Unable To See Her Own Faults... Or Her Own Changes
With that annoyance gone, Katsumi sighs, finally able to relax a little. Scrolling through her phone she browses various UA student's social media pages. Oddly enough, the action doesn't strike her as strange, instead it brings her a level of comfort she hasn't known in quite some time. The hothead looks at some of the older students, smirking when she sees Mirio Togata. "Huh... when did he get kinda cute..."

She lingers on his profile, staring at his shirtless self, an image of him next to a river where he had a successful mission. Looking around, Katsumi bites her lip, the corruptive energy within her threatening to take over. "Maybe..." She wonders if she has enough time to get off again before Jiro gets back. Earlier she had hidden in the bathroom, locked away where no one could bother her. But now... She feels herself growing hot at the thought of Jiro walking in on her. "Fuck... what's wrong with me?"
The heat inside her grows more intense, trying to tell her what she really needs. For a few moments she's able to ignore it, until that heart throb image of Mirio grabs her attention again. She feels her pussy pulse with need, swelling up and begging her for attention. "Ah hell... if that runt wants to walk in on me, it'll be her own fault..." Katsumi rationalizes the situation, and quickly shoves a hand down her skirt.
Wasting no time, she plunges her fingers deep inside herself, she needs to get off quick... She stifles her moans, simply gazing at that chiseled chest, those abs, those pecs... "Fffuck~" She feels the heat spreading inside her, thanking the rageful girl for not putting up a fight. She rocks her hips back and forth, bringing herself closer to orgasm as her hair begins to lengthen. The girlish sounds grow louder, her lips plumping up with each cry. "Oh shit... f-fuck me~" She whines, imagining Mirio taking her right then and there, pinning her to the bed as he rams that monster cock into her.
Katsumi's breasts expand further, becoming hefty globes as the buttons on her top burst, revealing her stylish tiger print bra underneath. She revels in the sensation, so close to reaching that sweet sweet orgasm. That edge is so close, just a few more pumps and-
"What the HELL are you doing?!" Behind her, Jiro stands in the doorway, a horrified look on her face. She drops the soda can, petrified at the sight of the now voluptuous Katsumi fingering herself to Mirio.
"Ah- Wha- Wait... It's- Shit it's not what it looks like-" Katsumi stumbles over her words, her newly ditzified mind trying to find some reasonable explanation, until finally her usual self shines through just a tad. She stands up, suddenly changing her tone to a more assertive one. "Look, its just... tell me he isn't fucking hot as shit!" She shoves the phone into Jiro's face.
"Mirio?! Since when- Why do you look so?" Jiro scans Katsumi's appearance, her tan even more obvious, and her body much more pronounced. "What the hell happened to you?"
Unable to sway her friend so easily, Katsumi's pleading face grows more upset, her face red with embarrassment. "Oh don't act like you don't get it, you fucking slut!"
"Wha- What?" Jiro asks, putting her hands up.
"Don't play dumb with me you fucking whore, I know you know what I'm talking about... all those convenient bathroom breaks, all those times when you suddenly can't come over because 'I'm with my family'!" Katsumi throws her phone to the bed, shutting the door behind Jiro. "You lying fucking skank..." Stepping forward, Katsumi pushes Jiro against the door, reaching down under the punk girl's skirt.
"I know you have feelings for me, just like all those other bitches... just like Izumi..." Katsumi smirks, her mind making up any possible way to make things about herself. "I'm not the loser here Kyoka... I'm not the weakling carpet munching whore imagining myself with my only fucking friend!"
Jiro winces at the pressure on her shoulder, the strength from Katsumi is astounding. "Kat... I really don't know what you're talking-" She's cut off as the bimbofied girl leans in, sealing their lips together.
Kyoka groans, feeling those manicured nails teasing the edges of her panties. She breathes through her nose as Katsumi's tongue penetrates her mouth. Suddenly a burning fire appears in her stomach, as her pussy grows damp. She tries to push away, but literally backed into a corner, she has **** but to take it. "Maybe- Shit~ Maybe Izumi hit her too hard... made her crazy!" She thinks.
The heat inside her blooming quickly, Katsumi makes quick work of her. Within seconds, Jiro can't help but feel the pleasure emanating from those skilled fingers and plush lips. Her eyes close, as she feels her chest growing tight. Her shirt rides up as her tits expand, revealing her thin waist underneath. Her hair pushed against the door grows wild, without gaining much length, simply growing thicker and lush.
Katsumi breaks the kiss, leaving Jiro unsatisfied as she crumples to the floor. "There, now you know how it feels bitch..." Katsumi hisses, turning back and flopping on her bed, grabbing her phone in a hurry to get back to the image of Mirio.
Jiro is left dazed, holding her head as her thoughts feel sluggish. The heat in her tummy has subsided, but the tingling in her pussy remains. "You... didn't let me cum..." She says quietly, that fact suddenly important to her. Katsumi ignores her, causing the punk to blush. "Why does that make me feel so..." She looks down at herself, a face full of her new tits only adding to her confusion. "What the hell? Katsumi what did you do to me?!"
