“Eh… why…?”
Masanojo’s penis was still erect.
Kyoka fell into confusion for what felt like the umpteenth time.
According to the medical books she had studied, after a man ejaculated, the erection should subside immediately, and the time required for the next erection was at least several months even in the fastest cases.
The average number of times an adult male could reproduce in a year was about two to three times.
Even for young, energetic teenagers, four to five times was the limit.
Once they reached their thirties, the number dropped drastically, and being able to get an erection once every few years was considered fortunate.
That was supposed to be the cycle of male erection and ejaculation.
But the thing in front of her right now… Masanojo’s penis was clearly erect.
And it wasn’t just any erection.
It was a massive erection that looked ready to pierce the heavens.
What was going on?
Were the medical books she studied just medical books (lol)?
Had she been learning false knowledge?
“Haa… haa… haa…”
Masanojo’s pained breathing pulled Kyoka back to reality.
His face was flushed and still looked like he was suffering from the erection.
“…Masanojo-kun.”
“Twitch!”
When Kyoka called his name, Masanojo’s shoulders jerked.
He looked somehow frightened.
Kyoka spoke to him gently.
“It’s okay.
Don’t be scared, all right?”
Masanojo slowly nodded in response to her voice.
“You got hard again… Does it hurt?”
He nodded once more.
“I see.
It got painful again, huh?”
Kyoka placed her hand on his cock once more.
“Hyuu!”
“It’s okay.
Leave it to Onee-san.
I’ll make it feel better right away.”
Saying that, she began stroking his cock.
It was even larger and harder than before.
Kyoka gently caressed it.
“Tch!
Ah… nn… ah… aaahh…”
Just like earlier, Masanojo writhed.
But something seemed off.
He looked even more pained than during the previous erection.
His face was twisted in suffering, and tears welled up in his eyes.
Seeing that, Kyoka grew confused.
What was wrong?
Why was he suffering so much?
Every time she stroked his penis, Masanojo twisted his body, closed his eyes, and grimaced.
Maybe she was doing something wrong.
Doubt about her own actions began to grow.
When Kyoka stopped her hand, Masanojo’s shoulders relaxed as if he had been freed from the pain.
But his expression was still full of suffering, and he looked at her face as if seeking help.
Stopping the stroking freed him from the pain.
Kyoka fell into a dilemma.
How could she relieve his erection without stroking his cock?
How could she stimulate his cock without using her hands?
Hands… hands?
Then a revelation struck her.
That’s right — using her hands was the problem.
Even a massage becomes counterproductive if done too much and damages the skin.
So she should use something softer than her hands.
Realizing that, Kyoka immediately put it into action.
“Wait just a moment, Masanojo-kun.
Onee-san is going to help you right now.”
“…Eh?
What does that mean…!!??”
Kyoka brought her face close to the cock she was holding with both hands and, without hesitation, took it into her mouth.
“!!
Ah… aaaaaaaaaahh!!”
Masanojo arched his back hard, his mouth opening and closing.
Seeing that reaction, Kyoka was convinced her judgment had been correct.
“Nchu… slurp… slurp… slurp… nn… Masanojo… slurp…-kun… slurp.
I’ll make it… slurp… feel better for you now… slurp.”
She smeared her own saliva all over his penis like massage oil.
She coated the shaft, the glans, the ridge — everything — with saliva and gently massaged it with her tongue.
The soft stimulation that hands could never achieve gave Masanojo’s cock an indescribable pleasure.
“Ah… ah… ah… a… aaaaaaaaaahh!”
Letting out wordless cries and drooling heavily, Masanojo moaned while Kyoka looked up at him.
Even so, she never stopped sucking on his penis.
“Slurp… nchu… chu… zchu… nechu… Masanojo-kun… zchu… Does this feel good… slurp…?”
“Nnaaah… ah… ah… aaahh…”
“Slurp… slurp… zchu… Hey, tell Onee-san… slurp…?”
“!!
Nnaaa… ah… aahh… i-it feels… good…”
“Slurp… slurp… Un?”
“Nnah… it feels good… it feels good…”
“Slurp… I see… slurp… slurp… It feels good, huh…?
Slurp”
“It feels… good… it feels good!!”
“Slurp… I see.
Onee-san is happy too… chu”
“Aaaaaaaaaahh!!”
The obscene sounds leaking from her mouth gradually made Kyoka herself more and more aroused without her noticing.
By putting his cock in her mouth, she was making the boy in front of her writhe in such pleasure.
She wanted to make him feel even better.
More, more, more, more, more…
In proportion to her rising emotions, the movements of her mouth on his cock grew more intense.
Slurp… slurp… nchu… zuzuzu… nchuuuu… zchuu… nn… nchu… chu… chu… zchu… buchu… zchuu… nnchu… slurp… slurp… nchu…
She attacked him fiercely with her mouth, moving her head back and forth, licking and stimulating his cock with her tongue.
There was no technique — only the pure desire to make Masanojo feel good.
That alone was what moved Kyoka now.
Nchu… zuzuzu… slurp… slurp… nchu… chu… nchu… chu… chu… zchu…
“Ah… aahh… aaaahh!”
In response, his cock also twitched and convulsed repeatedly.
“Aahh… ah… ah… Kukon-san… ah… aahh… Tsukumo… ahn…”
With a slurred, childish tongue, Masanojo called out her name.
“Kukon-san… Tsukumo…-san… aahh…”
“Slurp… slurp… nnchu… Call me… Kyoka…”
“Ah… nnah… ah… ah…”
“Nchu… Kyoka… nchu… Please, call me Kyoka… slurp”
“Ah… ah… aahh… Kyoka…-san…”
“Slurp… nchu… Yes…”
“Aaaahh… Kyoka-san… Kyoka-san… Kyoka-saaan!!!”
Being called by name filled Kyoka’s heart.
The fact that the boy in front of her recognized her existence gave her an indescribable joy.
Slurp… nchu… zuzuzu… nchuuuu… zchuu… nn… nchu… chu… chu… zchu… buchu… zchuu… nnchu… slurp… nchu…
“Ah… ah… ah… aaaahh… aaaaaaaaaahh!!”
Under Kyoka’s even more intense oral assault, Masanojo couldn’t hold back and pressed down on her head.
Reaching his limit, his cock was driven to ejaculation by the intense pleasure.
“Aaaaaaaaaaaaaaaaaahh… Kyoka-saaaaaaan!!!”
Bobyu… byurrrrrrrrr… byurrrr… bobyubyubyuu… byurrruu…
A massive amount of sperm was poured into Kyoka’s mouth.
The semen that couldn’t fit inside overflowed, but because her head was being held down she couldn’t move her face, and it flowed straight down her throat.
“Nguh… nn… nn…!
Nguh… gulp… gulp… gulp”
Kyoka swallowed with audible gulps.
Watching her like that, Masanojo continued pouring out a volume of sperm that didn’t seem possible for a second ejaculation.
“Nguh… nn… gulp… gulp… gulp… …Puhah.”
After the ejaculation ended, Masanojo pulled his cock out of her mouth.
Kyoka opened her sticky, semen-filled mouth wide and clearly showed it to him.
“…Pwah.
Yes, you released a lot.
Good boy, good boy.
Chu”
As if praising him for a job well done, Kyoka kissed his penis.
And then, somehow… even after releasing such a massive amount of sperm, Masanojo’s cock regained its hardness as if reacting to her kiss.
“…Ugh…”
Masanojo looked down in embarrassment.
His cock stood rock-hard once more.
The glans was flushed red, and the veins running along the shaft pulsed powerfully with each heartbeat.
The tightly, tightly erect penis looked painful even from the outside.
“It got big again, huh?”
Masanojo’s face turned bright red at her words.
Kyoka gave him a gentle smile.
“It’s okay.
Onee-san is right here with you.”
Saying that, she quietly took his cock into her mouth once more.
“Nchu… chu… Onee-chan is here… chu… so you don’t need to worry… slurp…”
“A-Aahh… aaaaaahh!”
“Slurp… slurp… nchu… slurp… Onee-chan will… slurp… help you… okay…?
Slurp… slurp… nchu…”
Kyoka’s oral assault began again.
In order to relieve Masanojo’s erection, Kyoka sucked his cock over and over and over again, until he was finally satisfied.
