The Story of How Producing My Timid Older Sister Developed My Sexual Preferences

Chapter 002: The Nature of a Leg Fetishist ☆

The time displayed on my smartphone was just past 9 AM. Even though it was Saturday, I woke up early. I didn’t want to get out of bed, but I needed to piss, so I had no choice.

Letting out a big yawn, I went downstairs. I could hear the TV from the living room. It was either Mom sleeping with the TV on or my sister who was already awake.

After finishing in the toilet, I brushed my teeth. I was thinking of going back to my room when the savory aroma of coffee drifted over. When I first woke up, I felt a bit like I didn’t want to see my sister, but the smell lured me in and I ended up opening the dining room door.

“Good morning.”

“…Morning.”

My sister, standing in the kitchen, replied without even turning around. Coffee was dripping into the server. Next to it were already two Spirit Busters mugs prepared. I won those as prizes from a UFO catcher back in elementary school. They were so easy to get that I ended up winning one for every family member.

I checked the living room, but Mom wasn’t there.

“Huh? Where’s Mom?”

“…She’s sleeping in her room.”

“I see.”

“…Coffee will be ready soon.”

“Thanks.”

I had assumed one was for Mom, but apparently not.

I sat on the sofa, blankly watching TV, when my sister brought over the mugs filled with coffee and milk.

Why does she do so much for a brother like me? I really don’t understand the reason. This unconditional love with nothing in return. I know it’s familial love, but are other siblings like this too?

Thinking that, the words I had thrown at her during dinner yesterday tightened around my chest again.

“Thanks… and, um, sorry about yesterday.”

“〜〜〜〜〜〜!?”

She let out a mosquito-like noise, her previously pale face turning bright red as she started shaking her head. She’s misunderstanding something.

“Ah… no! Well, it’s not not that, but… I wanted to apologize for what I said during the meal…”

My sister sat in a triangle position on the sofa and froze with her head down. The ears visible through her thin, light-colored hair were still bright red. Yeah, when I said “sorry” yesterday… she probably thought it was about seeing her naked.

“……Mm.”

“What?”

“I’m the one… who should be sorry.”

“Why are you apologizing? I really don’t mind at all.”

“Because I showed you something gross…”

“No! It wasn’t gross… I mean, actually…”

How am I supposed to say this? The image of that body from yesterday is burned clearly into my mind. It was the most beautiful and erotic female body I had ever seen… way too obscene… There’s no way I can say that. Shit, I’m getting hard.

“〜〜〜〜〜”

A sniffling sound. As I hesitated, my sister finally started crying.

“Hey, seriously!? It’s not something to cry about! We’re family, so you don’t have to be that shocked! I really don’t think it was gross or anything! It was an accident! It was my fault—”

“…die.”

Her voice was even quieter than usual because of her sniffling, making it hard to catch.

“What?”

“……”

She’s probably saying she wants to die. I gently stroked her messy bird’s-nest-like hair and spoke as kindly as I could.

“From now on, I’ll be more careful, okay? And I really don’t think it was gross. I’m sorry, Sis.”

After stroking her head for a while, she gave a small nod.

“I’ve got some plans today, so I’m heading out. I’ll message you about dinner later.”

I said that, finished my coffee, and left the living room. In truth, I had no plans. I just felt awkward being together with her, and my instincts were sounding danger alarms that it would be risky to stay with her any longer.

・Sorry for leaving karaoke early yesterday! You free today?

I sent a message to Shiori, who had also been at karaoke yesterday. As expected, she replied almost immediately.

・Just woke up~! Super free!

・Want to get food?

・Okay! But it’ll take me time to get ready! Wanna come to my place first?

・Can I? Then I’ll head over.

・Waiting!!

I quickly got ready and headed to Shiori’s house. I met Shiori by chance in middle school and we’ve been close since. We didn’t hang out that much back then, but we’ve been spending a lot of time together lately. She goes to a different high school, but while hanging out with me she started often joining my classmates too.

She’s been in the track and field club since middle school and seems to be doing pretty well even while playing with us. Her makeup is a bit gyaru-like, but her hair is a wolf-cut short style that instantly screams “athlete.” I like how her appearance perfectly reflects her personality — she wants to be fashionable but is also serious about club activities.

When I arrived in front of her house, I didn’t ring the doorbell (to avoid parental detection) and just sent a message instead. That’s important.

The front door opened right away. Even though we saw each other yesterday, she greeted me with a huge smile. Her fangs are cute.

“Come iiin! Come in!”

“Excuse me~”

“Go ahead, go ahead!”

I put on the prepared slippers and followed behind her.

She was wearing a light blue T-shirt and sporty gray short pants with white piping. Unlike a certain someone, she was dressed in cool, summery clothes. The T-shirt wasn’t oversized — it clung to her body, showing how slender she was. Small head, delicate shoulders, and a long, slim torso typical of Japanese girls. Her whole body gives off a cat-like impression, not just her face.

“Say ‘nya~’.”

“Nya~~n.”

She looked back over her shoulder, made a fist with her left hand, and did a cat pose. Despite the sudden request, she responded instantly without hesitation. As expected from an athlete — great reflexes.

We headed up the stairs to her room. I followed a little behind.

Right in front of me were her beautifully tanned, magnificent legs. From her slender waist sprouted thighs so thick and tight they looked disproportionate. Beneath the brown skin there was soft-looking fat, but I could tell firm muscle lay underneath. Her calves had even less subcutaneous fat, and every step up the stairs made the muscles visibly swell and contract.

If her legs were short, they wouldn’t be attractive at all. But… her legs are long, and her bones are fine, just like the rest of her upper body. That perfect mix creates golden-ratio legs that are thick and healthy yet still look sleek and slender. At this point, even her thin ankles and the white Achilles tendon peeking out from her anklet socks—

“Pervert♡”

Shiori teased me playfully while I was completely lost in a trance.

Climbing stairs with tanned beautiful legs right in front of an extreme leg fetishist like me — of course this was going to happen.

“You’re the one deliberately showing them off.”

She laughed happily, looking genuinely delighted.

I leaned back against a pink floor cushion, searching for lunch spots. Shiori sat on my lap, busily doing some pre-makeup prep while looking at a round mirror on the low table.

“So anyway, Yuji put his hand on my thigh and was like ‘let’s go to another room’!”

“And what did you say?”

“‘Huh? Gross,’ obviously! His eyes were bloodshot and it was actually creepy! His hands were super sweaty too!”

“That’s kinda harsh, poor guy. I sweat a lot on my hands too, you know?”

I gently placed my hand on her tanned thigh that extended from her short pants. Honestly, I had already wanted her badly since the stairs.

“Come on… It’s fine when it’s you, Teru. Actually, I want you to touch me more.”

“Here too?”

I lifted her off my lap, turned her sideways, and held her shoulders. I slowly slid the hand that was on her thigh toward the inside and slipped it under the edge of her short pants.

“Yeah… I like it when you touch me there too.”

One cute thing about Shiori is that her face instantly shows when her switch flips. Looking up at me from around my neck, her eyes turned misty and hazy, her lips formed a slight pout, and she let out a sweet voice. She probably wasn’t acting cute on purpose — her unconscious desire to kiss was showing on her mouth.

Her adorableness made my heart race. I pressed my lips against hers hungrily. Gradually the kiss became gentler and longer. Making deliberate wet sounds, I nibbled on her small, thin upper and lower lips.

“Fu… haa…”

The moment she slightly opened her mouth to breathe, I slid my tongue into that tiny gap and ravaged the inside of her mouth without giving her any rest.

“Mmm~~~!!!!”

I slightly opened my eyes to check her face. She had widened her eyes in surprise, but as my tongue caressed her palate and gums, she started letting out small nasal breaths and her eyes melted completely.

“Nn… fuha… nn… nn…”

The lewd chupa chupa sounds gradually faded, replaced only by the wet kucha kucha of mixed saliva and air. Her neck had gone completely limp, entrusting everything to my upper arm.

Our tongues kept intertwining as if confirming each other’s love, exchanging saliva. It flowed endlessly from tongue to tongue. Shiori periodically swallowed the mixed saliva with a gulp so it wouldn’t spill. Occasionally her lower body would twitch violently like a spasm.

How many minutes had the kiss lasted? Her tongue, throat, and lower body — all these muscles seemed to be moving involuntarily now, just like her heartbeat, no longer under her conscious control.

Then, instead of a small twitch, a much larger convulsion shook her lower body. The body I was holding suddenly grew heavy. All strength seemed to have left her entirely.

I pulled my lips away. Even though it was over, her small mouth still had her short tongue twitching and peeking out.
