5 Times Class 1-A Almost Found out About Kirishima and Deku's Relationship and the 1 Time They Did

Summary:

Just a little fic I wrote where Kirishima and Deku are keeping their relationship a secret from the rest of Class 1-A. Unfortunately for them, their classmates are incredibly nosy...

Kirishima let out a breathy sigh as he quietly shifted to a slightly more comfortable position, taking special care to not wake the smaller green haired boy fast asleep and laying across Kirishima’s chest. The sun had started rising and the room was enveloped in the welcoming glow of the breaking dawn. Gently, Kirishima carded his fingers through his boyfriend’s soft curly locks. A content sigh escaped Izuku’s lazily parted lips at the soothing sensation of Kirishima’s fingers massaging his scalp. Shifting his body closer to the red head, he snuggled closer to his boyfriend’s bare chest, chasing his warmth as his eyes fluttered open sleepily. Peering up a bit, Izuku caught the other’s gaze almost immediately and felt his cheeks heat up when his tired emerald orbs were met with bright and alert ruby ones. A smile grew on Kirishima’s face at the realization that his adorable boyfriend beneath him had finally awoken from his slumber. A look of amusement crossed his face as Izuku’s freckle-littered cheeks were dusted with a pink blush.

Notes:

I love this rarepair so so much!! Originally, this fic was meant to be one long chapter but it ended up being a bit longer than I had anticipated so I'm just going to post each 'prompt' as a separate chapter over the next little while. :)

(See the end of the work for more notes.)

Chapter Text

Kirishima let out a breathy sigh as he quietly shifted to a slightly more comfortable position, taking special care to not wake the smaller green haired boy fast asleep and laying across Kirishima’s chest. The sun had started rising and the room was enveloped in the welcoming glow of the breaking dawn. Gently, Kirishima carded his fingers through his boyfriend’s soft curly locks. A content sigh escaped Izuku’s lazily parted lips at the soothing sensation of Kirishima’s fingers massaging his scalp. Shifting his body closer to the red head, he snuggled closer to his boyfriend’s bare chest, chasing his warmth as his eyes fluttered open sleepily. Peering up a bit, Izuku caught the other’s gaze almost immediately and felt his cheeks heat up when his tired emerald orbs were met with bright and alert ruby ones. A smile grew on Kirishima’s face at the realization that his adorable boyfriend beneath him had finally awoken from his slumber. A look of amusement crossed his face as Izuku’s freckle-littered cheeks were dusted with a pink blush.

Deku quickly averted his gaze from Kirishima’s, flushing a brighter shade of red at his lover’s brilliant smile. His heart rate quickened a bit as he buried his face against Kirishima’s bare chest with an embarrassed squeak. “Please don’t tell me you were watching me sleep, Kiri, that’s so embarrassing.” Izuku mumbled against Kirishima’s warm skin where his face was pressed firmly, his lips brushing the soft skin lightly as he spoke.

Chuckling lowly, Kirishima spoke in an amused tone of voice, “Don’t worry, Zuku, it wasn’t long at all. And it’s nothing to be embarrassed about, you just look so adorable when you’re sleeping. You look so peaceful and your nose scrunches up a little bit at the top. It’s adorable, but in an entirely manly way of course.”

At the red head’s words, Izuku slowly emerged from his hiding place to peer up at the taller of the two with a bright smile. Eijirou loved the slightly smaller boy’s smile more than anything else; he was almost certain that the freckled boy could warm even the coldest of hearts with that breathtaking smile. Practically everything Kirishima’s boyfriend did resulted in an immense feeling of endearment to bubble in his chest and in most cases, he couldn’t hold back from enveloping the other in a tight hug and peppering his face with kisses, usually attempting to peck each and every freckle that delicately painted Izuku’s pale face. With a smirk, Kirishima made an impressive display of his strength by flipping Izuku so that he was lying face up on the mattress with Kirishima hovering over the green-haired beauty. Kirishima’s arms were planted firmly on either side of Izuku’s frame, their matching bare chests close but not touching yet still radiating heat between them. Midoriya found himself greatly appreciating the significant height difference between himself and his boyfriend in that particular moment as he felt his stomach twist and turn at the sight of Kirishima’s larger frame hovering above him. Izuku’s bright green eyes were wide with surprise and he scrunched his nose up as a light giggle tumbled from his soft lips. Kirishima bent to meet the freckled bridge of Deku’s nose with a feather-light brush of his lips, causing another symphony of amused giggles to meet his ears. Slowly, Kirishima began to pepper delicate kisses along the rest of Izuku’s face. He trailed his lips across the other’s beautiful features; the little crinkle between his eyebrows, across his forehead, along the freckles decorating his rosy cheeks, and finally he reached his lover’s plump, pink lips. Izuku was humming softly beneath the red-haired man through his lazy ministrations and had at some point extended both arms to reach up to his boyfriend’s strong body; one hand was tangled in Kirishima’s bright red hair, the other gripping his hip gently. Eijirou smiled goofily before he finally pressed his lips to Izuku’s in a slightly more fervid manner than the previous gentle touches. He lowered his body slowly, so that the two were pressed together at practically every point of contact possible. Deku hummed against Kirishima’s lips and allowed the other to deepen the kiss slightly as he slid a up to Izuku’s face, cradling the man’s head gently. Izuku leaned into his boyfriend’s hold and whined as Kirishima pulled his lips away from Izuku’s.

Letting out a quiet groan, Izuku moved a hand to caress Kirishima’s hair with a light touch, brushing the red, messy bangs from the other’s eyes. “That’s certainly a nice way to wake me up.” Izuku let out another brilliant smile as he spoke, his voice dripping with affection for the red-haired figure above him.

Eijirou let out an amused chuckle before pressing his forehead lower so it met Izuku’s own. Refusing to move from the comfortable position, Eijirou spoke in a low and almost solemn tone, “I’ll say it was nice, then again, I think anything involving you half naked beneath me is above and beyond the description of ‘nice.’” Deku let out an undignified squeak at Kirishima’s words but didn’t say anything. Kirishima pulled his forehead from where it was resting against Izuku’s before continuing his previous thought, “But, we do have to get up now, Zu.”

At the suggested prospect of Kirishima attempting to remove his warm body away from where he was cozily pressed against Izuku’s own, drew a disheartened whine from his throat. Reaching upward, he wrapped his arms around Eijirou’s neck and pulled him down, turning his body in the process. He successfully tugged his boyfriend’s larger body to be flush against his own and giggled as he brushed their noses together. The two young men were laying face to face, both on their sides; Midoriya’s arms remained tied tightly around Eijirou’s neck while the other rested his hand on Izuku’s hip. Kirishima let out an amused huff as he flashed his teeth with a bright smile. Izuku peered up at him with those irresistible emerald eyes that had a mischievous glint hiding beneath the surface. He batted his eyelashes several times in feigned innocence as he slowly dragged his hands down the red-haired man’s chest in a tantalizingly slow and teasing manner.

Kirishima opened his mouth to speak but struggled to find the words as he found himself distracted by his lover’s strong yet gently touch. Gasping slightly as the green-haired boy’s fingertips gently brushed a particularly ticklish section of his abdomen, Kirishima jolted underneath his touch and shot an accusatory glare in the other’s direction. “Zuku, baby, you better not- ah!” He shouted in surprise as Deku’s fingers began fluttering across the red head’s defined abs. A litany of laughter spilled from Kirishima’s mouth as he squirmed on the small dormitory bed trying to escape his boyfriend’s hold. Before Eijirou could writhe away from Izuku’s merciless fingers, the other was straddling his hips and continuing to pull a string of giggles from his lips that were practically music to Izuku’s ear.

Suddenly, a loud pounding on the door startled the two from their position. Izuku ceased his attack and sat upright immediately with a terrified look of realization crossing his face as the familiar voice of his angry and impatient childhood friend, Katsuki Bakugou, or as Midoriya had grown accustomed to calling him, Kacchan, came booming through the door. “Hey, Shitty Hair, hurry up and get out here so we can leave before I blow the door down and drag you out myself!”

Izuku squeaked pitifully at that notion and immediately smacked a hand over his mouth with a panic-stricken look. Kirishima ran a soothing hand along his boyfriend’s bare arm as a comforting gesture which didn’t quite reach his eyes. Despite the effort to comfort his clearly panicking boyfriend, he was already scrambling from his position on the bed and rushing around the small dorm room. There was a flurry of clothes as the two managed to shed their pajama pants and throw on their uniforms as quickly as humanly possible.

Izuku giggled softly as he watched Kirishima huff out a frustrated sigh as he tied his hair into a messy bun using a black scrunchie. “I love your hair like that Ei!” Izuku whispered as he swiftly grabbed the other by the sleeve before tugging him to plant a gentle kiss on the surprised redhead’s slightly parted lips.

A bright red blush dusted his boyfriend’s cheeks as he pulled his lips from the shorter man’s soft ones and spoke with a whine, “I don’t want to go to class today. I wish I could just spend the whole day with you.”

Before Deku could reply, Bakugou’s hostile voice was booming through the door, “Alright, Hair for Brains, you’ve got about 5 seconds before I blow this door down.”

With a chuckle, Kirishima shook his head as he headed for the door. Izuku inhaled shakily as he fiddled with the hem of his uniform jacket, watching as the door swung open to reveal his very angry-looking childhood friend. The recently exposed hallway revealed Kirishima’s good friend angrily shouting a string of curse words at the redhead for expecting him to wait for such an excessive amount of time (despite the fact that it had only been a minute or two since he had knocked the first time). Suddenly, the angry blonde’s heated facial expression melted to one of slight confusion and then back to the seething anger from before.

“What the fuck is that dumb nerd doing in your room, Shitty Hair?” Bakugou practically spat the venomous words as a sneer rose to his face.

Despite the fact that Izuku and Kirishima had been dating for almost a year now, they had mutually agreed early in the relationship to keep the fact that they were together to themselves until they all graduated. They had decided it was best due to several factors such as: Bakugou’s hostility towards Deku, Todoroki’s obvious crush on Izuku (which he hadn’t noticed until his redhead boyfriend jealously begged him to stop studying with his dual-haired teen alone in the other’s dorm room), and most importantly, their classmates’ collective and unstoppable urge to gossip relentlessly about anyone and everyone.

Deku’s eyes widened at Katsuki’s angry words and immediately shook his head aggressively before attempting to convince the blonde that nothing out of the ordinary was going on. “Kacchan, I-I was just uh- you know…” He paused for a moment before he caught a glance of Kirishima’s pleading face. “I JUST HAD TO GRAB MY TEXTBOOK BECAUSE K-KIRISHIMA-KUN ASKED TO BORROW IT!” He shouted out and scrunched his face up a little as he recognized the familiar sensation of anxiety bubbling in his chest.

Bakugou scoffed loudly before rolling his eyes, “Whatever Shitty Deku, let’s go Kirishima.” He muttered, shocking the two anxious teenagers by the use of the redhead’s name.

Deku squeaked quietly before he quickly shuffled out of the dorm and waved at the odd duo before retreating hastily and nervously stammering out, “B-Bye, Kacchan! See you later, Kirishima-kun!” Letting out a sigh of relief, he scurried down the hallway, hands shaking slightly at the realization that Kacchan would have blown him sky high had he realized what he was actually doing in Kirishima’s room.
