ヒメ!!ラブ★ヒメファイト♪

You didn’t have to walk me here nerd, Katsuki grouses, although he’s not sparking up so Izuku takes it as a good sign that his friend either doesn’t mind that he tagged along or he just doesn’t care. Maybe the blond is even a little grateful that someone was willing to wake up early to see him off.

But it might be my only chance to see it up close!

Katsuki’s eye roll was practically legendary, the older teen huffing in amusement. You’ll be the second brat from our shit tier junior high to get in after me, just you wait Deku. Then he ruffles Izuku’s hair. I’ll see you after I ace these fucking exams.

Izuku nods, basking in the praise even as he waves at his best friend, the older boy heading into U.A. Other prospective students go with him and Izuku watches the process from down the street, waiting until the pro hero Hound Dog closes the gates. Once the school locks up, Izuku waits a few more moments before turning around and heading home. He had two more years and then he would be able to take the entrance exam to his dream school himself…

So distracted by his thoughts and musings, Izuku startled when something started rattling by a nearby dumpster. He doesn’t have anything but a pen and notebook and his quirk was next to useless without anyone else nearby, but Izuku still cautiously approaches to see behind the trash. There’s no small animals or even a person, just a small plush rabbit in All Might’s iconic colors. A frown mars his features – while he doesn’t have every piece of All Might merchandise in existence, he would recognize it on sight, especially something as cute as this!

Izuku doesn’t even realize he’s mumbling until a tiny voice interrupts him with, My, ya talk quite a lot dontcha?

The dark haired boy looks down to see beady blue eyes staring back at him. Izuku blinks. The stuffed rabbit blinks back too. Oh so ya can hear me, huh? Great, then you can form a contract with me and help others right? It doesn’t open its mouth at all, yet Izuku can hear it clear as day, voice bland but friendly, like a tired cashier who’s at the end of a boring shift.

Something in Izuku screams at him to run away, this wasn’t an animal with a quirk but some abomination with power that was speaking to him in his mind. He should forget about what he’s seen and heard, go about his day and forget this event even happened.

Instead he crouches down so he’s closer to eye level with the thing and gives a shaky smile. My name is Midoriya Izuku and I would love to help people!

Wonderful! If the plush could smile, it probably would of, but instead it just nods its head. I am – and whatever the rabbit says goes in one ear and out the other. Whatever its name is, Izuku can’t understand, can’t even attempt to pronounce it.

There’s an uncomfortably long pause before Izuku chuckles. Can I just call me Usahime-san? he asks.

The movement it makes is close enough to shrug. Good enough for me then. Now, let’s get out of here Izuku, Usahime says his name so casually, I really don’t wanna be here any longer than I have so far, and I wanna get clean!

---

I’m never doing that again, grouses the stuffed animal on his counter.

Izuku chuckles even as he turns the blow dryer on, intent on drying his new friend. Well, then maybe you shouldn’t let yourself get thrown in the trash, Usahime-san, the boy chides, a smile evident in his voice. I could have just put you in the washing machine instead of bathing you.

Usahime shakes itself to wring out more excess water from its stuffing. Yeah well, I was flying around and got attacked by a youma while I was lookin’ for a new Protector of Peace and Love. I was mostly out of it until you found me!

And that starts a very long and detailed explanation on Usahime’s home world, aliens, magic and more. Izuku stops Usahime often, asking questions, mumbling comments, and writing everything down in his pursuit of knowledge, even as the two migrate out of the bathroom and into his more secluded bedroom, ever wary that his mother will return from work early. Eventually, Usahime pauses in its explanation, as if deep in thought. Let’s just get on with this – I’ll create what’s needed to become a magical girl to help people!

The plush’s ears twitch and suddenly a strange device materialized on Izuku’s bed.

Izuku picks up the item, running agile fingers over the seamless surface. It’s about 10cm long, one end tapered to a soft point while the other was mostly flat save for a soft pink jewel in the middle of it. The device pulsed with power, making a shiver run down the boy’s spine. So how do I use it?

Usahime stared up at him with beady eyes. You put the magic plug in your butt, clench real tight while raising your hand in the air and yell For Love and Peace and then baddabing baddaboom, you’re a magical girl!

Izuku stares dumbly at the light green item in his hands before looking back at Usahime.

I have to do what now?

The rabbit heaves a sigh before continuing his explanation, this time focusing on its job as an intergalactic officer down a fugitive who was creating beasts Usahime calls youma that collects life force from humans to power some nefarious machine. And I can’t track down the perp if I’m busy fighting his creatures, so that’s where you come in!

That doesn’t explain why I have to put this up my butt to help you! Izuku hears how high his voice gets, flinching just a bit as it cracks at the end of his question.

Usahime is highly unconcerned though. The human anus has quite a large number of nerve endings – our magitech allows us to tap into them to boost your abilities and grant you the power to defeat youma. Anywhere else would be awkward to keep on you all the time.

The explanation makes sense, sure, but the idea of having to insert a foreign object in such a sensitive place still seemed very, very wrong.

Why don’t ya just try putting it in, it’s supposed to be very comfortable for you fleshy types. Usahime encourages softly.

It’s not a bad suggestion, honestly, but Izuku still hesitates. It’s awkward to strip down in front of someone even if that someone is an alien. Or is it? Do aliens have different morals than humans? Well of course they do, they were an entirely different species (or multiple species, really) and they might not even have real bodies since according to Usahime they were closer to sentient star dust and the concept of something as simple as clothes were utterly foreign and-

Izuku you’re mumbling again. comes the teasing lilt of Usahime’s voice. Just take off your pants and I’ll walk you through the rest.

Maybe trying it out would make it easier to process? With shaking fingers, Izuku strips down and takes the device from where he left it on the bed.

Usahime floats just a bit at eye level and motions towards the bed. All Might’s face has never looked so nerve wracking. Lay down, I’ll walk you through it okay? Izuku complies and the plush’s ears twitch once again, magicking a jar of something beside him. This will be the first time putting anything there, you’ll probably need to lubricate and stretch yourself thoroughly. As your body becomes more accustomed to the feeling, you will probably need less and less.

With a nod, Izuku starts preparing himself, working first one than two lubed fingers into himself under Usahime’s guidance. The sensation is odd and he’s not quite sure what to make of it but at Usahime’s prompting he still inserts the plug inside of him. Just like having his fingers inside of his butt, the plug feels strange and weird, and occasionally brushes something inside him that makes him feel a little tingly. Sitting – and then standing – up makes the feeling persist and Izuku shakes in embarrassment as Usahime has him jog in place a bit, ‘to make sure everything is sitting right’. Once the plush is satisfied it gives a nod for Izuku to go ahead and try.

Okay, I’m going to do it! Izuku says, psyching himself up. He clenches both his fist and his ass, and raises his hand in the air, For Love and Peace!

And then he feels it, a surge of power running up and down his spine, even as something covers his senses. It’s over in a moment but it feels like it lasts much longer before Izuku is blinking his eyes. He finds that he’s now wearing clothes – black spandex like shorts and sleeved crop top covered by a heavily modified sailor fuku, button up skirt and cut top to expose his stomach. A look in the mirror showed he also had a ribbon around his wrist as well as a gravity defying headband shaped like All Might’s iconic hairstyle. Izuku smiles at the mirror and is surprised by… just how cute he looks, a slight flush to his features.

Well looks like you’re able to move just fine, Usahime comments as it floats near Izuku’s side. Now, I’m sensing a youma nearby – this will be a great learning experience to use your powers and see what you can do!

Yeah! Let’s protect everyone! Izuku explains, pumped. He can feel the magic humming beneath his skin, like a crackle of electricity flowing through him. He was so excited for the chance to help people just like Kacchan will be! The feeling buoys him even as he opens up his window and uses his first feat of magic – a super powered jump – to propel him into the afternoon sky, ready to protect his town.

(Days later, Izuku records the transformation, starts cross referencing it against the henshin sequences of any magical girl shows he can find.)

Izuku frowns even as the remains of the slime youma begins to dissolve, leaving the energy that was taken from its victim. It was a low level beast that should have been easy to take care of, which meant the owner of the power was quite strong or –

Are my powers getting weaker? He asks even as his hands twine through the stolen power, taking hold of any of the corruption that was left before it naturally slips away, heading back to its owner. The roiling purple corruption that’s left over is handed towards Usahime who absorbs the residual with a happy hum.

It could be, the rabbit explains between bites of corruption. It’s been almost three months of nonstop mahou shoujo action and I don’t think you’ve recharged your love, have you? Izuku must have given his partner a questioning glance because Usahime continues. I can help charge your device, but you would get the most power boost by sharing your love with others. Hugs and kisses can help but sexual intercourse is by far the best energizer for our magitech. Usahime’s too used to Izuku sputtering whenever it says something that surprises the boy (which is often). I’m sure for mother would be willin’ ta help if you told her what you were doing.

That’s illegal.

Really? That’s so strange.

Usahime-san, your species reproduces through genetic cloning and manipulation and I guess you use sexual energy as a battery which is honestly really interesting, what if we could convert it with human tech. But on Earth, that is strange.

Fair enough, still, you are probably going to need to recharge somehow. Don’t you humans have… hmm, what are they called, brothels or something where you can show each other sexual love?

…I have a better idea that is probably not going to run the risk of getting me arrested. Can you go on home ahead and I’ll met up in a bit?

Sure, sure Izuku-kun, Usahime says. But remember, you’re going to have to show your love quite a bit to power back up, okay?

---

Landing on Katsuki’s roof is rather strange – Izuku knows his best friend’s home as well as he does his own apartment but the view from the sky is unexpectedly foreign that it throws the green haired middle schooler for a loop. It doesn’t matter though, he lands softly on the Bakugou’s roof in the twilight, magic keeping him from making too much noise. Already his final minutes transformed was winding down; Izuku quickly slides down the side of the house to land on Katsuki’s windowsill. The boy gives a few sharp taps against the glass and waits.

What greets Izuku the moment the blinds are pulled away and the window pulled up is sparking palms and an aggravated expression, that instantly morphs into confusion when he sees what exactly Izuku is wearing.

Deku, what the fuck. is his eloquent response.

Can I come in Kacchan?

The blond stares at his best friend for a moment longer before sighing and opening his window wider to let him in. Izuku slips in with a weak smile.

Please tell me you haven’t taken up crossplay while I’ve been busy with classes.

That startles a laugh out of Izuku, which helps release his nerves quite a bit. It helps lighten the mood enough for Izuku to explain the situation, even as the last remnants of his energy fizzles out, leaving him in his gakuran once again.

So let me get this straight, you signed up to help save people from near invisible monsters, but you need to have sex regularly to keep your powers up?Kacchan gives an aggravated sigh, and mutters something that sounds like only Deku. A large, calloused hand rubs against his uniform slacks, pulling Izuku closer to his best friend.

Izuku, not used to being so close, flushed hotly but still nodded. Y-yes, Kacchan. I thought you would be the best person to help me be a hero like you.

The blond snorts even as pulls his arms away. Fine, I’ll be more than happy to help you recharge but it’s going to be on my terms got it? At the green headed nod, Katsuki continues, unbuttoning his own Jean’s. I want to watch you transform and then I’m going to teach you how to show your love the right way. Let’s start by you getting pretty for me, I wanna watch you transform.

Izuku gulps, anxious because this will be the first time he’s ever transformed around someone other than Usahime. But still, he gathers his courage to do it. Kacchan is willing to help teach him how to love someone properly, so he can’t disappoint. Izuku takes a step back and raises his hand. With a clench and his transformation phrase, Izuku is once again decked in shorts and skirt although for the first time, he stumbles out of his transformation, feeling drained.

Katsuki catches him by the shoulders before placing easy pressure against them, urging Izuku to kneel down. He goes willingly and finds himself at eye level with the blond’s half opened pants.

All right Deku, you actually watched any porn online before?

Izuku flushes but shakes his head. Sure he’s gotten the occasional pop up, but he’s always been quick to exit out of any such scandalous ads.

Katuski hums above him before his hands move from his shoulders. Then I’m going to tell you what to do, and you’ll listen okay? The blond sits back on his chair, legs spread wide as he fishes his cock from the confines of his boxers. Now why don’t you come over here and touch.

The green haired boy scoots closer, fingers tentatively brushing against Katsuki’s hard length. It’s warm, pliant but still solid beneath his touch and Izuku gasps just a little at the feel. He doesn’t need any coaxing to start touching more, both hands sliding over Katsuki’s cock, giving it a few pumps. Precum begins to bead at the top and Izuku doesn’t even think, he’s leaning down to suckle at the head.

Fuck, yes, you want my cock that much you slut?

Izuku flushes at the words, considers pulling up and off of Kateuki so he can pout and deny, but then he feels the blond grip at his hair and push him further down at his cock. He can feel his throat fluttering at the intrusion, but Izuku swallows past, trying to open himself up more so Katsuki can use him better. Tears prickle at his eyes, drool drips past his slack lips as he works to slurp it up as he goes further down. Usahime said that the best way to recharge is by showing his love, and internet forums say that the best way to show it is by taking a cock deep down his throat.

Above him, all he can hear is Katsuki praising him, telling him how good he takes his love, how good it feels inside of him. Insistent hands pull him up a tad when Izuku begins to choke, gives him a moment’s breath before pushing him back down, urging him to take more of Katsuki down his throat. The blond grunts and pushes Izuku even further down until his lips are touching wiry hairs. That’s all the warning he gets before Katsuki begins to cum. Izuku swallows on reflex, pleasure shuddering through his body at the taste before finding himself pulled up by his hair so only the head of his best friend’s cock rests between his lips. He sees Katsuki’s hand fisting at his own length, gonna finish off but don’t you fucking swallow it, I want to see it in your fucking mouth, got it?

Izuku looks up at Katsuki and nods minutely and that seems good enough before he feels more cum splurt on his tongue. The green haired boy consciously doesn’t swallow, stays suckling at the head a few more moments to make sure Katsuki is done before moving away.

Open up, Deku, Katsukin orders. Izuku listens, opens hits mouth to show off the small pool of cum the blond left him. He hears a hum before Katsuki says, Great, now go ahead and swallow it, but keep your mouth open for me, won’t you?

Complying is easy, Izuku closes his eyes and works his throat, neck extended to give Katsuki the best view possible as he swallows. He had so much more energy now, with just a blow job! Thank you Kacchan! Izuku opens his eyes and is treated to a red faced Katsuki. Did sex make him that flustered too? He’s just about to ask when he feels one of Katsuki’s legs nudge between his own, eliciting a squeak from him. Kacchan, what’s that for?

You’re fucking hard from sucking me off, pervert! Katsuki laughs. Izuku looks down and yeah, he can definitely see the obvious erection he’s sporting beneath his skirt. He’s sputtering, looking for words as he flushes darker but before he could even formulate words, Izuku feels pressure against his cock. It’s not a lot, just Katsuki nudging against him with his foot. That one bit of contact is enough to send a jolt of pleasure through Izuku, and he doesn’t even know he’s moaning as he cums until Katsuki begins to shush him, hand over his mouth to muffle his sounds.

Izuku is still panting against Katsuki’s legs when there’s a brief knock at his door. At least there was no attempt to open it. Fucking what is it old man?

Masaru sighs through the closed door. Is everything okay in there?

Just fine, Katsuki growls out. And because it’s his father he adds, I forgot the sound was so loud on my phone and I turned off bluetooth.

Don’t keep your music too loud son, you don’t want to damage your hearing anymore than you do with your quirk already. You shouldn’t be doing that anyways with your hearing aids-

I have them set to reduce sound, I’m fine.

There’s a pause before Masaru leaves, with a reminder that they’ll be having dinner in an hour. Then there’s the muted sound of him walking away and down the stairs, most likely to the family room or his office. The whole time Katsuki and his father were talking, the blond had kept one hand loosely over Izuku’s lips and the other running through his hair, a gentle reminder

Izuku is still catching his breath after what was definitely the best orgasm of his young life. Thank you Kacchan, he repeats, his tone just a little spaced out and reverent.

He can feel those long fingers pull at a strand as Katsuki chuckles, Like I wasn’t going to help you when you explained why you’ve been fucking ditching me. Who would be my sidekick when we go pro if you do something stupid and die ’cause you don’t get my cum when you need it?

They stay like that a few moments longer before Katsuki reminds Izuku he needs to get home to eat with his mother. I’ll let you know when you’re ready for your next dose, nerd.

---

Less than a week later, Izuku is clearing up another youma, body primed with energy when he receives a message on his phone. He holds his hand out and a display pops into existence to let him read it:

Meet me at your school, I'm gonna fuck your ass so hard, you'll have Love for days.

He doesn’t even take the time to go back into his regular clothes, using magic-assisted leaps to head back to Orudera as fast as he can.
