Chillin' on an Uninhabited Island in Another World

The room assignments were decided: immediately up the stairs on the right were three rooms—starting from the far end, they belonged to Shouko, myself, and Minori. On the left side, starting from the back, were Chiyu, Shion, and two vacant rooms.

I didn't have any particular preference for my room's location, so it was fine by me, though I wasn't really given a choice in the matter.

And now, I sat upright alone on my bed inside the room, illuminated by the flickering light of a candle.

Chiyu had said she would come by later. She liked her jokes, but she wasn't the type to deceive me. She would definitely come.

However, in this situation without a clock, I had no way of accurately measuring how much time had passed. I felt like I had been waiting for over an hour, yet if someone told me it had only been ten minutes, I’d probably believe them.

My expectations were swelling; I was restless.

Eventually, the door to the room opened without a knock. My childhood friend appeared, dressed in her pajamas.

In her hand was the candlestick and candle I had distributed to everyone. After closing the door, she blew out her own candle and placed it on my desk.

"The two in the rooms next door might already be asleep. It would be a pity to wake them up with any noise," Chiyu said.

"I-I see," I replied with a stiff nod.

As I agreed, a sense of guilt—a sort of illicit thrill—rushed up my spine at the thought of doing something while Shouko and Minori were right there in the adjacent rooms.

Chiyu sat down beside me as if it were the most natural thing in the world.

"Candles are amazing. With this, I can see your face even inside at night."

Chiyu spoke while resting her hand against my cheek. I knew instantly she was remembering how we had missed the mark during our kisses several times last night.

"With this, we won't fail."

"It’s fine even if we do. We'll just keep trying until we succeed."

I locked eyes with her blue orbs, which looked as though they had trapped the very sky within them.

We drew closer, our lips touching. That simple act alone brought a tremendous sense of happiness; our movements gradually grew more intense, and our bodies naturally pressed tighter together.

Chiyu’s lips clung to mine at every moment, and each time they pulled away, they let out a soft "chu... chu..." wet sound.

Amidst the deepening kisses, a squelching "picha... pichu..." sound began to mix in.

Finally, without either of us prompting it, our tongues became entangled. We let out ragged breaths—"fuu... nnh..."—as if hungrily devouring the insides of each other's mouths.

The slender body of the Chiyu I was embracing, the sensation of her huge breasts pressing even harder against me, her body heat, and her scent—every element radiated by my childhood friend was precious and drove my excitement higher.

Even though we had only just exchanged kisses, "it" was asserting itself with enough force to potentially punch through my pants.

"Chiyu..."

"Mm. So-kun, get on the bed."

"A-Ah, okay."

Moving from my seated position, I laid my whole body onto the bed. Chiyu followed, but then she reached for the hem of her pajamas and slowly pulled them up.

"Ch-Chiyu, you don't mean...!"

Gulping, I stared at Chiyu’s chest as if trying to burn holes through her.

Her navel was exposed, the full view of her slender stomach was revealed, and then—boing.

I didn't know how to describe it. They were round, white, and beautiful like the moon; they jiggled like swaying pudding, and just by looking, you could tell they were as soft as freshly pounded mochi.

And there were two of them. But the difference from all those things was the cute protrusions at the tips.

"So-kun, you're looking too much," Chiyu said, sounding embarrassed for once.

But I couldn't tear my eyes away. It seemed Chiyu had come to my room without wearing a bra.

"Ch-Chiyu, that's..."

"Mm. Your current childhood friend... is okay with being touched."

I gently reached out both hands and, hesitatingly, touched her breasts. The first thing I felt was a silk-like texture, followed by a softness so deep my fingers sank right in.

Smooth, fluffy, springy, and heavy.

Even if I mobilized every word in existence to describe skin texture and softness, I wouldn't be able to express even ten percent of the emotion I felt.

I finally understood the feelings of people who stare at a single painting in a museum for hours. The moving sensation crashing against my heart was limitless, and I was overcome by the urge to keep admiring them for as long as I was permitted.

"Nnh... So-kun... you like breasts too much."

"Sorry, Chiyu-sama."

"...Sama?"

"No, I mean, someone who possesses such magnificent things... calling them without a title is just, well..."

Shouldn't they be worshipped?

"I'm sorry they are such charming breasts that they broke So-kun's character."

"I want to touch them forever."

"That's fine. But... what about here?"

As if in return, Chiyu stroked my crotch.

"...I-It's not fine. Please, today as well."

Though I felt a lingering regret, I pulled my hands away from Chiyu’s breasts.

"No need to look disappointed. So-kun, take them off."

"A-Ah."

When I pulled down my bottoms, "it," which had been maintaining a combat-ready state for a while now, was pointing toward the heavens, swollen to its limit.

Chiyu stared at it intently. Since I had been staring at her breasts, I felt embarrassed but couldn't blame her.

"I feel like it's bigger than yesterday."

"M-Maybe... well, it's because I can see you clearly, Chiyu."

"...I'm happy. But So-kun."

"What is it?"

"Are you getting big because of me? Or because of my breasts?"

"Aren't they both 'Chiyu'?" I said with a brilliant smile.

"You dodged the question," she replied, her words a little sharp.

Shifting from her kneeling position, she collapsed her legs to the sides and patted her thighs.

"So-kun, put your butt here."

...In other words, I was to spread my legs and, while lying on my back, rest my rear on Chiyu’s thighs.

"T-That means, Chiyu, surely...!"

Realizing what she was about to do, my eyes went wide.

"If you shout, the other two will wake up."

I hurriedly covered my mouth.

Then, without hesitating over the somewhat unsightly posture, I lifted my hips while lying face up. Chiyu didn't laugh; she quietly slid her body in and received my lower half.

"So-kun, you're a peerless breast-lover."

"Ugh."

"But I heard from Shion. Apparently, I am the cause of that fetish of yours."

"Not the 'cause'... more like the 'trigger,' I guess."

There was no point in denying it.

"Hehe. Your beloved childhood ◈ Nоvеlіgһт ◈ (Continue reading) friend grew huge breasts when she started middle school, so So-kun became a lover of big breasts too, right?"

While I hadn't noticed them in elementary school, her chest had undergone an incredible growth spurt once she entered middle school. And they had grown even larger since then.

Great spheres like melons, possessing terrifying softness and tension, were hanging from my childhood friend. Even though nothing had been done yet, "it" was twitching with anticipation.

"Then, I'll make you like them even more."

Chiyu let the saliva she had gathered in her mouth drip—slorp—into her cleavage. Every time it sank into the depths of her breasts, she kneaded them with her own hands. She repeated this over and over right in front of my eyes.

I thought I was going to go crazy from the anticipation and excitement. My rod was harder than it had ever been in history; it was frightening even to me.

"Mm... it's getting all gooey inside the breasts."

Chiyu pressed my throbbing rod against the valley on the underside of her breasts.

"So-kun, is this your first time 'inserting' into breasts?"

"O-Of course it is."

"Then, your 'breast first' belongs to me, too."

In an instant, it felt as though that part of me alone had entered a hot bath.

But that wasn't all. It was the sensation of being surrounded on all sides by lubricant and being squeezed by something incredibly soft.

"Guh...!!!!!"

My whole body jerked from a pleasure that felt like being struck by lightning. It was such an explosive feeling of goodness that it was a miracle I didn't misfire immediately.

"So-kun, you look like you're feeling good. I see, when you're feeling it, you make that kind of face."

Lifting up, dropping down. Lifting up, dropping down. Squish... boing...! Squish... boing...!

Through the visual impact and the sensation of "it" being rubbed through the slime, my brain was being filled with pleasure-inducing substances. Right now, I was drowning inside the girl known as my childhood friend, Chiyu.

"Nnh... nnh... nnh."

She repeatedly lifted her breasts and swung them down. All of it was simply to follow the fetishes of her childhood friend and fulfill those desires.

My heart grew hot at the affection she showed by doing this for me. Well, parts other than my heart were getting hot too...

"Ah... it twitched. It's coming soon, isn't it, So-kun?"

It seemed that from just that one time yesterday, Chiyu had grasped the omens of my discharge.

"I heard you poured a lot onto Shion's chest."

"...!"

As expected, information was being shared among the girls.

"I'm not particularly angry. But honestly, I'm frustrated."

"F-Frustrated?"

"You came twice in a row for Shion. To be the 'winning heroine' childhood friend, I'm going to make a comeback here."

"No, Chiyu..."

Coming twice for Shion and once here for Chiyu is already quite a lot...

"No problem. According to the manga So-kun was reading, men can come dozens of times a day."

"That's because it's a manga...!"

Just as the specs and work of a "detective" in fiction are puffed up into a sort of stylized beauty, the specs and ejaculate volume of a man's crotch in fiction are massively exaggerated. The readers accept that lie and enjoy the story. You can't take it seriously...!

"Since you came twice for Shion, I'm confident I can make you ejaculate four... five... no, ten times as much."

Am I going to have ten rounds squeezed out of me starting now?! I'll die!

But sadly, I couldn't escape the pleasure my childhood friend was giving me.

"Guh, Ch-Chiyu!"

"Mm. It's okay. At the best timing, let it out however you like."

Chiyu’s movements accelerated.

"When you were in Japan, what did you let it out into? Did you think of me and do it into a tissue...? You don't have to do that anymore. Not into a tissue... you can do it into me."

My childhood friend, who had a direct line to my fetishes, delivered the finishing blow with a whisper specialized for me.

"Let it out, So-kun. Do it all—splurt, splurt, splurt—inside your childhood friend's breasts."

"Gah...!"

My hips arched, and I shook uncontrollably.

Along with that, a slushy, magma-like heat was released into Chiyu’s breasts. At the moment of discharge, Chiyu stopped by swinging her breasts down, receiving it all gently.

"Splurt, splurt, splurt... amazing, it's still going. Splurt, splurt, splurt... splurt... It's like you want to get my breasts pregnant. ...Ah, look, So-kun."

Chiyu called out to me while I was dazed, staring blankly at the ceiling with flickering vision.

When I looked, a white, cloudy liquid—different from saliva—was overflowing from her cleavage.

"So-kun, you got so excited by me you're erupting."

My thing should have been completely buried inside Chiyu’s breasts, but due to the sheer force and volume, it seemed to have come spraying out. Chiyu looked satisfied by this.

"...Did it feel good?"

"...Yeah, it was the best. Hey, Chiyu."

"What?"

"Y-Yesterday, you know, Shouko and Shion came in the middle of it, so my turn to make you feel good was put on hold, right? Yet today you made me feel good first again... Let me thank you now."

"So-kun. Of course, I want you to make me feel good too."

"Yeah, I'll do my best."

"But—"

Chiyu pressed down on her breasts with both hands.

"?!?"

"It's fine after I've squeezed out five times as much as Shion."

The lubricant—a mixture of my white liquid, Chiyu’s saliva, and sweat—turned the space between her breasts into an even more slushy and gooey realm. Being pressured by that, my thing regained its strength as a rod.

"H-Hey, Chiyu. Listen to me calmly. Those materials you read are fiction; real men can't produce that much."

"...I understand."

"O-Oh, good, you understand..."

"For now, I'll have you come two more times like this. That way it'll be three to two, and I can save face as the childhood friend."

Two more times starting now...?! Even back in middle school when I first learned how to comfort myself, I never did it five times in a day.

"And once that's done, I'll cast Basic Heal. Your 'So-kun' will recover too."

"Awa, awawawa..."

I was trembling at my childhood friend's declaration of absolute milking.

The broad-mindedness to permit a harem, the mercy of knowing her childhood friend's desires inside out and making his dreams come true... When you add her competitive streak of not wanting to lose her spot as number one to that, my childhood friend had transformed into a monster like a succubus.

"Of course, if So-kun hates it, I'll stop. If you say, 'Chiyu's breasts are worse than Shion's handjob so forget it, go home,' then I'll go home and cry into my pillow."

Isn't that phrasing a bit unfair...? I steeled my resolve.

"I-I get it. Chiyu... well... I want to do it a lot with you, too."

Chiyu nodded. Her expression didn't change, but I could tell she was happy.

"Leave it to me. Just like in those books you had, you can turn my whole body white."

No, like I said, that's fiction... Wait. If my energy can be restored with Basic Heal, could it actually be possible to reproduce that?

I was a little scared that my brain might break from the pleasure leading up to it.

"Here I go, So-kun."

"Ah, Chiyu, wait a sec—"

Boing...!
