(Now with illustration!)
Evening, that sa day.
"Over there~!"
"Got it!"
In the indoor pool beneath the Hyoudou residence.
I bat the ball Miyu threw toward Alice.
After club activities, we'd all gathered to unwind with water polo.
Everyone living here was present, plus Gasper, and even Griselda-san had co over (to check on Xenovia).
"Glub…! I can't swimmmmm!"
The one screaming is Gasper—slipping and nearly drowning again.
Playing water polo: , Miyu, Alice, Koneko-chan, Ravel, Kuroka, Le Fay, Diarmuid, and Gasper.
"Gasper! Be a man and swim!"
"I caaaan't! Vampires hate waterrrrr!"
He says that, but you were just playing water polo! You were moving in the water just fine!
"You're only half-vampire! And your feet touch the bottom!"
"Oh… right."
He finally stands.
I thought he'd gotten manlier… but he's wearing a won's one-piece swimsuit!
"Ufufu~ Gya-kun is so cute-nya ♪"
Kuroka pats his head, her ridiculously skimpy bikini making her breasts bounce wildly with every move.
Even in Shirone mode, Koneko-chan proves the Nekomata sisters have sinful bodies.
Diarmuid's figure is incredible too—huge breasts (not quite Kuroka-level), perfect proportions. Her purple bikini matches her hair and is pure eye candy.
Of course Miyu, Alice, Ravel, Le Fay, and Koneko-chan all look adorable and stunning in their swimsuits.
Earlier Miyu had a wardrobe malfunction—total nip slip. I stared way too hard.
"You see naked all the ti, right?"
"Yeah, but… accidental reveals hit different."
"They do?"
"They do."
Miyu tilts her head with a little "hm?"
Nude is great, costus are great, but accidental wardrobe malfunctions? Chef's kiss. Only n understand.
But wait—
"Accidental reveals are the best! I get it, Issei! Co on, everyone move more—pop pop pop!"
Ignis, beer in hand on the poolside, totally drunk and cheering.
Knew she'd get it. Total perv. Even more than .
Then she continues—
"Issei, you pop too! Now's your chance!"
What joy is there in a guy's wardrobe malfunction!?
…Though right now, that retort would be inappropriate.
Miyu suddenly hugs my waist.
"Mmm~ So cute! Let's stay like this a while, okay… big sister ♪"
Let explain my current situation.
I'm not wearing n's swim trunks.
I'm in a won's bikini.
Hair down to my waist, bangs almost covering my eyes.
Soft, rounded body; breasts that jiggle with every move.
Tiny waist, seductive hips and thighs.
Long, slender fingers—every part screams "girl."
You get it, right?
I'm fully gender-bent again.
I look up at the ceiling.
"WHY DOES THIS KEEP HAPPENING TO EEEEEEEEEEE!?"
[Illustration]
A little earlier.
After club, we'd co ho and were relaxing.
I'd holed up in my room—actually one whole spare room I'd claid as my personal plastic-model workshop—working on a kit.
I'd just bought a display case, so I had space to show off completed models.
Right now I was airbrushing parts I'd gotten from Azazel-sensei.
Careful not to over-spray…
"Nice. Ca out perfect."
No uneven spots, perfect prir.
Heh heh… 1/60 scale, twenty thousand yen.
This ti I'm even adding LEDs—gonna be flawless.
Grinning to myself, soone enters.
Miyu.
"Found you, bro— Whoa, thinner sll…"
"Bad? Did it build up?"
"Totally. Ventilate or your brain'll go boom."
"I've always wondered… what exactly does 'brain go boom' an?"
Guess it did get stuffy.
Windows open, paint booth fan running… but after hours you stop noticing.
Miyu flicks her finger; a tiny magic circle appears in the corner and starts cycling fresh air.
"All better!"
"Thanks. I made good progress anyway."
Rows of beautifully painted parts. I'd been at it since getting ho.
Need to let them dry fully.
"Ugh… sitting this long is murder on the back. Legs are numb too."
"Then co to the pool with ! I bought a new swimsuit."
"In this season?"
"We have an indoor heated pool, silly."
Fair.
But then she drops the bomb.
"Try it on. It'll look perfect on you."
"…?"
We pick out swimsuits together sotis, but her buying one for without telling ?
Wouldn't the clerk give her weird looks for buying n's trunks as a girl?
Suspicion rising, Miyu smiles brightly.
"Yep, for you. You'll look super cute."
Cute…?
For a guy…?
Hold on.
That smile.
That scheming, adorable smile.
No way—
No way——!
"Here it is! You'll look absolutely adorable! Big… sister!"
From nowhere she produces—a sexy red bikini!
"Wait— That's won's! You expect to wear that!?"
"Exactly! Gender-bent big brother will be perfect! Look, I even brought the sex-change gun!"
"Where'd you find that!? I hid it properly!"
"I'm not soone who can't read big brother's thought patterns!"
"As expected of my little sister! But your brother won't fall for the sa trick twice!"
"Wanna bet? Hyah!"
She leaps, flying straight at !
If she were an enemy I'd dodge, but this is Miyu—I instinctively catch her full-on!
"Gotcha ♪ I knew big brother would catch !"
"You planned this!?"
Damn it!
She exploited my weakness!
Ahh… Miyu's so soft and fluffy… adorable…
"Ufufu ♪ Ti for big sis to go swimming!"
And that's how it happened.
Shot point-blank while being hugged—I couldn't do a thing.
Turned into a girl, completely at Miyu's rcy, forced into the bikini she and Mom apparently picked out together.
"Perfect fit ♪ Mom's eye is scary good—she guessed your girl asurents from that one incident."
I was speechless.
Mom sized up gender-bent perfectly… and tead up with Miyu to buy this?!
Terrifying.
What will beco of ?
Even if I hide the gun, Miyu finds it. Even if I destroy it, Azazel-sensei just makes a new one on request.
Am I dood to be their dress-up doll forever…?
"So cuuuute~ Big sis is adorable. And those boobs are huge~"
"I'm a guy… touching my own boobs feels weird…"
"But right now you're a total beauty no matter who looks."
"Hyah!?"
Sudden tickling makes jump; I let out the cutest scream imaginable.
Miyu was tickling my sides.
"See? Right now big brother is a cute big sister!"
"Why are you so hyper!? Hyah—s-stop, that tickles—take this!"
I grab her hands, slip behind, and tickle back!
Eye for an eye!
Double payback!
"Hyah! F-Funyaa! B-Big sis, there—nyaaa!"
"Who's your big sis!?"
"Unyaa~ Big sis is mad~!"
Miyu escapes into the water!
Like I'd let her get away!
I dive after her!
Thus began sibling underwater chase.
Miyu's a wizard type, but her physical ability far exceeds normal devils—fruits of daily training.
But!
When it cos to raw athleticism, I'm the specialist!
She can't beat !
Splashing wildly, I close the gap with ferocious crawl strokes and capture her!
"Gotcha."
"E-Eh…? Big sis? Your face is scary…"
"Just imagination. See? I'm smiling."
I grin sweetly.
Brief silence…
"Naughty Miyu gets the tickle hell punishnt!"
"Nyaa~ There—fuaah! N-No mooore~!"
"Hah… hah… haa… nngh… you squeezed so much…"
Miyu twitching in my arms, princess-carry style.
I went pretty hard.
Grabbed boobs and butt plenty (over the swimsuit).
Her reactions were too cute—I got carried away.
But a little sister who plays with her brother's body deserves it.
I lay the sweetly panting Miyu on a poolside lounge chair and sit beside her.
In the pool, everyone else has resud water polo without us.
"Wahh! Drowning againnn!"
Gasper fell again.
He definitely needs swimming lessons.
"Girl-mode Issei-kun really is cute! The gap from usual makes it even better!"
Reyna hugs from behind.
…Why is my gender-bent form so universally loved?
Dress-up doll factor?
The gap from male to female?
Alice and Koneko-chan hate it though… mostly the breast part.
Anyway, Reyna's boobs are squishing my head right now—heaven.
I spot the Church Trio talking seriously in one corner—probably election strategy.
"Xenovia has changed."
Soone speaks beside .
I turn—Griselda-san in a bikini!
Normally always in nun clothes, so I never noticed—she's ridiculously stacked!
The ultimate pure maiden in a bikini… and emphasizing those breasts so much!
Dazzling!
Griselda-san sits next to .
"…'Slashing Princess.' That was Xenovia's nickna as a warrior. You know it, right, Issei-san?"
"Yes."
Wielding Excalibur and Durandal, she rcilessly cut down devils, fallen angels, vampires, monsters—enemies of the Church.
Her cold, unreadable personality earned her the mocking title "Slashing Princess."
"She was a handful. Sa facility, so I was chosen as her caretaker. Everything she did was sloppy; teaching even basic lady-like behavior was exhausting."
"Ahaha… I can imagine."
"It's not funny. She really was a problem child."
Yet Griselda-san's face is warm, her tone like an older sister talking about her little sister.
"She finally started acting her age after eting warrior Irina."
"Irina was the only one who could partner with her, right?"
"Yes. Only Irina could adapt to her ideology and fighting style. I'm truly grateful to Irina. Without her by Xenovia's side, the current Xenovia wouldn't exist… I nearly fainted when I heard she beca a devil, but seeing her confused, laughing, surrounded by warm friends… I think her choice was right."
In Griselda-san's eyes: the Church Trio laughing together—heartwarming.
"I heard she's running for student council president."
"Yeah, giving it her all. Staying after school with friends for strategy etings."
"She must really love school now."
Griselda-san is genuinely overjoyed at Xenovia's growth.
She's strict normally, but thinks of her like a real little sister.
She turns serious.
"Issei-san, please continue looking after her."
"Of course. She's precious family to too."
"Ufufu. I'm glad the man she fell for is you… Since you took her purity, treasure her properly, okay?"
"Y-Yes ma'am!"
G-Griselda-saaan!
Your eyes aren't smiling!
Last New Year's she summoned —Xenovia skipped too many details and it got ssy!
…Asia cleared things up, thank god.
Anyway!
"I'll treasure Xenovia! I'll make her happy!"
From across the pool—
"Issei! Say it again! One more ti!"
"You heard that!? Geez—I'll make you happy! First win that election! I'll support you 100%!"
"UWOOOOOH! I'm fired up! I'll beco student council president!"
Xenovia roars, aura blazing, fire in her eyes!
Even Griselda-san can only give a wry smile.
"She never changes… Oh, Issei-san."
"Yes?"
"If you two end up together… does that make your big sister-in-law?"
"I… guess so?"
Indeed—if I marry Xenovia, Griselda-san becos family…
She thinks for a mont, then murmurs:
"…Will I get a niece? Or a nephew?"
"Eh— W-What was that?"
"N-Nothing!"
"…Okay?"
She's… totally expecting grandkids already, isn't she?
No way, right?
"But you know…"
Griselda-san looks up and down.
"When the current you says 'I'll make her happy'… it feels weird."
"Please don't say that."
Right.
I'm a girl right now.
I cried a little inside.
And that's how we got the gender-bent Issei (swimsuit ver.) illustration! This ti I focused on Issei's scream rather than pure cuteness (lol). How was it?
If there are more requests, I'll draw again!
