Exposed With Monsters

Chapter Text

“For the last time, yes, I’m sick. Yes, I’m taking the entire week off, and no you can not come over and play mother hen,” Katsuki said, forcing his voice to sound as nasal as he could over the phone. He continued spraying the Odor Neutralizer around the house and over himself to cover up the Pre-Heat Pheromones that continued to linger. He couldn’t afford to let a single Scent remain to be caught later. “And just to make sure none of you bother me, I won’t even be at home. I’m going to a hotel.”

“Can you at least tell me where you’ll be in case you need something?” Kirishima asked. Bakugou shoved the can of odor neutralizer in his overnight bag and mentally thanked the Doc for providing it. He’d woken up smelling like a rose bush and cursed his own, stupid body when the heady smell of Pre-Heat pheromones joined his natural Scent the next day. Kirishima asked, “What if there’s an emergency?”

“Then I’ll deal with it,” Katsuki said. He looked over his apartment for anything that might be out of place or give him away. He grabbed his empty bottle of suppressants and shoved it in his overnight bag. “I have the flu, not a deadly disease. I was fine yesterday when I stayed home, I’ll be fine the rest of the week.”

“But the fact you’re taking the week off means it got worse!” Kirishima said. Which was the truth. Katsuki had taken the first day off to deal with the fact he had a Scent again and mentally map out his choices. And then the second day he started producing Pre-Heat pheromones and realized his body really hated him. Kirishima said again, “I promise I won’t tell Midoriya if that’s what you’re worried about.”

“I appreciate it,” Katsuki said, giving him that much of a thought. “But I just want to sleep this off without anyone hovering or bothering me. I’ll be in a hotel with maids and shit if something really bad happens.”

Kirishima audibly huffed on the other end. “But—”

“But nothing!” Katsuki said, cutting him off. “If I don’t do this, none of you will leave me alone. And besides, Deku’d weasel the information out of you and you know it.”

“Point,” Kirishima said. “But are you sure?”

No, he wasn’t sure at all.

He’d called Dabi in a minor panic after the new pheromones started to flood his apartment and agreed to fuck a League of Villains member through the inevitable Heat that’d be there whether Katsuki wanted it or not. He didn’t even know which one Dabi was going to bring because it was so short notice and they were “busy” or some bullshit, which meant Dabi had to see who was even available.

Katsuki tried not to think too hard about it.

He exhaled slowly, gathering himself so he could hide the nerves under his voice. Katsuki said, “I’m sure and if I’m really not better in a week, I’ll call you.”

“Are you at least going to answer your phone?” Kirishima asked, weakly.

“The phone has built in GPS so it’s staying in my apartment,” Katsuki said. He finished packing the last of his things into the bag and grabbed a dark hoodie. “So this is it.”

“I really don’t like this, Bakugou,” Kirishima said, something edging into his voice that Katsuki hadn’t heard before. The disapproval and frustration were odd to hear from the Alpha. Kirishima grunted and barely relented. “Are you sure you’re okay?”

“I’ll see you in a week,” Katsuki said.

“You better call me when you get back home,” Kirishima said. “Or I’m going to break down some hotel doors looking for you.”

“I will call,” Katsuki said.

Or he would call if he lived through this, anyway.

“You better,” Kirishima said, cementing that he meant what he had said.

“Bye,” Katsuki said.

He clicked the phone off and pressed his forehead against the screen. Katsuki went into his bedroom and threw the phone on the mattress, ignoring the mountain of texts he’d received from his other friends and Deku. Katsuki went back into the main section of his apartment and double checked all of the appliances were unplugged and his stove was off. He did one last sweep before grabbing his bag and his keys and locking the door behind him.

Katsuki opened the stairwell and snuck out the back of his building, heart pounding in his chest. He was doing this. He was fucking doing this and it was the stupidest thing he’d ever done in his life.

But the alternative was worse.

No one he cared about could know he was an Omega.

Not Kirishima.

Not Deku.

No one.

If sleeping with the devil was what it took to keep his Class a secret, he’d live with it.

Dabi had told Bakugou that he had options, but when it came down to it, there was only one choice for the skittish, ignorant Omega.

He shivered in anticipation as he knocked on the bedroom door. Dabi had made all the arrangements needed for a perfect Heat week save for this one last part. The most important part: The Alpha. Dabi was one request away from solving all of dear Ground Zero’s problems.

He couldn’t picture the Alpha refusing—not when Katsuki Bakugou was on the line.

This was a chance of a lifetime and they’d be idiots not to take advantage.

Katsuki dropped his bag on the edge of the bed nearest to the window in the small hotel room. The place was nicer than he thought for something Dabi got on short notice and much cleaner than he’d expected after seeing the rundown exterior with chipped paint and rusted window bars. Katsuki frowned at the size of the room though. There wasn’t much aside from the two separate beds and a small attached bath and shower, with maybe a foot or two of space between the beds and the walls.

He supposed it was room enough for what they’d be doing.

The key to the room had been where Dabi said it would be—in a dumpster two blocks away—and the name was registered under a false identity. The Fire Quirk user had told Katsuki there was a back door under a broken light so if Katsuki timed it right, no one would see him enter the hotel, let alone the room.

Dabi said in a text that he’d be there tomorrow before things got “heated up” and that he was still working on the specifics.

That was fine with Katsuki. He still hadn’t stopped releasing Pre-Heat pheromones and the odor neutralizer was slowly losing its effectiveness. Katsuki wasn’t exactly in the mood to watch whatever Alpha inevitably showed up lose their mind because of something as stupid as his Scent, so Dabi could be as late as he wanted.

The other Omega assured him that the pheromones would stop by the next morning, and his Heat should—the key word being ‘should’—start late in the evening.

Katsuki had to trust that was true.

He pulled off his hoodie, throwing it on his bag. Katsuki groaned, running his hands through his hair and dropped onto the bed. The mattress bounced under him, too soft and plush. Katsuki sprawled out, staring at the ceiling.

He was doing this.

Katsuki was going to sleep with an Alpha.

He was going to have another Heat.

His gut twisted as bad memories knocked at the back of his head. Katsuki curled in on himself as he rolled over, tugging the covers with him. He closed his eyes and felt the phantom pain of the ache in his hips and whined. Katsuki started counting, willing himself to go to sleep so he could get the next day done and over with.

“Okay, so he’s probably going to be on edge because this is his first Heat with an Alpha and no one fucked the nerves out of him yesterday during his Pre-Heat,” Dabi said, stepping outside of the Warp Gate Kurogiri provided. His Alpha followed behind, hands stuffed in his hoodie pockets. “When you add in the fact he doesn’t know which Alpha is coming, he might be difficult at first.”

“When is Katsuki Bakugou not difficult?” Shigaraki asked, stepping out of the Warp Gate behind Dabi. He waved Kurogiri away once he was clear and checked his phone for messages. He tapped a few replies while staring at the screen. “Why’d he agree to this again?”

“Desperation,” Dabi said. He dug through his pockets for the second key to the hotel room and tugged out the card. “But hey, even if he gets angry it’s you, all we need to do is wait a few hours. He’ll be begging for your dick as the only Alpha in the room, so it’s not going to matter what he wants.”

“You never did tell me why you care so much,” Shigaraki asked, leaning forward. His breath felt hot on the small exposed portion of living skin on his cheek. “You’re not the type.”

“He asked,” Dabi said, low and true. He clutched at the keycard, leaning back to touch his shoulder to Shigaraki’s side. “Most people don’t bother to ask me for anything, so why not help him out?”

He put his hand on the door, breathing out. Shigaraki wasn’t wrong—Dabi usually didn’t bother. He didn’t stick his neck out for others, Omega or not, and he minded his own business. Dabi turned a blind eye to more than one injustice in the world. But he’d never met an Omega that actually went through a Heat alone and managed to get back up with fight still left in him.

Seeing Bakugou at that small bar full of Villains and rowdy Alpha, it was pretty clear Bakugou wouldn’t be able to do that a second time.

Even a guy like Dabi could still feel compassion if pushed hard enough. Shigaraki had been right long ago: Bakugou felt like he belonged with them in the underground more than under the spotlight with the Heroes.

Bakugou had sure spent enough of his life hiding in plain sight as it is. It might do him some good to be himself, open and exposed.

“Besides, you’re going to be in a good mood for weeks after this,” Dabi said, lightening his voice. It wouldn’t be too good for Shigaraki to know how invested he really was in his fellow Omega. Dabi looked over his shoulder and raised his brows with a teasing smirk. “Win-win for me.”

Shigaraki snorted but his mouth twitched in an amused smile—score.

Dabi knocked twice on the door as a warning and pushed in the keycard. The door unlocked and Dabi let himself and Shigaraki in.

“Bakugou?” Dabi asked, dropping his duffle bag on the bed nearest the door. He saw a second bag there, but didn’t see it’s owner—but he could the shower running. Dabi walked over to the door and knocked on it twice. “Yo, Bakugou. Are you in there?”

No one answered.

Dabi knocked harder. “Hey! Did you fall asleep?”

Still no answer.

Dabi tried the knob, surprised to find it wasn’t locked and pushed it open. He took a step in and met a sopping, soaked towel thick with liquid. “Well, shit.”

Bakugou sat in the bottom of the shower, the curtain pulled all the way back to the wall. The shower ran on full blast, pouring over the arms that covered his head as he sat in the corner and hid his face in his knees.

The water splashed onto the floor and Dabi reached over to shut off the shower. He whispered, “Bakugou?”

The other Omega flinched hard at the address. Bakugou released a full body shiver and curled in tighter onto himself. He muttered under his breath over and over: “I can’t do it. I can’t do it. I can’t do it…”

Shigaraki yanked Dabi out of the bathroom by the back of his shirt and twisted him around. He grabbed Dabi’s chin with one hand, fingers digging in tight to the skin of his cheek. He pointed at Bakugou in the tub with his other arm and the displeasure in his voice sent a shiver down Dabi’s spine. “He’s not on edge, he’s panicked!”

“I will handle it,” Dabi said, holding up both arms in a defensive position. “Give me five minutes.”

Shigaraki let go of Dabi's face and blew his hair out of his eyes, turning to walk back to the bed. He sat next to the duffles and pulled one knee up on the mattress.

He didn’t pull out his game console.

Dabi swallowed and helped himself back into the bathroom.

Katsuki smelled sandalwood in the hotel room, strong and harsh. Sandalwood. He’d never forget that Scent as long as he lived: Shigaraki of the League of Villains.

Dabi brought Shigaraki—the most wanted man on the planet was ten feet away on the other side of the wall and Katsuki couldn’t do shit because he had a panic attack on the floor.

If he’d known taking a shower would remind him of his two weeks trapped in a bathroom on the floor and in the tub and send him spiraling into a flashback, he would have stayed dirty and let them live with it.

“Shit,” Katsuki said, digging his hands into the back of his hair. He shivered in the cold air, his constant stream of hot water gone. Dabi and Shigaraki’s arrival knocked him out of the initial attack, but he didn’t want to move. This wasn’t happening. He wasn’t uncomfortably aroused on the floor of a shower and he wasn’t going to have a Heat.

Dabi dragged him out of his denial along with the shower base.

“I’d like to play nice, but neither of us have time for it,” Dabi said, shoving a towel over Katsuki’s head and pulling him up by the arms. He whispered, “Does it hurt? Did you start early? Talk to me or I can’t fix it.”

“Nothing started early,” Katsuki said, breathing heavy and hating the tremors that continued to wrack his hands. He grabbed the back of his palm and squeezed. No sense in hiding it after he’d been caught naked in the shower by a Villain. “I had a flashback and handled it badly.”

“Trauma’ll do that,” Dabi said. He rubbed Katsuki’s arm and patted it through the towel but he could tell his attention was half on the Alpha in the other room. Funny enough, his anxious state helped calm Katsuki down. Dabi licked the side of his teeth. “You seem better now. Are you good?”

“Good as I’m going to get,” Katsuki said, still shivering. He clutched the towel closer and lowered his voice. “But really? Shigaraki? I thought you were going to bring Twice or some shit.”

Even Toga would have been better than that—that monster.

Dabi slapped a hand on Katsuki’s shoulder and leaned in, until they were a breath away. “Trust me. Shigaraki’s the best of the lot. Don’t sell yourself short, Kacchan.”

“Call me that again and I’m going to introduce your face to my Quirk and the Doc’ll have more than infected stitches to fix,” Katsuki said, growling under his breath. “You got that?”

“Are you sure you’re not taking Alpha supplements?” Dabi asked.

Katsuki shoved his hand off. “If I was, I’d have already blown your head off.”

Dabi laughed and Katsuki tugged the towel off his head. While the other snickered, he stared at himself in the mirror and it hit him he was very naked—

“Is this still happening or what?”

Katsuki jumped at the sudden new voice and took a step away from the bathroom doorway, his heart leaping in his chest. Shigaraki stood there, scratching his neck and dressed down in a black hoodie and jeans. His exposed face hid none of his wrinkles or chapped lips and his steady gaze locked on Katsuki’s face. He lowered the towel near his waist for modesty—he could keep it for now, dammit—and pretended he hadn’t been so preoccupied that he hadn’t noticed the Leader of the League of Villains sneak up on him.

“As far as I know it is,” Dabi said, stepping between Katsuki and Shigaraki. “Because otherwise I’ve done nothing but waste Shigaraki’s time and on top of that, I’ll need to find another Alpha in an hour that’ll I’ll have to kill afterwards since that whole thing about you being an Omega is a big secret.”

Katsuki glared at Dabi, but eventually looked at Shigaraki. Drowning in his dark clothes and without his costume or mask, he looked like a normal person who didn’t get enough sleep, but his Scent stayed strong and reminded Katsuki of restraints and an old bar. He sucked in a shaky breath.

He didn’t really have a choice.

“The plan’s the same,” Katsuki said.

Shigaraki snorted and left the bathroom, heading back to sit on the bed. He crossed one leg over the other and rested his chin on his hand.

Katsuki sat across from him on the other bed, towel over his lap with no idea what happened now. Small talk was the last thing on his mind and Katsuki didn’t want to think about what came next.

He felt cold and raw, his heart pounding as time ticked down.

Bakugou and Shigaraki had fallen into an awkward stare down: Bakugou still rigid as a steel rod and Shigaraki too thoughtful for it to mean anything good. It looked like Dabi had some damage control to do. This is why he didn’t do nice things. It was way too much work.

So he might as well get something out of it, too.

“You’re so tense it hurts to look at you,” Dabi said, flicking Bakugou in the side of the head. The Pro Hero stopped looking lost and narrowed his eyes, glaring over his shoulder and Dabi took that as a partial win. “We should fix that in the couple hours we have to kill.”

“What are you doing?” Bakugou asked, eyes widening as Dabi pulled his shirt over his head.

“You look like you’re feeling shy being the only naked guy in the room, so I’m giving you some company,” Dabi said.

“You do not need to do that,” Bakugou said, cheeks turning redder. He clutched at the stupid towel and glanced at Shigaraki, who’s expression hadn’t changed aside from a slight uptick in curiosity. “Put your pants back on!”

“You’re going to be naked and exposed for four days straight in a couple hours and you still want to protect your virtue with a towel,” Dabi said, dropping his boxers. He bit back the laugh when Bakugou immediately looked away. He threw them on top of his stack of clothes and sat next to Bakugou on the bed, throwing an arm around his shoulder. A shiver worked through the other’s entire body and not the good kind—solid nerves hid under those muscles. “You need to relax.”

“I’m in a room with two murderers, how am I supposed to relax?” Bakugou growled back.

“You keep bringing that up, but none of that matters!” Dabi said, leaning in and following when Bakugou attempted to keep the distance. “The more you focus on that, the worse it’s going to be. From this point on, there’s no Pro Heroes or Villains to be found—just a trio of people about to have some fun.”

“Trio?” Bakugou asked.

“You bet,” Dabi said. He leaned on Bakugou’s side and reached up to twist Bakugou's head to look back at Shigaraki. “You see that? That is one bored Alpha and I have the perfect idea to make sure we’re all happy.”

Bakugou looked as confused as ever. “And how are you going to do that?”

“I’m going to kill two birds with one stone,” Dabi said. He touched the side of Bakugou’s face and used that split-second of frozen fear to help himself to Bakugou’s lap. He kissed the other Omega hard, grinning into the squeak. “Play with me. It’ll entertain him and loosen you up for the main event later, yeah?”

“What?” Bakugou said, jerking back. He dropped on his elbows, eyes wide and breath heavy.

“You’re a nervous virgin, Shigaraki’s bored, and I want to get laid,” Dabi said. He dropped forward, throwing his arms around Bakugou’s shoulders as he pressed their chests together. “We’ve got the time to kill, so fuck me.”

Bakugou had looked less terrified when Dabi and the League had kidnapped him as a teenager. Dabi didn’t know if that was adorable or just sad. He sat up and manhandled Bakugou with him until Dabi’s back was on the mattress and Shigaraki had a good view of Bakugou sitting between his knees. The other Omega froze, eyes wide and chest pounding from his heavy breath and racing heart.

“Stop thinking so hard,” Dabi said. He grabbed the towel that sat between them and threw it across the bed. Dabi scooted back so that his nether regions were more visible to the timid Omega between his legs. Bakugou stared for a moment before he averted his gaze. Dabi sat up on the pillow and knocked Bakugou’s side with his knee. “You ever masturbated?”

Katsuki wanted to die. He stared at Dabi’s teasing smirk, stretched wide and contrasting with the half-lidded eyes. Katsuki wasn’t sure his heart could take this. “Are you trying to ask the most inappropriate things possible?”

“You’re here to have wild sex for a week,” Dabi said, dropping his hand between his legs. Katsuki absolutely did not look down. “I’m pretty sure we’re past being shy about that sort of thing, don’t you?”

He had a point.

But he didn’t have to be so—so open about it all!

“So is that a no?” Dabi asked, his upper arm moving. He licked his lip, staring at Katsuki’s face and read him like a book. “That’s a no. Then don’t think of this as sex, think of it as an educational opportunity. It’s easier to look at someone else than yourself, anyway.”

Dabi put Katsuki’s hand on his inner thigh and widened his legs further. “Do whatever the hell you want: Touch me or make me sit here hot and bothered until I give up and put on a show for both of you—I don’t really care. With that Alpha envy you’ve got going on, I’m sure this is right up your alley.”

Katsuki had no idea how his life had gotten to this point. Dabi’s skin felt warm under his palm and he was already wet—they both were. At some point, Katsuki’s own arousal had come to life and he wasn’t sure if it was the Heat starting up or being around the smell of sex and naked bodies.

“You’re not going to hurt me,” Dabi said, voice quieter. He flicked leaned back on one elbow and kept his other hand to himself, giving Katsuki all the freedom. “I’ll be impressed if you manage to make me come, though, so consider it a personal challenge.”

Katsuki squeezed Dabi’s thigh and stared at his belly and the abs hidden behind his shabby clothes. They stayed like that while Katsuki collected himself. Dabi didn’t move, didn’t urge him on past that last bit of teasing.

It was his choice.

Dabi felt Bakugou’s shaking hand trail down his thigh until it touched the joint between his thigh and hip. He looked over Katsuki’s shoulder at Shigaraki, who at covered his lower mouth with his hand, fingers spread over his nose and cheek. The Alpha’s eyes were locked on Bakugou’s face. Dabi wasn’t sure if that was good or bad, but he was in too deep now to change plans.

“This is so stupid,” Bakugou said under his breath.

He followed the blunt statement by touching Dabi for the first time, using his thumb to spread him open. Bakugou’s trembling fingers dipped inside and Dabi watched his eyes focus as he looked down to see what he was doing.

The timid touch gained more confidence as Dabi’s breath picked up and he encouraged Bakugou with verbal cues—appropriate moans and groans, though more exaggerated than necessary.

The guy needed a confidence boost and Dabi could tell him how to actually give a hand job later.

Bakugou found a steady rhythm with his exploration, gaining the confidence to push his fingers in farther. He looked up every so often to watch Dabi’s face and he greeted those red eyes with a smile and a shift of his hip. Dabi said, “Keep going.”

“Okay,” Bakugou said. He shifted in his seat and Dabi grinned at the damp spot under him on the sheet. Bakugou’s own breath picked up and this had been a good idea. If Bakugou got any more aroused, he’d be more than happy to let someone help him out. Bakugou licked his lip. “Does that feel good at all?”

“It doesn’t feel bad,” Dabi said, deciding not to lie. “But you’re not exactly on your way to getting an orgasm out of me, either. You don’t need to be so gentle.”

Bakugou pouted and Dabi wanted to pinch his cheeks.

“This’ll help,” Shigaraki said, holding out a dildo Dabi had shoved into his duffle bag.

He laughed when Bakugou jumped for the second time that night.

How did Katsuki keep forgetting Shigaraki was there? The quiet asshole’s lip twitched as he smiled, still holding the stupid purple dildo with one finger raised.

“He’s more than worked up enough for it,” Shigaraki said, waving the toy toward Dabi. He reached over and shoved it in Katsuki’s hand, patting his arm after he let it go. “He’s going to complain all night if you don’t get him off and you look like you can use all the help you can get.”

Katsuki hated that man.

Dabi snickered into the pillow, dragging it over to shove his face in it as he laughed. He looked over the top and spread his legs further. “He’s not wrong. You stretched me more than enough for that just messing around.”

He stared at the dildo and looked back down at Dabi, breath still rough and thighs shaking from his arousal.

Katsuki was in this deep already, he might as well go all the way—what did he have to lose?

Under the watchful eye of Shigaraki, he worked the damn thing inside of Dabi as far as it would go, taking his first real bit of satisfaction from the night when Dabi groaned and demanded he do it again harder.

It’d taken some handholding and assistance from his Alpha, but Dabi came from Bakugou’s attention. He shuddered through the end of his orgasm and reached down to pull the toy out.

“Good job,” Dabi said, sitting up and grabbing Bakugou’s towel from earlier to wipe away the excess between his legs. “With some practice, you’ll be pretty good at that.”

“Whatever,” Bakugou said, averting his gaze. He shifted his hips on the bed, hands grabbing the mattress between his thighs. “Happy to help.”

Dabi leaned on him and kissed his shoulder. “There was only one part we missed out on, but thankfully, we’ve still got some time to do this right.”

“And what’s that?” Bakugou asked.

“You didn’t kiss me,” Dabi said. He grabbed Bakugou’s face and kissed him again. He nipped until Bakugou opened his mouth and let Dabi inside to deepen it. He bit Bakugou’s lip and kissed him again. “Make out with me. We’ve still got time to kill and an Alpha to keep entertained.”

“You just want to make out,” Bakugou said, narrowing his eyes.

“He can learn,” Shigaraki said. He sprawled out on the bed, still watching the other two. “Impressive.”

“Shut up,” Bakugou said, throwing a pillow across the room. Shigaraki grabbed it, disintegrating the pillow with a smirk and Bakugou took it as personal challenge and went for the dildo next. “Stop showing off!”

Dabi grinned to himself, watching as Bakugou and Shigaraki bickered. The other Omega looked unamused and embarrassed as he shouted back responses to Shigaraki’s teasing and biting remarks—but he wasn’t scared.

Mission accomplished.

And none too soon, either. He tugged Bakugou over by the thigh and kissed him again to distract him from the smirking Alpha. In a few minutes, he’d be hot and bothered from something else entirely and Dabi wanted to get what he could out of the poor guy before he handed him over to Shigaraki.

Dabi fell back, pulling Bakugou with him until the other was spread out on top of him. He continued the kiss, slow and gentle, knowing full well they were doing this backwards—but hey, he wouldn’t mind a round two if it came to that.

Katsuki wasn’t sure how he’d been conned into making out with Dabi while Shigaraki made rude comments, but it had happened.

The worst part of it all was that it felt good, especially when Dabi rubbed his side, scratching the metal of his stitches into Katsuki’s skin. He peppered teasing words between the kissing and kept their bodies touching, getting himself worked up all over again.

But Dabi wasn’t the only one hot and bothered. After about ten minutes of lazy kissing and touching, Katsuki felt too warm. His skin crawled and no amount of kissing Dabi gave any sense of relief.

He shifted his hips and groaned, shoving his face into Dabi’s shoulder. Katsuki clutched at the bed, breath hard and his brain yelled that he needed something more substantial.

Katsuki felt empty and his loins burned for attention.

“I guess it’s time for me to tag out,” Dabi whispered. He ruffled Katsuki’s hair and slipped out from under him. Katsuki whimpered at the cold air that met him, already missing the other warm body. Dabi cracked his spine and said, “He’s all yours.”

“I’ll be sure to take good care of him,” Shigaraki said, pressing his hand into Katsuki’s back. He trailed it down his spine, four fingers digging in and massaging the muscle. Shigaraki sat next to Katsuki on the bed and rubbed his thumb in a circle on Katsuki’s back. He inhaled the Scent of sandalwood and relaxed under the touch. Shigaraki murmured, “Look at you. Do you want me to help you out?”

“Please,” Katsuki said, ashamed of the whine in his own voice. He felt the desire in his belly grow, the lust still fresh and needy. But Katsuki remembered. He knew what came next. “Before it hurts.”

Shigaraki’s hand stilled on his back and he curled forward, the fabric of his clothes scratching along Katsuki’s skin. He kissed Katsuki at the joint between his shoulder and neck, breath hot. “Of course.”

Katsuki had no words for the relief he felt when Shigaraki rolled him over and kissed him, shoving his hand between Katsuki’s legs.

Chapter Text

Years ago, Tomura had seen Katsuki Bakugou bound and restrained, struggling with every inch of power in his body against the shackles to keep fighting. Bakugou had been loud through the gag and gloriously violent.

Tomura had wanted him.

For a few fleeting moments, Tomura had had him all to himself—physically at least. Mentally, Bakugou had fought with the spirit of an Alpha, defying Tomura and his offers with no room for compromise. He’d been fierce and amazing.

Tomura had still wanted him.

Later, in the smoke and ruins of the battle and Tomura’s grief had hit its peak, he continued to want Katsuki Bakugou—but this time as a pet. A toy. A trinket to kick when he got bored. His desire to control and partner with the monster hiding inside that young man took a backseat to wanting to hurt All Might and Midoriya by stealing their loved one and keeping him far away. Perhaps one day he could break Bakugou into the Villain he could have been, but it would have been enough if all he accomplished was to hurt the others who cared about Bakugou.

When Dabi came to his door with the information that his long lost Katsuki Bakugou was an Omega and needed an Alpha—needed Tomura—he’d been ecstatic at the prospect.

Tomura had expected to walk into the hotel room and be barked at by a resentful, desperate creature with no other options. He’d expected a fight. Tomura had looked forward to putting Katsuki Bakugou in his place, on his knees and acknowledging that Tomura was in charge. Tomura would demand total submission from the defiant man.

The sex would have been a delicious bonus.

But then he’d been met by a crying wreck, panicked in the shower. The screaming, bold, force that he’d seen on that first place pedestal so many years ago had turned into a jumpy, meek, nervous thing with his fear exposed on his face with nothing hidden.

It had rather killed the mood.

The sweating, wriggling mess beneath him was a trembling imitation of the “Beta” Katsuki Bakugou and it turned Tomura’s stomach in disgust.

“Please,” Bakugou whimpered, clutching to the bare mattress behind his head. He twisted the sheets, sobbing as Tomura’s fingers stretched him, slow and bored. “Please, please, please. I need—I need something. Please.”

The thing begged without knowing what it wanted. Katsuki Bakugou had turned into a broken mess.

Tomura stroked inside of Bakugou, back and forth in slow circles, fingers still dug deep between his legs. He kept Bakugou’s thighs spread by leaning on his knee, weary with the repetitive whining from the Omega.

Who knew this hid beneath that mask Bakugou wore all day? All his bark and bite was worthless if this is what he could be reduced to. Tomura felt his desire to take Bakugou back with him disperse like the smoke from Dabi’s cigarettes. Anger stirred in his chest—how dare he? Tomura had few things that kept his interest in his life and to lose one of those few precious desires made him want to scream and throw a tantrum like the old days.

He should put a stop to it all.

Bakugou’s tear stained cheeks were begging for Tomura’s fingers to dig deep until all five wrapped around his face and Tomura erased the disappointment from his sight.

“Hey,” Dabi said, voice choked. Tomura stilled his hand. The Omega on the other bed gripped tight to the mattress, arms shaking. Dabi sat straighter under Tomura’s gaze. His smooth voice trembled as badly as Bakugou’s thighs. “I don’t want to tell you what to do, but listen—the last time Bakugou had a Heat he had to go through it alone. Alone, alone. If it’s not too much trouble, could you save the slow foreplay and teasing for later? Please.”

Katsuki Bakugou had spent a Heat alone.

Tomura returned his gaze to the bed and the warm body under him. He focused properly—truly looking at Bakugou—and felt his stomach twist in a new way.

At first glance, he’d seen the glazed, aroused eyes that he’d seen so often on Dabi and he had assumed Bakugou turned into the same sex-starved beast as his Omega every month. His second look revealed the terror and dread in those red eyes. The twist of Bakugou’s fingers in the ripped fabric on the sheets came from pain, not throws of pleasure. Katsuki Bakugou was in agony, terrified that the teasing wasn’t going to end in any sort of fulfillment.

Tomura pulled his hand away, pressing his palm into Bakugou’s belly. He rubbed it back and forth and the crying grew louder as Bakugou covered his face with his arms.

Bakugou sobbed, “Not again. Please, not again.”

That changed things. Tomura hated that it did, but his disgust slowly turned to admiration once more.

Katsuki Bakugou was prepped enough. Tomura pulled off his hoodie and unbuckled his belt.

Katsuki should have known better.

Trusting Dabi had been a mistake. His heart thudded in his chest, threatening to break his ribcage as his hips burned and screamed. The Alpha his body screamed for was so close but refused to take him. Katsuki could smell the arousal but Shigaraki wouldn’t act.

This was a joke.

Revenge, even.

Katsuki’s vision blurred from the tears pouring from his eyes. He hurt. He ached. He’d been a fool. Tomura Shigaraki wasn’t there to help him, he wanted to watch him. Dabi had said there were sadistic Alpha who liked to watch Omega suffer and it made sense he’d been speaking from personal experience.

Misery loved company, because both Shigaraki and Dabi seemed content to sit there.

No amount of begging moved them.

Katsuki was going to go through this alone. Again. He squeezed his arms tighter around his head, blocking out the world as best he could. The pain laced through his body but he could bear it until he passed out. Katsuki had to.

“Breathe.” Sandalwood filled his nose and a soft touch tugged at his arms. Katsuki fought it and doubled down, turning on his side and shoving his face into the mattress. A chilled touch met his burning skin and the soothing voice floated along the side of his neck. The tug on his arms turned to petting. “You’re okay. Come on now. You’re so busy hiding under there you’ve missed you got what you wanted.”

The fingers trailed down his arms and chest, pausing over his abs. Katsuki breathed hard, following the sensation until he felt it—the warmth enveloping his waist, coming from a spot deep in his hips.

He drew his arms down and rubbed his eyes to see and zeroed in at his waist where Shigaraki had buried himself inside of Katsuki. The Alpha’s waist pulled back and thrust, hard enough that it knocked Katsuki forward—he definitely felt it that time.

That had been amazing.

Katsuki moaned into the mattress and he heard the chuckle in double, both from the Alpha behind him and from the other side of the room where Dabi spectated. Katsuki blocked it out, focusing on the new sensation shooting through him like waves of pleasure rocking back and forth with Shigaraki’s hips.

“You’re a quiet thing,” Shigaraki hummed above him. Katsuki hissed as he pulled out completely and turned Katsuki onto his stomach. He lifted him by the thighs and returned to his pattern with Katsuki on his knees and elbows. “Are you holding back or are you just that meek in bed?”

Katsuki gasped when the next thrust came twice as hard. Shigaraki’s fingers rested on the back of his throat, holding him in place as he pressed him down so that his chest and shoulders hit the mattress.

Katsuki groaned into the sheets, feeling the warmth build from his core out to every limb. Where once his touch was cold, Shigaraki’s grip burned and tickled, dragging the fire everywhere he touched. Katsuki giggled—he figured out why they called this thing a “Heat.”

“That’s not the screaming I was hoping for, but I guess it works,” Shigaraki said, nipping the edge of Katsuki’s shoulder.

“Then try harder,” Katsuki said, grabbing at the sheets. Shigaraki barked a laugh into his back and took his challenge to heart.

The intense feeling continued to grow, mind numbing and overwhelming. Katsuki continued his low groaning, his voice raising only when the pressure inside burst, shooting through him like his Quirk exploding in his veins. He collapsed onto the bed, sighing as Shigaraki rubbed his spine, switching which fingers touched him so that each digit got their fair share of time.

“All done?” Shigaraki asked, licking the shell of his ear. “You’re easy to satisfy.”

Katsuki exhaled and breathed in, feeling the pulse of his heart pick up again. His limbs shook again and he could smell the sex hanging in the air between them. Katsuki crawled up and rolled over, grabbing Shigaraki’s shoulder and yanking him down onto his chest.

“Who said you could stop?” Katsuki bucked his hips into Shigaraki and growled. “I want more.”

“That’s more like it,” Shigaraki said, shutting him up with a kiss and slamming him up into the headboard.

Tomura's chest heaved as he worked. Bakugou looked more and more like Dabi by the second as he lost himself in the haze of the Heat. His higher mind slipped away into whimpers and delighted moaning as he clutched to Tomura’s back and nuzzled every surface he could find. The affection had a different warmth to it than Dabi’s adoration, though, and Tomura enjoyed it.

Speaking of his own Omega, Tomura watched Dabi out of the corner of his eye. No longer tense, he’d fallen on his side, content to watch. Tomura had expected him to have his hand or his toys shoved inside of him, getting off to the free “show” like he’d declared earlier when he’d made it clear he was staying in the room the entire Heat.

Dabi looked relaxed and relieved, watching with half lidded eyes and an odd contentment.

His Omega cared about Katsuki Bakugou.

Tomura smiled. He would keep that in mind for later, but for now, a certain someone demanded his full attention.

“Come on,” Bakugou said in his ear. He dug his hands into Tomura’s hair, shoving his face into his shoulder. His lips scratched against Bakugou’s smoldering skin and held tight, careful to keep one finger raised at all times. It’d be a shame to end things now that it was finally getting fun. Bakugou squeezed his thighs. “I need more.”

Tomura kissed his shoulder, licking away a line of sweat. Bakugou continued to beg in his ear, demanding Tomura to take him harder. He needed more. Tomura felt selfish enough to oblige. He grabbed Bakugou’s hips and stopped their movement. A tremor worked its way through Bakugou’s body and he whined, fighting the grip. Tomura whispered, “How badly do you want it?”

“Please,” Bakugou said, nails digging into Tomura’s back. He scratched the skin, trembling with every limb. “Don’t stop. Keep moving. Please. I need it.”

“All of it?” Tomura asked. He pressed a hard kiss into Bakugou’s shoulder at the base of his neck. Tomura squeezed his thigh. “Do you want all of me?”

“Yes,” Bakugou said, burying his face into Tomura’s shoulder on the opposite side. He whispered, “Please, don’t stop.”

“How can I say no when you ask so nicely?” Tomura said.

Tomura had never considered himself traditional, but he supposed there was a first time for everything.

The bite in his shoulder hurt for a flash before it gave way to a burst of pleasure that had made his orgasm feel like a passing flicker.

The sound he made could only be described as a moan, and he held the back of Shigaraki’s neck as he dug his teeth further in. Katsuki felt a heavy liquid enter his blood, thick and slow like molasses. It burned it’s way through like good whiskey, and Katsuki wanted more of it.

He wanted all of it.

Shigaraki continued to bite down on his throat when he started to move his hips again. If the venom in his veins had felt good then, it felt even better when the sex picked up again. Katsuki lost himself in the depths of it, shouting when the second orgasm hit him with Shigaraki still wonderfully inside where he belonged.

Katsuki didn’t let go of Shigaraki when his senses returned. His lazy limbs allowed him that much, and he petted Shigaraki’s hair as the Alpha licked up the blood from his shoulder. Katsuki felt giddy and wanted.

He kissed Shigaraki hard before he passed out, drunken with well earned sleep.

Dabi joined Bakugou in his bed when Shigaraki got up to shower. He ruffled the blond hair and relaxed, pulling up his phone to check his messages while the other Omega slept. Dabi pulled the blankets up around them both to tuck them in, shamelessly cuddling.

He’d earned it after all the work he’d done.

Twenty minutes later, his Alpha emerged from the shower, drying his hair out with a towel. He looked over at the two of them and said, “Do you have it?”

“Yup,” Dabi said, raising a hand in the air. “We’re good.”

“Then I’ll see you tomorrow,” Shigaraki said. He dropped the towel and pulled his clothes on. He snorted over his shoulder and said, “Some of us still have work to do.”

“And I appreciate it, Boss,” Dabi said.

Shigaraki rolled his eyes and called Kurogiri on his phone. The butler picked him up with a flash of his Warp Gate and with that he was gone.

“What a night,” Dabi said. He shut his phone off and threw it on the nightstand. Dabi threw his arm over Bakugou’s side, spooning him and hugging him close. “You’re a lot of trouble, so you better appreciate this.”

Dabi relaxed, enjoying the quiet night while he had it.

The next day was sure to be another story.

Tomura stepped through Kurogiri’s warp and back into the hotel.

“You fucker!” Bakugou shouted, throwing the side table lamp.

Tomura ducked and it flew over his head, disappearing into the open warp gate. He heard the crash on the other side and winced, knowing he’d hear about that from Kurogiri later. The warp closed and Tomura turned back to the red-faced Omega. Dabi clung to his arm, trying to drag him back.

“You Marked me!” Bakugou yelled, holding the sheet around his waist to cover himself. The fury poured off him and he looked much closer to his proper self as he snarled, all teeth and growls. “My costume is a tank top! How the hell am I supposed to hide that?”

“Would you calm down?” Dabi asked, grabbing his arms. “Shit happens like that during Heats!”

Bakugou whipped his head to the side and shoved him off. “You said this was no strings! How is a Mark no strings!?”

Tomura had too much of a headache for this. He walked by and gave a passing Order: “Sit down and shut up for a minute, Bakugou. My head hurts.”

Bakugou sat down and snapped his mouth shut. His eyes widened and his breath hitched. He stared at Tomura, mouth open and pupils turned to pinprick with a new fear.

Tomura sat the bags of food he’d brought with him on the edge of the bed, watching Bakugou closely as his mouth opened and shut but failing to create the desired words. Dabi smacked himself in the face and fell back onto the bed, groaning to himself.

“What the hell was that?” Bakugou whispered a full minute later. He touched his throat and glared at Tomura, confused and still frightened. “I fight Orders all the time but I just did it.”

“You’re Marked, idiot,” Dabi said, breathing out. “Put two and two together already.”

“No,” Bakugou said, wincing. He held his head and hissed. “Marks force imprints. How did I forget that!?”

“How did you forget that?” Dabi asked, poking him in the back. “You seriously, seriously worry me, buddy. I’m starting to think you do need an Alpha to take care of your ass.”

“Excuse me?” Bakugou said. He got up on his knees and grabbed Dabi’s jacket. “Say that again.”

“Enough,” Tomura said. He snapped his finger and Ordered them both, “Sit down and eat. I brought dinner and you’d better appreciate it.”

Bakugou bristled in his spot next to a smug Dabi, but took the offered take out container. He ate with a scowl, but it slowly morphed into an even, neutral expression when he realized how hungry he was. The Omega ate the entire portion of curry and the second container’s worth that Dabi handed over automatically.

No one ate more than an Omega during their Heat and Tomura had been down this long road many times before.

He patted Bakugou on the head and sat on his other side with his own meal. “You can yell about the Mark when your Heat is over, because in an hour or two you’re not going to care.”

Bakugou grunted. “How many days does this last again?”

“Four to five,” Dabi said. He patted Bakugou on the back and grinned. “Welcome to the good life.”

“When this is all done, I’m going to destroy you both,” Bakugou said, stuffing his mouth with rice. He licked the sauce off his lip and pouted into the food. “There won’t be anything left for Kurogiri to rescue.”

Tomura licked his lip and laughed.

Chapter Text

Dabi thought he’d have gotten off more over the past few days with the eye candy that decorated the other bed every evening, but that first orgasm he’d had thanks to Bakugou’s shaking hands had been it.

It was hard to jack off when you were too worried about things going wrong to pleasure yourself. The thought had crossed his mind that he might get a quickie out of his Alpha if things got too boring, but Shigaraki had used all his stamina on Bakugou and had no desire to bother with Dabi.

Bakugou drooled on his pillow, one hand rubbing hard between his legs while the other pushed the dildo inside and out. He whined, hips shifting and toes digging into the sheets as he worked himself toward his third orgasm. For a guy who had barely got the tip of the toy inside of himself when he’d first tried, Bakugou had sure gotten the hang of taking the entire thing in now.

Dabi was sure that the Order helped things along.

After Bakugou’s second orgasm, Shigaraki had pulled out and Ordered the other Omega to get himself off until he was finished, just like he had every night before this one. Dabi had many a memory of Shigaraki doing the same to him and found himself amused that Shigaraki had graced him and Bakugou with equal treatment. His Alpha was a great lay for the first two times, but the Alpha didn’t have the patience or stamina to get through the entire night.

Which meant the Omega he was with were on their own—no hand service from him!

Dabi laughed as his own joke as Bakugou groaned, arching his back to get a better hold on the orange and black dildo—a gift from Dabi himself after he realized what a mess the poor guy had been on his second night.

Orders had to be followed, but they didn’t help much if the person being Ordered didn’t know what to do—their best attempts had to be good enough. And Bakugou, who had zero experience, barely knew what he was doing when it came to getting himself off. With only his hands to aid him, it’d taken the poor sap hours to finish that second night and he only managed that much because Dabi shouted tips from the other bed.

He had wanted to give more hands on help, but Shigaraki had been careless with his Order and Bakugou had been told to “finish it by himself.” By the time Dabi realized that Bakugou was going to fight Dabi if he tried to touch him, Shigaraki had already left to return to his work at the League.

That had been a long night.

On the third night, dreading another repeat of the same, Dabi had taken pity on the Omega and showed him how to use the new toy he’d bought earlier that day so Bakugou would finish faster and pass out the way Dabi knew he wanted to. Dabi had brought a few dildos and things with him for the guy to borrow—cleaned, of course—but Bakugou was a guy who needed to take something home and Dabi wasn’t parting with his stuff.

Maybe he’d use the thing once in a while when he wasn’t compelled by nature. Bakugou could use the stress relief. Dabi laughed under his breath and licked his lip as he pictured Bakugou attempting to use the dildo without the aid of an Order. He leaned his chin on his hand, legs crossed as Shigaraki played a video game behind him, barely interested in the show Bakugou was providing.

As much as he hated to admit it, it was fun being on the other side of the equation for once. Dabi had been through a hundred Heats as the one writhing on the sheets, begging his Alpha to take care of him and so dazed he barely remembered any of it. He’d never given much thought to what his behavior had looked like to the person watching him.

He’d been too out of it to care and afterwards, too happy it was over to be embarrassed.

“Kacchan” had been the total opposite. That first morning he’d woken up after sleeping with Shigaraki had been a nightmare. He’d been embarrassed from his behavior, freaked out from losing his virginity, upset that he’d been left alone by the Alpha—not that he’d admit to that one—and Dabi had almost lost his head when the Omega realized he’d been Marked.

The day after? The embarrassment and frustration that he was sleeping with the enemy still lingered, but it’d been duller. However, he’d wanted to be alone and hissed at Dabi to get out of the room and leave him be. Dabi had been happy to let him sulk and it gave him plenty of time to steal the guy a Ground Zero inspired dildo.

Bakugou had been so red finding out that a thing like that even existed that he’d been too embarrassed to complain and waited quietly until he dropped into the evening routine and cried for Shigaraki.

Rinse and repeat.

But that was all over now. Bakugou was halfway through his last night of Heat and in the morning he’d leave. Dabi was going to miss this when it came down to it. It was hot watching his Alpha screw someone else and Bakugou wasn’t too bad either for an Omega. All that Alpha appeal he had made up for it and as many times as he’d gone head to head with the guy in a fight, Bakugou might as well have been part of the crew.

Shigaraki continued to play his game on the other side, settling in to stay the entire night so he could see Bakugou off properly the next day when the Omega’s full faculties returned.

Dabi had a sinking feeling Shigaraki wanted something for doing Bakugou this “favor.”

He hoped it wasn’t too traumatizing. The whole Heat thing was bad enough and he imagined Bakugou was more than ready to be done with it all. Tomorrow morning he’d—Dabi froze and smacked his head.

He knew he forgot something important.

Tomura stood over the sleeping Bakugou.

Dabi slept on the other bed, his hand hovering over his own fading Mark under the side of his ribs. His fingers brushed it back and forth in his sleep as his chest raised and lowered with his breath.

Tomura touched the fresh Mark he’d left on Bakugou’s shoulder, finger tracing along the bubble of venom that held the wound open. For the next month, Bakugou wouldn’t be able to look at his shoulder without remembering how he begged like a dog for Tomura to take him.

He rather liked seeing it there.

For a beast waiting to be freed, Katsuki Bakugou looked rather good with Tomura’s collar around his throat.

Tomura sat on the edge of the bed and played with Bakugou’s soft blond hair between two fingers. He indulged his childish side and stretched alongside the Omega and relaxed to enjoy at least one night sleeping with his prize. He’d cleared his schedule and he was going to enjoy it.

Bakugou smelled of Tomura’s own Sandalwood and he pressed his nose his hair to inhale, reveling in it. Marks weren’t the only claims an Alpha could make. Tomura grinned as he turned to put his back to Bakugou’s side. The Omega nuzzled closer in his sleep, hugging Tomura’s waist out of instinct and a hunt for warmth. Tomura relaxed and closed his eyes, hands safe over the edge.

He fell asleep with one question on his mind: What to do with this new little toy of Dabi’s?

Katsuki woke to an emptiness strangling his heart and pain so strong it drew tears.

A hand slammed over his mouth and his eyes darted to the side to see Dabi, hovering over him with a finger to his mouth to silence him. He whispered, his gaze darting to the body on Katsuki’s other side, clearly not wanting to wake Shigaraki. “You’re okay. I promise. Despite what it feels like, the the world is not ending and you’re not going to die of shame.”

Dabi’s hand didn’t move, his fingers growing wet with Katsuki’s silent sobs. He clutched at his stomach, fingers digging in.

“Congrats,” Dabi whispered, “you’re not pregnant, though I’m sure you would rather have condolences at the moment.”

Katsuki’s nose bumped into Dabi’s hand and he shoved at the limb.

“Are you going to be quiet? Shigaraki doesn’t know shit about this and I’d rather it stay that way,” Dabi said. He kept his voice low, fingers digging into Katsuki’s cheeks. “Can you do that?”

Katsuki nodded.

Dabi lifted his hand, eyes still on Shigaraki’s back. His wheezing breaths filled the room and his fingers twitched as they hung in the air. Katsuki sat up, slow and stared at Dabi, hands still over his stomach.

“What is this?” He asked. Katsuki covered his lower mouth, still crying. “Why do I feel like such a failure?”

“This would be the Post-Heat, in other words: it’s Nature’s way of punishing us if we haven’t brought a litter of brats into the world,” Dabi said, voice bitter. He licked his lip and shrugged. “The longer you go without getting pregnant, the more it hurts—kinda like how Heats get worse when you’re older.”

Katsuki stared at Dabi. He hadn’t thought being an Omega could get worse, but he’d been mistaken. He breathed hard, staring at the filthy sheets and shook his head. “What the hell?”

“I ask myself that every time,” Dabi said. He patted Katsuki’s shoulder and rubbed it on the back, his stitches and scarred skin scratching the surface. He lay next to Katsuki and crossed his feet at his ankle. “On the bright side, you know immediately if you got knocked up or not, so that’s always a plus. But honestly? Alpha do not understand this and they’re never going to, so it’s best they just stay out of it. You’ll learn to hide it in time and it gets easier to suffer through.”

Katsuki slowly lay down and covered his face. “How do you do this every month?”

“You get used to it,” Dabi said. He turned and tugged Katsuki into a cuddle. He pressed his face into his side. Katsuki wanted to push him off, but the comfort felt nice while his insides still screamed of his failure and grief. “Not the best thing to hear, but it’s true.”

“Perfect,” Katsuki mumbled.

“Go back to sleep,” Dabi said. He nuzzled closer and breathed. “Enjoy your final day off.”

Katsuki shut his eyes, but he couldn’t sleep. Despite what Dabi had said—despite knowing it was an instinct response—he couldn’t shake the despair that coated him. He spent the next hour sandwiched between two Villains with his arms wrapped around his stomach, counting the minutes to when the sinking feeling would go away.

Tomura sat up to find Dabi cuddled into his side. He patted his Omega’s head before glancing around the room. Bakugou’s things were still on the other bed, so he hadn’t ran off with his tail between his legs.

He listened.

The shower burst on, the thin walls giving away the location of Katsuki Bakugou.

Tomura slipped out of bed and threw a blanket over Dabi’s side. He stepped across the room and pushed open the small bathroom door. Steam flooded the room and the shower ran on full blast, the deafening sound of water smacking into the shower curtain and body behind it.

He tapped his knuckle on the shower curtain, grinning as he watched Katsuki Bakugou jerk in surprise one last time before snickering. “Want company?”

“No,” Bakugou growled. “Get out.”

Tomura snickered, tugging the curtain back to peak on the other side. Bakugou’s skin looked red, flushed from the steam of the shower and his own embarrassment. Tomura pulled the curtain open further. “You don’t want the chance to compare regular sex to Heat sex?”

Bakugou slammed the curtain back where it was and shouted, “No!”

“You’re such a brat,” Tomura said. He pulled his shirt over his head and dropped his shorts on the floor. He shoved them with his foot to the side and ripped the curtain back open. Tomura could only handle so much disobedience after giving up his precious time to “save” the hiding Omega. A simple Order would do the trick: “You will share the shower with me. At the rate you’re going, the hotel is going to run out of hot water.”

Tomura flicked the Mark he’d left on Bakugou’s shoulder as he ducked under the hot water. He gasped at the scalding temperature, but refused to jump back. He let it burn and reached around Bakugou to grab the soap. The Omega had murder written over his face as he gritted his teeth and stared down Tomura, but shared the space—he had no other choice.

“If you keep glaring like that, I’m going to make it worse,” Tomura said, lathering the soap on his hand. “I could make you wash my hair or any of the other parts you’ve made a mess of this past week.”

“And you called me the brat,” Bakugou said. He turned away and went back to scrubbing his hair under the shower, the suds dripping down his neck and shoulder. “Next time we see each other, I’m going to blast that smile right off your face.”

“I doubt that.” Tomura touched a finger to Bakugou’s spine and dragged it down until he ghosted his fingers over his hip bone. He felt the shiver under his skin and leaned closer, blowing on his pretty Mark. “Next time we see each other, you’re going to remember the best sex of your life.”

“Like I said,” Bakugou said, holding his ground and narrowing his eyes. His heavy breathing interrupted his sentence while his palms smoked at his side. “I’m going to blast your face off.”

Tomura patted Bakugou’s cheek with four fingers. “You’ll change your mind.”

The fuming Omega didn’t answer and turned his back. He finished rinsing out his hair and got out of the shower, grabbing a towel on his way. Tomura remained under the shower water, successful at getting under Katsuki Bakugou’s skin.

He reminded himself to thank Dabi later for such a delightful gift—Katsuki Bakugou had been worth the wait.

Chapter Text

“How much do I owe you for the room?” Katsuki grunted, shoving his things in his duffle. He glared at Dabi as he shoved the orange and black dildo in with his dirty clothes but didn’t have the energy to throw it out the window. He zipped the bag up to hide the toy away and yanked it off the bed. “It couldn’t have been cheap to rent the room for a week.”

“Dude, we’re Villains,” Dabi said, blowing a puff of smoke from his cigarette. He bit the stick between his teeth and grabbed his and Shigaraki’s things, slipping the straps of both bags through his arms to hang off his back. “No one’s paying for the room.”

He snapped his fingers and lit the bed on fire with a grin. Katsuki yelped and jumped back, clutching his duffle bag to his chest. Shigaraki laughed from the side and put his hand against the opposite bed, crumpling it into dust.

“And in a minute, there won’t be any evidence we were here either,” Dabi said. Katsuki stared at the ceiling where the sprinkler system had yet to go off, despite the smoke in the room. Dabi noticed him looking and shook his finger back and forth. “I cut the power to the emergency systems earlier.”

“You can not light this hotel on fire. We aren’t the only people in the building!” Katsuki yelled back. He grabbed Dabi’s shirt and pointed at the flames. “Put those out!”

“I’m only burning the room,” Dabi said, holding his hands up. “Don’t freak out. The sprinklers don’t work but the walls have fireproof insulation. It’s fine. You should be grateful we’re doing the extra service of helping cover for your ass.”

“We aren’t leaving until that fire is out,” Katsuki said, crossing his arms.

Dabi looked at his blue flames, moving their way from the blankets on the floor to the curtains and then threw another fireball toward the bathroom. It lit the towels on fire, crawling up the plaster of the walls until everywhere had something ablaze. “Yeah, I light things on fire, not put them out.”

“We’re not waiting,” Shigaraki said, staring at his phone. He grabbed the back of Katsuki’s shirt and yanked, tossing him through Kurogiri’s warp. Shigaraki and Dabi followed him and they stepped out onto the street with one additional party member as Kurogiri stood silently behind his master. Shigaraki put his phone away yawned into his palm. “I’m sure they’ll figure out there’s a fire.”

Dabi threw an arm around Katsuki’s shoulder and tugged him into a half-hug. “For someone who breaks the law every day he keeps working as a Pro Hero, you sure are a stickler for following the rules.”

“What I’m doing doesn’t hurt anybody or damage property!” Katsuki shoved Dabi’s arm off his shoulder. “It’s not even remotely the same.”

“The law’s the law,” Dabi said, licking his lip. He shoved his hands into his jacket pockets and shrugged. “The authorities don’t see a difference.”

He wasn’t going to get anywhere arguing with Villains and he wasn’t in a position to fix this either.

Katsuki would check on the hotel later on his next patrol and if the damage went past that one room, he’d hunt down Shigaraki and Dabi personally.

He squeezed his bag handle. “Are we done here? Because I’m going home.”

“You don’t want to stop in there first?” Dabi said, pointing behind him with his thumb. Katsuki recognized the door as the Doc’s place and cursed himself for not paying more attention to where the warp dropped them off. “I figured you’d be racing to see him after that last week.”

“I don’t need an entourage for that,” Katsuki said.

“I think someone who’s future depends on our silence and cooperation would be kinder,” Shigaraki said, messy hair falling between his eyes. “You haven’t even asked what you owe us for my services.”

“Yeah, you don’t think we did this out of the kindness of our hearts, did you?” Dabi asked, throwing a hand out.

Katsuki clenched his fists.

He refused to owe them anything.

Katsuki called their bluff.

“I’m going in there and getting my suppressants,” Katsuki said, walking past them. He intentionally smacked his shoulder into Dabi’s side. “Starting tomorrow we’re enemies again.”

Shigaraki laughed behind him and snapped his fingers. Kurogiri opened the warp and he took a step through. He raised his hand and waved. “See you next month, Katsuki. I look forward to having you beg for me again and if you’re good, I’ll even give you another Mark.”

The warp closed behind him, leaving Dabi and Katsuki alone outside of the Doc’s shop.

“That’s adorable,” Dabi said, lighting a cigarette. He pinched Katsuki’s cheek, cooing with a fake, cheesy grin. “He really likes you.”

Katsuki punched Dabi into the wall and entered the Doc’s shop without knocking.

“Your face is more purple than usual,” Shigaraki said, playing his game from a beanbag chair, his leg hiked up on the side. “Is Katsuki still pouting?”

“Yup,” Dabi said, collapsing in the chair next to Shigaraki. He rubbed the bruise on his cheek, but smiled all the same. He kicked his feet up on the table behind Shigaraki and threw his arms over the arms of the chair. “I think you embarrassed him by using his first name.”

“I should call him that next time we see each other,” Shigaraki said, mouth twitching as his fingers clicked on the game console. “He’ll either start hitting harder or freeze up.”

“Fifty-fifty chances make everything more exciting,” Dabi said, slouching into the couch.

Shigaraki continued the game. “He get his suppressants?”

“Yeah,” Dabi said.

Along with a lecture.

“I shouldn’t in good conscious be giving you more of these so soon,” the Doc had said, giving Bakugou the pills he’d paid for a couple weeks ago. He grabbed Bakugou’s wrist and squeezed. “Your blood test results were fine, the venom from the Mark and the Heat helping tremendously, but there’s still damage that’s been done. You can’t keep going like you have been and you have to take breaks.”

“Sure,” Bakugou had said, staring at the ground. Dabi could tell from where he sat on the exam bed next to him that the other Omega was lying through his teeth. Bakugou clutched the bottle of pills, hard enough that the plastic whined. “I can do that.”

“I’m serious, Ground Zero,” the Doc said. He kept his hold and said, “You should start thinking about the future and an escape plan. One day, these pills won’t work or you’ll get caught and then where will you be?”

“I’m not going to get caught and I’ll be more careful,” Bakugou said. He shoved the pills in his bag and put his hand over the Doc’s. “I promise.”

“Just be safe, kid,” the Doc said. He waved his hand over his shoulder and said, “Now get out of here before I change my mind.”

“Thanks, Doc,” Bakugou had said.

He and Dabi had parted ways after that, with only a passing “See you” given between them.

“It’s all a waiting game now,” Shigaraki said, dropping his head back. He rested it on Dabi’s shin and smiled wide. He shut the game off and dropped it on the table behind him, clattering it near Dabi’s leg. “Katsuki’ll be back. He’s mine now and he knows it.”

Dabi closed his eyes and breathed out. “I’m taking a nap.”

“Lazy,” Shigaraki said.

He got up and ruffled Dabi’s hair before excusing himself from the room, scratching at his side. He yelled for Kurogiri as he entered the hallway, saying something about wanting a drink and to get Twice and Toga for a new plan.

Dabi clasped his hands over his waist and relaxed. After the week he just had, he earned it.

He might as well do it while he could. When Bakugou came back, things were certainly going to be lively.

Katsuki trudged up the stairs to his apartment. Blessedly, the hour was late and everyone was long asleep and the hallways were empty. Katsuki had no desire to see another person until after he’d slept for two days.

Then maybe he’d call Kirishima and give him an update.

He groaned as he turned the corner on the stair landing one floor before his. Katsuki had to deal with everyone he’d blown off for the week sooner or later. Deku, Kirishima, Kaminari, Sero, Ashido, and all those other idiots were going to give him hell for dropping off the face of the planet with only a “I have the flu” for an excuse.

Katsuki hopped up to the top of the last landing and put his hand on the door handle. He rested his forehead on the stairwell door and breathed in.

That wasn’t so bad.

It was nice having friends that cared so much. Katsuki had worked hard to get to this point in his life, and if dealing with monsters in dark alleys is what it took to keep things the way that they were, he’d do it.

He opened the door to his floor and yawned into his hand. Katsuki could save his worries for another day. If he stopped thinking about Shigaraki and Dabi and everyone else for the moment, he felt pretty good when it came down to it.

He felt lighter and satisfied to have gotten over the biggest hurdle in his life. His Heat no longer haunted him the way it had been—he’d survived it twice, he could survive it again as many times as he needed.

As Katsuki reached the end of the hall and turned the corner to reach his room, he stopped.

Deku sat crosslegged with his back against Katsuki’s door, hands in his lap. His hair had gone limp with grease, and he slumped forward, breathing slow and even. The bags under his eyes were as dark as bruises and Katsuki felt a tug of something in his chest.

He’d done that.

Katsuki dropped his bag on the ground near his legs, unsure of how to approach the worried Alpha. He had no idea that Deku would have taken his disappearance this hard, though he should have known better.

The last time he’d disappeared with Shigaraki, it hadn’t gone so well for Deku either.

Deku looked up at the sound of Katsuki’s bag hitting the ground. His eyes widened and watered, the tears spilling over onto his cheeks. “Kacchan!”

He ran from the door, tackling Katsuki around the waist. They crashed into the wall and Katsuki grabbed his back from instinct, finishing the hug. “Deku.”

“I was so worried, Kacchan!” Deku shouted, clutching hard. He dropped his face into Katsuki’s shoulder and nuzzled him. Deku’s tears wet his shirt, and he felt the rise and fall of the Alpha’s chest as he struggled to breathe. “Kirishima said you were sick but wouldn’t tell me where you were because he didn’t know. No one knew where you were, Kacchan! You were gone for so long and I—”

Deku cut himself off, inhaling.

Katsuki grunted as Deku’s hold tightened, the grip bruising his skin. He looked down and sucked in a breath as he watched Deku’s pupils narrow into thin slits.

“Kacchan,” Deku whispered. Katsuki went limp in the hold, natural instincts screaming at him to submit and for once, he listened. Deku’s grip tightened. “Why do you smell like Sandalwood?”
