“Take just one step back, sis.”

At my words, my sister, who was standing in the living room wearing a sleep mask, asked,

“Here?”

“Yeah. That’s right in the center of the living room.”

The purpose of this experiment was to see how well my sister could find me by my scent.

The method was that I would stand somewhere in the living room, and my blindfolded sister would find me using only her sense of smell.

Seo, my sister, was my experimental assistant and subject, and the compensation for her participation would be paid in sex.

“You really will do it if I find your scent, right?”

“Of course. I promised.”

“…But why do I have to be naked?”

As she said, my sister was standing there naked with only a sleep mask on.

“Because it looks good.”

“…Pervert. It’s unfair if only I’m naked, so you take your clothes off too.”

“Wouldn’t that make it easier to find my scent?”

“You just took a shower. I’m not a dog; you need to be naked to have any chance of finding me.”

What she said made sense, so I nodded in front of her, who couldn’t even see me, and replied,

“Alright, I’ll take them off.”

After I took off all my clothes, the experiment began.

There weren’t any special criteria for ending it.

It would just end when I was satisfied enough.

“Why do I have to do something like this, seriously…”

My sister grumbled, but still slightly lowered her posture and looked around.

Soon, as if she had sensed something with her excellent sense of smell, she slowly began to move her feet.

‘…But where is she going?’

She was moving with a direction, but it was in the completely opposite direction from me.

It seemed like she was heading towards the balcony, and if I left her like that, she might trip on the threshold, so I hurriedly ran to her, calling out to her.

“Sis, wait!”

“Huh? Why? Am I not here?”

I said to my sister, who took off her sleep mask and asked me,

“This is the balcony. It’s completely opposite from where I was.”

“That’s strange. I definitely smelled your scent.”

“You smelled my scent? Ah!”

Something came to mind, so I looked outside the balcony.

There was a laundry basket right where you could see it after crossing the threshold.

“Don’t tell me you smelled the laundry and came here?”

“Ah, I guess so. I told you, I smelled your scent.”

“Seriously, that’s amazing, sis.”

I let out a hollow laugh of disbelief and admiration.

The living room was by no means small, but how could she smell the laundry on the balcony, not even in the same living room?

“Is it over now? Stop doing perverted things and let’s go to your room.”

“Just a second. Let’s try it one more time.”

“Ugh, no! Let’s just go to bed, okay?”

“I’m just really amazed. Just one more time!”

“Haa… It’s not like you’re a kid; what’s so amazing about this…”

Reluctantly, I put the sleep mask back on my sister and returned her to the center of the living room.

I also took a spot in the corner and stood there, watching my sister, who was still sighing.

“You can start whenever you’re ready.”

“…”

This time, she slightly lowered her body and looked around.

Thanks to closing the balcony door, there was no chance of being tricked by the laundry scent now.

“…Hey. You are in the living room, right? If you hide or something, you’re dead!”

“Don’t worry, I won’t. I said I’d move just once.”

I went to the opposite corner and continued to watch my sister.

It was funny to see her standing there naked with only a sleep mask on, and it was subtly arousing to watch her breasts shake whenever she moved her upper body back and forth.

“I can’t do it. I feel like I’m going to fall.”

She completely lowered her body and began to chase the scent while crawling like a cat.

“…Is it this way?”

She cautiously moved forward on all fours, sticking her nose out.

Her breasts peeked between her alternately extending arms, and her plump buttocks wiggled as her kneeling legs crossed.

My sister, however, didn’t even know how seductive she was right now and was focused on finding my scent.

“Oh!”

She who had been advancing carefully, picked up the pace with confidence.

“It’s here! …What is it?”

What my sister found was the pair of underwear I took off when the experiment started.

It was bait that I had thrown far away from me to confuse her.

“Hey, did you deliberately leave this here?”

My sister, who raised her sleep mask, looked at me and asked, and once again, I couldn’t help but admire her.

“Sis, how do you do it? If you were born as a dog, you would have been a drug detection dog?”

“Ah, whatever. Anyway, I found your scent, so let’s stop now.”

“No, let’s try it just one more time. This is the scent of my underwear, not my real scent. This is really the last one! Or I’ll cut off my dick.”

“What are you going to do if you cut that off! …Haa. Really, this is the last one. Don’t you dare say anything else.”

“Thank you. You’re the best, sis.”

Even though she said she didn’t want to, she ended up listening to me, so I always ended up pushing my luck when I was with my sister.

Anyway, thinking that this was the end, I put the sleep mask on my sister and took a spot on one side of the living room and stood there.

“…Oh? I know.”

My sister, who was crouching down like before, crawled over with the same seductive posture.

Since it was exactly in the direction I was in, it was only a matter of time before she found me if she continued like this.

“Sigh, is it here?”

She stretched her neck out and reached right in front of me.

Finally, when her nose was about to touch my dick, I unknowingly stepped back and widened the distance.

“…Huh?”

My sister, who felt something was wrong, carefully chased after me again.

I maintained a distance that was just out of reach and continued to step back, and each time, my sister slowly but tenaciously followed the lingering scent in the air.

‘I need to stop at some point, but I can’t stop.’

Seeing the sight of her crawling towards me naked with only a sleep mask on from the front made it hard to take my eyes off her.

No, why is she sticking out her tongue and trying to lick me?

She really looks like a dog like that.

While I was holding back the laughter that was about to escape, my sister, who felt something was wrong, suddenly raised her sleep mask.

I flinched and hurriedly stopped, but it was already after she had caught me stepping back.

“…Damn it. I’m not doing it.”

“Ahaha. Sorry, sis. Just kidding, just kidding!”

My sister threw the sleep mask on the floor and tried to go to her room, so I hurriedly went and grabbed her.

I shouldn’t laugh, but seeing her sulky face, I couldn’t help but burst out laughing.

“That’s it. I’m going home.”

“Ah, I’m really sorry! It’s because you’re cute. I’ll never! Never do it again!”

“…Let go. I told you I’m going home.”

“No, no. I was wrong, don’t go. You said you wanted to do it with me. I want to do it with you too, so please don’t go. I’m sorry. Huh?”

“…”

Thanks to my desperate plea, I barely managed to stop her from going home.

However, the peach pit under her lips was still there, so it seemed like she needed something to appease her.

“I’ll make you feel really good. Please cheer up.”

“…Really?”

“Yeah! Trust me!”

My sister, who had been staring at me with her pretty eyes for a while, opened her mouth.

“If it’s not good, I’m leaving right away.”

“Alright! Don’t worry and come over here and put on the sleep mask.”

“Sleep mask? Why a sleep mask…”

“Now, trust me and stand here and wait.”

“…”

Seeing her pouting with her lips sticking out, I knew that I couldn’t appease my sister with half-hearted efforts.

There was no need to worry.

Because I had a tool that was as good as Doraemon.

I turned on Sex Wiki, hidden from my sister who couldn’t see because of the sleep mask.

She’ll definitely feel more than usual with this, right?

[Alert: Saved. Used 1 Wiki Point. (Current points held: 1)]

Like this, one more lewd attribute was added to my sister’s body.

But as much as that, the ways I can enjoy myself with her increase, so wouldn’t that be a benefit to my sister too?

“…Hey. How long do I have to wait?”

“Ah, sorry. I was just looking at my phone because an alarm came. It’s done now.”

After calmly making an excuse, I narrowed the distance with my sister.

I was clearly doing this to make her feel good, but seeing her standing naked in the wide living room made me feel like I was being treated.

“I’ll start.”

“Eunghuup…”

I stole her defenseless lips and pushed my tongue in.

My sister’s shoulders flinched as if she was surprised, but soon the tongue inside came out to greet me.

“Hueung, tssup… Huup, auup♡ What, what is it. It feels different than usual…”

“Does it?”

I pretended not to know and continued the kiss.

Her scent and the saliva touching my tongue were so sweet that I felt like I was the one who was caught by Sex Wiki, not my sister.

“Huuup, uup, huup… Tssuuup, haa…♡”

The other person’s breathing was getting rougher.

Leaning her body in my arms because she couldn’t see, she rubbed her thighs together as if she was impatient.

“Tssyuuup, hua. Haa… Haa…”

Seo was breathing so hard that her chest noticeably rose and fell as soon as she took her lips off.

I couldn’t properly see her expression because of the sleep mask, but the sight of her sticking out her tongue and panting below her covered eyes was extremely seductive.

“More… Do more. Kiss…”

As soon as I heard her voice, I went back to her face.

However, the place I arrived at was not her red lips, but her pure white neck.

“Eut, haa…”

I lightly caressed her neck with my lips.

Then, when I tickled it with my tongue, her shoulders flinched once again.

After caressing the place touching my tongue like that and going down, I bit the nipple that had been slightly erected as if it had been waiting.

“Heua, eut… Nipple feels good…”

I gently massaged the other breast that had been left unattended with my hand.

My sister liked being squeezed hard more, but now was the process of warming her up so that she could feel even greater pleasure later.

“Haaa, suck it more…”

When she hugged my head, the softness and warmth of her skin were felt even more strongly.

The nipple in my mouth was already completely hardened.

When I was laying it back and forth with my tongue, tickling it playfully, I felt a warm touch between my legs.

“Eut. Dick…It’s much hotter than usual. I feel like I’m going to get burned…”

“It’s because it’s more sensitive because your eyes are covered.”

“Heheut, I guess so…”

“It would feel even better if you smelled my dick right now, right?”

“…”

Instead of answering, she nodded with a red face.

I quietly approached her ear and whispered in a low voice.

“Do you want to smell it?”

“…Yeah.”

I could feel the shyness in her answer, but there was no hesitation, and soon my sister lowered her body in front of me.
