The Petrification Hero's Childhood Friend (1)
Placing my monstrous cock against her lower belly made Serin flinch. The heat she felt there seemed to shock her, and she began breathing in rough, ragged gasps.
My two fingers kept pressing firmly against the top of her womb, massaging it gently, while my free hand stroked between her thighs and coated my fingers in her dripping arousal.
I smirked at the sticky fluid now glistening on my hand.
She must’ve gotten this excited because it felt that good. I wonder what would happen if I actually put it in.
It seemed like she’d cum her brains out, just like the saying.
“Serin, did the massage feel good?”
“Huh?”
“It’s so ridiculously wet down here that I think just rubbing the tip a little would slide all the way in.”
“Haaah… hngh, S-Sihyun, stop teasing me…”
The relentless stimulation seemed to be draining her patience; her deep breaths were growing faster and faster. Her thighs rubbed together restlessly, as if her pussy was itching.
A massive amount of nectar flowed from her folds. I teased her by nudging just the tip between her lips, sliding it up and down to tickle her with my glans.
“Ahh♥ W-wait…! If you keep doing that, I’ll get too sensitive.”
“This is part of the massage too, miss~ Rubbing it gently like this helps with blood circulation, you know.”
“What kind of massage is thaaat…♥ Khk.”
Schlop. To calm the struggling Serin, I drove myself deep inside her. The moment I bottomed out, her reaction was immediate. Her mouth fell open, gasping, then snapped shut, only to open again in a repeating cycle.
“Oohhh… W-wait. Th-this feels way too different from usual… ngh♥”
“That’s because I’m pressing right here.”
While keeping pressure on her womb, I used my other fingers to rub her swollen clit, now plump like a little bean.
The response was unmistakable. When I pressed it lightly with my thumb and stroked it like a joystick, her inner walls convulsed and clamped down hard.
Serin really was the perfect toy to play with. I savored the way her tight pussy flesh gripped me, and when I tried to pull out slowly, her legs wrapped around my waist to stop me.
“Did you think this would keep me from moving?”
“What the… ngh! A-at least go a little slower, okay!?”
With my waist locked in place, my range of motion narrowed. But the narrower it became, the more I could slowly, deliberately grind against her deepest spots.
Press. Press. I knocked against her twitching cervical entrance with my glans, gently scraping the sensitive ridges along her inner walls.
“Hyaa!?”
That distinctly bumpy, different texture. I attacked what was known as the G-spot with a powerful thrust.
“Ah, aah…! Haaang. If you keep tormenting me like this… ah!”
Shiii. She came. A fountain-like spray erupted from between her legs, soaking the sheets along with her hot moans. Serin writhed in ecstasy, her entire body shaking.
Female pleasure was stronger than male pleasure, but it didn’t last as long.
Once her trembling eased, I kept myself buried inside her and started moving my hips again.
Creak. Creak… Using the rhythmic squeak of the dormitory bed springs as background music, I set a new pace.
“No, not again!! My womb’s dropping… If you cum inside now I’ll get pregnant. It’ll be a definite pregnancy ngh…♥”
“Looks like the womb massage is finally showing results. Serin, your womb’s come all the way down to kiss my cock.”
“Haaahk!?”
Whether she wanted to get pregnant or not, her cervix had descended on its own, as if personally greeting my shaft.
It seemed Serin could feel it too. From a while ago she had been squeezing me rhythmically, as if trying to milk my cum out as fast as possible.
Then I’ll have to give it to her properly!
As she wished, I thrust upward with force, driving myself as deep as I could go.
After building up for a long moment, I felt the boiling semen surge from the base and released it all inside her.
“Th-the cum is coming… Ah, this is it. I’m really going to get pregnant…”
Exhausted from the thorough massage and the intense session, I collapsed beside Serin and lazily kneaded her breasts.
“You’ll take responsibility if I get pregnant, right?”
“…Yes! Of course I will!”
“Before that, at least use contraception.”
“Ah…”
I didn’t know what she’d been hoping for, but the pure, innocent way Serin stared at me was unbearably cute.
After inserting the contraceptive into her, she lay down beside me again.
“Haa, that was amazing. Is this what life is supposed to be?”
“What’s this, saint mode activated? Your face is completely melted.”
“All women are like this. After a big orgasm your whole body goes limp and you just want to fall asleep right there.”
“No way. If you’re going to sleep, go back to your own room. This bed’s too small for both of us.”
The dormitory bed really wasn’t made for two. Even now, half my body was wedged between the mattress and the wall.
While I rested, gently fondling Serin’s soft breasts, she seemed to have something to say. She stroked my head and rested her hand on the back of my neck.
The warm sound of her heartbeat through her soft skin brought me a strange sense of peace.
“I’m sorry we won’t be able to see each other for a while.”
“Are you going to work part-time?”
“Yeah. An older friend originally asked me to come help, but now I have a goal I need to chase, so I have to go.”
“A goal, huh.”
She simply smiled and gave me a small, gentle kiss on my forehead.
“I’ll show you later. Until then, you can’t meet other girls, okay?”
“Hmm~ I’ll think about it.”
“You… seriously.”
“Then earn your money quickly and come back. I’ll always be waiting.”
Of course, if you’re too late, another woman might snatch me away.
From the recent reactions, it looked like Jaehee would accept if I asked her for that kind of service. If Serin was gone, Jaehee was the only one left.
I closed my eyes and pulled Serin into a tender embrace.
Should I sleep a little?
Holding each other like this, sleep came easily. It felt like I could safely set off on the journey.

— The Childhood Friend Who Promised Marriage Ten Years Ago Has Returned
Should I start with the one that interests me most?
There was one world that had intrigued me the most but which I had kept avoiding.
Every time I considered choosing it, a strange unease settled over me. It was finally time to select Childhood Friend of the Petrification Hero.
Since I’m the childhood friend, I probably won’t get petrified, right? Still kinda scary, though.
Honestly, I had no idea what a “petrification hero” even was. Maybe a hero who turned things to stone, or perhaps something related to fossils. Who knew.
But the important thing was gathering traits by traveling through these different worlds.
I need to grow stronger. More growth means more opportunities.
After returning from the yakuza world, I had learned just how terrifying weakness could be.
Just like today, when I was beaten senseless purely because of a difference in power. I had to build strength to prevent that from happening again.
In this world, you will receive the Blessing of Mana. Your mana stat will increase significantly.
Due to the Unfortunate Life trait, Luck is fixed at Lowest.
Strength — Lower-Middle
Agility — Lower-Middle
Luck — Upper-Middle → Lowest
Intelligence — Middle
Mana — Lowest → High
“This place…”
When I looked up, a clear blue sky filled my vision. Not a single cloud marred the peaceful expanse.
Around me, grass grown lush and thick under warm sunlight tickled my feet, while a large tree offered a cool, inviting shade.
“Sihyun.”
“Huh? Yeah…”
Memories flooded into my mind. This was a quiet rural village, and the girl standing before me was apparently my childhood friend.
The girl with long, flowing brown hair took my hand and pressed it gently against her chest.
“I heard you’re leaving this place to attend the magic academy.”
“That’s right…?”
In the empire, whether commoner or noble, talented mages were nurtured at the newly established magic academy. I had been chosen as one of those talents and was now leaving this countryside behind.
“I wanted to say this before the chance disappears. I like you.”
The sudden confession caught me off guard for a moment, but the sincerity was obvious in her flushed cheeks and the way her large eyes trembled. I couldn’t possibly reject such pure, genuine feelings.
“I like you too, Serin.”
I stepped forward, gave her a light kiss on the lips, and pulled back.
Watching two young people share such innocent love, I felt myself slipping into that same pure, childlike mindset.
“If you truly like me… then someday, when you’ve grown into a wonderful person, come find me. I’ll be waiting at the academy.”
“Yes! I’ll become someone amazing and come for you, Sihyun!”
That night, I left the rural village and headed for the academy in the capital.
Luckily, there were many students from commoner backgrounds like me, so I adapted to life there quickly.
Or rather, I had no choice but to adapt. I was a talented child blessed by mana, after all.
I followed the professors’ lessons, created new spells, and carved the fundamentals of mana into my mind. As my knowledge grew, I steadily took on the bearing of a true mage.
All while waiting for the girl who might one day come looking for me.
“Hey, Sihyun? What special day is it today?”
“Why are you asking that out of nowhere?”
“The professors have been rushing around since morning. It must mean someone important is visiting!”
“Maybe… but to me they just look exhausted like always.”
And fate found me far sooner than I expected.
In the plaza where every magic academy student had gathered, a woman wearing white armor approached me.
She wasn’t riding a white horse, but her beautiful face, lovely brown hair, and the familiar, comforting scent that reached my nose were unmistakable.
“Just as I promised, I’ve come for you. Let’s go together now.”
At my childhood friend’s sudden touch, my lips were taken by force.
“Oh my…”
And that was right in front of every student and professor.

This is the protagonist’s appearance in the hero world setting. The reason it was uploaded in a gender-swapped state is because male characters just don’t render well…
