With the volleyball club girl, Mamonaka Miyao, officially joining their ranks, everyone gathered around the table to share information over a spot of tea. Minori diligently took notes on everything Mamonaka provided, likely intending to compile it into their reference materials later.

"So, Ryouka is running the show for all the girls who aren't here?" Shouko nodded in response to Mamonaka's question.

"Yep, exactly. In fact, Urume came over to our side from that exact team."

"Sure did!" Urume chimed in. "Honestly, once the others find out what this place is really like, they're all gonna want to move in."

"I-I mean, yeah... Building a whole house like this? You're amazing, Kuno..." Mamonaka looked at Sousuke with eyes full of pure admiration.

"Speaking of the house, it might actually be a good idea to build one for Suou’s team as part of our next trade." While managing the baths and laundry would still take some effort, securing proper housing would drastically improve their overall quality of life on the island.

"You really are a very kind person, Sousuke-kun," Ms. Luminous remarked, looking genuinely pleased.

"...If Kuno's cool with it, fine," Yumekai interjected. "But I think that way exceeds the value of anything they can give us in return right now. Most people will just take it for granted without a second thought, and if you leave them to their own devices, they're going to start getting cocky."

Chiyu spoke up, fully backing Yumekai's concern. "Mm. I'm not letting anyone exploit So-kun just because they think they're entitled to a free ride. The only thing he should be getting milked for is his seed."

Those who immediately understood the phrase turned bright red, while those who didn't simply tilted their heads in confusion. Deciding it was best to ignore the comment for now, Sousuke kept the conversation moving.

"I don't intend to offer free charity either. If I start doing that, I'll end up having to take care of every single transfer participant until we can all go home."

Once people realize they can access something for free, they quickly grow to view it as a given. Even if it was originally something that required a fair exchange, introducing a cost later down the line only breeds resentment. Unfortunately, the percentage of people who possess the grace to feel grateful and offer something in return is small. If he began helping outsiders out of pure goodwill, a flood of others would inevitably demand the same treatment, trying to use him. Ms. Luminous had suggested a trade format precisely because she understood this reality.

"Then what are you going to do?" Shion asked, looking at him with a trace of anxiety.

"When it comes to Suou and her group, I plan to give them the base upfront on an installment plan."

"An excellent strategy, Master," Roa praised. "Since you have the ability to 'Store' and confiscate the property if their payments lapse, they will have no choice but to keep up their end of the bargain."

Well, a few of them might still try to slack off, but that would be up to Ryouka to handle on her end. For Sousuke, building a house was no trouble at all as long as he had the lumber. In fact, if Suou's team paid for it in raw materials over time, it would actually save his group the labor of gathering everything themselves. It would undoubtedly be tough on the other side since they would have to provide materials for both their regular trade and the installment payments, but he could always consult Minori and Ms. Luminous to adjust the rates to a manageable level.

"Yes, I think that's a fair compromise," Minori agreed. "From a business perspective, it works, and emotionally speaking, it was getting a bit painful to look at our classmates living in a cave while we have all this."

"I know what you mean..." Urume added. "I was lucky enough to join the party, but it's not like we can just take in all my friends. It felt a little bad enjoying such a luxurious life while they were roughing it, so I completely agree with Sousuke's idea."

"Yeah, I felt like I was sneakily jumping ship ahead of everyone else too," Shouko admitted. "If Ryouka-cchi and the others get a house out of this, it definitely takes a weight off my mind."

With Minori, Shouko, and Urume all on board, the plan was solid. In reality, there were still massive differences—such as their bonus-area items, the bath, the laundry system, and the lighting provided by Ms. Luminous's light-and-heat magic. Even so, simply having a proper house would be a massive upgrade for the other group.

From tomorrow onward, Sousuke figured he could offer the same terms to the boys who were surviving alone or in small groups. The more trade partners he established, the more materials would pour in without his team having to lift a finger. Gathering the payments could be a hassle, but riding the phantasmal beasts would cut down travel time significantly. Now that they had located all the girls on the island, the boys were the only ones left to find. Their comfortable, easygoing deserted island life was finally within arm's reach.

"Alright, let's take some free time until dinner. Can someone show Mamonaka around the house?"

"I shall handle that," Roa volunteered, raising her hand.

"Great. Thanks, Roa."

"Leave it to me."

"Thanks, Roa..." Mamonaka paused, glancing at her outfit before finally asking the question she had been holding in. "By the way, I've been wondering this whole time... why the maid outfit?"

"I shall explain everything as we tour the premises."

"U-Uh, okay..."

"Oh, by the way, Myao," Shion called out. "Is there anything specific you'd like to eat for dinner tonight?"

"Huh? Why me?" Mamonaka blinked in confusion.

Sensing Shion's intention, Sousuke explained on her behalf. "Ah, normally our welcome parties are outdoor grilled meat meals, but we already threw one for the teacher and Urume earlier today. Shion's offering to make whatever you want instead."

"Oh, I see! Anything at all?"

"As long as I have the ingredients, I'll make it," Shion smiled.

"Could you... maybe do a katsu-don?" Mamonaka asked, her eyes lighting up with a classic sports-club appetite.

"We don't have any rice right now, so..."

"Oh, right. Obviously, we wouldn't have rice on a deserted island..." Mamonaka's shoulders slumped in disappointment.

"But we have all the other ingredients," Sousuke offered. "Shion could probably make it as a wild boar katsu-ni. How does that sound?"

Mamonaka’s face instantly brightened. "Yes! I'd love to have that!"

"You got it," Shion replied happily, heading off toward the kitchen.

With that, the group dispersed. Minori headed to the library, Roa led Mamonaka away for the house tour, Shouko went outside to see the phantasmal beasts, and Ms. Luminous began checking the rooms to determine the best spots for her lighting magic. Urume dragged a reluctant Yumekai toward the game room, leaving Sousuke alone in the living room to resume his video game.

A moment later, Chiyu slid onto the sofa right next to him.

At first, he kept playing normally, but before long, Chiyu’s small hand began gently stroking his thigh. He tried his best to tolerate the casual skinship, but her hand slowly drifted upward, eventually reaching his crotch.

"...!"

Noticing that his grip on the controller had faltered, Chiyu took it as her cue. She deftly unbuckled his belt, expertly slipped his rod out from his pants, and leaned down—taking him into her mouth with a soft, wet slip.

A sudden wave of intense heat enveloped him, sending a sharp jolt of electricity straight up his spine.

From the kitchen, the distant sounds of Shion preparing dinner echoed into the living room. This was the middle of the house, and anyone could walk through the door at any second. The overwhelming thrill of danger and the forbidden setting instantly fueled his arousal, sending a rush of blood straight to his groin.

The wet, lewd sounds of her sucking and licking made it impossible to focus on the screen. Giving up entirely, Sousuke dropped the controller onto the floor, surrendering his senses to the exquisite pleasure his childhood friend was giving him.

Before long, he reached his absolute limit.

"Chiyu, wait... it's coming..."

"Mgh..." Chiyu hummed around him, suddenly accelerating the movements of her head.

The heavy, fluid friction and the sweeping strokes of her tongue, combined with the sheer tension of the room, pushed his excitement to a crescendo. With a low groan, Sousuke erupted, discharging his white fluid deep into his childhood friend's mouth.

Pulse after pulse, a massive torrent of built-up desire spilled into her small mouth, pulsing with an intensity far greater than anything he had experienced back in Japan. His vision blurred, a ragged sigh escaping his lips as his hips trembled from the soul-draining ecstasy.

"Mgh... nnh, nglh, nglh..."

Chiyu took every drop, swallowing steadily before slowly pulling her lips away from his shaft. She looked up at him and opened her mouth.

"Ahhh..."

Her oral cavity was completely flooded, a thick layer of white pooling over her tongue. Sousuke swallowed hard at the sight. Satisfied with his intense reaction, Chiyu closed her mouth and took her time swallowing the rest of it down.

She looked up at him with a thoroughly smug, triumphant expression.

"Did it feel good?"

"...It felt amazing, but why did you have to do that here?"

"No matter how many heroines join the group, I'm the strongest one."

It wasn't exactly a logical explanation, but her intent was clear. She wanted to firmly reestablish her position in his mind.

"No matter how many companions we gain, Chiyu, I'm never going to cast you aside," he said honestly, pushing past his embarrassment to make sure she understood.

Chiyu’s cheeks flushed a soft pink. "Basic Heal."

"...Hey."

"Next, I'm sitting right between your knees. Don't worry, we used to do this all the time when we were kids."

"Are you sure that's all you're going to do?"

It was true that they had sat like that when they were little, but back then, it had been a completely innocent gesture between close childhood friends. They hadn't shared this kind of relationship.

"That depends entirely on So-kun's So-kun," Chiyu purred.

Settling herself right between his thighs, Chiyu immediately began rubbing her rear against his rod through her underwear.

Faced with such a direct, teasing assault from his beautiful childhood friend, it was physically impossible for him not to react. Feeling his shaft instantly spring back to life and turn rock-hard against her back, Sousuke mentally lamented just how incredibly weak his male instincts were.

"Looks like So-kun's So-kun is rearing to go again."

"............Yeah, I guess it is."

Accepting his defeat, Sousuke reached into his Inventory and itemized a condom right into his hand. Sitting in a position straight out of a classic adult manga, he began his next round with his childhood friend.
