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.
