Work Text:
There were few things more satisfying than helping out on a successful raid. Sure, Nezu wasn't part of the boots on the ground team, but he compiled all of the information for them and briefed the teams. He also provided overwatch in case there was a disaster.
This raid had gone as well as one could ask. All the criminals were in custody, no heroes were seriously hurt, and best of all, no casualties. He was even able to come home a day early. Well, a night if the setting sun was anything to go by.
Nezu stepped into his house and closed the door behind him. As he peeled off his shoes, he saw Aizawa's shoes had another pair next to them. Nezu recognized those shoes instantly. They belonged to Hizashi Yamada: the best friend of Aizawa.
The two had bonded after Aizawa's victory at the sports festival, and when Aizawa transferred to heroics in his second year, Yamada was the first one to greet him. Oboro Shirakumo was second. And after Oboro Shirakumo's death, Yamada was a big help in keeping Aizawa afloat.
And was probably the only one besides Nezu who could get Aizawa to take a break from training.
This was great news. Nezu could buy the boys dinner and celebrate the victory. He set his messenger bag down and headed toward the stairs. After letting Aizawa know he was home and telling him to order something, Nezu would take a shower. A nice long shower.
It would get off the filth of some of the people he had to work with. Like that one hero who sneezed without covering her mouth. Or the police correspondent who sat next to him and talked with his mouth full of sushi.
Nezu was still finding half-eaten rice in his clothes.
As Nezu made it up the stairs, his ears twitched. He could hear odd sounds coming from Aizawa's room. It sounded like him and Yamada were sparring. How many times had he told the boys to take it outside? Especially after Aizawa shattered that vase with his binding cloth.
Aizawa's room was at the end of the hall, and it looked like his door was open. Nezu made it toward the door and turned. His mouth was opening, but he went stiff as a board at the scene in front of him.
Aizawa and Yamada were tangled up on the bed, but it seemed like Yamada was the one on top. And they were most certainly not sparring. Not with Aizawa's boxers and pants down at his knees and Yamada's undergarments just discarded by the bed.
Nezu knew he shouldn't stare, but he wasn't sure what to do. This was all foreign to him. Intimate contact like this was something that had never interested Nezu. He was quite content with his small group of friends, and he never wanted to do this with them.
A strangled noise left Aizawa, and his hand gripped the bedsheet. That noise knocked Nezu out of his stupor, and he blinked. Nezu knew exactly what he needed to do.
Leave.
Nezu stepped backward and heard Yamada curse, “Shit! I think your dad is home!”
Nezu quickly retreated toward the stairs, and he heard the boys scrambling off the bed. Nezu waited about fifteen seconds before he spoke loudly, “Shota! I'm home.”
“Be right there!” Aizawa called back. His voice was... not normal. Nezu did not like how hoarse and strangled it sounded right now.
“Hey, Mr. Nezu!” Yamada said as he stumbled out of the room. He was holding his hoodie in his hands, and Nezu would bet that Yamda's pants were unzipped. And his shirt was backward. His hoodie was pressed against his crotch.
Yamada was breathing heavily, and his face was flushed. Nezu felt a growl building in his throat.
Hizashi Yamada had been having sex with Shota Aizawa. With Nezu's son.
Aizawa appeared a moment later, face just as flushed. He was wearing his pants and had a jacket pulled on. He rested against the door, with the frame hiding his lower half. Aizawa spoke, “Hey, how did it go?”
Nezu tried to open his mouth, but all he could do was stare at the two teenagers who had just been having sex. Now that the initial shock was gone, it was starting to be replaced by anger.
Nezu needed to keep his face under control and not let them know he was angry. Especially because of how sore of a subject this was for Aizawa.
While Nezu had spent the last few years nurturing his relationship with Aizawa, he also knew that Aizawa's sexuality was a sore subject. It was the last thing his father berated him about before being arrested. It was the reason Aizawa's father nearly beat him to death if Nezu hadn't stepped in.
So he didn't need Aizawa to think for a single second that Nezu was mad because they were having sex.
Which Nezu was definitely mad about, but not because Aizawa was gay.
Not even because he was having sex with his best friend.
“Mr. Nezu, you okay?” Yamada questioned. His breathing pattern wasn't as relaxed as normal. There was a bit of sweat on his face, and that smell...
When Nezu smelled it before, he had thought it was because the boys hadn't showered after training. Not because they were having intimate moments.
“Nezu,” Aizawa began, as concern came to his face. He stepped into the hallway and immediately hunched in on himself. It didn't do anything to hide what his baggy pants already did. There was a bruise on Aizawa's neck. Not from training.
How did Nezu not see the signs earlier? Were the two boys even doing this properly? Were they being safe about it? What constituted safe sex for humans anyway?
“Nezu,” Aizawa said as he moved toward Nezu's side and knelt by him. Aizawa studied him with concern. “Hey, what's wrong? Are you hurt?”
“No,” Nezu finally answered, and he had to grit his teeth to keep from growling at Yamada. Nezu took a step back. It would be best to make some kind of excuse and retreat. Instead, he just retreated. Nezu was down the stairs and stepping into his office before he realized it.
Even as Aizawa called after him.
Nezu stared at the computer screen in front of him. His phone rested in front of him. While he still felt a bit of anger, it had gone away after some research. And Nezu had learned many interesting things about how humans, particularly males, had sex.
Though some of these videos were quite unbelievable.
Nezu moved his gaze to his phone and typed in the number of his best friend. And an expert on the topic. It only took Chiyo seventeen seconds to answer.
“Nezu?” Chiyo questioned. “Did something happen?”
“Yes,” Nezu replied.
“Who is injured?” Chiyo pressed.
“Oh!” Nezu realized. “No, there were no serious injuries in the raid. I am already back home. I'm afraid my problem is more of the... teenager sort.”
“Ah. What did you do this time?” Chiyo asked.
“I walked in on Yamada and Shota having sex,” Nezu said. There was a long silence on the other end. “...Chiyo?”
Chiyo took a deep breath, “Okay. Tell me exactly what happened.”
“Well, Yamada was-”
“Not that!” Chiyo interrupted. “What did you do?”
“Nothing,” Nezu replied. “I stepped away. Yamada did not see me, but he said that I was home. I moved to the stairs and announced my arrival. I do not think they know that I saw everything, Chiyo. That Yamada was-”
“I don't need those details, Nezu,” Chiyo insisted.
“I know that Yamada and Shota are courting each other,” Nezu began.
“Dating,” Chiyo supplied. Dating. Right. The step before an engagement which was the step before marriage. Granted, some people skipped the dating phase or never made it out of it.
“Yes. They are dating,” Nezu confirmed. He frowned. “...I think. Shota has not told me.”
“Do you think he is going to?” Chiyo asked.
“I don't know,” Nezu admitted. He had seen the stolen kisses between Yamada and Aizawa. How Yamada would stay over and sleep in Aizawa's bed, where the two of them would end up cuddling. “Would he?”
Nezu knew Aizawa was gay. Aizawa knew that Nezu knew. But they had never spoken to each other aloud about it. Maybe that was Nezu's mistake. He didn't tell Aizawa that it was okay. That Nezu would never judge him.
“I do have a problem, Chiyo,” Nezu said before his friend could respond. “I need to know how to talk to Shota about sex. I want to make sure he is being safe about it. And my research-”
A long-suffering sigh interrupted his words.
“Research?” Chiyo asked.
“Yes,” Nezu confirmed. “Most parent blogs I found were about how to stop your children from having sex, so I figured I would need to watch some to supplement my education.”
“You're watching porn to find out how to talk to your son about sex?” Chiyo questioned.
“It is the best way,” Nezu stated. Chiyo snorted. “How should I talk to him?”
There was silence for a few seconds before Chiyo sighed again, “Make sure the boys are using lube. It will prevent them from tearing anything. And condoms. You-”
A knock on the office door made Nezu look up. He heard Aizawa's voice from the other side, “Dad? Can I come in?”
Nezu frowned. It wasn't often that Aizawa called him Dad. Was something wrong? Nezu cleared his throat, “I must go, Chiyo. Thank you.”
“This is going to be embarrassing,” Chiyo warned. “Good luck.”
“Thank you, Chiyo. Have a good night,” Nezu said. He ended the call and looked at the door. “Come in.”
Aizawa stepped into the office. He was holding onto a cup in his hand. Steam rolled off of it, and Aizawa walked toward the desk. The cup was set down, and Nezu tilted his head.
“I know you want to keep this hero stuff from me,” Aizawa began as he rubbed the back of his neck. “But, I'm going underground when I graduate. I can handle these bad things. Y...you can talk to me, Dad. I'll listen and not say anything. Don't bottle it up inside. Like you told me.”
“You made tea,” Nezu began as he looked at the cup.
“I thought it would make you feel better,” Aizawa explained.
“I feel fine,” Nezu rebutted.
“Dad, you didn't answer me,” Aizawa said as he crossed his arms, but there was concern in his eyes. “You were just standing on the stairs, looking like you had seen a ghost. I thought something bad had happened, and then you just walked away and didn't say anything.
“You can talk to me,” Aizawa promised. “I'll help you however I can. Please just-”
“I saw you and Yamada having sex.”
Aizawa froze. His face started to turn red, and his hands started to shake before he gripped his arms tightly. While the embarrassment was clear with his red face, his eyes were full of fear. Nezu frowned.
“Shota, I know you are gay. I know that you two are dating,” Nezu began. “Or having a, what is it called, friends with benefits situation. I would never judge you for that.”
“Y...y....you saw u...us,” Aizawa stuttered out, and he tried to hide his face. His hair had recently been cut, so it wasn't long enough to fully hide his expression.
“Yes,” Nezu said. “It was very awkward, and I stared longer than I meant to because I didn't know what else to do.”
“You saw us,” Aizawa repeated as his face somehow turned redder.
“I did,” Nezu confirmed. He sat forward. “There is one thing that disappointed me, Shota.”
The pain, no, the hurt that crossed Aizawa's face made Nezu realize he had chosen the wrong words. Nezu spoke quickly, “Why was he on top of you?”
“W...what?” Aizawa asked as the hurt slowly became replaced by confusion.
“Yamada was on top of you,” Nezu repeated. From his understanding of sexual relations, there were only three reasons for it.
One: procreation.
Unless Nezu greatly misunderstood human anatomy, that was not in the cards for the two boys. In fact, it better not be in Aizawa's cards anytime in the foreseeable future. He was not ready for a child. But, Nezu would digress.
Two: nature.
Apparently, humans just had sex for fun. Which Nezu did not understand.
Three: dominance.
So even if this had been pleasure between the two, why was Hizashi Yamada the one on top?
“I don't...” Aizawa trailed off and hid his red face again.
“You are clearly the alpha in this relationship, so why was Yamada on top of you?” Nezu asked. It didn't seem possible for Aizawa to turn anymore red, but Nezu was learning a lot about the male body today.
“Sit down,” Nezu commanded. Aizawa hesitated for a few seconds before slowly sitting down. He crossed his arms and stared down at the ground. “Shota, I have known that you are gay. It is no surprise to me, and I will always support you. I just don't know why you are letting Yamada be on top.
“Is it because you wanted him to think he is the dominant one?” Nezu asked. Aizawa buried his face in one hand. Nezu frowned. Aizawa did understand that Nezu supported him, right? “You must be careful. He may start to believe it.”
Aizawa mumbled something, but even with superior hearing, Nezu struggled to make it out. He finally spoke up, “Can you repeat that?”
“I... wanted... to try it,” Aizawa mumbled.
“Try being on the bottom?” Nezu asked. Aizawa made a noise and dug his fingernails into his forehead. Nezu frowned and tried to think of what to say. “...how was it?”
Aizawa made that noise again, sounding like he was in pain. Nezu's frown deepened, “Did he hurt you?”
“No!” Aizawa protested. He lifted his head before lowering it again and digging his fingers back in. “Not on purpose.”
“It's okay,” Nezu began. “I watched a video-”
Aizawa made that noise of pain again. Nezu's eyes widened, “Oh! It hurts to sit, doesn't it!?”
Somehow, Aizawa became redder.
Maybe this was a medical problem.
“Shota, are you feeling okay?” Nezu asked.
“No,” Aizawa muttered.
“Did Yamada hurt something when he-”
Aizawa squeaked again, and his fingers dug in more. Nezu frowned, and it took Aizawa a moment to ground his words out, “Stop. Talking.”
“We have to talk about this,” Nezu began. Aizawa shook his head. “I approve of you having sex, Shota.”
That pained noise was much longer and deeper this time. Nezu opened his mouth and then blinked.
“Oh,” Nezu realized. “I'm embarrassing you right now, aren't I?”
There was the smallest of nods. Nezu took a breath and tried to think. He knew that Chiyo warned him this would be embarrassing, but he didn't feel embarrassed. This conversation was a rational one to have. Aizawa was nearly eighteen and would be graduating soon. He had earned the right to make his own decisions.
It only made sense for him to talk about safe sex.
Nezu knew that schools touched on the topic, but even UA lagged regarding the topic of gay sex. Relationships between men and women were all that the textbooks were about. Not the intricacies of a same sex relationship.
So Yamada and Aizawa had nothing to tell them how to be safe.
“Shota, I want you and Yamada to be safe about this,” Nezu began again, a bit more gently this time. “I don't want either of you to hurt the other. We don't have to go into too many details, but I need you to do two things. Please look at me.”
Dark eyes slowly looked at Nezu, peeking through fingers that were still digging into Aizawa's face. Nezu gently reached out to grab that hand and pull it away from Aizawa's face.
“Are you using condoms?” Nezu asked. That pained look appeared once again. “If you are not, you need to. It will protect both of you. What about lube?”
The smallest shake of a head. Nezu nodded, “You need to use lube before you two... get down to business. I can show you.”
Aizawa's entire body jerked like he had been punched. His face was still doing an amazing impersonation of a tomato.
“Or I can tell you,” Nezu decided. “You start with one finger to-”
“Please stop talking,” Aizawa begged, and it was a tone Nezu had never heard before.
“I know what to do,” Nezu said as he stood from his desk. Aizawa's eyes slowly moved to him. “Let's go buy condoms together.”
Contrary to popular belief, Nezu was quite strong. Being an animal gave him natural strength, and the experiments done on him made him even stronger. He had to train to hone that strength, but now, he knew how to harness that strength for when he needed it.
Like now.
“Come on, Shota,” Nezu said as he dragged Aizawa behind him. It had been a bit of a struggle to get him out of the office, but the chair he had grabbed onto offered no resistance. Nor could he get a grip on the doorframe of the office. Aizawa had tried digging his heels into the ground.
But something as simple as that wasn't going to stop Nezu.
“This won't take long,” Nezu promised as he opened the door and stepped outside, still dragging Aizawa. As he made it outside, he was met with sudden resistance. Nezu looked back to see that Aizawa had grabbed onto the wall and had one leg wrapped around it to keep himself from going anywhere else.
“Shota, we can do this the easy way,” Nezu began.
“I don't want to do this,” Aizawa said through gritted teeth.
“But we have to,” Nezu stated. Aizawa's hand was trying to pull out of his, but Nezu could not allow that to happen. Aizawa used his free hand to push against the door frame and try to get himself back inside. Nezu sighed.
He wanted to get dinner after this, but everywhere would be busy if they didn't hurry. Time to end this quickly.
Nezu turned and placed both feet to the door frame, pulling back on Aizawa. There was a look of surprise on Aizawa's face, and Nezu pulled Aizawa forward as he pushed back on the door frame with his feet.
And promptly ripped Aizawa forward and into the door frame. Nezu tried to catch his son and his footing, but they both crashed to the ground. Nezu groaned and heard a groan from above him. Aizawa slowly rolled onto his back.
An unamused face appeared above them. Chiyo shook her head and spoke, “Why are you trying to murder your son?”
“He hates me,” Aizawa groaned.
“I am doing this because I love him,” Nezu argued. “I was going to take him shopping for condoms and lube.”
Aizawa groaned and placed both hands to his face. There was an amused look on Chiyo's face as she raised two items above Aizawa and promptly dropped them on his chest. He peeked through his fingers, and the red on his face trailed down his neck.
“Use lube before and after putting on the condom,” Chiyo warned. “Look up how to prepare yourselves. And make sure that the two of you communicate. And Nezu, leave the poor boy alone. He's going to have trouble looking you in the eye after this.”
“I just want Shota to be safe,” Nezu said as he looked at Aizawa. His son slowly sat up and grabbed the gifts from Chiyo. He stared down at the ground.
“Thanks,” Aizawa mumbled as he stood.
“We can go for dinner,” Nezu offered.
“Not hungry,” Aizawa said as he hurried inside in record time. His normally quiet footsteps were much louder, allowing Nezu to trace him up the stairs and tell when he tripped on the second-to-last step. Nezu took a step forward..
“He's embarrassed, Nezu. Give him some space,” Chiyo ordered.
“I wasn't trying to embarrass him,” Nezu began. “I just wanted to make sure he was safe.”
“Learning that their father walked in on them having sex is one of the most embarrassing things a teenager can go through,” Chiyo stated. “It doesn't help that you gave him the talk on the same day and then tried to drag him to buy condoms and lube. Did you tell him how to use the lube?”
“I tried to,” Nezu said. Chiyo laughed.
“Nezu, promise me that you will never talk to your son about sex again,” Chiyo chastised.
“I'll try,” Nezu began as he looked back at the stairs. He frowned. “What should I do?”
“Order dinner. Text him that you got something and go to your office to eat,” Chiyo said. “He's going to avoid you for the next week. And don't be surprised if Yamada avoids you too.”
“I wish I could have helped more,” Nezu began.
“Trust me, Nezu. You helped plenty,” Chiyo said.
“According to you, all I did was embarrass him,” Nezu said as he crossed his arms.
“You did,” Chiyo agreed. “You also acted how a parent would. You didn't yell at him, berate him, or hit him like his birth father did. You treated him as you would someone who was your flesh and blood. It may have been embarrassing for him, but it was a good thing. He may not realize it, but you treated him just like a loving father would. It's going to mean a lot to him.”
“You think so?” Nezu asked after a few moments.
“I know so,” Chiyo said, and she gave Nezu a rare smile. He smiled back. “You're a great father, Nezu. Now, why don't we go get some food, and you can tell me all about those videos you were watching. I know you're dying to tell someone about it.”
