Chapter 25: The Transformation Begins: A Sister’s New Wardrobe

“Huh?”

Chajingyuan looked bewildered, as if the notion were utterly preposterous.

“Didn’t you take the wrong one? That bra is clearly yours; why would you give it to me? I’m your older brother~”

“Older brother, my foot! Who was just moments ago, with an innocent little sister’s face, pleading and begging? And who was speaking as if they weren’t a little girl at all? Who are you trying to fool?”

“Ugh?! W-well… it seems that way…”

“Besides, if I were still wearing such a small bra, wouldn’t I be mad? Use your brain, you dimwitted older brother. There’s no way I could fit into this size now.”

“Uh, right.”

Chajingyuan, as if waking from a dream, suddenly grasped the obvious.

“But… I didn’t actually check the size back then. Hey, wait a minute? If that’s the case, where did you get all these small-sized undergarments?”

“When I first moved out, Mom and Dad packed all of them and just dumped them on me. As for this particular one… if I recall correctly, it was during the second semester of junior high.

My previous two bras were worn out, and I bought this one, only to realize shortly after that I already couldn’t fit into a C-cup anymore, so it just happened that I didn’t wear it much.”

“…”

“It should still be relatively new, right~?? Assuming the underwire and fibers haven’t aged too badly over time, since I haven’t studied material chemistry or anything… Anyway, older brother, why don’t you try it on first?”

“No, wait, wait a minute? How much did you just say it was, C or something?”

“C-cup, what’s wrong?”

“You, you, you…”

Chajingyuan’s expression instantly turned as if she had seen a ghost.

“A C-cup, in the second semester of junior high??”

“Don’t give me that skeptical look. The three of you barely even looked at me during that period, did you? Could you possibly know my ‘developmental function’ better than I do?”

“Uh… so, you, already a C-cup in junior high, then…”

“By the way, my current size is an H-cup. So stop staring at my buttons with that ‘doubting-life’ expression, and worry about yourself first~”

Chahuayuan shot her an exasperated look, plucked a caviar sushi from the computer desk, and unceremoniously shoved it into her older sister’s mouth.

Then, she rose to retrieve the undergarments that had been casually hung on the curtain rod earlier.

“…First, quickly eat your late-night snack. After you’re done, I’ll help you try it on. If it doesn’t fit, there’s still time to quickly buy you a few sets you like tomorrow.”

“Uh, this.”

Gazing at the delicate floral patterns and the curved fabric imbued with a distinctly girlish charm, Chajingyuan swallowed the sushi with effort, her face clouding with reluctance.

“Um, can I… can I not try it on?”

“No.”

Chahuayuan brusquely refused Chajingyuan, then shoved a second piece of sushi into her mouth.

Under Chahuayuan’s firm supervision, they quickly devoured the entire late-night snack.

Immediately after, as if by natural progression, Chajingyuan found herself pinned against the corner of the bed by her younger sister.

Chajingyuan’s face was etched with terror, yet she clung to her dignity, making one final plea before being “forced to wear girl’s undergarments”:

“At least, at least… could you please, please, please not touch me anymore? I mean! Can I, can I put them on myself?!?!!”

“Oh…?”

Facing her aggrieved, petite, and pitiful older sister, Chahuayuan tentatively agreed.

To avoid adding too much psychological pressure on Chajingyuan, Chahuayuan turned her back, no longer watching her sister’s movements.

She cleaned up the remnants of their late-night snack while idly listening to the sounds of her older sister struggling with the undergarments.

“Ugh, so troublesome… so hard to put on…”

Rustle, rustle.

“It’s so unsettling; I already feel uncomfortable before I’ve even put it on properly…”

Click… click…

“Ugh, I’ve… I’ve put it on. It feels awful.”

Chajingyuan let out a long, breathless sigh, and Chahuayuan, seizing the moment, turned back around.

The floral undergarment hung askew on Chajingyuan’s upper body, at a profoundly awkward angle.

“Mmm…”

“That’s why I said I didn’t want to wear it in the first place.”

Chajingyuan grumbled, meeting Chahuayuan’s gaze with palpable annoyance.

“This thing, no matter how I wear it, feels terrible. It’s like my whole body is being constricted and distorted! With my figure, there’s no need to torture me with this inhumane contraption. It’s utterly chaotic.”

“Mmm, I’m star—”

“What are you still staring at? I just told you personally that it’s uncomfortable; don’t you believe me?”

“Didn’t you fasten the back clasp crookedly?”

“Uh.”

Chajingyuan’s small face, initially a canvas of shame, vexation, and protest, instantly stiffened like a freshly fired red brick from the kiln, her protests stifled by Chahuayuan’s observation.

When Chajingyuan turned to confirm, sure enough, the steel hook was crookedly fastened to the outermost side of the deepest row. Chahuayuan let out a long sigh, then solicitously placed her hands on her older sister’s shoulders.

“Alright, older sister, stop trying to be tough. There’s nothing to be ashamed of; I’ll teach you how to wear it.”

“Ugh, how did it come to this…”

Chajingyuan resisted both the intimacy of being touched by someone else and the unsettling challenge to her gender identity posed by the girl’s undergarments.

At this very moment, as her younger sister held the bra in one hand and reached around her chest with the other, both of these defenses utterly crumbled.

“Alright, older sister, just stand still for a moment.

Before putting on the bra, first make sure to stretch out the skin on your upper body, gather the flesh around your armpits, and the front of your chest too, so that it doesn’t bunch up and feel uncomfortable later.

First, use your hands to lift it up…”

“Eek—!!”

“You should understand this principle, right? It’s like how I heard boys adjust their ‘egg path’ before putting on underwear… you can think of this as adjusting your ‘milk path’?”

“There’s, there’s no such thing as an ‘egg path’!”

“Oh, whatever. Anyway, just lift your hands, slip it on, see? If you adjust it beforehand like this, when you put it on, you can tuck all your breasts in, and they won’t hang uncomfortably. Won’t that be much more comfortable?”

“Mmm…”

“Then for the back clasps, your figure is so slender, it shouldn’t actually be too difficult to fasten. Both hands level, yes, just like that…

Then first align and fasten the topmost clasp. For you, the second row is more suitable, mm-hmm, that’s right… Then slowly fasten the remaining two… OK!”

With the task complete, Chahuayuan happily turned Chajingyuan back to face her.

“How is it, older sister? Isn’t it much easier to wear this way? And quite comfortable, not so annoying, right?”

“Mmm, mmm…”

Chajingyuan blinked her eyes in a daze.

Her hands gestured thoughtfully in front of her chest, and indeed, a hint of surprise flickered in her gaze.

“It does seem much more comfortable? But…”

“Alright, no ‘buts’. Since you’ve already put on the bra, even though it’s late, let’s put on the underwear and outer clothing too and see!”

“Hey, hey, hey? No, why are you being so pushy…”

“What do you mean ‘pushy’? You’ve already accepted the bra, and now you’re haggling over a little skirt. Come on, be good, let me help you put it on~—”

“Ugh, that’s true, but, but, but…”

Chajingyuan, offering a soft and powerless, merely symbolic resistance for a while, ultimately allowed her younger sister to help her don the underwear and outer clothing.

“Older sister, but seriously, your butt really feels quite nice, super bouncy and elastic.”

“So you really are a perverted younger sister, aren’t you!”

“Oh, that’s not important.”

Chahuayuan slung an arm around Chajingyuan’s shoulders.

“Older sister, this outfit seems to suit you quite well. I’ll take you to look in the mirror… Ah, you don’t have a full-length mirror in your room, let’s go take a look in the living room.”

“Mmm…”

Half-coerced and half-willing, Chajingyuan was led by Chahuayuan to the living room corner, where she stood awkwardly before the full-length mirror beside the refrigerator.

“Lights on, look, ta-da!”

The room brightened.

Reflected in the mirror, and in Chajingyuan’s astonished eyes, was a petite, exquisite girl.

She wore a high-waisted dress with a delicate lotus-leaf collar, its pristine white chiffon fabric adorned with vibrant, rosy candy colors. Her puffed sleeves were embellished with charming ribbons and bows.

A cascade of voluminous, silver-blonde long hair shimmered brilliantly, appearing almost ethereal.

“…”

Chajingyuan’s eyes widened, transfixed.

She was clearly somewhat incredulous—could this adorable, beautiful girl truly be herself?
