Shirtless (My Hero Academia)
Shipping: Kirishima x Bakugou (KiriBaku)
Summary: Kiri keeps stealing Bakugou's shirts, but when Bakugou decides enough is enough, Kiri sees a golden opportunity to get a little more intimate with his boyfriend.
A/N: My very first KiriBaku shipping fic! I've wanted to try my hand at one of these for a long time, since I know it's a popular shipping, and their dynamic is really great. Hopefully I did okay with my first attempt! Enjoy!
Shoutout to @thatbigdyke29 for the "stealing each other's shirts" suggestion!

“Is that my shirt you’re wearing?” Kirishima asked incredulously, staring at the image of Bakugou in a baby blue button-down. He’d journeyed to his boyfriend’s dorm room after getting a text asking if he wanted to hang out, and this was the last thing he’d expected to see.
“Yeah, so?” Bakugou put his phone away but made no move to sit up from his position comfortably lying on his pillow. “You keep stealing mine. I thought I’d return the favor.”
Kiri blushed. As it happened, he was wearing one of Bakugou’s t-shirts right now. He couldn’t deny it if he wanted to. “I, uh…suppose that’s fair.”
“Why do you keep stealing mine anyway? I saw your closet. You have plenty of clothes.” The blonde lifted his head toward Kiri, his eyes widening when he saw his favorite skull t-shirt on his boyfriend’s chest. “And why that one?! You know that’s my favorite!”
“Stealing each other’s clothes is a couples thing, Kats,” Kiri replied, smiling as he made his way over to the bed where Bakugou was now sitting up. “It’s supposed to be cute.”
Bakugou gritted his teeth. “It is cute,” he admitted begrudgingly, “as long as you’re not wearing my favorite. Take it off!”
Kiri laughed. “Whoa, take me to dinner first!”
“I put up with a lot of your stupid nonsense, but this is my favorite t-shirt. I don’t want you ripping it up if we get called out to fight a villain or something. Off!”
“Fine, all right. I’ll take it off.” Kiri grabbed at the hem of the black shirt and pulled it over his head. “Happy? But now I feel weird being the only one without a shirt.”
Bakugou snatched his clothes back from his boyfriend. “That’s your problem.”
“You should take yours off, too.” Kiri smirked, wiggling his brows suggestively. The blonde huffed in irritation, but reached to undo the top button anyway.
As soon as the tip of his boyfriend’s chest was visible, Kiri snatched up his wrists, stopping him from going any further. Bakugou looked up at him. “The heck? You’re the one who told me to—”
“Let me…” Kiri gently pushed his hands away, releasing him. “Let me do it.” Then, without waiting for permission, he reached to undo the second button, then the third, then the fourth.
Bakugou was frozen to the spot, heart hammering in his chest. This situation had shifted moods incredibly quickly. Now rather than frustrated, he was transfixed, unable to take his eyes off the redhead, especially when he knelt down to get to the last few buttons on the shirt. The way Kiri looked up at him was doing things to his insides he still wasn’t used to yet.
“There,” Kiri murmured, running his hands up Bakugou’s chest to his shoulders, gently pushing the fabric of his own shirt away from the blonde. “Much better.”
“Ei…” Bakugou managed, dutifully allowing Kiri to remove the shirt completely and toss it to the ground, forgotten.
“What’s the matter?” Kiri teased, standing up again and pressing a kiss to Bakugou’s jaw along the way. “Don’t tell me you’re getting flustered~”
“N-No! Of course not, idiot…” Bakugou protested, though it didn’t sound very convincing. He let the redhead push him back onto his mattress, climbing up to hover over him teasingly. “Just…you’re…god, this is…”
“Perfect.” Kiri captured his mouth with his for a long, sweet moment before pulling away again. “It’s such a perfect opportunity…”
The way his hands were moving, Bakugou did not expect the sharp, ticklish jolt that shot through his nervous system when his boyfriend started digging into his ribcage.
“…for me to tickle you!”
“GAHAHAHA – NOHOHOHOHOHOHOHO!!” Bakugou shrieked, his guard having been lowered so efficiently that he didn’t have a prayer of stopping the flood of bubbly, desperate laughter that rose up from somewhere deep within him. He shoved his arms down to fight back, but Kiri already had a good purchase, so all he could do was squirm and writhe helplessly. “YOU SOHOHOHON OF A—NAHAHAHAHAHAHAHAHA KIRIHIHIHIEHEHEHEHEHEHE!!”
“Ah-ah-ah, that’s not very nice.” Kiri giggled, reaching one hand down to squeeze at a thigh, earning a sharp squeal in response.
Bakugou tossed his head back and let out a sound that was close to a banshee’s wail when Kiri found that spot between his ribs and underarms and tickled. He started kicking frantically, laughing so hard he couldn’t think straight, only to have a weight settle on his hips and his arm pulled above his head, giving his boyfriend full access to his death spot, and he absolutely bellowed with hysterics.
“NOHOHOHOHOHO!! NOT THEHEHEHEHERE!! KIRI, PLEHEHEHEHEHEHEHEASE!!” he begged, using his free hand to push weakly at Kiri’s weight on top of him.
In response, Kirishima grabbed his other arm and shoved it above his head as well, ceasing his tickling in the process. He got his face real close to Bakugou and smirked. “If you want me to stop, then say so, Kats.”
God, that nickname. Bakugou bit his lip and looked away, refusing to speak. He wouldn’t give Kiri the satisfaction of telling him he didn’t want this to stop.
“All right, then.” Kirishima pinned his arms firmly to the bed and – to the blonde’s horror – began nibbling on that spot.
His boyfriend’s teeth and lips on his bare skin where he was unbearably ticklish was a whole other level of torture, and he made sure Kiri knew it by letting out a desperate scream, followed by laugh after shrieking, pleading laugh.
“EHEHEHEHEHEHEHEHEHEHEHE!! EIJIROU NOHOHOHOHOHOHOHOHOHO!! THAHAHAHAHAT’S TOO MUHUHUHUHUHUCH!!”
“You sure? You seem to be enjoying it~”
“I HAHAHAHAHAHAHAHATE YOU!!” Bakugou screamed, though of course he didn’t mean it. “I HAHAHAHATE YOU, I HATE YOHOHOHOHOU – GOD, PLEASE – PLEHEHEHEHEHEHEHEHEHEASE!!”
“We really should get you a gag, Kats. You’re loud.” Kirishima chuckled, then switched to his other death spot on his other side, forcing a fresh ticklish sensation to shoot through his nervous system, making Bakugou laugh so hard he thought he might lose his voice at this rate.
“EI, PLEHEHEHEHEHEHEHEASE, IT TIHIHIHIHIHIHIHICKLES!! IT TICKLES SO BAHAHAHAHAHAHAHAHAD!!”
“Aww, does it really?”
Finally, Bakugou couldn’t take another second, and he crumbled. “STAHAHAHAHAHAHAP!! PLEASE, STOP, KIHIHIHIHIHIHIHIRI!! I GIHIHIHIHIHIHIHIVE!! I GIVE!!!”
As requested, Kiri did stop, sitting up to look down at his blushing, giggling boyfriend, still keeping him pinned in place.
“W-Whahahahahat…” Bakugou gasped, wheezing out some final cackles, “Whahahat was that fohohohohor?”
Kiri beamed. “Sorry, Kats. I couldn’t help myself. You were just begging for a good tickling.”
“By being so moody about the shirts, obviously.”
“You’re the worst.”
Kirishima kissed him. “But you liked it, didn’t you?”
Bakugou blushed even harder, gritting his teeth in an embarrassed scowl. “Shut up.”
“Look, I’ll tickle you again if that’s what it takes to make you stop being such a grump.” Kiri accentuated his point by letting go of the blonde’s wrists to drag his nails down his ribs to his sides. Bakugou jumped and yelped and shot his arms down, grabbing the redhead’s wrists in his hands, giggling all over again when Kiri wiggled his fingers over his belly teasingly.
“S-Stop it…Ei, plehehease…” Bakugou felt an excited panic shoot through him when Kiri started fighting back, trying to make contact, his boyfriend’s limited strength the only thing keeping him from succeeding. “Nohohohohohoho!”
“Don’t tease me! Ei!” Bakugou gave up the battle and let Kiri scribble over his belly, trying to curl up as he giggled tiredly. “No fahahahahahair teheheheheheasing…”
“Aw, look at those dimples,” Kirishima giggled, leaning down to pepper his cheeks with kisses as he tickled softly. “You’re such a cutie when you let me tickle you.”
“Y-Yeah, yeah.” Bakugou grabbed his wrists again, pulling him away. “It’s only because I love you, idiot.”
“I know. And I’m honored, really.” The redhead finally let up, cupping the blonde’s face in his hands and kissing him deeply. “I love you, too, Katsuki. You adorable little giggle bug.”
“Don’t call me that.”
“Mmm…” Kiri nuzzled the spot just below Bakugou’s ear where it met his jaw, and the blonde absolutely melted at the touch. “I think I can convince you to let me~”
