Confirmed — A Degenerate Womb, Reserved for the Demon
I let out a light yawn — haaah — and opened my eyes. The women who had been plastered to either side of me were gone without a trace.
Like some midsummer dream?
Mm... so they'd just up and left, then. Well, fair enough. No matter how you sliced it, shoving my cock in once wasn't going to flip them in a single night...
"Oh? Lord Marbas is awake!"
"Hehe... shall we start, then, Yume?"
"Yeah! Nelly!"
Their voices came out of nowhere, just like that.
It was morning, and my head was still swimming. By the time I'd barely pulled myself together, what had popped into view was quite the spectacle.

"Nnnyoh— a cheer dance, first thing in the morning, for a cock that's already standing at attention!"
"Ohot— ohot— bounce, bounce— stare at these tits all you want and get that dick as hard as you please!"
Hands clasped behind their backs, legs spread wide, pussies bared for all to see — the two of them had launched straight into a female dance, and the whole display was planted square in front of my face.
"Whoa... what the hell are you two doing."
I asked because I genuinely couldn't believe my eyes, and the answers they spat back were just as absurd.
"Praising a cock that's been rock-hard since morning is only natural for a female onahole!"
"Hehe... honestly, you already know perfectly well how lewd we are. Using these female bodies — the kind that get a dick standing straight up — to dance a pussy dance from the crack of dawn, purely for the sake of an erection? Isn't that just common sense?"
Good grief. They'd fallen so completely for my cock that they were spouting nonsense that didn't even hold together. All it really meant was that they wanted to do this, so they were making excuses and performing a degenerate little dance right in front of me.
"What do you think you're doing! You two started shaking those useless pussy dances first thing in the morning, and now my cock feels like it's about to shoot straight up into the sky!"
With that, I strode right up in front of them and shoved my erection forward.
The moment the cock brushed her lower belly, Nelly let out a heated breath — hooh — and looked up at me with eyes that were pounding.
"Ah, aah... your cock's tapping, tap-tap, against my baby room... a throbbing, trembling cock is the best—♥"
"You've got a body this soft and female, and you're telling me you were a virgin until now? That's ridiculous!"
"Ah... haah... hiiit..."
With that throbbing cock pressed against her, she could only stare down at her lower half, eyes shaking like mad.
Watching Nelly like that, the answer I gave her was simple.
"Apologize with that pussy of yours!"
"Eh... w-wait, nnghooooh—♥"

And just like that — zut-kyung—♥ — I drove my cock straight into the pussy of Nelly, who was still mid degenerate pussy-dance.
A light snap of my hips, and I slammed in without mercy on the girl already going hogok, hogok. Then I pounded her pussy with my dick as hard as I could — pang, pang — and she threw her head back with a sweet, thick breath, nnnyoh. The sight of it was truly something else.
"Apologize by serving this cock! As penance, take this fresh, piping-hot load I just made this morning into that pussy, and dance your bounce-bounce pussy dance!"
"Yes—! I understaaand—! I'll take every drop of cum into my pussy with everything I've got! So please, dump all the cock-juice you want into my pussy—!"
She was shaking those tits — bounce, bounce — and screaming insane things. How was I supposed to do anything but grant her wish?
"Fine. Take it, you little bitch!!!!!"
"Nnnyoooooh—"
Byururururut—
Dokyut— dokyut—
With a thick, wet sound, I poured a fresh morning load — gulleong, gulleong — straight into the baby room of Nelly, who had thrown her head back with a hoooh.
Panting ohot, ohot, she sent me a glazed, sweet look, then started rolling her hips in little circles, laying the aegyo on for good measure.
"Aaaah... to cum in my pussy this hard, first thing in the morning. As expected of Lord Marbas... a merciless creampie feels so gooood...♥"
Well, of course she was acting like that — she was biting down on my cock with her pussy, jjot, jjot!
"Don't pull aegyo when all you know how to do is gulp down cock-juice, you female!"
"Nyeheet— I'm a female tissue you can dump cum into whenever you want— I'll keep acting cute with my pussy from now on, too~♥"
Zzubbot—
Zzubong—♥
After she'd spent a long while squirming with my cock buried inside her, it finally slipped free of her pussy.
"Hooh... hoooh— with all that morning sperm packed into my pussy~♥ I'll start a sperm-mixing dance in my baby room, nice and hard—♥"
Bounce, bounce — she said it while snapping her hips with everything she had, and the words coming out of her were absurd.
"Cooock—♥ Cooock—♥"
Wow. Her head was completely full of dick, wasn't it.
"Haah... haaah... g-getting fucked by Lord Marbas and taking morning cum in my pussy... Nelly, you cheater!"
"Hmph— he shot that fresh sperm into my pussy because I turned him on more! If you're salty, Yume, then you get him harder!"
"Nnn— no! I want him to cum in my pussy too!"
"Fine! You're next, Yume!"
"Eh? Nnghooooh—"

Zut-kyuung — I yanked my cock out of Nelly's pussy and docked it straight into Yume!
She let out a thick, sweet breath — nyohoooh — and threw her head back, and the sight was honestly pretty funny.
"Ohot— ohot—"
"Nnghiit— cock, the beeest—"
And so I just sat there in the chair, watching the two of them roll their hips in slow circles while they danced a cum-shaking dance inside their baby rooms.
They'd just taken a creampie that enthusiastically, and here they were still snapping their hips with that much energy. Honestly, it was ridiculous.
"Good. Excellent! At this rate, anyone looking would call the pregnancy confirmed, wouldn't they?"
"P-pregnant... having Lord Marbas's cute baby...♥"
"Ah— ah—♥ I'm an exorcist, I shouldn't be having a demon's child—♥"
"But you two know, right? A demon's cum doesn't knock you up the second it goes into a pussy."
"What?"
At that, the two of them tilted their heads. They must have been wondering what on earth I was talking about.
"To put it more precisely, you get pregnant the moment I want you to. My Semen Control runs a little strong, you see."
"What kind of bullshit is that?"
It must have sounded pretty unbelievable. But it was the truth. A demon is, at root, a living thing made of magic that crawled up out of Hell.
In short, it means I can control even the sperm swimming in my semen.
"Ooh— don't believe me? Then shall I show you right now?"
Saying so, I lifted a hand. A snap of my fingers — tak — and they began to tremble all over, a sharp little hit running through them.
"S-something's weird... the cum that went into my baby room feels like it's shaking."
"Lord Marbas? What did you just do?"
"Ah, simple."
I smiled, cocked my head, and tossed out a single line.

"Eh...? E-eh, w-wait... something in my womb is throbbing, kyung-kyung, like— nnghoooooooh—♥♥♥♥♥♥♥♥♥♥♥"
"Nooo— climaxing this pathetically while I get pregnant, just like Yume, is— ohoooooooh—♥♥♥♥♥♥♥♥♥♥♥"
Pyushuuuut— kyut-kyut— pyushuut—
They poured out fluids like mad, squirting pussy-juice from their cunts.
And in the middle of that pussy climax, the cum stored in their wombs began to eat into their baby rooms.
Kyut-kyut — love-juice sprayed in every direction as the two of them started climaxing like lunatics.
The wombs holding that semen changed in an instant — rewritten into wombs optimized to carry a demon's child.
"Hoooooh—♥"
"Nnghhiiit—♥ My pussy's cumming—♥ Turning into a demon womb at the exact same moment as Yume—♥"
"Nyohooooh—♥ I really got a demon's baby—♥ Ohot— ohohot— nnghoooh—♥♥♥♥♥"
Kyut-kyut — who knew how much fluid they'd squirted.
The two of them, heads thrown back, finally let out heated breaths — haaah — and turned their faces forward.
Then they sank down onto the bed, spread their pussies wide in front of me, and went on like this.

"Nnghii...♥ Demon-exclusive womb, confirmed—♥ Now I've become a bitch-pussy that can't even climax unless it's Lord Marbas's cock...♥"
"Haah— hot— hot—♥ He even carved a female crest into me. Like this, I'll be a pussy that can't do anything unless it's Lord Marbas's cock...♥ I wanted Ken's child, but now a demon lord's baby is so much better—♥"
Panting, the two of them pressed their branded slits together and let out nothing but heated breaths, showing off pussies still holding my semen — semen that wasn't coming back out.
"Good. Fine female wombs, the both of you. You can't even cheat anymore. Wear that lewd brand, and you can't get pregnant from anything but my cock."
"Ah... that's actually kind of nice."
"Not getting pregnant off a cock like Ken's is a reward, isn't it~♥"
They giggled — hihit — and cut down the man who had once been their lover without a shred of mercy. Anyone looking could tell they'd fallen.
"Well, fine. It's not like I have no intention of taking responsibility, and I'm not planning to hit it and quit it either. Your pussies have already been made demon-exclusive. Casting you out now would be too cruel."
"Aah...♥"
"Whaaat— gentle, for a demon—♥"
How to put it. The truth was less gentleness than self-preservation. Throw these two out, and they might just cut my head off.
Either way, it was a fact that even their wombs had been made exclusively for a demon.
"Ah, you know that, right? The brand reaches all the way to your clitoris. You've gotten insanely sensitive."
"Eh...?"
At that sudden line, I set a finger on each of their startled clits and flicked — tok.
"Nnghooooh—♥♥♥♥♥♥"
"Nnghhiiit—♥♥♥♥♥♥"
And just like that, both of them threw their heads back at the same time, squirting love-juice — kyut-kyut — from their pussies as they climaxed.
"Ooh— nnghooh— getting my pussy to cum from one little flick on the clit is the beeest~♥"
"If it weren't for you, Demon Lord, I never would've known I could do this— thaaank youuu—"
They'd become bodies that came from a single flick to the clit, and they were thanking me for it! Wasn't that way too perverted?!
