A Perfect Fit

“I have PE during that Time, Nee-san.”

Natsume lifts her teacup off of her saucer, hiding half of her expression behind a sip. A few customers pass them by, old and new, exiting the establishment and taking their seats in the freed booths respectively. She gulps at a deliberate pace, taking quite long for the amount of liquid in the cup.

My, it seems her adorable junior is flustered. To only be able to come up with a half-assed excuse like that, when Wataru and her other Eccentrics know Natsume regularly ditches that class… It seems she has her work cut out for her.

When it becomes apparent Wataru will not comment during her drink, Natsume places her teacup back down with a clink, picking up her fork and slicing one of her small square cakes sitting on her plate. She lifts the triangular piece of chocolate and strawberry up to her mouth, chewing delicately.

Wataru smiles, placing a hand on their teapot’s lid and pouring a refill for Natsume, before taking a sip from her own teacup.

Natsume swallows, raising an eyebrow. “I hope that isn’t too disappointing.”

“Why would it be?” Cuh-link. “You’ve just confirmed that you’re free.”

Natsume narrows her eyes. “Wh- I said that I have Class! Shouldn’t upperclassmen be praising their juniors for staying in School, rather than encouraging them to be delinquents and go Shopping?”

“Fufu.” Wataru picks up her fork, swiping another corner off of Natsume’s cake. “Perhaps.” She twists it to hang upside down, letting the moist layers of sponge meet her tongue first. And after pressing her lips together, the fork emerges clean.

“So Then?”

Wataru swallows. “It can be argued that it’s also an upperclassman’s duty to nurture their juniors' development—on a case-by-case basis.” 

“What exactly would we be Developing,” Natsume asks, “if we were to go purchase Lingerie?”

“Many things!” Wataru sings, nearly knocking over their teapot in her grand gesture. “An eye for the artistry behind the garments, for one. But I’m more interested in the development of a persona that lingerie can engender.”

Natsume squints, cocking her head and cradling their teapot.

“Ah, to explain with words is quite difficult~ But if you were to accompany me, you could witness the effects firsthand. You possess the quality that would make it most wonderful to observe.”

“What sort… of Quality?”

Desiring larger breasts.

“Why, being my girlfriend, of course.” Wataru smiles. “Is it so wrong of me? To also wish for my love to adorn herself in pretty clothing?”

Natsume blushes, scooting the teapot back to its original place with a few fingers. “Not like you would get a good look at it outside of the Bedroom.”

“But that is the point.”

Natsume grows quiet again, waiting for her neesan to continue.

Wataru’s eyes drift to the side, trying to find her explanation. “That invisible aspect, I mean.” She quickly studies the other patrons of the establishment. “Everyone here, you and I included, give off an impression from their outward appearance. But. The layers beneath… How much does it affect the character of their actions—their thoughts, their attitudes, their self-perception?”

“With all due Respect, Wataru-neesan, I think it’s just Underwear,” Natsume sighs, picking up her fork again. “But… If I can help you with answering your Question…”

Wataru looks back to see a shy expression.

“Then I will meet you in one of the secret Passageways.”

“So you’ve never been here before, Natsume-chan?”

Wataru doesn’t need to ask to know. It’s already apparent from how she fidgets and stands a little more unsure than usual. She can guess her junior has never stepped foot in such a high-end lingerie shop before, and as a result, she feels out of her element; but to alleviate her anxiety, a chat is always a good distraction.

“Mommy always…” she mumbles. “I usually don’t go out of my way to come to places like This.”

“Shall we hold hands so you don’t get lost?”

“That doesn’t mean I’m a Child, you Know,” Natsume says, taking her hand anyway.

Wataru hums happily, leading the both of them past racks and displays of lacy and plain lingerie alike. But when Natsume slows her walk while they’re about to pass by a mannequin, Wataru turns her head back.

“Oh-” Natsume returns her gaze to the direction they’re walking. “Sorry, I was just Looking.”

“A large part of shopping is looking, dear.” Wataru unlinks their hands to take a closer look at the display. “What do you like about it?”

It’s a plain but elegant design. No frills, no lace, only a small white ribbon between the cups, centered on the gore. The small-busted mannequin looks adequately supported as well.

“It just caught my Eye. I guess the Simplicity, Maybe.”

“Hm~? It reminds me of what Eichi-chan wears when we change for practice.”

“On second Thought, I don’t like It.” Natsume walks away.

“Haha, hey, wait up!”

They peruse through a few more designs when a pattern emerges: something that accentuates the natural shape of the breast, and something that wouldn’t be too itchy to wear. The color doesn’t seem to matter, but Wataru thinks a vibrant red that matches her hair would be the best—but she is biased.

Once they do find the perfect design for Natsume, a bralette with triangular cups and a few additional straps that cross over the chest in an X-shape, Wataru suggests which color she should pick.

“Okay.” Natsume says, holding the red bra’s hanger.

“You’re not going to pick a few sister sizes in case it doesn’t fit?”

“Sister- Oh. Yeah,” Natsume glances at the number on the hanger’s neck, “Right.” She quickly grabs a band size two numbers above and below, placing it on the rack of her finger.

“Alright~ let’s go to the dressing room!”

“What about You, Nee-san?”

“We’re here for you today, silly.” Wataru grabs her hand again, guiding her. And in no time, they shuffle into an available room.

Click, click. Once Wataru closes the door behind her, Natsume shifts.

“Hm? Is something the matter?”

“I’m just a little- Embarrassed, I Guess.”

“I’ve seen you undress a few times now. Why the sudden shyness?”

“The context of the scene has Changed,” Natsume puts it into terms Wataru finds more familiar. “The actor requests her neesan to provide adequate privacy while she switches her costume Out.”

“If that is what the actor requires as accommodations.” Wataru inclines her head, turning around and closing her eyes.

There’s a beat of silence, and then she hears the sound of fabric rustling first, the squeakiness of metal on metal next, as Natsume hangs the bras on a peg on the wall, before there's more sounds of fabric moving against skin.

Wataru peeks open an eye, looking through the mirror Natsume neglected to account for, watching her take off her bra. Ah. it’s not one of the mature-looking designs she has seen on her, but a cozy sports bra—one that looks to be well-loved, and a hand-picked one from a mother, perhaps.

Wataru closes her eye before Natsume completes her turn, listening to one of the bras being taken off of its hanger, the snap, snap of fabric on skin that follows, and then another beat of silence.

“Well, I’m Finished.”

Wataru rotates herself to be in the presence of a goddess. 

She stares. The few strands of hair that overlap one of the cups is a near-perfect match in shade. It hugs her in a way that Wataru can imagine her doing her everyday tasks with ease, with comfort. Even the crossing straps hugging the top parts of her breasts are reminiscent of the symbols Natsume would draw in her simpler magical circles. It’s absolutely made for her.

Wataru feels it below, starting to stir. She’s not wet yet, but she’s becoming warmer by the second, admiring her topless junior in front of her, that she doesn’t doubt it will be that way soon.

“N-Nee-san?” Natsume blushes.

Someone sneezes and coughs a few doors away.

“You look so…” Cute, adorable. “Sexy.”

Wataru grows closer to her, caressing Natsume’s shoulders and arms delicately.

Natsume looks away. “You’re… just saying That.”

“It’s the truth,” Wataru murmurs. She grabs Natsume’s hand, guiding it to the spot between her own skirt. “See how I’ve become? Just looking at you…”

“Nee-san…” Natsume exhales. “From Me?”

“Who else? I am no narcissist.” Wataru slips her hands between the gaps of Natsume’s arms and torso, running up her sides, her chest, resting underneath the smooth slopes of her breasts.

Natsume bristles at the image of Wataru’s hands dwarfing her chest. “They’re-”

“They’re a perfect fit.” Wataru grazes over the middle of the cups. “Don’t you think?”

“The bra, or… Mm-”

“The fabric is on the thin side, fufufu. Will your nipples show on colder days, I wonder~”

“They Don’t-” Natsume bites another moan. “Usually perk up so Much- Unlike when you tease Them!”

Wataru relents only after another couple kneads, grinning. She then slips behind Natsume, adjusting her by the shoulders so she can get a proper look in the mirror. “How do you feel?”

Natsume purses her lips at the reflection. “From that stunt you Pulled…”

“Oya?” Wataru leans closer to her ear, hugging her waist. “You mean just from that? Or are you suggesting, when we were walking around earlier, you were feeling naughty~?”

“Nngh- There- There were so many designs we passed By. So Many… that I thought would suit You. That’s All.”

“So you imagined them.” Wataru’s hand trails down Natsume’s thigh, rubbing against the pleats of her skirt. “You imagined them all on me in a sexy montage, like a flipping through my very own gravure catalogue. That’s all?”

“Nn-”

“Or did you think of me breathless, begging for you to take them off of me?”

“I… hah… ”

There’s a hint of dampness when Wataru presses her fingers against her panties through her skirt.

“Natsume-chan.” Wataru kisses her cheek, exhaling against her neck. “Why don’t we lean into delinquency?”

Wataru presses Natsume against the wall the moment she nods, pressing her lips against hers. Her junior’s nipples prod against bra, against fabric, against another layer of bra, perking up with each rock of hips against thigh. Peck, peck, peck…

Natsume gasps, growing still when they hear a worker walking past rooms.

“Wataru-neesan…” Her eyes grow wide when she watches Wataru drop to her knees, lift her skirt, and bury her face between her thighs. “Mm-” She slaps her mouth closed, thrusting her hips toward tongue.

Wataru laps at Natsume’s panties before shifting them aside with a finger, letting her skirt drape over her face for a moment, before fixing it back up.

A whistling tune grows louder.

The angle is a little harsh for her neck, but Wataru continues her sucking, her little flicks of tongue directly against Natsume’s clit, challenging her to maintain that low volume as each footstep echoes beyond the door.

“Mm, mm!!”

Wataru thrusts her tongue between the pink folds, trailing back up to kiss and press her tongue against her throbbing bundle of nerves—sucking in between each transition, committing to going without air for longer and longer as Natsume’s breaths grow more hurried, more shallow.

Step, step, step…

Natsume’s hips angle herself more against Wataru’s mouth—grinding against nose, tongue, and lips—all until-

Knock, knock!

Natsume’s eyes roll back, trembling against Wataru as she swallows up all of her fluids.

“Is everything alright?”

Natsume resumes breathing, rapidly exhaling through her nose as she rides out the rest of her orgasm.

“I’m fine, thank you!” A voice from over replies.

“ Hah, hah, hah… ” Wataru separates, smiling deliriously at her junior as the footsteps move back to their origin.

Natsume’s legs twitch as she adjusts her panties to properly cover herself again, panting just as hard.

They conclude their decision to purchase the lingerie without another word, as they both attempt to style their clothes and hair to look presentable enough to leave the dressing room. And when they get to the register, their heartbeats still haven’t calmed entirely.

“I’m sure your boyfriend will be very happy.” The clerk smiles, checking the item out.

“I’m sure he will.” Wataru laughs. “Won’t he, Natsume-chan?”

She blushes, muttering, “…Stupid.”

———

 

It is a shame their schedules don’t allow her to observe Natsume as much as Wataru wants. But from the cameos she makes, Wataru notices the subtle change in demeanor; Natsume stands a little taller, more confidently—bold like the bit of redness that peeks through her shirt on days she’s wearing it. Her charms are more delightfully devilish, and the way Natsume glances at her chest now… It’s not out of envy, but rather something more heated.

While that earlier shpiel of characters and layers wasn’t a complete lie, Wataru is happy that her primary goal, of giving her cute Natsume reassurance in her body type, seems to have succeeded. Though, that’s not to say that her armchair psychological observations of garments having some merit isn’t a bonus.

Still, when they bump into each other next, Wataru has a sly grin, wanting to reward her junior for her development. “Say, Natsume-chan~ Would you like to help pick out my lingerie this time?”
