Depraved Noble: Forced To Live The Debaucherous Life Of An Evil Noble!-Chapter 621: Let’s Take A Bath Together

Aqua’s mind spiraled back to what she had once believed was the single most humiliating moment possible in her entire life.

The Archmage Certification Ceremony.

She had been nineteen at that time—young for such a title, but already terrifyingly gifted.

The grand hall of the Arcane Citadel had been packed wall-to-wall with the continent’s most revered mages: gray-bearded archmagi who had reshaped mountains, elven sorceresses older than kingdoms, battle-mages who had survived wars that ended dynasties.

They had all traveled thousands of miles—some crossing oceans of mana storms—just to watch her andjudge her.

Her own teacher stood at the front row, arms folded, expression unreadable.

And in the VIP gallery above them all: her mother, regal and expectant...and the Empress herself, her aunt watching with that cool, imperial smile that could freeze blood.

Every eye had been on her.

She knew that one mistake, one flicker of mana out of alignment and she would have brought shame not just on herself.

But on her bloodline, her teacher, her nation.

She had spent the entire week before convinced that if she failed, she would never recover.

She would become the cautionary tale whispered in every tower: the prodigy who crumbled under pressure.

And yet...she hadn’t.

She had passed flawlessly. Not a single error.

The hall had erupted in polite, thunderous applause and she had walked out an Archmage.

Back then, she had thought nothing could ever surpass that terror.

Now she realized how laughably naive she had been.

Being caught by her own brother—

—naked, on the floor, legs spread, pussy still twitching and dripping from the orgasm she had just had while watching him ass-fuck another woman—

—was infinitely worse.

She wanted to die.

Right here. Right now. Just leap off the nearest balcony and let the fall end it.

Anything, literally anything was better than having to look Cassius in the eye and explain why she had been masturbating to him railing Portia like a beast.

Because of this she thought her life was over.

He was going to hate her.

He was going to look at her with disgust forever.

He would never see her as his big sister again—just some perverted voyeur who got off on watching her little brother have sex.

She was so red she could feel the heat radiating off her face like a furnace. Her heart hammered so hard she thought it might crack ribs.

She braced for the worst.

Scolding. Yelling. Him storming out in embarrassment. Him freezing in horrified silence.

Any of it.

And that was when Cassius moved.

He got out of the pool of water and wrapped a towel around his waist—still visibly hard beneath the fabric and walked straight to her.

Aqua’s breath hitched.

At least he wasn’t running. At least he wasn’t recoiling.

But now he was going to confront her.

Mock her.

Demand answers.

Ask why she was here, why she was wet, why she had been touching herself while watching him.

She squeezed her eyes shut tight.

She couldn’t bear to see revulsion on his face.

But she would just...accept it.

Whatever came. She deserved it.

But no angry words followed.

Instead, something warm and careful touched the outside of her right knee—right where she had banged it on the fall.

Her eyes fluttered open and she was shocked by the sight.

Cassius was crouched beside her, expression soft with worry.

No judgment. No disgust.

Just concern.

"Hey...are you okay?"

His voice was gentle, almost tender.

"Does it hurt here?"

He pressed lightly against the reddened skin.

"Or here?"

Another careful prod.

"It looked like a nasty fall. I hope you didn’t twist anything. The last thing we need is you hobbling around on a crutch your first week back. Or worse—me pushing you in a wheelchair."

"Can you imagine? ’Oh look, there goes the future archmage being wheeled to breakfast by her baby brother.’ You’d never hear the end of it."

A tiny, involuntary laugh escaped her despite everything.

He was...joking.

He was actually making a small, stupid joke while rubbing her knee like she was made of glass.

And seeing this, Aqua thought that maybe Cassius didn’t care about what she did.

That it didn’t bother him at all.

That he had reached a level of depravity, where this sort of thing didn’t affect him one bit.

But then she looked at him closer and realised that was not the truth.

In his eyes—beneath the concern—she could see it.

Confusion. Embarrassment. A faint flush high on his cheekbones.

He knew exactly what he had just walked in on.

He knew she had seen him balls-deep in Portia’s ass.

He knew she had come while watching.

But right now, right this second—he was choosing to ignore all of it.

Pushing it aside.

Because she had fallen.

Because she might be hurt.

Because right now, the only thing that mattered to him was that his big sister had fallen and might be hurt.

Realising this, her heart cracked open.

All the panic, all the shame—it melted under the warmth of how much he cared.

Her terrified eyes softened and turned adoring.

A tiny, trembling smile curved her lips.

"It’s alright, Cassius."

She said quietly, propping herself up until she was sitting properly on the damp floor.

"Really. It’s okay. It sounded worse than it was. Just a little bruise. I can still walk and everything."

Cassius frowned, unconvinced.

"It might seem small now, but sometimes these things get worse later. Look, see how red it is already? We should probably—"

Aqua rolled her eyes playfully, cutting him off.

"Oh, come on. You know how pale my skin is. The tiniest tap turns me bright pink and honestly it looks way worse than it feels."

She pushed herself to her feet—wobbly at first, but steady enough and started walking in circles right in front of him.

"See? Look, Cassius. Big sister is walking. Perfectly fine. No limp. No pain. Happy now?"

She stepped closer until she was standing right over him—still crouched—and reached down to ruffle his damp hair affectionately.

"So, don’t worry so much. I really appreciate it—I do. Big sister loves that you care..."

"...But I’m okay. Promise."

She expected relief from. A sigh. Maybe a sheepish grin.

Instead—silence.

Cassius didn’t move.

He stayed crouched, head tilted back, staring up at her with wide, dazed eyes.

And that was when she realized.

The towel had fallen completely.

She stood over him—utterly naked.

Breasts hovering just above his face, heavy and full, nipples still peaked from earlier.

Soft belly. Long legs.

And directly in front of his eyes—her pussy, flushed, glistening, a slow bead of her release sliding down her inner thigh.

He was staring.

Right at it.

Aqua’s face ignited.

"S-Sorry—sorry, Cassius!" She snatched the towel up in a frantic bundle, clutching it to her chest. "I didn’t—I wasn’t—Cassius, I—"

But the towel was too small.

Her breasts spilled over the top.

Half her ass cheeks peeked out beneath.

The very bottom curve of her pussy remained visible no matter how tightly she pulled.

And so, she stood there—half-covered, mortified—realizing she had ruined everything.

Again.

And again.

He was the perfect little brother—gentle, caring, selfless.

And she was the degenerate older sister who had just masturbated to him fucking someone else, then flashed him her dripping cunt while pretending to comfort him.

She wanted to die or atleast run away from this humiliation ritual.

But running would make it worse.

He had seen the wetness.

He wasn’t a child anymore—he knew exactly what it meant.

He would connect the dots and he would know she had come while watching him.

If she fled now, the silence between them would fester forever.

She had to fix this.

But how in the world was she supposed to fix this?

There was absolutely no excuse she could give for what she’d done or why she’d done it.

No matter how she tried to explain, it would sound ridiculous.

Then it hit her.

She didn’t have to explain at all.

She could redirect. Twist the narrative, pull him into her rhythm, make him dance to her tune instead of demanding forgiveness.

It was risky, maybe even desperate—but it was her only way out.

So she forced every ounce of panic down.

Pushed her shoulders back.

Plastered on the brightest, most casual smile she could manage.

And held out her hand.

"What are you doing down there, Cassius?" She said lightly. "Come on—get up already. Let’s take a bath together."

He blinked slowly, dazed, while she tugged lightly on his arm until he rose—awkwardly, towel clutched tight around his waist to hide the very obvious erection still tenting the fabric.

"Aqua...what do you mean taking a bath together?" He finally asked, voice hoarse.

"What do you think it means, silly?~"

Aqua slapped his chest lightly in a playful manner.

"It means, exactly what it means."

"You and me. We’re taking a bath together, right now."

Cassius stared at her like she had grown a second head, as she went on to say,

"The truth is when I heard you were bathing in here earlier, I got all nostalgic. Remember when we used to take baths together as kids? You’d splash me until Nanny had to separate us."

She let out a giggle and added,

"I missed that. So, I thought let’s relive those memories and do it again and take a bath together just like back in the past."

Cassius was flabbergasted, never expecting his own sister to say something like this.

"But, Aqua...that was ages ago. We were children. The nanny was always there supervising. And now..."

He gestured vaguely between them, cheeks darkening.

"We’re...grown up."

Aqua cut him off with a dramatic sigh, hands on hips.

"Ohhh, stop being such a prude, Cassius. So what if we’re older? We’re still brother and sister. That never changes. Never will."

"And I want to relive those old times."

"So, just for a little while, please? For your big sister?"

She grabbed his hand and tugged him toward the row of low stools and shower faucets along the wall.

Before he could protest again, she pushed him gently down onto one of the stools.

"Sit."

He sat—stiff, awkward, knees pressed together like he was trying to disappear.

Aqua crouched behind of him, grabbing a bar of soap and working up a lather between her palms.

"Here—let me wash your back. My little brother deserves to be pampered, right?"

She covered her hands in bubbles and began scrubbing circles over his broad shoulders and down his spine.

And feeling her touch—Cassius sat ramrod straight, every muscle locked.

Normally he would have been ecstatic. Joking. Teasing. Leaning into it.

After all his goal was to make her fall for him and lure her into bed like the one chosen by the Goddess of Debauchery would do.

But right now—under the lingering influence of whatever strange force still clouded his memories and instincts—he was drowning in embarrassment.

His cheeks burned crimson.

His hands clenched on his knees.

And he couldn’t relax at all. Couldn’t enjoy any of it.

Every touch of her fingers felt wrong and right at once, and the conflict made him want to crawl out of his own skin.

Aqua, meanwhile, kept her face perfectly calm, smiling, humming softly—

—even as inside she was screaming.

This was insane.

Too far.

Way too far.

Bathing her grown brother? After everything she had just done? After he had seen her come?

It definitely crossed the line of taboo.

But she couldn’t stop.

If she stopped—if she let silence fall—he would ask questions.

He would ask why she had been watching?

Why she had come?

Why she was still wet?

And she didn’t have answers she could give without shattering everything.

So she scrubbed harder.

Grinned wider.

And prayed desperately that he would let her drag him into this absurd, desperate narrative.

That he would pretend that none of it had happened.

Because if he didn’t...

She didn’t know how to survive what came next.
