Progress with Shaina

"… Gufh…"

I slumped forward, defeated.

Another loss… Against Shaina in the mock battle, this made six losses in a row.

We'd been making full use of the 8-hour recovery on Garumon skill counts and HP to run three mock battles a day, repeating it for two full days…

"Haa, haa, haa…"

Shaina was breathing heavily, shoulders heaving. I'd managed to push her into a corner each time… but I couldn't quite close that last step.

"… Are you holding back?"

So Shaina complained.

"It's not that I'm holding back.

"It's just that I'm fighting on the premise of not knowing Shaina's skill loadout…"

"… Right. Even knowing I'm going to call Lakshmi, you go for the first-turn all-out blitz."

"Garumon battles are basically once-in-a-lifetime encounters. A case where you go in with full information on your opponent is basically nonexistent.

"So you have to be able to fight on first sight. And if you can't manage without that info, it's pointless.

"… Well, among S-Class Masters, since the matchups are fixed by rank, you might end up fighting the same opponent many times with each side knowing exactly what to expect."

"… Well, that's true. In S-Class you fight the same opponent over and over."

"But my objective is to win the upcoming Julian match and Eclair match.

"… If I beat Julian and Eclair and grab 16th, I'll never have to fight Eclair or Julian again."

"Eh, Eclair becoming a companion aside, doesn't Julian still get matched against you in the S-Class tournament?"

"Nah, in this tournament, I'll be 16th. Shaina will be 21st, right?

"Then if Shaina climbs up to 17th, you'll get matched against me, right?

"And when that happens, I'll have to be the one to win!

"… And so Julian can never get past Shaina for life, and will never fight me ever again."

"I see…

"… Hmph. By that point, I'll be the one winning! So in the next S-Class tournament there's a possibility I get matched against Julian!"

"No, by then Ruria and Iv will be there. Either way, you won't get matched against Julian."

… Or perhaps the children of Vega from the Sirius bloodline, or a yet-unseen star will debut.

"I see… well, if that's the line of thinking you're fighting with, then sorry for the 'holding back' line."

"No, I'm sorry for the misunderstanding too.

"… The fight itself, I'm absolutely not holding anything back.

"Honestly, I'm super frustrated. Why can't I win…"

"Why, well… my level's higher, and if you're not using prior knowledge, of course you can't win…"

"No, in the end, my instructions aren't enough either, and everyone's growth is short too.

"… Between the Ursula fight and the mock battles with Shaina… it was about time everyone advanced another step, but…"

… And as I was saying that, suddenly everyone began to grow, here and there.

I'd cover the individual growths separately.

It made me wonder whether, if everyone grew this rapidly right before the decisive battle, they could really use the new skills to their full potential.

But there was no doubting it was welcome.

The result…

"Haaa… that was close…"

I succeeded in pushing Shaina to the very edge. I downed Shaina and Shita, but I barely failed to down Carla…

Well, I didn't win, though… ten losses in a row, even I felt pathetic…

… Well, eventually, winning wasn't out of the question.

Everyone had advanced a stage from before, and I'd been able to catch up considerably to that once-distant back of Shaina's.

That I still lost wasn't because I'd held back, definitely not, but…

I couldn't deny that somewhere in my heart I'd felt a touch of "if I win and have sex with Shaina, that would be a little bit of a waste."

This current best-friend relationship was so comfortable, the feeling of "if it could just stay this way…" couldn't be denied.

I really loved sex, but a relationship without it — with Shaina, I might not really dislike that.

Well, if that weren't the case, then with my wonderful beautiful-girl companions, where I could have sex whenever I wanted, I wouldn't be making a point of holding back like this.

… But tomorrow, I was scheduled to head to Ursula.

Magic-ash sweep — you couldn't dismiss it as just cleaning. A Great Magical Beast could appear and attack, so there was even a danger to life. That was why I wasn't leaving it all to Ursula; I planned to go too.

For three days there, I'd be standing by in Magical-Beast territory, waiting for a Great Magical Beast to appear.

There was no guarantee a Great Magical Beast would conveniently appear in those three days.

If it didn't, then during the tournament I'd have to leave it to Ursula. If a Great Magical Beast came out during that time… it really worried me. But Ursula would surely be fine.

If nothing happened until after the tournament ended, then we'd seriously begin the magic-ash sweep. The sweep was said to take days to months, so it was a long-term operation.

Of course, even with me absent, the rest of the team would continue mock battles to the limit, but mock battles without me wouldn't really be serious matches — just Shaina overseeing things.

After that, the decisive battles would finally begin. We'd rest from the day before, getting in top condition.

That meant the next mock battle was the last where I could seriously go up against Shaina before the decisive battle.

… And in that last one… if I lost, having sex with Shaina would be put on hold for a while.

If I fought as I was, treating it as first-sight, honestly… it was a touch worse than fifty-fifty.

If I fought with full anti-Shaina prep, I could win convincingly.

Which to pick… I agonized over it.

While I was musing on that, resting a bit in my room…

"Naoto, you in?"

Shaina, along with Carla and Shita, came over.

"What's up? The three of you."

"Yeah… During the break, we were thinking the three of us would have sex."

"Mm."

"But, um… Naoto, in the recent mock battle, you pushed us to within a hair, right?

"And we got to talking, like, would it really be okay not to give you some kind of reward."

"… Mm."

"… The three of us having sex… if we let you watch, would that be a reward?"

Such a proposal.

"Mm, it would… You'd let me see?"

"… W-well, yeah… A-all right. We'll show you."

And so, on what whim I didn't know, Shaina let me see them having sex.

First, the three of them got naked… As far as being naked went, we'd all been in the bath together by now, so I'd already seen plenty.

But seeing them naked right before sex was a first.

Shaina's penis, Carla's black penis — both were rock-hard and erect, expectant of the sex to come.

Shita… revealed her undeveloped body.

For her still-immature body, even Shaina's and Carla's penises, which were a size smaller than mine, looked still too large.

"Ehehe… it's fine. Just watch…"

So Shaina said, spreading Shita's legs wide and inserting her penis into that small slit.

Zu, zupu… zu pu pu…

"Ha, a, aah… it's good, feels good… Shitaaa…"

Shaina was panting with a lewd expression, different from her usual mischievous look.

"Nn… Shainaa…"

Shita too, looked good, her face melting in pleasure.

Zuchu, zuchu, jupu, ju…

The two of them's groins played out lewd sounds.

"… Goku…"

I was enraptured, watching.

"… Naoto."

And then, Carla came over to me.

"If you'd like, I'll use my mouth."

"Eh… i-is that okay?"

"It's fine. This is a reward for Naoto. Watching only and not getting to ejaculate is torture.

"I know that pain too."

"… Thank you. Then, I'll trust you with it."

So saying, I exposed my penis.

Carla wrapped her ample black breasts around my penis… and took the tip that poked out from her cleavage into her mouth.

"Aah… that feels good, Carla, thank you…"

I stroked Carla's curly hair.

The slightly tight curls wrapped around my fingers, but came undone smoothly.

That felt nice…

I'd love to be allowed to shave Carla's hair down there too…

While I was thinking that, stroking Carla's hair, I enjoyed the pleasure of her lips and breasts.

Eventually…

"Nn, ha, a, aaah…!"

Doku! Doku! Doku!

"A, aah…"

Watching Shaina ejaculate, my excitement hit its peak, and I came inside Carla's mouth.

Shaina ejaculated thoroughly inside Shita's small pussy.

"Nn… amazing… thick semen… mana is dense… good semen."

Carla complimented me like that. Juru, she swallowed it down.

"All right, next… Carla, let's do me."

Shaina invited Carla over.

She spread her legs and showed off her pink slit.

Shaina's slit was already drenched.

"Mm… I'll be there."

So saying, Carla went over to Shaina.

In her place, Shita came over to me.

"Fufu, next, I'll do the service for you."

So Shita said.

"Eh, um, is that okay?"

"It's fine. This is the reward for Naoto-san who's been working hard.

"… A loli like me is no good?"

"As if — nothing of the sort."

"Ehehe… thank you very much. But I can do this kind of thing too."

So Shita said, and closed her eyes and muttered a prayer…

Ka!

She brought down a god.

Gugugugu… boin!

Instantly, her body rapidly matured into an adult shape, those breasts becoming purun, purun full and luscious… incredibly, hugely large.

Lakshmi mode.

"Ehehe… with this, I'll service you.

"Aha, just as I thought, bigger than my small form."

"U, uu…"

Y-yeah, this form was dead-on, right in the middle of my strike zone. The original form was totally within the strike zone too, but…

This was a monster fastball.

Shita's now-luscious breasts squeezed munyun around my penis… and her mouth sucked on it.

"Aah… Shita…"

While she did, I stroked Shita's soft silver hair.

Doing that, I looked over at Shaina.

… Carla's tough black penis was burying itself, zubu zubu, into Shaina's lovable slit.

"A, a, aaah… Carlaa…"

Shaina panted sweetly.

… Wow… that Shaina. My bright, energetic friend Shaina… now she looked completely… like a girl.

I mean, she'd been a girl from the start, of course, but… now she was completely, almost fragrantly… a woman.

Zupu, nicha, kuchu, nupu…

"Ha, a, aaah…"

Swinging her breasts, her own penis rock-hard and erect, Shaina arched in pleasure — truly erotic, incredibly erotic…

Aaah… I'm jealous, I want to do it too.

… A-actually, watching like this, the thought of "we're best friends so we shouldn't have sex"… was starting to look idiotic.

I really did want to too! I wanted to make that erotic Shaina arch in pleasure with my penis…!

I felt that, fiercely, maddeningly so.

"Nn, nn… t-too big… my, my mouth's getting tired…"

I was so rock-hard that Shita was struggling to suck. Eventually…

"Ha, a, aah…"

"Nn, nn…!"

Doku! Doku! Doku!

Carla ejaculated aimed at Shaina's womb, and Shaina, at the same time, ejaculated from her penis.

At that stimulating sight… I too ejaculated thoroughly into Shita's mouth, making her cough.

"Goho! Goho! Goho… t-the force is too much…"

"S-sorry, Shita. I couldn't help…"

"Geez…"

"Shita, next, go to Carla."

"Mm… see you later, Naoto-san."

And so Shita and Shaina switched places.

… After having sex with Carla, leaking lust-fluid and semen from her groin, Shaina came over to my side.

The smell of the semen Shaina had ejaculated drifted over.

But futanari girls' semen, somehow it smelled good. Was that just me?

I'd become quite the seasoned futanari-fanatic…

"Ehehe… how was it? My sex."

Shaina asked.

"Y-yeah… it was super erotic, cute… attractive. I… wanted to do it too. Really badly."

"O-oh, really. H-hmm… Hehe…"

Shaina smiled, looking pleased.

Still transformed, with her luscious figure, Shita let Carla insert her penis.

Zu, zupu zu, zu…

Carla swiveled her hips, vigorously thrusting in and out of Shita. The two of them panted.

"Carla and Shita have sex too, huh."

"Ah, didn't I say? The three of us are normally lovers. Of course we have sex in any combination.

"After this, if I put it in Carla, that'll be all the combos, right?"

I see, so among the three they enjoyed four combinations.

Watching Carla and Shita have sex… naturally, I got excited.

Being left hanging like this really was tough.

"… Shaina too… will you do me, with your mouth?"

"… Y-yeah. Of course. Same as Carla said. Being a guy too, I know damn well how tough being left hanging is."

And so, Shaina crouched down at my groin.

"… Naoto's is big. As expected of a guy… it's tougher than mine or Carla's."

"… Shaina…"

"I don't really like guys'… but…"

Shaina opened her mouth wide and…

"If it's Naoto's… I don't dislike it at all."

She took it into her mouth.

"Nn, ham, ju, jupu…"

Carefully, eagerly… Shaina sucked on my penis.

Taking it all the way down her throat, swallowing deeply… then bringing it back to her lips…

"Nn, nn… so big… nn, nn…"

Ju, jupu, ju, jupu…

Carefully, carefully… twining her tongue, sucking.

"Shaina…"

I gently stroked her bright, light-like hair.

"Naoto…"

Jupu, ju, jupu…

Shaina serviced me, looking like she felt good too…

Aah… how cute. Shaina…

She was a friend… my best friend… But still, Shaina was cute. Very attractive.

If we had sex, would we no longer be best friends? But I wanted to. So badly. Such an attractive girl, not having sex with her… no way. I couldn't bear it.

Doku! Doku! Dokun!

… And then, I released abundantly into Shaina's mouth.

… Up to now, I'd been trying not to think of Shaina as a target on which to pour my lust, like this clearly.

But now I had no choice but to be conscious of it.

I really… loved Shaina.

I wanted to have sex too… Lots and lots.

"Fua, a, aaah…"

Letting semen leak from her mouth, Shaina was in a daze.

"… A, aah… w-well, next… I'm up… to have sex with Carla, right?

"During that time, um… do you want to… have sex with Shita?"

Shaina proposed.

"… Thank you. But the girl I most want to have sex with right now isn't Shita… if I had sex with Shita in this state of mind, I think it'd be rude to Shita."

"Eh, t-that means…"

"… Hey, Shaina. While you're having sex with Carla… can I touch your breasts?"

"T-that's fine… no problem…"

"Kisses too, okay?"

"Eh, I-I just had you ejaculate a bunch into my mouth, you know?"

"I don't mind that."

"… T-then it's fine, but…"

I pushed Shaina down onto the bed, kneaded her breasts, and… kissed her.

"Nn, ham, nn, Naoto, Naotoo…"

Juru, chu, churu, rero, chu…

Shaina's lips were very sweet, melting like… my brain went numb, they were that sweet.

I'd just ejaculated, but it didn't matter at all. Right now, Shaina's lips were just unbearably dear.

And I kneaded her soft breasts, pinched her nipples, gyu and…

I wanted to make Shaina feel so, so good.

"Ha, ha, aaah…"

Biku, bikun, Shaina was climaxing lightly. Her penis was rock-hard.

"… Shaina… feeling it so much…"

"Carla. Shaina's penis… make her feel good."

"Mm, got it."

And so, Carla brought her black butt close and slid Shaina's penis… into her own pussy.

"A, ha, aah…"

Stimulated at her breasts, mouth, and penis, Shaina panted sweetly.

… Aah, and if I added to Shaina's pussy stimulation from my penis, how much more cutely would she pant for me.

I couldn't bear with this any longer.

Before the Eclair match, I'd absolutely win… and hold her. So I resolved.

Even if that meant we'd no longer be best friends?

That was the only thing that worried me.

But…

"A, aaah, ah…!"

Byuku! Byuku! Byuku!

Shaina and Carla ejaculated at the same time.

If I couldn't see that erotic expression of Shaina's, I couldn't stay only best friends.

Would having sex change my and Shaina's relationship, or wouldn't it?

I was uneasy…

But the hands of the clock could only move forward.
