This is the second one

Under the blue sky, I'm doing something naughty with my childhood friend.
This sense of sin only adds to my excitement.

"Mm..."

Chiyu lets saliva build up in her mouth and pours it into the valley between her breasts.
Even just the softness of her breasts was enough to make me feel like I was about to explode with happiness, but the added slickness acts as a lubricant.

Instantly, my pleasure spikes, and I can't help but tense my hips.
If I just enjoy this pleasure, I won't last even a few seconds.

She doesn't mind getting dirty and kneels on the ground, continuing to serve me with her upper body bare.

I held the stick between my fingers, kneaded the milk, and moved it up and down.

With each movement, the sensation and pressure inside changed, sending an indescribable pleasure surging from my lower abdomen to my brain.

"Nn... Nn, nn. Sou-kun, you're so 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 were also her genuine feelings. The effect of the "Muscle Strength Enhancement" was truly immense.

Still, if there hadn't been any factors to excite me, I wouldn't have gotten this hard.

"Chiyu's breasts are so sexy."

"If it makes you happy, I'll be as sexy as you want."

Chiyu said, looking up at me with her sapphire eyes.

And she looked down at the umbrella sticking out from between my legs.

"H-Hey, Chiyu, you wouldn't—"

"Boys like this kind of thing."

She then kissed the umbrella.

"Guh...!"

Next, she opened her small mouth as wide as she could.

"Given how big you are now, this is possible. Nn... mm."

She put the tip of the stick in her mouth.

Instantly, it was enveloped in something warm and slippery.

"――――h?!?"

His hips jerked from an indescribable pleasure.
Even though it wasn't meant to be entered, it felt as if it were meant to be.
The combination of guilt and pleasure was overwhelming, making his eyes start to spin.

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

Chiyu probably did it on purpose, making exaggerated slurping sounds as she began her fellatio in earnest.

The shaft was enveloped by her breasts, and the head was licked by her.
I don't know if this is the right way to put it, but what a luxurious sensation.

Without taking a single break, Chiyu continued to serve him with devotion.
If I could feel the ultimate pleasure, that was all that mattered to her, an overwhelming amount of love.

It wasn't just the act itself, but also the depths of her childhood friend's heart that he felt.

All of that excitement was converted into a thick, white fluid that was rapidly increasing, waiting to be released.

It was obvious that this couldn't last much longer.

"Chiyu... soon...!"

"Squish... squish... squelch, slurp... Don't stop. Keep going. I'll take it all in my mouth... I'll take it all."

Her service became more intense, and I reached my limit immediately as she tried to milk me.

"Guh...!"

I thrust my hips hard, letting my desire take over and release the white fluid.

"Mmm...!? Mm, mm, mm, mm."

Chiyu responded to each pulse of my member.
　The frequency was unlike anything I'd ever felt before, and the pleasure accompanying my ejaculation was more than double what I usually experienced.

That means she had taken in a large amount, but she didn't let go of what she had in her mouth, and she kept it there until the end.

In fact, she seemed to be urging me to release the last drop, as she licked the tip of my shaft with the tip of her tongue. My cock twitched in response, and she slowly milked out the remaining drops.

Despite the pleasure I had just experienced, all I had done was stand there.
　Thanks to my childhood friend's dedication, I had just gone through the ultimate experience, where I was completely drained without even having to move a muscle.

After I had finished, she slowly pulled her mouth off my shaft and opened her mouth toward me.

"Ahnn..."

Her mouth was filled with a milky white liquid, mixed with her saliva, and it was about to spill over.

Seeing that I had just released that much, and that she had taken it all in without spilling a drop, I felt an even greater thrill.

Chiyu closed her mouth and, unbelievably, began to swallow.

「N-N, Chiyu...! ?”

It was indeed a man’s dream, but it was obvious that it wouldn’t taste good.

I had told her not to force herself, but she stared at my face the whole time and slowly, but steadily, finished drinking it.
　Because of the volume, she had to swallow it in several gulps, and it took her a minute or two to finish.

Still, when she had finished drinking it all, Chiyu 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 nice?”

I panicked at the sight of her worried face.

“N-No, I’m honestly really happy and excited, but… It probably tasted awful.”

The pole didn’t even go through the process of softening before becoming hard again.

Not just from the magic effect, but also from Chiyu's actions.

"Uh. Super bad."

"Y-Yeah..."

"But... If Sousuke's happy, I'll do anything."

"Chiyu..."

Her words make the stick tremble.
　Chiyu didn't miss it.

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

Chiyu casually reaches for me, rubbing it while asking.
　She did it for me the first night, but it's only the fourth day of our desert island life.

That said, what an incredible rate of adaptation. What an incredible growth rate.
　An inexperienced childhood friend had, in just a few days, acquired a lewdness that even succubi would envy.

"I'll devote myself to you, Sou-kun, with everything I have. So, become my captive."

Captive? As if.

"I already am..."

"――――!"

Chiyu was surprised by my words, and then...

She smiled clearly, looking happy.
　Her smile was as innocent as it was when we were children.

"I'm happy. But if that's the case, I'll make you even more of a captive."

However, a moment later, it turned lewd.

Chiyu stuck out her tongue and licked the tip enticingly.

"Choose, Sousuke. 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, it was clear she was holding back.

"I'm sorry..."

"No, it's all my fault. For twisting your sexual preferences with my big breasts, I'm sorry."

It seemed she was joking.

"...Yeah, it's all Chiyu's fault."

I laughed, and she smiled back.

"Uh-huh. I took my medicine. I cast the enhancement spell too."

Speaking of which...

"...Hey, this doesn't seem to be losing its effect at all. How long is it going to stay this big?"

Chiyu looked away.

"...Is there something wrong with being big?"

"You don't know either, huh...?!"

"Maybe if I produce a lot, it'll stop..."

She's just hoping for the best...!

"Hey, hey..."

「Then, should I stop?」

I thought that was a cheap question.

「...No, please.」

「Understood.」

After that, Chiyu squeezed me a few more times in a short period, but the effects of the 'Muscle Strength Enhancement' didn't seem to be wearing off.

「This is something I can't handle alone. I need everyone's help.」

「Don't say it like a strong enemy has appeared...」

I wouldn't lie and say I wasn't happy to be growing, but with my energy still enhanced, even the slightest stimulation put me on edge for combat.

「This is the time for the harem.」

「You didn't expect this, did you?」

I wonder when it'll run out… What should I do after lunch?
