Izuku peeled his costume off in the locker room, careful of the bruise forming between his shoulder blades. If danger sense hadn’t alerted him, he could have suffered a spinal injury. As it was, Katsuki was sure to tear him a new one when he found out.

Izuku groaned and laid his forehead against the cool metal of the locker door. All these opposite shifts were going to be the death of him.

“Alright, Midoriya?” Shouto asked from the bench behind him. Izuku couldn’t manage more than a nod…not actually feeling that well. “You should ice your back when you get home. I can help you out now if you need it.”

“That would be amazing,” the freckled hero sighed. Shouto worked fast, always quiet with his movements, and Izuku wasn’t ready when an icy hand rested between his shoulder blades. He sucked in a sharp breath and felt his lungs spasm.

“Sorry, should have warned you.”

“C-Cold,” Izuku managed to cough out. “Feels good though. I’m so sore. All I want to do is curl up with Kacchan when I get home, but he’ll be on the way out for his shift.”

His throat tightened at the need for comfort and knowing the one person he wanted close wouldn’t be around. “We haven’t even had sex in like a month!”

“I don’t think Bakugou would appreciate me knowing that,” Shouto commented.

“Don’t say anything, then,” he told his friend. Izuku groaned. “Sorry. Just pent up, I guess.”

“I read somewhere that masturbation helps with that.”

The freckled hero couldn’t help the laugh that shook his frame.

Todoroki had always been a bit behind their peers when it came to sensitive topics. Hell, the guy didn’t even know what a concert was when they were in high school. “Yes, I do that already. Most people do, but I like it better with another person, especially Kacchan.”

Shouto hummed in thought. “What about your days off?”

“We’re usually so tired that we either don’t do anything besides cuddle or it’s something quick,” Izuku sighed.

He must be more tired than he thought if he was willingly talking about his sex life with Shouto. “I just want a night where we can take our time and enjoy touching each other. I don’t know-”

“I think I understand,” Shouto said, removing his hand. The ice had numbed the blooming pain for now and Izuku was grateful. “Inasa likes to be close, too. I don’t really get sex, but I can understand that it’s important to some people.”

“Thanks,” Izuku smiled and rolled his shoulders. “I’m gonna head home.”

“See you later.”

He finished changing and walked to the train station that would bring him within a couple blocks of the apartment he shared with Kacchan.

It was a little far from the agency, but neither of them had broken the Top 100 yet and didn’t make enough to rent a place downtown.

By the time the elevator brought him to their floor, the dull radiating pain between his shoulder blades had returned. Tears clung to his lashes with each breath that nearly made his lungs spasm from the injury.

“I’m home,” Izuku called, removing his shoes in the genkan.

Kacchan came around the corner, mouth open in a wide yawn. “Hey Babe, how was patrol?”

“Got hit in a fight,” he answered, deciding it was best to rip the bandaid off. “Hurts, but it could have been a lot worse.”

“That doesn’t make me feel better,” his boyfriend deadpanned and approached in a few large strides. “Where?”

“My back.”

“Fucking hell, Izuku,” Katsuki growled. He manhandled the freckled hero until he pulled up his shirt for a good look at the injury.

“Damn right it could have been worse. As it is, you look like you lost a fight with a hammer.”

“I kind of did,” Izuku laughed nervously. “The villain could mold his hands into different tools.” Katsuki squinted his eyes angrily. “Can I have a hug?”

“You don’t have to ask, Idiot,” the blonde grumbled and pulled him in, careful of the bruise. Izuku melted into the embrace, hands sneaking under Kacchan’s shirt to caress his warm skin. Katsuki hummed contentedly, thumbs stroking the dips above Izuku’s hips.

“That feels nice.” He sighed and pressed a kiss against Kacchan’s throat.

“I gotta go,” Katsuki whispered into wild verdant curls. Izuku’s arms tightened slightly, determined to keep his favorite person close just a little bit longer.

“Wish we had more time.” Izuku swallowed tightly. “I miss you.”

“We live together, Deku.”

“Yeah, but we only see each other in passing. It sucks.” Izuku groaned. Emerald eyes glanced at the clock. They had a little bit of time. He bit his lip and glanced up at his boyfriend through thick lashes.

Katsuki went rigid for a moment. “We don’t have time.”

“Please?” Izuku whined. “I promise I’ll make it up to you.”

“When?” The blonde snapped. “All we do is quickies and blowjobs. You said it yourself, we only see each other in passing. I don’t want to keep doing this.”

Izuku felt his stomach fall out his ass. “What?”

“Not like that, Dumbass.” Katsuki groaned and stepped back, effectively cutting off any skin to skin contact. “I just mean…the sex is only okay, but I want more. I was talking with friends and I don’t know, maybe they’re right. Maybe we need to spice things up. The point is+

+something is missing and I don’t like feeling this way. Blowjobs are fine, but I don’t want- fuck! I don’t want to talk about this right now. I have to go.”

He breathed heavily through his nose and pushed past Izuku who stood rooted to the spot, stunned. “There’s curry in the fridge. Take some tylenol and ice your back. I’ll see you tonight.”

“Wait, Kacchan,” Izuku finally gasped out, eyes burning. Katsuki turned, but avoided his gaze. “Are you…are you mad at me?”

“No.” He answered quickly. “We’ll talk when I get home.”

Izuku nodded, throat too tight to respond properly. He wanted to tell Kacchan to have a good day, to wish him the best, but all that came out was a pathetic squeak. The next moment, he was alone, back throbbing and stomach hollow. The thought of eating just made him nauseous.

“What did I do?” Izuku whispered to himself. He wiped at his teary eyes and fished his phone out of his pocket. The easiest way to get to the bottom of this was to send out a group chat. He remembered to remove Kacchan at the last second.

{Deku}: Who was hanging out with Kacchan yesterday?

The response was almost immediate.

{Jirou}: Momo said he was hanging out with her and Mina at the mall.

{Mina}: Blasty came with us to the mall. What’s up?

Izuku dialed Mina’s number. She picked up on the second ring.

“Hey Mido! Everything okay?”

“I think I did something wrong, but I don’t really know what,” he groaned. “Did Kacchan say anything about me when you were hanging out?”

“Eh, it’s not really my place to say, but we went to a lingerie store. Kats was just helping us pick stuff out and we got to talking, you know. The topic of sex came up. He was pretty uncomfortable+

+talking about it, so I don’t really have anything to tell you.” Mina had been one of Kacchan’s good friends since high school, so it was surprising that he wouldn’t be more forthcoming. Unless he was and she was just being a good friend and not betraying his trust.

“He got upset when, um, when I suggested we do stuff before he had to leave for patrol,” Izuku told her nervously. Kacchan would kill him if he knew Izuku was sharing details of their intimacy with their friends.

“I knew it! He’s such a liar.” Mina switched gears, cutting off Izuku’s comment. “Mido, tell me, when was the last time you guys went all out, like date night and candles and bubble baths and really took your time in bed.”

“I don’t know,” Izuku shrugged. “It’s been a while. Ever since we switched to opposite schedules a few months ago we haven’t had much opportunity to take our time.”

“Mhmm. And you’re okay with that?”

“Well, no. I want to draw things out and cuddle and stuff too, but it’s usually just-”

“Quickies?” Mina asked.

“Yeah,” Izuku sighed. /Oh!/ “That’s why Kacchan isn’t happy? He mentioned something before he left for the agency.”

“If you’re not happy about it, why would he be?” Mina said and he could hear the roll of her eyes. “I swear, you’re as bad as Ei. Passion, Mido! You’re missing passion! Pick a night or an afternoon, hell, any time you’re both off for more than a few hours at the same time and+

+worship him. You know Kats is the type to reciprocate with action and it was probably hard for him to even tell you he was upset.”

“I can do that,” Izuku nodded and headed toward the bathroom. “Thanks, Mina.”

“Let me know if there’s any way I can help.”

“Will do! Talk to you later.” He hung up and stripped so he could shower. Pulling back the folding door to the washer and dryer, he popped open the washer door. “Oh, Kacchan forgot to switch the laundry.”

Izuku grabbed an armful of damp clothes and tossed them in the dryer. A couple of garments didn’t make it, falling to the floor at his feet. He bent to pick them up and stopped short.

“What is…” he gasped at the Deku branded thong laying across the top of his foot. “Kacchan,” he breathed, imagining his boyfriend wearing his colors. Heat pooled between his legs, cock nearly standing at attention already.

Izuku tossed the thong into the dryer with the rest of the clothes and started the cycle. He couldn’t stop thinking about why Kacchan would hide something like that from him. Then he remembered that Mina said he went to a lingerie store with her. Were they new?

He bit his lip and groaned and the pulsing between his legs, reaching down to lightly stroke his length while he started the shower.

The warm water massaged his skin deliciously, the wetness aiding his hand up and down his hard cock. He wished Kacchan was here now so he could ravage him, show him how much he loves him and appreciates him. To think his boyfriend was upset because of their strained sex life.

Did Kacchan think he didn’t want to put any effort in? Because that was so far from the truth. All Izuku wanted to do was be buried in his tight heat, covering every inch of the blonde in kisses and marks so everyone knew who he belonged to.

Izuku's hand stroked faster, tightening his grip and twisting around the head. His knees shook with pleasure and he placed a hand on the shower wall to steady himself.

“Kacchan,” he moaned. Did his boyfriend buy more than just the one thong? Was he hiding more sexy clothes that Izuku could admire on the pretty blonde? He whined feeling his orgasm approaching fast, mind supplying raunchy image after raunchy image - Kacchan red faced and begging+

+thong pulled aside while Izuku pounded his ass. Izuku’s colors gripping Kacchan’s skin, Izuku’s marks painted across his neck and chest and thighs. He gasped and shuddered as he tipped over the edge, his cum washing away by the drain with the shower spray.

Once the pleasure faded, his bruise throbbed painfully. “Ow,” Izuku groaned, washing off quickly and stiffly drying himself off. He changed and grabbed meds from the cabinet before shuffling to the kitchen to reheat the curry Kacchan told him about.

While he ate, Izuku looked over their schedules. There weren’t many days where they had more than a couple hours of overlap. It made him feel even more disappointed than he had when Kacchan left the apartment. The freckled hero groaned.

If he wasn’t so damn sore, they could take their time tonight. Katsuki wasn’t scheduled until mid-day and he wasn’t needed at the agency until later for an overnight.

With a belly full of his boyfriend’s delicious cooking, Izuku knew sleep was next on his list.

It was difficult to find a comfortable position with how sore his back was, but after another round of tylenol and an icepack held between his shoulders by an extra pillow, he was dead to the world.

-
-
The world was fuzzy, warm, and oddly, smelled like burnt sugar. Izuku hummed at the deft fingers weaving through his hair, teasing the skin behind his ear.

His eyes fluttered open and he registered that he was still in bed, situated on his stomach to relieve pressure on his back. His head was turned to the side, facing a freshly showered Kacchan.

“Mmm, ‘time is it?” Izuku grumbled.

“Almost 6,” Katsuki told him softly, his fingers never halting their ministrations. “How’s your back?”

“Sore,” he responded, rolling his shoulders. Some of the ache from this morning had dissipated. “But better.”

A deep breath filled his lungs and he rolled to stretch. “Kacchan, I’m sorry that I upset you this morning.”

The blonde’s face twisted with a few emotions, before settling into his signature scowl.

Katsuki shrugged, “I wasn’t mad at you. Just sucks that our schedules have been shit for months. Feels like I never see you. Shouldn’t have taken it out on you.”

“You know I would ravish you if we had time, right?” Izuku asked, pulling himself into a sitting position. “I like making you squirm."

A smirk pulled at his lips before he became serious again. “I just thought something was better than nothing. If you don’t like quickies between shifts, you should have said something.”

Katsuki sighed and laid his head in Izuku’s lap. Freckled fingers took the opportunity to run through blonde locks. “Didn’t say I don’t like them. Just wish it wasn’t /only/ quickies and blowjobs.”

Izuku thought back on his conversation with Mina earlier today. She’d mentioned a lack of passion was likely the cause of Kacchan’s negative response and he had to admit, there really wasn’t any when all they did was furiously jack each other off or bend the other over+

+for a few quick thrusts before it was over. Not much kissing was going on during their romps, or touching, or soft words of encouragement. All business, no play. Then, Izuku remembered the thong he’d found in the washer and felt his cheeks grow hot.

His hand stopped moving through Kacchan’s hair and his boyfriend shifted to find out what caused the disturbance.

“What?” Katsuki asked suspiciously.

“Umm…I threw my laundry in the washer after you left for patrol.”

Scarlet eyes rolled in their sockets, “Good for you.”

“No, Kacchan,” Izuku chewed on his bottom lip and his boyfriend’s gaze narrowed. “You h-had laundry in the washer, so I switched the load. And-”

Katsuki sat up quickly, eyes wild and ears turning a furious pink. “Shit. I-”

“D-Did you buy that yesterday when you went out with the girls?” He asked. “You said something about spicing things up, was that why you bought it? I’m flattered, really. You know I like when you wear my colors.”

“I guess,” Katsuki shrugged, the blush on his ears spreading to his cheekbones. “They feel nice.”

Izuku chewed harder on his bottom lip, feeling his cock start to fill out. “Yeah, baby? Wanna show me how nice they feel?”

His boyfriend nodded, “But you have to promise me that we’ll take our time.”

“I promise,” Izuku smiled and leaned forward to capture Katsuki’s lips. The blonde melted into him, tension bleeding out of his shoulders.

They sat like that for a few minutes, lips moving and tongues tasting lazily.

When they broke apart, Kacchan’s lips were swollen and shiny with spit, eyes glazed over with lust. “Be right back,” he said, sliding off the bed.

While he was gone, Izuku took the chance to strip down to his boxers, the material tenting over his straining cock. His fingers stroked lightly along the underside, a pleasant heat radiating over his skin.

And then Kacchan appeared in nothing but that Deku themed thong, cock half hard and bulging in the fabric.

“Oh,” Izuku breathed, dick twitching hard and bouncing off the tips of his fingers. “C’mere.”

Katsuki slinked onto the bed, shoulders moving like a predatory cat as he moved to straddle Izuku’s thighs. Freckled fingers traced the edges of the waistband, causing a shiver to run through his boyfriend’s body.

He dug a digit under the elastic and pulled back just enough that when he let go it snapped satisfyingly against Kacchan’s hip. The blonde moaned low, pupils dilating so there was almost no scarlet left.

“So pretty,” Izuku hummed. “Look at you, all wrapped up in my colors.” He dragged a finger over the straining bulge in the thong. Kacchan panted and squirmed in response, silently begging for a firmer touch.

He gripped his boyfriend’s thighs, covered in soft blonde peach fuzz, and squeezed until little red marks appeared under his fingertips. Izuku hummed again, sliding his hands up and over Kacchan’s hips to dig his fingers into the meat of his ass.

“Yesss,” Katsuki gasped, arching into the touch. “Kiss me.”

Izuku took no time in complying, tilting his head back to meet Kacchan in an open-mouthed kiss. It turned heated within seconds, tongues tangling and moans vibrating in their throats.

Katsuki pulled away for air, drool dribbling over his chin before he rolled his hips, rutting their cocks together. Electricity shot across every nerve in Izuku’s body and he arched his back into the sensation.

“Kacchan,” he panted, pulling the blonde closer. Lips latched onto pale shoulders, sucking little red marks and leaving the occasional bite. Katsuki continued to squirm in his lap, their cocks rubbing together every so often and leaving them both a shivering mess.

Izuku moved to roll them over, but aborted with a sharp hiss as his back protested.

“Shit, Izuku, don’t hurt yourself,” Katsuki fussed over him.

“I want to fuck you so bad in this little thing,” Izuku pouted, snapping the string of the thong again.

“You will.” Emerald eyes tracked up gorgeous pecs with pert nipples, across the little marks he’d placed across his boyfriend’s shoulders. “But let me do the work.”

Katsuki leaned down to recapture his lips in a heated kiss, hands sliding over his heated skin and tickling his sensitive stomach before hooking into his boxers and pulling them down.

Izuku sighed at the feeling of his cock being released, which quickly turned into a hiss of pleasure when warm, calloused fingers wrapped around him and stroked. “Mmm, feels so good. Wanna make Kacchan feel good, too.”

A bottle of lube slapped against his stomach. Izuku hadn’t even realized Katsuki had grabbed it already. “Better get going then,” Kacchan told him, leaning back to pull the g-string away, revealing his pink puckered hole.

With finger wet, Izuku circled Katsuki’s rim, teasing with pressure and enjoying the way his boyfriend’s cock twitched. When his first digit slid in easily, he moaned low with excitement.

Izuku wiggled his finger around a bit to coat those tight, velvety walls before adding a second and scissoring him open.

Before long Kacchan was fucking himself on four fingers, head tossed back and hands gripping Izuku’s thighs. Moan after moan panted out from between his lips, movements frantic when the angle was just right.

“Fuck, I want your cock,” Katsuki breathed before wrapping his hand around Izuku’s wrist to pull him away. “Hope you’re ready, Deku.”

“Always ready for Kacchan,” Izuku grinned and placed his hands on his boyfriend’s hips to help steady him. His thumbs teased over the teal strings of the thong.

When Katsuki lowered himself, Izuku realized the skimpy garment allowed him an unobstructed view of his cock disappearing into that deliciously tight heat. He let his head fall back against the headboard, knowing full well he’d blow his load if he kept watching.

The first time Katsuki raised himself only to fall back into Izuku’s lap, the greenette was sure he was done for. The sounds, the feel, the smell - he was surrounded by Kacchan in every way that mattered. Fuck, he’d missed this so much.

“God fucking,” Katsuki panted as he set a brutual pace. “You’re rock hard. Feels so good stretching me open.” Izuku gave an experimental roll of his hips, not trusting himself to answer.

“Ah ah, right there,” Katsuki panted, leaning farther back than before to grip onto Izuku’s calves and ride him into oblivion.

The mattress springs creaked under their vigorous movement, headboard banging against the wall with every thrust.

Kacchan refused to stay quiet, all manner of swears, moans and pants filling the room to accompany the sound of skin slapping on skin. Izuku palmed at Katsuki’s contained cock, the fabric of the thong soft against his palm and wet from the blonde’s arousal.

“Like that,” Katsuki panted, “Again. Do that again.” Izuku complied, hand rubbing circles over the head of Kacchan’s cock.

The blonde whimpered cutely and Izuku knew he was done for. Watching his cock disappear and reappear from that perfect hole, his hero colors wrapped around his boyfriend’s cock - it was all too much.

He was hurtling toward the point of no return, his own moans reaching a fever pitch just as the vice around his cock became tighter.

“Ah, c-cumming,” Izuku cried, thrusting erratically. Kacchan let out a pleasured shriek, hole fluttering around Deku's twitching cock.

They came together, jolting through overwhelming pleasure. Katsuki walking himself back into a sitting position until his hands shakily rested on Izuku’s chest. He leaned forward and planted a sloppy, open mouthed kiss against swollen lips, all teeth and tongue and passion.

“Fucking hell,” Katsuki panted, forehead thumped against Izuku’s collarbone. “I’ve missed this so goddamn much.”

Izuku helped them roll over, his back protesting and body shivering as his cock slipped out of Katsuki’s ass. “I’ve missed you so goddamn much.”

He peppered kissed over the blonde’s face, fingers ghosting over the old scars littering his shoulders. “I promise we’ll do things like this more often. I don’t ever want you to think something is missing from our relationship. I love you, Kacchan. More than anything.”

Lips tickled at Izuku’s collarbone as his boyfriend planted butterfly kisses across his skin. “Love you too, Nerd.” They laid like that for a while, basking in the afterglow under their hearts stopped thundering in their chests.

Izuku traced the bumps of Katsuki’s vertebrae with his knuckles, lazily enjoying the skin to skin contact. His mind wandered to the soiled thong and was about to ask Kacchan if he wanted to change when a thought struck him.

He swallowed thickly, cock twitching with interest. “Hey, Kacchan?”

“Hmm?” His boyfriend hummed in question.

“What else did you buy at the store yesterday?”

Blonde spikes tickled under his chin as Katsuki shifted to look him in the eyes. A smirk pulled at his lips. “I’ll show you,” he chuckled, rising from the bed to retrieve the lingerie store bag.

A strappy looking body harness and a set of Deku themed stockings were tossed onto the bed. Oh, there was no denying the new erection growing between his legs. He reached out to touch the stockings, rubbing the material between his thumb and forefinger.

They were soft and silky, pleasant to the touch. Izuku smiled and tossed them back to Katsuki. “Put them on. The harness, too,” he ordered, voice laced with hunger. He would make sure they got good use out of Kacchan’s new wardrobe.
