Bakugou spent most of his free time practicing using his quirk and building up his endurance and strength. Truthfully, he wanted nothing more than to spend the day with his boyfriend, but it was important for them to spend some time apart. It was necessary to Bakugou that he stay on track with his schoolwork and his training to become the number one hero someday, and he couldn't let himself lose sight of that.

Still, Kirishima was the only thing his mind would focus on for hours. He hoped he was having fun with friends. The redheaded idiot had eventually agreed to just wear his sweatshirt normally, to Bakugou's relief, but they were both still worried about what their friends would think if they saw the hickey. Then again, they just might be stupid enough to ignore the marks altogether.

Despite his best efforts Bakugou couldn't keep him out of his mind, so he sent him a text. It was just a simple, casual text to see how he was doing. But, before long, they were texting each other back within seconds of each other and constantly keeping in touch. So much for a day of solitude and training for Bakugou. After only about an hour of training he ended up just sitting in the grass hunched over his phone, soaking in every single message as soon as it came in. In the back of his mind he was vaguely aware of just how hopelessly smitten he was with this boy.

Before long the day was drawing to a close and Bakugou was making himself supper in the dorm kitchen when Kaminari and company got back. The door flew open and all at once the quiet and peaceful common area was filled with the noisy, boisterous group as they poured inside. They were all laughing hysterically at some inside joke that Bakugou didn't know or care to know. Instead his eyes narrowed, and he continued with his cooking in somber silence and did his best to ignore them completely.

"Alright, I'll catch you guys later," Kirishima called after the group as they started up the stairs to their dorms. Then he snuck up behind Bakugou and wrapped his arms around him in a big hug as he rested his head on his shoulder. "Whatcha making me this time?"

"You're ballsy, aren't you?" Bakugou snarled. "If those idiots come back we'll be caught. And I'm not making you anything tonight. I only made enough for one serving this time."

Kirishima smiled. "I already ate. I just wanted an excuse to hug you."

Bakugou elbowed him in the ribs, making Kirishima grunt in pain and back off. Bakugou said after a second, a little more lightly, "So, did anyone see our little secret?"

"Our..." Kirishima paused a minute as he tried to piece together what he had asked. "...Oh that! No, your idea for me to wear my sweatshirt was a really good idea."

"I thought so."

They lapsed into silence for a while after that, and eventually Kirishima went over to lean on the counter and play on his phone. He smiled every once in a while, probably at a stupid message from Pikachu or Tape Arms or that pervy grape kid. Bakugou would never admit it but watching him smile was the highlight of his night. He watched his lips curl into an easy smile, showing off a row of perfect teeth while his eyes sparkled with humor as he glanced over a new message.

His mind ended up drifting off to thoughts of what that perfect mouth tasted like, how it felt as their mouths came together and they lost themselves in each other's touch. Before long Bakugou's mind drifted back to thoughts of that morning, eventually picturing Kirishima in the shower again with water streaming down his back and along every curve of his perfect body, caressing his smooth skin.

"What are your plans for tonight?" Kiri asked casually.

Dammit, Bakugou was caught staring. With a nervous smile he adjusted his position to hide the front of his pants, just in case. "Well I only planned far enough ahead to decide that I would eat something. I guess after this I'm free."

"Then mind if I sleep with you again tonight?" Kirishima asked, then suddenly blushed and scrambled to say, "I didn't really mean like that, just that I actually slept really well in your bed and I would kind of like to do that again and I'm kind of a cuddly person anyway to be honest and I really liked sleeping next to you...."

"You're cute when you're flustered," Bakugou commented as he turned back around to check on his food, while also hiding the little smirk on his face as he added, "Sure, you can sleep with me tonight."

Kirishima asked nervously, "Do you mean, like, in your bed, or..."

Bakugou pretended not to hear him as he said, "I still have to finish this and work on some stuff down here, but I'll be up there in a little bit, Red."

"Alright," Kirishima said as calmly as possible, though he was still blushing red as a tomato as he all but raced up the stairs.

After he had finished his supper and washed the dishes Bakugou made his way up to his dorm, a little nervous as he wondered exactly what he would find when he got there. He wasn't sure that Kirishima expected them to get up to anything again that night and would be waiting for him in bed, or if he was already fast asleep. Kirishima did seem almost opposed to it when he tried to backpedal after asking to sleep with him, but he did let himself get his hopes up the slightest bit.

When he got to his room he hesitated and took a deep breath before opening the door. The light was on, and an extra pillow rested beside his on the bed, but there didn't seem to be any other indication that his boyfriend was present. Then he heard the bathroom faucet turn on and pushed the door open to see Kirishima standing there in his pajamas brushing his teeth.

"Make yourself at home, I guess," Bakugou chuckled. Kirishima just smiled in response, showing his teeth covered in foamy toothpaste.

Bakugou chuckled again at the sight then squeezed into the bathroom behind him to brush his own teeth, but Kirishima was taking up all the space in front of the sink. Then he got an idea for how he could try to gauge the mood of the night. Wordlessly he stepped behind his boyfriend and reached up and forward to grab his toothbrush from the cabinet above his head, pinning Kirishima to the sink with his hips as he reached.

The redhead paused a moment in his brushing. Bakugou took that as a good sign and struggled to hide his smirk as he drew back a bit, then leaned forward again to grab his toothpaste from the cabinet next. Kirishima paused another moment, then bent over with an exaggerated motion, bumping against Bakugou's crotch as he spit his toothpaste out. He watched the little bastard smirk in the mirror as he gasped in surprise at the wave of pleasure that shook his body.

"Did you steal my quirk?" Kirishima asked as he shamelessly rotated his hips, grinding against Bakugou.

"You know I didn't," the blond boy growled as he set his toothbrush and toothpaste down on the sink and used his now free hands to grab Eijirou by the waist.

"Don't you need those to brush your own teeth?" Kirishima asked.

Bakugou shrugged and started kissing his shoulder. "It can wait. Or you can...share some of your toothpaste with me."

Kirishima laughed at that, mostly because it sounded a little ridiculous, but he wasn't about to question it. He spun around to kiss Bakugou, and the blond boy joined the kiss eagerly while keeping him pinned to the sink with his hips. Katsuki let his hands travel under his shirt to carefully trace every line in his rippled torso.

He couldn't wait long before pulling the shirt off entirely and tossing it aside, exposing Eijirou's skin to the cool air. Then Bakugou couldn't resist: he slipped a hand under the waistband of his pants and cupped his ass, earning a startled gasp from him. But his reaction didn't seem to be any sort of protest, so Bakugou gave it a little squeeze and Kirishima whimpered into his mouth.

The redhead broke away from the kiss with a coy smile on his face as he asked, "Would you like to...move this to your bed?"

"After you," Bakugou answered.

He followed Eijirou back to his bed, then pushed him onto it face-first with a sly smile on his face. Before Kirishima even had time to react Bakugou was straddling his thighs and pinning his hands to his side, letting his dominant temperament show for a moment. He started to grind against Kirishima's ass, squeezing his wrists tight as he did. But while he may have been acting a bit brutish and harsh, he was sure to monitor his boyfriend for any sign that he wanted him to stop. He leaned down and traced tender kisses down his neck and over his shoulders. But if anything, the display of force seemed to have him in even more of a lust-filled haze than usual, which encouraged Bakugou even more.

"You want me to ride you again..." he started in a low, smoky voice. He kept his lips just behind the other boy's ear, not close enough to kiss him but just enough to feel his hot breath on the sensitive spot and desperately crave that soft touch. After a few seconds he continued, "...ride you until you scream my name."

He bit Kirishima's ear a bit roughly then and he groaned, "Yes...please."

But Bakugou thought of something and murmured in his ear, "But I want to try something a little different tonight, if that's okay with you."

"Mm, what did you have in mind?" Kirishima asked weakly.

Katsuki looked like an actual cat as he nuzzled his boyfriend's head and said in an uncharacteristically soft way, "I want to see your face tonight. I want to look into your eyes when you cum for me."

Even in the dark he could catch the bright red that blossomed on his cheeks. He may have been behind him and Kirishima was facing away, but just the slightest glimpse of his face from the side and he could see the intense blush. It riled Bakugou up again and he smirked as he continued to grind against him.

"You're such a big, tough guy, aren't you?" Bakugou said. "I bet you completely fall apart once you've been thoroughly fucked."

Kirishima bucked his hips roughly, making Bakugou gasp. He snapped, "I'm still man enough to tell you to fuck off."

Bakugou pushed him back down roughly and said in a gruff but not entirely unpleasant tone, "I know you're a real fucking man, Eijirou. Fuck—you're the manliest person I know. I don't deserve you." He let go of Kirishima's wrists to move his hands up along his arms and down the lean muscles of his back reverently.

Hearing that alone was enough to make Kirishima just about lose his mind. With a light laugh he answered, "That's all I wanted to hear."

Then he relaxed into the mattress, letting his boyfriend's hands explore his back freely. He could feel just how aroused Bakugou was, and the thought of getting fucked senseless made him painfully hard as well.

"So...do you want to try my way?" Bakugou's smoky voice murmured in his ear.

"Yes," Kirishima answered at once.

The thought of looking into Bakugou's eyes was an appealing idea. The delicious, barely-hidden sounds he made were one thing, but how did he look when he cried out his name as his orgasm rolled through him? Did his eyes burn with that fiery, explosive passion that he had fallen for? He supposed it was a shame that he didn't know, and he was determined to find out.

All at once he felt the pressure leave from his back and turned over in time to watch Bakugou pull his own shirt off, openly staring as piece by piece his beautiful torso was exposed to him. He let his eyes trail up his abs and over his perfectly sculpted, heaving chest. The blond boy tossed his shirt aside and smirked when he noticed him staring. He moved his hands down to his pants but Kirishima stopped him.

With his own hands Kirishima started to unbutton and unzip Bakugou's pants. His movements were so agonizingly slow that by the time he finally got around to pulling his underwear down it looked like Katsuki wanted to kill him. But he stayed stock-still despite the raging fire that threatened to consume him. Or at least, he didn't move until Kirishima's hand wrapped around his cock and gave it a few small strokes. He doubled over at once as he was overwhelmed by the sudden wave of pleasure that overtook him.

"Fuck, Eijirou," Bakugou groaned over his shoulder. His mind was filled with a cloudy fog that muddled his thoughts and he began to lose himself in the glorious sensations that threatened to overwhelm him. When the movements slowly came to a stop his eyes narrowed and he pulled back to glare at Kirishima.

"Can't have you finish that soon," Kirishima said roguishly. "I was told I could look into your eyes as you had your way with me tonight."

Bakugou sighed and grumbled, "Then lay down, Shitty Hair."

He didn't wait for him to lay down himself but pushed him back roughly and made short work of his pajama pants and underwear, tossing them aside roughly. Then he reached into the top drawer of his dresser to take out the bottle of lube and a towel that he chucked at Kirishima. The redhead looked at it in confusion.

"Put it under you, idiot," Bakugou grumbled, though his smile hinted that he didn't mean it unkindly. Insults were more of a term of endearment for him sometimes. "I had to wash these sheets today because of you, remember?"

"Right," Kirishima chuckled.

He rolled over and spread the towel out briefly before settling back down into his spot. Then with a hungry smile Bakugou climbed into bed and at once was all over him. They kissed each other deeply, with their hands reaching for their hair or wrapping around their bodies until soon they returned to their desperation and lust. The feeling of their chests brushing, of feverish skin touching made them both crave more contact.

Bakugou broke away briefly to grab the lube and spread some over his fingers before returning to kiss him again. He hooked one of Kirishima's legs over his hip to give him a better angle as he pressed one finger into him, slowly building up his tolerance. Occasionally Kiri let out a moan or whimpered into his mouth, but otherwise gave no significant response to the pressure.

Once he was sure he was ready, Bakugou lifted his legs up higher and moved his lips down along his jaw to listen to the sweet noises Kirishima made as he pressed into him slowly. Their bare chests heaved together as he forced himself inside as much as he could dare. Kirishima gasped, then let the air out again in a long groan.

Bakugou continued to hold one of his legs at a good angle while he used the other to push himself up so he could look at his lover's beautiful face. Kirishima's eyes were closed, his cheeks flushed and mouth open as he got acclimated to the pressure inside of him.

Bakugou hadn't anticipated what a turn-on it would be to see his face as he did this, and it took every bit of his dwindling willpower to avoid focusing on his own pleasure. He watched Kirishima's face carefully as he worked himself deeper, pausing every time he saw the slightest glimmer of pain cross his face. When he was finally as deep as he could go he paused and leaned down again to pepper his neck and jaw with soft kisses until his breathing began to settle down a bit.

"You should let me see your eyes," Bakugou murmured before pushing himself up at arm's length again.

Kirishima obeyed at once, opening his eyes to see Bakugou looming over him with a genuine smile on his face. It was so rare, so unusual that he looked so real and human. For once murder clearly wasn't the only thing on his mind. And yet his posture, even his figure alone radiated raw power and dominance. His body looked so lean and fluid normally, but the exposed skin he normally kept mostly concealed by layers of clothes was bulging with powerful muscles.

He had the strength and the means to easily overpower Kirishima, as he had proved time and time again, but still he waited and watched Eijirou's every move with careful concern. This boy—no, this man—was so many steps out of his league, he thought, and yet here he was nonetheless. He cared about Kirishima, saw something in him when normally he showed no emotion for anyone. And then Kirishima remembered that, whether he deserved him or not, this was his man to touch.

Kirishima looked up into his eyes as if hoping to find some kind of sign that he had his permission, but the only thing he saw was the same look of concern with a thin layer of lust that he kept veiled behind those eyes. His look was guarded and not entirely honest. Kirishima reached a tentative hand up to gently touch his collarbone and then drifted down along his heaving chest, the pronounced lines of his abs, and then back up, feeling him shudder slightly at the touch.

When he looked back up into his face, he saw that Bakugou's eyes were following the movement of his hands with bated breath. He even bit his lip a moment before letting out his breath in a long sigh that was unmistakably similar to a low growl. He shuddered at the touch again as Kirishima's finger gently circled his nipple.

"I don't think I'm the only one who can be completely unraveled," Kirishima murmured with a devilish smile. He knew his words would sound like a challenge. He was playing with fire now.

In response Bakugou drew out a bit and snapped his hips forward roughly, making Kirishima gasp loudly at the sharp pain, but also at the sudden rush of pleasure. For a split second there was a glimmer of worry in Bakugou's warm eyes, but it was quickly replaced by a look of arrogant pleasure.

"You liked that, didn't you?" he asked with a self-satisfied smile on his face as he did it again, harder.

Kirishima gasped again but smiled back, baring his own sharp teeth as he answered, "I have a high pain threshold, Kat. Maybe you've been too worried about me this whole time." He brought his hands up to cover Bakugou's shoulders, giving them a firm, reassuring squeeze to prove his point while also getting some more of the contact he desperately craved.

"You sure you mean that?" Bakugou asked as he started a rhythm of slow yet somewhat rough thrusts.

The stupid grin disappeared completely from Kirishima's face. He threw his head back against the pillow and closed his eyes as he moaned, "Fuck, yes. Yes, Katsuki."

At that sound Bakugou couldn't hold himself back anymore and quickly increased his pace. He watched with smug satisfaction as Kirishima's face changed with every thrust with a mixture of pain and pleasure, with emphasis on the latter. It looked like he could hardly get enough breath to speak, or make any noise for that matter, but still he whimpered and moaned and panted when he could. At least his feverish hands over Bakugou's back told him that he was loving every moment of it. His scarlet hair was drenched in sweat and stuck out all over the place, framing his perfect face as it contorted with rushes of conflicting emotions. It was absolutely beautiful.

"Kat," he panted weakly, "I can't...last...much longer."

"Open your eyes," Bakugou commanded.

Kirishima obeyed at once. His pupils were dilated, both eyes glowing with sheer euphoria as he looked up at him. Bakugou took his member in his hand and began to stroke, watching as his face lit up even more at the sensation. His hands dug into Bakugou's back like claws as he cried out his name, loudly. He panted heavily and groaned as he came, spilling out over Bakugou's hand and onto his own stomach.

Bakugou wiped his hand off on the towel before dropping it to his side, holding himself up as he continued in pursuit of his own orgasm. He looked back into Kirishima's smoldering eyes, down his sweaty face to his gaping mouth, and further down to the mess that coated his stomach, and he was pushed over the edge himself.

Kirishima watched his eyes as his own climax began to fade, but Bakugou's face alone was almost enough to make him start all over again. He was a sweaty mess, his face shining with ecstasy and his eyes burning with a wide range of emotions. He was staring deeply into Kirishima's eyes as he came, and they shone intensely with a mixture of lust, adoration, and overwhelming pleasure.

When the rush of his climax had completely left his body Bakugou slumped forward, pressing his forehead to Kirishima's as he struggled to come back to his senses, letting their heavy, feverish breaths mingle together in the shared space between them. He couldn't get that beautiful image of Kirishima's face out of his mind, and as soon as he had the tiniest bit of breath back he started to kiss his jaw, though his arms were visibly shaking from the effort to hold himself up in that position.

"Fuck," Kirishima breathed as his heartrate gradually began to settle. "That was amazing, Kat."

Bakugou let out a breathy laugh against his neck and mumbled, "Really?"

"You didn't like it?" Kirishima asked disappointedly.

"Hell yeah I did," Bakugou countered at once as he lifted himself up to make eye contact again. He was still struggling to regain his breath as he muttered, "I just wasn't...sure you would be okay with that. I was worried you...wouldn't like it."

"I told you man, high pain threshold," Kirishima laughed.

"I'll keep that in mind," Bakugou responded as an almost threatening smile played at his lips.

He stayed in that position a little while longer to catch his breath, staying close to Kirishima for as long as possible in their own world with their fiery eyes locked and bodies pressed together. With a sigh he finally rolled away onto his back, then let out a little hiss as he felt sparks of pain shoot up his back.

"What is it?" Kirishima asked worriedly.

"My back," Bakugou answered. "It doesn't hurt that bad, but it surprised me."

"Let me see."

Bakugou sat up with his back facing to the other boy but it was hard to see in the darkness, so Kirishima leaned over the bed to grab his phone and turned on the flashlight to see better. When he saw what it was he felt heat rise to his cheeks and let out a little sheepish chuckle. It turned into a louder snicker as he snapped a picture of his back.

"What the hell!?" Bakugou growled angrily. "Tell me what it is before you start taking pictures of me dammit!"

Kirishima propped himself up on his elbow as he handed Bakugou his phone, still snickering quietly to himself. The blond boy snatched the phone away and looked at the pictures, confusedly at first. Then he realized what he was looking at. A number of dark red scratches stretched from his shoulders to a good way down along his back.

"Are they bleeding!?" Bakugou demanded. He reached back to touch one of the scratches and drew it back to see a tiny splotch of red on it. "My mattress has seen so much abuse in just over 24 hours. It's innocence, and cleanliness, are too far gone now." He groaned. So much for the effort he went through to keep it clean.

Kirishima just laughed happily. "I think it fits."

"What does?"

"Your scratches, my hickeys," Kirishima said, then bared his neck where a new bruise was forming. "I guess we just made sure we belong only to each other now."

"Cheesy bastard," Bakugou grumbled.

Kirishima stuck his tongue out at him but couldn't help giving him a big smile. He put a hand on Bakugou's shoulder and gently pulled him down so that they were laying side by side. He intertwined their fingers and placed a kiss on the other boy's calloused hands before letting them rest over Bakugou's chest.

"It's not like I did it on purpose," Kirishima said after a while. "Means you did something right."

"Did I?" Bakugou chuckled. He honestly didn't mind that much anymore; it was oddly comforting to know that he had a mark to remind him what they had done.

"Yeah you did," Kirishima answered a minute later.

There was a long but easy pause before Bakugou added, "Well, remind me to do it again." But Kirishima frowned, so Bakugou asked softly, "What's wrong?"

The redhead answered sadly, "The weekend is almost over. Everyone is gonna start coming back tomorrow."

"Next weekend then," Bakugou assured. "We can go to your house if you think your mom wouldn't catch us, or I could rent out a hotel room for a night, I don't care."

"Why not your home?" Kirishima asked.

Bakugou actually laughed as he answered, "No way. My room is right next to my parents' room. If my mom knew you were my boyfriend, let alone that we were having sex, she might actually kill you, or me, or both of us probably."

"Then I could probably have you come to my house for the weekend," Kirishima laughed. "But I think I should warn you: she's guessed for a long time that I might be gay so she's going to guess that we're together anyway. But my room is on the other side of the house, so I don't think she would be able to hear us."

"Good enough for me," Bakugou said simply.

With a heavy sigh he pulled Kirishima closer around him to snuggle closer, trying not to wince at the stinging pain all over his back. That boy had some ridiculously sharp claws, it would seem.

Eijirou was happy to snuggle up next to him but was still frowning. Eventually he muttered, "Still, we have to survive a whole school week without doing any of this again."

"Well I don't want this to be the only thing we care about and you shouldn't want that either. Raging teenage hormones won't last forever. This is amazing but...I want to be sure there's more to us than sex too."

"There is," Kirishima assured him. "But that doesn't mean we can't enjoy this too, right? And you're really hot when you get all smart and responsible."

"What do you mean?" Bakugou asked as his eyebrows furrowed skeptically.

Kirishima smiled as he replied, "You're always so mean to everyone that it's easy to forget how smart and responsible you are sometimes. It seems like I'm the only one who really cares to notice. Everyone else gets scared away but I always knew there was more to you than just anger."

"No there isn't," Bakugou growled, sounding more like a pouting little kid than anything else. "I am an unstoppable force that will watch the world burn if it means I can rule over the ashes."

Kirishima let out a little chuckle and teased, "Nope, you're a responsible, ambitious, intelligent man who will be as selfless as a hero as he is as a boyfriend."

"Go to sleep, idiot," Bakugou answered in a gruff voice, though he had a broad, warm smile on his face.

Kirishima returned the smile as he snuggled up closer to him, resting his head on Bakugou's shoulder while the other boy's arm curled around him comfortingly. They were quiet for a while, and Kirishima could feel himself starting to get drowsy as the sound of his boyfriend's soft breathing began to lull him to sleep. Bakugou reached down and pulled the blanket up to cover them both, and Eijirou let a contented smile cross his face as he was enveloped in warmth.

"Good night, Kat."

"Good night, Red."

And with that they both drifted off to an easy sleep, cradled comfortably in each other's arms.

Yes I know, lots of smut these past few chapters. Some will hate me, some will love me, but we will be having a break from it now. More fluff to come and...could it be...PLOT!? *le gasp*

Thanks for reading and putting up with my stupidity XD
