Dungeon Overlord: Monster Girl Harem!

Erina's hand hovered in the air, reaching for the beautiful core which shimmered in her sight.

'If I accept this now, can I become powerful?'

The desire to change, to face Leonhardt face-to-face without feeling inferior, flooded her mind as she brushed against the smooth surface. "Ah?" The core throbbed... as if it were alive, beating like a heart.

'Can I fight like Asuka or Sylvie?'

That was what she wanted...

'To become like Zafira, a powerful woman!'

Her heart beat louder, faster as her mind began to fill with a deep sense of desire.

However, she still held doubts: would this be the right choice, and would she regret it after it was too late? Erina knew that Leonhardt enjoyed the process of breaking and bringing people to his side.

'If I choose to take this, will he abandon me?'

It was her deepest fear.

Exactly when it became her fear, she didn't know, 'I used to want to escape and run away from him.'

Erina remembered how happy Zafira seemed, being broken by him into submission. Yet, she feared becoming nothing but a slave... the same as Dia, who remained chained in the dungeon alone.

'I don't want that.'

Zafira didn't rush Erina, only watching the young woman struggle with the decision... even though she knew this wasn't what Leonhardt wanted, there was something about this girl that tickled her instinct. She believed that Erina might be a good sister, and thus... she made her move. "He isn't here, Sister."

A whisper, almost inaudible.

Erina's hand gripped it and pulled the core to her bosom. "I will become more powerful if I have to do it by myself!"

Her green eyes became clearer, like a forest of emeralds...

"Swallow it."

Zafira smiled as she stood back, turning towards the Orcs who were approaching after the massive commotion they had caused.

"Come, foul pigs! Let me show you the powers of a demoness princess!"

There was no need for them to prolong the battle; the Orcs had lost their leaders and now staged a desperate attack, but...

Zafira didn't plan to allow any of them to remain alive, not after her declaration of war. Her wings spread, shrouding her in a black mist that grew larger and larger until it completely covered her figure, and she flew towards the broken wall.

"Sylvie did her best too..."

'When did I grow attached to these other women?'

The changes in the dungeon weren't limited to the goblins who started learning human language, starting their businesses, but also Zafira herself.

The difference was so vast that it shocked her as she flew through the sky.

"A world where even a goblin can succeed... How interesting."

***

Erina's face turned blue at the disgusting thought of putting a monster core inside her mouth.

'How do they eat this?!'

With trembling lips, she put the core to her lips, pressing it against her mouth and slowly parting them as the succubi princess suggested. It entered her mouth with a cold tingle. The taste reminded her of warm blackcurrant tea and liquorice blended, with a hint of metal. She bit down on the core, and the moment the juice touched her tongue, a cool sensation spread throughout her body, followed by an all-consuming heat.

'Delicious...'

The soft centre was like pudding, melting on her tongue before sliding down her throat.

As it passed through her body, she didn't feel anything different; her body rolled onto her back, and she started taking breaths, wondering when it would happen.

'What's going to change?'

She was curious, but nothing happened.

'...Where is that overwhelming power?'

Erina felt cheated. Her chest hurt.

The desire for power consumed her, making her crave it like an addict craving its poison.

But the moment she started to doubt, it hit her like a club to the womb...

Maybe because it was a succubus core... the heat didn't start in her chest or stomach but her womb, a burning pleasure that sent her mind into a frenzy.

"Ahhh!" Erina's body arched off the ground as her crotch burned with an unbearable pain.

It felt like someone was trying to pull her ovaries and womb out of her body, which made her scream uncontrollably into the air.

"Make it stop! Make it st-"

The plea stopped midway through the sentence as a new sensation spread through her body: a warm bliss that spread from her spine to the rest of her body, dulling the pain in her chest.

"Ack!?"

Her hips quivered as the feeling of something squirming under her flesh... near her buttocks, a slight pain grew before something emerged... The pain increased, as something started tearing her skin, yet the moment it broke free, Erina only felt pleasure.

A black tail with a heart-shaped tip sprouted from her backside.

The heat subsided slightly, but it didn't last long. More of the same pain emerged this time in several places...

Her buttocks ached with a dull heat...

As if Leonhardt was squeezing and kneading her cheeks, the memories of how he touched her body flowed through her mind.

Next... her breasts, a painful feeling as if being pinched, stretched out and pulled on... her body burned as she rolled around on the grass. Her face was filled with dirt.

Erina panted like a bitch in heat.

Her mind became foggy... the world grew distant, her surroundings blurred.

'What's happening?'

She could swear that Leonhardt's voice echoed in her mind, asking her questions... ordering her to do obscene actions while squatting between his legs.

The bones in her hips and pelvis cracked as they shifted, her spine elongating, adjusting to her new height and tail. The flesh swelled and pulsed with a wave of pleasure that left Erina quivering and moaning on the floor.

"It's too hot..."

Erina's clothes burned on her skin, and the touch of the wind became unbearable as her body transformed. It felt like a passionate kiss on the tip of her clitoris, yet all her body endured this sensitivity.

'Is this Zafira's world!?'

The heat... the overwhelming need to feel loved, cherished... and fucked, to drown in pleasure, made Erina clench her legs with desire, even her nipples hardened as she groped at them... her fingertips now claws covered in a black exoskeleton... her head felt heavy as two long curved horns trapped the ground each time she flung her head back.

The tips of her ears shifted into sharp points, her skin became smoother and paler, almost transparent... like a delicate artwork.

"Phew..."

The pink mist faded, revealing her completely transformed figure...

A throbbing energy of golden light hissed across the air.

It wasn't mana but something far more potent and denser... holy energy.

'This is it... the gift I wanted...'

Erina stood on trembling, weak legs and looked down at the destroyed clothes she wore.

Her clothes were too small, squeezing her breasts and hips painfully.

The same black armour that covered her claws was now covering her forearms and lower legs, like boots. The chitin-like armour was flexible and soft to the touch, yet it could stop many blades.

"Ah!" Erina bit her lip as her mind cleared for the first time since swallowing the core.

Her stomach was tight... the faint abs now more defined and a small tattoo spread across her pelvis... a golden succubus marking, with a name already etched into the heart.

"What!?"

Erina exclaimed as she noticed the writing and read it, a strange tingle in her chest.

'It already says Property of Leonhardt Van Arlet?'

Erina smiled, then gently touched the tattoo.

A pleasant feeling... far from sexual, it was more like a connection or bond.

Her body was no longer trembling; her legs felt firm and decisive, her chest... "My boobs are bigger..." She cupped them while squeezing the tips, only to gasp because a milky substance leaked from the tips. "Hmmm? It smells sweet, is this milk!?"

She licked it off her claw.

'Delicious...'

A sense of shame filled her mind, 'What is this? How can I be so embarrassing?'

Her new form was strange and alien to Erina.

Even her tail seemed to have a mind of its own, wriggling around as if trying to catch her attention.

However, she also felt a sense of freedom...

"Does it feel good?" A sudden voice came from behind, but Erina no longer felt a sense of danger or fear from the voice; instead, it was comfortable and familiar.

"Sister Zafira? I don't know yet, it's all too sudden."

"I see, but to think you retained your hair and eyes, that's some amazing willpower."

Zafira's praise made Erina's lips curl.

"I want to go back... to show him..."

The demoness princess snorted in amusement. 'That is the first thing she thinks about... she wants his attention and validation.' She could only imagine how jealous Leonhardt would be, but at the same time, looking at the blonde, Zafira felt a sense of rivalry. 'She's still young, but I feel she might become my rival...'

Zafira's eyes lowered to the information popping up on the dungeon panel.

What she saw only made her envious.
