The Successor (My Hero Academia)

In an instant, Momo makes her decision. Izuku wanted her to prove herself to him. To prove that she could do what she’d told him she would do, to be what she’d told him she wanted to be. But if she went around throwing his name out like it was some sort of magic spell, then how would that prove anything at all? No, Momo needed to ensnare Itsuka on her own merits. She needed to seduce the other young woman with her own capabilities and make her submit.
 
And if Itsuka Kendo wasn’t interested in submitting… then Momo would go and find another candidate. It wasn’t as though she was going to force the ginger girl to do anything she didn’t want to do. That said… Momo felt like her best bet here was to come on as strong as possible. They were still holding hands right now, with Itsuka staring at her with wide eyes. But it wasn’t enough.
 
Twisting her hand around, Momo adjusts her grip on Itsuka so that their palms are suddenly facing each other and flat, allowing her to push the other girl back. Not expecting it, clearly caught off guard by just about everything about the situation, Itsuka blinks rapidly as she allows herself to be walked all the way back to the nearest wall.
 
As soon as her back makes contact with said wall, Momo brings her other hand up and slaps it down hard right next to her head, making the ginger-haired heroine-in-training flinch from the sound.
 
SMACK!
 
Smiling coyly, Momo licks her lips as she tilts her head to the side. Even after all that, Itsuka hasn’t tried to pull her hand free of Momo’s, nor slip out from her. She’s positively quivering, in fact.
 
“… I suppose I should also ask if you’re seeing anyone, It-su-ka~”
 
Elongating her name has its intended effect. Itsuka’s face goes bright red, the ginger biting her lower lip as she trembles in Momo’s grasp.
 
“A-Ah… u-um… n-no? I’m not… I-I’m not s-seeing anyone…”
 
That stutter was unbelievably cute. As Itsuka stammers out her response, Momo is reminded of how she’d acted the first time Izuku had come onto HER. She’d been a little more composed than Itsuka was now… but then to be fair, Izuku had been a lot less aggressive. Having seen how he could really be at this point, Momo could recognize that for whatever reason, Izuku Midoriya had treated her with almost kid gloves in a way.
 
Was it because he thought she couldn’t take it, or because he had greater feelings for her than the others? Momo didn’t know one way or the other, truth be told. But she DID know that right now, that wasn’t important. What was important was pressing her advantage. And seeing as Itsuka had just confirmed she was currently unattached… Momo decides to do so by going in for a kiss.
 
She’s treated to the sight of Itsuka’s green eyes growing even wider as their lips make contact. Her fellow Class Rep is not at all ready for Momo to kiss her, and she squirms briefly as it starts… but she doesn’t fight it. Instead, she lets out the cutest little whimpering moan into Momo’s lips as the raven-haired heiress dominates the kiss, taking full advantage of Itsuka’s shock and embarrassment.
 
However, was it JUST shock and embarrassment, or was there some level of submission lurking in the other girl’s heart? That’s what Momo had to know. She had to know if Itsuka was proper sacrifice material. If the ginger wasn’t willing to submit to Momo, then she would never be willing to submit to Izuku. However, if she submitted totally and utterly, then this would be a piece of cake. There was also the midground where she reluctantly submitted, but Momo was hoping for one of the other two options so she would at least know fast whether Itsuka was the right candidate.
 
That said, the heiress untwines her fingers from Itsuka’s, finally letting go of the other girl’s hand. Itsuka, who is far too focused on the fact that she’s getting the ever-living daylights kissed out of her right now, doesn’t even notice. Her freed hand falls limply to her side, matching the other one as Momo smirks… and promptly shoves HER freed hand down the front of Itsuka’s skirt.
 
“Mmph!”
 
As surprised squeal leaves Itsuka’s lips, mostly swallowed up by Momo’s mouth as the raven-haired heroine-in-training pushes right past her prey’s panties as well, her hand cupping Itsuka’s mound and her fingers sliding across the other girl’s pussy lips.
 
It’s at that time that Momo freezes up. She hates to admit it, but it happens. Luckily for her, Itsuka also freezes up, the two of them both unmoving as Momo’s fingers remain in touch with Itsuka’s sex. It’s just… well, it finally all catches up with Momo. She’s really leaping into things with both feet, isn’t she? Despite having never done anything like this with a girl before.
 
She’d seen a lot of porn over the last few days, especially involving her fetishes. She’d needed to put a word, or even a set of words to what exactly she wanted from Izuku. What she wanted to BE for Izuku. So yes, she’d done plenty of research. However, this was her first time doing anything so… hands-on. Especially with another woman.
 
Momo definitely liked both boys and girls. Specifically, she loved the thought of preparing another girl for Izuku, to prove herself to him. It was an exhilarating thought that filled every fiber of her being with excitement. But even still… to actually DO it was something else entirely from thinking about doing it.
 
But then… what other choice did she have? She wanted to be with Izuku. But more than that, she wanted to earn the right to help him dominate his other women, to not just watch him fuck them, but also participate in how he fucked them. That was what Momo had told him, and it was the truth. So… she couldn’t back down now. She couldn’t balk just because she was teasing another girl’s pussy while kissing that girl on the lips.
 
With her resolve firming back up, a strange determination fills Momo. Unfortunately, it was still long enough for Itsuka to realize something was wrong. Their lips have drifted apart as they both stood there, staring into each other’s eyes. The ginger-haired Class Rep looks concerned for her, worried even.
 
“… Momo…”
 
Itsuka wasn’t supposed to be worrying about her. She was supposed to be worrying about what Momo would do to her if she didn’t OBEY! A little snarl escapes the heiress’ lips, as she promptly shoves two fingers up inside of her fellow Class Rep. Itsuka’s eyes widen and she squeaks as her hands grab at Momo’s arm for support, her body shivering at the sudden penetration.
 
“M-Momo!”
 
This was it. This was now or never. Make or break. Using her other hand, Momo cards her fingers through Itsuka’s hair and grabs down hard, gripping tightly at the other girl’s ginger locks as she forces Itsuka’s head back. Leaning in close, she smiles at her.
 
“Itsuka. You want to be my good girl, don’t you? You want to be obedient.”
 
Whimpering some more, Itsuka looks caught off guard. Momo pushes on however, not letting up for even a second. She even pushes her fingers in and out of the other girl, drilling into Itsuka’s wet cunt up to the second knuckle before pulling back again.
 
“I need to know you’ll be good. I need to know you can be taught, Itsuka. Do you want to belong to me? Do you want to be mine?”
 
Itsuka is now staring down between them, at where Momo is fingering her so aggressively. The ginger-haired girl is panting noisily, her breathing coming out in heaving breaths.
 
“I… I…”
 
Momo grunts… and pulls her fingers back quite suddenly, leaving Itsuka empty. She does NOT remove her hand from Itsuka’s panties however, merely cupping the other girl’s mound.
 
“Or we can stop right here. If I’m coming on too strong… just say the word. It isn’t my intention to make you uncomfortable… It-su-ka~”
 
With her piece said, Momo settles in to wait. She counts the seconds in her head and decides then and there if she even gets to ten, she’ll back off. Itsuka won’t be right for this. She won’t-
 
“N-No… d-don’t stop… please. I c-can be your good girl. I can… I want t-to belong to you.”
 
In the end, Itsuka doesn’t even let her get to three before she speaks. Momo smiles and slides her digits back inside of the ginger heroine-in-training. Itsuka gasps, panting some more as Momo fingers her right there against the wall.
 
“Good girl. You’re my good girl, aren’t you?”
 
Shuddering, her juices positively overflowing across Momo’s fingers, Itsuka’s eyes are lidded even as she nods her head.
 
“Y-Yusss… I’ll b-be… Momo’s… g-good girl…”
 
She was perfect. Momo smiles, even as she tightens up her grip on Itsuka’s hair once more and gives it another firm tug.
 
“Not Momo. When we’re alone… you address me as Mistress, alright?”
 
Itsuka’s pussy walls clench down even harder on Momo’s fingers at that command, and Momo knows even before the other girl responds that she’s found the perfect candidate.
 
“Yesss… Mistress…”
 
Some training and Itsuka would be prepared for Izuku in no time. Momo giggles to herself as she continues dominating the other girl. She could hardly wait~
 
-x-X-x-
 
He’d knocked Himiko out for a period of seventy-two hours, but always intended to come back to her before that time ran out and wake her up himself. He’d hoped he would do so after giving back her Quirk, albeit in a new and improved state.
 
Luckily, that was precisely what he’d returned to Kurogiri’s bar in order to do. A room upstairs had been repurposed into a bedroom with a couple of cots. It was onto one of these that Tomura had laid Himiko down to rest, allowing the blonde to sleep the day away none the wiser to what was happening around her.
 
As Izuku kneels next to Himiko’s cot, he considers her sleeping features for a moment. She certainly looks far more peaceful like this. There’s neither the lustful desire mixed with the insane need to make him bleed, nor the horrified teary look after he took her Quirk. Letting out a sigh, Izuku brushes a lock out of Himiko’s hair and then looks inward, considering her Quirk.
 
Transform had had long enough now within his repertoire to ‘soften up’ so to speak. With more time and practice, he might even be able to speed up that time frame, strengthening his ability to modify Quirks alongside stealing and gifting them, both of which were already instant for him. Regardless, for now… he considers the change he thinks will be most impactful to Himiko. He HAS been considering it all day long, and he’s come up with an idea of sorts.
 
See, Himiko’s Quirk demanded that she drink the blood of her victims in order to be able to Transform into them. No blood, no Quirk Use. And most Quirks LOVED to be used. So of course, it had constantly pushed Himiko to seek out blood, and that had eventually evolved into a full-blown complex rather than just a need to use her Quirk. She was addicted to the sight of blood, to the taste of blood, to the… everything of blood.
 
But what if her Quirk was no longer pushing her to seek out blood at all costs? What if instead, her Quirk was a lot laxer? Reaching within him, Izuku takes Transform and tweaks it. His idea for doing so comes from the way All Might gave him One for All, all those months ago. Izuku hadn’t had to drink All Might’s blood in order to be granted his Quirk, though he probably could have. No, instead, all he’d had to do was eat a couple of strands of the Number One Hero’s hair and… viola. Quirk Transferred.
 
That’s what he does with Transform. He makes it so all Himiko has to do is consume the DNA of her targets in order to be able to transform into them for a time. Hair is fine now for her. So is even a drop of sweat. Hell, even fingernails… but god, that would be particularly gross. Izuku assumes hair will be Himiko’s focus, now that she’s not being pushed into her constant need for blood by her Quirk.
 
With the Quirk altered, Izuku reaches out and touches Himiko, putting the Quirk back where it belonged. It slots into her quite easily, given it was her Quirk in the first place. As it fits back into place, Izuku uses his other Quirks to study her for a moment, just to make sure nothing is going wrong on the inside. When she doesn’t abruptly develop Super Cancer or anything like that, Izuku slowly nods… and then finally reaches out and touches Himiko’s forehead, waking her up.
 
The blonde’s eyes slowly peel open, staring up at the ceiling as she lays there on the cot. Izuku kneels there beside her and waits… until finally, her gaze shifts over to him. The moment she notices him, she reels away, immediately scampering off of the cot and backing all the way up to the furthest wall. Izuku is fine with this, he’s between her and the door and has a dozen Quirks that will let him disable her besides.
 
Holding up his hands, he offers her an apologetic smile.
 
“Sorry Himiko, but it’s back now. I returned your Quirk. You can feel it, right?”
 
Himiko bites her lower lip and then her eyes go unfocused for a moment before she shakily nods, staring at him in confusion.
 
“Feels… d-different.”
 
Good. Or at least, Izuku thinks that’s good. He beams and proceeds to explain what he’d done. How her Quirk had been altered before he’d returned it. How she no longer needed blood specifically in order to make her Quirk work.
 
He goes on to explain what he believed of what her Quirk was doing to her. How it had forced her to develop a dependency on it by giving her an addiction to blood, whether it was the sight of blood, or the taste, or the smell.
 
Himiko listens in silence the entire time. At some point, she slowly stands up, using the wall behind her to push herself to her feet. Izuku does the same, continuing to talk as Himiko licks her lips, clearly considering what he’s saying.
 
Eventually, he runs out of things to say. Eventually, his explanation runs its course and he’s left standing there, waiting for Himiko Toga’s response.
 
“So… how are you feeling?”
 
Himiko blinks at that, before looking down at her hands and herself for a moment blankly. When she finally lifts her gaze again, Izuku lifts an eyebrow in response to the look on her face.
 
“I…”
