8.
“Slurp… suck… suck…”
As with yesterday, pleasure surged from his lower body.
‘Ah, right… I told Ji-na to do this every day…’
I wanted to sleep in a bit more today…
“Oppa? Are you awake? Do you want to sleep more…?”
Her tone sounded a little disappointed at the end.
Ah, right.
‘We were supposed to go buy a bag today…’
I had forgotten.
“I’ll get up… Just suck it once for now…”
“Okay!”
Immediately, Ji-na’s oral service began.
A person’s mouth is soft.
Softer than expected.
And the tongue—how could it be so soft yet so pliable and able to move freely?
With that tongue, Ji-na was caressing my glans.
She licked the surface, then slowly slid across the slit.
A shiver of pleasure spread throughout my entire body.
When Ji-na pressed her lips to my glans and sucked upward, it felt almost like the pleasure of ejaculation.
At the same time, the residual urine or unreleased semen in my urethra flowed into Ji-na’s mouth.
Gulp.
Ji-na swallowed those bodily wastes without any sign of disgust.
She continued her service—her hand gently massaging my balls while her mouth sucked me off.
Schlick.
Soon, I came inside Ji-na’s mouth. Her mouth quickly filled with semen, which she slowly swallowed.
Honestly, it didn’t taste good, but she swallowed because she knew her oppa liked it.
Having swallowed all of her biological older brother’s semen, Ji-na pulled my cock out of her mouth.
“Didn’t you sleep well? Why do you look so tired?”
“Uh… I was doing it with noona for a while…”
“…Ah. Haah… Then are we resting today?”
Ji-na made a deliberately annoyed face, then spoke in a disappointed tone.
Does she really dislike noona that much? She gets irritated the moment noona is mentioned.
“No, let’s go today. I can sleep after we come back.”
My cock had recovered somewhat. I figured I could have sex a few more times.
Of course, not right now, so I told Ji-na to get ready to go out.
“Okay! Oppa, wake up and get ready too~! Hehe.”
The moment I said we were going out, Ji-na’s mood brightened instantly and she let out a silly laugh.
“…You really like this, huh.”
I was tired, but… she usually lets me use her mouth-pussy or pussy whenever I want, so I could at least do this much for her.
Besides, she was the younger sister I had been close to since childhood.
“I can wear anything, right?”
I picked any clothes from the closet.
A hoodie and black slacks.
I also put on a black cap.
Washing my hair was too much hassle.
I left my room and opened Ji-na’s door.
“Eh? I’m changing clothes.”
Ji-na was in the middle of changing.
On the bed lay the clothes and underwear she planned to wear today. She had already taken off her pajamas and was removing her underwear.
“Yeah, keep changing.”
Beep.
While Ji-na paused for a moment, I took out my phone and started recording.
“Huh? You’re going to film it? Upload it online?”
“I’m just filming for now. I’ll decide later whether to upload it or not.”
“Oh, okay.”
Even though her biological older brother was filming her naked body, Ji-na didn’t seem to mind at all.
She unhooked her bra and took off her panties.
Her bright pink labia and pink nipples were recorded clearly on my phone without any filter.
Still, my younger sister continued what she was doing without any concern.
She put on black lace panties and hooked her bra.
Then she slipped on an oversized t-shirt and short shorts that fully exposed her thighs.
The entire process of tucking the t-shirt into her shorts and slightly pulling it back out was captured on my phone.
Beep.
Recording ended.
The roughly one-minute video contained everything—Ji-na in her underwear and fully naked.
I’ll use it later when I get horny.
“Let’s go.”
I kissed Mom, who was resting on the sofa, and groped her breasts before leaving the house.
“…But where should we go…?”
“I already called a taxi!”
Whoa.
Seeing how proactive she was, she must have been really looking forward to this.
Ding ding ding. Ding.
We got in the taxi and headed to the Chanel store Ji-na wanted.
“Hehe…”
Inside the taxi, Ji-na kept giggling. Was it really that exciting?
I casually moved my hand and stroked her thigh.
“~♪”
Ji-na didn’t mind and continued giggling while looking out the window.
Swoosh. Swoosh.
I enjoyed the softness of her thigh, then slipped my hand inside her shorts.
“Hm? Do you want to do it? Want to put it in?”
Ji-na casually asked her biological older brother if he wanted to have sex inside the taxi and started to take off her shorts.
“No, I’m just going to touch.”
“Okay~.”
With Ji-na’s permission, I played with her pussy until the fare reached 9,000 won.
I rubbed the soft flesh covering her pussy, pressed her clit, and even slid my fingers into her soaking wet folds.
Schlick schlick schlick.
I roughly thrust my fingers, stirring up her pussy.
“Hmm~♪”
Of course, Ji-na simply hummed a carefree tune as if nothing was happening.
‘…It would be nice if she reacted a bit more.’
“Ji-na, regain the sensation in your pussy.”
“…Huh? Haa… Haah…?! W-wait… Haaak…♡ Oppa… your fingers…! Haaang…♡”
Ji-na, who had clearly heard my words, suddenly began feeling her pussy like a hypersensitive woman.
I had only moved my fingers gently inside her, yet Ji-na was so overwhelmed she couldn’t form a complete sentence.
“……”
Even though it must have been audible, the taxi driver acted as if nothing was wrong.
Actually, he kept glancing at Ji-na. He seemed turned on.
“Haah…♡ Haaauu…”
Schlick schlick schlick.
I roughly fingered her again.
The lewd sound of her love juices squelching began to echo.
“Haak♡ Haung♡ Haaang! Heut♡! Heut! Haaauuuuk…♡!!”
I felt a watery liquid spray onto my palm.
She had squirted magnificently and reached a huge orgasm.
Ji-na, who had never once felt pleasure from her pussy in her entire life, had zero resistance to it.
‘I didn’t expect this to work.’
I hadn’t known I could restore a sensation that had been missing.
Or maybe the nerves were all there, but she had simply stopped using them?
Either way, it didn’t really matter.
Schlick schlick.
“Haaauuuk…♡!! Heuk! Haaaaang♡♡!!”
She climaxed again.
Two or three rough thrusts and she came once. Since I was thrusting about three times per second…
That meant Ji-na was currently orgasming roughly once every second.
Because of Ji-na’s squirting, her shorts were already completely soaked, and the liquid that her shorts couldn’t absorb had wet the car seat.
“…We’ve arrived.”
—Trip ended. For auto-pay customers, please enter the meter amount.—
“Haah… haah…♡ Haaauuu…”
Having climaxed dozens of times, Ji-na stared with dazed eyes and let out sensual breaths.
“…Ji-na, let’s get out.”
“.Haah… Oppa…”
Since we had to exit from the right-side door, Ji-na had to get out first.
That was why I tried to bring her back to her senses, but…
“Ji-na…?! Let’s get out first!”
Ji-na suddenly pounced on me inside the car.
Overwhelmed by the intense pleasure she had never experienced before, Ji-na had gone into heat.
Still, she hadn’t forgotten she had to obey me—she bit her lower lip, opened the car door, and stepped out.
I followed her.
“Oppa. Let’s do it…♡ Okay? Just once… No, twice… Just as many times as you want…♡ Hm? Oppa~…”
Right after getting out of the car, she grabbed my cock and rubbed her breasts against my upper body.
Ji-na had inherited her mother’s genes and had large enough breasts to be called busty. Feeling those big breasts pressing against me made it hard for me to hold back.
“……”
Showing Ji-na’s lewd behavior to everyone around us didn’t feel right.
There were no motels nearby, of course.
If there was no space, I could just create one.
There was a hamburger place nearby, so I took Ji-na there.
I brought a female employee with us and entered the men’s restroom.
I told the employee not to let any men enter the restroom.
I sat Ji-na down on the toilet.
“Hehe… Oppa… That felt so good just now…♡ I want to feel it again…”
Saying that, Ji-na took off her shorts and panties and spread her pussy open with both hands.
“Ji-na…”
She looked exactly like a meat urinal begging for cock.
Seeing my younger sister’s lewd display, I, now fully erect to the limit, thrust into her pussy.
“Haaauuuk…♡!!”
Although I usually prefer expressionless sex… I couldn’t eat the same thing every day.
“Haang! Haaang♡! Haaauuuut…♡♡!”
Ji-na’s pussy was not just wet—it was gushing with love juices.
That was why I could insert immediately, and why she felt only pleasure instead of pain.
My cock continued to push deeper…
“Heuk…♡?!”
Soon it reached the entrance of her womb.
The moment she felt the soft texture of her cervix, Ji-na’s lower body twitched.
She squirted a little…
Apparently just having it all the way in had made her cum.
How lewd can my little sister be?
If I hadn’t taken her in, what would have happened to her?
I didn’t really want to imagine it.
“Oppa haa…♡ Oppa…♡ Kiss… give me a kiss…”
Her slurred speech and the way she begged for a kiss were so cute that I couldn’t refuse.
“Chu… slurp… haam…”
It wasn’t the innocent family kiss between siblings, but the deep kiss of lovers.
My cock was buried inside my little sister’s pussy.
And then—
Pow! Pow! Pow!
“Hiiik?! Haak♡! Haaaak♡!!”
I enjoyed my little sister’s pussy.
Since my little sister also seemed to be enjoying my cock, this was incestuous lovemaking.
“Hiiiggguuuuk♡?!!”
With one powerful thrust, Ji-na squirted and convulsed in a spectacular orgasm. The lively, cute little sister from just moments ago was nowhere to be found.
She was now nothing more than a whore craving cock.
“Hoo! I’m cumming!”
“Haak! Haak! Oppa!! Cum…! Cum inside me…♡!”
Ji-na wrapped her legs around my waist so I couldn’t pull out.
Not that I planned to pull out anyway.
“Hoo…!”
“Haaauuuuuk♡♡!!”
My semen slammed into the depths of her womb—places my cock could never physically reach.
She should have felt intense pain, but Ji-na’s lewd body only felt pleasure—an overwhelming ecstasy she had never experienced in her twenty years of life.
My ejaculation volume was on a completely different level from ordinary men, so Ji-na’s womb was filled to the brim with my semen.
“Haaau… haauuut…♡… Haaaa…”
Ji-na kept expanding her chest as she breathed heavily.
Only after that one massive orgasm did most of her sexual desire subside. Ji-na gradually regained her senses.
“Hoo…”
Regardless, I stayed buried inside her pussy, savoring the afterglow.
Every time Ji-na breathed out, her pussy tightened around me, making me cum a little more.
“Haah…♡ ………”
The sensually breathing Ji-na eventually grew quiet.
Her face was bright red, and she couldn’t look me straight in the eyes.
“…Forget what just happened.”
Even though an overwhelming wave of pleasure had suddenly hit her, the fact remained that she had surrendered to lust.
That was why Ji-na couldn’t lift her head from the embarrassment of her own lewd behavior.
She felt no guilt whatsoever about having had sex with her biological older brother.
“Why? It was cute.”
“Ah~ah! Forget it! Forget it!!”
Ji-na, now throwing a tantrum, had returned to her usual lively younger sister self.
“Hoo… heut♡… Are we doing more…?”
Ji-na asked with a hint of expectation in her voice.
She really wanted the bag, but… she wanted her older brother’s cock even more.
“We’ll do it when we get home. And stop feeling sensation in your pussy now.”
“Ehh… It felt so good though…”
When the sensation in her pussy disappeared, Ji-na pouted but didn’t openly complain.
“Hoo… Anyway, that was good, Ji-na.”
“Well, I’m glad you enjoyed it. Umm… I can… do that kind of thing sometimes too… right?”
She rolled her eyes anxiously, worried I might not allow it.
“Okay. I’ll let you do it sometimes.”
I also sometimes crave this kind of sex.
“Hehe. Love you, oppa~.”
Our sibling relationship had originally been close thanks to friendship, but somehow it was gradually turning into something more like lovers.
The passionate sex after regaining sensation had created a bond of affection, but Min-jun had no idea.
We roughly cleaned up and left the restroom.
The female employee’s face was red—probably because she had heard Ji-na’s moans.
“Thank you for your help.”
I thanked her while groping her ass.
“N-no… It was my job…”
“Then we’ll be going now.”
“Yes… Have a nice day~.”
I gave her breasts one last squeeze before leaving the store.
Then we entered the Chanel store, the same place where we had gotten off the taxi.
“Welcome~.”
Various products were displayed throughout the store, along with a few mannequins.
There were only one or two customers—fewer than I expected.
“Wow… It really does feel luxurious…”
“…Oppa, you don’t know Chanel? It’s a famous luxury brand…”
“…I don’t?”
“Well… You’ve probably just been jerking off in your room all day, so of course you wouldn’t know…”
Because she said something cheeky, I groped her breasts.
Since she was wearing a thin t-shirt, the sensation of her breasts was transmitted quite clearly.
She was wearing a bra, though…
“Oh my, you two seem very close. Are you looking for anything in particular?”
A woman who appeared to be in her early thirties approached us.
Dressed in office attire, she seemed to be the store manager.
I continued groping Ji-na’s breasts as I looked at her.
Sensing my gaze that said “You talk,” Ji-na stepped forward and began describing the item she wanted.
“Do you have the Chanel Boy Belt Bag?”
Boy Belt Bag?
Was that a men’s item?
“Ah… We’re out of stock for that one… I’m sorry. If you tell me your preferred price range, I can show you what we have in stock.”
“Uh…”
Ji-na had been planning to ask for a bag worth about 2.7 million won, so she was about to say that price.
But the person actually paying was her older brother.
Since it wasn’t her own money, she felt awkward saying it and looked at Min-jun.
“Hmm… Price doesn’t really matter.”
After all, around 30 million won came in every day.
…Though weekends were probably off.
“Oh my… As expected of Min-jun-nim… We actually have one item left in stock from the popular line… Would you like to see it?”
“Yes. Please show us.”
The female staff member led us to where the bags were displayed.
“Eh… That one…?!”
The staff walked toward a particular bag, and Ji-na’s eyes widened in surprise when she saw it.
“This is the Classic Medium Caviar with gold hardware, in a shoulder bag style. You seem to recognize it, miss. Ho ho.”
Squeeze squeeze.
I kept groping Ji-na’s breasts and asked her.
“Do you know what that is?”
“U-uh… I know it, but…”
Her eyes were filled with excitement, yet her tone sounded worried.
Is it expensive?
“…That one costs over 10 million won…”
Ji-na said in a slightly deflated voice.
The bag she had originally asked Min-jun to buy was around 3 million won.
Asking for a bag three times more expensive now was difficult even for Ji-na.
“How much is it?”
Squeeze squeeze.
Groping over the bra wasn’t enough, so I slipped my hand under her t-shirt and inside her bra to fondle her bare breasts.
The silky soft skin and squishy flesh felt incredibly good.
“Eut… Oppa, be gentle with my nipples.”
I pinched her nipple once—hmm, it seemed to hurt.
“This item is currently priced at 18.9 million won. It was actually reserved, but if Min-jun-nim wants to purchase it, I can sell it to you.”
Flinch.
At the mention that it was reserved, Ji-na flinched.
The thought that this might be her only chance made her anxious.
To act cute toward her oppa, she slipped her hand into Min-jun’s pants inside the store and started stroking his cock.
“Oppa~…♡”
She spoke in a coquettish voice, but her intention was so obvious it made me chuckle inwardly.
“I’ll take that one.”
While fondling my little sister’s bare breasts and receiving a handjob, I told the female staff member.
“Yes. Then I’ll assist you with the 18.9 million won payment~.”
The staff member thoroughly wrapped the bag with protective packaging and shock-absorbing materials that appeared from somewhere, then headed to the counter.
“Thank you, oppa!”
Seeing my little sister smile brightly was so cute that I lightly pinched her nipple.
“Heut…♡ Hey… I told you to be gentle…♡”
Squeeze.
As if in revenge, she gripped my cock tightly.
Pfft.
“Let’s go pay.”
“Okay.”
Ji-na let go of my cock and grabbed my ass instead.
Why is she touching a guy’s ass?
She kept squeezing it…
I had only ever touched, never been touched, so it felt strange, but I let it be.
It was probably Ji-na’s way of showing gratitude.
“Thank you for shopping with us~!”
“Yes.”
Squeeze.
I reached out and groped the staff member’s breasts.
“…Would you like to put it in?”
“Yes. Just once.”
“Of course, I’ll gladly offer it. Fufu.”
She lifted her tight skirt, exposed her ass, then tore her own stockings and pulled her panties aside to reveal her pussy.
“Are you a virgin?”
“No, I have a husband.”
“You have a husband and you’re still okay with having sex with me?”
She seemed way too willing.
“When Min-jun-nim wants it, of course I should offer it. It’s also a form of business hospitality, you could say?”
“Sex hospitality…?”
“Yes♡. I would have offered my daughter if I had one… Unfortunately, I don’t have children yet…”
She looked to be in her thirties, but even if she had a daughter at that age, I had no intention of touching her.
“It’s fine. I’ll just use your pussy.”
“Yes. Please use me however you like.”
With my left hand still fondling Ji-na’s bare breasts, I aligned my cock at the staff member’s entrance with my right hand.
I grabbed her ass and thrust straight in.
“Does it feel good?”
She didn’t seem hypersensitive; the staff member remained composed.
“It feels good…”
“Oppa, want me to lick your asshole?”
“Hoo… Where the hell did you learn that…”
“I started searching for ways to please you ever since I began handling your sexual needs, oppa.”
“Hoo… Just once then.”
“Okie~.”
Ji-na knelt behind me.
She pulled down my pants and underwear in one go and buried her face in my ass.
Lick.
The moment Ji-na’s tongue touched me, a shiver ran down my spine.
Ji-na licked my asshole while I received the staff member’s sexual service.
Because I had to move my hips, Ji-na’s face kept bumping into me.
That sensation was strangely arousing too.
The staff member’s pussy had been used before, but the idea of a married woman offering sexual hospitality was arousing, and Ji-na’s rimjob felt better than expected, so I came quickly.
Schlick.
“Hehe… Are you satisfied?”
“…Not yet.”
I switched to face-to-face standing position with the staff member.
I kissed her, roughly ravaging the inside of her mouth while moving my hips.
The woman who was taking another man’s semen deep inside her while kissing—not her beloved husband with whom she had promised to spend her life—responded eagerly to my tongue.
I kissed her and freely tasted the inside of her pussy. Only after my third ejaculation did I pull out.
“Are you satisfied now?”
Her calm tone, as if she hadn’t just had sex, was… lewd.
Semen was flowing from her pussy, forming a white puddle on the floor. Her mouth was a mess of saliva.
Her breasts were exposed, marked with red handprints.
“Yes. I’m satisfied… Hoo…”
Ji-na stopped rimming and helped me put my pants back on.
Only then did the other people in the store stop glancing at us and resume browsing the products.
What I did might be considered natural, but it was still lewd, so it was inevitable that eyes would be drawn.
I told the staff member not to take birth control, and two months later she would learn she was pregnant.
Her husband happily believed the child in his wife’s belly was his.
Seeing her husband like that, the wife felt no guilt and celebrated with him.
The child who grew up that way would later become a fine adult woman… and get fucked and impregnated by Min-jun.
But that is a story for the distant future.
