IF Side Story: Little Sister and Chocolate
This chapter is a side story to the previous episode, Little Sister and Chocolate. It contains a considerable amount of material some readers may find filthy, and if foot fetish isn't your thing, you are more than welcome to skip it.
As a side story, skipping it will have no effect on the main plot.
It's literally just a side story, after all.
This extra features feet only.
Armpits next time...
"Oh. Pretty spacious."
Carrying the drinks we'd picked up on the first floor, I stepped into the private room with my little sister, and a space far more comfortable and open than I'd expected unfolded before us. It was my first time at a Room Cafe, so I'd been a little worried it might feel cramped — but the soundproofing was solid, and they'd even laid out plush cushions and blankets properly.
Best of all was the cool air blasting from the air conditioner running at full tilt.
"Wow! It's so cold in here~~"
A little hop. Hayeon kicked off her shoes and jumped, vanishing into the pile of cushions with a soft, muffled thump, and the sight of her was so unbearably adorable I could hardly stand it.
...Why, though? Was there some kind of charm-bonus effect that made even the most ordinary gesture extra cute just because my little sister was the one doing it?
The soles of her feet, showing through her nude stockings in a way that was almost indecent. The small, round curve of her ass peeking out from under her shorts. The sticky sheen of sweat in her armpits whenever she lifted her arms... All of it was so unbearably precious I wanted to burn it into my eyes forever.
"What are you doing, Oppa? Don't just stand there — come sit next to me."
"......"
"Oppa?"
"Huh? Yeah?"
I hadn't even registered that Hayeon was calling me. I'd been staring blankly at her feet through the stockings, and I startled. When I hurriedly looked over, Hayeon was staring right at me.
"Oppa? Is there something on my feet?"
"Ah? I, well..."
How to put it. Getting caught staring at my little sister's feet felt like it would be incredibly embarrassing. I fumbled, not knowing where to look, and Hayeon — watching me flounder — smiled in a way that suggested she'd figured something out.
"Were you staring at my feet, by any chance?"
There was a subtle shift in Hayeon's tone...
Caught staring at her feet, I panicked, terrified that my beloved little sister might have been disgusted by my gaze.
"Uh, uh...?"
Maybe that's why I couldn't answer her right away — and that hesitation was the decisive moment that turned something she might have let slide into a certainty.
"Come to think of it, you kept sneaking glances at my legs the whole way here... Oppa, have you been staring at my feet this whole time?"
"No. It's just, the way you were sitting, I couldn't help but see them..."
"Hmm, is that so? For something you 'couldn't help,' you were staring pretty hard..."
"Th-that's..."
Seeing the panic on my face, Hayeon let out a little snicker.
"Hehe. Why are you so flustered, Oppa? It's only natural for an older brother to get horny looking at his little sister's toes, isn't it?"
"Uh... is it?"
"Yep. Especially a dog-dick mutt like you, Oppa — you're a pervert who gets off just from smelling my feet, right? If anything, staring at my feet is the most natural thing in the world."
Now that she mentioned it, she was right. I was her older brother — a dog-dick mutt — so of course I'd get turned on looking at my little sister's feet. Why had I thought I should be embarrassed? If anything, acting ashamed might hurt my precious little sister's feelings.
Once that thought had settled into place, I realized just how timid and stupid I'd been.
"Sorry. I got confused for a second. I thought looking at your feet would make you uncomfortable... But of course a foot-rag like me getting horny over his little sister's feet is the most natural thing in the world. I'm sorry..."
"Aww, Oppa. You don't have to apologize for something like that. If you really feel that bad about it, why don't you start by giving my feet a little massage?"
With that, Hayeon arranged a pile of fluffy cushions and propped her legs up on top of them. Her toes showed through the stockings, faintly, indecently.
The sweltering heat of the day hadn't been so easily banished by the air conditioning. Her body was still giving off a faint sheen of sweat — and especially so in those stockings, which didn't breathe at all, still radiating a muggy warmth. After walking around all day, the stockings were soaked through with sweat and humidity, spreading a damp warmth into the air around them.
And of course.
After spending the whole day in stockings that didn't ventilate at all, the moment Hayeon set her feet on the cushions, a peculiar scent washed over me.
...Sweat? Ah... it's sweet...
Every older brother, in order to get horny for his little sister as easily as possible, is instinctively equipped with a heightened sensitivity to every scent she produces. This is something you learn as a required unit in middle school health class: an older brother's sharpened sense of smell, attuned to his little sister, will send him into heat from nothing more than the scent of her sweat or her pheromones.
That is an older brother's natural response.
Even the smell of his little sister's feet, trapped in stockings all day long, registers as nothing but fragrance...
...Hahh. So fragrant...
And besides, Hayeon was the perfect little sister. Long, jet-black hair without a single strand out of place. Pale skin and a face so adorable it defied description. She'd never once given our parents a moment of grief, never once caused any trouble — the treasure of our family.
If it was the foot-scent of a little sister that perfect, of course it would smell sweet.
And as if on cue, Hayeon's stocking-wrapped foot came right up to my nose.
"Sniff sniff... hahh..."
A thick scent rolled off Hayeon's foot, now right in front of my face, and a shiver ran down my spine before I could stop it. I pressed my nose against the sweat-soaked stockings, sniffing, drawing the air in deep, sending that dense scent through the membranes of my nose straight into my brain.
It was a hot summer. Hayeon's bare feet, trapped all day in stockings that didn't breathe, were packed with steaming heat and moisture. After being worked so hard in the sweltering weather on the walk here, they were soaked through with sweat.
"Mm. That's it..."
With that satisfied little murmur from Hayeon, her small, cute toes wriggled primly inside the stockings. And with that, the smell grew even stronger...
Smelling my little sister's feet is... the most natural thing in the world...
Recalling that piece of common sense as it replayed in my head, I slowly peeled the stockings down Hayeon's legs. The nude-colored fabric slid down her smooth skin, bunching thicker as it went. When the bunched-up stocking caught for a moment on her heel, I yanked it the rest of the way off.
".........!!"
A scent far stronger, far denser than before. The steaming heat and humidity trapped inside the stocking were released all at once, and her bare foot emerged, flooding the air with an addictive, nose-stinging fragrance.
Hayeon's bare foot, pale as snow. Even after walking around all day, that milky-white foot was full of a sweet fragrance... I slowly buried my nose in it and inhaled even harder than before.
"Well? The smell of your little sister's feet, sweaty from walking around all day... For a dog-dick mutt like you, Oppa, that's the best reward there is, isn't it?"
"Mmh..."
"Does it get you hard? You perverted little shit?"
I jammed my nose between her toes, where the scent was most concentrated, savoring that milky, velvety texture as I drank in the smell — and then, on impulse, I stuck out my tongue. Just like I did every morning, I began servicing her toes, one by one, in every crevice.
"Mm. Get between the toes more thoroughly... Hah, fuck. That's it..."
A satisfied moan from my little sister. I was sliding my tongue between her toes, sucking each one with wet little pops, when—
"What's this, Oppa? Did smelling your little sister's feet get you that worked up?"
Hayeon had noticed the bulge tenting my crotch. She grinned, then peeled the stocking off her other foot. Another pale, milky-white bare foot emerged, just like the first.
So white, so soft, it didn't feel dirty in the slightest. But it was still a sweat-soaked foot that had been trapped in a stocking all day. No matter how pretty and perfect a girl Hayeon was, she couldn't hide the thick body odor coming off her feet.
I was just about to clean that foot the same way when—
"Wait. There's something we need to do first."
A rustle. At some point Hayeon had grabbed some chocolate — the free kind they give out in the first-floor lobby. True to her sweet tooth, she'd apparently picked up one of each kind. She unwrapped one and held it in her hand.
"Oppa. Do you like sweet things?"
"Not really, I'm not much of a sweets person..."
"Then how about this?"
A squeeze. Hayeon wedged the chocolate between her toes.
"......."
Her pale toes spread, clamping the chocolate firmly in place. Chocolate melts when it meets heat. And of course, the space between Hayeon's toes — freshly freed from the stockings — was packed with steaming warmth. The chocolate began to melt almost immediately.
A slow drip...
A sticky, sweet brown liquid trickled down between her toes. At the same time, the pungent, dense body odor of my little sister's feet mixed with the sweetness of the chocolate, and a cloyingly sweet smell filled the air...
"Sniff sniff..."
"Ah. It's so sticky..."
The chocolate, warmed by the heat between her toes, kept dripping down — and there was only one choice for someone who couldn't bear to see that precious chocolate cream go to waste.
A kiss.
I pressed my lips to my little sister's foot, reverently.
And licked the sweet chocolate clean.
