Reaching The Dorms... And A Well Needed Punishment

Humming brightly as she struts through Musutafu, Izumi revels in the shocked faces and lustful looks alike from everyone that sees her nude form. The last couple days has definitely started something big, something big enough that even the local heroes don't seem to want to mess with her, only Mirko being brave enough to try and pick a fight with the amazon.
Though it's true she was outsmarted... going through the event in her head again has given Izumi a new perspective on things. Sure she lost... but like, so what? If her bimbo powers are strong enough to change an entire block of the city, there's no way she won't have Mirko and All Might turned by next week~
It may be a devious thought, but to her, bimbofying others is a way to help. Afterall, who doesn't want huge tits like hers... or a monster cock between their legs? This way of life is fucking heaven!
Making it to UA, the front gate is wide open. The metal structure welcoming any and all that want to join the cause. Barely stepping through, she can even hear the debauchery from the dorms, loud moans and pleasurable screams... She licks her lips, it's been too long since she's had her pussy stuffed, or sat on someone's face... "I wonder..." She puts a finger to her lip, looking around for someone she could have fun with, but at first glance she can't see anyone... Until that is she sees a small group by the front door of the school.
Heading over, Izumi waves to Yaoyorozu and Recovery Girl, only noticing the sexy redhead on all fours by their side. "Who's this cutie?" She asks, reaching the duo and putting her hand on the girl's head.
Yaoyorozu pockets her phone and smirks. "Just one of Midnight's 3rd years. Apparently she was being naughty and needed some extra attention..."
The redhead giggles and purrs. "Yeah~ I've been such a naughty girl~"
"Sounds fun!" Izumi chirps, paying no more attention to the girl, instead her expression turning to one of worry. "Hey, like, before I forget... I kinda wasn't able to get All Might..." Izumi says, looking away from the smartest of their new group.
Yaoyorozu sighs, obviously a bit annoyed. "Too much for you? Alright ya big lug... what happened?"
Izumi tells Yaoyorozu about what happened, how Mirko showed up out of nowhere and her discovery of the extent of her new powers. At first Yaoyorozu seems upset that Mirko was able to best Izumi, but as the story goes on the gears start turning in her head. "So... you felt drained, but now you're feeling better?"
Izumi giggles, flexing her arm. "Yeah I think so, I was totally weak when I started walking back, still a bit sore too, but I think I'm better, why?"
Turning her head to the locked door, Yaoyorozu runs a hand along the thick metal sheet put up by the school's security system. "Well... I sent Jiro on a mission to go find Hatsume while you were gone to try and get this thing open. But with a power like that, you think-"
Izumi interrupts, cracking her knuckles and stepping in front of Yaoyorozu. "Way ahead of ya babe~" Placing her hands on the door, Izumi once again activates her ability. Pink sparks begin to form around her fingertips as her eyes glow. The energy not nearly as built up as it was in the city, Izumi breathes out, pushing the energy into the door.
Yaoyorozu and Recovery Girl both step back, narrowly avoiding the energy themselves as the door shines brightly. In a moment the blank sheet of metal shifts, gaining a flowery design and staining to a shade of pink. In the center, a line shoots down the door, creating a seam as a heart shaped insignia burns into the material. Taking a step back, Izumi giggles as a small tune plays from the door and it slides open to both sides, her power having turned it into an automatic sliding door, unconnected from the rest of the building's security.
Yaoyorozu and Recovery Girl are shocked, their jaws hanging as the implications of such power hang in the air. "And that wasn't hard for you...?" Yaoyorozu asks.
"Nah, not really. I think I'm gettin' the hang of it, y'know?"
"Yeah, I guess so..." Yaoyorozu responds, stepping into the doorway and looking around the halls.
Giving the science nerds a second to recover from their shock, Izumi pats them both on the back. "Well, glad I could help with that, sorry you had to send Jiro to get Hatsume..." Pushing off, she takes a step back. "But anyway, I've been trying to hold it together for a bit now, but I REALLY need to get off, it's been like, years since I was with Ochako and Mina..."
Turning towards the dorms, Izumi once again pats the redhead girl's head, before heading off. She really hopes Uraraka is finished with the library takeover by now...
Watching the strange amazonian babe leave to the dorms, the redhead continues holding strong for her Mistress. Staying put and not causing a scene, she rubs her thighs together, thinking of all the dirty things Midnight could be up to right now...
At the same time, on the 3rd floor of the 1-A dorms, Midnight licks her lips, gripping a chain leash in her hand as ties Shiozaki to the wall, the leash making sure her head stays firm. The 1-B student let's out a small whimper, unable to turn her head as she stands in the corner of the room. Around her, boxes of strange looking equipment and more obviously lewd devices all catch her attention. Always a pure girl, she gulps, something about it all trying to ignite a sinful fire in her tummy.
Pulling on a pair of latex gloves, Midnight grabs a simple vibrator, examining it before nodding. "You seem like such a pure girl..." She starts, facing away from Shiozaki. "Unfortunately we could use your help, so I won't go too hard... I know how sad you must be to not be able to join that lovely girl in complete submission. But don't worry Miss Ibara... I still know how I can help you shed that wall you've put up~" She turns back to face the girl, a sadistic smile on her face as she tilts her head to the side.
Closing her eyes, Shiozaki tries to make a prayer in her head. Her thoughts are swimming strangely, unable to focus on her pure thoughts as the sounds of Midnight grow closer. She berates herself, what's wrong with her...? Why can't she just move, use her quirk to bury Midnight and escape? It should be possible, she just needs to bury these feelings and-
Before she can bring herself to action, Midnight's lips meet her own, and her eyes shoot open. A rather uncharacteristic move from the X-rated Heroine, she can't help but shiver as her lips tingle from the contact.
Holding herself close for a moment, Midnight savors the taste of the girl, something she doesn't often get to do. She's so sweet... still so fucking innocent, even after being tainted. Breaking away, she looks into the girl's soul, licking the strande of saliva from her lips as she studies the look on the first year's face.
After what feels like years, Shiozaki clears her throat, attempting to speak. "M-Miss Midnight... I don't think this is something-"
Again she's interrupted, this time by a hand on her shoulder. With the heroine's right hand gripping her, Midnight's left hand barely moves, her thumb flicking up to hit the switch on the vibrator. Shiozaki's eyes go wide at the sight, suddenly realizing what's about to happen. She tries to shake her head, but Midnight leans in close, her lips tickling the edge of the girl's ear. "Come on baby~ Struggle more for me, earn your punishment~" Her hand moves closer, the vibrator closing in on Shiozaki's thighs. "You've been such a naughty girl, denying your true nature as my little slut... You've been such a good girl your whole life, so good... until you decided to resist!" Midnight grits her teeth at the end of her whisper into Shiozaki's ear, the grip on her shoulder tightening and the vibrator pushing up against the student's skirt.
A small gasp escapes Shiozaki's lips, something she's never heard from herself before... She blushes, embarrassed by the lewd sound she created. "Ah~ Midnight... we can still-"
"No... we can't..." Midnight pushes the vibrator against her harder, pushing it between the girl's thighs from the outside of her skirt. "Don't you see Ibara? This isn't something you fight... It's something you embrace. It's a fucking gift, and every second you fight the fact that you're just a submissive slut, the longer you have to fight and suffer as some prudish bitch." The heroine growls, her eyes flashing pink as she grows annoyed. "Fuck! I wish I could just break you now..." She frowns, pulling away from the girl slightly to take a breath. "But Yaoyorozu and Recovery Girl are right... We need you."
The look in Midnight's gaze shifts, and grows more focused, her sadistic eyes softening slightly. "Alright, sorry about this, but I can't have you as a pet... instead, we're gonna put you to work!" In a swift motion, Midnight rips at Shiozaki's skirt, revealing her already glistening folds to the air. She gasps again, looking away as Midnight activates the vibrator once again and presses it directly to her engorged clit.
Immediately her legs tense up, a pit of fire forming in her stomach. Shiozaki can't contain a moan as she shakes her head, trying not to look so whorish. "I'm... ahn~ Not that kind of... girl!" She screams, her voice going higher at the end of her protest.
Midnight purrs, sensing the next change blooming inside Shiozaki. "Mmm~ You sure?" Looking down, she watches in delight as D-Stress' wonderful energy courses through Shiozaki's body. First, she sees the tightness in the girl's chest, her uniform straining as she's gifted with a bountiful bosom. Shiozaki's stifled moans grow louder and less inhibited by the second, until they can be heard throughout the building. Quickly, the religious virgin of class 1-B falls to the corruptive energy, her protests weakening.
though her eyes are closed, Midnight watches in delight as a flash of pink comes from beneath the girl's eyelids, a telltale sign that her work may be done. She smirks, taking a step back and tossing the vibrator. "There... how do you feel now, slut?"
Panting heavily, Shiozaki's final change occurs rather abruptly, a few vines atop her head curling up, until they form what looks like a pair of prickly horns sprouting from her now even more wild mane. "Wha..." She pants. "Why do I feel so... warm..."
Later, with the leash discarded and her new project well on her way to being completed, Midnight watches as Shiozaki pulls on the last part of her outfit. Using Midnight's advice, the girl looks down at herself, her twisted mind now able to appreciate such a daring look... though, much like the last transformation she endured, she still gets the feeling that this is off. She puts a hand to her head, resisting the urge to indulge in her new body. "Shit... Are you sure this is good Midnight?"

Before Midnight can even answer, the door to the room slams open. Startling Shiozaki, her eyes go wide at the sight.
"OMG look at you!" Kendo beams, her and Pony practically bouncing up and down as they take in their classmate's new form. "Ibara, when did you get so fucking hawt!"
