Kyaa, Kyaaaaaaaang!!
My little sister's hand, the one currently gripping my wrist with surprising strength, was small. Maybe it was because my eyes were closed, but the slender fingers wrapped around my wrist... and the warmth radiating from them made my body flinch in surprise.
"...Don't open your eyes."
"Y-yeah..."
My 'little sister' spoke in a commanding tone. It was forceful. Normally I would've just ignored it, but the atmosphere right now felt like I absolutely shouldn't. So I stayed obedient.
With her still holding my wrist.
During that slow movement, I simply held my breath... and remained perfectly still.
"Eep!"
"Ahh! S-stay still!"
"Ah, uh, th-that's..."
"I said stay still, didn't I!?"
"Ah, yeah... staying still..."
Something touched the tip of my fingers. Since my eyes were closed, I could only tremble at the mysterious sensation.
Swish— swish—
And then the back of my hand began stroking something. The texture was definitely not soft. Yet beyond that, I could feel some kind of soft presence.
"...I-is this... enough?"
"......Enough for what?"
"C-can you feel it or not..."
It was slightly rough, with a somewhat slippery quality to the material. And considering where my hand was positioned and the flesh I could feel through the fabric, I realized this must be her pants.
"...No... I-I'm not really sure..."
"Haa, huu... Try to feel it properly... Ah, you still can't tell...?"
It wasn't difficult. There was no way I wouldn't know. But I answered that I wasn't sure. If someone asked me why, I couldn't come up with a clear answer. It just felt like that's what I should say. That way, I might get to feel a little more.
Swish— swish— swish—
Her arm guided my hand a little higher. The back of my hand traveled along her soft thigh.
"H-how about now...?"
"Ah... Still, I still can't really tell."
I had no idea why I was doing this right now. But there was no reason not to... so I quietly went along with whatever my 'little sister' was doing.
"Ah, can't you feel it...? This...?"
"...Ah!"
"Hup!"
The tip of my fingers brushed against what felt like a slightly protruding lower belly. My startled 'little sister' sucked in a sharp breath.
"N-not there!"
"No... I was just... staying still like you said..."
"Haaah!"
My wrist was suddenly yanked hard. Since I'd been keeping my body relaxed, my upper body lurched forward slightly.
"Hu, huuu... N-n-now...?"
"Ah..."
This time, the back of my hand definitely felt something blunt and firm.
"C-can you feel it nooow...?"
The 'little sister' who had been leaning over me... and the place that had been rubbing against my ass. It was definitely that. The moment I realized it, my heart began pounding like it would explode.
"Ah, that... uh, um... ah..."
My mouth opened and closed uselessly. I couldn't figure out what to say. So I carefully picked out words in my head. But I still didn't know what I should say.
"Wh-what exactly... are you asking me to describe...?"
Surely she wasn't asking me to give my impressions of her pussy mound. If so, there had to be some other ulterior motive... some intention I couldn't understand.
"......Y-you... keep saying it's prickly... prickly... but it's nooot..."
"Ah..."
My 'little sister' bit down hard on her lip and spat the words out like she was chewing them. Then, still gripping my wrist, she moved my hand again.
Slide— slide— slide—
They were thin shorts. And beyond those shorts, I could feel the blunt outline of her pussy mound. The back of my hand also sensed the meltingly soft flesh... and the line of her underwear nestled between them... all of it vividly transmitted through touch.
"D-do you get it nooow...? I-I don't have th-that much hair dooown there... so please, stop making it sound prickly in your descriptions..."
The sound of her pants rubbing against the back of my hand filled the air. And somehow, through my hand, I thought I could feel soft, fluffy pussy hair. But this still wasn't enough. Just touching over clothes wasn't enough to tell if it was truly prickly or if some other description was needed.
"...But even when I touch it like this... I-I still can't really tell..."
As I spoke, I unconsciously put some strength into my hand. I gently pushed the back of my hand forward, pressing firmly into my 'little sister's' pussy mound and leaving a distinct imprint.
"Kyaa, kyaaaaaaaang!!"
Immediately after, my 'little sister's' erotic scream burst out. I was so startled that my eyes, which I'd been squeezing shut, flew wide open.
"Ah, s-sorry... I really didn't do that on purpose. It just kind of—"
"Close your eyes!!"
"Ah, yeah. Closed them again. For real."
Startled by her loud shrieking, I shut my eyes once more. My 'little sister' had already taken a step back. I waved my hands in embarrassment.
"Haa, huu... huuu... Don't you dare get any perverted thoughts. Th-this is just research... You don't know shit about it, so that's why... got it...?"
My 'little sister' poured out her words like an excuse. She stomped on the floor in frustration, then the door slammed open and shut with a bang.
"Haaaa..."
Only then did I let out the breath I'd been holding. My heart was pounding so hard it wouldn't have been strange if it burst. My face felt like it might burn up from all the heat flooding my body.
"Whoa... fuck..."
I stared at the back of my hand. It looked like it had been dyed bright red, as if burned by fire.
"...Am I going crazy...?"
The heat that had overtaken my body showed no signs of subsiding. My previously calm lower half had grown uncomfortably stiff at some point.
"Wow, shit..."
Was this what it felt like to be on drugs? The world seemed to sway, I felt like I was walking on air, and my mind grew hazy. Flashes of inspiration began racing through my head.
"...So this is why artists do drugs."
Extreme arousal elevated everything. Like I was intoxicated by something... with a few screws loose, I started hammering away at the keyboard. And my cock kept getting bigger and bigger, growing painfully hard and making my pants unbearably tight. In the end, I had to lock the door and jerk off.
"...Crazy bitch, crazy bitch, crazy bitch..."
I was upset that he'd called my pussy hair prickly. It was so upsetting that I felt like I had to prove it... That's probably what I was thinking. Since I was wearing clothes anyway, and he'd only touched me over them, and I'd made him close his eyes, nothing had really happened between us. And just like I'd told him, it was purely for research, so I told myself I'd approached it with a reverent heart.
But then oppa's hand had pressed right into that spot. Shocked, I'd let out a weird noise. And our eyes had met while we were both startled. I couldn't stay there any longer, so I ran away immediately. The moment the door slammed shut, I regretted it. But I had to act like everything was fine. My reaction probably looked even weirder. No, he was definitely going to think it was strange.
"Ah, seriously... I must be losing it..."
I returned to my room and sat down, clutching my head. But something felt off... a dampness between my legs, like I'd wet myself.
"...Aaaaaaaah!!"
I held my breath and let out a scream. Instead of relieving the frustration, it only seemed to make my panties even wetter. So I quickly pulled my pants down. They were already soaked through too. I immediately grabbed my panties and yanked them down, only for a long, transparent string of fluid to stretch out.
"...Ah, fuck, seriously..."
Slap— slap— slap— I smacked my forehead hard with my palm. My skull rang and my vision spun. Then I scratched at my scalp furiously. My hair flew around and tickled my face, but I couldn't care less.
"Huuuugh!!"
I clutched my head again and collapsed onto the floor. Strange sounds kept escaping my throat.
"Ah, what do I do... fuck, shit, seriously..."
I should've stayed a little calmer. I couldn't hold it in and ended up acting like a lunatic before running out.
"...No. It's not weird."
My brain must've completely short-circuited because now I was thinking something else.
"...We're already writing incest erotica together. So what? What's the big deal? It's just research anyway. That can happen. We can teach each other the things we don't know and learn together, right? Isn't that fine?"
I muttered to myself like a crazy woman. The more I repeated it, the more plausible it sounded. It might be self-justification, but it was too convincing to just dismiss as mere rationalization.
"Huu..."
First things first, I needed to clean up. I kicked off the pants and panties tangled around my ankles. Then I grabbed some wet wipes from the dressing table and roughly cleaned myself down there.
"Ha, haaa..."
Way too much had come out. Wiping wasn't going to cut it.
"Huu..."
I also needed to cool down my burning body. My hands kept moving lewdly against my will, and I realized that if I kept this up, it would never end.
"Haa... What is this..."
I thought about changing my cum-soaked panties, but they'd just get wet again right away. So I picked up the ones I'd thrown aside and pulled them back up between my legs.
"Huu..."
By now they had cooled down, and the cold fabric wrapped around my pussy, making me shiver.
Creak—
I carefully opened the door and peeked outside to see if oppa was there. I began tiptoeing forward. After confirming no one was around, I dashed straight for the bathroom.
"Ha, haa, hu, haak!"
Bang—! Click— I shut the door and immediately locked it. Then I stripped off everything I was wearing.
"Huu..."
Shaaaaa— Cool water poured over my body. I hoped this cold water would quench the heat inside me.
"Hng... Ht, haaht..."
I had to wash my slippery lower half. I couldn't just leave it like this, so I kept rubbing down there, wiping away all the love juices. But every time I wiped, more would gush out. No matter how much I washed, it kept getting wet again. So I rinsed my body much longer than usual. Lately, my showers kept getting longer and longer.
