Work Text:
It had been a few weeks since Izuku Midoriya started interning under the Number 5 Hero, Rumi Usagiyama (aka Mirko). It was All Might who suggested the idea. After Izuku developed his Shoot Style and unlocked his new Blackwhip and Danger Sense Quirks, All Might felt that Mirko would be the best hero to intern under due to their similar, kick-focused fighting styles. And so, he reached out to Mirko to ask if she'd let Izuku intern under her. While initially reluctant due to her lone wolf personality (or lone rabbit, in this case), she changed her mind after remembering his performance at the Sports Festival and his takedown of the villain Overhaul. So she agreed to take him under her wing.
To Izuku's surprise, however, he wouldn't be interning alone. His partner for this internship was a girl from Shiketsu High named Kefla Kurogane, hero name: Saiyan Princess. Kefla was a muscular girl of average height. She had black, spiky hair with bangs framing both sides of her face while the majority of it was held up in a ponytail. Her Hero costume consisted of a purple belly shirt with form-fitting purple pants, golden armbands on her wrists, green earrings, and black and gold boots. Her most notable feature was the simian tail that protruded from behind her. Kefla’s Quirk, Zenkai, allowed her to convert her life force into energy that grants her superhuman strength, speed, endurance, and flight. She can also project this energy in the form of destructive blasts and can even mold this energy into shapes such as barriers for defense or large hands and claws for offense. In many ways, her Quirk was similar to One For All. Because of her powerful Quirk, she was considered to be Shiketsu's top student.
Izuku's first meeting with Kefla went rather… poorly. Like everyone else he met, Kefla didn't think much of Izuku at first, dismissing him as a nerd. But he soon got the chance to prove her wrong when Mirko set up a sparring match between the two to test their skills. And what a match it was! Kefla truly lived up to her reputation as Shiketsu's top student. Even with Izuku using 45% of One For All's power, Kefla gave him one hell of a fight. She truly lived up to her reputation as Shiketsu's top student. Of course, Izuku gave as good as he got. He managed to win the match, if only by the skin of his teeth. And in doing so, he seemed to have won Kefla's respect in the process as since their match, she started treating him differently, being a bit kinder to him. If only a little bit.
As the two spent time together, Izuku began to learn more about Kefla. If one were to sum up her personality in a few words, the words “Wild Child” would definitely come to mind. In many respects, Izuku found Kefla's personality very similar to Katsuki's. Like Katsuki, she was loud, brash, competitive, confident, always ready to speak her mind, and always strove to be the best. She was also a bit of an adrenaline junkie, freely admitting that part of the reason she wants to be a hero is her love for adventure. This unfortunately made her quite reckless. More than once, both Izuku and Mirko had to come to her rescue when she ended up biting off more than she could chew during missions. And much like how Katsuki and Izuku idolized All Might from a young age, Kefla was a huge fan of the Rabbit Hero Mirko, which is why she chose to intern under her. It was easy to see why. She and Mirko were so similar in personality that Shoto would likely think Kefla was Mirko's secret love child.
But as Izuku got to know Kefla, he soon discovered… another side of her: She was quite the shameless flirt. When patrolling the city, Kefla would sometimes flirt with any boys that approached. Of course, this had its limits. During one patrol, a drunken civilian made the mistake of groping Kefla's breasts. Poor bastard got thrown into a dumpster for his trouble. Though she flirted with many boys, Izuku was her favorite target as she seemed to relish finding ways to make him blush. Whenever the two sparred, she always had a suggestive comment ready to trip him up and cost him the match. Of course, Izuku made himself an easy target. Though his time at U.A. had done wonders for Izuku's confidence, he has never been good around girls. Back during his Aldera days, girls never paid the "Quirkless Loser" a second thought. So naturally, he had no way to respond to a girl flirting with him.
Today, Izuku, Kefla, and Mirko were working out at a local gym owned by Mirko. After a round of vigorous exercise, Izuku headed to the showers. Months of vigorous training granted Izuku the physique of Adonis. The numerous scars that littered his body, permanent reminders of both the toll his Quirk took on him and the intense battles he survived, only added a rugged look to him. He gave a happy sigh as he scrubbed his curly green locks with that special shampoo Mina recommended, but a downside of this overly soapy cleanser was he couldn’t see, or really hear anything as it covered his eyes and ears along with his bountiful locks. He rinsed his head under the water, letting it all cascade down his body and into the drain, For the most part, Izuku thought he was alone in the showers, Danger Sense not making a sound...
...And that's when he felt it.
He only had a moment to hear the light patter of footsteps on wet tile before he felt a hand firmly grip his ass. A high-pitched yipe escaped his lips and on instinct he turned to deliver a roundhouse kick to his potential attacker... only to find himself face-to-face with a fully-naked Kefla, who had blocked the kick with her hand. Her toned, Amazonian frame was on full display for Izuku. Her hair, normally tied in her trademark ponytail, was now unbound, looking as wild and unruly as her personality. "Nice reflexes, Small Might," she teased, using her nickname for him. A mischievous smirk danced on her lips.
Izuku gave a sigh of relief, taking a moment to calm himself as he lowered his leg. "Hey, Kefla," he said as he went back to showering. It took about five to ten seconds for his brain to catch up. Once it did, his emerald eyes widened as he quickly realized there was something very, very, very wrong with this scenario: There's a naked woman in the shower with him!
"KEFLA?!" Izuku shouted as he turned to face her again, nearly slipping on the wet tile floor from how fast he turned, though he managed to catch himself by placing his hands on the wall. "W-w-what are you doing here?!" Realizing that his manhood was… exposed, he immediately moved to cover himself. Though he couldn’t completely cover that package of his, letting Kefla get sneak peeks on the slowly rising boner he was trying to suppress.
Kefla, meanwhile, just stood there with an amused smile on her face as she watched Izuku's predictable but oh-so adorable reaction. No matter how many times it happened, it was always fun to see him freak out like this. "What's wrong, Small Might? Not used to seeing a naked girl?" She teased, folding her arms across her chest and under her breasts. He was naïve if he thought she didn't see that throbbing rod between his legs. That only made her smirk grow. They hadn't even started and he was already getting horny. Let's see how far she could push it. "I came in here to take a shower," she began. "But then I saw you were alone, so I figured you could use some company." She moved closer to him and placed a hand on the wall next to Izuku, cornering him like a predator cornering fresh prey.
"You know..." Kefla began. "This place is a bit boring. Maybe we can spice things up with a more... different sort of workout."
"A d-d-different w-workout?" Izuku stammered. "W-What do you mean?"
Kefla chuckled. Izuku really could be dense sometimes. "You're cute when you try to play dumb," she said. "But I think you know exactly what I mean. I'll give you a hint: It involves me, you... and your dick." Izuku didn't respond, but stared at Kefla as a blush crept upon his cheeks. "What? Too subtle for you?" she asked. "Well, let me spell it out: You're cute, I'm bored, and I wanna fuck."
Izuku's eyes widened at the brazen statement, his nerves tingling and mind racing. The hand pinned to the wall beside his head might as well have been wrapped around his throat with how hard it was to breathe. Her large breasts bouncing inches from his face, and the seductive smile bearing down on him certainly didn't help matters. The blush that colored his cheeks now had spread across his entire face, which coupled with his green hair, resembled a Christmas decoration. His green eyes looked into her own with anxiety. The boy could crush giant robots and monsters with ease and go toe-to-toe with the most dangerous villains, but yet he was helpless against his greatest weakness... the flirtatious advances of an attractive female.
Eventually, after a round of silence, Izuku finally found his voice again. "Y-y-you mean you want to... have sex?!" he exclaimed. "B-B-But Kefla, this is a bit too sudden! I mean, sure. you're very attractive, and it's nice spending time with you, but this is too much too soon and-" It wasn't long before Midoriya dropped into his classic "mumbling phase", a habit he's had since his youth thanks to his hobby of analyzing the Quirks of Pro Heroes. Whenever he would overanalyze a situation, he would get so lost in his thoughts that he'd fail to realize he's voicing them out loud, usually creeping out his classmates. When they first met, Kefla found his habit annoying. But right now, it made him look even more adorable. Here's a boy with immense strength enough to probably bench press a bus, but throw a cute girl in his face and he's a stuttering, stammering mess. It was a comical paradox, really.
Kefla placed a finger on Izuku's lips to silence him. "Anyone ever tell you that you are way too high strung?" she asked. "You really need to learn to lighten up. And I think I can help with that."
"Kefla, we really shouldn't do this here," Izuku continued to protest. "We could get in so much trouble!"
Kefla responded by slowly and lustfully dragging her tongue along his neck. "Danger's half of the allure, Small Might," she teased, clearly uncaring if someone walked in on them. For her, that would just be more of a turn on. Kefla was quite the thrill seeker, after all. Taking risks like this was always exciting. "Besides, your mouth is saying no..." Izuku let out another yelp as he felt something constrict around his cock. He looked down to see Kefla's pherensitle tail coiled around his erect dick like a serpent coiled around its prey. "...But Little Dicku here is saying yes."
Izuku felt his face flush with embarrassment. Kefla, meanwhile, began stroking his cock with her tail in an attempt to arouse him. “What's wrong, Small Might? Cat got your tongue?” she teased as she wrapped her arms around his neck, pressing her breasts against his chest as she leaned in to whisper in his ear.
“Don't you think you should stop pretending?” she began. “I’ve seen the way you look at me during missions and the way you were staring at me while I was working out. Admit it, you’ve been wanting to fuck me for a good while, huh? Well, I’m giving you what you want. After all, we're both alone and you probably won't have another chance to fuck a hottie like me, so why not live in the moment?”
Izuku fell silent as he pondered on her words. He wanted to refute her words, to deny them. But the longer she spoke, the harder it was to deny the truth in her words. Since they started interning together, Izuku had begun to feel a growing attraction to her. Her brash, confident, never-say-die attitude reminded her so much of Katsuki, her Quirk was amazing, she was a powerful fighter, and she was admittedly... very pretty. Provisional Hero he may be, but Izuku was still a growing boy. And when a girl like Kefla offers you a good time... well, what boy in their right mind would possibly say no?
Besides, It was obvious she wasn't taking no for an answer and Izuku clearly wasn't going to try and be bold enough to say no. Regardless, his body was begging for more anyway. Still fully hard, Izuku groaned and shuddered in response as she stroked him. "I... I've never... done something like this before," he whined, opening one eye to look at her.
Kefla merely chuckled. "So I caught me a virgin?" she teased. "This just keeps getting better." She then gripped the sides of his face and forced him to lock eyes with her. "Well, just sit back and relax, Little Man. I'll make your first time something to remember." Before Izuku could get a word in edgewise, Kefla slammed their lips together in a fiery kiss, her tongue invading the greenette's mouth as she pushed him against the wall.
Izuku's eyes widened to his hairline as he felt her soft lips mashed against his, her tongue wrestling against his own as she swapped spit with him. Those nervous whimpers he kept making grew louder. The poor boy was practically trembling in her hold yet despite his hesitancy and worry about getting caught, Kefla would feel his hips pushing back into each stroke of her tail. "Mmhh!" He whimpered between the kissing, arms moving to wrap around her waist. Each stroke of her tail right down to the base of his shaft had him jump as pleasure shot through him. Even though he wouldn't admit it, this was the best feeling he'd ever experienced yet.
And Kefla could tell how much Izuku was enjoying this. The way his hips bucked against him, the way he was holding on to her. pushing against her chest. He could deny it all he liked, but deep down he wanted this just as much as she did. She eventually broke the kiss, leaving Izuku gasping for air. She once again dragged her tongue along his neck before leaning in to whisper in his ear. "Seems you're enjoying this a lot more than you want to admit," she teased, nibbling on his ear as her tail continued stroking his dick. "We haven't even started and you're already nice and hard. You poor thing. I bet you've been pent up all day, huh? Don't worry, though, you're in good hands. Just relax and let me take some of that pressure off of you."
Before Izuku could reply, Kefla was already trailing kisses and licks down his chest as she got to her knees, bringing her eye-level to his cock. She licked the head of his cock a few times before she slowly took it in her mouth. Izuku moaned as he felt Kefla's lips seal around his tip and sink towards the base of his shaft. A shudder ran down his spine as she kept moving forward, ever so slowly teasing him. His pole pulsed and dribbled some pre-cum in her lips, a tangy sticky flavor for her to savor as his hand gently brushed through her hair, softly encouraging her on. His other hand pressing palm to cold tile to keep his balance.
Kefla began to suck Izuku off at a slow rhythmic pace. She could feel the pre-cum dripping into her mouth, its taste sweet on her tongue. It, along with the hand running through her hair, only served to spur her on further. In response, her strong yet slender hands reached behind Izuku to grab at that toned ass of his, giving it an occasional squeeze. Her tail, meanwhile, reached out and began to massage his balls for good measure.
Izuku's spine shuddered with her slow and deliberate motions. Her hands groping his ass, the gentle feel of her tail rubbing against his balls only added to his building pleasure. God, had she been practicing for this? Just the sensation of Kefla giving him a blowjob was making him feel incredible. Light flickers of green, sparking energy emanated from his body, ever so briefly. She might not have realized it, but she was doing quite a lot for him, considering he'd never gotten more than as much as a kiss on the cheek from a girl. The way her fingers slowly squeezed his tight buns, digging into the scarred flesh and tight muscles. He trembled in ecstasy, a quick peek down to see her eyes looking back up at him with that cock down her throat made his cock jump, another thick splurt of precum as he was teetering the edge of losing control.
The second taste of pre-cum caused Kefla to abruptly stop what she was doing for a moment. "Feeling good, huh?" she asked. "Well, it's only going to get better from here." With that, she wrapped her breasts around his cock and began sliding them up and down as she resumed sucking him off, this time at a much faster pace. Her tail continued to play with his balls.
Izuku gasped and cried out as pleasure overwhelmed his senses, the combined assault of Kefla's mouth, breasts, and tail had him panting and squirming around, trapped between Kefla and the wall still. "K-Kefla! I- I don't know how much more I can take!" He whimpered. Green sparks flickered along his body as she edged him closer to climax, making him grasp at her head as her lips sealed around his girth and her head bobbed back and forth. The feel of his hand in her hair only served to encourage Kefla as she continued her ministrations, eager to bring the boy to his very first orgasm.
And Kefla wouldn't have to wait long as her efforts were too much for Izuku to resist any longer. His cock was overwhelmed, his senses cranked to the max as his balls clenched and butt tightened, his grip pulling her lips to his base as he arced with crackling power of One For All. Moments later, the young teen gave in, crying out and practically exploding thick ropes of cum in Kefla's mouth as well as some excess getting all over her chin, his knees shaking as she gave him his first mind-blowing orgasm.
Kefla's eyes widened as Izuku finally hit his climax. She knew that Izuku was backed up, but she was clearly unprepared for the amount of cum that would erupt from him. She tried her best to swallow as much of the cum as she could lest she choke. Eventually, however, she managed to pull away and let some of it spill on her face and breasts. She took a few deep breaths to recover. "Jesus, kid." She said between breaths. "I figured you were backed up, but holy fuck, I wasn't expecting the whole damn fire hydrant! So, how do you feel?"
Izuku didn't immediately respond. He wobbled a bit on his feet, panting and leaning back against the wall as he wished for his head to stop spinning. His cock hung at half mast, dripping what leftovers still clogged his pipe down to the floor. "It.. it was uh.. crazy." He whispered, still trembling a little, having for the moment forgotten all about the risk of being caught as he came down from his climax. "I’m sorry I grabbed you like that! I should have asked before I acted! M-My Quirk tends to boost my uh… performance. I-I should have warned you beforehand. I hope you’re not too upset!” Green eyes looked over her naked body, with ropes of cum dripping from her around her mouth and coating her tits, the sight of his partner on their knees with cum over her breasts made his recovery near instantaneous, his cock roaring to life again with throbbing pulsing power.
"Mad? Hell no. If I knew that, I would've fucked you sooner." Kefla teased as she stood up and wiped the cum off her face and tits. Izuku couldn't help but cringe at the blunt statement. The sight of Izuku's cock growing hard again made her smirk. "And it looks like you're still raring to go." She walked closer to Izuku and put her hands on his shoulders. "Now then, I made you feel good. So I think it's only fair you return the favor." Before Izuku could get one word in, Kefla used her immense strength to push the boy down on his knees, putting him eye-level with her pussy, which was decorated with a neat little bush of pubic hair.
"Well? You gonna stare at it all day, or are you gonna give it a lick?" she asked, her voice a bit more commanding. Now faced with the sight of her pussy just inches away from his face, Izuku began to feel incredibly nervous once more. After a few moments to steel his nerves, the young hero finally made the dive and leaned forward, tongue flicking out and amateurishly dragging up against her folds. "L-Like this..?" He asked, doing a mediocre job so far as he let the broad flat surface of his tongue repeatedly lap up against her pussy.
Kefla let out a small, breathy moan when she felt Izuku's tongue brush against her folds. "Not bad, Small Might." she said, running her hand through his hair as a sign of her approval. "For a virgin, you're a fast learner. Now keep licking."
At the feeling of her fingers running through his messy mane of green-black hair, Izuku shuddered, spurred to put more enthusiasm in his actions. His tongue pushed up, parting her folds and dipping inside of her briefly. The taste and smell were so strong, but the boy was surprised to find it was from off-putting. He would have tried to thank her for the light praise, but he was too focused on giving Kefla what she wanted. "T-Thanks," he mumbled eventually, his lips and chin gradually getting coated in her arousal as he dutifully lapped, licked and tended to the woman still holding his head. He couldn't believe the situation had devolved into this, even more so that it felt like he was actually enjoying it all, deep down.
More moans escaped Kefla's lips as Izuku ate her out. Her hand gripped his hair tighter in approval while the other hand reached up to cup her breast. Kefla then decided to return the favor by having her tail reach down and coil itself around his cock, gently stroking him off once again. "That's it, Small Might," she moaned. "Work that tongue. Make me cream."
Kefla's clear approval of his servicing helped stoke him to do just as she asked, working his jaw and tongue to 'fuck' her soaked pussy as best as he could manage. As sore as his mouth was getting he didn't dare let up, especially as he felt her tail wrap around his dick and stroke from base to tip. "Aa-aah... yefh ma'ahm.." Izuku moaned out, forcing his tongue as deep as possible inside of her, his face growing gradually more and more coated in her arousal as he pleased her, both hands moving to grasp the back of her thighs and grip tight.
As Izuku's tongue plunged deeper into her folds, Kefla's moans rose higher in volume as she neared her orgasm. Eventually, she hit her peak and came with a loud scream, her pussy spraying Izuku's face with her essence as she tightly gripped his head to hold him in place, forcing him to drink her juices. Eventually, she let go of Izuku's hair and took a step back as she rode the high of her orgasm. "Not bad." she said. "You really know how to use that tongue."
The compliment had Izuku blushing up a storm, still unable to believe that he had just eaten a girl out. “Um… thanks, I guess,” he sheepishly replied, rubbing the back of his head.
"Well then, I think it's time for the main event, don't you?” Kefla asked.
“Main… event?” Izuku asked. He watched as Kefla suddenly balanced herself on her tail, spreading her legs wide and giving Izuku a clear view of her pussy. The sight of it caused Izuku's erection to rise to full mast. Kefla smirked at the sight of his erect cock and made a teasing “Come get me” gesture with her finger.
That made Izuku's emerald eyes widen in shock. “You… You mean…?”
“What, you want a written invitation?” she asked with a mildly annoyed expression. “Stick it in, already!” Izuku audibly gulped as he approached Kefla, eyes transfixed on her pussy. Once close enough, he pressed the head of his cock against her folds. “Are you sure…?”
"C'mon, you can't wuss out on me now," Kefla said, rolling her eyes. "We've come this far. Might as well go all in. Besides, you're not the first person to pop this cherry." Kefla had many sexual encounters in Shiketsu. What can she say? School can be stressful sometimes, and sex was a way for her to de-stress (exercise being another way). Of course, she wasn't some slut who spread her legs for the first cock she saw. She had standards, after all.
Seeing that there was no way out of this, Izuku slowly inserted his cock inside Kefla, taking care not to hurt her. Kefla grunted as she felt his member slowly enter her. "Damn, kid, you're even bigger than I thought." she said. Izuku couldn't help but smile at the compliment. Taking a few moments to adjust to the feel of being inside her, Izuku began thrusting in and out of her pussy. His pace was slow and rhythmic, as if he was trying to ease himself into what he was doing.
Kefla, meanwhile, was not amused. She stared at Izuku with a rather unimpressed expression. "Small Might..." she began, her voice flat. "I know you can do better than this."
"Should I go faster?" Izuku asked. Kefla placed a finger under her chin as she paused to think. Her expression then brightened as her lips curled into a devious smirk. "Well... you did say that Quirk of yours boosts your performance."
Izuku's eyes widened at the statement, knowing full well what she meant. "Kefla, no!" he protested. "You don't know what you're asking."
"Oh I know exactly what I'm asking." Kefla replied, licking her lips.
"Kefla, I have never used my Quirk like that before," Izuku said. "I have no guarantee I can control it. What if I seriously hurt you?"
"C'mon, Small Might," Kefla replied. "I'm not made of glass. You've seen me get knocked around enough to know how tough I am. Besides, I wouldn't be asking if I didn't trust you. Now put your back into it and give me a Plus Ultra fucking!"
Izuku sighed. "Just remember, you asked for this," he muttered under his breath. Izuku closed his eyes to concentrate and red lines soon appeared on his body as it sparked with green lightning. Pressing the head of his cock against her pussy, he rammed it inside her with one swift thrust, the force of it knocking the wind out of Kefla's lungs. "Oh, shit!" she gasped. "Now that's what I'm talking about!"
Spurred on by her praise, Izuku firmly grabbed on to her hips as he began thrusting into her. Unlike earlier, his thrusts were faster and much more forceful. And Kefla was certainly enjoying herself this time. Her moans of pleasure echoed throughout the room as she wrapped her arms around Izuku's neck. 'That's it, Small Might," she moaned. "Show me what you got! Fuck me like you mean it, hero!" Izuku obliged and continued thrusting into her. As he did, however, he began to unconsciously tap into more of One For All's power. He started at five percent, then jumped to eight percent, and he was now at thirty percent. And the more he tapped into One For All's power, the faster his thrusts became.
The wet sounds of skin hitting skin echoed through the room, mixed with the moans of wanton pleasure from both Kefla and Izuku as the latter pounded away at her pussy like a man possessed. Izuku felt his cock beginning to swell, the sign of an impending orgasm. "Kefla...! I'm about to...!" Before he could finish, Kefla crashed their lips together in another hungry kiss, their tongues dancing in each others' mouths as she wrapped her legs around him. "Don't you dare pull out on me!" she said. "I wanna feel that thick load!"'
Kefla would soon get her wish as with one final thrust, Izuku finally came, his cock exploding in a fountain of cum that filled Kefla to the brim. Simultaneously, Kefla reached her own orgasm, letting out a loud scream as she came all over Izuku's cock, drenching it with her essence. As the two rode the high their shared orgasm, Izuku felt his legs start to buckle as he stumbled back and leaned against the wall, sliding down with his cock still lodged in Kefla's pussy. Kefla, meanwhile, was drenched in sweat as she climbed down from her orgasm.
"Fuck, Small Might," She said in between breaths. "Always knew there was a wild animal in you. Just needed a push to help free the beast. So... was it as fun for you as it was for me?"
"So... tired..." Izuku said, still recovering from the orgasm. Kefla chuckled and slowly licked Izuku's cheek. "That was quite the workout," She said as got off of Izuku and stood up, cum leaking from her pussy. She walked out of the shower, grabbing a nearby towel and draping it across her neck. "By the by," she said as she turned to face Izuku. "You ever want to do this again, I'm always available." With a wink, she turned and walked out the room, leaving Izuku alone.
Izuku merely sat against the wall, too exhausted to move. His mind was still reeling from everything that happened. Somehow a simple shower ended with him having sex with a girl for the first time in his life and losing his virginity. He still couldn't believe what just happened. But despite everything, there was one thought on his mind...
...He really was looking forward to another workout session.
The End!
