Growth (5) (Setsuna)

Every day I attended to a large crowd, enjoying harem sex.

But if I made use of bedroom time, where time flowed at 1/8, I could do all sorts of other things too.

With everyone, on a rotation, I also made time to spend alone, two-by-two.

Today I was spending time alone with Setsuna.

"… Mn…"

Setsuna leaned against me comfortably. How to spend two-by-two time varied by person.

Sex felt good, of course, but just sticking together doing nothing also felt plenty good.

… A calm moment spent together as brother and sister was, naturally, still a favorite of mine.

Even using the bedroom's 8x acceleration, Garumon-Battle-style training wasn't possible.

Skill counts and HP recovered only in real time.

But studying and reading were possible.

We were lazily reading. There were all kinds of books in this world too, and as I mentioned the other day, there was manga too.

Reading Lyuka's recommendation, Hard Worker Gaius — or reading the biographies of the Four Heavenly Kings, and so on.

I'd write the contents of those separately somewhere if I could.

"Haa…"

"Tired?"

"… Mn, taking a break."

We'd wrap up reading soon enough.

So… I slowly pushed Setsuna down on the bed.

"Ehehe… Onii-chan…"

Setsuna spread her arms and invited me.

I held Setsuna tightly. As we did, we both became naked and embraced even deeper.

Munyun, our naked breasts rubbed together pleasantly.

Chu, kuchu, chu…

And then, kissing Setsuna's matchless beautiful face… entranced, I tasted her mouth, sipping at it.

And further, crotch and crotch smoothly drew closer…

Nicha, kuchu…

The tip of my sensitive penis was wrapped in soft, hot warmth.

If I just embraced her further, with just that, my penis would be enveloped inside Setsuna's vagina.

If I did so, how much pleasure would I savor.

I knew this well, so driven by desire I tried to push my hips forward, but…

Chikuri, a pricking pain in my chest.

When I did this with Setsuna, there was always 1% regret amid the 99% pleasure.

Zu, zupu zu, ttzupu!

That said, there was no way I could endure this pleasure…

I rocked my hips back and forth intensely, savoring all of Setsuna's pleasure without leaving any. And then,

"Haa, aaaa, I'm coming, coming, I'm gonna come! Onii-chan…!"

"Setsuna, Setsuna…!"

Doku doku doku!

I released semen plentifully deep inside Setsuna's womb.

"Ehehe… Onii-chan, came lots today again, didn't you."

So saying, holding all my semen inside her vagina, Setsuna smiled rapturously.

"Yeah, Setsuna's inside felt so good…"

I smiled and answered. Completely my true feelings, but…

"But, Onii-chan, when you do it with me, you look a little pained — why?"

… My state of mind had been seen through. As expected of a little sister.

"No…"

This was a time to talk properly. Let's not dodge it.

"… Coming to this world, where sibling-doing-it isn't a crime, in this dream-like world…"

"Mm."

"… But in the original world it was taboo, right. No matter how much I liked Setsuna, I wasn't supposed to lay a hand on you.

"… The entire time in the original world, 'I mustn't fall for Setsuna, no matter how cute and charming, no erotic stuff allowed'…

"I kept telling myself that.

"… Somehow, I still have a bit of guilt left.

"Because for 17 years I kept telling myself absolutely no, and endured…"

I confessed my honest feelings.

"… Is that… weird?"

"A little weird, isn't it?

"A person who endures alcohol and tobacco until 20, when they turn 20 and drink and smoke — they don't remember the days when it was forbidden and feel guilty, do they?"

"… Put that way, certainly weird."

No such people existed.

"But people who come to a world where murder is OK feel guilty after committing murder, right?"

"But that's someone who wanted to commit murder so badly they came to a murder-OK world.

"So they wouldn't feel guilty, would they?"

"Hmm…"

Difficult.

"Or rather, if this were the 2nd or 3rd time it'd be one thing, but doing it this much every day, I think it's still weird to be thinking that. 100 or 200 times wouldn't be enough excuse anymore."

… Well, even if I didn't describe it every time, since we reunited and started having sex, we'd been doing it at least once every day, so…

That was well over 200 times.

Despite that, still — I couldn't deny it was weird.

"Well anyway, to me Setsuna is someone to protect. In place of those parents who could only do research and never came home, I had to protect and raise her — as a parent-substitute, I'd protected Setsuna with everything I had…

"And now, making her the target of pouring my desires fully into — I still can't get used to that…"

I made excuses.

"… But, in the end, you're a little excited by having sex with this kind of me, so you're keeping yourself from getting used to it."

"… If you understand that far, leave me alone…"

Yeah, well, this slight guilt made for good spice, kindling things particularly hot — I couldn't deny that, so I thought "you don't need to get used to it"… I couldn't deny.

… It had been quite some time since I started having sex, but I never got used to the pleasure of sex.

Every time, like I was having sex for the first time, I was thoroughly satisfied with intense pleasure.

Normally, you'd get a bit more used to it, I think.

For starters, when I masturbated on Earth… sure, it felt good every time, but the pleasure of my first masturbation was even more intense, I think. With each repetition, I dulled with familiarity.

Well, I'd never had sex on Earth, so sex might be something whose pleasure lasts forever.

But in this world, the magic filling a human body kept that human in their best, ideal state always.

That was true for aging stopping, and injuries and illnesses being quickly healed.

Since sex was pleasurable, and I'd like to enjoy that pleasure always, my mind probably never fully got used to sex.

That affected my mind too, and… this subtle guilt-as-spice might keep lingering forever.

"… Which means, Onii-chan, you of your own choice feel guilty when having sex with me, which means I shouldn't worry about it much?"

"… W-well, bluntly speaking, yes…"

Having my sexual quirks analyzed was, after all, a bit embarrassing…

"Ah, but Onii-chan… when doing it anal, you don't feel that guilty, right?"

"… Ah, that's… maybe so."

"Then… Onii-chan, put it… in my butt."

So saying, she bashfully offered her butt.

"… Setsuna… aah… with pleasure."

I'd ejaculated once but was already re-erect; I aligned my penis to Setsuna's butt and… worked it in.

Zutt zutt zu…

Aah, Setsuna's butt felt so good…

Inserting into a butt that squeezed mercilessly tight, while terrifically good, also somehow let me relax somewhere.

"Haa, ah, aah… Onii-chan, why don't you feel guilty doing it in the butt?"

"Hmm. Why, I wonder? Maybe because before, in some ero manga or something I saw a line like 'the butt isn't incest'…

"With that, I really wanted to do Setsuna's butt, but…

"In the end I was wimpy and couldn't take action."

"… I-I see… that's a wild line too, but…

"In that case, you could have done it on Earth too… I always wanted you to take action against me, Onii-chan."

"Setsuna… thank you. On Earth was no good, but from now on… let's do it lots."

"Mm!"

I accelerated the movement of my hips even more. My penis was rubbed intensely by the tight squeeze of her anus.

A truly wonderful pleasure. I sped up entranced, and,

Doku doku doku…

Plentifully, I ejaculated into Setsuna's intestines.

"Nhii! Inside my butt, with Onii-chan's semen, getting clean…"

Setsuna said happily. I felt rewarded for ejaculating.

After fully releasing my semen, I held her a while and kissed her passionately, kuchu kuchu.

"Onii-chan… knead my breasts…"

So saying, Setsuna pampered me.

"Fufufu, Setsuna's a spoiled child…"

I went along with Setsuna's whim, gently kneading her breasts.

Kneading her plump, large breasts felt very pleasant.

"… How is this world?"

I asked again.

"Mm? Best."

Setsuna answered smoothly.

"Yeah? How about TriAngel idol activities? Everyone's saying you don't seem keen on it…"

"W-well, standing on stage in frilly costumes is embarrassing.

"… But being together with Luna and Seika is fun, and I love music…

"It's not unpleasant. I'll keep doing my best."

"… Mm, do your best."

"Onii-chan, when you think about having sex with TriAngel's Setsuna, does it fire you up, or moe you up?"

"… Honestly, a bit."

"Aha… Then, I'll work hard."

She smiled happily.

That Setsuna,

Pikaaa!

her body suddenly began to glow.

"Oh, this is…"

I'd experienced this several times. The light of awakening. Setsuna was about to awaken to a new class.

… In games, normally this is generated after combat or upon level-up, but in this world it happened far more often after sex — was I imagining it?

According to the books, class change occurred by strengthening the bond with the Master.

So whether after combat or after sex, either way it'd occur, perhaps.

I displayed the system screen.

"Vir… eh, what's this?"

Embarrassingly, this word didn't exist in my chuunibyou knowledge.

But God Performing Princess I knew. Generally, classes with "God" in their name were basically Ultimate Jobs. Pure strengthening from the current Performing Princess, no doubt.

Since there were no other options, choosing No here was utterly meaningless.

I instantly tapped Yes.

In that instant…

Pikaa… parara…

Light danced over Setsuna's body, and… she'd awakened to a new class.

The changed skills were… numerous.

First, Bloody Masquerade → Calamity Masquerade. Single medium damage → area large damage growth.

… Even just this one was plenty amazing…

It dealt the same large damage every turn as a slip damage. It pierced defense too.

This Masquerade, fully exploited, was actually tremendously strong. And that had been greatly strengthened.

And on top of that, the real big one…

Soul Refrain became Divine Art - Crimson Quartet.

2 times → 4 times. 4 times per turn, and use-counts increased too. This was amazing.

If you used March of Passion 4 times, attack power and speed were both 200% UP. In one turn, this much buff was exceptional.

Furthermore, Radiant Symphony went 50% → 100%.

This too was tremendous. It was all stats. If you deployed it on 3 people at once with Crimson Quartet, this too was a Divine Art Messiah-class strengthening buff.

Up until now, Setsuna had been strongest against mobs but a bit awkward against tough opponents…

Setsuna might have leapt to our team's ace supporter at a stroke.

"How? Onii-chan. Am I going to be more useful to you?"

So she tilted her head and asked me… Cute.

"Yeah, of course. Setsuna… from now on too, I'm counting on you."

I held Setsuna and kissed her.

"Mm! Onii-chan… whether fighting or doing anything, I can be with Onii-chan…

"So, I love this world.

"I'll do my best for Onii-chan."

We passionately entwined tongues.

… In the midst of this, my penis got hard again.

"Then right away, let me taste the pussy of Setsuna, awakened as God Performing Princess."

"Aha. Gladly. Taste lots, Onii-chan."

Once again, I inserted my penis into Setsuna's pussy.

With Setsuna grown, was it my imagination that the pleasure had increased markedly?

But I think there's that aspect too. The higher the level, the higher the class, the stronger and more excellent the Garumon, the more pleasurable sex with them becomes.

It might be due to the magic dwelling inside, or it might be a mental thing, but…

If it feels good, that's fine.

Zupu zupu zupu…

Doku doku doku…

Faint guilt became spice for pleasure. While savoring supreme pleasure, I creampied plentifully into Setsuna's pussy, celebrating her growth.
