Chapter Text
It was a bright and early Saturday morning in Japan, the birds were singing beautifully outside and bringing a smile to anyone awake at such an hour. Izuku Midoriya was one such person, the UA student was happily whistling a tune as he got dressed and packed his bag, a full day of training ahead of him.
“I'm not sure how long I'll be, I'm training with Kacchan, Kirishima, and Tetsutetsu and you know they'll be begging me to stay for as long as possible. If anyone needs anything just text me and I'll grab it before I come back,” he said while opening the door before suddenly remembering something. He turned back to the room and blew a kiss into the darkness. “I love you girls! I'll see you later!” he exclaimed cheerfully before closing the door shut.
Seconds passed, then minutes, the room stayed deathly silent until a sudden groan echoed throughout the room. A hand reached out and grabbed onto the top of the bed, and soon Itsuka Kendo was dragging herself up from the ground. She was completely naked, with white dried particles littering her chest and the bottom half of her body.
“Anyone else still alive?” she asked around, causing a collection of groans to echo off the walls.
“Just barely. Fuck, everything hurts,” Kyoka Jiro groaned from her sport on the floor, the arms of Momo Yaoyorozu wrapped securely around her. Like their red-headed friend, the two of them were also naked with dried white particles over a large percentage of their bodies.
“Girls meeting in 20 minutes? Ya know, after everyone showers first?” Itsuka suggested, staring at the sea of bodies filling every part of Izuku's room, from his bed to the floor to his closet. Instead of actual answers, she received even more groans, which she assumed meant everyone agreed with her idea. “Great… actually maybe make that 40 minutes. I-I need to lay back down,” she said before slumping back into the ground.
(One hour later)
It took much longer than originally intended to get everyone up and moving, with some of the girls needing to be woken up while a few others actually had to be carried to the showers. After showering and getting dressed, the girls of 2A and 2B were finally settled in the common room of the 2A dorm building. Many of them were awake while a handful of others tried their best to keep their eyes open, still exhausted from the events of last night. Thankfully as Kendo cleared her throat, all attention immediately snapped towards her direction.
“With everyone here and awake, I think we can finally get this meeting started,” she announced to everyone present. “First let me start by reiterating that we all love Izuku, we aren’t here to discuss breaking up with him or asking him to change or anything like that, understand?” she asked the crowd, receiving nods of understanding and agreement in return. “Good, now with that being said… we need to figure out what to do regarding his sex drive.”
Some of the girls blushed at her phrasing, still awkward around such talks and acts despite being with the boy in question for so long and having many, many nights filled with passion. Others began muttering amongst themselves, trying to workshop a plan to deal with their situation. When they all got together and originally came up with the plan of entering a polyamorous relationship with Izuku, none of them could’ve expected him to be a literal demon when it came to the bedroom. He was like the final boss in a video game, but despite how much you leveled up or how strong the equipment you found, he just continued pummeling you to the ground.
It’s not like they hated having sex with him, by far it was the complete opposite in fact. Even those who were once considered prudes (mainly Ibara) had fallen victim to the sensational addiction which was lust for the one they loved and adored most in the entire world. But while they couldn’t get enough of it or him, sometimes it got to be just a little bit much.
“May I suggest some of you picking up a little slack? I can’t be the only one consistently going four rounds with the guy!” Mina exclaimed from her spot alone in a recliner chair. Again certain members of the group blushed bright red in embarrassment, remembering the state Mina was usually left in after Izuku was finished with her.
“Now now, it’s not fair to cast blame or make others feel bad, Mina,” Momo, the mother of 2A, reprimanded her close friend for her hurtful words. “Some of us here aren’t built for lasting long, we’ve known that for a while now. It isn’t right wanting them to go ‘Plus Ultra’ when their bodies can’t handle it,” she said, causing the pink-skinned girl to sigh.
“Sorry girls, I’m just sore and tired is all. Isn’t a good excuse for my bitchiness though,” she chuckled, with many accepting her apology. “Maybe we should speak to a professional about this? Like, I don’t know, a sex professional?”
“Hmm, not a bad idea. We all do know one, and she’s close by…” Kendo trailed off, with the girls nodding to one another. “Does anybody know Ms. Midnight’s office hours?”
(Midnight’s Office)
With it being a Saturday, Midnight had expected it to be like almost every other Saturday that she worked, long and boring. There was never really anything to do, all her assignments had been graded and obviously, there were no classes to teach. The only excitement she ever got was if there was a fight in one of the dorms, and usually, Aizawa was always quick to take care of it. Something about not trusting her with a room full of young adults high on adrenaline, or something silly like that.
That being said, imagine the R-18 hero’s surprise when a knock came to her door, and suddenly her office was filled with 13 girls from classes 2A and 2B, and Mei Hatsume from the Support Course.
“Hello there girls, what can I do for you today?” she asked with a happy smile, grateful they were here to alleviate her boredom.
“Ms. Midnight, we were hoping to get some advice from you. Regarding a… very personal matter that we all share,” Uraraka said with a blush, earning a raised eyebrow in return.
“It depends on what this ‘personal matter' is regarding. Mind being a bit more specific?”
“Well, Ms. Midnight… as you undoubtedly already know, we've all been dating Izuku Midoriya for a while now,” Yaoyorozu began, causing Midnight to give a nearly predatory smile. Of course, she knew, Midnight was the one who first spoke to the girls and gave them the idea of a polyamorous relationship.
“I'm pretty sure almost everyone in Japan knows that by now, but please, continue,” she teased, causing some to blush.
“And while we love him dearly, he's becoming a bit… much to handle.”
“In what sense?”
“He won't stop with all this sex,” Mina put in bluntly, causing many to blush from how awkward it sounded coming out loud. The girl suddenly yelped as something stabbed her, and she turned to glare at Jiro. “What was that for!”
“Don't phrase it like that, dummy! You're making Green sound like he's a horrible person!”
“Is Midoriya forcing sex on you girls?” Midnight asked seriously, more than happy to get the boy expelled if that was the case. She took the allegation very seriously and would make sure anyone would be thoroughly punished, even someone as seemingly sweet as Midoriya.
“No! No no no, nothing like that at all!” Toru exclaimed, the other agreeing with her.
“When we first got with Izuku, we didn't expect him to be so... youthful,” Yaoyorozu tried to explain in a PG way that Midnight would hopefully understand.
“Yeah, he's very youthful. He's always shooting his youthfulness all over us.” Mina snickered, earning herself another stab from Jiro.
“Oh! Oh, I understand now. Midoriya has a very high sex drive and none of you can keep up,” Midnight said it with such ease, and earned plenty of blushes from the group. “Have you tried just being honest with him? Explain that you love him and the sex but sometimes need a break?”
“We've considered it. But, well, the thing is…”
“We feel like we owe it to him,” Uraraka continued from where Yaoyorozu left off. “He's done so much for us, so much for this country ! It might sound a bit silly but, I guess we just want to return the favor for everything he's done. I mean, he helped get my parents so many construction contracts after the war! We've always struggled but now, money isn't an issue anymore.”
“He's always helping me babysit my siblings, and often does it himself so I can get a break and have some me time,” Tsu chimed in.
“He's always helping me in the lab! So many of my babies have been perfected and haven't exploded thanks to him!”
“He's been helping me with my Japanese!”
“I would've failed most of my classes if it wasn't for him helping me buckle down and study.”
“Not to mention he's always the first one to take care of us when we get sick.”
Midnight nodded along as the group broke out into various mutters, listening to each of the ways Midoriya has helped them throughout the time that they've known him. While their way of thinking was a bit silly, it was indeed sweet and she could see where they were coming from. It was no secret Midoriya had a hard life even before entering UA, hell, she and the other teachers knew what he went through before receiving One For All; the universe definitely fucked the young man over constantly.
“Alright, alright, I understand your points,” Midnight spoke up, causing the group to quiet down. “Well if talking to him isn't an issue, and given how your relationship with him works, have you considered bringing in more girls to help… satiate his sexual appetite? Maybe a girl who can keep up with him?”
The twinkle in her eyes was a dead giveaway of what the older hero was getting at. Glances were exchanged between the girlfriends, silent conversations were being had in real-time as the girls knew each other that well. The idea wasn't awful, they knew Izuku had a crush on the R-18 hero so it probably wouldn't take much convincing for him to accept having a night with her. That being said, did she know what she was getting herself into?
“Are you sure Ms. Midnight? You haven't seen Izuku in action before. With all due respect, I think you may be a bit in over your head with this.”
“Honey, I'm the R-18 hero for a reason . I've drained more men dry in my life than someone with a vampire quirk,” she said with bravado and confidence. “Get me a time and place and I guarantee you, he'll be no match for me.”
“How about tonight in his dorm room?” Setsuna suggested, causing Midnight to smile wickedly.
“Consider it done.”
(Later that evening)
“I’m sorry for taking so long,” Izuku announced as he opened the door to his room, a towel draped over his head as he tried off his hair. “Kirishima and Tetsutetsu started getting competitive, which made Kacchan start getting competitive, and he wouldn’t let me leave until he beat me in something… he passed out from exhaustion after trying and failing so many times.” He chuckled while closing the door.
“You poor thing, sounds like you need some stress relief ,” a voice he wasn’t expecting spoke, causing the boy to jump in fright and turn around, pulling the towel off his head and staring with wide eyes as his teacher Midnight sat on the edge of his bed with one leg crossed over the other.
“M-Ms. Midnight! W-What are you doing here?”
“A few little birdies told me you’ve been working yourself so hard lately, and how they wanted to reward you for being such a good boy ,” she said in a sultry tone, smirking as she watched him shiver in delight. “So how about it, Japan’s savior? Think you can keep up with an old pro like me?”
Izuku blushed a dark shade of crimson as he tried and failed to speak, his brain unable to comprehend just what exactly was happening. His phone violently bussing snapped him out of his trance as he quickly checked it, finding numerous messages from his girlfriends encouraging him to go for it and to have fun. They must’ve been watching him from somewhere as he entered his room, or perhaps Kyoka was listening in on the conversation and relaying it back to the girls. He gulped, hands slightly shaking as he texted a quick thank you to the group chat. If the girls wanted to reward him, who was he to deny such a generous gift?
“Well Midoriya? What do you say?”
“...Are you on the pill?”
