Chapter 1: Down Bad

Chapter Text

Midoriya had faced a lot of things before entering his third year of U.A., though technically their second year had started late because of the war. Quirks and villains that should have been unheard of, situations Heroes hadn't faced in decades, life-threatening peril at an alarming rate. You name it. He still saw Hound Dog for counseling once a week, and he still had nightmares about the things he had been forced to do to put the Paranormal Liberation Front down. It was a lot for an eighteen year old (at the time), a lot for anyone.

He'd faced other hardships too. He and Uraraka gave it a try, but sometimes two people aren't as compatible as they thought they'd be. It happens. They weren't on bad terms, per se, but they hardly spoke anymore, and heartbreak wasn't a feeling that was easy to get a grip on.

Between the war, a failed relationship, and growing up Quirkless, he at least thought he'd learned how to cope with a lot of difficulties. He was doing okay, all things considered.

But now? Now, as he walked downstairs and his eyes fell upon a sight that would be burned into his mind for a long time? This was different. A problem both new and foreign at the same time.

He was down bad.

The realization hit him almost immediately. A girl was at the coffee table with Jirou, Yaoyorozu, and Kendou. But Midorya wasn’t quite sure who she was at first, because of the way she was leaning over the coffee table.

All he could see was the most perfect ass he'd ever seen in his entire life. The black textured leggings that hugged the ass accentuated its curves and ensnared his entire vision. Both cheeks were round and plump, hugging the fabric tightly as her ass was pushed out from the way she was leaning. It bubbled out from some deliciously thick thighs, as if calling for him to stick his dick right in it.

Midoriya's hand twitched. His whole being was hit with an urge to reach out with both hands and cup that bodacious booty, and bury his face in it. Worship it. Even with his decent hand size, that bountiful backside would be more than he could grab in a handful.

He was immediately glad he wasn't wearing his gym shorts as he felt his pants tighten.

"You okay Midoriya?" The voice of Todoroki called from the couch. "You kind of froze on the stairs."

Thankfully, he snapped out of it at the call of his friend before anyone noticed him staring. But the girl turned around and Midoriya saw that the owner of the Best Ass in the Room was none other than Yanagi Reiko of class B. The two made eye contact (well, aside from one of her eyes being covered by her bangs, which for some reason was extra hot for Midoriya) and she gave him a small smile before turning to her study group.

Midoriya as well finished his descent down the stairs and walked over to Todoroki and Iida, who he was meeting to study as well. "Ah... Yeah, sorry guys. I kind of spaced out for a second."

"You've been running yourself ragged lately," Iida warned. "Perhaps you need more rest."

"Probably," he admitted, brain still clouded in a lust-covered fog. "I haven't slept the best."

"The nightmares?" Todoroki asked.

"Ah... Yeah," Midoriya asked, flipping his notebook open. It wasn’t a complete lie; he’d had nightmares about the war, and had for a long time, but they had been getting less and less as of late. He still had one at least once a week, but that was down, at least.

But there was usually only one time when he got rid of them for good.

As Iida flipped open his own books and notebook, Midoriya remembered the last time he’d gotten a good night sleep...

----------
Uraraka gripped Midoriya’s pillow as hard as she could, forgetting about her Quirk for a moment. Not that it mattered, she was holding down its weight as her eyes rolled into the back of her head. She let out a moan of pleasure as Midoriya’s hand firmly smacked her plump ass. By now, her cheeks had to be red and raw, but it was hard to feel them as Midoriya’s hips crashed into her at a furious pace. They had to have been at this for well over an hour, deep into their fourth round of love making.

“Fuck, Ochako, you feel so good...” Izuku gasped as he could feel the tension well up in his manhood. He began to pick up the pace. “I’m gonna -!”

“YES!” She gasped out, “FILL ME, DEKU-KUN! FILL ME WITH YOUR HOT -AUGH!”

They both let out satisfied groans; Uraraka begging for his cum always brought Midoriya to climax. He thrust his dick deep inside of her as it gushed out rope after rope of his seed. Once it was done quivering, he collapsed back into a sitting position and tried to regain his breath. Uraraka’s knees gave out as she fell to her side on his bed as well. His pillow floated up towards the ceiling.

Midoriya rested his head against the wall. “Phew... that was... wow.”

Uraraka gave him a weak smile from his pillow. “Y-yeah. Gah... I feel so numb, Deku...” She put her hands together weakly. "Release."

His pillow plopped down next to the bed.

Midoriya smiled back at her, and his eyes lingered over her... down to her plump breasts, and how her wide hips stood out as she laid on her side.

A glint returned to his eye as his dick stiffened again.

Uraraka saw it and frowned. “Please don’t tell me you want to go again...”
-------
Midoriya shook his head and flipped the pages of his notebook. After that, the memory would just lead to worse ones. As it was, he still felt pretty bad about remembering the nights he and Uraraka used to share, and it certainly wasn’t helping him un-pitch the tent in his pants.

Trying to take his mind off it, he did his best to focus on the math lesson Iida was giving him and Todoroki on polynomials.

“Wait,” Shoto frowned. “Go back. How did you get that answer? I got something completely different.”

Iida leaned over to look at Todoroki’s paper. “How did you get that?”

As the two discussed, Midoriya felt his eyes travel back over to Yanagi, who was studying with Yaoyorozu’s group. Now, she was sitting down with her legs crossed. And with how her thighs were sitting on top of each other gripped his gaze, Oh god, I really wish I could wrap those around my head.

He was, once again, almost caught in his almost uncharacteristic state of lust as Yaoyorozu caught him looking over there. “Are you two struggling with this math assignment as well?”

“Ah, yeah,” Midoriya replied, quickly, not realizing they had been studying the same thing as them.

“It’s my fault,” Todoroki admitted. “I’m having trouble with number four.”

“Oh, we just finished that one!” Kendou beamed. “Midoriya, help me move these tables together and we can all work on this.”

“Excellent idea!” Iida crowed.

Midoriya gulped nervously. He’d talked and done team up work with Yanagi on a small handful of occasions, but not often. And he’d always thought she was an attractive girl, but he had been smitten with Uraraka for most of his time at UA. With how taken he was with her, he wondered how much harder it’d be to focus if they were closer together. Still, there was no way to deny the request of Kendou’s without drawing attention to himself, so he just nodded, walked over, and easily moved the coffee table over.

“Aw yeah, work those muscles Midoriya!” Mina hollered from the kitchen, making him blush. He forgot that picking up a table with one hand was not how people would usually do it.

“Many thanks, Midoriya,” Yanagi said, “I should have offered to use my Quirk. I fear my brain has been taxed from these heathenous machinations, and it slipped my mind.”

He gave a nervous chuckle and looked away as he sat down. “N-no problem, it’s been a long day.” He’d remembered that she spoke in a verbose way like that, but right now it seemed really cute.

But he felt his heart practically leap into his throat and his pants shrink a size when Yanagi sat next to him. As she leaned forward to sit down, he couldn’t help but notice her rather loose-fitting shirt reveal a surprisingly large bust underneath. He turned and looked down at his notebook. Hoo boy...

“So what’s giving you trouble, guys?” Jirou asked.

Todoroki slid his notebook to the middle of the table, causing the girls to lean in.

“Wait... how did you get negative two?” Yaoyorozu asked.

“His method has baffled me as well,” Iida nodded, pointing at the second attempt at work Todoroki made. “I thought he was following along with me, but something went wrong.”

“I achieved an answer of five, is that... any better?” Yanagi asked.

“It’s a polynomial, there should be many answers,” Yaoyorozu answered in exasperation.

Nervously, Midoriya leaned over and looked at Yanagi’s work. “Here, I got the same thing as Iida, l-let m-me see...”

As she leaned closer, he caught a whiff of some sort of her hair, which smelled slightly floral. He felt his throat tighten as he caught a look of her face out of the corner of his eye. He’d never noticed how full and plump her lips were before, and immediately thought about how good they’d feel on his...and other parts of his body. Her piercing gray eye caught his and he looked down at her notebook in a slight panic.

“Um...” he gulped. “Oh... here, I think I see what you tried to do.”

He went over the equation as Iida and Yaoyorozu struggled to help Todoroki. While a very smart Hero, Shouto was really struggling with this problem. Unbeknownst to any of them, Jirou was looking between Midoriya and Yanagi, an almost amused smirk on her face. She looked over at Kendou, who was sitting next to Yanagi. They grinned at each other.

“Okay... does that make sense?” Midoriya asked, as the two finished the problem.

“Verily,” Yanagi gave him a small smile. “Your astute direction has allowed me to overcome the nightmare that is math.”

He couldn’t help but laugh at the odd compliment. “Math gives a lot of people problems. You just have to remember the process.”

“I fear many of my grades are middling, but math struggles to capture my attention,” Yanagi sighed.

“It’s because she’s up all night reading creepypastas and watching old horror movies,” Jirou snickered. “Right, Kendou?”

“Yeah, if you slept better, you might get back on the Honor Roll,” Kendou said, more in a motherly tone than Jirou’s teasing one.

“I would rather partake in the nightmares of the waking world than the world of slumber,” Yanagi said. “Sleep does not come to me so easy. I have night terrors often.”

“Ah... me too,” Midoriya said. “I get it.”

“Yeah, but like, watching scary movies seems like the opposite way to help yourself sleep,” Jirou retorted, leaning against the coffee table. Everyone else chuckled.

“You’re probably right,” Yanagi admitted, stretching her arms over her head. Midoriya fought a losing battle not to look over at her as she pushed her chest forward ever so slightly.

“Maybe we should take a break,” Yaoyorozu suggested with a sigh, now that Todoroki had finally gotten the problem correct. “I’ll make some tea, we can try a few more of these, and maybe we could all keep at this tomorrow? We have all weekend after all.”

“Yeah, I don’t know how much more I can take tonight,” Kendou sighed. “Did Aizawa make you guys do that obstacle course today? Vlad’s kicked our butts.”

Yaoyorozu stood up and headed towards the kitchen as Iida agreed with Class B’s president. Todoroki, meanwhile, put his head in his hands and rubbed his eyes. “Ugh.”

“You okay?” Midoriya asked, closing his notebook and stretching his hands over his head himself.

“I just feel like this problem was another Obstacle Course,” Todoroki grumbled, rolling his neck. “I’d almost rather fight my brother again.”

“Hey Green,” Jirou piped in, “Let’s go help Yaomomo, yeah?”

Izuku gave his classmate a small grin. “Sure thing.”

Springing to his feet, he and Jirou walked into the kitchen.

But he nearly froze as Jirou whispered to him, “So, you gonna keep eye-fucking Yanagi all night?”

She turned and snickered as she saw the look of horror on his face. “I... uh... I didn’t... I mean uh, I,” he began to stutter out, but Jirou just snickered harder.

“God, relax man, I know you aren’t like that,” she shook her head as the two went into the kitchen. She waved him over to a more secluded corner. Momo was by the stove, and Ashido and Hagakure had thankfully moved to their own rooms, so no one was hearing her. “That’s why I even said something, you usually aren’t like this.”

“I just... I don’t know,” Midoriya whispered. “I came downstairs and I’m having a hard time keeping my eyes off her.” He flinched. “I probably sound like a pig.”

“Please, you aren’t being a pig. Then I’d be treating you like Mineta.”

“Fair enough,” he conceded. “Sorry...”

“You should ask her out,” Jirou said. “Like if we study tomorrow, see if she wants to grab a drink after. I mean if that's difficult, just go for it.”

“I... don’t know,” Midoriya replied, rubbing the back of his neck hesitantly...

Jirou frowned. “Come on man... I know what happened with you and Uraraka was rough, but you got to get back in the game, right?”

“I guess,” he replied. “Just... I dunno, sometimes I still think about it.”

“I’m not telling you to marry her dude. Just try and take her out. That way I don’t have to watch you guys eye-fuck each other.”

Midoriya quirked an eyebrow. “What do you mean by each other?”
----------

Meanwhile, at the table, Yanagi was trying to quell the incredible feeling of jealousy she was feeling. It was juvenile and stupid to be jealous of Jirou, but...

A distraction came in the form of a buzz on her phone. She picked her phone off the table with her Quirk and raised an eyebrow when she saw that Kendou had texted her. She looked up at the redhead, who averted her gaze. At the other end of the table, Iida and Todoroki were talking, none the wiser.

The message from Kendou read, “so, are you gonna be able to focus on math, or are you just gonna keep ogling Midoriya?”

Yanagi fought hard to keep a small blush off her face.

She lost.

“I’m doing no such thing.” She texted back. “He just helped me with that problem.”

“Girl,” Kendou texted back far faster than Yanagi could comprehend. “You have been staring at him as soon as he came down the stairs. You were looking at him the whole time we were studying. You were staring at his muscles the whole time he was showing you that problem. You stared at his ass when he walked into the kitchen. If you look at him any harder, you’ll burn a hole in him.”

Yanagi stared at the message, more terrified of the very accurate depiction of how bad she was thirsting over Midoriya than any scary movie she’d seen lately. “I’ve done no such thing,” was the best response she could think of.

“You want to come over here everyday Midoriya isn’t working. AND Setsuna told me you asked her which pair of leggings made your ass look the best. It wasn’t hard to put two and two together,” Kendou’s reply came.

Kendou repressed a snicker as she saw Yanagi flinch in defeat. The most the ghostly girl could muster as a retort was, “That treacherous, dinosaur-loving harlequin. I will have words with her.”
----------
“Yeah man, she’s been staring at you like, all week. Kinda surprised you hadn’t noticed,” Jirou laughed. “Anyway, just my advice. Hey, Yaomomo, you need a hand?”

Midoriya followed the rocker in a rather stunned silence as they helped the Vice President bring out the tray of tea and snacks to the table. He suddenly felt very nervous to go back out to the common area and sit by Yanagi.

Not much more studying was done that night, as after some tea and one more problem, everyone decided to call it quits. The girls were going to head over to the Class B dorms with Kendou and Yanagi; apparently the girls were doing a game night for the girls of both classes.

“We’ll come by after lunch and knock out the rest of these, yeah?” Kendou suggested as she was packing up.

“Works for us,” Iida nodded. “Have fun with your game night!”

“We should do a game night. A Guys Game night,” Todoroki suggested. “I have Throw Throw Burrito.”

“Oh, that does sound fun,” Midoriya agreed. “Alright, see you guys tomorrow!”

He made rather awkward eye contact with Yanagi as the groups separated. Shyly, the two exchanged small but genuine smiles with each other.

Midoriya felt pretty good about that, trying to psyche himself up to ask out Yanagi, just like Jirou had suggested.

Then he turned around. As he did, he made another round of uncomfortable eye contact. This time, with Uraraka as she came down the stairs with Asui, Ashido, and Hagakure. He and Uraraka made eye contact, and both of them looked away as quickly as possible.

As the girls left, he suddenly didn’t feel that great anymore.

“Hey, let’s see who wants to play some games,” Todoroki suggested, eager to start the weekend off right.

“Yes, I’ll ask the guys,” Iida beamed.

“Will you help me set some games up?” The two-toned hair boy asked, turning to Midoriya.

“Huh?” The greenette blurted out, pulled from a trance. “Oh... sure.”
-------

Midoriya had fun with his friends, sure. It was a good distraction, as friends often are, but then it came time for sleep.

And he was alone with his thoughts.

And after running into Uraraka, his thoughts were her words.
-------

Uraraka saw his now-erect dick and frowned. “Please don’t tell me you want to go again...” She shifted into a sitting position. “We’ve gone for four rounds already.”

Midoriya lifted his leg to hide his manhood from her view and propped his arm on it as he looked away, guiltily. “S-sorry. You’re just so beautiful.”

“Sweet talk isn’t going to work on me,” Uraraka sighed, aggravated. She stood up and paced his floor to where her shorts were. “It’s after midnight and I’m exhausted, Deku.”

“I wasn’t trying to pressure you,” Deku added. “Are you... upset with me?”

He got slightly nervous as she seemed to lock up at the question. She turned around, biting her lip. “I mean... I kind of wanted to just chill tonight. You knew that. Every night seems to turn into this marathon sex session with you though.”

“I’m sorry,” he muttered, away from her. “I... thought you liked it.”

“It’s not that I don’t like having sex with you,” Uraraka explained, “But to be honest... sometimes I just do it because I feel like you want to do that all the time. Like it's great sometimes but sometimes I just feel... I dunno, obligated?”

His eyes widened, and she immediately interjected, “You didn’t pressure me, or make me do this against my will, before you get all down on yourself. It just... I think your sex drive is way higher than mine and I feel bad turning you down.”

“Oh...” Was all Midoriya could muster. “Well, I’m glad you told me. You don’t have to feel bad for turning me down, I understand if you don’t want to as much as I do...”

“I don’t think it’s that simple, Deku...” She whispered.

“Huh?”

“I just... it's a big difference, honestly,” Uraraka explained. “We might not be compatible.”

His heart began pounding in his ears. This conversation was taking a turn he never expected, and the panic began to well up in his chest. “What are you saying?!”

They made eye contact again, and there was a hurt in her eyes. Neither said anything for what felt like an eternity. Finally, she managed to utter out a, “sorry,” and ran from the room.
-------
They hadn’t spoken since. A week or so later, he’d overheard Mina talking about how she was dating Asui, and it didn’t take much for Midoriya to figure out what Uraraka meant by, “compatible.”

It made him afraid. Afraid of his sex drive, afraid of intimacy, afraid to overwhelm and drive someone else away.

He tried to think of something else to get the thought out of his head.

And his thoughts drifted to Yanagi, and asking her out.

And of how good her ass looked.

Without thinking, his hand slid down his pants.

Just to help me sleep, he lied to himself as he slowly stroked his almost-erect cock.
