Thanks, Doc!

Seong-il and Hana answered Dr. Woo, then checked the information on the first gym of the other shelter he had assigned them.

"See you in a bit, Hana!"

"Yeah! See you later!"

Seong-il and Hana agreed to head back to their respective homes, greet their parents, and meet up again afterward.

'Guess I should head home first...'

Seong-il returned home, where his mother figure, Lisa, greeted him warmly.

"Seong-il's back!"

"Huh? Y-yes..."

"Hehe... Using polite speech already! All grown up as of today, are we? You're making your mom all sentimental..."

"..."

Lisa treated Seong-il with affection and began fussing over him, explaining her own youthful adventures while handing over various supplies.

"Seong-il! You must use the tent Mom gave you whenever you camp out, okay? Hygiene is incredibly important when you're roughing it! Don't forget to clean yourself with the hygiene spray! Got it?"

"Yes... Y-yes, ma'am...."

After awkwardly wrapping up the conversation with Lisa, Seong-il prepared to leave the village with Red.

What stood out was that Red didn't particularly like going into her ball. She preferred sticking close to Seong-il and following him around.

'So this is what they meant by good socialization? We just met, but she already likes me a ridiculous amount just because I'm her trainer...?'

As he walked, Seong-il recalled Dr. Woo's earlier explanation about Pocket Girls.

Recalling Dr. Woo's words, Seong-il stared blankly at Red. Before he knew it, he muttered quietly to himself.

"...Wow, she really does like me a lot."

When Seong-il muttered, Red tilted her head cutely and looked at him. "Ah?"

"I wonder if she likes skinship too...?"

Seong-il carefully watched her reaction as he gently stroked her back.

Far from disliking his touch, Red pressed her body close like a cat and began rubbing against him.

Encouraged, Seong-il grew bolder and started caressing her head, waist, thighs, and even her breasts.

Even though those were incredibly sensitive and stimulating ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠areas, Red didn't resist at all. Instead, she let out soft moans and clung to him even tighter.

'Oh...'

Red slightly spread her legs, approached Seong-il, wrapped both thighs around one of his, and hugged it while gazing up at him. Her eyes looked like those of an innocent child who had suddenly discovered sex and was burning with curiosity.

"Uh... We're right in the middle of the road... Shouldn't we go somewhere else?"

Red simply stared at him blankly, as if she didn't understand what he meant.

"Um... Yeah... Let's head over there. That way..."

Seong-il led Red into a secluded thicket.

In reality it would have been insane, but the thought that this was a game world—one that actively encouraged sexual activity between men and women—gave him courage.

'It's not like anyone's going to judge me for this in an apocalypse where humanity's on the brink of extinction. Might as well.'

With that mindset, Seong-il boldly entered the bushes with Red.

'It's been a year since Miji cheated and we broke up...?'

Seong-il thought of Miji, his first girlfriend from college. She had been fairly attractive, but after only three months she dumped him for a promising hunter candidate and left.

Since then, Seong-il hadn't even had a one-night stand, let alone a proper relationship. So the sudden possibility of having sex with such a beautiful woman sent an overwhelming surge of excitement through him.

"Gulp..."

Swallowing dryly, Seong-il leaned Red against a tree, looked into her eyes, and mustered the courage to kiss her.

Red, who had no idea what a kiss was, panicked when Seong-il pressed his lips to hers and pushed his tongue inside.

But as he kept kissing her passionately, she began clumsily copying him and gradually grew excited too.

"Mmm... Mwah..."

After quite some time kissing, Red's face was flushed pink. Seong-il, now extremely aroused, stopped caring if anyone might see. He pulled off her top and began roughly sucking on her voluptuous breasts.

"Sluuurp... Shlurp..."

Seong-il roughly kneaded one of Red's enormous breasts that wouldn't even fit in one hand while sucking hard on the other.

Red seemed to enjoy the way he worked her chest; she wrapped both hands around the back of his head and began letting out soft moans.

"Hah... Hngh... Hngh..."

When Red started moaning in excitement, Seong-il grew bolder. He yanked down her pants without hesitation.

"Sluuurp... Shlurp..."

Once she was completely naked, Seong-il buried his face between her legs—where red pubic hair the same color as her hair grew—and began aggressively licking and sucking her pussy.

"Ah... Aah... Aang...!"

Red twisted her body, overwhelmed by the first pleasure she'd ever felt. Her clumsy movements filled Seong-il with a sense of conquest. Filled with confidence, he licked her folds and clit even more fiercely.

"Hah... Hngh...!"

The stimulation must have been too intense; Red suddenly trembled all over, climaxed, and squirted on Seong-il's face.

Hit directly by her juices that carried a sour yet sweet pheromone scent, Seong-il could no longer hold back. He pulled down his pants, turned her to face the tree, and began thrusting into her from behind in a rough doggystyle.

"Aang... Aaang... Aang...!"

Virgin blood trickled down Red's thighs. The obscene sight drove Seong-il wild. He surrendered to pure instinct and began slamming his hips violently.

Between his extreme arousal and how long it had been since he'd last had sex, Seong-il felt an intense urge to cum not long after starting. He began ejaculating deep inside Red.

"Haaah..."

The sensation of Seong-il's semen spraying into her womb seemed incredibly stimulating for Red too; she trembled and cried out in pleasure.

"How does it feel? Did you like it...?"

When Seong-il asked, Red didn't answer with words. Instead she looked at him, gave a bright smile, and buried her face in his chest.

Her utterly pure reaction made Seong-il feel both deep affection and a fresh surge of desire to have sex with her again.

Red stared curiously at Seong-il's cock, then timidly reached out and began touching it.

"Ugh..."

Her touch was incredibly clumsy, but that very clumsiness sent a thrilling excitement through him. Seong-il decided to teach her how to give a handjob.

"Red, can you hold it gently? It hurts if you squeeze too hard."

"Hurts...?"

"Yeah. So just hold it lightly."

Red nodded at his words and gently stroked his cock as if holding an egg.

"Up and down... Yeah... Just like that."

Feeling her soft hand, Seong-il suddenly craved the warmth of her mouth.

"Red. Kneel down for me."

He took off his coat, laid it on the ground so her knees wouldn't get hurt, and had her kneel.

"Red, can you open your mouth?"

She made an expression that said she understood and opened wide. Seong-il carefully slid his cock into her mouth and gave her a command.

"Try sucking on it."

"Mmm...? Mmmph..."

Obscene wet sounds accompanied Red's clumsy blowjob.

"Ah! That hurts... Red, watch your teeth."

Red looked up at his face with a slightly apologetic expression, then smiled brightly and began carefully sucking him again.

"Suck a little harder."

She carefully avoided scraping him with her teeth and sucked with tight pressure. The intense pleasure nearly melted Seong-il's brain.

How much time had passed? Red kept sucking his cock until the pleasure started to dull slightly and a muscle-sore ache began ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠to set in. He could also see she was getting tired.

Feeling ready to unite with her again, Seong-il stripped off the rest of his clothes, spread them on the grass, looked into Red's eyes, and began thrusting into her in missionary position.

Slowly and gently at first.

Red seemed to love the deep, long strokes. So Seong-il would pull his cock almost all the way out before driving it back in. Each time, Red would twist in pleasure and cry out.

But because he lacked experience and it had been so long since he'd slept with a woman, he occasionally slipped out awkwardly mid-thrust.

Yet every time that happened, the disappointed look on Red's face gave Seong-il superhuman focus. Gradually the sex became more natural, and their lovemaking grew more passionate.

He sucked on her plump pink nipples, sometimes kissed her and toyed with her tongue, and when her moans grew deeper, Seong-il came once more.

"Haa... Haa..."

After ejaculating, Seong-il lay down beside Red and gently held her in his arms.

Just as he was savoring that first moment of intimacy and satisfaction...

"Huh? Seong-il? What are you doing here?"

A familiar girl's voice reached his ears.

"Hah... Hana?"

Seong-il was incredibly flustered and embarrassed. He couldn't meet her eyes, instead keeping his gaze on the ground and peeking up at her.

'She's going to think I'm some sex-crazed scumbag...'

But contrary to his expectations, Hana pushed through the bushes, came closer to where he and Red were, glanced at their naked bodies, blushed deeply, and spoke.

"What the... You two were already bonding? It's barely been two hours since you met, and you're already in the middle of it? Seong-il, you're really aggressive! And doing it in the bushes, no less!!"

Even as she said that, Hana couldn't seem to tear her eyes away from Seong-il's cock.

'Hmm? Her reaction... If I play my cards right, I might be able to fuck her too...?'

In the world Seong-il came from, his current state would have made him look like a perverted exhibitionist. But this was an apocalyptic world on the verge of total human extinction. It was a place where wild humans of either gender were kidnapped to preserve the species—men milked for sperm to increase genetic diversity, women impregnated. Naturally, society was educated to approach sex with an extremely open mind.

'I was judging this place by my old world's standards. Our world is falling apart too, but at least the population is still stable, so sexually it's nowhere near as open as here.'

"Ah... Yeah. I figured this was the best way to get close. Wanna join us, Hana?"

At his words, Hana's face turned so red it looked like it might explode. She answered in a trembling voice.

"Eh...? N-no. You're in the middle of bonding with Red... It'd be rude to butt in... L-later. Let's have sex separately sometime."

'Jackpot! She just casually agreed to have sex with me later. Hell yes!'

As if sensing his thoughts, Red bit his neck with a sulky "Ang!"

"Ow! Red, that hurts!!"

Red huffed and turned away with a clearly upset expression.

"Haha. Seong-il~ No matter what, if you say something like that right in front of your bonding partner, of course Red will feel hurt. Hehe!"

Seong-il had momentarily forgotten about Red's feelings in his excitement over the possibility of fucking Hana. He smiled awkwardly and tried to soothe her.

"Sorry, Red~ I won't do that again. Don't be mad. I'll do something nice for you later."

"Something nice...? I like nice things..."

Red smiled brightly and nodded.

After coaxing the reluctant Red back into her ball, Seong-il headed to the gym with Hana.

"Hana. How's Black? Have you bonded with him yet?"

Hana looked flustered as she answered.

"Eh...? Ah... Not yet. Once we get a bit closer... I'll... I'll think about it then."

'Hmm...? She's getting pretty shy. Does that mean Hana hasn't had much sexual experience...?'

In a world where rich sexual experience was the norm, seeing Hana act so embarrassed made Seong-il curious.

'Oh... Now that I think about it, Dr. Woo is Hana's uncle, and the only people in the shelter without blood ties are the protagonist's family who recently moved here, right?'

'In an era where every single human life is precious, they strictly suppress incest to produce healthy offspring. So it's natural she'd have less experience. She didn't even have a partner until now... I'll have to help her out soon!'

With those lewd ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠thoughts in mind, Seong-il set off with Hana through the crumbling concrete jungle toward Shelter B-02.

'A world full of old concrete skyscrapers and wildly overgrown thickets...'

After several difficult days of pushing through the brush with Hana on their way to the next shelter, Black, who was carrying Hana's luggage, suddenly let out a sharp warning.

"Ugh... E-enemy..."

Though Black's speech was clumsy, the moment Seong-il heard him he immediately went on guard and summoned Red.

"...What is it?"

As the party raised their defenses, rocks began flying toward them. Hana yelped in surprise and shouted at Black.

"Black! Barrier!"

"Yes...!"

Interestingly, at Hana's command Black spread his hands and instantly created a powerful telekinetic barrier.

'Whoa... If I could have that level of psychic power, I'd be treated like a king back in my world.'

Seong-il watched Black's defense in admiration. But the barrage of rocks didn't stop, and Black began to struggle.

Then a faint silhouette appeared.

"Red! Fire a flame blast at the person over there!"

"Okay!"

The moment Red heard Seong-il's order, she launched a powerful flame blast at the indicated spot.

Whether the enemy took a direct hit from her wide-range attack or simply decided to retreat from the threat, the rock barrage finally stopped.

'Wow... These psychics' powers are no joke. Is this what pro hunters are like?'

Just as he was thinking that, someone from the direction of the attack shouted at the ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠party.

"Is that all you've got? Pathetic skills."

A sharp-featured young man with yellow hair had suddenly appeared. He mocked them.

"Who the hell are you?! Did you attack us? Why?!"

Hana spoke warily as she stared at him. The yellow-haired man answered her with a brazen expression.

"You brats are the rookies who just got your partners from Dr. Woo at Shelter A-01 and were sent out on an external mission, right?"

'Look at this arrogant little shit...'

His completely rude tone made Seong-il openly show his displeasure as he replied.

"Then who the hell are you? You don't seem to be from our shelter. And why did you attack us?"

Instead of answering, the guy summoned his partner from a ball.

"Huh?!"

It was Blue, the one who had remained after Seong-il and Hana each chose their partners. Seong-il immediately realized this guy was his second rival.

"You don't need to know who I am. What matters is that your pathetic skills are wasting your partners' potential. In that sense, hand your partners over to me so I can draw out their true power properly."

'...Crazy bastard. Like hell I'd give someone like Red to you.'

Seong-il and Hana were dumbfounded by the provocation. Instead of answering, they immediately prepared for battle.
