I thought it had ended as nothing more than a simple incident.
An incident caused by curiosity.
An incident caused by accidentally activating Erogenous Stimulation.
That's what I thought.
But then…
“Oppa… Can I touch your cock?”
Ever since that day, Sophia had started seeking out my cock.
====
I was stroking Sophia's head as usual while she was feeling depressed, when she suddenly said she wanted to touch my cock.
“…What?”
“I said, can I touch your cock? Uu… Why are you making me say it twice when it's so embarrassing!”
“No, why are you trying to touch my cock when it's embarrassing?”
“It's just… It felt good when I touched your cock that time…”
So that's what it was.
Erogenous Stimulation.
That's the problem.
When my cock was touched, I instinctively activated Erogenous Stimulation, but I shouldn't have.
“Huh? Stroking my head feels like it's not enough... Can't I touch your cock? Please?”
“Sophie… You have Siwoo.”
“Uu… This is just to cheer me up! Besides, who was it that made me upset in the first place!”
Ah… Is that how it happened?
Without realizing it, I seem to have trained Sophia.
Whenever Sophia felt depressed, I used Erogenous Stimulation to stroke her,
so she came to crave sexual pleasure whenever she felt down.
So even though she knew touching my cock was a lewd act, her body demanded it.
Can't be helped. Since I made her this way, I have to take responsibility.
It's absolutely not because I have ulterior motives.
I had no intention of pursuing the main heroine in the first place.
“Ha… Fine. Here.”
When I took out my cock, Sophia reached out and started touching it as if she'd been waiting.
“Hehe…! This is weird. Why does touching a cock feel so good?”
“That's because you're a pervert, Sophie… Aah! You!”
I made one joke, and Sophia suddenly grabbed my balls.
I screamed at the unexpected pain.
“You're the pervert, Oppa! Shut up before I tell Dad!”
Apparently, she still held what had happened that time against me.
Well, understandably so.
Since I was the one at fault, I decided to keep my mouth shut.
Instead, I took Sophia to the bed.
“W-what are you doing?”
“Here, isn't this more comfortable?”
I sat on the bed, lay back against the wall, and placed Sophia on my stomach.
I wedged both knees between Sophia's legs and forced them apart,
making the one-piece dress she was wearing slide down to her hips, exposing her thighs.
As I lowered Sophia like that, my cock came into contact with the space between her thighs.
I could feel the soft fabric of her panties.
In that position, I wrapped one arm around Sophia's shoulders and stroked her head with the other.
Sophia flinched several times, but soon seemed to adjust and began caressing my cock while letting out little nasal moans.
“Hmm-♪ Hm-♬ This is definitely much more comfortable. Hehe.”
“Right?”
Sophia, nestled in my arms, carried the scent of a girl her age.
When I brushed back her hair, I saw the snow-white nape of her neck.
Tiny beads of sweat had formed, perhaps because Erogenous Stimulation had aroused her.
I stuck out my tongue and licked them.
“Haaang! …W-what are you doing?”
“I was wiping off your sweat.”
“……???”
Sophia didn't seem to notice.
Whew… I nearly let my lust get the better of me.
Sophia was the main heroine.
I mustn't touch the main heroine.
I had to hold back.
But did I really have to?
This time, I lowered the hand around her shoulders and wrapped it around her waist.
Sophia's waist was incredibly slender.
I leaned forward and rested my face on Sophia's shoulder.
Then Sophia's cheek touched mine.
Sophia's face was already flushed.
With my free hand, I caressed Sophia's thigh.
Her thigh was wet with sweat too.
I could feel her panties gradually growing damp against my cock.
As Sophia caressed my cock, little moans began slipping out of her.
“Haa… Hmm…”
“How is it…? Haa… Feels good, right? Hmm…”
“Huh? Hng… Am I good at it? Hmm?”
Sophia leaned into me, as if asking me to praise her.
As she did, she slowly began moving her hips.
She didn't seem to realize it herself.
She was moving her hips on instinct.
“Sophie, hold my cock like that and move your hand up and down.”
“Haa… Like th—this?”
“Good. But grip it a little tighter. Yes, like that.”
“Hmm… Like this… Haa… I'm supposed to stimulate it here… right?”
“Ugh, keep going just like that.”
“Hmm…♬”
What a frightening girl Sophia was… You only had to teach her one thing for her to learn ten.
Sophia's slender fingers gripped my cock and stroked it, stimulating the glans,
while Sophia's pussy was soaking my cock from above.
“Ah! Oppa! Haa… You're turned on, right? Right?”
When pre-cum began leaking from the pleasure, Sophia was delighted.
“That's right, Sophie. You got me all turned on.”
“Hehe…! I see! Hehe… Then now, the… Haa… semen…”
“Okay, that's enough. That wasn't what this was for in the first place.”
“No! I feel good too, so you can cum too!”
If I came like this, we'd really cross the line,
and it felt like I was going to go all the way, whether she was the main heroine or not,
so I tried to stop,
but Sophia refused.
“Come on, hurry and cum! Hmm? Come on!”
As if she wanted to make me cum before I could refuse, Sophia gripped my cock harder.
And now she began rocking her hips hard enough to make the bed creak.
“Haaang… Ah, ah, aaah…! Hurry…! Ngh…”
“Hng… It feels so good! Ah, haah, Oppa too! Haa…”
As her pussy and clit rubbed against my cock, Sophia seemed to get aroused too; her moans grew louder and finally burst free.
The room filled with lewd smells and sounds.
“Oppaaa… Haaang! Please! Haaaa… Hmm? Togetherrr!”
In the end, I couldn't hold back and ejaculated,
“Haaaaaaang!”
and Sophia reached climax at the same time.
“Haa… Haa… “
“Ha… Sophie, you…”
“Hehe… I made you cum with me, Oppa, haa… right?”
Sophia, having finally made me ejaculate, smiled as if she'd won.
Then she fiddled with the semen on her dress.
“So this is… semen…”
Then she promptly brought it to her mouth and swallowed it.
“…Sophie?”
“Blegh! It tastes awful!”
“Of course it does… No, why did you eat that?”
“Just… I thought it might taste good since it was yours… Hehe.”
“You really are…”
That completely killed the mood.
Right before ejaculating, I had been ready to take it all the way, but now I was thinking clearly.
In other words, this was the so-called post-nut clarity.
Rather than pounce on her, I lay down on the bed and pulled Sophia into my arms.
Sophia nestled in my arms without resisting.
We spent some time like that,
then I eventually came to my senses and washed the soiled bedding and clothes.
====
Similar days continued after that.
Whenever Sophia was having a hard time, I'd take out my cock, and whenever I came, she'd climax…
A month passed like that.
Recently, touching my cock no longer seemed enough for Sophia, and she'd started sucking it the week before.
And starting today…
“Yawn… slurp, lick, suck, haa… lick”
she'd started giving me morning blowjobs, just like this.
“Ah! You're awake? Hehe… Feels good first thing in the morning, right?”
It's a really strange feeling, having my cock sucked first thing in the morning.
I told her it felt good and stroked Sophia's head.
Sophia was delighted and devoted herself to sucking my cock.
At first, Sophia had held my cock in her mouth and not known what to do,
but now she'd gotten so good at sucking it that if I let my guard down, she'd make me cum immediately.
“Ugh, Sophie, I'm going to cum!”
When I filled Sophia's mouth with cum, she savored it, rolling the semen around with her tongue.
At first she'd said it tasted bad, but recently she liked it, saying it had a strange addictive quality that somehow reassured her.
It was probably an effect of Erogenous Stimulation.
“Gulp-!”
“Haa… I swallowed it all. Hehe.”
Seeing Sophia enjoy having sucked my cock more than I did turned me on immensely.
After pulling Sophia closer, I hugged her from behind and fondled her breasts.
“Eek! O-Oppa! Don't!”
I pretended not to hear her and didn't stop.
Perhaps because she was destined to become a saint, the maternal allure her breasts gave off was powerful and beautiful.
“Haaang… I said stop!”
Sophia escaped from my arms. Her nipples were erect, perhaps aroused even by the brief caress.
“I-I'm embarrassed! Honestly…”
Apparently she noticed it herself, because Sophia covered her breasts and erect nipples with both arms.
“You're not embarrassed to suck my cock?”
“Th-that is that! This is this!”
With that, Sophia ran away.
I kept trying to sneak in a caress, but surprisingly, her defenses were high.
She sucked my cock but wouldn't let me touch her—is this some new form of torment?
Still, if I kept knocking, she'd eventually open up.
I think I can conquer her before we leave on our adventure.
The main heroine?
I'm going to take her for myself. I'm too horny to stop.
