Rin Ito: [Whose bright idea was that?]
Nijika: [Bocchi.]
Kita: [Bocchi.]
Ryo: [Bocchi.]
Rin Ito: [....]
Nijika had filled Rin in on everything that happened at Starry.
Even though Bocchi and the others had gone through similar things before, Rin had only intended for the MyGO girls to learn some instruments and for Tomori to get some advice from Bocchi.
He never expected it to get that intense...
He could understand Tomori's obsession with a "lifetime band," but he didn't expect Anon and Rana to play along.
Truly the "Succubi of MyGO."
If he had known, he would have gone there himself!
But it couldn't be helped...
Ever since Rin told Shinju that her custom lingerie and uniform had arrived, she had been vibrating with excitement.
He couldn't exactly push back the date.
Early that morning, Shinju arrived at the hotel with her "little tail" firmly in place.
After two weeks of training, her rear had completely adapted to the plug; she could even do light exercises in P.E. class without an issue.
"Big Brother~ Is the lingerie ready?"
The moment she stepped into the room, Shinju couldn't contain her thrill.
Rin found it quite amusing to see a girl who was nearly taller than him making such adorable, childish expressions.
"It's been ready." Rin pointed to the pile of items on the table.
Beyond the uniform and underwear, he had bought quite a few accessories based on Marin and Orie's recommendations.
"Strip down first. This gear is a nightmare to put on."
"Mmm!" Shinju nodded vigorously.
For the sake of her first-ever cosplay, she unhesitatingly shed her dress printed with cute cherries.
The cups of her bra were large enough to cover her older sister Juju's entire face.
Rin noticed a fine layer of sweat on her skin, a testament to how excited she was on the way here.
She removed her dress and bra, then unfastened the adult diaper she used to absorb her leaks.
Then, with practiced ease, she knelt on the sofa in the "OR2" position to allow Rin to finish her daily butt-training.
Before he even removed the chastity belt, Rin saw that the edges were damp.
According to the system logs, Shinju spent 80% of her waking hours in a state of "mild arousal," while Juju was at a staggering 95%!
Juju even reached a forced electric climax once a day on average, and twice on weekends.
Removing the belt, Rin pulled out the sticky tail plug.
As it came out, he almost heard a wet 'Pop!'.
Under Rin's gaze, the stretched opening quickly puckered back into a tight circle.
"This level of tightness is perfect. The elasticity is great."
"Ehehe~"
Even though the compliment was about her ass, Shinju was glowing.
After using wet wipes to clean her sticky thighs, Rin pulled the chest binder out of its packaging.
A binder is different from a standard wired bra; it looks like a high-compression sports vest.
A normal girl could just pull it on, but Shinju was different.
This thing had to suppress the terrifying monsters that were her G-cups!
"Lift your breasts up. I need to wipe the sweat off first. It'll be miserable if you put it on while damp."
"Okay~"
She lifted her arms and hiked up her heavy G-cups. Rin could clearly see the moisture trapped beneath.
With no ventilation, sweat was inevitable.
Rin wiped her down with pure water wipes, dried her with tissues, and then applied a generous amount of antiperspirant.
"Binders are tight and make you sweat more. This will make it a bit more comfortable."
"I also have nipple covers... otherwise, the friction will be agonizing."
"Big Brother, you're amazing!" Shinju's eyes widened. She hadn't expected him to be so professional!
After applying the spray and the covers to her sensitive tips, Rin picked up the vest-like binder.
It looked like a normal tank top, but the application was different.
He rolled the bottom and top edges toward the center, much like rolling a stocking.
Then, she had to step into it and pull it up like a skirt.
"Lift your legs."
Once the ring of fabric reached her waist, he began to unroll it upward.
The bottom didn't matter, but the top edge—the part that provided the compression—was vital.
"Tell me if it feels too tight, painful, or if you can't breathe. Comfort and fit are the priorities."
"O-Okay!"
Wearing such a garment for the first time, Shinju instinctively swallowed.
Rin had no time to admire her massive curves now; he carefully gripped the edges and pulled the fabric up.
As he moved upward, he had to manually shift her breasts, tucking them into the armpits and flattening them toward the sides.
"Stand straight... don't hold your breath, just relax naturally."
"O-Okay."
Getting it on was only half the battle. The most important part was adjusting the silhouette to look natural and symmetrical.
Being his first time, Rin spent over an hour meticulously shifting her flesh until he finally clicked the front clasps shut.
"Phew..." Rin was drenched in sweat by the time he finished. "How does it feel? Move around a bit. Any numbness or chest pain?"
"None at all! Big Brother, you're incredible!"
Shinju ran to the full-length mirror to admire her bound self.
From the front, her previous silhouette was gone. Her massive chest now looked like a pair of well-developed pectoral muscles.
In men's clothing, she would look like a buff guy; her female curves had vanished.
Of course, mountains that big don't disappear into thin air. From the side, there was still a noticeable bulge.
But for a concealment job, this was as good as it got.
The rest was easy.
To hide the remaining "pec" bulk, Rin gave her shoulder pads to broaden her frame and make her look more masculine.
He put on her hairnet and a black wig, giving it a quick trim before starting the makeup.
Shinju was used to doing Juju's makeup, but this was her first time doing such a detailed job on herself.
Cosplay looks better in photos than in person not just because of Photoshop, but because of heavy makeup designed for the camera.
In person, it could look a bit over the top.
Aside from complex armor, putting on the clothes is usually the simplest step.
With the shoulder pads, dress shirt, and trousers on, the transformation was complete.
"This... is Soma."
Looking in the mirror, Shinju held her breath.
Even with the heavy makeup, her facial structure and eyes still hinted at her femininity.
If a man actually looked like this, Rin could only comment: [Can a man really be this beautiful?]
Still, the level of reproduction was stunning.
"Not bad, right? Your sister is going to have a heart attack when she sees this."
"Mmm!" Shinju nodded hard. "Big Brother, your turn! I'll do your makeup!"
Compared to Shinju, Rin's Sakuya cosplay was simple.
Hairnet, grey wig, light makeup, and a pre-sized uniform.
While Shinju took two hours, Rin was ready in twenty minutes.
"It's like Soma-niisan and Sakuya-niisan walked right out of the screen!"
Shinju grabbed her Panasonic FZ2500 and started snapping photos of Rin, expertly directing him into various poses.
Used to being behind the camera for her sister, it took a reminder from Rin for her to realize she was a cosplayer today too.
She eventually handed the camera over.
Rin wasn't an expert photographer. Shinju set the parameters, the lighting, and the poses. Rin was just the tool that pressed the shutter.
"Big Brother... let's use the timer for some duo shots~"
Since there was no third person, their angles were limited, but Shinju was over the moon just to be in frame with Rin.
In the anime, while never explicit, it was heavily implied that Sakuya and Soma were a couple.
That was why Shion's sister turned into a villain.
Since they were "lovers," they had to take some intimate photos—like the classic chin-lift.
Rin struggled to keep a straight face because his Sakuya was the "bottom" in this dynamic.
It resulted in Shinju's Soma lifting Rin's chin.
With her excellent makeup skills and her fingertips on his jaw, Rin almost broke character.
He felt like he was about to be kissed by a "beautiful man."
"Hiss... Stop, stop, stop... No, I can't. Let me breathe for a second."
"Pfft..." Shinju giggled behind her hand.
"Earlier you said a boy cosplayer has to use his ass. Does Big Brother still want my ass now?"
"..." To be honest, Rin only said that to tease her and justify her anal training.
The "boomerang" of his own words had hit him right in the face.
"Ahem... let's wait until you're back in a dress." Rin cleared his throat awkwardly and pulled up the photos she had sent him earlier.
"This version of Shinju is much cuter."
"Big Brother! D-Don't look at those!!"
Seeing the photo of her own ass with a tail plug hanging out, Shinju's face turned scarlet.
She had taken them herself, but looking at them now... they were so depraved.
My ass is actually that lewd.
No wonder Big Brother loves it so much... Hehe~
"Then..." Shinju bit her lip, her eyes sparkling with expectation as she winked at Rin.
"Does Big Brother want to eat my ass right now?"
If it were a normal day, Rin would have devoured her on the spot. But now...
"Pfft... Cough cough cough." Seeing her expression, Rin choked on his spit.
"Don't... don't say things like that with Soma's face. Take your photos first. You spent all this time on makeup; get your shots before we do anything else."
"Okay~"
Rin took several deep breaths to stabilize his resolve.
It wasn't that he thought he was turning gay; he just didn't want to think about "Soma's" face while he was kissing her.
