Luciel's High-End Boutique. Fifth Best-Seller: The Sexy Bra
The second set she'd shown me — the one that suited her best — the ribbon underboob. That one. Of the three sets I'd brought, it was the least revealing.
Hands clasped behind her back, Frill looked up at me with an expression brimming over with mischief.

"What do you think, Master? Be honest with me. How does it look through a man's eyes!"
"My lady! You can't just come down here in your underwear! You need to go back up and change—"
"I know, but I want to be judged through a man's eyes too. You're the only man here qualified to evaluate how I look, Master."
"But my lady..."
"If you feel that strongly, shall I go outside like this and ask the knights to evaluate me instead?"
"N-no, please don't!"
Lady Frill was a genuine headache. Where was the little miss who used to shyly hand over the Candy and Caramel sets when she came with her two older sisters?! Back then she'd been nothing but cute and pure. Who had gone and exposed this young lady to porn?
Anyway — you're the one who begged me to look, aren't you?! No taking it back later, got it?!
Carefully, I turned my head and gave the young lady's body a slow, thorough look. Customer and shopkeeper had built up a fair rapport by now, but this was my first time seeing Frill in her underwear. Beneath that cute, over-ornamented, frumpy dress lived a very small, white, fragile body.
She was slender. That was my first thought the moment I saw her. A slim, adorable figure — whether by deliberate dieting or by nature, not an ounce of excess flesh anywhere, just a long, straight, white line of a body. Not a single scar marked her, and staring at the young lady's exposed belly was like looking at a blank sheet of white paper. It even gave me the illusion of glimpsing a hidden cut of the main heroine from an adult anime.
"Your body is simply lovely, my lady. So slender, too. The bra and panties fit you perfectly — neither too loose nor too tight. Nothing pinching anywhere, I trust?"
I praised her body while trying to slyly dodge the actual review she wanted. But as ever, the young lady wouldn't rest until she heard the answer she was after.
"No, no — forget my body and the fit. Tell me whether the lingerie and I suit each other~ Men really are hopeless, aren't they? None of you care about the lingerie itself — you're all just so eager to tear it off and get at the skin underneath."
"N-no, of course not. That wasn't what I—"
"What about my chest? Mine's too small, isn't it? T_T"
Frill pushed her chest out toward me like she was stretching after a long sit. In the same instant, from the exposed underside of her small breast, an adorable light-brown nipple peeked briefly past the edge of the bra before slipping back in — and I made a point of not having seen.
"Honestly? It's cute. The ribbons on the bra scatter the eye, so your chest doesn't read as small at all, my lady."
"Really?! Then look at the panties too!"
"Hmm..."
This was extremely awkward. The truth was, the reason I'd kept dodging her gaze had nothing to do with the bra. It was the panties. The ribbon panties Frill wore weren't sheer enough to show what lay beneath, nor an open design that left everything on display — but cut as a matching set for the underboob bra, they were far shorter than your average pair. Which meant the top of the young lady's soft, downy pubic hair was just barely visible above the waistband. For all that the rest of her body lagged in maturing, the hair between her legs had somehow grown in without the slightest shortage, and my eyes kept drifting back to it no matter how I resisted.
"Heehee♡"
Realizing I was flustered by her exposed fuzz, she gave a childish snort of laughter — then spun around and thrust her bottom straight into my line of sight. And this time it was the ribbon popping out above the cleft of her rear that seized my gaze. A small, cute, girlish little bottom. Only now could I finally turn my head away.
Frill's rear was genuinely pretty. But her chest and her bottom alike were utterly without muscle — closer to a faintly sickly frame than a sexy one. Which was only fair. This was the precious daughter of a count whose servants would talk her out of so much as walking her own garden, insisting the sunlight was too harsh. Well — if loli's your type, I suppose! Had she been born in my world, Frill would without question have become a social media star drowning in likes and subscribers. Or an honest-to-god idol.
"It's adorable. Your bottom especially — absolutely adorable. It's the exact ideal image of you, my lady, that I pictured while sourcing this set."
"Really? Yay! What a relief!"
The young lady hid none of her delight. She was milking this stolen hour of rebellion away from her stifling life for all it was worth. For a while she paraded before me like it was a ceremony — twirling again and again in that outfit, stretching her arms overhead to bare her underarms (ahh... somebody please do something about those nipples!), hoisting up what little flesh her bottom had, then kneading and lifting and dropping what little breast she had — before turning to me with a smile.
"Still, I'm so jealous of Erina's chest and bottom... What if I'd been born a woman built like that?"
"Well now. As I keep saying, every woman has her own charm. You, my lady, possess cuteness of the very highest order. That wins the hearts of plenty of men."
"But men like big chests and butts more than cute, don't they?"
"For a woman, a large chest and rear do nothing but slow her movements. She carries constant shoulder and back pain, draws only men obsessed with her body, and life grows harder for it. And the common wisdom holds that busty women are mostly airheads, besides."
There — happy now? This was getting tiresome. Enough with the envy already. Meanwhile, why wasn't Erina coming down? Had something gone wrong in the changing room upstairs?
"Hmhm. I wonder if you'd say that looking at Erina herself? Sis! Come down already!"
"M-me too?!"
Erina's badly flustered voice floated down from the second floor.
"If you don't come down this instant, I'm not buying that lingerie~ So sort yourself out."
"O-okay. One moment..."
After a beat of hesitation, the wooden stairs began to creak. And with every step Erina took, another sound rang out in time with them.
Ting-a-ling. Ting-a-ling.
A bell? A small, chiming bell. This was unmistakably... attached to the nipple covers?!
Ting-a-ling. Ting-a-ling.
"Aahh...!"
Erina, in the nude — no. She was decidedly not nude. Erina, wearing the third sexy set I'd recommended — nipple covers and a string thong — was walking slowly down the stairs. The chiming was indeed coming from there.
Ting-a-ling. Ting-a-ling.
"Hnngh..."
With every step the little bells swung wildly, and Erina's face burned redder with each one, drowning in shame.
Why on earth is she wearing that thing?!
Ting-a-ling. Ting-a-ling.
Struck dumb, I could only watch as that female figure — no, as Erina — descended the stairs. No — in truth I should have stopped her. What do you think you're wearing? Merchandise meant for a noble lady is not for the likes of you to put on. But I'd known the reason long before she reached the bottom. Anyone could see Frill had forced it on her.
"Hnnnn... don't look at me..."

Once she reached the ground floor, Erina couldn't bring herself to face me looking like this; she hung her head low, cold sweat beading down, her face scarlet. No — it wasn't only her face. The tone of her entire white body seemed to have flushed a pale pink.

Even so, her hands were folded neatly over her lower belly, shielding it. For all her obvious shame, the reason she covered that spot rather than her nipples or her sex seemed to be that she didn't want Lady Frill to learn what she was. The slave brand etched above Erina's womb. That inverted triangle was a seal of authenticity of sorts — proof of goods vetted by the slave market.
Fortunately, Frill didn't seem to have caught it — apparently she hadn't examined Erina's body in full, only her chest and rear. Truthfully, even if she had learned Erina was a slave, it would have changed nothing. To a noble lady, commoner and slave are equally beneath her.
Frill, giddy with excitement, chattered on with Erina's all-but-naked body on display before her — rather like me presenting a top-shelf luxury item.
"You see, I actually wanted to have Erina try on all three of the sets I was going to wear? But the first and second were such a poor fit they looked about to split at the seams. Then I couldn't wear them at all! Unthinkable."
"Why on earth would your lingerie go on my employee..."
"But the third one looked like it would fit her beautifully! I thought to myself, this one could handle even a monstrously huge chest like hers!"
She wasn't wrong. This was closer to an adult novelty than actual lingerie... It didn't come in sizes. It was all one-size-fits-all.
"Have you tried these on yourself, my lady?"
"Of course I tried every one! And I made up my mind. The last set I won't wear myself — I'll dress my maids in it! We've quite a few maids at the estate with lovely figures, if not quite Erina's level!"
"Ha ha... your maids are in for quite an ordeal, then!"
What a twisted hobby. Was she planning to skip wearing it herself and summon her young maids night after night to play dress-up with this stuff? Without meaning to, I had become an accomplice to the young lady's mischief. ...Whatever. What went on in her manor was no concern of mine. So long as the young lady was pleased.
"Then I'll wrap all three sets. As I always say, these were specially ordered for you, my lady — no new stock exists. I must warn you that exchanges or refunds will be difficult."
"You know it always sounds so strange when you say that? Exchanges, refunds. Yours is the only shop around that talks like that."
Fair enough. Where in this other world would you find exchanges and refunds? And yet, astonishingly, I did occasionally permit them — for VIPs only. Never for underwear, of course. But what noble's wish goes ungranted? It was lip service, a courtesy implying she was such an important customer she could exercise such privileges. Had a single customer ever actually requested one? Not once, ever. They all had their pride. Pettily returning something they'd bought once would stain their honor, so even if they wanted to, they wouldn't. I'll admit it freely: if you're going to do business, doing it in another world is dozens of times better.
"This one and this one. Just those two, please. And this one — I'll wear it home."
The young lady indicated the black mesh lingerie in her hand and the adult novelty Erina was wearing.
"You'll wear it home as-is? Won't it be uncomfortable in the carriage?"
"I think I'll rather enjoy it? Heheh♡ No one will ever know I have such vulgar lingerie on under my dress~"
A genuine pervert. Truly. It would be sheer torture in a jouncing carriage. The ribbon panties, all but a T-back, would keep rolling up between her cheeks, working at her most private place without pause. The bra was worse. With no full cups — the design bared the underside of the breasts — nothing would hold them in place; every time Frill raised her arms they'd ride up and put her bare chest on display. Her bared nipples would brush and drag against the dress fabric, teasing her without end. Well — if the discomfort is paid for in arousal, then by all means, wear it home. Already picturing the ride home, perhaps, the young lady's cheeks had flushed the pink of a schoolgirl who'd sneaked a drink behind her teacher's back.
"Then, Miss Erina, if you'll go back up and change—"
"Why all the fuss~ Just take it off right here~"
Pop.
Before I'd even finished speaking, Frill had slipped her fingers inside Erina's nipple cover and undone the clamp.
"Eek!"
The instant the cover guarding her breast — guarding, precisely, only the border between nipple and areola — fell away, Erina let out a small cry and clapped a hand over her own mouth. And with that, the slave brand on her lower belly came into view.
Her expression said it all: if a scream escapes outside, the scary men will come swarming in~
A nod. Erina dipped her head in silent agreement.
A sidelong glance. The young lady stole a look at the inverted triangle branded on Erina's lower belly — then, smiling slyly to herself, peeled off the panties she still wore.
"Shall I take off the other one and the bottom for you too? Sis~?"
"No, no! I'll do it myself! Hnngh!"
Erina removed the other cover. A zigzag line of teeth marks was left printed on her pinched nipple. When it came to the bottom half, shame outweighed pain; sweat poured down Erina's face like rain.
"A body like this, and not one hair grows down there — like a little girl. You're my exact opposite!"
"P-please don't tease me, my lady..."
"I'm not teasing? I'm just jealous, that's all. Jealous."
Only now taking a proper look at Erina's snow-white, fuzz-free mound, Frill practically drooled. I'd verified it many times before: Erina had no pubic hair at all. Even after three-plus days nothing had grown back, so she seemed simply hairless by nature. Perhaps because of that, ever since laying eyes on the young lady's downy fuzz, Erina seemed to have filed her own bareness away as a fresh source of shame.
"Phew..."
At last, Erina had shed every last shackle that had bound her body. Though she wore not a single thread, this state somehow seemed easier on her mind; I could see with my own eyes her pink-flushed skin gradually settling back to its natural white.
I arranged the sexy lingerie sets — still warm from Erina's skin — sealed them in plastic bags, and tucked them into a shopping bag.
"Anything else you need?"
"This should do nicely! The sanitary pads, and now three beautiful, adorable sets of lingerie — I'm so happy! I finally feel like a real woman!"
"I'll tuck in a few sweet dessert treats. Munch on them in the carriage if you get bored."
While the young lady stepped back into her dress with Erina's help, I picked out caramels and jelly packets, candies, and a few chocolates she'd enjoy — one of each kind — and slipped them into the shopping bag. The top of the bag was buried under colorful sweets, so even if a servant outside happened to sneak a peek inside, it would look as though the young lady had bought nothing but a few snacks. So arranged, I handed the bag over, and the young lady took it with a satisfied smile and slung it over her shoulder. Erina had naturally taken up her post by the door.
"Sis, I'm about to open the shop door — are you planning to follow me out and see me off? Dressed like that?"
"Aaah! I'm sorry!"
Only then did Erina register that she was still stark naked, and she scrambled to hide herself in the back of the shop.
"You've nothing to apologize to me for — though had you done it, everyone might have thanked you for the lovely show? Heehee♡"
Frill blew a playful hand kiss to Erina and me.
"Thank you for today. To you, Master — and to your new 'slave' employee."
!!
"I'm ever grateful you remember us each time. On your next visit, I'll have goods prepared that will satisfy you even more."
"I'll look forward to it, then~"
Whoosh. Ding-a-ling.
The moment I opened the shop door, a cold gust swept in. Everyone outside had been waiting for this very instant, it seemed; they snapped into escort formation as one.
"She's coming out!"
"My lady, have you finished your shopping?!"
"Allow me to take your purchases."
"...Yes?"
"Y-yes, of course. My apologies!"
One servant reached out to take the young lady's shopping bag, but she ignored him and climbed quietly into the carriage. Before the servants and knights, she had reverted — as if none of it had ever happened — to the noble daughter of a count.
"Thank you truly for today. Please visit us again."
"One moment. Come here."
?!
Just as I bowed and moved to see her off, the young lady called to me from within the carriage, some thought apparently striking her. I leaned my ear to the open carriage window. Frill wanted to whisper.
"Next time, have something even stronger ready~"
"Something stronger... like what?!"
"You'd know better than anyone, wouldn't you, Master? Heehee♡"
And with that, Frill beamed at me, radiant. The escort knights and servants watching from a distance seemed smitten by that innocent face; for a few seconds they couldn't hide their dazed expressions.
"Now, let's see."
"Ah, wait — I think I'm fine."
"Fine, nothing. You could have a scratch somewhere for all we know."
"Yes..."
Once Lady Frill had gone and I'd shut the shop, I didn't head straight back to my office; I spent a good while inspecting Erina's body for injury instead. Honestly, there was self-interest in it. But Erina had been examined by me before — after the bandit raid and the village youths' assault — so she submitted to the check-up without protest. If anything, after baring herself before me so many times, she'd grown more or less used to it. Her face made it plain: showing skin in front of me was easier than in front of Frill, a fellow woman.
First I checked the marks on her chest and waist. The sets were free-size, using wires and bands that stretched to fit the wearer, but with a chest far larger than most women's, Erina had been left with clear line-like impressions beneath her breasts, along her inner thighs, and across her back.
"My skin is fair and delicate, so marks like these show easily..."
"That much is true. I do wonder how you kept this skin intact on the slave ships bound for this country."
The slave ships out of Abella, a nation defeated in war, were cargo vessels illegally refitted to maximum size, built for one purpose: packing in as many bodies as they would hold. The space allotted each slave within was less than a single square meter. There they ate, slept, and soiled themselves in place for roughly three weeks to a month until reaching Helion, and the ships' hygiene was infamously the worst. Set out with three hundred slaves, a ship might arrive with two hundred fifty still breathing. Even so, the slave ships heaved the corpses into the sea and sailed the same route again and again. Whether fifty died or a hundred, the survivors made it far the more profitable voyage. That was why none of the surviving slaves arrived with their bodies whole.
"Well... the ship's captain treated me specially, as top-grade merchandise. He let me sleep apart, in a small room beside the captain's quarters, and gave me food enough... Of course, he never laid a hand on me. If I lost my maidenhood, my value would drop..."
"Figures... Less a kind man than a pragmatic one. Like me."
"What are you saying? You're kind, Master."
"I'm not kind. I'm a merchant with eyes only for money."
"You may think so, but you are kind. I guarantee it."
Awkward. I hadn't needed to ask a question like that.
Then I got down to business and examined both of Erina's nipples. The left was fine, but the right had been squeezed by the clamp — slightly flattened, pointing somewhere it never did before. I tore open one of the women's lotions I sold and worked it over both nipples and across her entire breasts besides.
"Aaah..."
"Hold still."
Odd — the more I worked them, the more the nipples seemed to swell. Don't tell me my hands were exciting her? Still, both swollen tips had gone glossy and smooth, pleasant to look at.
"Let me check below, too."
"...Yes."
I cleared off a small display table for Erina. She climbed onto it without ceremony and lay back, spreading her legs like a frog pinned for dissection, hands hooked behind her knees to hold herself open — positioning herself so I could observe with ease. It was an obscenely lewd posture at a glance, but Erina had held this pose for me before (out in the open on a dirt road, no less), so she showed no reluctance about baring even her sex. Above all, she believed her body belonged to her master.
"It's... sort of burning down there... I'm not hurt, am I?"
Like a patient at a gynecologist's office, Erina wore a worried frown.
Why was it... like this here? Erina's mound was flushed a red so deep it stood out against every other part of her at a glance. Aside from the panty's strap there should have been nothing pressing there, and I could roughly guess why it out-red even her nipples — but I feigned gravity all the same.
"This looks a bit swollen, too."
Erina's clitoris stood stiff and erect, its hood drawn back like a man's. Careful, I slicked my fingers with lotion and gently drew at the outer folds of her sex, her clitoris, and the wings of her lips besides, easing the lotion thoroughly into the backs of each fold.
"Hnnn...."
Throb.
Unable to hold it back, Erina's spread pussy clenched down once, hard, and a small measure of white juice welled out from within. An ivory secretion, as clean as her skin and blessed with a fine viscosity.

"Ah... I'm sorry...!"
"It's fine. If anything, it means you're healthy — that's a relief."
Rub, rub.
From there on I set the lotion aside and used the slickness Erina had made herself, massaging her whole sex gently enough to hurt nothing.
"....."
"....."
A strange current ran beneath the silence. Eyes screwed shut, lips clamped tight, Erina was fighting with everything she had not to moan. I knew why she reacted that way. This was treatment. She believed that since her master — me — hadn't asked for her body, a slave growing aroused first would be an insult to him.
By now my cock felt ready to burst through my suit trousers. Haah. God, I wanted to fuck her senseless. Did I, her master, truly need to hold back from sex with Erina?
"Master......"
I'd paused the massage, hesitating — and in that moment Erina opened her eyes and looked up at me. She knew exactly what I was thinking.
"If you want... you may come inside... I'm ready whenever you are..."
"Mm..."
At those words I felt the thread of reason in my skull begin to give way. Not snapped clean through — more frayed halfway, a few strands parting. A beauty like this, in this state, in this position, saying these things — if I didn't oblige her, the fault would be mine.
Zzzzip. I slowly drew down the zipper of my suit trousers. Then, easing my underwear down inside my pants, I carefully freed only my rigid cock, already damp with precum. If I didn't undress fully — just slipped it in and out a few times, briefly...
I caught Erina's body shivering faintly at the sight of my erect cock. Her great breasts, splayed out as she lay, rippled with the tremor — making it all too easy to confirm she was shaking.
Finally. Sex. She couldn't see it from her angle, but she'd sensed my cock come free — and sensed that soon it would be inside her.
A gentle press♥
The instant the tip of my cock barely kissed the entrance of Erina's pussy, sharing the faintest thread of warmth between us—
Knock knock knock.
"Pardon the intrusion. Have you closed for the night?"
I jolted. Goat's voice drifted through from beyond the inner door to my office.
"Yeah. Just wrapping something up."
"Very well. Then, if it's no trouble, I'll have a late-night bite ready for you both."
"...Thanks."
Goat's footsteps faded away from the inner door. I never heard him come. When had he arrived? No — we couldn't have heard him. In that moment, neither of us could have noticed a marching band.
"Hnnn...."
Erina lay with her face burning scarlet, head turned aside. In her embarrassment, one hand covered her breasts — more than a single hand could hide — while the other shielded the mound soaked with her juices and beginning to dry sticky.
"Well, then,"
I sighed and tucked myself back into my trousers.
"You've earned it. Shall we go eat that late-night snack?"
"Yes!"
Swaying, Erina rose from the table. Her head must still have been swimming; she wobbled up the stairs like someone drunk and began pulling on the clothes she'd left in the changing room. Feeling awkward simply waiting on her, I tidied the merchandise across the empty table as I spoke.
"You did well today."
"Really?!"
"Study the merchandise a little longer and you'll be minding the shop on your own in no time."
"I'm so glad! I'll work hard!"
The praise seemed to put a spring in her step; she thumped down the stairs. Then, before I could so much as hesitate, she was right in front of me —
Mwah♡
Rising on tiptoe, she pressed a light kiss to my cheek.
"See? I told you — you really are kind, Master."
Erina... you, right now...
Your top's on backwards?
