“You don’t have to,” you sputter, suddenly flustered. “It looks like you’re almost done. I was just getting some coffee.” You said as you stood at the kitchen island.

Without saying a word, he grabbed the bowl full of fried rice at his side and slid the fried egg on top, drizzling a demi-glace sauce on top before turning around and placing it in front of you. He took your mug from your hands and replaced it with a spoon. You watched him, almost starry-eyed, as he placed your mug under the coffee machine and pressed the button to make it brew with coffee. He said nothing, and made himself another bowl.

You smiled softly and took a seat on a stool at the island, deciding to watch him cook instead of another episode of Too Hot To Handle.

“Thank you, Shouto,” you said as you scooped a spoon full of rice into your mouth. You hummed in delight.

Shouto’s lips twitched into a barely-noticeable smile, not that you could notice it with his back facing you. “Do you like it?” He asked.

“I love it!” You praise. “I didn’t know you could cook so well!”

Shouto did the same as he did before, taking his bowl of fried rice and covering it with a hot egg and demi-glace sauce. He found himself a spoon and walked over to the coffee machine, which had filled your mug with hot, black coffee. He grabbed it too, and came over to take a seat at your side. Reaching his long arms to the center of the isle he brought closer the sugar and creamer for your brew. You thanked him again.

“My sister Fuyumi is the better cook,” he told you. “She taught me how to make a few things for myself while I am away at university. Quick, simple meals, like rice and ramen. Nothing special.”

“Thank goodness for your sister then,” you said. “Maybe I should wake up this early everyday so I can steal more of your delicious breakfast, simple or not.”

You giggled to yourself and took another bite. Shouto watched you from the corner of his eye. He’d never seen you like this, in the morning with a fresh face and your hair tied back, dressed in your pajamas and a robe that hung loosely off one shoulder.

It is in moments like these, when Shouto finds himself alone with you that he is reminded of your magnetic attraction. Even he could not resist it, the thing about you that cast a spell upon all those you meet, rendering them your adoring subjects. He ate silently beside you, only occasionally engaging in small talk when you incited it. When you had finished, he reached for your empty bowl, prepared to clear it for you, but your hand gripped his wrist. You stood from your stool.

“The least I can do is clean the dishes. You should go. I know you’re only up this early to train before class.”

Though it was your hand that encased his left wrist, it was he that felt burnt by your touch. You took the bowl from his hand and collected his from the isle counter to wash, but not before you stood on the tips of your toes to plant a soft peck to his lips on your way to the sink. It was sweet, innocent even, perhaps only lingering a half-a-second longer than it should’ve. But unlike the many previous kisses you’ve shared before, he licked his lips and could not help the smirk that appeared in response to the taste of candied strawberries that lingered on his tongue.

“I was right,” he muttered to himself.

You raised an eyebrow. “Right about what?”

Shouto cleared his throat, his cheeks tinted pink. You’d never seen him do that before.

“I mean, you were right,” he corrected himself. “I should go. I’ll see you later, y/n.”

You nodded your head. “Oh, alright. See you later!” You called after him as he left to return to his room.

The rest of the day went on rather normally. You had gotten ready and got to class on time (something that was rare) feeling particularly spritely and energized. You assumed it had something to do with having an actual breakfast instead of a singular mug of coffee. You reminded yourself to thank him properly the next time you saw him.

Around lunchtime was when you encountered Katsuki. You had just gotten yourself lunch from one of the dining halls to eat at one of your favorite spots outside. It was a particularly nice day, especially for the dead of winter, so you decided to not let it go to waste. On your way there you saw a familiar mess of blond hair ahead of you.

“Katsuki!” You yelled excitedly, quickening your pace to catch up to him.

His shoulders tensed and he stopped in his tracks, craning his neck to look behind him and expected to find someone annoying headed his way. He relaxed only a little when he saw it was you. Still someone annoying, but a lot less annoying than all of the people he knew. Once you reached him you gave a bright grin. The sun shone down on you, igniting the highlights of your hair and the color in your eyes, imitating an almost heavenly glow; the kind that even he couldn't deny made you look perfect. It was one of the many things about you that pissed him off.

“Where ya goin’?” You asked in an almost sing-song voice.

“Back to the room to take a nap, why?” He grumbled.

You held up your plastic bag of food. “Want to have lunch with me? I have extra.”

“No.” He said simply and began walking towards the dorm.

You pouted, a small whine came from your chest and you chased after him. “Please, Katsuki?” You begged. “I don’t want to eat alone today. Besides, who else is going to help me eat all this spicy pork curry?”

He sighed, once again stopping his journey to his comfortable bed that had been calling his name since his 8 AM class. You smiled triumphantly, knowing you had won. He looked down at your heavy plastic bag full of what he now knows is spicy pork curry and other side dishes. Sucking his teeth he grabbed the food from your hand. “You’re lucky I’m fucking starving. Why buy so much if you weren't going to eat all of it?”

He nagged you all the way to the campus arboretum, where you had a special place among the grass and trees you liked to sit and eat at. He was only giving you a hard time because it kept him from thinking about how pretty you looked in your dress, or how cute you had sounded begging him to come eat with you. He didn't want to think about how your arm often bumped his because you had an awkward, lop-sided gait, or about the smell of your perfume. All he wanted to do was get to your picnic spot and eat. So he did.

The two of you ate together on a blanket you had brought. You’d gotten on the topic of final exams which turned into a shit-talking fest about who you both felt in your class would pass and who would fail. He found it very easy to talk to you and you never made him feel bad about the things he said, unlike most people who spend most of their energy scolding him instead of just talking. Not you though. You always let him talk.

It was when he said something that made you laugh that you accidentally spilled your soda on your dress. You cursed and fumbled for napkins to dab it clean, but the stain was evident.

“Dammit!” You groaned. “I have class in fifteen minutes I don't have time to change.”

You were so busy cleaning your mess, it wasn't until you felt the weight of Katsuki’s thick hoodie plop over your head that you knew he had even taken it off. You snorted a chuckle and pulled your head threw the neck hole to see him left in his black compression shirt.

“Take it dumbass,” he told you.

“You won’t be cold?” You asked.

“I’m done for the day. Just bring it to my room later.” He said.

You smiled and pushed your arms through the sleeves, pulling the oversized hoodie over you to cover the stain. It was...toasty, you think is the correct word, and it smelled like his cologne. You closed your eyes and held the fabric to your nose, inhaling his scent deeply. Katsuki furrowed his brows as he watched you.

“It smells so good!” You practically moan. “And it’s so warm. It’s like I’m getting the best hug in the world. A Kaachan hug!” You teased, snickering to yourself.

Katsuki’s face grew hot, and he pinched your cheek, tugging with his fingers, making you yelp and whine from the minuscule pain. “Who told you to call me that, huh? Can’t you just say thank you like a normal person? I can take my hoodie back and let you walk around with a shitty stain on your dress.”

Your hand gripped his arm, attempting to pry him off. “Okay, okay!” You yell, half laughing, half hissing in pain. “I’m sorry! Thank you!”

Satisfied he let your cheek go, and you soothed the spot by rubbing it in circles with your hand. You pouted while he cleaned the blanket of your mess and threw the trash away while you folded it back up. He decided to walk you to class since he had nothing better to do and he knew you wanted him to (certainly not because he wanted to). When you made it to the entrance of your building you stopped and turned towards him.

“Thanks for walking me and for the hoodie,” you smiled. “I’ll see you back in the dorms.”

You started to turn around when you felt his hand wrap around your arm, keeping you in place. Confused, you stood still. You might have been imagining things, but from where you stood, it looked as though his cheeks were flushed red.

“What’s wrong, Katsuki?” You asked, concerned.

“Don’t I...get a kiss?” He couldn't believe what he was saying.

“A kiss?” You repeated, also not believing what he was saying.

“As a thank you,” he explained.

Your lips twitched into a teasing smile. “I thought you didn't like it when I did that in public.”

“When has that ever stopped you before!” He countered, his cheeks growing redder.

You laughed and took a step closer, closing the gap between you. You craned your neck up to place a chaste kiss on the corner of his lips. Unsatisfied, Katsuki sucked his teeth and reached his hand up to your chin, turning your head in a position for him to press his lips against yours, and kissed you. It was unexpected, but after a few seconds, the shock drifted away, and you closed your eyes, returning the kiss. It was longer than the kiss you shared with Shouto earlier that day, but not by much; and once it was over, he licked his lips.

‘Vanilla...’ He thought as he pulled away.

His hand fell from your chin and he sighed. “Hurry before you’re late,” was all he said before turning around and walking back towards the dorm, leaving you in a post-kiss daze.

You made it to your class, albeit, late because your mind kept trying to make sense of the kiss that you’d accidentally passed the door to your classroom...twice. Of course, you had kissed Katsuki before. Kissing him on the lips wasn't necessarily a rare occurrence either. But never had he incited a kiss on his own—and in public? Well, that wasn't even in the realm of possibility before. No matter how many times you tried to convince yourself it wasn't strange, you couldn't help but feel suspicious.

As you dissociated from your lecture your brain kept replaying the kiss, searching for a reason to why the kiss felt different. No, it didn't feel different. It felt strange. But it only felt strange because something about it felt familiar. It shouldn't have felt familiar. If a guy initiates a kiss with you for the first time it shouldn't feel familiar. Why did it feel familiar?

And then it hit you. He licked his lips.

He licked his lips!

Your brain switched to your kiss with Shouto earlier in the day. After you kissed him he had licked his lips too. You thought it was weird then, but didn't think twice about it. Now you were thinking twice.

‘I’m just being crazy,’ you thought.

In what way could the kisses be related? What? Because they both happened to lick their lips afterwards? So what? That didn’t mean anything. It meant nothing. You were sure of it...

Almost.

You shook the thoughts from your head, refocusing your attention back to your professor at the front of the room. After class, you made your way back to the dorms to get started on your studies while Mina and Jiro were out. The sun had long since set, and you were two hours deep in frustration preparing for your Hero Physics midterm when a knock came from the door.

You welcomed the distraction, considering you were about to re-read the same question for the fifth time with no progress of understanding it anytime soon, and if you read it again without a miraculous conclusion, you were going to bash your brains in with your laptop.

Needless to say, when you opened the door to see Izuku standing in the hall, you welcomed him with open arms.

“Hey!” You smiled.

Izuku looked you up and down. You were still wearing Katsuki’s hoodie, but you had switched out your dress for pajama pants and fuzzy socks. It was subtle, practically unnoticeable, but the slightest crease formed in-between his eyebrows when he noticed.

“Is that Kaachan’s hoodie?” He asked.

You looked down at your torso, as if you had forgotten you were wearing anything at all. “Oh, yeah,” you said. “I spilled soda all over my dress earlier while I was with him and he let me borrow it. Honestly, I’m thinking about keeping it at this point. I was supposed to return it as soon as I got back but it’s freezing in here because the thermostat is stuck at sixty-nine degrees and this hoodie is so much warmer than any of mine.”

“You should really call maintenance to fix that.” He brushed past you, entering your room and plopping his backpack on the floor by your desk. You closed the door behind him and crossed your arms.

“What's this?” He asked, picking up your notebook.

“My suicide note.”

Izuku chuckled, looking over your notes and at the assignment on your computer. “I took Hero Physics last semester,” he told you. “I can help you if you want.”

“If you want to dedicate your time to a hopeless cause, be my guest.”

And he did. He took a seat next to you at your desk and spent the next hour tutoring you on Hero Physics by walking you through questions like ‘Find the velocity of this speed-type hero’ and what-not. Surprisingly, it wasn't long into your session that you began to understand the words on your screen. You didn't suddenly become Einstein or anything, but at some point you started to work your way through them on your own with few mistakes. The assignment you had spent two hours slowly killing yourself over was completed in one with the help of your freckled friend.

“I think you’re aiming for the wrong profession, Izuku,” you tell him. “Schools need more teachers.”

“Then schools should pay them more.”

You tried to snort back your laughter, ultimately failing, causing Izuku to laugh along with you.

“Want a drink?” You asked, standing to your feet.

“Sure.” He nodded. You left him at your desk and came back with two Arizona teas from your mini fridge to share with him.

“You never mentioned why you stopped by unannounced,” you said as you took a sip. “Not that you’re ever unwelcome.”

“Oh,” he smiled. “I guess I just wanted to see you.”

You looked down at your hands wrapped around the can, unable to meet his eyes. Izuku always managed to make you blush. You weren't sure if he meant to or not. Either way, he was completely oblivious to the effect he had on you.

“Well thank you. It’s always nice to see you.”

Similarly, Izuku blushed as well, his cheeks turning pale red. His eyes shifted to the clock on your desk. “I should probably go,” he said, not really wanting to go. “It’s getting late.”

“Oh, right.” You both stood to your feet and Izuku gathered his things. You walked him to the door, leisurely leaning against the doorframe as he exited into the hall. “Think you can keep tutoring me?”

Izuku turned around.

“I still need to pass finals,” you said.

He nodded. “Then I'll make sure you pass finals.”

Grinning, you closed the space between you, mindlessly reaching to place a kiss on his cheek when you were reminded of the other kisses you'd shared with Shouto and Katsuki. A thought in the back of your mind spurred from your suspicions—a thought that quickly turned into an idea. At the last second, you acted on your impulse to b-line for his lips, catching you both off guard. You stuck with it, pressing your lips against his harder than you intended. The action stunned him, but it didn't take him longer than a second to embrace it.

It was just a kiss. Not unlike the many kisses you often shared with the others. Not unlike the kisses you've given him before. It was just a simple peck...until it wasn't.

You pulled away, prepared to give him your thanks for helping you with your studies. But, you never got the chance. Your words were silenced by his lips chasing after yours. Your breath hitched in your throat as your back pressed against the door frame. His hands cupped your cheeks and your lips moved in sync, his tongue daring to swipe across your lips. In the heat of the moment, your mouth nearly opened for him, but he pulled away just as your lips began to part, and you opened your eyes to meet dark green irises peering down at your flushen face.

Your eyes flickered down to his pink lips, now reddened and somewhat swollen. You watched in disbelief as—just like the others—he, too, licked his lips.

“Watermelon,” he said lowly. Your chest heaved, your words escaping you. Izuku stepped back, his usual sickeningly sweet smile staring back at you as if nothing happened.

“We should split some watermelon,” he said. “The next time we study together. That’s my asking rate.”

You nodded hazily. “Okay.”

With that, he said goodbye and left you standing in the doorway to your room dumbfounded.

Yeah.

Something definitely was up.
