My Wives are Beautiful Demons

[A few hours before the Underworld was invaded...]

Arriving at Sapphire's mansion in the human world, Vergil walked with firm, silent steps to the front door. The air around him seemed to weigh a little heavier with each step - as if even the world sensed that he had changed.

As soon as he opened the door, he was greeted by his two maids, Iridia and Zex, both wearing classic maid's dresses similar to Viviane's - elegant but discreet.

"Welcome back, Master..."

But their voices faltered at the end. As they looked up at Vergil's face, they were suddenly stunned. Their eyes widened. Their hearts raced.

'He... he's absolutely stunning?!' - they both thought in unison, almost without realizing it.

It wasn't just an ordinary change. With the new vibrant purple hue in his eyes and his hair darkened to absolute black, Vergil seemed sculpted by some superior force - a refined, dark and overwhelming version of himself. It was like looking at the very definition of ideal masculinity... and something more.

A dark charm that made them both feel... strangely vulnerable.

"..." Vergil just nodded, with a small, enigmatic smile. "Well done, my dear maids."

The words were soft... but charged with a magnetic aura.

The maids shuddered, awakening from their trance as if they had been pulled out of a spell. Their cheeks flushed slightly, their eyes gasped, and an automatic smile formed on their lips.

But soon his tone changed - and with it, the whole atmosphere seemed to harden.

"Viviane." He spoke, seriously. "Where is she?"

Zex was the first to react, swallowing dryly. "She's on the second floor, with Miss Kaguya..."

Vergil narrowed his eyes.

"Did something happen?"

"...Yes, Master." Iridia replied, more hesitantly. "It seems she's entered some kind of... vampire stage that we still don't understand. It was sudden."

She bowed her head slightly, embarrassed. "I cut my finger, by accident... and she attacked me. Instinctively. She couldn't control herself. We managed to restrain her... but only because we're trained to deal with demons."

The silence that followed was piercing.

Vergil merely nodded, his jaw tense. His eyes flashed for a second, and the shadow of genuine irritation crossed his face.

He took a deep breath, keeping his face impassive. But inside...

'What the hell is going on now?

All he wanted was a simple extraction mission. To pick Viviane up and take her back to the Underworld - quickly, cleanly, without incident. According to Morgana, Viviane knew the Witch Queen. Having someone with that kind of connection could be extremely useful... if she wasn't in the middle of an outbreak.

With a slight pop of his shoulders, Vergil started up the stairs. The sound of his footsteps echoed through the silent mansion, each step adding to the weight of strangeness in the air.

He approached the ajar door of the room where Iridia had said Viviane was. The energy there was... strange. Something pulsed on the other side, between the supernatural and the frankly uncomfortable.

Vergil pushed open the door.

What he saw... made him stop.

Kaguya was hanging by red ropes from the ceiling, in a meticulously tied pattern - similar to a shibari practice, but adapted for the supernatural context. She was gasping, her eyes glowing bright red. Her canines had grown so long that they had pierced the corner of her own lips. A thin trickle of blood ran from her mouth, as if she had been on edge for hours.

It was... a disturbing scene.

And there, calmly sitting in an armchair near the window, with her legs crossed, was Viviane. Her eyes were completely focused on the book in her hands - which, as she approached, Vergil saw was a thick copy with gold lettering: "Mastery and Deliverance: A Mystical Guide to Playing with Your Husband."

She elegantly turned a page. She seemed immersed.

"..." Vergil watched the scene for a while in complete silence.

Finally, he sniffed and said, his voice dry and emotionless:

"When, exactly, did you get so perverted like that?"

Viviane didn't even look at him right away. She marked the page with a red satin marker, closed the book carefully and only then looked up.

"Hi darling," she said with a calm smile, "you took your time. I was already at the part where they teach you how to use magic candle wax."

Vergil stared for a few more seconds, then turned his eyes back to Kaguya - who was now gasping and growling softly like a caged animal.

"...Did she consent to this?" he asked, without changing his tone.

"She asked me to tie her up," Viviane replied casually. "She said she was going through withdrawal and didn't want to hurt anyone. I just... got creative."

"Creative." Vergil repeated, as if the word were a sentence.

"M-me of blood..." Kaguya moaned between the restraints. Vegil didn't know if it was because of her abstinence from blood or because of the ropes, which were positioned in very arousing places.

Vergil wiped his hands across his face, taking one last deep breath before looking at Viviane again.

"I've got problems," he ordered in a firm voice. "Wait for me downstairs please, we need to talk."

Viviane raised an eyebrow, but didn't argue. She just held the book carefully, smoothed her hair and replied with a teasing smile:

"It's all right, darling. I won't do it anymore, there's no need to get so serious."

She turned and left the room with elegant steps, leaving the sound of her heels echoing in the corridor.

As soon as she was out of sight, Vergil let out a long sigh... and turned back to the scene worthy of a comic nightmare in front of him.

Kaguya was still suspended, dangling from the ropes like a mystical Halloween ornament, eyes glowing with thirst and a half-animalistic moan escaping her wounded lips.

"M-master... blood... with strength, if you can..."

"Good heavens..." Vergil muttered, as if he were trying to convince himself that it was real. "Lilith, my grandmother, why have you been tantalizing my thoughts like this? Throwing hot women at me in delicate situations like this. What have I done to you, Grandma?"

With a quick, precise movement of his hand, he conjured a blade of purple energy and cut all the ropes at once.

Fwsh!

Kaguya fell... straight into his arms.

"Ahhhn~! Grab my neck, tame me-"

"Shut up."

He held her with one hand, while she wriggled in his arms like a cat addicted to catnip and noble blood. Her legs wrapped around his waist with frightening naturalness.

"Are you having a withdrawal crisis or staging some gothic castle porn?" he growled, irritated.

"Why not both?" she gasped, her eyes watering with desire... and thirst.

Vergil just sighed as he walked over to the nearest bed. He unceremoniously dumped Kaguya on the mattress like someone dropping a hysterical backpack after a tiring day.

Thump!

She fell with a muffled groan, sinking into the sheets while still writhing between agony and... something else less urgent.

With a snap of her fingers, several small purple blades floated around her - precise, sharp little knives, lethal and delicate at the same time. Like metallic petals in mid-air.

Clink-clink-clink!

Within seconds, the ropes that still bound parts of the vampire's body were severed with surgical perfection. Her arms fell free, her legs too, and her body stretched out like a cat coming out of its stupor.

Kaguya's skin was covered in purple and red marks, the result of prolonged pressure and perhaps... an exaggerated desire for drama.

Vergil crossed his arms, assessing the scene with half-closed eyes.

"Well... at least Viviane only tied you up. If she'd done anything else... then I'd be really angry."

His tone was so calm that it sounded like he was commenting on the weather. But the faint, menacing glint in his eyes made it clear that he wasn't joking.

Kaguya looked down at him, still gasping, her face too flushed for someone who was just thirsty. Her red eyes looked drunk.

Then Vergil stepped forward.

And began to unbutton his own shirt.

First button. Then the second.

Kaguya shivered. Literally. Her body tensed, as if an electric wave had gone up her spine.

She held her breath as he opened his collar, revealing part of his neck - the pale, strong skin marked only by thin traces of veins.

Then he stopped in front of her.

His eyes glowed purple, intense and imposing. And with a subtle gesture, he tilted his neck to the side, offering it to her.

"That's what you wanted." He said, in a low, authoritative tone. "Drink."

It was like flipping a switch.

Kaguya's body shuddered, her pupils dilating to almost black. A second later, she had already jumped on him - her thighs wrapping around Vergil's waist with animalistic force, her arms embracing him like a trap, her lips opening with a slight tremor.

CHOMP!

She bared her teeth with brutality and pleasure. Blood touched her tongue and a moan escaped her throat, full of relief and ecstasy.

Vergil didn't even move. He just took a deep breath and closed his eyes, accepting the pain with stoic serenity.

"...You really are desperate," he murmured, almost to himself, as he felt the warmth of his blood being sucked in greedily. "But you'd better control yourself... or I'll tie you up next time."

Kaguya just moaned against his neck, as if it were an irresistible promise.
