Vivia and Miria's First Night

The victory celebration for winning the Eclair match. Everyone seemed to be having a good time.

Now then, with the party in full swing… it was about time for the main event.

"All right. Vivia and Miria worked so hard this time… I have to give them their reward."

"Yes! Goshujin-sama!"

"Yes! Goshujin-samaa!"

Vivia and Miria threw their arms around me, looking so happy.

So cute…

Chu, chu…

I held the two of them, one in each arm, and gave each of them a kiss.

It hadn't been all that long since we'd met, but both of them had plenty of affection for me.

Their LV was over 50, too… so it was fine!

The biggest issue was probably their ages, I felt, but I decided not to worry about that.

In this world, once you'd awakened your power, you were already an adult. In other words, no problem.

I touched Vivia's soft, modest little breasts, and then Miria's plump, abundant huge breasts.

"Haa… Goshujin-samaa…"

The two of them let out sweet, blissful sighs.

The outfits the two of them wore were the skintight suits they'd worn since the monster territory.

If I asked them to wear Spirit Garbs or Lewd Garbs, both of them would happily put them on.

… But since this was their first time, I wanted to have sex with them in these outfits they'd been wearing from the start.

These suits were plenty erotic and appealing in their own right, after all.

That said, the suits themselves apparently had no special effects to speak of. So for serious combat I'd have them wear Spirit Garbs and the like.

… These suits were cute too, so maybe I should modify them to switch into Spirit Garbs with one touch.

That was what I thought.

Shuru, pasa, pasa…

I wasn't quite sure how to take them off, but there was a zipper on the back that let me undress them.

From the clothing of our original world, to fully naked, not a stitch left…

The two of them were so beautiful.

Vivia with her soft little breasts, and the bountiful Miria…

I couldn't help preferring Miria after all… No, no, Vivia was incredibly cute too.

I held the two of them close and latched onto each of their breasts.

Miria's breasts were tremendously full, but her nipples were still smooth and undeveloped, a sign she was still growing.

Vivia was completely in the middle of growing.

They were still small, but… maybe they were just a little bigger than when we'd first met?

I figured they'd grow even faster from here on.

I was really looking forward to it.

I fondled their breasts, kissed them… and their breasts again, their bellies, their navels…

While raining kisses all over their bodies, I stroked and caressed their soft skin.

"Fuwaaa… Goshujin-samaa…"

"Goshujin-sama, Naoto-sama…! I-it feels good…!"

Biku, biku, pikun…

The two of them reacted so sensitively. They were from the monster territory, but there didn't seem to be anything different about them from the girls of this side.

Their delicious bodies, their soft breasts, the lovely scent of their skin…

Every bit of it was top-class, but so far there didn't seem to be anything about them being Demonkin that set them apart.

… Still, I'd savor them all the way to the end and find out for sure.

I thought I'd caressed them plenty… but even I had to admit I was standing up to a dangerous degree.

I'd done it over forty times so far, but now that I'd become an S-Class Master and could manage as many as fifty times a day, I was still in peak condition.

In this fiercely aroused state, I worried whether it would really be all right to force myself into Vivia's and Miria's tiny slits.

… Well, on that point, all I could do was trust in the toughness the two of them had as Garumon, as Demonkin.

Which one should I start with? Maybe Miria, who was a bit more developed, should go first, but…

Vivia was the one who'd joined me first. Maybe Vivia should go first.

I spread Vivia's legs open and pressed my penis against her.

… Whoa, the criminal stench is dangerous.

Vivia's body still hadn't developed enough, and she was a bit, well, plump and soft.

Miria, thanks to her breasts, had grown into a much more girlish figure, but…

In short, Vivia looked like a little girl.

In terms of having sex with a girl with a little-girl body like this, she ranked after Lyuka, Colette, and Shita…

But Lyuka's and Shita's actual ages were no problem.

Colette had grown quite a bit too…

On that point, Vivia was the most criminal of all.

I-is this okay? Is it really okay to go through with this…?

I grew anxious and gazed at Vivia's face, but…

"Goshujin-samaa…"

… Whoa, she's… making such a lewd girl's expression.

Despite her still-immature loli body, Vivia already seemed completely ready and willing…

If she could show such a lewd, cute expression, then I could do it, I told myself, making excuses inside my own head.

I couldn't hold back from doing it anymore.

Zu… chu…!

Whoa, t-tight…!

No matter how I thought about it, the size was… Vivia's there was still an undeveloped slit, and it looked smaller than my thing.

Even spread as wide as it could go, there was no way it would fit…!

I-if it really wouldn't fit, then I'd just have to hold back…

I grew anxious like that, but…

Gu, gugugu…!

Vivia's there was somehow… stretching. It was widening with all its might, trying so hard to swallow my thick thing.

… If it ever tore, that would be terrible, but a Garumon protected by HP shouldn't be hurt so easily.

The only thing that could be hurt should be her hymen.

… And so, trusting in this world's system, I pushed my hips forward further.

The thickest part at the tip somehow managed to slip past the narrowest part at her entrance.

If this works…

Thinking that, I pushed my hips in, but… so tight! Incredibly tight! Gyuuu! It clamped down on me so intensely it felt like it would tear me off.

And that… felt unbearably good! It was a bit painful, but it was a pleasurable pain!

"Ha, a, aaaa… G-Goshujin… samaa…!"

Vivia must have been in considerable pain, letting out groans of agony.

But it didn't split open and bleed; she was somehow managing to swallow my thing.

If this kept up, I should be able to make it to the end.

I stopped many times along the way to kiss her, stroke her breasts, and caress her body, trying to make it even a little easier for her.

… But when I did those things, Vivia's too-tight insides tried to push my thing back out, and unless I held her down and forced it in, it seemed like it would slip out again.

Caressing her to make it easier would cause it to nearly slip out, so I'd push it back in. Repeating that process, I couldn't tell whether I was actually making it easier or not.

Still, advancing little by little, deeper and deeper, gaining and losing ground, seemed easier on her than shoving it all in at once.

I wasn't sure, though.

My whole body damp with sweat, I pushed into Vivia bit by bit.

It was just so tight, so tightly squeezing, it was almost painful… but it still felt good, and there was no way I could stop partway now.

Zu, zu, zupu

At last, I broke through Vivia's hymen.

Just the faintest trickle of fresh blood. My penis had broken the one place a Garumon protected by HP could be hurt.

All right, from here, deeper still.

Zu… zuzuzu… zuzu…!

I don't think I really sped up from there. But with that slight resistance of the hymen gone, I pushed into Vivia just a little faster, bit by bit.

And then…

Zu… pu…!

It felt like it had taken an incredibly long time. After a long while, my thing was finally buried all the way to the base inside Vivia.

… Wasn't this pretty reckless too? Vivia's small body… though, she was 140cm, so not such an extremely tiny loli body. She was twelve, after all. Regardless of her figure, in terms of height she should have developed to some degree.

… But whether it was really okay for her to take me all the way to the base, I honestly didn't know.

Vivia was barely able to breathe, looking like she was suffering.

But…

"It's all the way in, Vivia. Now you and I are one."

When I said that, Vivia gave me a happy smile.

… I couldn't prolong her suffering any further, or rather, I was already at my limit.

Doku, doku, doku!

Before long I ejaculated.

Naturally, ejaculating in a space without a millimeter of room to spare, there was no way I could keep it in afterward.

If she'd felt it enough for her cervix to open wider, I should have been able to pour it into her womb, but Vivia didn't have that kind of room to spare.

The moment I ejaculated, my penis slipped out.

"Higun, nhaaa!"

But for a Garumon, being ejaculated inside is said to feel tremendously pleasurable.

The dense magic power being poured into her vagina and womb is felt as intense pleasure, apparently.

For Vivia, who must have been in such hard, painful straits, it should have served as a reward for working so hard.

"Haaaa…!"

I'd poured plenty of semen into Vivia's small little pussy…

But the only bleeding was the slight bleeding from her hymen breaking; she'd shown the toughness befitting a Garumon.

She worked so hard.

"… Vivia, thank you. That felt… really good."

"Goshujin-sama… I'm so happy…"

Vivia narrowed her eyes in rapturous delight.

… Well, doing it over and over in a row like this would surely be too much of a burden on her.

I'd have her rest for now.

And so, next was Miria.

"Ah… Vivia, you worked hard. Now it's my turn…"

Though there was some anxiety, Miria's expression sparkled with anticipation that outweighed it.

I was a little relieved too. Since she was a bit more developed than Vivia, it shouldn't be quite as tight as Vivia.

Thinking that, I pressed my penis against Miria's vagina, but…

I'd been naive. It was incredibly tight! Almost no different from Vivia's.

Or rather, even Miria's vagina was already past the limit. Vivia had just been pushing past her limit to endure it…

Even Miria felt narrower than the thickness of my thing!

The fierce squeezing was a pleasurable pain. But thanks to the practice with Vivia, I could push in deeper, deeper, at a slightly faster pace than before.

… And along the way I could fondle Miria's voluptuous breasts to take my mind off it a little, too.

After all, having a girl as developed as Miria really does make sex easier…

Well, I figured Vivia would get good at it too once she got used to it.

Once I'd had a taste, choosing not to do it was no longer an option for me.

Tight… hot… squeezing…

Once again, sweating an oily sheen over my whole body, savoring intensely a pleasure I couldn't tell was agony or ecstasy, I pushed in little by little, little by little…

Putsun…!

Eventually, I pierced Miria's hymen too.

From there, even slower, bit by bit…

So tight! I wanted to get deep fast, but it was too tight to move. Resting again and again… it felt good enough to make me want to ejaculate, but I knew that if I ejaculated here I wouldn't be able to go any deeper, so I held on desperately.

So… it feels too good!

Could feeling this good really be unique to Demonkin?

It seemed to feel better than with a human… though I figured that was just because every single time I have sex with anyone, all I can think is that it feels the absolute best.

But still, it really did feel the absolute best.

"… Miria…"

"Ah, Goshujin-sama, Goshujin-sama…"

Miria called my name in a pained, whispering voice.

… Cute. Too cute…

I held Miria tightly, kissed her… and poured my passion into burying my penis all the way to the base, deeper still.

And then… at last, it sank in all the way to the base.

"Goshujin-samaa…"

"Miria… it's in."

And with that, I was already at my limit. Too tight. Too hot. Too good…!

Doku, doku, doku!

I ejaculated again.

"Haa, a, aaaaa!"

Miria let out a cry of pleasure too. It must have been tight the whole time, but maybe this let me give a little something back.

My penis slipped out as I ejaculated…

Doku, doku, doku!

As if to wring out every last drop, Miria's tight pussy clamped down and sucked it up.

"Ah, aaaa…!"

Toro…!

Miria's incredibly tight pussy let my semen overflow little by little.

… Inside that narrow vagina, it seemed the semen couldn't stay put.

A faintly pink liquid, mixed with the fresh blood of her deflowering…

The fulfillment of having had sex with Vivia and Miria, the two cutest girls imaginable, welled up in my chest at last.

… Well, I'd leave it here for today.

I held the two of them close and stroked their heads, praising them for working so hard.

"Goshujin-samaa… it hurt, but… I'm so happy…"

Vivia said that in a coquettish voice.

"… Yes, really… I was so happy.

But it really did hurt…"

"S-sorry. It was only me feeling good…"

"… I-it's fine. If you feel good, Goshujin-sama, that's our greatest happiness of all.

… On that note, please let Nami and Kanna taste this happiness soon too.

As the rivals we fought, we do care about them, you know."

"… Yes, I'll do my best…"

If only Nami would just get in the mood… no, I shouldn't pass the blame.

"So then, doing it one more time would be… too hard, I guess?"

"I-if you wish it, Goshujin-sama, I'll do my best!"

"M-me too. If you say you want to, Goshujin-sama, then as many times as it takes…!"

"Ahaha, it's fine, it's fine. I'm very satisfied for today.

… Thank you so much, both of you.

But from tomorrow on I'll have you work hard again… I want to do your butts soon, too…"

Saying that, I poked a finger into each of their anuses.

"Haaaa…"

"I-if it's there… we could do it right now, you know?"

The two of them clung to me, faces melting, with rapturous expressions.

"No, tomorrow.

… For today, watch everyone else's sex and study up.

If you'd like, I think it'd be good to have sex with someone a little smaller than me, like Haru, Shaina, or Ursula, to get used to it."

"… I still don't want to have sex with anyone besides Goshujin-sama…"

Miria was reluctant.

"If you wish it, Goshujin-sama, then I think it'd be fine for me to have sex with Haru-san or Ursula-san and the others…"

Vivia was eager, and their opinions split.

It might have simply been that Vivia, since she'd been so tight, strongly wanted to get used to it starting with something a little smaller.

"Yeah, please give it a try."

"… Fufufu, and to think we came here meaning to kill Ursula.

Before we knew it, we're trying to have sex with that very Ursula. How funny.

… All right. I'll have sex with Ursula too.

If we have sex with Ursula, the exchange of each other's magic power might lead to some good result."

Indeed, at first they'd intended to kill her and eat her corpse, after all…

Compared to such a terrifying exchange, this was a far more wonderful one, I thought.

There were many good things that had come from my coming to this world, I felt…

But this exchange between Vivia, Miria, and Ursula was without a doubt one of the wonderful achievements I'd brought about.

"Fufufu, did Naoto hold thee? How good for thee, Vivia, Miria."

"Yes, Ursula-sama!"

"Ursula-sama, next time we want you to hold us. Once we've rested a while…"

"Mm-hm, very well. Naoto's is large and tight, no doubt.

Mine is not so much. Let me get thee well accustomed, and then have Naoto hold thee once more."

"Yes!"

"Yes!"

The three of them flirting together were so cute and lovely.

And so, I welcomed a wonderful first time with Vivia and Miria.

And with that, the victory celebration party came to an end.

"Haaa… I'm satisfied… It was the best party!"

The guest of honor, Shaina, was thoroughly satisfied too. I'd gotten to have plenty of sex as well… I had so much fun.

"Let's do it again! Maybe next time I'll be the one to host!"

There were some bothersome rituals involved, but those very restrictions made it all the more exciting, and Shaina and I had completely fallen for hosting parties.

We promised to do it again soon.

… Well, party or no party, from now on Shaina would come to my house every day, have plenty of sex, and we'd keep spending fun days together regardless.
