Kaminari and Ojiro had a purely platonic and sexual relationship. At the same time, while they secretly sleeping together in hotel rooms, love motels, and their rooms, they were dating Jirou and Hagakure respectively. Well, it was only a secret from the public, their girlfriends were well aware of the nature of their relationship. Kayama, however, didn't even try to understand class A's polyamorous bonds.

Even Todoroki was dating Yaoyorozu who was dating Jirou. Simultaneously, Midoriya was dating Uraraka who was also dating Asui. It was the main reason why so many of them hadn't figured out their potential marriages since they were unsure of how that would affect those relationships. Even the married pairs were in open relationships.

Kayama cleared her throat once the pair sat down. "So, what brings you two in here today?"

Unlike previous clients, Kaminari and Ojiro made the decision together to come there. They discussed it for quite some time but after seeing the practically magical after-sex glow on the faces of their friends that have gone to the clinic, they decided to give it a try. They weren't exactly having problems perse but the sex just wasn't as fun nowadays. They couldn't figure out why though so they needed a second opinion.

"We tried a couple of methods," said Ojiro, "to 'spice things up' but, I don't know, nothing really worked for us."

Kaminari nodded along, crossing his arms. "Izuku and Fumi said something about you giving them some helpful tips but they were too embarrassed to tell us anything." He pouted a little, leaning back into the couch. "They also said something about how their particular tips wouldn't help us anyway."

The therapist clicked her pen. They weren't exactly wrong. The former didn't know where the prostate was while the latter had never attempted giving a blowjob. Not the most helpful advice for a couple that, more than likely, knew about—and had already done—those things.

"Okay," said Kayama, "what have you tried?"

"A couple of things," Ojiro professed.

"Makkun's constantly wimping out on me though," Kaminari mumbled.

Apparently, they attempted to have sex in public a few times but didn't have the guts to go through with it. Ojiro was way too paranoid that they would get caught. Then there was that time they tried using whips and riding crops but Ojiro was not very receptive to the idea of pain. Regardless of whether or not he was the giver. Then they tried using toys but…

"They just didn't do anything for me," Ojiro sighed. "I'm sorry Denki."

Kayama tapped the end of her pen against her chin. "I see…"

"So what's your diagnosis doc?" asked Kaminari. "I personally think Makkun's just too vanilla."

"Hey!" Ojiro snapped. But then he sank right back into his seat as he found he couldn't exactly make a counterargument. He just wasn't too interested in things like pain or risk. "Look… it's not like we're in a romantic relationship," he sighed. "Maybe… it would be best if we just end things since you're not really having fun anymore."

"What?" Kaminari blinked. "Hold on, Makkun, I—."

"I got it!" Kayama shouted. "I'm a genius!"

Both men waited for her to share her epiphany with them but she was busy scribbling something down into her notepad. Once she finished with whatever she was writing, she spun around her chair to boot up her computer. They looked over her shoulder as she pulled up various shady sites and rapidly typed away at her keyboard, her fingers a blur.

"Um, what are you doing?" Ojiro broached.

Kayama turned back around. "Ojiro-kun, can I talk to you privately?"

They knew that this was typically how she operated but they didn't even know what she had in store for them. They barely gave her much to work with and whatever was showing up on the monitor wasn't very reassuring. But then again, whatever advice she had given their friends had ended up going well for each of them. So they figured they wouldn't be losing anything if they gave it a shot.

"Alright," Kaminari sighed. "I just hope this works."

"Don't worry," said Kayama. "I always make sure my clients are comfortable with what I suggest."

Ojiro's tail drooped over the side of the couch. "I'm not sure how much I trust that statement."

"Kaminari-kun, I'll probably call you in later too."

—X—

Ojiro had been asked a rather simple question once alone with the therapist. What was something he'd fantasized about doing with Hagakure but didn't have the courage to ask of her? He wasn't really able to come up with anything substantial so she changed it up a bit. Rather, it was about the porn he watched and what was the kind of thing he ended up going back to time and time again. His entire face was red as he answered her with a stammer.

He and Kaminari talked about their relationship after that. Even though it was purely sexual, they didn't want to break what they had going on at the moment. So they decided that if the next time they had sex wasn't enjoyable for both parties, then perhaps they should invest in other partners. But for now, they were willing to try other methods.

A few days later, a package arrived at Ojiro's house. He knew it was coming but he was still shocked that one could buy a doctor's exam table with wax paper so easily on the internet. He didn't have to call his lover to come over either. Kaminari was staying while Hagakure was away on a stealth mission.

"How expensive was all this?" Ojiro asked.

Kaminari shrugged. "I just gave her my credit card info."

"Won't Kyouka be mad at you for that?" he asked.

"Nah, she didn't want us to have a joint account."

"Honestly, that's a really smart move on her part."

While Ojiro set everything up in the cleared-out guest room, making it look like an actual medical office, Kaminari went to get changed in the bathroom. It was rather embarrassing for the tailed hero to admit that this was one of his fantasies. His cheeks took on a pinkish tint as he put on a blue patient gown and he thought about the idea of a sexy nurse 'taking care of' him.

The fact that it was going to be Kaminari was already getting him semi-hard.

As he sat down on the table, he wondered if the wax paper was going to be too noisy. He also didn't appreciate the draft he felt on his back. Or the fact that his heart was beating out of his chest. They'd fucked countless times over the years, why was this so different? Now that he thought about, there was no Kaminari yet. What was taking him so long?

"Uh," Ojiro uttered, "Den… K-Kaminari-sensei?"

A sultry voice called back. "The doctor will be right with you."

The door creaked on its hinges as it was pushed open. Ojiro wasn't sure what he was expecting. An open white coat, stethoscope hanging on a bare chest, and ill-fitting slacks perhaps. But instead, what entered was Kaminari with cute clips pinning his bangs back, a tight white nurse dress, go go boots to match, and fishnet stockings.

"Denki?!" Ojiro blanched.

"I hope I didn't keep you waiting," Kaminari smirked, his voice lilting and smooth.

The other blond sashayed across the floor towards Ojiro who was getting redder by the second. He was not prepared for this whatsoever but he couldn't escape the room. Not when a warm hand brushed up his thigh, sending excited shivers of his spine. There was a slight bulge in his pelvic region that he had no chance of hiding. But even more obvious was the way his tail was wagging enthusiastically.

"Um, well," Ojiro gulped. "N-No, you didn't keep me waiting…"

Kaminari giggled and winked. "That's good, don't want to upset my favorite patient~."

Ojiro was hyper aware of the fact that there was a hand caressing his inner thigh, disappearing up his gown and stopping just below his erection. He tried his best to control his breathing but he could hear his heart pounding in the back of his head. He didn't know if it was because he was really turned on by the skimpy outfit that Kaminari was in or the seductive tone or the friskiness that was the cause.

"So, I… haven't been feeling too well lately," said Ojiro, trying to keep his voice even.

Kaminari pouted and batted his eyelashes which Ojiro was just noticing were rather long. "Oh no, well we can't have that."

It was all of the above. It was definitely all of the above.

"I'm not sure what the problem is," Ojiro murmured, his eyes darting in every direction. He wanted to focus on anything other than the bouncing ass that Kaminari was showing off, barely confined in the skirt. But his eyes were always drawn back to the voluptuousness. "So I… was hoping to get an opinion from you."

"Well then," Kaminari giggled, "let's start the examination."

Kaminari was really getting into his role. He started by 'checking Ojiro's blood flow' with his stethoscope which was actually just his rubbing his hand all over his pecs. Of course he had to knead and pinch at his pink nipples. Next, he wanted to check Ojiro's temperature but 'forgot the thermometer' so instead he gave Ojiro a very deep kiss. His tongue dug its way deep into his mouth, exploring the insides with vigor. Ojiro was completely out of breath and red-faced when it was over.

"You do feel pretty warm," Kaminari remarked. "Especially down here."

Ojiro jolted when he felt slender fingers wrap around his balls, his dick twitching right above it. "Oh, uh, well…"

"Let's see if we can do something about this," said Kaminari.

He took the end of the gown and lifted it over the hard-on, like he was unveiling a special surprise. He licked his lips at the sight of the cock, standing straight up. He first tasted the tip, getting the droplets of oozing pre onto his tongue before wrapping his lips around it and sucking. He continued to push out his ass while bringing his hands around to grope Ojiro's, all while slurping on the cock down to its base.

Ojiro was familiar with his lover's deepthroat skills. And unlike with his girlfriend, he could actually watch since with her, it always looked like his dick would disappear. But with Kaminari, he had a perfect view of his pretty face slobbering the entire length of his dick. His toes curled and his tail wagged as he placed a hand on the back of Kaminari's head, fingers running through his long hair as he acted as though he was moving the head up and down his member.

The wax paper crinkled and rustled underneath from every slight movement. But they paid it no mind.

"Denki, fuck," Ojiro moaned.

Kaminari loved hearing that sound. Almost as much as he knew Ojiro loved hearing him gag whenever he swallowed his cock down to the base. He hitched up his skirt over his ass and Ojiro made another noise. Surprise for sure. He was showing off his black lacy panties and even though Ojiro couldn't see down below, he must've known that Kaminari was jerking off his own dick.

"You like what you see?" Kaminari teased.

Ojiro looked to his lover's face and noticed lace peeking out from underneath his low-cut collar. "Is that a matching bra?"

"All for you," Kaminari winked.

Ojiro wasn't quite sure what to think but his dick didn't. It felt like he had gotten even harder simply at the thought of Kaminari in nothing but sexy lingerie. The tip of the other man's cock sticking out from the waistband and his nipples poking out through the bra.

"I didn't think you could look better," Ojiro chuckled.

"Never underestimate me, Makkun," Kaminari grinned.

Ojiro watched as his lover unbuttoned his dress, showing off the lingerie and his body in all its glory. The muscles of his hero-toned body glistening beautifully. His chest and ass accentuated by the extremely revealing undergarments.

Kaminari returned to sucking off his lover. He started by putting one of Ojiro's balls into his mouth and let his teeth gently run over the skin as he licked, getting the sweat onto his tongue. He did the same to the other before returning to the actual shaft. He liked rubbing his face across the length, feeling the heat coming off it. He maintained eye contact with Ojiro while running his tongue across the cock.

Ojiro was panting hard as he watched his partner close his mouth around the mushroom tip. He tugged at his hair slightly and when he felt himself getting close, he couldn't help forcing Kaminari's head down. He shot his load straight down Kaminari's throat as he arched his back, trying to push himself as deeply into him as possible.

"Fuck, Denki," Ojiro grunted. "Sorry…"

Kaminari pulled away once he was free, mouth still open wide as some of the cum pooled on his tongue. He didn't swallow it yet. Instead, he climbed up onto the table, pushing Ojiro down as he grinded up against him and pressing their mouths together. He swirled the cum in his mouth, sharing it with the tailed hero and almost instantly, his cock became hard again.

"You didn't think you were finished, did you?" Kaminari smirked.

Ojiro could see a cum-string still connecting their lips. "Uh… well…"

Kaminari went back over to a drawer and got a strange contraption out which he set at the foot of the table. He instructed Ojiro to lay back and keep his tail hanging off the end, still using that sweet but sexy nurse voice of his. He then took Ojiro's legs and set them in the holds, spreading them wide so that he could get a good view of the blond's hole.

"Your check up isn't done yet," Ojiro grinned. "We still need to give you your shot."

Ojiro gulped as he tried to control his wagging tail. "O-Okay."

Kaminari positioned himself and pressed his face into Ojiro's ass, getting a good lick of the hole. He heard a moan as he continued to bury his tongue as deeply as he could and play with the insides. He couldn't exactly go very deep but he knew just what to do to get Ojiro writhing in pleasure as he acted as though he was devouring his lover.

"Feeling better than when you came in?" Kaminari winked.

Ojiro was having a hard time concentrating. He almost forgot that they were doing something special to begin with. "Uh, well, yeah…" He felt like he was making Kaminari do all the work though so he had to return the dirty talk somehow. "Well, I want you to make me feel even better, nurse. That injection you mentioned, I want it in me."

"Well, we have a rather impatient patient," said Kaminari.

Ojiro was rather flexible so he didn't really need the device to keep his legs spread. They got rid of it as he grabbed the underside of his knees and pulled them as high as he could. Meanwhile, Kaminari got the lube and slathered it onto his fingers before rubbing it onto the entrance.

He slipped off the stockings and pulled the panties down so that they were right below the balls. He then rolled on a condom quickly before bringing his attention back to Ojiro's hole which was twitching sporadically. Without wasting anymore time, Kaminari penetrated him, his cock throbbing as it found itself in the familiar cavern.

Kaminari climbed onto the table itself and Ojiro, without thinking, wrapped his legs around his waist and threw his arms around his neck, pulling their bodies together. Not that Kaminari had any issues with that. It just meant they got make out some more as he pumped his body up and down, in and out of his lover.

The table wobbled and the wax paper crumpled but they only cared about fucking. Ojiro liked feeling the smooth skin underneath his palms and playing the strap of the bra. He wanted to feel the lace against his own chest though so he reached between them and managed to tear off the gown, grateful that it was just cheap fabric.

"You're quite—hah~—the professional at this, nurse," Ojiro panted. "Do you do this with all your patients?"

Kaminari smiled before going down to suck on Ojiro's nipple, his hips on autopilot now. "Only the cute ones."

Their breath in their faces was hot. Ojiro's tail was wagging non-stop but he had the willpower to curl it up and grind the muscular part against Kaminari's ass crack. He knew for a fact that it would really get him going and he was right. Kaminari let out a lustful groan before kicking it into overdriving, thrusting faster and going deeper.

"Oh, fuck, mmh, fuck me Denki," Ojiro moaned.

Kaminari could faintly hear the table rhythmically creaking under their weight. "God, Makkun, you're so tight."

Ojiro was finding it difficult to think. All he wanted was to hold on and enjoy the ride. Kaminari wasn't exceptionally big or wide, but he knew how to work Ojiro's body. What parts of him were most sensitive and which parts were most receptive to his touch. They'd been together long enough to know these things.

Finally, Kaminari reached his climax and they were both breathing raggedly as they laid there. Suddenly, they were aware of the annoying wax paper underneath but what could they do about it at that point? They just wanted to lay on the table. Kaminari, on top of Ojiro, was unable to move anywhere else since he didn't want to just fall onto the floor.

"We don't have to do this every time," Ojiro muttered, "will we?"

Kaminari pushed himself up so that they were face to face. "I don't know."

They had talked about it for a while, that they didn't want to break what they had. There had been times when they wondered if they should become romantically involved. But unlike their other friends, they didn't know how to manage a polyamorous relationship. It seemed complicated even when the others promised it wasn't.

They could still remember when their fuck buddy relationship started. The tuft at the end of Ojiro's tail was always sensitive and he always felt a little aroused when touched there. Kaminari, having sat behind him, was constantly playing around with it. Then one day, Ojiro arrived at the electric hero's house drunk and unannounced, telling him to take responsibility.

They didn't fuck that night. But they did eventually.

"Well… what do you know?" Ojiro asked.

"That I like what we have," said Kaminari. "That I like you."

"Do you… want to try going out?"

"I think it's worth a shot."

They had to share this development with their girlfriends and the rest of their former classmates. Not to mention go on their first official date together. They still weren't sure if this relationship would even last very long. But they didn't have to think about the future for the moment. For now, they just wanted to seal the deal with a kiss.

—X—

A few days passed and Ojiro was out with Hagakure at a cat cafe. They were discussing their plans for a double date with Kaminari and Jirou when he got a call from said man. Thinking it was a convenient coincidence, he put it on speaker so they could all join in. However, the shout that burst through the device had him fumbling to turn it off.

"Why does Kyouka have a picture of me?!"

Ojiro couldn't understand the problem. "Wha? What do you mean?"

"That nurse outfit!" Kaminari snapped. "She has a pic of that!"

The cats hissed as they took off from the loud noise. Other patrons were either pretending not to notice or they were giving the pair dirty looks. A manager came out of the kitchen, looking ready to kick them out. Hagakure, on the other hand, burst into raucous laughter and was having trouble trying to calm down enough to argue with the waiter asking them leave.

Ojiro stepped outside and brought the phone to his ear. "What are you talking about?" he whispered.

"Hagakure was in the room, wasn't she?" Kaminari barked. "She sent that pic to Kyouka!"

The tailed hero looked over to his girlfriend who was still trying, and failing, to stifle her cackling. He let out a groan as he tried to formulate a response. "Look, Dr. Kayama said that it might be more… fun for me if I knew someone was watching. And… Tooru always said she wanted watch."

"You said she was on a stealth mission!"

"Watching us was that mission."

"That it, I'm breaking up with you!"

"What, Denki, wait!"
