First Kiss
After showering, I had dinner.
Fortunately, this time Se-hee didn’t throw a tantrum and ate quietly.
Thanks to that, I safely finished dinner and went to my room.
Lying on the bed, I scrolled through YouTube videos on my phone, then opened the group chat with my friends.
They were all fired up talking about boys.
Like, where did you go with a guy on the weekend, what gifts did you get?
‘Boyfriend.’
As expected, it’s a being that will never exist for me.
Then, what about a girlfriend?
Can I date a girl?
‘That too…’
Because I’m a girl now, I haven’t been attracted to any girls either.
Last month, when we went to a jjimjilbang with friends and they rubbed my back, I didn’t feel even a trace of impure thoughts.
But it wasn’t like I was completely asexual either.
I had climaxed twice recently.
It was weird because the other person was my sister Se-hee, but anyway, I definitely felt the pleasure.
Maybe if someone else touched me, I wouldn’t react?
I imagined it.
The imagination of a stranger or someone I like touching my body.
‘Uh…!’
Chills ran down my spine.
‘It’s probably not that…’
At that moment, the door opened and Se-hee came in.
Wearing a thin pajama.
Her figure was amazing.
She’s my younger sister, but she gives off an adult vibe much stronger.
No, that’s not important.
I looked at Se-hee with tension.
“Why, why are you here?”
“To sleep with you.”
“G, go, together…? Isn’t that weird…?”
“What? Sleeping with sisters is normal. When we were little, we always hugged and slept together.”
That’s true.
Thinking about it, sleeping with siblings isn’t particularly strange.
“I get it. Let’s sleep together.”
I moved to the wall to give her space, and Se-hee lay next to me.
Facing each other.
Se-hee suddenly asked.
“Sis, did you hate what I did recently?”
“…No.”
Honestly, I didn’t hate it.
“…I didn’t hate it.”
“Then, it was good?”
“……”
Instead of answering, I nodded slightly.
At the same time, I felt extremely embarrassed.
“H, but I think it was wrong. I’m your older sister, we’re siblings, and this…”
“Want to kiss?”
My heart dropped with a thud.
Kiss?
Want to kiss?
While hesitating on the answer, Se-hee brought her face closer.
“……”
The distance narrowed, and our lips met.
My head rang.
The first kiss of my entire previous life.
I never thought I would kiss my sister.
Se-hee’s tongue pried open my lips and entered.
Warm and soft sensation.
Tongue intertwined, saliva mixed.
Se-hee pulled back from my lips and started undressing me.
I didn’t resist.
Not only did I not resist, I moved my body to make it easy for her to take off my clothes.
Eventually, I was naked.
Se-hee put her tongue back into my mouth.
This time more roughly.
She rummaged through every corner of my mouth and explicitly pushed in saliva.
She swallowed the saliva that accumulated in her mouth.
A sticky warmth traveled down my throat.
Sweet.
At that moment, my rationality melted.
“…You, put it in♥”
I blurted it out without realizing.
I made a lewd request even knowing the other person was my sister Se-hee.
I felt like I would go crazy if I didn’t satisfy my desires somehow.
“If you’re going to ask for a favor, do it properly. With honorifics.”
Se-hee gently stroked my inner thigh.
She deliberately avoided that spot.
As if teasing me.
I said in a desperate voice.
“Put it in…♥”
The moment I said it, my lower part got wet.
I should have felt shame, but I got wet.
I don’t deserve to be called older sister.
I’m just a horny female dog in heat.
Se-hee pinched and twisted my nipple hard.
“Be precise.”
“Huek…!”
“What do you want me to put where?”
My body trembled from the pain.
I barely opened my mouth.
“P, in my pussy… put your fingers…♥”
“Spread your legs. Knees together.”
As instructed, I spread my legs with knees together.
Like a frog.
It was a pose where that place was exposed defenselessly.
“Spread your pussy with your hand. Wide open.”
I brought my hand and spread that place wide open.
The inner flesh was exposed, and love juices flowed.
Se-hee looked at me with satisfaction.
“When asking to put it in, you have to do it in this pose. Got it?”
Before I could answer, Se-hee thrust her fingers in.
“……!”
I almost let out a scream.
I quickly covered my mouth with my hand.
My body tensed, and I bit down on Se-hee’s fingers inside.
“Oh my, look at how tight you are. You like it that much?”
Se-hee smiled wickedly and slowly moved her fingers back and forth.
“S, Se-hee, I’m going to…!”
“Already? I just put it in!”
My body was already boiling.
Even with the slow back and forth, the pleasure hit me intensely.
“If you want to make a sound, do it. It might be fun to have mom and dad wake up and see us.”
“W, what…?”
Se-hee sped up.
Because she slightly curled her fingers, the sensitive inner point was stimulated insanely.
Slap, slap.
With lewd sounds, love juices sprayed like a waterfall.
I bit my knuckles to hold in my moans.
“I’ll send it properly♥”
Se-hee brought her mouth and sucked my clitoris hard.
“…Hak!”
My head went white, and my waist jumped up.
Se-hee didn’t stop.
She flicked her tongue on the clitoris and pushed her fingers deeper.
“Kuek…!!”
I didn’t think I could endure the stimulation anymore.
I desperately grabbed Se-hee’s shoulders.
At that moment.
“……!”
My head snapped back, and my body convulsed.
My eyes rolled back, and my toes curled tightly.
I climaxed.
Se-hee noticed my state and slowed down her movements.
She gently wiggled her fingers and licked softly around the clitoris.
The afterglow of the climax lasted long.
A while later.
“H, haa…!”
I exhaled the breath I was holding, and my body went limp.
Se-hee pulled her mouth away and slowly withdrew her fingers.
Love juices dripped.
Se-hee held up her soaked fingers as if to show off.
“Our sister was amazing again. The blanket is all wet.”
“……”
My body cooled, and rationality returned.
‘What did I do…’
I begged my sister to spread my legs and put fingers in.
And I went lewd.
With lots of love juices flowing.
Shame hit all at once.
“Um, Se-hee…”
I closed my legs and sat up, propping my upper body.
“Will you keep this secret…? A secret only we know…”
Se-hee smiled brightly.
“You’re asking now?”
“……”
I immediately realized Se-hee’s intention.
I quickly got down to the floor.
Kneeling, I pressed my forehead to the ground.
Naked dogeza.
“Please. Keep it a secret…”
“I’ll think about it. First, stand up.”
“Uhng…”
When I stood up, my legs wobbled.
Se-hee patted the spot next to her.
“Come, lie down. Now we should sleep.”
Obediently, I lay next to Se-hee.
The blanket was damp, but since I was the one who spilled it, I couldn’t complain.
“Um, what about clothes…?”
My clothes were already thrown in the corner.
“Should I put on clothes?”
“No. Sleep naked.”
“……”
Firm.
Instead, Se-hee covered my body with the blanket.
And kissed my forehead, whispering.
“Sleep well, sis.”
“…Sleep well.”
I had no choice but to sleep naked.
Thanks to the intense climax, I quickly felt drowsy and fell asleep.
* * *
Bipibip! Bipibip!
I woke up to the alarm as usual.
Se-hee was not next to me.
She must have already gotten up.
Of course, Se-hee always wakes up earlier than me.
When I sat up groggily, cool air touched my bare skin.
“……”
Completely naked, not a single thread.
Thinking about it, Se-hee told me to sleep naked yesterday.
Suddenly, a voice was heard.
“Aigoo, a grown woman like you!”
I flinched and looked back, and mom was standing in front of the door.
“Why are you sleeping completely naked? What if you catch a cold!”
“Ah, that’s…”
My face heated up.
“B, because it’s hot…! Suddenly too hot…”
“Quickly put on clothes and come out, eat breakfast.”
“Yes…”
When I put on clothes and came out, breakfast was ready.
Se-hee, who was sitting at the table, smiled brightly.
“Did you sleep well, sis?”
“Ah, yeah…”
I sat at the table, avoiding eye contact awkwardly.
Mom asked me.
“Se-ah, today is your day off, right? Mom and I will go to the mart later.”
“That’s, I have a promise today. I was going to meet friends from high school.”
“Oh? What time?”
“I don’t know exactly when. I might come back after dinner…”
“Hmm, it might be hard to carry the groceries alone.”
“Sorry…”
I had no choice because I coordinated the date with friends.
At that time, Se-hee said.
“I’ll go with you.”
“Oh my, is it okay? Aren’t you stealing time for homework?”
“It’s okay. If mom carries it alone, it’s heavy.”
Dad smiled happily.
“Heh heh, Se-hee is so nice. She’s all grown up.”
“Aigoo, how thoughtful. You must be tired from studying. Then, I’ll buy lots of snacks you like.”
“Okay.”
‘……’
Somehow I feel left out.
Like a brat who doesn’t help with household chores and just runs around outside.
No, I usually help a lot!
I buy tofu and bean sprouts when I come back from part-time!
It was unfair, but I thought it would be better to keep my mouth shut for the atmosphere.
