Car(ing) Tickles
A/N: I watched the "future" episode of BNHA and how could I not notice the special manufacture of Bakugou's backseat? Well, the three of them in one car was just too good to be left out.
Words: 3,229 words under the cut
The inside of Bakugou’s car was warmer than Midoriya expected. Not just temperature-wise, but also the seats. He shifted slightly in the back, then stilled. “…Whoa.” He sank, actually sank. The soft cushion gave way under him in this slow, almost ridiculous way, like it was hugging him back.
He leaned his head against the side, his shoulders relaxing before he even noticed it happening. “Your car is really comfortable, Kacchan,” he said, a little softer than usual. “Tch. Obviously,” Bakugou replied from the driver’s seat, “didn’t buy it to be uncomfortable.”
From the passenger seat, Kirishima twisted around halfway, resting his arm over the backrest as he looked at Midoriya. “Dude, you look super comfy back there,” he laughed. “Yeah, it’s surprisingly fluffy,” Midoriya commented, then shifted again. He sank even deeper. “…It feels like floating on a cloud...”
Kirishima grinned. “Careful, you might not make it to the reunion. We’ll have to peel you out of the seat.” “Don’t joke about that,” Bakugou muttered, “if he gets stuck, I’m leaving him.” Midoriya smiled faintly, already relaxed in a way he hadn’t been all week.
They were on their way to see everyone again- properly, with no emergencies, no missions - just a reunion - and for once, things felt… easy. The car hummed quietly for a while, city lights slid across the windows in soft streaks. For a moment, it almost felt peaceful, then Kirishima turned in his seat slightly.
“Still kinda wild, huh?” the redhead said, glancing between the road and Midoriya. “Todoroki making number two.” Midoriya nodded immediately. “Yeah… but it makes sense. He’s been working really hard and his control’s gotten so much better since U.A. - like, remember during training camp when-”
“Oh man,” Kirishima laughed, cutting in, “training camp was chaos.” Midoriya perked up a bit more. “It really was! Actually- Kirishima, didn’t you-” The redhead titled his head slightly. “Didn’t I what?” Midoriya hesitated for a moment. Then smiled as he remembered. “You… ehm You got really flustered that one time.” Kirishima blinked. “Huh, did I?”
“There was that time with the training weights and Mina,” Midoriya added, a little more confidently now, “when she teased you about-” “HEY,” Kirishima cut in quickly, pointing at him, “watch it, that was ages ago...” he mumbled, a bit flustered now. Midoriya froze for a second, then laughed a little. “I’m just saying! You turned really red-” “I did not!”
“You did! And you kept trying to act normal afterwards, but it was really obvious that-” Kirishima turned fully in his seat now, grin sharp but just slightly strained. “Midoriya, come one man, that’s not very manly...” Midoriya, now fully in the memory, didn’t stop. “And then Kaminari made it worse because he kept bringing it up, and you just-”
“Midoriya,” Kirishima repeated, slower this time, “please, I’m warning you!” Bakugou’s eyes narrowed slightly in the rearview mirror. “Oi, Deku.” However, the green bean was still muttering, now half-laughing to himself at his own recollections, completely unaware of the warning tone in Kirishima’s voice - much to the redhead’s dismay.
“And then during that same week, there was actually that other time where you-” “Alright, that’s it,” Kirishima said suddenly, “you asked for it!” Midoriya looked up, still half-muttering. “Huh? Asked for it…?” Kirishima’s grin turned sharper at the edges.
“Bringing up that old story about my- *cough* anyways, you’re in trouble now Midoriya, because I also remember something from training camp… the pull-up bar incident…” Kirishima teased, wiggling a hand at him. That made Midoriya pause. Then blink. Then he looked genuinely confused. “…EH! You’re g-g-gonna t-tickle me?”
Bakugou sighed loudly. “Don’t start anything in my car!” The car slowed slightly at a red light and came to a stop. Kirishima stared at him. “Bakugou?” Bakugou exhaled through his nose as he side-eyed his friend. “Don’t you dare-”
But there was a fire burning in his friend’s ruby eyes - nothing could stop him now, not his seatbelt and not the blonde’s warning stare at him. Kirishima unbuckled his seatbelt. “I warned him.” “Shitty Hair- HEY! I said- argh- Kirishima!”
“Don’t worry, I’m not ruining your precious car interior, Bakugou,” Kirishima said as he leaned down, tugging his shoes loose quickly and kicking them off near the passenger footwell. Then he straightened, flexing his toes once against the floor. Midoriya blinked. “Wait- What?” “See? Not gonna mess up your car,” Kirishima said smiling.
“That’s not even- *sigh* I swear to god,” Bakugou growled, “if you even think about-” But Kirishima was already moving. Before Midoriya could even process what was happening, he turned himself around in one smooth motion, and climbed carefully over the center console into the backseat like it was the most normal thing in the world.
Midoriya’s eyes widened in surprise. “Wait- K-Kirishima?” The redhead clicked his seatbelt into the backseat latch without even looking, then he looked at Midoriya, grinned, and launched forward. The green-haired barely had time to inhale before Kirishima’s hands found his flanks, eagerly scribbling over them. The reaction was instant.
Midoriya’s entire body jolted the moment his hands landed at his sides, fingers digging in just enough to make him gasp. “EhEhe! NoHOHoHOHo!” Midoriya whined, trying to curl away, but the soft structure of the backseat betrayed him completely. Every time he tried to twist away, he just sank deeper into the cushion, his laughter spilling out uncontrollably.
“You had your chance!” Kirishima laughed as his fingers danced up and down his sides in quick, relentless motions that made Midoriya squirm helplessly. “AhH! BuhuHut iHiht- ehEhehh- iHit tihihickles!” “No kidding,” Kirishima shot back, grinning as he leaned closer, keeping him pinned more by presence than force.
“Hahaha- w-wait! I cahaHhan’t!” “Yeah, I can see that,” Kirishima laughed, already enjoying this way too much. Bakugou’s voice cut in from the front. “HEY! Are you seriously doing this right now?! In my car?!” Kirishima didn’t even look up. “He started it!”
“I did NOT start- EEK!” Midoriya’s protest dissolved into laughter as Kirishima shifted his grip, fingers now targeting his lower ribs in quick, rhythmic bursts that made it impossible to catch his breath properly. “D-Dehahahah- K-Kirishima-kun stoohohop!” Bakugou’s eye twitched.
“I am seconds away from throwing both of you out.” But even as he said it, his voice wasn’t as sharp as before. His eyes wandered to the rearview mirror, despite himself, and he could see it clearly: Midoriya laughing too hard to even sit upright, Kirishima fully leaning into the moment, grinning like an idiot while continuing his relentless tickle assault.
Something about it - that annoying, loud, stupidly familiar laughter - made Bakugou’s mouth twitch upward before he could stop it. “Tch.” Kirishima looked up in that very moment, not even stopping his ticklish assault, and their eyes met. His smirked back at the other, as if catching him red-handed.
The blonde quickly looked away, focusing back on the road again, a faint blush creeping up to his ears. The light finally turned green and Bakugou stepped on the gas. However, the laughing didn't stop, it only got more intensive. Bakugou played with the thought to switch on the radio, but that would've been more annoying.
“Keep it quiet, someone tries to drive he-” “Pfft- aHAHAHAHAhahAHAH!” Midoriya’s laughter cut him off entirely, bright and uncontrollable as Kirishima suddenly switched spots, fingers slipping up toward his armpits in quick, teasing bursts. “Hey! Don’t ignore me, I said-” “NO! NOHOHOT THERE!” “Oh, that’s a bad spot?” Kirishima’s grin widened. “Good to know~”
Midoriya tried to grab his wrists, but his hands kept missing, his coordination completely gone as he laughed. “K-Kirishima plehehease! I’m soHohorry!” “You were talking big a minute ago,” Kirishima teased, scribbling faster. “I- HAHA I wasn’t!” Bakugou groaned audibly for them to hear. The redhead looked up again, trying to give the other an apologizing look.
"Hehe sorry Bakugou, it's not my fault Midoriya is so ticklish~" Using the momentum of the red-haired’s distraction, Midoriya managed to somehow catch Kirishima’s side, immediately squeezing it. Kirishima jerked. “H-HEY!” he giggled. Midoriya, still laughing, took advantage of it right away, poking into his side with clumsy but determined fingers. “G-GoHot you!”
“OH, you wanna go?!” Kirishima shot back, laughing, as he immediately dove back in, tickling him harder. Both of them laughing, both trying to tickle the other, though Kirishima clearly had the upper hand - better reach, better control, and Midoriya still half-trapped in the stupidly soft seat. “HaAhhaha! K-Kirishima!”
The redhead didn't even need to use his Quirk to hold the upper hand - well, he wouldn't have done so anyways. For once, it was unmanly to cheat and for second Bakugou would kill him for sure, if he would use his Hardening Quirk inside his car. Bakugou clicked his tongue again, his patience reaching his climax.
“Shut up,” he muttered, glancing up at the mirror again. “EheHEHE MidoriHiya, you started t-thiHis!” “I dihihid not!” Bakugou slammed his palm lightly against the steering wheel. “SHUT UP, BOTH OF YOU!” Neither of them did.
Midoriya’s laughter came in breathless bursts now, his attempts to fight back getting weaker as Kirishima kept finding those same spots over and over again, like he was memorizing them on the fly, fingers now wiggling and poking his stomach. “Okay- Okay! StHohop- I’m- ahAhahH I’m soOHohorrry!” “You already tried that,” Kirishima laughed.
“Thihihis time I mean it!” “Oh~ So you were lying back there, ehh~” “NOhoHOHHOH! AhAHAHAHHH!” They reached another red light an Bakugou executed an unnecessarily hard emergency stop. The interior of the car finally fell silent. He turned around and stared at the two of them, an - unknown to him - almost jealous-looking expression on his face.
“If I hear one more laugh or giggle from either of you, I’m leaving you on the side of the road, for real this time,” he said flatly, before facing the street again. Kirishima finally eased up, hands slowing, then stopping entirely. "Sorry, Bakugou... I got a bit too excited," he mumbled, rubbing the back of his neck.
Midoriya slumped back fully into the seat, chest rising and falling, a breathless laugh still escaping him every now and then. "Kacchan I..." Midoriya didn't continue, unsure what to say. From the front, Bakugou glanced at the mirror one more time, sighing. “…Dumbasses, try to keep it quite at least, okay?” But he didn’t sound annoyed. Not really.
Kirishima grinned, giving him a thumbs up. “You got it, bro~” Midoriya huffed, still smiling despite himself, visibly relaxed. “Of course, Kacchan~” The two giggled to themselves, exchanging small pokes and squeezes for the rest of the drive, unaware of the other's gaze as he watched his two friends continues little tickly squirrel at the back seat.
...
Bonus
The engine cut off with a sharp, final click. Silence settled inside the car. Bakugou kept his hands on the wheel for a second longer than necessary, exhaling slowly through his nose like he was trying very hard not to say something. He only managed to hold back for a few seconds. “You two are annoying as hell.”
Midoriya, still a little slumped into the backseat, let out a quiet, leftover breath of laughter while Kirishima snorted beside him. “C’mon, it wasn’t that bad,” Kirishima said, “and don’t think I didn’t notice you looking at us,” he teased. Bakugou turned his head just enough to glare at them over his shoulder. “You were screaming.”
“I wasn’t screaming,” Midoriya protested weakly. “You absolutely were,” Bakugou shot back, “both of you. The whole damn drive!” Kirishima stretched his arms behind his head, completely unbothered by his friend’s words. “Sounds like someone’s jealous he wasn’t having fun.” Bakugou’s eye twitched. “I don’t need that kind of ‘fun’,” he snarled.
There was a slight pause. Then Kirishima slowly turned his head. Midoriya did the same. They looked at each other and something unspoken passed between them almost instantly. Bakugou noticed. “…Don’t.” The redhead’s grin spread first, Midoriya’s followed - smaller, but definitely there. “Don’t what, Ka-tsu-ki?” Kirishima asked innocently.
Bakugou narrowed his eyes. “I know that look.” “You’re imagining things,” Midoriya said, which already sounded like a lie. Bakugou opened his door. “I’m getting out.” He didn’t make it. Two hands grabbed him at once and the door closed again. “HEY?!”
Kirishima hooked an arm around his middle from behind, pulling him backward, while Midoriya grabbed his arm to keep him from bracing against the door. Bakugou twisted immediately, but the angle was all wrong - half-turned in his seat, caught off-balance - and then he was dragged back.
“WHAT THE HELL, SHITY HAIR?!” Kirishima shifted fast, sitting back properly and pulling Bakugou with him, until Bakugou ended up in his lap. “Are you serious right now?!” Bakugou snapped, trying to push himself up, but Kirishima locked his arms loosely around him, keeping him in place - not tight, just enough so that he couldn’t break free.
“We thought you might need some tickles as well,” Kirishima said brightly, a smug grin on his face. Midoriya smiled at his childhood friend. “…S-Sorry, Kacchan.” “Deku, don’t you dare-” Kirishima’s stroke first, fingers digging into the blonde’s side. Bakugou jerked. A sharp inhale- then a short, startled sound slipped out before he could stop it. “NnGn!”
He cursed on the inside, by his body’s betrayal. “Oh?” The redhead’s grin widened instantly. “No way, Great Explosion Murder God Dynamight is still as ticklish as ever, awesome~” Bakugou immediately clamped his mouth shut, glaring. “Try it again and I’ll-” Kirishima did. Both hands this time, fingers pressing and scribbling into his sides, right above his hips.
Bakugou’s shoulders tensed hard. “Tch-! KiHirishi- n-noHOho!” But his body reacted anyway - jerking again, breath hitching as he tried to twist out of Kirishima’s hold. “Stay still,” Kirishima laughed, adjusting his grip just enough to keep him from slipping away, “you know you’re gonna like it, so just enjoy it~” he teased. “Huh! F-FuUHuck ohohoff!”
Bakugou was doing his best to break free from him, but the tickling made it really difficult to gather his strength. “LehehHt gohoo of me, damn it!” he cursed, feeling his face heating up from embarrassment. Midoriya shifted closer. “…Kirishima? Ehm, where-” “Shoes,” Kirishima said immediately, not even looking at him, “take ‘em off.” Bakugou froze. “…Don’t.”
Fuck, he was so damn screwed. Midoriya hesitated for only a second. Then reached down. “Kacchan, I- uh-” “Deku!” That tone should’ve stopped him - it didn’t. He grabbed Bakugou’s kicking leg in an armlock and slipped his shoe off, revealing a black wiggling sock, before letting it fall to the floormat. Kirishima laughed under his breath. “Too late now.”
Bakugou tried to jerk his legs back, but between the cramped space, Kirishima holding him in place, and the way he was half-sitting, half-leaning he didn’t get far, and before he could stop it, Midoriya had pulled off his other shoe as well, keeping the foot in a strong hold. “Don’t you-” Bakugou began just as Midoriya’s fingers brushed against the fabric of his sock.
Bakugou sucked in a breath. “DeHehku, I swear-” he cursed, the first reactions already bubbling out of him. Midoriya wiggled his fingers and Bakugou snorted. His entire body jolted as his foot twitched hard, pressing back into the redhead instinctively. “Pfft- FuHuhck- nohoHOHOHO! HAHAHaHAhH!” Kirishima lost it immediately. “No way- Did you just?!”
“ShuHUhut uHUhup! AHHaHAHAHAHH!” Bakugou laughed. Midoriya blinked, surprised- then smiled, just a little. “…Kacchan, you’re still really ticklish, I’m glad.” “I am noHOhot and d-doHoHohon’t be happy about iHihiit!” Midoriya tried again, slower this time. His fingers dragged lightly over the sole, sliding over his arch and the hell.
Bakugou bit down hard on whatever sound tried to escape, but it came out anyway, sharp and uneven. “NnGhHH!” His leg kicked. Kirishima tightened his hold just enough to keep him from slipping forward, laughing as he continued working at his sides. “Man, you’re way worse than Midoriya!” “SceeHEhew yohoOu! BoOHohth of you!”
Out of anger, he tried to kick Midoriya with his still free leg in the back, but ended up having it been caught in his armlock as well, and he cursed innerly for his own stupidity. Midoriya’s fingers moved more confidently, tracing little lines, then quick scribbles, right across the most sensitive spots of his soles - even through the fabric, it was enough.
Bakugou’s composure cracked. A sharp exhale turned into a short, choked laugh. Then another. “HahahAh st-stoHOhop!” “Say please,” Kirishima teased. “GHoo. ToHohoo. H-HehEhehll!” “Suit yourself~” Kirishima immediately dug his fingers in harder at his sides, fingers pressing softly into the flanks of his blonde friend.
Bakugou jerked back against his chest, a real laugh breaking through this time - loud, unguarded, completely against his will. Midoriya froze for a second - he didn’t hear that often. A warm smiled crossed his face. Then, carefully, he kept going. “K-Kacchan, your reactions are really- um adorable~”
Bakugou kicked again as his feet was tickled more insistently, laughter spilling out between clenched teeth. “I saHahid shuHut up DeHek- IzuHuhuku!” Bakugou laughed and him calling his name didn’t go unnoticed by the other. Kirishima leaned his chin briefly against Bakugou’s shoulder, grinning as he continued. “Dude, you’re so done.” “I wiHiill kiHill yoHou!”
“You can try,” Kirishima laughed. The car filled with noise again - laughter, protests, half-formed threats. Bakugou twisted, tried to grab Kirishima’s wrists, tried to yank his feet away, but every movement just made it worse, opening him up to more ticklish spots, more reactions he couldn’t control.
Midoriya’s fingers slipped under the edge of his right sock just slightly, wiggling along the bare ankle of the wiggling captee while keeping them in a strong hold, and Bakugou lost it. A sharp, unfiltered burst of laughter broke out of him, head tipping back against Kirishima’s shoulder before he could stop it. “No! Stohohop! NoHOhot thAHAht!” he almost pleaded.
“Got him,” Kirishima said, way too pleased. It went on like that - longer than it probably should have. Long enough for Bakugou’s threats to lose their edge. Long enough for his resistance to turn into desperate squirming. Long enough for both Midoriya and Kirishima to be laughing just as hard as he was.
Eventually, Kirishima slowed first. “Alright, alright,” he said, easing up, “I think we made the others wait long enough…” Midoriya followed, pulling his hands back, sheepishly looking to the side. Bakugou slumped forward immediately, breathing harder than he’d ever admit, face flushed bright red. “…I hate both of you,” he pouted, crossing his arms
“Yeah, yeah,” Kirishima said easily, petting his head. Midoriya smiled a little, still catching his breath. “Sorry, Kacchan…” Bakugou shot him a glare that had absolutely no bite left in it.
…A little later…
The three of them stepped into the venue. Voices, laughter, familiar faces - it all hit them at once. “Yo!” Kaminari spotted them immediately, jogging over with a grin. Then he stopped, looked at Bakugou, and paused. “…Why are you so damn red?” he asked, eyebrows raising. “Did you run here or something?”
Bakugou’s expression darkened instantly. “Shut up, Dunce Face,” he snarled and stomped away, leaving the three of them back. Kaminari looked questioning at the other two. “Did I say something wrong?” Kirishima snorted. Midoriya looked away, trying- and failing not to smile. They had much to explain…
