Naughty Thoughts

Between their jobs as Pro Heroes and any other careers they pursued, it was rare indeed for the Class A students to have any free time to themselves. It was even rarer for them to hang out together thanks to their conflicting schedules. This was especially true for Ochako. Juggling her work as both a Pro Hero and the founder of the Quirk Counseling Expansion Project was exhausting work, so she was grateful for any bit of respite she could get. Today was one of those rare moments of respite and she decided to spend it at Kiyashi Ward Shopping Mall with her friend, classmate, and fellow Pro Hero Mina Ashido. The two sat on a bench eating ice cream. But though she wanted to relax a bit, there was a rather vexing issue that prevented her from doing so.

The issue in question involved a certain greenette who just so happens to be her boyfriend.

Yes, she and Izuku Midoriya had been dating for the past eight years since graduating U.A. They had feelings for each other since their U.A. days, so when they decided to make it official, the news came as no surprise to the other Class A students. And while the relationship was lovely, it wasn't without its challenges. Apart from Pro Hero work, her running the Quirk Counseling Expansion Project and him being a teacher at the most prestigious school in Japan meant that they didn't have a lot of time for themselves. But recently, Izuku had been pulling a few all-nighters, coming home later and later. They say absence makes the heart grow fonder, but it can also plant other seeds. Doubt and paranoia being chief among them.

"Is Izuku cheating on me?"

That was seed of doubt that had been planted in her heart, the question that nagged at the back of Ochako's mind. It was absurd, really. The very idea was patently ridiculous. And yet as much as she tried to banish the thought out of her mind, the question haunted her every step. Call it women's intuition or just sheer paranoia. Deep down she knows that Izuku would never do something like that, but she couldn't shake off the constant stream of what-ifs that assailed her mind. Before she got too deep in her thoughts, she was brought back to reality by the sound of Mina's voice.

"So, you gonna eat that ice cream already, or are you just gonna have a staring contest with it?" she asked, pointing to the currently melting ice cream cone. "Because so far, the ice cream seems to be losing."

"Oh, sorry." Ochako sheepishly replied. "I've just got a lot on my mind, that's all."

"Don't need to be a psychiatrist to see that." Mina said. "So, yen for your thoughts?"

Ochako paused for a moment. She wasn't sure if she wanted to involve others in this given that she was going off of an admittedly baseless hunch. But of all of Class A, Mina was the one who kept pushing her to get together with Izuku, so she felt she could at least confide in her. With a heavy sigh, she finally spoke. "Hypothetical question: Say there's this girl who thinks her boyfriend might be... cheating on her. How would she go about finding evidence?"

"Is this about Izuku?" Mina bluntly asked, having clearly seen through Ochako's story.

"Jesus, Mina, was it that obvious?" Ochako asked, blushing.

"Well you're not the best liar." Mina said. "So you think Izuku is cheating on you?"

Ochako sighed again. "Yeah, I know you probably think I sound crazy, huh?"

"A little." Mina replied. "I mean, Izuku? Cheating? Guy couldn't cheat on a math test, much less his girlfriend."

"You think I'd know that." Ochako said. "And yet I just can't shake the feeling. I mean, he's been coming home later and later."

"Well, he's a Pro Hero now thanks to that suit we all helped build for him." Mina pointed out. "Plus, he's a teacher at U.A, so he's obviously going to be busy."

"That's what I keep telling myself." Ochako said. "But then I can't help but think that instead of working at U.A, he's fooling around with some hot secretary. Or when he's out doing hero work, he saves a woman and she ends up charming him into her home. Or when he's hanging out with the guys, they take him to a strip club and he ends up with a hooker."

Mina couldn't help but laugh. "Okay, I think you watch way too many soap operas." She wrapped an arm around Ochako. "Girl, do you even hear yourself?" She asked. "Anyone with functioning eyes and a pair of brain cells could see that you're the only woman for him. You're practically the center of his universe. He worships the ground you walk on. Hell, I bet his dick would shrivel at the thought of being with a woman who isn't you."

"Jeez, you didn't have to say it like that." Ochako replied, looking away with a blush on her face. While she admired how open Mina could be, she could be a bit too crass at times. "Still, you could be right and I'm just being paranoid. I just wish I had a way to find out for sure. If nothing else, than for my own piece of mind."

"Perhaps I could help with that." A familiar voice said from behind. The pair turned to see none other than Mei Hatsume standing behind them with a box in her arm. "Hey, Mei." Ochako greeted. "What are you doing here?"

"I was in the neighborhood and I couldn't help overhearing your problem." Mei replied as she walked in front of them. "And I think I might have the solution. Remember that suit we made for Izuku? Or the mech suit All Might used to fight All For One way back when? That got me thinking: What if I could make support gear that could replicate the Quirks of Pro Heroes who lost their Quirks? Or make gear that could augment said Quirks? So, I decided to start small. Remember Ragdoll from the Wild Wild Pussycats? Recently, I made her a pair of goggles that could replicate her Search Quirk that got stolen by All For One, allowing her to take to the field once again. And that brings us to now. You know Mandalay's Telepath Quirk allows her communicate with others using her thoughts. The one weakness is that is a one-way communication, meaning she can't hear others' thoughts. That's where this baby comes in!"

Mei opened the box and pulled out... a pair of cat-ear shaped headphones. "Ta-da!" Mei exclaimed. "What do you think?"

"I think it looks just like the headphones the Pussycats wear." Ochako flatly replied.

"Oh, that's where you'd be mistaken, my friend!" Mei replied. "Basing if off of the sensors used in the Tartarus prison, I managed to create a replica that in layman's terms, acts as a radio for brainwaves. So, theoretically, it should allow the user to hear the thoughts of others, which for Mandalay, would eliminate her Quirk's one weakness."

"Wait, back up. You basically created a mind-reading device?!" Mina exclaimed in utter disbelief. "That's insane. Even for you."

"Oh ye of little faith." Mei said as she offered the headphones to Ochako. "If you don't believe me, try it yourself." Ochako and Mina both exchanged skeptical glances with each other before shrugging their shoulders. Ochako took the headphones and put them on. "Now press the button on the side and concentrate." Mei commanded. Ochako did as she was told and pressed the button. She then took a few deep breaths to concentrate. And that's when it happened. She could hear the thoughts of all the people around her as they passed by. It was extraordinary. "So, what do you think of my new baby?" She heard Mei's voice in her head, startling her and snapping her back to reality as she hurriedly took off the headphones.

"Holy shit, it worked!" Ochako exclaimed.

"Glad to hear it!" Mei said. "Now, it's still a prototype, so I need to iron out any kinks. So when I heard about your dilemma, I figured this was the perfect way to kill two birds with one stone: I could help you out and gather data in the process. So why don't you try this on Izuku and tell me the results?"

"Mei, you're a lifesaver!" Ochako said. "This is perfect!" Slamming her fist into her open palm with a devious smirk, she thought to herself. "Just you wait, Izuku, I'll find out whatever secrets you may be hiding."


Later, at Izuku's and Ochako's apartment...

Having filed away the last of the paperwork, Izuku sat on the bed reading a book. Thankfully, there was no surprise villain attack which meant he could come home early for a change. As fun as it was teaching the next generation of heroes as well as Pro Hero work, it could be exhausting. This is especially true when a villain attack happens and Izuku is forced to deal with the aftermath. All the more reason he was grateful today was Friday as that meant a nice, long, relaxing weekend with his darling Ochako. The thought of having some alone time with his girlfriend made him smile. Sometimes he still found it hard to believe that he'd ever be dating someone, let alone someone as beautiful and kind and lovely as Ochako. Before he could get too deep into his romantic thoughts however, he was brought out of it by the sound of Ochako's voice.

"Hey Izuku." Ochako said. Izuku looked to see Ochako sitting on the bed next to him, having just changed into her sleeping clothes with consisted of a simple black tank top and a matching black thong. On her head, she wore what appeared to be the headphones worn by the Wild Wild Pussycats. That had Izuku raising an eyebrow. "Are those Mandalay's headphones?" he asked.

"Yeah I was at the mall earlier today and I saw a replica of these at one of the stores, so I just couldn't resist." Ochako said. "So what do you think?"

"Definitely looks good on you." Izuku replied as he went back to reading his book. Seeing her chance, Ochako pressed the button on the side of the headphones. "Alright, Izuku." she thought to herself with a smirk. "Let's see what you're really thinking." Remembering Mei's advice, she took a deep breath to clear her mind and concentrate. It wasn't long before she heard Izuku's thoughts loud and clear:

"Thank God it's Friday." Izuku's thoughts rang out. "Between work at U.A. and late night patrols, this week's been a killer. But they say good things come to those who wait. And what awaits me is a nice, long, relaxing weekend at Shirahama Beach with the love of my life. And that also means she'll finally get to wear that new bikini she bought the other day."

"Wait, he actually remembered that?" Ochako thought. She had bought the outfit for their beach trip this weekend and showed it to Izuku to see what he thought of it, but he was so engrossed in work that he didn't really comment on it outside of "It looks nice".

"I was too busy with work to notice, but looking back on it now, she looked so damn sexy in that outfit." Izuku's thoughts continued. "Then again, she could make any outfit look sexy. Though admittedly, that's a bit of bias on my part since she's my girlfriend and all. Oh, I can see it now: The two of us relaxing on the beach, me rubbing suntan lotion all over her beautiful body, us enjoying a nice dinner as we watch the sunset, having a relaxing nighttime soak in a hot spring. And maybe, if I play my cards right... she'll let me see her out of her bikini."

"Wait, WHAT?!" Ochako mentally exclaimed, a blush painting her cheeks a brilliant shade of red at the rather brazen statement. Meanwhile, a rather dreamy smile crossed Izuku's lips as his thoughts continued to voice themselves. "Just the thought of it: Her beautiful breasts, her delicious curves, her slender legs, us wrapped in each other's arms and whispering sweet nothings in each other's ears, me peppering her body with kisses. Oh, just thinking about having that perfect body of hers all to myself is getting me all hot and bothered."

Izuku sighed. "Sometimes I still wonder how I got so lucky. Me, a Quirkless nerd from Aldera Middle School who got to meet his long-time idol, wield the most powerful Quirk in existence, and save the world from the ultimate evil. Now I'm a teacher at the most prestigious school in Japan and I get to be a Pro Hero again even without my Quirk thanks to all my wonderful friends. And the best part? I have the most loving, strong, smart, kind, patient, beautiful, and downright sexiest girl in the whole world at my side through it all." Another sigh escaped Izuku's lips. "I'm so blessed." he spoke aloud.

Meanwhile, Ochako just stared at Izuku with her eyes wide and her face redder than Kirishima's hair. She couldn't believe what she had just heard. She figured that Izuku thought about her, but she had no idea how lewd and erotic his thoughts actually were. But the initial shock was soon replaced with the unholy trinity of embarrassment, shame, and guilt, causing her to look away. Here was Izuku hard at work protecting the city as a Pro Hero and raising the next generation of Heroes as a teacher at U.A. and all this time he's been thinking of her. And how has she repaid his devotion? With doubt and distrust? God, she feels like such a fucking idiot right now. Mina was right all along: She didn't need some stupid machine to tell her what should've been blatantly obvious.

But it didn't take long for her embarrassment and shame to give way to two other emotions: Pride... and arousal. Izuku was a famous Pro Hero. He probably gets swarmed by cheering fans and swooning women on a daily basis. Yet despite being surrounded by temptation, his eyes and his heart remained true to her and her alone. The thought made Ochako smile with pride. And to hear all of those erotic thoughts he had about her. They had been intimate before, so Ochako knew Izuku was no prude despite appearances. But to hear how much and how deeply he desired her?

Well, Izuku wasn't the only one getting hot and bothered. And thanks to Mei's device, she knew the best way to make it up to him.

Ochako turned back to face Izuku, her expression now a devious smirk. "Ochako?" Izuku asked, having noticed Ochako staring at him. "Ochako? Yoo-hoo?" He waved a hand in her face to get her attention. "Earth to Ochak-" Before Izuku could react, Ochako grabbed him by the shirt and crashed their lips together in a passionate, hungry kiss, her tongue pushing its way into the greenette's mouth. Though it felt less like she was kissing him and more like she was trying to suck the air right out of his lungs. Eventually, after what felt like an eternity, she broke off the kiss, leaving Izuku gasping for air. "Ochako?!" he asked after regaining his voice.

Ochako responded by pushing him onto the bed. "Ochako, what the hell?!" Izuku asked. Then his eyes went wide as Ochako sat on top of him, positioning herself directly on his crotch. She then took off her top, giving Izuku a full view of her rather impressive bust. "Like what you see?" She asked in a seductive tone, the smirk still on her face.

"Uh... yeah. Yeah, I do." Izuku replied, a touch confused by what was happening. Meanwhile, his inner thoughts rang out, "I've never seen Ochako so... bold before. And I gotta admit, it's kinda hot."

"Glad to hear it." Ochako replied, her smile growing wider at having heard his thoughts. "After all, this is what you wanted right? My beautiful breasts? My delicious curves? My slender legs? Having my perfect body all to yourself?" As Ochako spoke, she began grinding against Izuku's crotch in a clear attempt to get him excited. "Well, I'm giving you what you want." She leaned in closer to Izuku's face, her auburn eyes meeting his emerald eyes. "You've been working so hard lately, and I think such hard work deserves a reward, don't you?" She asked, running her hand through his hair before trailing her fingers down his cheek. "So I hope you didn't plan on sleeping tonight... cause I'm about to ride you until you see stars."

She then gripped his chin and forced him to look at her, her facial expression hardening as her tone became more commanding. "And you're not leaving this room until I'm satisfied. Now off with the clothes."

Izuku blinked a few times as he stared at Ochako. Now most boys would be a little unnerved by their girlfriend's sudden 360 shift in personality and their sudden demand for sex, but what's Izuku's response? He simply looks away with that trademark dorky smile. "Well, if you insist." He coyly replied. "Mom always said never look a gift horse in the mouth." Meanwhile, his inner thoughts were screaming with excitement, "OH HELL YES! BABY, LET'S FUCKING GOOO!"


Hours of intense, passionate, bed-breaking sex later...

The room was quite a mess. If someone were to come in right now, it would look almost as though a hurricane had passed through it. If the hurricane in question were two hormone-addled adults going at it like a pair of wild beasts in heat, especially when Ochako decided to get kinky with her Quirk and the two ended up having sex in Zero Gravity. Izuku honestly lost count of how long they went at it, but the two lovebirds eventually hit the limit of their stamina and have since drifted off to sleep in each others arms. Or, at least one of them did. Ochako was sleeping peacefully with her arms wrapped around Izuku. Izuku, meanwhile, was wide awake staring at the ceiling, mind still reeling from everything that happened. His body was covered in lipstick marks, scratches, bites, and hickeys, a visual sign for just how intense the sex was.

But while it was probably the best sex with Ochako he's had in awhile, something about it felt... strange. Apart from how unusually aggressive she was, Ochako knew all the different ways to turn him on during sex, almost as if she could read his mind. But that would be crazy, right? Last he checked, she didn't have a mind-reading Quirk. As he laid in bed, his mind was still racing. "So I've learned three things about my girlfriend." he thought to himself. "One, Zero-G sex is really fucking hot. Two, Ochako has far more stamina than I thought. And three... she's downright feral when she's horny."

"You got that right." Ochako suddenly spoke up, startling Izuku. "And number four, she has apparently found a way to read minds." he thought "Oh God, that's not terrifying at all." Izuku turned over and tried to go to sleep while Ochako laid there with a knowing smirk on her face.


The next day, at Mei's workshop...

Mei was at her workshop tinkering with her newest invention when Ochako arrived with the mind-reading headphones in hand. "Well if it isn't the Gravity Girl." Mei greeted. "Just who I wanted to see. So, how did my baby do last night?"

"Oh it worked." Ochako replied. "Far better than I thought. In fact, I was wondering... think you can make one specifically for me?"

"Well, once I've worked out the kinks on this one and give it to Mandalay, I think I can make one for you with enough time." Mei replied. "Though can I ask why?"

That caused Ochako to look away with a noticeable blush on her face, nervously rubbing her arm. "Without going into too many details, let's just say I found a more... creative use for it." she then thought to herself. "Turns out reading your boyfriend's mind during sex and finding out differentways to turn him on makes sex hotter. Who knew?"

The End!


Part of me really wanted to go full smut with this, but I thought it'd be better to leave the sex up to the reader's imagination. Well, so ends my tale! Till next time!
