Multiple updates today.

This is episode two.

Under the blue sky, my childhood friend and I were doing something we shouldn't have been.

The sense of transgression only served to fan my arousal.

"Mm..."

Chiiru let her saliva pool in her mouth, dripping it without waste onto the cleft between her breasts.

The softness of her tits alone was a happiness on the verge of bringing me to an unexpected climax, but added to that was a slime that began to act as a lubricant.

Instantly, the pleasure spiked, and I involuntarily tensed up my hips.

If I just passively accepted this sensation, I wouldn't last even a few seconds.

Unmindful of getting herself dirty, she knelt on the ground and continued her service with her upper body naked.

She sandwiched the stick, kneaded my breasts—wait, my cock—and worked them up and down.

With each movement, the texture and pressure inside changed, sending an inexpressible pleasure racing from my lower belly all the way to my brainstem.

"Mmm... mmm, mmm. It's so hard inside me, K-kun."

My childhood friend, who had a perfect grasp of my sexual quirks, was also well-versed in what words made a man happy.

But, those words I just spoke were probably the truth too.

That’s how incredibly potent the [Vitality Boost] effect was.

Still, if there hadn’t been a reason to get excited in the first place, he wouldn’t have gotten this hard.

“Because Chiyu’s breasts are sexy.”

“If it makes you-him happy, I can be as sexy as you want.”

Looking up at him with her gem-like blue eyes, Chiyu said.

And then she looked down at his umbrella sticking out from the cleavage between her breasts.

“Eh? No, Chiyu, surely you don’t...”

“Boys like this kind of thing.”

Without waiting, she pressed her lips to the umbrella—kissed it lightly with a chuu sound.

“Guh...!”

And this time, she opened her small mouth as wide as it could go—.

“At your-his size now, you can do this. Mmm... mmp.”

She took the tip of the stick into her mouth.

Instantly, accompanied by a wet sensation, the tip was enveloped in something warm.

“—!?”

An indescribable pleasure made my lower back jerk.

It wasn't a place I was supposed to be allowed in, yet it felt as if it existed specifically to accept me.

The juxtaposition of transgression and pleasure was staggering; the depths behind my eyes began to buzz with static.

"Chup... lelo... slurp... glup... mmmph... glup... glupp."

Sei probably did it on purpose, exaggerating the sound of the liquid as she fully commenced her oral service.

My shaft was enveloped in her breast, while my tip was licked by her.

I don't know if that's the right way to describe it, but what a sense of luxury.

Without missing a second, Sei continued to serve with unwavering devotion.

An overwhelming, absolute love that demanded nothing more than my ultimate pleasure.

It wasn't just the act itself; I could feel the depth of her childhood friend's heart.

All of it converted into arousal as milky pre-cum rapidly churned and surged in anticipation of release.

There was no way I could last this long.

"Sei... it's coming...!"

「Juppu... juppu... jubbo, jurruru...... Mm, ra-shi-te. This way, swallowing it all internally...... vyurru-vyurru, all of it, wa-ta-ni-ra-hi-te」

As her service intensified, her movements became a frantic quest to milk every last drop of semen from him, bringing on his limit almost instantly.

“Guh...!”

I pressed hard into my lower back and shot my milky-white fluid, surrendering entirely to the pull of desire.

「Mnn...!? Mm, mm, mm, mm」

With each pulse of my cock, Chiyu responded with a small reaction.

The number of pulses was far beyond normal, and the pleasure accompanying the ejaculation felt two or three times more intense than usual.

That meant I had released a massive amount, yet without opening her mouth even once, she took every last drop with her lips until the very end.

More than that, as if demanding to squeeze out even the final droplet, she licked the tip with the tip of her tongue—chiro chiro—and my cock twitched in response, until the remaining few drops were extracted... taro taro (glisten/thickly).

Despite experiencing such pleasure, all I had done was stand there.

Thanks to my childhood friend’s dedication, I had enjoyed the ultimate experience of having my essence wrung out on auto-pilot.

Eventually, after expelling everything...

She slowly pulled the shaft from her mouth and opened it toward me.

"Ughh..."

Inside her mouth, a milky white liquid mixed with her saliva was brimming to the edge, ready to spill out at any moment.

It was visibly apparent that I had put out so much, and that she had received every last drop without wasting a bit, which triggered even more excitement.

Sena kept her mouth closed as it was, and then—she swallowed, a loud gulp audible in her throat.

"Wa- Wait, Sena!?"

While it was indeed a man's dream, he knew full well that what he was drinking didn't taste good at all.

I told him he didn't have to force himself, but she stared fixedly at his face and, slowly, drank until the very last drop was gone.

Given the volume, it took several swallows to swallow it down, requiring a full minute or two to finish it all off.

Even so, once he had drunk it all, Sena opened her mouth again toward him.

There was nothing left inside anymore; everything had been absorbed into his stomach.

"Koh- koh... I drank it all... Aren't you happy?"

Seeing her anxious expression, he panicked.

"N- No, honestly, I'm incredibly happy and aroused... but it probably tasted awful, didn't it?"

The rod did not even go through the process of losing its erection for a moment; it remained hard throughout.

It wasn't just the magical effect; it was due to Sena's actions. "Hm.

Absolutely fucking disgusting."

"T-That's how it is..."

"But... if it makes Soukun happy, I'll do anything."

"Chiyu......!"

At her words, my member twitched in anticipation.

My childhood friend didn't miss that reaction.

"That's good. You seem happy too. Want me to sandwich it again? Or should I just try your mouth?"

As if it were the most natural thing in the world, Chiyu reached for my manhood and asked with a slick, rhythmic rubbing sound.

I'd had her handle it by hand the first night we met, but today was only our fourth day of island survival.

And yet, what an adaptation speed. What a growth rate.

Despite being inexperienced, my childhood friend was acquiring lewdness in just a few days that could put any perverted demon to shame.

"I'll devote myself entirely to you, Soukun. So, become my captor."

"Captor?

That's not—"
"You already have..."

"—!"

To my words, Chiyu made a surprised face.

Then, clearly and happily, she smiled.

It was the pure, innocent smile of our childhood.

"I'm happy. But if that's the case, I'll make you fall even deeper."

But in an instant, her expression shifted into something lewd.

Sena stick out her tongue and licked its glistening tip with a flickering motion.

"Choose, Sou-kun. What do you want?"

"……Then, once more, with the chest…"

"……Boobs are just too perfect."

Though she remained expressionless, the fact that she was holding it in came through clearly.

"Sorry about that..."

"Nope. It's all my fault. Sorry for having breasts big enough to twist my childhood friend's kinks."

Apparently, she was joking.

"...Yeah, it's Sena's fault."

When I laughed, she smiled back.

"Mm. I'll take responsibility properly. And I cast the enhancement magic on you too."

Regarding that matter, though.

"...Hey, there's no sign of this wearing off at all. How long will it stay big?"

Sena looked away.

"...Are there any downsides to being big?"

"You don't know either...!"

"If I keep giving more, it should settle down... let's hope so," he said. A optimistic outlook...!

"Hey, hey..."

"Should I stop then?"

That was a bit unfair question to ask.

"...No, please.

Just do it."

"Roger that."

After that, I got squeezed about three more times by Chiyu in quick succession, but there was no sign of the [Vitality Enhancement] effect wearing off.

"I can't take this down on my own. I need everyone's help."

"Don't sound like a boss battle alert..."

It would be a lie if I said I wasn't happy about it growing larger, but the problem was that because my vitality remained enhanced, even the slightest stimulation threw me into combat mode.

"Harem usage in times like these."

"You didn't anticipate this kind of situation, did you?"

I figure it'll wear off eventually, but... what am I gonna do from this afternoon on?

Multiple updates today, this is the second one.

I'm doing something naughty with my childhood friend under the blue sky.

This sense of sin only added to my excitement. "Mm..."

Chiyu was storing saliva in her mouth and dripping it into the valley between her breasts.

Even just the softness of her breasts was enough to make me feel like I might explode with happiness, but now the added slickness worked as a lubricant.

Instantly, pleasure shot up, and I couldn't help but put more strength into my hips.

If I just enjoyed this pleasure honestly, I wouldn't last even a few seconds.

She didn't mind getting dirty and knelt on the ground, continuing to serve me with her upper body naked.

She squeezed my cock between her breasts, kneading them and moving up and down.

Each time, the sensation and pressure inside changed, and an indescribable pleasure shot up from my lower abdomen to my brain.

"Mm... Mm, Mm. Soun-kun, you're getting hard inside me."

My childhood friend, who perfectly understands my sexual preferences, also knows exactly what words to use to please a man.

But, those words are probably her true feelings too.

After all, the effect of "Erectile Enhancement" was that powerful.

Still, if there hadn't been any factors to excite her in the first place, she wouldn't have gotten this far. "Thousand Heals' breasts are erotic."

"If Sou-kun is happy, I'll be as erotic as you want."

She said, looking up at me with eyes as blue as jewels.

Then she looked down at the umbrella sticking out from between her breasts.

"Eh, no, Thousand Heals, you wouldn't...?"

"Boys like this sort of thing."

And then, she kissed the umbrella -- "Chu." "Guh...!"

Then she opened her small mouth as wide as she could --.

"Given how big Sou-kun is now, I can do this. Nn... mm." She put the tip of the shaft in her mouth.

Instantly, the tip was enveloped in something warm, along with a slippery feeling. "――――!? "

My hips jerked from an indescribable pleasure.

Even though it wasn’t supposed to be a place for it, it felt like it was meant to accept it.

The mixture of guilt and pleasure was overwhelming, and my eyes started to blur.

“Chu, rero… Juru… Jupu… Nmuh… Jupu… Jupu…”

Thousand Healing probably did it on purpose, making exaggerated slurping sounds as she began her oral service in earnest.

The shaft was enveloped in her breasts, and the glans was being licked.

I didn’t know if this was the right way to say it, but what a luxurious feeling.

Without taking a single second’s break, Thousand Healing continued her devoted service.

If I could experience the greatest pleasure, that was all that mattered to her, an overwhelming amount of love.

Not just the act itself, but even the depths of her childhood friend’s heart were transmitted to me.

All of it was converted into excitement, and the white, viscous fluid waiting for release rapidly increased.

There was no way this could last long. “Thousand Healing… soon…!”

「jup... jup... jubo, jyururu...! Nn, l-let me... I’ll take it all inside my mouth... biyubiyu, everything, take it all...」

Her service became more intense, and her movements aimed at milking out my cum immediately pushed me to the limit. 「Guh...!」

I thrust my hips forcefully and released my white fluid as my desire dictated.

「Nnh...!? Nn, nn, nn, nn」

Every time my member pulsed, Senyuu reacted slightly.

The number of times was not comparable to usual, and the pleasure accompanying the ejaculation was felt to be more than twice as intense as usual.

In other words, it meant that a large amount had come out, but she did not let go of what she had in her mouth and continued to take it all in with her mouth until the end.

In fact, she even lapped at the tip with her tongue as if urging me to release the last drop, and my member twitched in response as the remaining few drops were slowly milked out.

Despite having experienced such pleasure, all I did was stand there.

Thanks to my childhood friend’s dedication, I had the best experience of being milked automatically. Eventually, after I had released everything.

She slowly pulled her mouth off my member and opened it toward me. 「Nnhaa...」

Inside her mouth was a generous amount of white fluid mixed with her saliva, and it was about to spill out.

I could see that she had taken everything I gave her, and it only made me more excited.

Senyuu closed her mouth and then, what the hell, she started to swallow. "Nn, Senyuu...!?"

It was certainly a man's dream, but it was obvious that it wasn't something delicious to drink.

I had told her not to force herself, but she looked at me the whole time and slowly drank it all.

Because of the amount, she swallowed it in several gulps, and it took a minute or two to finish.

Even so, when she had finished drinking it all, Senyuu opened her mouth again, facing me.

There was nothing left inside. It had all gone into her stomach.

"Cough, cough. I drank it all. ...Isn't that great?"

Seeing her worried face, I panicked.

"N-no, honestly, I'm really happy and excited, but... It must have tasted awful."

The shaft didn't even go soft for a moment; it just stayed hard the whole time.

Not just the magic effect, but also her actions. "Mm. Absolutely disgusting." "Y-yeah..."

「But... if it makes you happy, Sō-kun, I'll do anything.」 「Chiyu...」

The stick trembled nervously at her words.

My childhood friend didn’t miss it.

“Good, you look happy too. Want me to do it again? Or should I try something else with my mouth?”

She casually reached out for me, rubbing and asking.

She had done it for me the first night, but it was only the fourth day of our life on the desert island.

And yet, what an incredible adaptation speed, what a remarkable growth rate.

My inexperienced childhood friend was already wearing a lewdness that would shame even a succubus in just a few days.

“I’ll devote myself to you with everything I have. So, become my captive.” A captive? “I already am...” “――――!”

After hearing my words, Chiyu’s face showed surprise.

Then, she clearly smiled happily.

That smile was as innocent as it was when we were children.

「I'm glad. But if that's the case, I'll make you even more captivated.」

But just a moment later, it turned lewd.

She stuck out her tongue and licked the tip seductively.

"Choose, Sōkun. What do you want me to do?"

"…Then, one more time, with my chest…" "…I love your boobs too much."

Even though she was expressionless, I could tell she was pulling back. "Sorry…"

"No, it's all my fault. For making your childhood friend's sexual preferences go awry with my huge breasts, I'm sorry." It seemed like she was joking.

"…Yeah, it's all your fault, Chiayu." When I smiled, she smiled too.

"Hmm. I'll take my share of the secret. I cast the enhancement spell too." Speaking of which.

"…Hey, this doesn't seem like it's going to wear off anytime soon. How long are you going to stay this big?" Chiayu looked away.

"…Is there something wrong with being big?"

"You don't even know…!"

「The more you produce, the better it’ll be, right?」 That’s wishful thinking…! 「Hey, hey…」 「So, should I stop?」 That’s a tricky question. 「…No, please don’t.」 「Understood.」

After that, I was squeezed several more times by Senyuu in a short period, but there was no sign that the effects of the ‘Ejaculation Enhancement’ would wear off.

“This is something I can’t handle alone. I need everyone’s help.”

“Don’t say it like a strong enemy appeared…”

I wouldn’t lie if I said I wasn’t happy about it growing, but since my energy was still enhanced, it was a problem that I would be put into a combat state with just a little stimulation. “What about the harem in situations like this?”

“You didn’t expect this to happen, did you?”

I’m sure it’ll run out eventually… but what should I do after the afternoon?
