Chapter Text
Izuku adjusted the metal bracing around his collar, settling it as he looked at the two girls before him. “You guys sure about all of this? I mean I bet it’ll be an educational experience but…” He didn’t want to say outright there was little chance they could beat him, but it was true.
“What? Wimping out on us now?! No way no how, you’re in it for the long haul buster!” Setsuna grinned at him, her sharp teeth on display as she rested her hands on her hips. “Get ready, cuz me and Yanagi are going to beat the shit out of you, and cash in on that reward~” She grinned lecherously at Izuku. “I’m gunna treat you reaaal good~ hehe.” Izuku blushed, inching away from the girl’s hands, groping the air in front of him.
“Tis necessary that to experience an amelioration of our ability, we must challenge those that transcend our own essence,” Yanagi spoke, clad in her white Kimono and black mask, her hands held in front of her like a spirit and her back hunched. “The stakes ensure you do not pity us.”
“And cuz mama wants a strong boy toy!” Sestuna giggled, circling around Izuku like a shark, staring him up and down.
He wouldn’t ever say it out loud, but part of him wanted to lose just to see what the hell she would actually have him do. Yanagi as well, he couldn’t see her being quite as much of a perv, but she had still agreed to participate in something like this. “Still, a week is a long time.”
The two had asked him to face them both in a sparring match, the conditions being that the losing side would be the winning side's servant(s) for a week. He was pretty surprised when they came to him of all people but with the defeat of the League being largely attributed to his contributions, he supposed something of a gap between him and most other students had formed.
His hand came up to rub at the back of his neck, feeling his own calloused fingers brush up against a scar. “I mean, I don’t really know what I’ll do if I win, isn’t it better just to do this without stakes?”
Setsuna shook her head, long wild hair swinging side to side. “Nu-uh! You agreed, no backing out now! It’s a two-on-one, so don’t be too confident.” The girl turned her back to Yanagi, leaning against the ghostly girl and shooting two finger guns his way. Yangi, though there was no light in her eyes, did the same. Four finger guns now pointing towards him. “We’re the dino-ghost combo! And I assure you we’ll be a crustaceous level of trouble!”
“I… don’t doubt that.” He let out a small exhale, glancing around the fake city that constituted a U.A. gym. “Well, do you guys want some prep time at least?”
Setsuna spoke, picking herself off Yanagi’s back. “Na! We can go now, its n-” She was cut off as a strand of Blackwhip wrapped around her neck like a python, causing her to jolt and provoking a small noise of surprise.
Izuku’s finger pointing towards her in a finger gun of his own, darkwhip shooting out of it. He smiled gently at her. “You two should use the prep time. I’ll give you five minutes.” He withdrew the strand, sliding more slowly away as it unwrapped from her neck.
Setsuna’s face was flushed and stammered out. “J-Just you wait!” Before grabbing Yanagi under her armpits and floating both of them up and away.
“Was that too mean?” He looked up at Setsuna, accidentally taking a solid look at her ass. Her skintight uniform hugged the bubbly fat close enough that he could see it wobble as she floated away. “....Na, she deserved that one.”
Floating up away from him, Setsuna looked down at Yanagi, who was hanging limply from her arms like a corpse. Setsuna let out a shuddering sigh. “Fuck that was way too hot. I’m going to be soaked this whole fight.”
“Indubitably. I’m jealous.”
“Indubitably, you’re so funky.” She floated the two of them down on a rooftop a few streets away from where all of them had walked in. The two girls both leaned down, huddled together despite how empty the streets were. “Alright, what's the game plan?”
“I believe you’re better at planning than I am.”
“No I mean like, when we make him our servant. Who gets first dibs?”
“Placing the cart before the horse. Let's focus on defeating the future number one.”
Setsuna grinned. “Whatever. I’ll run point, keep him distracted and unfocused. As long as I keep all my limbs in different spots it’ll be hard for even him to drop me. You run interference and annoy him. I’ll defend you if he goes after you. Sound good?”
“It’s acceptable.”
“Now c’mon, we’ve got lewd things to get out of the future number one~”
There was a massive bang, as a shot of pure force displaced air and caused it to rush back into the gap, creating a sound like thunder as a visible wave of displacement shot into the air. It caused both girls to flinch at the sheer power behind it, easily enough to topple buildings. “Five! I’m coming now!”
Setsuna smirked, speaking under her breath. “Oh you’ll come alright. You’ll come hard. Let's go Yanagi, we’ve got some hard coming of our own to do.”
“You’re enjoying yourself too much.”
There was another loud bang, this time accompanied by a flashing green thing in the middle of it, the motion causing the image to blur into just a spot of color. The blurring stopped as it reached the apex, revealing it as rather obviously Izuku, his eyes locked onto the two of them.
His outstretched hand shot tendrils of black energy, wrapping around the tops of nearby buildings before the tense tendrils yanked him towards them.
Yanagi turned and started running. She reached into the back of her outfit and pulled out a sturdy board, tossing it into the air. Her quirk took control over it as she hopped on. Shooting through the air to create some distance.
Izuku moved to intercept but was met with an arm flying up at him. He cocked his head back, ducking under it. He twisted, slamming into the ground with another loud bang, Setsuna reforming her body on the roof of the closest building. She turned around and smacked her own ass. “Gotta come quicker than that!”
Izuku felt danger sense go off, and shot his arm out, batting aside a dumpster that had been thrown his way. He saw Yanagi up on the opposite building, hovering on her support equipment. “Do watch your language in the future, she's going to be making jokes like this for a while.”
The dumpster picked itself back up, twisting in the air as she lifted a hand in an accompanying movement.
Izuku tilted his head side to side, hand coming up to apply enough pressure to get a solid popping noise. “Alright. Let's do this.” Green lightning bolts crackled around him, as he positioned himself towards Setsuna, crouching low and ready to burst off the ground.
He took a step forwards, and leaped backward, twisting in the air to face Yanagi instead. The dumpster lifted up quickly, rushing towards him from below. He flicked it away, sending it slamming back to the ground.
Yanagi’s eyes widened. That was easily in the hundreds of pounds. Seeing him charge up another flick, she jumped off of her board, landing on the roof. He turned to use the flick to push himself through the air, crashing down in front of her, several tendrils of black whip shooting out towards her.
She swiped out with one hand, her floating board slamming aside the first of the black tendrils, before she used her other hand to reach into her kimono. She withdrew three throwing stars, flinging them out as they took on her blue color.
Blackwhip surrounded Yanagi’s board, yanking it out of her psychic grip and using it to bat each throwing star to the floor.
Setsuna’s arms slammed into his back, and he didn't react. Adjusting her strategy, her dismembered arms wrapped around his neck in a chokehold. He didn’t react, just walking towards Yanagi.
The ghostly girl was backing up, getting walked down by him. He was starting to feel a little bad, considering how hard they both seemed to be trying. His eyes keeping a close watch on Yanagi’s hands, even as she seemingly walked backwards without any kind of-
His eyes widened, danger sense going off as he had to use his quirk to jump high up into the air. The throwing stars that had been on the ground chasing his legs, trying to dig into them. She never lost control over them, just waiting for him to get close enough that she could shoot the metal through them.
He was a little curious how far she would’ve taken that. Blackwhip shot out again, the frustration from almost falling for it making the inky tentacles that much thicker and stronger.
On the ground the girl was rubbing her thumbs against her pointer and middle finger, the movement somehow coordinated with the metal pieces, as they started to spin faster and faster. Destroying any tendrils which tried to cling onto them.
Setsuna’s arm wasn’t really strong enough to cut off his circulation as long as he kept a small percentage of OFA running through him, but it was starting to get annoying.
He used his tendrils to attach to another rooftop, shooting down and switching targets as he avoided the spinning blades.
Looking right at Yanagi, he stuck his hand out, and flicked, the force overwhelming in an instant. Her throwing stars got thrown from her grip instantly, her control broken by a stronger force. The impact sent her tumbling backward, rolling over herself on the rooftop as all the air left her lungs. She was left face down, groaning as all the strength seemed shot out of her body.
“Would you quit ignoring me!”
Setsuna’s head popped up in front of him, no doubt trying to run interference so Yanagi could get back up.
“You’ve yet to do something worth acknowledging.” Ah, there it was. He was in his ‘hero mode’ where he would lose the nervousness, lose the anxiety, and just speak what he thought needed to be said. The look in his eyes was deadly serious, and Yangi couldn’t help a surge of arousal, even as she was put on her ass by him.
If she was honest with herself, that was probably part of the reason. She craved fear, and part of that in a relationship was appealing to her. She was pretty strong, so a man who could so easily take her down inspired a sort of enthralling fear inside her heart, which quickly turned to arousal. Or perhaps it didn’t even turn, and the two emotions were just one and the same for her. Hard to tell.
She tried to get up, managing a knee, before a strand of black whip shot out past Setsuna, wrapping around her ankle before she could react, and dragging her in towards him fast. That was something straight out of a horror movie. She was glad the mask was hiding the excited grin on her face, even as the back of her head hit down awkwardly on the concrete. It hurt, but she knew she was fine, so it really only added to her excitement.
Setsuna tried to advance at that moment, her feet slamming into his sides, while she reformed a full arm to cock it back and shove it into his chest. He still didn’t react to it, and once he caught on to where her head was, another strand of Blackwhip shot out, wrapping around her face and covering her mouth and nose.
Her hands shot over to try and pry it off, fingernails scraping against the tendrils of dark energy. The energy wrapped around his forearm, and he yanked it backwards, tugging her head towards him, before catching it. His large scarred hand palmed it like a basketball, keeping the blackwhip around her mouth and nose, preventing her from breathing.
Yanagi tried to scramble away, in part because that’s what a horror movie girl would do, and she was now firmly in character, and in part because it was genuinely the best move. He placed his knee on her back and put his weight down, forcing her flat against the floor. She let out a grunt, as his muscular arm wrapped under her head, clenching her neck between his bicep and forearm. He squeezed down, and she felt the force constrict her throat, preventing her from breathing as well.
Both girls clawed at his arms and hands, managing at best to leave scratches on him, as he took his time and choked the two of them out.
Setsuna’s limbs thumped against him, hitting him with all the force they could, and producing zero results, his body too hardened by his quirk to allow her any damage.
After a minute, her body went limp.
Midoriya just scoffed, not loosening his grip on her. “C’mon. You’re not unconscious, yet.”
Vision blackening and consciousness threading to slip, Yanagi felt her power tug out and grab his metal brace, flicking it up to hit against his face.
She was rewarded with more pressure on her back, her breasts uncomfortably pressed into the concrete as she let out a gagged gasp. “Clever. But I can knock down buildings, remember? Going to take a little more than that.”
She very much did remember, and the sentence and lingering feel of arousal at being manhandled so effectively was the last thing she remembered before the fuzzy blackness at the edges of her vision took over.
_____________________________________
Yanagi came back too with a start. Sitting straight up as her hand went to her throat, feeling the freedom of her breath as she took calming inhales.
“Hey there.”
She looked up, realizing the soft thing she had been sitting on had been Izuku’s lap. She felt herself blush, then slapped a hand over her mouth as she realized her mask was off. “Sorry sorry, wanted to make sure it wasn’t messing with you catching your breath.” Izuku handed it right to her. “For the record though, your lips are very pretty, I don’t think you should have to hide them.”
She cleared her throat as she slipped it back onto her face, though her pale cheeks got some colour with the redness that overtook it. “Tis a sallow and pale visage I wear. The void of the mask appeals much greater to me.”
He smiled at her, a soft and gentle thing. “Well, I suppose tis a sallow and pale visage I find attractive.” He laughed softly. “Can I ask actually, what were you intending to do with me?” He reached down, leading Yanagi to follow his movement and see that Setsuna’s still detached head was likewise on his lap, her mouth wide open as she snored softly. “She…uh, was probably teasing me right?”
“She was not. Her vocabulary is at its most immense when she speaks of you. And as her friend, I have borne witness to many depraved fantasies.”
“Is…Is it like a romantic affection? Or just, pure lust?”
Yanagi had to think for a long moment. “The lines are blurred.”
He let out a small, “huh,” as his hand went down and threaded through her hair, seemingly massaging her scalp. “She’s quite something huh? But, anyways, back to my first point, what were you going to do with me? Or too me I suppose.”
Her mask hid most of her face but she could feel the heat of her own flush. “...is that knowledge an order of yours?”
“I guess I can order you now can’t I?”
“Yes. You’ve earned that right.”
“Mhm.” He let out a small hum as he stared at her. “I’ll wait then. Until you want to tell me. Just let me say, that there isn’t much you could ask me that I wouldn't be willing to do.”
“You honor your servant.”
An amused noise left him as she referred to herself like that. “My servant for a week.” He leaned back, his palms flattening on the concrete roof where he had taken both of them to rest. Setsuna’s head was still in his lap, close enough to a certain place that Yanagi was certain she’d be quite excited to be told about all of this. “I’m probably not going to actually ask you guys to do anything you know?”
Yangai shifted in place, trying to figure out how exactly to phrase what she wanted to say. Her eyes drifted to Setsuna. “I think…Setsuna would greatly desire you to order her around. It’s difficult for me to ascertain if this challenge was pure arrogance or not, however, I do also believe that she was happy with either outcome.”
His calloused hand threaded through Setsuna’s hair as he was effectively just petting her. His eyes gazing down at her still sleeping form. “I feel like I’m struggling to restrain myself here. I mean, the right thing to do is probably just to let you both off the hook right? But two very pretty girls are both continuing to egg me on more and more.”
“Why not think of it as an issue of consent? We’ve both given it. Why is acting on your desire wrong?”
He hummed, glancing down at the girl. “Because there are a lot of different little intricacies there. I’m not sure blanket and total consent is a real thing. Especially not when it comes to…activities of this nature. I mean, what if one of you told me to stop? I obviously would, but then, kinda, disregards the whole fantasy right?”
Yanagi walked towards him, leaning down so that she could look at him dead on. “How depraved are you to worry about the two of us asking you to stop?”
He flushed red at her comment, some of that schoolboy anxiousness still there if someone was willing to dig. “W-Well I, it’s not that, like, I woul, you know, like, I-”
The ghostly girl adjusted from leaning to kneeling. Folding her legs together as she gracefully slid into position, as if she was about to serve him in a traditional tea ceremony.
“Do something to me.”
His face got more red. “H-Huh?”
She let out a small huff, which pushed her mask forwards on her face. “Do something to me. Anything you want. I give you express permission, and consent.”
“B-But like, what If I hurt you or something?”
“Are you going to punch me?”
“No!” he sounded scandalized at the very idea. Though given some of Setsuna’s…wilder days, that wouldn’t really be a deal breaker either Yanagi didn’t think.
She really worried about Setsuna sometimes.
“Then I think I will survive. Whatever desire speaks to your heart, act on it.” She felt her breathing get a little bit shaky. Anticipation flooded her body like a river, coursing through her body from her mind to her fingers, causing them to tremble a little.
The boy still hesitated for a second, before reaching out. Yanagi closed her eyes, fully expecting her breasts to be touched. Her eyes flew open, as a calloused hand touched her cheek.
Half of it was covered by her mask, but the boy was simply caressing her face. His own cheeks a similar shade of red to hers. “S-Sorry.”
Before he could pull away, she reached up to keep his hand there. “There was nothing that you should apologize for. Please. You can keep going.”
He opened his mouth for a few seconds, before closing it. His fingers moved back, towards her ear. One of his strong fingers hooked around the soft fabric of her mask, pulling it off of her ear. Gently removing it from her face.
Yanagi wasn’t embarrassed about her appearance to the point of any kind of complex. At least not in her mind. It was just that she looked better with a mask on. The hidden black void gave her an air of mystery, and the hidden mouth would keep people from seeing her somewhat too small lips.
All of the attention on her face now made red heat dash her cheeks once more. His hand returned to its position on her cheek. “Um…you really are pretty.”
She swallowed thickly, struggling to meet the earnestness in his eyes. As her own turned downwards. “Thank you.” Her confident and persuasive persona crumbled like a paper tiger.
Setsuna had probably wanted for them both to be naked by this point, but Yanagi was struggling to handle her face being caressed. She squirmed in place a little. But the two had flipped positions, as Izuku moved his hand lower, and his thumb brushed over her lips. Tilting her chin up to make sure she was looking right at him.
The feeling of the battle scared finger gave her a new appreciation for him. She had always seen the dim discolorations tattering his form, but it was another thing to feel them. To feel the marks, the sandpaper scratches that he only got from putting his body on the line for the sake of someone else. It was enthralling in a lot of ways to feel that touch. It felt like the scales of a snake wriggling up around her throat. Like the chainmail of armour protecting her. Like the rough hilt of a sword, and the scratched wood of a shield.
It was a lot to take in, especially as that thumb gave her lips another pass over. His eyes scanning hers for something. Some kind of reaction. She hesitated for just a second, before parting her lips. Taking a guess at what he wanted.
Arousal flashed behind his eyes like a lightning bolt striking a calm meadow. At the same time she registered what that sudden intensity was, a lighting bolt hit her as well. One of satisfaction and gratification. She was turning him on, and that made her happier than she would like to admit.
His thumb moved slowly, giving her time to close her lips. But she didn’t. Not until it pushed into her mouth. A new level of understanding of those scars, as the fingerprint of his thumb pressed down onto her tongue.
It felt…wierd. Somehow more intimate than a kiss. But with less ritual. No mention of eyes closing or opening, no worries about what to do with her mouth, no problems of timing or when to pull away or anything like that. It was just…Him exploring her.
She quite liked that.
He pulled his thumb out of her mouth, and she closed her lips. Feeling a little heated. Fingers lifted up her chin once more, before he lowered his head down. The two of their lips inches away from each other. Close enough that she could feel his breath when he spoke.
“You’re…sure I can do whatever I want?”
With his eyes darting down to her lips, it was clear what exactly that was in this moment. “I am here to satisfy your desires.”
“But, is that also what you want?”
“Very much so yes please do it.” It all came out in one rambled fumble, her own anticipation getting to her as she wanted the kiss. Her legs started to rub against each other on the ground.
He blinked at her for a second, before one of his cheeks puffed up in an attempt to restrain his laughter. He collected himself after just a moment, smiled at her, then leaned in.
It was soft, chaste, and gentle. Nothing intense or hard. A far cry from being choked out and manhandled just seconds ago. Still, there was a kind of adrenaline dump that happened right after. Or maybe the opposite. A crashing of heat, a flooding of feelings, a rupture of stable ground, and a pattering rain of temptations, choices, movements she could make. Most of which involved pushing deeper into him.
Instead, she managed to keep her cool. Breathe out heavily, and while looking him in his eyes ask through breathy exhales. “Is that all you desired?”
That flash of arousal was behind his eyes once more. “Not even close.”
A few moments of silence rang out, before the moment was suddenly interrupted by the sound of unzipping.
Yanaig had assumed it was something much different and flushed a deep, deep cherry red. Her eyes looked down at the concrete roof. “I-I supposed you’re able to demand that much.” Her voice was very quiet, enough that Izuku didn’t hear her. She reached for her Kimono, pulling one side down off of her shoulder.
Izuku was looking down to see Setsuna having woken up at some point. Her teeth around his zipper as she angled her head to pull it down. He grabbed her head and lifted her up, causing her to let go with a small. “Ah!”
“S-Setsuna!” He glanced past her at Yanagi, who’s bare shoulders were now on display.. Very quickly and very hastily wrapping them back around herself.
“Y-Yes. Setsuna. What on earth.” She pulled her fabric a little closer, covering her up more even though the image of her bare shoulders had been burned into Izuku’s mind already.
“What! I lost the battle to become your servant, wake up with my head against your crotch while you're popping a boner. I feel like I made a very reasonable connection there.”
Izuku just sighed. Throwing her head up in the air, and letting the girl catch herself, her head floating to where her body was. The form sitting up as the head slotted onto it, before standing, stretching, and inspecting her body. “Huh? Did you really not fuck me?”
Izuku held his head in his hands. “S-Set.”
Yanagi cleared her throat. “He is um…still working out how he feels about everything.”
She gave them both one of her characteristic smirks as she glanced between him, her, and his crotch. Making Izuku cover himself like a scandalized schoolgirl whose skirt got flipped. “No~ I think his body knows how it feels pretty good considering the thick hard thing that was rubbing against my cheek behind those pants.” She lifted an arm up high in the air, the other going behind her head to hold onto it as she stretched. “He’s just trying to make sure all his bases are cleared. And they are! Free reign! No limits! Go crazy!” She tapped her heart and her head. “These two are the only parts of me that need to be kept safe!”
Izuku shuddered. “I…distinctly dislike the implication there.”
She shrugged. “I figured as long as you knew I do have some limits you’d feel more free to go all out!”
He rubbed his eye with one hand. “I worry about you Set.”
She stuck her tongue out at him, before glancing around the arena. “Well, the challenge is done. Should we go wash off? I mean, you’ve got two lovely ladies who are more than willing to help you shower~”
He flushed again. “I-I can manage on my own.”
She started to stalk around him, bent at the hips as she moved so she could remain on eye level. “You sureeeee~”
He was about to respond, but stopped as Yanagi spoke. “Um…I imagine it is within our consideration to do such a thing. It could be a good way to…break some barriers now.”
Setsua giggled. “What you don’t think I’m just teasing right~? I’m dead serious green~” She got behind him to whisper in his ear. “I’ll clean you with no hands~”
Yangi nodded. “I can move soap very easily with my quirk.”
Setsuna laughed. The sound loud and full, almost proud. “Not what I meant! But I dig it ‘Gi, it’ll be fun to feel what that’s like~”
Izuku just sighed, suddenly very aware of the same conclusion that Yanagi had reached. That the moment he had agreed to all of this, whether he won the fight or lost, it was really Setsuna’s victory.
He hung his head. An important lesson having been learned about not just focusing on the fight, but also thinking about why he was fighting.
The girl above him reached into her pocket, withdrawing her phone as she started typing. “Do you want our maid costumes a size too small or just normal?”
He put his head in his hands, and let out a deep groan of regret. Realizing just how much constant teasing he had signed himself up for. The noise only provoked giggles from the source of his anguish. Yanagi putting a comforting hand on his shoulder.
