"Pandora, is it gonna be much longer?" Azraelith asks me as we lie in the castle garden, soaking up stellar radiation directly onto our bodies. The castle is currently "parked" near a star.

My body is sprawled out on a massive chair, arms open wide, while the black spiral above my neck absorbs the light, and the giant eye rests on a soft cushion.

"Big Sis, not now, please... I’m resting. It’s still gonna take a while. No rush. If we go too fast, the castle will break apart," I say, bored. 𝒇𝓻𝓮𝓮𝙬𝙚𝒃𝒏𝓸𝙫𝒆𝙡.𝓬𝓸𝒎

"You stopped the castle just to bask in starlight. You can’t exactly demand I stay quiet."

"Why don’t you take in some light with me? The weather’s wonderful." Frustrated, Azraelith climbs onto my body and stands on my belly. It’s kind of cute because she looks so small compared to my size.

"Weren’t we supposed to get there as soon as possible? Are you being lazy again?"

"No, and spare me another lecture. I’m taking my goals seriously. So much so, this is me working on them. I realized I can use the Primordial Goddess’s Mana as fuel to level up." I figured that out when I devoured the abyss.

"That’s why I’ve been searching the universe for things that contain her Mana to absorb. And, lucky for me, I discovered that large celestial bodies hold her magic—or rather, super-condensed stars that should have collapsed but didn’t."

"They’re stable because they possess a certain amount of direct Mana from the Primordial Goddess. Often, the Mana is already ’rotten,’ but it’s still usable! Meaning, I’m absorbing this to try and increase my level." As I say this, Azraelith sits down on my belly.

"You discover the craziest things about our universe. So, does this star here have what you’re looking for?"

"Yes, but it’s a small amount. Still, later on, I’ll create millions of tiny avatars and let them roam the universe in search of stars I can devour to raise my level."

"I’m so jealous... I’d love to be able to level up just by eating things." She rolls her eyes at me with a playful tone.

’It wouldn’t be possible.’ I can only do this precisely because of my passive skill, [Devourer]. That passive, which I was born with, surprisingly enough, turned out to be one of the most incredible things I was given, alongside [Essence of Creation].

Beyond that, I’ve been giving serious thought to omnipotence. If the Primordial Goddess wants me to become omnipotent and take her place, then logically, wouldn’t I need to increase my power to her level? That would be impossible.

What would work is absorbing her power into my body, growing with it until I achieve omnipotence. And since my sister strengthened my resolve, I will try to become omnipotent—even though it’s a secondary goal, not my true focus.

After all, the odds are incredibly low, and I don’t even know if the Primordial Goddess actually wants that. She wasn’t specific and was far too neutral on the matter.

"Wow... your skin is so soft." She touches my belly.

"It’s a texture alteration. I changed the texture of my skin to absorb the star’s light more efficiently." As she rubs her hand across my stomach, the mouth opens, tongue lolling out.

She grabs the tongue from my belly mouth, touching the teeth curiously. I ignore her prodding, just continuing to absorb the Mana held in the star’s core. Unfortunately, it’s a meager amount, but little by little, I’ll reach level 100 billion.

"You know, your teeth are bizarre," Azraelith says out of nowhere, touching the base of the fangs.

"Why do you say that? Our teeth are the same shape—sharp and made for tearing and crushing flesh." That’s the jaw structure of our race, designed for powerful, ripping bites, tearing meat and grinding it up along with the bones.

"I mean their durability. I don’t quite understand how your passive works, but a knife made from your teeth would be insanely strong. It would only be weaker than a Special Grade Weapon or a Divine Weapon."

"...Do you want to go inside my mouth?" I ask teasingly as she pulls on the tongue, stroking it.

"No, I wouldn’t dare. What if you actually tried to devour me? I’m just interested in your true form. You seem much stronger using it than your normal one."

"Isn’t that the whole point?" I ask, confused.

"Theoretically, yes. But my true form is weaker than my humanoid form. And Mother’s true form is also less efficient than her humanoid one since she gets too bestial in it and loses a lot of control."

"You’re the only one who came out ahead. Though that’s the fault of adaptation. I adapted so that my humanoid body would have more advantages, which weakened my true form."

"...Can I see it?" I ask, curious about her true form. She stares at the giant eye resting on the cushion and then sighs.

"I’ll show you. But don’t mock me." She jumps off me and onto the ground. I sit up to watch her body shift and grow until the transformation is complete, and I’m taken aback. It’s a beautiful appearance, but very unique.

A giant humanoid, nine meters tall, with extremely white skin that has a slightly translucent quality, allowing a glimpse of black blood coursing through her veins. Her hair is incredibly long, cascading down to the floor. Her body has no face—no eyes, nose, or mouth. The absence of a face is strange and gives her beauty an almost alien aura.

Her body is extremely voluptuous, almost seductive, but she has a large eye where her navel should be. Her legs are completely black, and as it reaches about mid-thigh, the blackness turns into a cracked pattern rising up to where her thighs connect to her hips.

Her hands share the same pattern: completely black up to the elbow, with the cracked pattern climbing from the elbow to the middle of her upper arm.

And on her neck, there’s a black mark like a collar adorned with several diamond shapes, resembling an elegant choker. Overall, a beautiful appearance, but also frightening.

Above her head floats a giant halo emitting a lovely, almost angelic golden glow. Her tail has completely changed shape, becoming extremely thin like a succubus’s tail, but the tip forms an elongated diamond structure, like a kind of spear.

"Wow... your form is so... magnificent. You’re gorgeous," I tell her as she sits down on my thighs. Her faceless visage facing the spiral that replaces my head is a bit strange.

"Magnificent? I honestly think I look ugly in this form. It’s weird, and it follows a very... unique pattern. It focuses way too much on magical power, which breaks my fighting style that relies on explosive, highly destructive attacks." As she speaks, I just stare at her large breasts.

’Fuck...’ My arms start to rub against each other until they bleed, while Azraelith distractedly lists the things she dislikes about this magnificent, beautiful form.

"Haaa..." I gasp, mesmerized. My body grows hot as, for the first time, something sexually attracts this form. Ever since I transformed into my true form...

Nothing had turned me on sexually. No matter the beauty presented to this appearance, sexuality was hardly appealing. So I thought I had lost any desire for sex in this form—which was strange, considering monsters are more bestial and instinct-driven.

But the issue wasn’t that the girls were ugly; they simply didn’t match the visual pattern that attracted my monstrous body.

"H-Hey, what are you doing!?" Azraelith shouts as I pin her to the ground. Her voice is somewhat distorted and echoes from all directions, the same effect as mine. The mouth on my belly is practically drooling, saliva dripping onto her stomach.

"Adorable... I love you... You’re so beautiful. The most beautiful. The loveliest thing I’ve ever seen." The giant eye floating behind my head turns a solid pink in the pupil—an effect I didn’t even know could happen.

Apparently, when something is sexually attractive to me, my eye reflects it. Probably because of my passive ability to see emotions. And right now, I’m crazy with lust and love for this adorable Big Sis, so the pink in my pupil makes sense.

"Please, stay still! I’ll be quick!!!" I lose all control, pinning her against the ground as she tries to push me away.

"W-What the hell! Where did all this strength come from!? Hey!! Hey!! Let go!! PANDORAAAAA!!"

...

...

...

"Echidna, are you hearing a weird noise?" Evangeline asks me, confused, as we listen to booming sounds, like something huge slamming against the ground.

"I’ll go see what it is. Stay here," I tell Evangeline, who just nods. Because Pandora stopped the castle near a star, Evangeline has to stay inside for safety.

"Are those two training?" I noticed a lot of magic leaking out, so I soon look out the window from the room, and what I see catches me completely off guard.

My two daughters, in their true forms, fucking like a pair of wild animals. Or rather, specifically, Pandora is fucking Azraelith, who doesn’t seem to have much room to maneuver.

"Okay... that’s... fucking weird to watch. Is that actually a position you can use for sex?" They’re twisted into such a contorted... so, so contorted shape that I’m confused whether something sexual is actually happening or if they’re just trying to kill each other with some weird chokehold.

’Pandora’s arm is twisted so much I think it’s broken. How did she do that?’ I stroke my chin for a moment, truly fascinated.

Pandora is somehow simultaneously being penetrated by Azraelith’s tail, licking Azraelith’s pussy with the mouth on her belly, touching Azraelith’s anus with two of her hands, and pressing the black spiral floating above her head against Azraelith’s face.

All while maneuvering her own pussy close to Azraelith’s hand so she can reach it. It’s like trying to watch two snakes intertwining, only much more bizarre.

’Well, they’re two monsters. I suppose it couldn’t be any different...’ Pandora’s giant eye looks in my direction, the pupil completely pink and dripping some kind of clear fluid onto the ground.

And the loud sound I heard earlier is just the two of them rolling around on the ground like a ball. I simply turn around and leave, not wanting to interrupt their strange situation.

’I don’t know whether to be happy that they’re getting along so well or disturbed that Pandora has so little self-control she fucks in the weirdest way I’ve ever seen.’ I pull out a special book where I take notes.

"Well, at least that answers my questions." I quickly jot down the behavior I witnessed in the book. It’s a personal journal I use to write down patterns of Pandora’s race.

I briefly write about the interaction and behavior, and I make sketches of the position the two were in. With that, I catalog how the monstrous forms of the two handle carnal relations.

’I think this is the fault of the tentacle monster biological base.’ Tentacle monsters writhe and coil around each other. Since I based their regeneration on that type, it seems they also picked up the active behavior patterns.

But now that I’ve made my notes, I head back to take care of my dear sister, completely ignoring the sounds coming from the two of them.
