[Sylvia]

*****

Turns out, clearing an A-rank gate wasn't that much for us, but it was a pretty big deal to the general public of this world. The news aired just an hour after we cleared it, and the news reporter was so excited as well.

Our information—things like names and faces will be publicly available in a day or so, which is fine. We don't really care about privacy and all that, this is just a fake world after all. Emy even hatched the idea of fucking on television when we're all about to graduate from this world, which... I fucking approved almost instantly. That sounds so hot.

Talk about Emy, she also mixed her cum in my cookie batch yesterday, what a genius. The cookies were so good I thought she put drugs in it, but turns out I was just a cumwhore.

And I also made my decision regarding becoming Sariel's fuckt- sex friend. I told my fiancés that I wanted to hook up with the lustful dragoness, the main reason being her semen could further enhance my strength.

Now, I could just have her masturbating and then pour all the cum inside my womb, but I... I seriously want to experience the tentacles of hers. Who wouldn't want to?

Either way, they said that they needed a day to consider, and after a night of me being brutally fucked, it is now the next day. My fiancés should be discussing the sex friend offer right now. For me, I am in Sariel's room.

''Are you ready?''

''Yes.''

Sitting on Sariel's bed, she is about to teach me the way to acquire [Heart of Fire].

[Heart of Fire] is a method that basically... Cheats the system. So you know how any living being bigger than an ant cannot store mana inside their body because cells constantly change, right?

But this method could somehow turn your heart into something that can store mana.

By the way, although it is called [Heart of Fire], the heart itself does not burn nor contain flame. It's just a metaphor for dense and hot mana flowing inside the heart.

And by having it, your mana control will get a boost, plus the convenience of having an extra mana reserve cannot be excluded.

''How does this work exactly?''

''It works for us because we dragons can morph our bodies as we like, so turning our hearts into mana reserves is easy enough.''

''But I'm not a dragon?''

''I will turn you into one.''

''...What?''

''Only your heart, as it is the most effective organ for storing mana. Besides, your body will be overloaded if you turn all of your organs into mana reserves.''

''...Won't it be dangerous?''

''Are you forgetting that this is a false world? You won't die even if I fail. And most of all, I have done it before.''

''Did it really work?''

''Yes, I did it for a human girl I hooked up with a few hundred years ago. She died of old age though.''

The story has been stolen; if detected on Amazon, report the violation.

''What, did she threaten you with a child between you and her?''

''Pfft- Nope. I always use condoms whenever I do it, I will definitely not be using them with you though, of course. I just did it as an experiment. The girl wasn't very talented anyway, so she wasn't able to power up that much.''

''...What's your body count, by the way?''

''I didn't count.''

''...''

''What, are you jealous? That's cute.''

''I'm not.''

''Don't worry, now that I've found my ideal woman, I won't bother with any other girl.''

''...That's... A good thing, I suppose.''

So basically, my heart will be turned into a dragon's. For your information, I called Eva to ask for an opinion, and she said it was fine—probably, she added.

''First step, strip.'' Sariel looks at me with her usual elegant smile.

''...You're not just going to try and fuck me here, right?''

''I won't, my lust is satisfied, for now.'' She shrugs.

I mean, I did allow her to use my boobs yesterday, and she did cum quite a lot...

So I slowly take off my shirt and shorts, leaving only my panty on. Yes, I'm not wearing a bra, so what?

Sariel nods in satisfaction as she puts her hand on my left breast, her palm sinking into my funbag.

She then closes her eyes and begins to chant, a silver aura surrounds her body, and her two-tone hair flutters.

''!!''

From the center of my heart, a brilliant formula made from Sariel's silver mana, so advanced that even I—an Archmage, is struggling to fathom, bursts out.

A completely alien feeling envelops my body as mana begins to seep inside my flesh, into my bones and organs.

''Sylvia, concentrate all the mana to your heart.''

''On it.''

I take a deep breath and begin to gather the energy flowing inside and outside my body into my beating heart.

''Phew...''

And not to brag, but with my excellent mana control, my heart is already filled with mana after only a minute. This... Feels quite... Warm, and dense, like semen.

''Not yet. Pull more mana from your gems.''

''O... Kay.''

So I pull out mana from my earrings and necklace, letting them flow into my heart. The clump of mana is getting thicker and thicker, and my breath begins to get a little rough.

''Not enough, pull more.''

''...Hgn...''

This is a bit draining... It's similar to how you would feel after a long cardio session.

Bear it. It's all for bigger explosions...!

''You're doing good. Halfway there.''

''Ugh...!''

This is only half of it?!

My lung and heart is burning...!

''Endure it, Sylvia. For a future filled with explosions! Set your heart on fire!''

Set my heart on fire!!

So I endure and endure it, for another five estimated minutes that feel like an eternity.

''Now, Sylvia, create pathways from your heart to outside. Follow the blood vessels.''

Fuck! But that makes sense... I need to get mana out of my heart to use magic.

''Hgn...!''

''I'll reward you after this, keep it up.''

I'm trying...!

So I spend another five estimated minutes trying to make roads from my heart to outside—my fingertips, my toes, trying to make them spread inside my entire body. It is hella hard to maintain the shape of the mana vessels and keep the dense energy inside my heart at the same time.

It's almost done...!!

''Ugnh...! Hah!''

I collapse into Sariel's embrace, completely out of my breath.

''Good job, Sylvia.'' Sariel says with a gentle voice, stroking my head.

This is fucking amazing... It's the first time I have mana stored inside my body, I feel like I can take the world with this...

The only downside is... This ain't my real body, so I'll have to do it again later...

''As promised, it's time for your reward.''

''...Ah, there was that too...''

I suspect she'll whip out her giant cock and fuck me with it, which I'll have to turn down-

''Here.''

To my surprise, she pulls out a large cylinder and hovers it before my face. The cylinder is roughly the size of a cup, and it is filled with a cloudy and greyish liquid.

gulp

''...''

That looks delicious...

''Do you want to inject it into your womb? Or-''

''I'll just drink it.''

I take the cylinder from her hand and put the tip into my mouth, then slowly push the semen out. The thick and gooey liquid fills my mouth, accompanied by the signature fishy smell that I've come to love now.

The sweet flavor and the thick texture of it stimulate my taste bud as I gulp down this absolutely delightful cum. My stamina rapidly recovers, and I can even feel my mana control getting a bit smoother.

''Hah...'' I put down the empty cylinder.

There's no more...

''Your face is unbearably lewd right now, you know that?''

Sariel caresses my cheeks, smiling softly.

Suddenly, she lowers her head and plants a kiss on my forehead.

chut—!

''So lovely.''
