            Bakugou was the first to wake up this time. When he slowly opened his eyes and glanced around, he saw Kirishima on the opposite side of the bed with both pillows and most of the blanket. He was snoring softly in his sleep, his chest rising and falling ever-so-slowly with every breath. The redhead looked weirdly adorable like that, Bakugou couldn't help thinking as a warm smile began to play at his lips.

He shook his head to clear it as he pulled himself out of bed, wincing as he felt the skin of his back stretch and felt a dull pain spread through his body. He had forgotten all about the scratches on his back and, no doubt, his careless movements would have reopened some of the scabs that had only just grown over the wounds. It didn't hurt very much and that wasn't what bothered him, it was the fact that it just felt weird, and he didn't have any better word to describe it.

With a sigh he finished getting out of his bed and went to pick out some clothes. He grabbed some darker pants and then decided on a black shirt so that if he did have open cuts, at least he wouldn't leave any blood stains on his shirt. He made sure to keep quiet as he got dressed so he didn't wake his boyfriend, then left the room and took extra care to close the door silently before making his way downstairs to make breakfast.

After a bit he heard a yawn and turned around to see Kirishima walking into the room with an easy smile on his face. He was wearing a pair of jeans and a plain white tank top that did absolutely nothing to hide his neck. The newest hickey from last night was only just starting to turn a faded purple color, but the older one was dark black and stood out on his soft light skin like beacon.

"Morning," Kirishima said sleepily, though he still had that pleasant smile on his face and a shining look in his eyes.

"You sure you don't want a sweatshirt today?" Bakugou asked with a note of worry in his tone.

Kirishima frowned and looked down at his shirt. When he didn't seem to understand Bakugou rolled his eyes and tapped a finger on his own neck where one of the bruises was on Eijirou's. The other boy's eyes widened in recognition and he made an 'O' with his mouth before wheeling around and bolting out of the room.

Bakugou just laughed as he returned to making the food. When Kirishima came back a minute later he was wearing a black sweatshirt that looked a tiny bit too big on him and he plopped himself down at one of the tables. After a minute Bakugou walked over with two plates of food and set one down in front of him before sitting down on the opposite side of the table. He sniffed the air and frowned.

"Are you wearing my cologne?" Bakugou asked confusedly as he recognized the smell of coffee.

Kirishima spoke through a mouthful of food, "Your sweatshirt smells like a caramel latte!"

Bakugou's eyes narrowed. "Dammit Spikey Hair did you really go into my room and grab my sweatshirt!?"

There was a long pause before he answered quietly, "...It smells like a caramel latte."

Bakugou rolled his eyes in annoyance but ended up laughing despite himself. Then he groaned as the realization struck him, "We've graduated to 'wearing your boyfriend's sweatshirt' phase of our relationship!"

The redheaded idiot grinned in response.

After that they lapsed into an easy silence as they ate, both smiling cheerily in each other's company. When they were done Bakugou got up to wash the dishes and got lost in thought as he tried to decide on what to do for the day. But it seemed like it would be a rather lazy day, he decided.

"Ay, Kat?" Kirishima asked as he walked up next to him.

"Hm?"

Kirishima shrugged as he asked, "Do you wanna spend the day together?"

"I guess," Bakugou answered. "What did you have in mind?"

"Maybe we could go to the pool?" Kirishima suggested. "Mr. Aizawa said we can use it over the weekend as long as it's for exercise...technically."

Bakugou huffed quietly with laughter as he said skeptically, "Oh, yeah, the two of us half naked in a public place. I can't see anything going wrong there."

Kirishima frowned. "You know Mr. Aizawa won't check the pool until it closes anyway, and all of our classmates that stayed for the weekend are going to be hanging out again today. It'll be a good test to see if we can control ourselves, like you wanted to know."

Bakugou grumbled, "Fine, but we better not get caught."

"Alright, I'll see you there!" Kirishima said happily.

"Yeah, whatever," Bakugou said back.

Kirishima gave him a big smile and an even bigger hug before he bounced out of the room with a cheery jump in his step. When Bakugou was finished washing the dishes he grabbed his swim trunks and started walking out to the pool. The thought of being found out by someone who saw Kirishima's hickeys or the scratches on his back was a terrifying idea, but at the same time the thought of spending some time in the pool sounded like a great way to relax.

The cool water on his skin and the promise of a nice and convenient way to workout made for an appealing combination. Throw in a shirtless Kirishima...well, maybe it was best not to think about that. He had said that he wanted their relationship to be based on something besides lust. Kirishima didn't seem to take it that seriously, and no doubt he cared a lot more about him than just for sex, but Bakugou hadn't made the rule for him. He was trying to put a rule in place for himself, and the idiot wasn't making it that easy.

Bakugou was terrified at the possibility that he only liked Kirishima for the sex. But, more importantly, he was terrified of what would happen if he lost control of himself around him. He didn't understand his own body most of the time, and his attraction to his boyfriend was no exception. Over and over he told himself that he cared about Kirishima for a number of reasons, he was certain of it, but when he was blinded by lust it was impossible to remember that. He didn't want that to consume him.

When Bakugou got to the locker room outside the pool he was buried deeply in his troubled thoughts. In the distance he heard faintly the sound of splashing and guessed that Kirishima was already there but didn't think anything else of it. Mindlessly he changed into his swim trunks, and as a quick thought decided to check his back in the mirror. He twisted his neck around and pulled at his shoulder to get a good look. Deep, bright red marks lined most of his back and his shoulders. They were massive, dark, obvious, and completely impossible to miss, of course. Hopefully Kirishima was right about no one seeing them....

He tucked his clothes into a locker and reluctantly stepped outside, part of him being convinced that with his luck half their class would be waiting there for him in shocked silence. But instead he saw only Kirishima, floating in the pool on his back with his eyes closed as he drifted peacefully across the top. When he sensed Bakugou coming he opened his eyes to look up at him and smiled.

"You wanna see somethin' kinda funny?" Kirishima asked.

Before Bakugou really had a chance to answer, Kirishima hardened his entire body and sank rapidly to the bottom of the pool. He sank like, well, a rock. When he popped back up he was grinning like he was proud of his cool trick and Bakugou rolled his eyes in annoyance, though he smiled a little internally.

"You idiot," he chuckled.

Kirishima's smiled only widened at that. "Well, are you coming in or not?"

"Race you to the other side?" Bakugou suggested.

Kirishima smirked as he yelled, "Alright, but you can't just use your quirk to fly over the pool like last time, okay? Go!"

He was already in the middle of the pool, so he was convinced that he would easily win with his head-start. But Bakugou grinned evilly as he bolted forward and with one massive explosion shot himself into the water like a torpedo. It wasn't as fast as in the race their whole class had had before, but he was still at the other side within seconds. He collided roughly with the opposite wall just ahead of Eijirou.

"No fair!" Kirishima pouted, though there was a humored gleam in his eye.

"You said I couldn't use my quirk to fly over the pool, not that I couldn't use it at all," Bakugou pointed out slyly. "What are you gonna do about it, Shitty Hair?"

At once Kirishima reached up and planted a kiss on Bakugou's lips, taking him by surprise. Even more surprising was the light blush that rose on Bakugou's cheeks from the unexpected kiss, but he was good at hiding it behind his childish scowl. He glared at him for a minute until Kirishima started laughing at his angry expression, and that sound was just enough to melt his icy cold exterior.

"How's your back?" Kirishima asked when his laughter died down somewhat.

Bakugou turned to the wall and pulled himself up a bit as he answered, "See for yourself."

"Ouch," Kirishima said at once as he saw the scratches in good lighting for the first time.

Kirishima raised a hand out of the water and traced his fingers along four of the lines, feeling somewhat humored by the fact that they fit perfectly. Of course they would, but it was still interesting to trace his fingers along the scratches so flawlessly.

The touch sent shivers all along Bakugou's spine and throughout his body, and when Kirishima saw that he liked it he moved his hands to either side of him and pressed his lips to the marks instead, placing soft open-mouthed kisses all over the lines. Bakugou let out a long sigh and lowered his head onto his arms as he basked in the feeling of his soft lips around his sore back.

"Look at my handiwork," Kirishima said warmly over Bakugou's shoulder as his lips reached the end of the last set of scratches. His hands were on either side of him now, their bodies just barely brushing as the shifting water made them sway the slightest bit, sometimes against each other.

"When did you get to be the big spoon?" Bakugou commented when he noticed how close they were.

Kirishima chuckled a bit and pressed against his boyfriend as he answered, "I dunno, but I am now."

"That's not fair."

"Why not?" Kirishima asked defensively.

Bakugou answered, "Because I'm taller-"

"By two centimeters."

"Well I'm six months older, and you're usually the submissive one anyway."

"Ooh, daddy!" Kirishima laughed, then went silent.

Bakugou was so taken aback by the comment that he froze and felt heat rise to his own cheeks. It took him a moment to fully comprehend what he had heard, and when he did he slowly turned around to raise an eyebrow at Eijirou. The poor boy was blushing possibly more than he ever had before with an absolutely horrified expression on his face.

"That is not what I meant at all," Kirishima tried to explain through his nervous laughter. "I was just kidding, man. Like I would never really say that-"

Bakugou turned around completely to face him and interrupted him with a firm kiss, effectively shutting him up before he could mutter for too long. When he pulled away he said, "You don't have to be so nervous around me, you idiot. Like it or not I think you're stuck with me now."

"Damn it," Kirishima teased as he let out a deep sigh of relief.

"But while we're on the topic," Bakugou began casually, "Do you have any kinks I should no about?" He prayed that his calm demeanor would effectively hide just how curious he was about the topic.

Kirishima wasn't sure how to respond to that, so he just mumbled shyly, "Are we really talking about this?"

Bakugou smiled innocently. "I won't judge. Maybe there are even a few we could try sometime..." He licked his lips slowly, mostly as a joke at first but it seemed to have a very real effect on his boyfriend.

"Well I don't know," Kirishima groaned with his face still bright red. "I honestly haven't given it that much thought. I haven't...seriously considered anything.

His emphasis on the word 'seriously' gave Bakugou doubts, and he persisted, "There has to be something you've thought of. Maybe just something simple that turns you on, or something you might be willing to try?"

"If you're so confident about it why don't you go first, tough guy," Kirishima countered.

"Alright," Bakugou said confidently, though he was freaking out quite a bit on the inside as he tried to think of something. "Well, I really liked whispering dirty things in your ear during that game of truth or dare. We should do that more."

"No fair that's an easy one," Kirishima protested. "That shouldn't even count."

Bakugou chuckled, "Nope, it counts. You can tell me anything that turns you on, or anything that you might like to try, and I promise I won't judge you for it."

"Promise?" Kirishima asked, to which Bakugou nodded. With a deep breath Kirishima slowly mumbled, "...Spanking?"

"That could be arranged," Bakugou said much too calmly with a big smirk on his face, which made the redhead both relieved and a little more self-conscious at the same time somehow. "I guess that means I have to go again. What about bondage?"

Kirishima gave a nervous laugh, though after a brief thought he decided he wasn't entirely opposed to trying it, if his boyfriend really wanted to. "We could try it, I guess. I don't know what else to say, man. What about...like...oral?"

The last word came out as only a whisper, making Bakugou think that it was something he really had thought about before but never would have brought up without the constant pestering. This was good, it meant they were getting somewhere in their conversation. Some distant part of him was saying he should stop and stick to his rules in public, but something about the scene put him in a flirty mood and he couldn't seem to help himself.

Kirishima felt like his brain wouldn't stop screaming at him to stop. He had said too much, though it seemed the other boy wasn't surprised or daunted in the slightest at the suggestion. Some part of him was curious about different things they could try, but he was still more than happy enough with just Bakugou for now. Just the thought of sleeping with him again was arousing enough without thoughts of spicing things up. But he had to admit, the conversation was very alluring as well. Then again, maybe Bakugou was right originally and that was the last thing they needed to have on their minds in that moment.

"That's not entirely out of the question," Bakugou said after he thought it over. "For me I guess...why not some shitty roleplay or something?"

"That's pretty general though, is there anything specific you had in mind?" Kirishima asked.

Bakugou shrugged. "That can be up to you, it was just an idea. If I had to pick something...oh I don't know, like a servant-master relationship?"

"You're very dominance-focused, aren't you?" Kirishima pointed out with a laugh.

"Sue me," Bakugou answered. "But I don't have to be the dominant one every time, if you want."

"Really?"

"Really."

Kirishima smiled as he responded, "Well I don't mind being the submissive one with you anyway."

Bakugou smiled back and kissed him softly, closing his eyes as he focused on the feeling of their lips brushing. Not for the first time he couldn't believe that he deserved to be with such a man. Someone so amazing, kind-hearted, handsome, tough, and selfless as Kirishima could do so much better than him, and he was certain of it. But he didn't want to think that, not now. He shoved his doubts away to the very back of his mind as he kissed him.

When he pulled back and opened his eyes, he felt a little smirk play at his lips and said, "Well anyway, I think we have more than enough ideas for this weekend to try."

"So, you want to try all these...next weekend?" Kirishima said nervously.

Bakugou immediately tried to reassure him, "Only if you want to. We don't have to do anything at all if you don't feel like it."

Kirishima shrugged. "Well, we could try some things."

"You're impossible," Bakugou said as he rolled his eyes and pushed him away.

The other boy beamed at him in response and they eventually started to just swim around together as they had planned. They swam laps to get some exercise in and relaxed. Bakugou especially loved the feeling of the cool water on his skin, the feeling of the silky-smooth surface shudder under his touch. But he would never in a million years admit that he was actually enjoying doing something relaxing.

They agreed to have another race, this time without quirks entirely. Still Bakugou tore through the water effortlessly and arrived at the other side first, though Kirishima was very close behind this time. Eijirou would never cease to be awed at how amazing Bakugou was. He had such a perfect figure, and a certain grace with everything he did. Even his messy and violent quirk he controlled with careful, calculated movements.

He couldn't help but stare at him as they propped their elbows up over the side of the pool and tried to catch their breath. The soft light hair that covered his head was now plastered to his neck and forehead, weighted down by all the water in his hair as streams of it trickled down his back and along the perfect features of his face. Some of the droplets rested on his quivering lips while other dripped past his open mouth as he took deep breaths to settle his heartbeat and relax his body. His beautiful, perfect, gleaming body.

"Hey! What are you guys doing here?" Kaminari's voice called out from behind them.
