Nesting

Summary:

Denki has a tiring day, and all he wants is to fix his nest and cuddle with his boyfriend. And he may or may not be going into pre-heat.

I legitimately just wanted a fluffy fic of omega Denki nesting and cuddling with alpha Shinso, but I could only find one. Good thing I am a writer

Notes:

Hi! This is Scorpio748, this is my first work in the MHA universe. I love MHA and do plan on making more in this fandom, but don't know when. I do want to say thank you for reading this though, it means a lot to me! And I am sorry, the first part got away from me. I got way too into it and it ended up being longer than I thought. But it built up to the nesting which is what I wanted in the first place. Please enjoy!

A little about my omegaverse. Betas are the most common, then Alphas, then Omegas. Male omegas are not common, but are not necessarily rare either. Omegas will go into Pre-Heat about two days before their actual heat, and it just makes them tired, clingy, and heightens their instincts. They remain cognitive up until the first wave of their heat. An older alpha or omega can judge about when the full heat will hit. If there are any more questions I would be happy to answer them in the comments :)

(See the end of the work for more notes.)

Work Text:

It was a Friday. This meant that Mr. Aizawa was going to go harder on the class than usual. Most people know this already, but Mr. Aizawa is not a normal teacher. He tended to go harder on the class on Fridays so that they would have just that little bit more training before the weekend. 

So while the other UA classes loved Fridays because it meant that they could go a little easier on the schoolwork and not have to worry about homework, this was not true for class 2A. They were pushed beyond their limits, over and over and over again. Plus Ultra and all that.

While most Fridays were harsh, Denki Kaminari was having an especially rough time with this one. He could feel an itch building under his skin. He was exhausted, and not his usual energetic self. He also had the strong urge to go back to his dorm room, gather all of his blankets and pillows, and just sleep for a long time.

Of course he knew what this meant. He was going into pre-heat. However, since it was just pre-heat he did not get to get out of class. Mr. Aizawa was a little bit softer on him than the rest of the class, but just marginally. The older omega knowing the limits to a strong boy in pre-heat. He gauged Kaminari had about a day before his full heat hit.

He was just thinking this when Dark Shadow hit him, right in the chest. He had the breath knocked right out of him. “Good job Dark Shadow, now dodge his next attack.”

Kaminari had just righted himself and positioned his arm to shoot some of his lightning, but faked. He pretended to go right, and Dark Shadow followed. Kaminari was then able to shoot his aiming device to Tokoyami’s left with him barely noticing.

They continued to dodge eachother. But Kaminari was in control. He was able to maneuver so that he was in a straight line with his device. And once he was, he fired, “50,000 Volts!” His aim was true. Dark Shadow dodged the electricity due to his fear of light, and it passed right through Tokoyami. Stunning him.

With that, the exercise was done, and Kaminari collapsed to his knees. He didn’t go anywhere near his limit, but because of his pre-heat he felt like he was in the midst of an anxiety attack. With his instincts all over the place, he almost was.

Then he felt strong arms around him, and a comforting scent of lavender and coffee. His boyfriend, Hitoshi Shinso, was behind him. He leaned into him, head on his shoulder, nuzzling his neck.

He was so tired, but still had the other matches to watch before he could go back to the dorms. He got up, with some help from Shinso and went to revive Tokoyami.

It only took a small shock to wake the emo boy, but once he was they went to Aizawa to get their results. The viewing room was dark so that all of the monitors could be seen. Some kids were at the metal bars that were in front of the monitors, while some loitered around the back mingling.

Tokoyami, Kaminari, and Shinso all walked in and went for Mr. Aizawa. The man was standing next to Recovery Girl watching the monitors with Todoroki, Midorya, Tsu, and Ururaka. He turned around to face the students, black hair slightly waving as he moved.

“Tokoyami, while you and Dark Shadow have good communication you still need to work on your bond. Your objective for this semester is to have Dark Shadow be able to judge what you want him to do, without you saying it out loud. This will give you the element of surprise when you attack. Otherwise good job.” Tokoyami nodded at his teacher, letting his words soak in.

“Kaminari, you were out of it for most of the fight. If it were not for you having built up your reflexes over the past year and training with your support items you would probably not have been able to pull that off. That being said, you have also gotten a lot better at controlling your quirk. However, you can still improve.” He pauses, considering the student in front of him. “I am going to chalk your inability to focus today up to your ADHD and you being in Preheat. Now go sit down and watch the rest of the class. Shinso, you will be fighting next so that you can stay with him afterwards.”

Kaminari turned to his boyfriend, pecking his cheek before turning to go sit down with Mina and Sero. They were discussing his fight as he walked up. Mina was the first to jump up, “You did great hun!” She hugged him softly, not wanting to irritate him too much.

The previous year the three of them plus Bakugo and Kirishima had built a pack bond. They were the only ones besides Shinso who were allowed to hug him when he was in pre-heat. Anyone else who tried he would end up hissing at, and probably shocking.

He let her sit him down in between her and Sero. They watched as Shinso and Aoyama walked outside, and became visible on the monitors. They had never fought each other so this was going to be interesting.

The automated voice came on “One, two, three, START!” With that Shinso activated his capture weapon, and Aoyama his naval-lazer. They both dodged, Shinso using a beam to go high, and Aoyama going into a weird split to avoid a kick coming his way.

From his position on the ground Aoyama tries to take aim again. Aiming high and wide, trying to cover a bigger expanse. However, when he looked again Shinso was gone. At this point he had already shot his lazer, and was almost at his limit. He cursed his body again for not being able to handle his quirk.

“And times up!” the automated voice announced. Everyone else in the room was confused. Their timer said that the pair still  had 5 minutes left. Of course, Midorya was the one to figure it out. “It’s Shinso, he is trying to trick Aoyama!”

And that is exactly what happened, “What? But that felt way too … “ He was cut off, his eyes going wide and white as Shinso’s brainwashing took effect. Since there were no boundaries for him to walk out of bounds, Shinso had to either knock him out, or wait for the remaining time to pass.

Not knowing how much time was left, and not knowing if he could use his quirk for an extended period of time Shinso decided on the first option. He used his capture weapon, making sure that if he woke up by accident he wouldn’t be able to move. Once he was sure Aoyama was tied up securely, Shinso walked over. He gave one good chop to the pressure-point on the poys neck, and he crumpled to the ground.

Their match was over. Being the kind person he was, he went and picked up the french kid and carried him back to the monitoring room. There Shinso dropped him off in front of Recovery Girl. He woke up almost immediately, and went to stand next to Shinso after giving his thanks.

Aizawa always started with the losing party. “Aoyama, you have become better with your quirk. Keep working on strengthening your body so that you can use it longer. And THINK BEFORE YOU ACT! That is ultimately what cost you this battle. You need to learn to anticipate your opponent’s moves and plan for them.” Aoyama was back to himself smiling and nodding as if he thought of all of this himself. Pieces of glitter surrounding his head.

“Shinso, when faced with an opponent who is best at long term attacks you need to have your capture weapon be both your defense and offense. Use it as a weapon, not just a capture item. Otherwise good job in using your head and coming up with the idea to use the announcer’s voice to catch your opponent off guard.” He walked past Shinso and patted him on the shoulder. “You are doing very well.”

With those last words the purplette turned towards the smell of lemon and rain. Kaminari ran up to him and all but jumped into his arms. Sero and Mina following close behind to congratulate him on his win. The four of them went back to their seats to watch the rest of the fights.

----

The rest of the fights were as follows:

Kirishima Vs. Todoroki: Winner Todoroki

Mina Vs. Sero: Winner Mina

Midoriya Vs. Sato: Winner Midorya

Iida Vs. Tsu: Winner Tsu

Uraraka Vs Koda: Winner Koda

Jirou Vs. Ojiro: Winner Ojiro

Yaoyorozu Vs. Shoji: Winner Yayorozu

Bakugo Vs. Hagakure: Winner Bakugou

 

The fights were all over. Everyone had their commentary from Mr. Aizawa to reflect on over the weekend, and were dismissed. All of class 2A left for the locker rooms to change out of their hero costumes before going back to the dorms.

All of the other boys in the room stiffened at the smell of an Omega in pre-heat. The alphas more than the betas. Midorya being the only other male omega just shivered. He went over to Todoroki to find comfort in his boyfriend. Without thinking, Todoroki put his arm around Midoriya, comforting the omega.

Shinso walked the two of them to their lockers, and helped Kaminari to a bench. He was still so tired, and all but collapsed on top of it.

Still sitting he began to shrug his gear off. First his support item, which he placed gingerly on the bench to his left. Then his sunglasses and jacket.

He stood up reaching for his locker in front of him, but wobbled. Shinso caught him around the waist before his legs gave out. “Thank you. Man, this sucks! Stupid Pre-Heat, stupid hero training, stupid Fridays!”

Shinso just chuckled, letting Kaminari adjust himself so that he could stand on his own. The blonde finished stripping (while pretending not to notice Shinso watching), and putting on his comfy clothes. By the time he was finished, the only ones left in the locker room were Bakugo, Kirishima, Shoji, Shinso, and him.

They left the others and headed towards the dorms. They were not far, just a short 5 minute walk. But the entire way Shinso had to half carry Kaminari, the omega had little to no strength left. And they were both relieved as they got to the front door.

The first thing they saw inside was at least half of the class was on or around the couch. Jirou and Yayorozu were sitting next to each other watching the tv intently. Midoriya and Todoroki were cuddling while watching something on Todoroki’s phone. Iida was talking with Tokoyami, Sero, and Ojiro. And Tsu, Ochako, and Koda were helping Sato bake something in the kitchen.

They by passed everyone in the common area, and went straight upstairs. If any of their classmates noticed, they didn’t say anything. Knowing full well that Kaminari was in Pre-Heat and probably just wanted to be in his room where he felt safe.

---------

Denki’s room was a mess. He had felt the preheat building under his skin the entire week, setting his instincts ablaze. There were clothes (most of which were Shinso’s that he had “borrowed”) all over the floor, along with blankets and pillows of all shapes, colors, prints, and sizes.

Hitoshi helped him to his bed, and set him down carefully. He was just tuning to leave when Denki grabbed his wrist. Making him stop and turn back around to face the omega.

“Can you stay and help me with my nest?” Denki’s head was down, and there was a slight blush at the tips of his ears.

Hitoshi’s alpha was doing flips, his omega wanted him to stay and help him with his nest. An omega’s nest was their safe place. The fact that Denki wanted him to help him with it made Hitoshi ecstatic. “Of course, what would you like me to do?”

Denki looked up, gold eyes met violet. “Can you get some more of your clothes and scent them for me? I want as much of your scent in my nest as possible.”

Hitoshi nodded and turned back around to leave. But was stopped by the hand on his wrist. “Denks, I need you to let go of my hand so I can get some of my clothes from my dorm. I will be right back. Promise.” Denki seemed reluctant to let go, but after a solid 5 seconds he did.

Hitoshi hurried out of the room, the sooner he left the sooner he could get back.

After the door closed behind Hitoshi, Denki got off the bed and started gathering all of the materials on the floor into a pile. A new surge of energy coursing through him not that he was in his room and a safe place.

First he cleared a big space in a corner of the room. Then he got his comforter and fluffiest blanket. He placed the fluffy blanket down first, then his comforter. He didn’t want the blanket getting too messy during his heat.

By the time he had finished smoothing out the comforter, making sure it was straight and there were no wrinkles, Hitoshi knocked on the door. Preoccupied, Denki yelled to let him in.

The alpha’s arms were laden with clothes. Hoodies, shirts, pants, and even a few pieces of underwear.

Denki got up, and showed Hitoshi wear to put the clothes. He then had him sit on the bed, and scent all of the clothes thoroughly. He turned back around, and continued to work.

The base layer was done, the blanket and comforter were nice coutioning. He then started to make a border out of the pillows. Scenting a few here and there to make it smell of him. He had discovered a few years back that the scent of his preheat helped calm his full heat just a little bit. He didn’t know why, and from what he could tell it didn’t help any of the other omegas.

Once the border was prepared he began to loop blankets around them, reinforcing the walls. When he finished he turned around, Hitoshi was finishing with the last piece of clothing. The rest in a nice pile on the floor, waiting.

“All done, what do you want me to do now Denks?” Denki stood up, going over to the pile in front of the alpha. He looked up, and reached out a hand. Hitoshi took the hand, and was yanked to the floor.

The omega didn’t seem to be capable of speech anymore, just using his movements to indicate what he wanted. He sniffed the clothes, pulling some out. One was a large hoodie, which he shoved at the scent gland on Hitoshi’s neck.

Hitoshi took the sweatshirt and scented it some more. When he finished, the omega all but stole it from his hands. Quickly putting it on. He then shoved the other pieces of clothing that he had pulled out at Hitoshi who scented those some more as well. The hoodie was the only thing the omega put on though.

When he was satisfied, Denki took the clothes and interspersed them throughout the nest. Some he tucked into the walls of the nest. Hitoshi noticed that Denki placed more around where his head was going to be. This made his alpha happy.

When he was satisfied, Denki stood up and looked at the nest. Making sure that there was nothing wrong with the nest. He then went and sat in the middle. Hitoshi just watched, knowing that he couldn’t enter the nest if he wasn’t invited.

He didn’t watch for long though. After he got settled, Denki looked up at Hitoshi and made grabby hands. He wanted his alpha in his nest with him.

When Hitoshi didn’t move right away, he started whining and letting out distressed pheromones. Once the smell of sour lemonade and rain reached him, Hitoshi came to kneel outside the nest reaching inside.

The omega reached out and helped him in. Showing him where to step so that the nest doesn’t get messed up, and guiding him to the center. Once there he sits down and is all but tackled onto his back by the blonde.

The alpha gets comfortable, the smells of his own lavender and coffee mixing with Denki’s sweet preheat smell of lemonade and a brewing storm calming him. He turns to the usually energetic blonde and wraps an arm around waist. Nuzzling his neck.

Denki, still unable to speak, begins to purr. It is a soft, content sound that brings Hitoshi to the edge of sleep. He is just about to fall asleep with Denki in his arms, when he hears a soft “will you stay with me through my heat Toshi?” The purring had stopped, and he came back to full consciousness. “I don’t want to do this alone when I have you. I promise I have been on birth control since I presented, I just need you right now.”

There is the distinct feel of tears on Histoshi’s arm, and the smell of distressed and scared omega tainting the air.

Hitoshi hugs his omega a little tighter, and kisses the top of his head just above the lightning bolt in his hair. “Of course I will stay with you. You are my omega Denks.” He gently gripped his jaw, turning his head to face his. Denki’s face was slightly puffy and there were still tears streaming down his face.

Hitoshi kissed the omega, putting all of his emotions into the few seconds that their lips collided. “I would be honored to help you through your heat. I love you Denks.”

The scent in the air changed to that of a pleased omega. Denki’s signature sunshine smile graced his face with tears still streaming down. Though out of happiness now. He pulled Hitoshi down and collided their lips together once more before gently pulling back. “I love you too Toshi.”

Notes:

Denki/Hitoshi isn't necessarily my favorite ship in MHA, but it is what I would call my comfort ship. I don't know if that makes sense or not. I really hope you liked it, please leave a comment and/or kudos if you can!
