Little Sister's Sexual Processing Blowjob
Chaerin flicked out her small tongue.
Slurp.
Her hot, soft tongue dragged a long, continuous lick from the root of my cock all the way up to the tip of the head.
“Oh…”
Every hair on my body stood on end. The sensation of a woman’s tongue—something I was feeling for the first time—made me flinch without meaning to.
Just that single stroke of her tongue sent all the blood in my body surging straight down to my groin.
Encouraged by my reaction, Chaerin gave a brief, smiling look with her eyes. Then her right hand gently wrapped around the rigid pillar.
My cock was so large that her right hand could only encircle half of the shaft.
“Alright… I’ll do the sexual processing.”
Unable to hide the excitement in her voice, Chaerin parted her soft lips and slowly took the head into her mouth.
Schlick.
A hot, wet sensation enveloped the glans. It felt as if only the head had slipped into an entirely different space—one I had never known, and an incredibly pleasant one.
Chaerin began clumsily sucking on the head. She didn’t seem to know how to work her tongue, simply mouthing at the glans she had taken in. Even so, it was more than stimulating enough.
The pleasure of a woman’s mouth was warm, soft, and tight.
That tiny space, far too small to properly take my cock, delivered overwhelming pleasure all the same.
I still couldn’t believe that the same mouth that had been so tsundere and prickly was now sucking on my cockhead.
I smiled inwardly and gently stroked Chaerin’s light purple hair.
“Mmph…”
Greedy, she tried to swallow my cock even deeper. She hollowed her cheeks until they caved in, creating a near-vacuum as she sucked me in.
Thanks to that, my cock slid about halfway into her mouth. Beyond that, though, seemed impossible.

Her throat, completely inexperienced, was putting up firm resistance.
“Nngh…!”
The head must have struck her soft palate; Chaerin stifled a gag and let out a pained moan. I stroked her hair and pulled my cock free for a moment.
Looking at my cock glistening with her saliva, Chaerin wore an embarrassed expression.
“I-It’s my first time… I haven’t formally learned blowjob sexual processing yet. I’ll do better next time… Sorry.”
“It’s fine. It’s your first time, after all.”
If anything, I found her clumsy efforts endlessly adorable—and arousing.
My twin little sister, only just beginning to learn the taste of a man. The thought that I could train her however I liked made my desire to dominate surge.
Chaerin adjusted her posture. This time she began gently stroking the shaft with her right hand while sucking the head with her mouth at the same time.
She didn’t stop there. In that brief interval she seemed to have figured out a lot about fellatio; she began lightly licking the underside of the head with the flat of her tongue.
Pleasure attacking me from three places at once made the world spin before my eyes.
Every time her saliva-slick hand slid up and down the shaft, my fist clenched on its own.
The longer it went on, the better her mouth felt.
At first her tongue had been still, but now it had fully come into its own. The technique of teasing the underside of the urethra with the tip of her tongue was no joke.
Her slick tongue and the soft flesh of her cheeks clung wetly to my cock.
“Haa… Chaerin…”
“Mmph, chuuup, chuuup.”
At the sound of my voice, Chaerin lifted her head and looked up at me.
Lips glossy with saliva and my precum, eyes hazy with pleasure, cheeks flushed red from the steam.
The moment I saw that cute yet lewd face, the urge to cum surged upward at terrifying speed.
I wanted to completely defile this adorable girl and make her mine.
I wanted to yank away the towels covering her chest and pussy right that second.
“I’m gonna cum.”
Chaerin’s eyes went wide at my words. I gently held her head and lightly thrust my hips, pushing deeper into her small mouth.
Spurt! Spurt!
Strength flooded into my thighs of its own accord, and pleasure hot enough to cook my brain shot from my cock.
The satisfaction of dumping my load into a woman’s mouth amplified the pleasure even further.
“Mmph!? Mph! Nngh…!”
The massive volume of cum filled her narrow mouth, and Chaerin trembled as if she had been ambushed.
Because I had pushed my cock all the way to the entrance of her throat, she momentarily couldn’t breathe and slightly opened her mouth.
The second her lips parted, the cum that had filled her mouth spilled out along the corners of her lips. She closed her mouth again too late.
In the end, not knowing what else to do, Chaerin spat the remaining cum in her mouth out onto her right hand.
Looking at the thick load she had spat out with a “Bleh,” Chaerin suddenly wore a thoughtful expression.
Was she maybe wanting to swallow the cum?
Why the cum? The thought crossed my mind, but I quickly understood. This wasn’t ordinary Earth—women’s libido here was far greater than men’s.
The sight of Chaerin wanting to eat the cum her oppa had just shot was insanely hot.
“You gonna eat that cum?”
I asked purely out of curiosity, with no special intent. Caught red-handed staring at the cum, Chaerin looked startled.
“W-What are you talking about?! I wouldn’t eat your cum even if you paid me. I washed you, so we’re done, right? I’m leaving first!”
Chaerin blustered loudly, hastily rinsed the cum off her palm under the water, and fled the bathroom.
As she escaped the bathroom like she was running away, her ass swayed lewdly.
And I saw it—a single strand of clear fluid that dripped from between Chaerin’s thighs with a soft plop.
Left alone in the bathroom, I looked at my reflection in the mirror.
Despite Chaerin’s service, this massive cock showed not the slightest sign of softening; it still stood proudly at full attention.
Uncontrollable stamina. I had already cum twice today, yet it still felt like it wasn’t enough.
Only after dousing myself in cold water for a long while was I finally able to leave the bathroom.
Once I changed into the fresh underwear and pajamas Chaerin had folded and left outside the bathroom, the smell of ramen hit my nose.
On the small living-room table sat two bowls of steaming ramen, steam still rising thickly from them.
“Oh, ramen?”
Mistaking my words for a complaint, Chaerin grumbled.
“Hey, I didn’t know you were getting discharged today. I didn’t go grocery shopping, so this is all there is for dinner. I’ll make something better tomorrow. Sorry.”
“Do you usually eat a lot of ramen?”
“While you were in the hospital I ate a lot of ramen.”
The moment I heard that, something in my chest tightened.
Someone apologizing for not being able to make me a delicious meal. It was completely moving.
And thinking of Chaerin surviving on ramen alone the whole time this body had been in the hospital made my heart ache a little. We probably didn’t have much money.
I met the eyes of Chaerin sitting across from me and spoke from the heart.
“Anything you make is good. I’ll eat it happily. Thanks.”
“W-What’s with the sudden embarrassment? Just eat already.”
Chaerin answered gruffly and turned her head, but I saw the tips of her ears flush slightly red.
While I sat still, Chaerin bustled around the kitchen and set some kimchi down in front of me.
Hungry, she slurped up the hot noodles with gusto.
Her small lips, stained with bright-red ramen broth, entered my field of vision. Instantly the earlier pity vanished without a trace, and lust reared its head again.
It still didn’t feel real that those same small lips currently eating ramen had just been sucking my cock.
The way her lips moved as she sucked in the noodles overlapped perfectly with the way they had sucked on my cockhead.
The scene from the bathroom earlier came flooding back in vivid detail. Just watching her eat ramen was enough to make my lower body grow heavy again.
I couldn’t tell whether the problem was that Chaerin was too pretty and lewd, or that my lust was simply too strong.
“Hey.”
I was half-eating my ramen while stealing glances at Chaerin’s lips when she spoke first.
“I saw earlier—your phone kept going off. If you don’t remember anything, don’t bother replying. Those heat-crazed bitches just make things hard for you… tsk.”
“Ah, that. It surprised me a bit. Was I originally that popular?”
“Popular? What popularity. It’s just because men are rare. You think they actually like you? Don’t get the wrong idea.”
Chaerin snapped as she stirred her noodles with her chopsticks. She looked exactly like a little kid fretting that someone might steal her toy, and I couldn’t help smiling.
Was she jealous, maybe?
When the meal ended, Chaerin handed me a small medicine packet, saying it was from the hospital. Medication for aftereffects of the car accident, she explained.
Without much thought I swallowed a few pills with water. Whether it was my imagination or not, my head felt a little clearer.
After confirming I had taken the medicine, Chaerin stood up from her seat.
“You just got discharged today, so rest a bit.”
She had already handled my sexual processing, attended me in the shower, and even made ramen. Just resting after all that pricked my conscience, so I answered,
“I’ll do the dishes.”
Clang!
The bowl in Chaerin’s hand slipped and hit the floor with a loud crash. She stared at me with an expression of pure disbelief.
“Did you… hit your head again or something?”
Remembering my amnesia, she pushed my back with a mixture of worry and irritation.
“What kind of man does the dishes?! That’s women’s work. You go lie down right now!”
Her firm hands guided me until I plopped down onto the mattress.
“Stop talking nonsense and just go to sleep already. That’s how you help.”
Worry hidden inside her gruff tone.
Along with the soft give of the mattress, a quiet laugh slipped out of me.
So being a man here just means getting waited on hand and foot.
It was sweet as honey.
Just then, as if something had occurred to her while she washed the dishes, Chaerin spoke.
“Oh, right. We start academy on Monday.”
“Academy? What academy?”
“You forgot that too? You must have really smashed your head hard.”
Chaerin clicked her tongue, yet her voice still sounded somehow excited.
“Marriage Academy. Search for ‘Female Academy’ on the internet.”
