Tsundere Fever (Maki Shijo Tg) (Patreon)

Maki stared at her age old friend, wondering if she could truly bring herself to so selfishly meddle in the life of someone who supported her through every hardship. An anchor to her every-

"You know Tsubasa and I tried it from the back yesterday. You know how his dad is always worried about anything premature happening. And he- hehe, he was a bit awkward at first, but after the third time he really showed how fast of a learner he was."

Maki took this in, giving Nagisa her blankest grin, the epitome of friendly support. YES! SHE WAS GOING TO RUIN HER LIFE AND TAKE WHAT WAS RIGHTFULLY HERS! THIS DAMN SEX HUNGRY MAN EATING BEAST IN HUMAN FLESH! That's what Maki thought at least, pausing as what she said was, "Ah h-how interesting. Could you give me a second to grab something from my locker? You can tell me all about it once I return."

She was fuming, wondering how her only crush and her best friend could go so far! And act so indecently! Th-This was high school and that stuff was for marriage! Arrgh she couldn't help but blame herself for inadvertently saying she'd like to know the details, thinking she could at least get some second hand arousal from Tsubasa's exploits and self inserting, but all she felt was pain. But this was only temporary, her admittedly bizarre trip to India granting her something special, though it looked like a cheap wand and smelled like Turmeric. The old lady had sensed her love problems without her even talking, and she had promised this would make Tsubasa and her a couple if she used it on her friend, though she'd have to share. Something about twinning and forcing your chakras into a person. Admittedly it all sounded stupid, but she was not in a logical mood, the constant sex updates driving her crazy as she walked back to the hallway, aiming straight for Nagisa. She could feel a tremble in her arm, the wood growing hot, Maki ready for something to go right for once in her li-

"Oh hey Nagi~ Chan!"

Nagisa turned, for some reason feeling something was off as her boyfriend rounded the corner, grabbing him by the shoulders as she twirled him around to the front. She didn't know why, but she never doubted her instincts even if it felt nonsensical.

"Er, is something wrong?"

"No I just wanted to see you in the right li-"

"GAH!"

Tsubasa stiffened to a board, trembling as something hot rammed into his back, the discomforting feeling of the weird heat probing into him, becoming one with his body as he felt it disperse throughout, giving his blood a heightened tang to it, a familiar scent gracing his nostrils as the weird spasm passed.

"Sorry, muscle spasm or something. Anyways-"

Maki was horrified, quickly hiding behind the corner, holding her breath till his "Anyways-" as she calmed her beating heart. She was annoyed she had wasted money on an obvious scam, but that was better than the alternative. Her precious Tsubasa seemed fine and this was just a stupid idea anyways. She would have to go to her friends for some tea to vent later she decided and probably weep about her own desperation. Neither of the trio noticed however as a slight spasm ran chills down Tsubasa's spine, a slight tightness growing at the small of it, making it even smaller with a crick, a sudden warm surge in his spine rounding the vertebrae.

It was strange though, the circulating warmth felt good to him, incredibly good. It was almost like he was being gently caressed all over, his cock twitching, yet the more he talked with Nagisa, the more of a... buzzkill she was? He still felt horny as she did her usual teasing, her fingers gently touching him in just the right spots to imply what they'd be doing after school, but he just felt more and more annoyed by it. Another pop was lost under his unenthusiastic nodding, suddenly feeling a bit intimidated by her. She felt taller, though in reality it was his arching back stealing inches from him.

The back of his black uniform undershirt scrunched as the material turned silky, avoiding the tell tale drooping it otherwise would have shown. What was this feeling? Was he... intimidated by her? There was something hungry about her he never noticed before. Well no he liked her hungry side d-didn't he? A shiver ran through him, hairs shedding as his skin turned creamier, a completely smooth expanse that was far more tender than what he was used to. It was adding to the overall agitation, all these new bits feeling itchy under the men's uniform, hair spilling down bit by bit over his eyes as he worriedly noticed Nagisa's eyes were almost level with his, l-like she was gaining on-

"I think I need to get going. I uh, have to help Shigi and the others back in the classroom."

She seemed unconvinced, but shrugged and let him go, looking vaguely annoyed. He could feel her icy glare as he moved towards the student council room, shivering as his spine curved a bit more, his black undershirt now cinched around his waist, his sides beginning to show hints of curves.

KNOCK KNOCK

"Eh?"

Shirogane looked to the door, unsure who was knocking. There were no major events coming up and today it was just him and Ishigami squirreling away the last few budgeting details. Ishigami was the one to casually ask, "Who is it?"

"I'm having trouble with Nagisa!"

There was a pause, Ishigami stepping back and pointing his fingers at the door, mumbling out a curse, "Die you stupid girlfriend having shit! Become a jealous loser! Lose your dick shitbag!"

"Is that really necessary?"

Ishigami shrugged, opening the door and losing his obvious hostility as he let Tsubasa in. He hadn't interacted with him much beyond shit talking behind his back, so the lack of height wasn't immediately obvious, though he did give a side glance to the line on his undershirt, the black fabric coiling tighter before his eyes. Probably just his eyes playing tricks after grinding all night in Genshin.

For some reason the sight of Yu made Tsubasa feel comforted, even if he generally only talked to Shiro- to Miyuki usually. He tried to gather his thoughts, unsure why this was even such an issue, feeling awkward and stupid with a great yawning pit in his stomach that felt liable to eat him alive. Instead it suckled on his sides, his toned core losing its strength bit by bit, rumbling slightly as his sides continued to pull in to elegant curves, the black fit line of the girl's uniform making a full circle as it teased his navel, slendering the divot while pulling his spine down into a cute arch. His pants were baggy on him, but it didn't matter in his sitting position, and besides they were slowly crawling up his stomach. It almost felt like a hug when they squeezed over his changing undershirt, comforting him as he sighed out, "I think Nagisa scares me no- KFF KFF!"

He was interrupted by a sudden dryness in his throat. He held out a hand, unaware the nails were extending, clear gloss cutifying the cuticles as he waited for his tea.

"Er, what are you-"

"Tea! You usuall- KFF KFF serve me tea!"

Shirogane was unsure what Tsubasa usually drank, the electric kettle always on so he just had to pour the water, giving him what they usually served Maki and trying to remember if they ever served him tea before. Ishigami on the other hand was glaring at Tsubasa's fingers, growing increasingly confused. There was that high crack in his voice a second ago, but Ishigami had a knack for spotting changes in fingers, largely from his own incessant upkeep for gaming. There was something weird happening, the pretty boy's clenched fingers slimming before his eyes, his palms receding into themselves as they turned familiarly dainty. He really must have stayed up late, is what Ishigami would have said if Tsubasa's white overshirt didn't suddenly shed its sleeves, coiling into cuffs that pulled on his black undershirt. Or was that a... dress?

"P-President?!"

"Eh what's wrong Ishigami?"

He had that tone like when he had pissed off Kaguya in the early days, complete horror and confusion, Shirogane wondering what could be causing it up till he turned, stunned to see Tsubasa wriggling in discomfort as his sleeves spread down, his white shirt melting into the black... what was he even wearing? Out of pure habit he casually set the tea down, both him and Ishigami staring wide eyed as the white cuffs slid to the base of his palms, his arms squeezed by the far too small dress top, a gurgled moan accompanying the sudden loss of muscle as his shoulders scrunched into rounded ends that made the two onlookers wince. In one elegant motion, Tsubasa grabbed the tea cup and downed it, unaware his pinky was extended, giving a pleased sigh as the swallows melted his neck to swan like slimness, his plushed lips smacking happily as he cooed out, "Ahh~ much better. Now back to Nagisa."

"D-Did something happen to you Tsubasa? You're-"

"YES IT DID!"

His eyes were tearing up, flecks of purple in them as he started off annoyed, yet seemingly oblivious to the changes.

"She's scary! And I think she's almost t-taller than me... I don't know what happened, we were always friends right?!"

His chin popped at the word friends, rounding cutely as his teeth shrank, the purple spreading as more tears welled at the corners. He was growing more animated as it went on, whipping his head back and forth, making his bleached brown hair darken as it whipped, stray strands braiding themselves in the chaotic growth along the fringes.

"I-I mean she's always been kind of overbearing right? You seemed scared of her when she interrupted us at the cultural festival right?"

He just nodded, unsure how to even take in what he was seeing as Tsubasa's cheeks crumbled to cherubic points, his eyebrows jerking up and down in obvious distress as they shed to thin lines.

"It's bad enough that I have to hear about them being indecent all the time! Er, no I mean, ah why can't I remember who was doing what? Ah t-tell me she's indecent right? Nagisa is evil right?!"

Neither knew how to respond. Tsubasa's face was fully Makied at his point, his shirt reduced to the white collar of the girl's uniform, his wide purple eyes beautifully sculpted with mascara and eyeliner as he held out the tea cup again expectantly. Ishigami grabbed the kettle, trying his best to probe the changing boy.

"Y-Yeah she sucks! But you were talking about the cultural festival. Weren't you there with Nagisa? I mean, I don't like most normies flaunting their girlfriends around, but she is your girlfriend... right Tsubasa-Kun?"

He was hoping it'd jolt him out of... whatever the fuck was happening, but instead at the mention of his name, a bright red blush prickled his cheeks, Tsubaki shifting about back and forth with an embarrassed look as the legs of his pants merges, flaring out to the skirted end of his new uniform.

"I-I mean of course we were lewd together. Nagisa kiss- I mean me watching her kiss mysel- Tsubasa. I mean I am pretty cool right?"

Tsubaki felt warm, gulping down another cup of tea, starting to feel horny as the gulps spilled down his dropped neckline, swelling under his nipples. Wh-Why was he getting so worked up at the thought of himself? Yeah he was pretty cool a-and handsome and his hair smelled nice, but... mmm~ yeah he was kind of great.

"Tsubasa... y-yeah I need to have more confidence! Otherwise I'll just k-keep losing out to other people. B-But Nagisa makes my heart race so I don't..."

He gave a cute moan, clutching his chest as it swelled more, the love in his heart thumping, making each beat tremble his breasts as they continued to surge.

"Mmm~ y-yeah if I was more like Tsubahhsa, hehe. Um um ayyyyeee~ think I n-need to-"

His uniform had a clear tent, tiny moans continuing to slip out as he finished his tea, his chest a perky, firm b cup as he moaned, his cheeks cherry red as he kept squeezing his cock between his thighs.

"Thank you Yu and Miyuki! B-But I need some alone time now!"

There was a bit of silence as she left, Miyuki staring at Ishigami.

"You won't curse me like that if I get a girlfriend would you?!"

"THAT WASN'T ME! IF IT WAS HALF THE GUYS WOULD BE GIRLS ALREADY! I WOULDN'T-"

Ishigami's eyes dulled for a second, looking around the room.

"Wait what were we worked up about?"

"Maki came in with her usual complaints about Nagisa."

"Huh..."

And they went on with their day as if nothing happened.

For Subaki, he couldn't just ignore the new sensations swirling inside, his cock trembling the more he thought of it as "Tsubasa's cock" in the third person, picking up his phone to call Nagisa for some plesure relief only to pause, his contacts different, the chauffeur that popped up who he hit instead as he realized he couldn't do something l-like THAT at school. He made it explicitly clear that this was an emergency as he hopped into the cushioned leather seats, using a hand to muffle himself as the black limo began a speedy drive to the Shijo residence.

It was torture, Subaki struggling to hold in as the smooth ride still had bumps, his ass gaining the same cushion as the seats as it bounced up and down, fantasies of Tsubasa spanking her- h-him leaving an embarrassing strand of drool from the corner of his mouth, his smooth thighs cradling his cock as they teased it. Each bump made their rubbing grip turn him on further, his sighs accented with cutesy moans as he squeezed his cock between pillowy flesh, going from desire to a need as he had to stop himself from cumming in his car, knowing he'd never live it down if word got out.

When the car finally landed, he gracelessly waddled out, teasing and suppressing his lust the best he could, his steps shrinking as his sporty calves shrunk into curved twigs, his shoes long since shifted to Mary Janes as he clacked his way into the house. It seemed to take forever to get to his bedroom, clenching his fists in frustration, bits of cum coating his waddling thighs as the rod gave a twitch. Someone was in there already, but he couldn't hold it back any more, squealing out, "I-I'm sorry sis I n-need to do something indecent!"

Maki was currently trying to sulk in private, making it clear to everyone that she needed some time on her own. Of all the people to barge in, the last she expected was another her sporting a massive cock and panting like a desperate animal ready to attack. It was only when she saw his bag fall to the floor, the last signs of Tsubasa existing tumbling out mid change, that she was able to make a guess, looking at the trashed trinket that she had used, horrified to see it hadn't been a rip off after all.

"HYAAA AHH YESSS~! TSUUUUBAHHSAHH~!"

Where Maki was horrified, Subaki was entering nirvana, slipping out of his now stained uniform and lovingly stroking the throbbing rod inexplicably stuck between his legs. He had enough memories to know it was his cock, yet the Maki majority wasn't bothered in the slightest. Instead she was a giggling, cumming mess, feeling the stuff of her fantasies drill into her body as she eased it into her body.

"AHH AHH IT'S SO BIIIIG TSUBASAAAAH~! AHHH H-HAARRDERR YESSS~!"

Her strokes were getting faster, her palm shoving harder as she felt more of his shaft melt into her forming pussy, the lovesick girl desperate to have her love inside as deep as possible.

Maki was speechless at the spectacle, her face a deep crimson at the lewd sight, yet more than anything she felt... jealous?

"I-Is his manhood th-that good?"

Her twin squealed as she jabbed into her balls, thick spurts rocketing out the half submerged shaft as the bumps retreated.

"YESSSSSS~! IT'S HNNGH E-EVERYTHIIIING I EVER DR-HEEEMED O-O-OOOOF! SOOOO GOOOOD!EVERY INCH OF MY PUSSY IS- GYAAAA~!"

She could barely think, reality rewriting in her head as her lust for her former self peaked, her cock barely able to resist her forceful shoves.

Now Maki was drooling, the thirst strong as she watched her crush turn into her, another her being fucked out of her mind by Tsubasa's dick. Was it wrong to try and take advantage of this? I-If Nagisa could be lewd so often, then why couldn't she?! Oh crap there was barely any left she had to ask quick!

"Ah T-Tsubasa before it's gone c-could we maybe share your c-cock?"

It took all her effort to even ask, and she was completely ignored, only able to watch as her crush rolled over and thrust into his hands, grinding the thick shaft in with the loudest, lewdest scream she'd ever heard as a final sickening POP erupted over her bedspread, another her giggling before the pleasure petered off, looking around confused for a second.

"Ooh~ T-Tsubasaa, Tsugisaaa~ Naaagis- Wh-Why are you here sis? G-Get out!"

And thus Maki was kicked out of her own room, one of the spare guest rooms in their mansion filled as if always being hers as she was left shaking in jealous rage at her new twin's luck at getting fucked by her crush.

------

"Oh you should feel her technique sis. Her tongue, her fingers? Why, she's so skilled it'd make you think you were masturbating wrong your whole life. And my word the daring of her!"

It had only been a week since the change, and Maki was being driven insane. She was the only one who remembered who Subaki used to be, the world rewritten to have her in Tsubasa's place. When she had found out that Subaki and Nagisa were still a couple in this world, she had raised an eyebrow, but she at least thought it'd be the end of her jealousy. It had to be easier seeing her twin with her best friend than her crush right? But Subaki couldn't keep quiet about their love life, Maki hearing them occasionally when they did a "study date" the squeaking of their mattress mixed with orgasmic cries, and Subaki couldn't help herself with the details.

"You should feel how she strokes me. Honestly she's such a perv she'd probably enjoy having you in there too. I mean not that my prudish sister would ever want that. You're too busy being a dirty siscon right?"

Oh and when she had asked to join in, she wasn't being allowed to live that down, Maki unsure what the context had been edited to, but she just denied it with increasingly flustered annoyance. It wasn't fair! She had to keep hearing them be horny, keep hearing about how amazing Nagisa was, and last night when they had been really loud, Maki had gotten horny and and-

Oh no, w-was she starting to fall for Nagisa? No! Nagisa was a friend! A good friend! A s-sexy, lewd, bisexual... Fuuuuuuuuuck!

And so Maki's torment continued.
