Depraved Noble: Forced To Live The Debaucherous Life Of An Evil Noble!-Chapter 580: Perverted Sleeping Habit

Right now, Aqua found herself in a vast, beautiful field bathed in golden sunlight. The grass was a vibrant green, swaying gently in the warm breeze, and the sky above was a perfect, cloudless blue with the sun shining high and bright.

It was the kind of day that made the heart feel light.

Surrounding her were dozens of tiny slimes—no taller than a foot, their gelatinous bodies shimmering in soft colors: pinks, blues, lavenders, and mints.

Their big, round eyes sparkled with innocent curiosity, and tiny smiles seemed to form on their squishy faces.

They were the cutest creatures she had ever seen—not a trace of the monstrous, terrifying slimes from horror stories.

Aqua laughed delightedly, crouching down to pet one after another.

"Oh my goodness, how adorable are you all?" She cooed, voice full of wonder. "I’ve never seen slimes this cute before! Look at your little eyes—so sparkly! And your colors—so pretty!"

She scooped one up gently and tossed it lightly into the air; it wobbled happily before landing with a soft bounce.

The others crowded around her legs, nudging affectionately. She then spent what felt like hours playing—patting their squishy heads, rolling them like balls, letting them climb onto her shoulders and lap.

Eventually, exhausted from laughter and joy, she flopped backward onto the soft grass.

The slimes immediately swarmed over her in a gentle, living blanket—warm, weightless, comforting.

They covered her arms, her stomach, her legs, even nestling against her neck and cheeks.

But it didn’t feel threatening at all; it felt like the safest, warmest embrace in the world.

Aqua sighed contentedly, eyes half-lidded, a blissful smile on her face.

"It feels so nice...so good..."

But just as she was drifting into perfect relaxation, two of the slimes perched on her chest began to wiggle mischievously.

Before she could react, their bodies secreted a gentle, tingling liquid that dissolved the fabric of her nightgown and bra in an instant—leaving her full, heavy breasts completely bare beneath the open sky, pink nipples standing proud in the cool breeze.

Aqua gasped.

"W-Wait—!"

The two slimes wasted no time.

They latched onto her sensitive peaks, their soft, jelly-like bodies somehow mimicking the sensation of warm mouths—sucking, tugging, swirling

And the phe pleasure hit her like lightning.

"No—no, stop it!" She cried out, voice trembling. "You two—don’t be so naughty! We can’t—this is wrong!"

She reached to pull them away, but they clung like gentle suckers, refusing to budge, continuing their relentless teasing.

It felt good.

Too good.

Her back arched involuntarily, a helpless moan escaping her lips.

"Please...No...We shouldn’t..."

At the height of the overwhelming sensation, she screamed—

—and her eyes snapped open.

Darkness.

The familiar ceiling of Cassius’s bedroom.

The heavy, warm weight of blankets.

Her heart pounded wildly as reality rushed back.

"Just...Just a dream." She whispered, letting out a long, shaky sigh of relief. "Thank goodness...It was only a dream."

She pressed a hand to her flushed cheek.

"It must be because I saw all those slimes on the journey yesterday." She mumbled. "That’s why I dreamed something so strange..."

Then her expression shifted—confusion creeping in.

"But why in the world would they be sucking on my..."

She trailed off.

Slowly, dread rising, she glanced downward.

And froze.

Cassius—her sweet little brother, who had fallen asleep so peacefully in her arms was still hugging her tightly, face nestled against her chest.

But sometime in the night, her nightgown and bra had been tugged down—exposing both of her full, bare breasts completely. Her pink nipples also stood erect in the cool air.

And Cassius...

Cassius was latched onto one of them.

Sucking.

Deep, passionate pulls like a nursing infant desperate for milk.

"Lick!♡~ Mmph!♡~ Ahh!♡~ Suck!♡~"

His eyes were peacefully closed, breathing slow and even and seeing this horrifying sight, Aqua’s entire face ignited in a blazing blush.

One moment she had been cradling him wholesomely, like any loving older sister would—spooning her precious little brother, keeping him safe.

The next...he was suckling at her breast.

She didn’t know what to do.

For a fleeting, terrifying second, a thought flashed through her mind:

’Maybe...Maybe he’s attracted to me.’

’Maybe he sees me as a woman now, not just a sister.’

Back in the capital, she was considered one of the kingdom’s greatest beauties—courted by princes, dukes, even foreign dignitaries.

Her figure, especially her legendary chest, was the secret fantasy of half the noblemen in the realm.

They stared, they whispered, they proposed.

And Cassius...she had just learned how utterly depraved he had become with women—relentless, skilled, insatiable.

After years apart, had he looked at her returning form—curves fuller than memory—and lost control?

Was he, even now, consciously indulging in his big sister’s body?

The thought should have disgusted her.

Instead, a forbidden heat bloomed low in her belly, her thighs pressing together instinctively.

’No—no!’

She shook her head violently, scolding herself.

’What are you thinking, Aqua? This is your little brother!’

No matter how depraved he had grown with his wives, he would never—could never—see his own sister that way.

He had even been so shy, so embarrassed earlier, barely able to meet her eyes after the misunderstanding.

There was no way he would consciously do something like this.

But then she noticed something when she looked closer.

His eyes were firmly closed—not in pleasure, but in genuine sleep.

His breathing was slow, deep, and even.

His heartbeat against her side was calm and steady.

The way he suckled wasn’t even driven by adult lust, it was soft, instinctive, almost childlike.

Like a baby who had found comfort in warmth and latched on without thought.

She realised then then he was asleep.

He was genuinely asleep right now and Aqua felt a wave of profound relief wash over her.

’Thank the Goddess.’

If he had been awake—if he had been doing this consciously—she wouldn’t have known how to face him.

The confrontation would have been mortifying, devastating.

She had only just returned; she wasn’t ready for something so irreparably awkward to shatter their reunion.

But knowing he was truly asleep gave her a lifeline—an excuse she could cling to.

It wasn’t intentional.

It was just a habit.

Maybe the position triggered it: she had been cradling him so maternally, pressing his face to her chest like a mother with a nursing infant.

Perhaps, in his sleeping mind, he mistook her for a comforting, maternal figure and latched on instinctively.

It was even...oddly wholesome, in a strange way.

Or perhaps, it was because of his notorious naughty habits with his wives.

He was so accustomed to lavishing attention on women’s breasts, to sucking and teasing them all night long, that his body reacted automatically the moment soft flesh was near his lips.

And suprisingly, Aqua was exactly right on that second guess.

The truth was that Cassius had spent countless nights surrounded by eager, loving women who adored nursing him—awake or asleep.

His mouth had grown so used to the warmth, the softness, the taste, that it had become an unconscious reflex.

Like how some people grind their teeth or twitch in their sleep, Cassius sought breasts.

Whenever he sensed a soft, full pair near his face in the night, his hands would instinctively tug away whatever fabric was in the way, latch on, and begin that gentle, rhythmic sucking—slow, thorough, devastatingly skilled even in dreams.

Every wife and maid in the mansion also knew about this habit.

And not one of them minded.

In fact, they adored it.

Being suckled by their beloved young master—their husband even while he slept, was considered a privilege.

He was so gentle, so careful, so instinctively loving in his sleep that it felt like being cherished by an innocent, needy version of him—a "baby Cassius" they all secretly treasured.

They also never told him about his habits.

They feared that if he knew, he might consciously try to stop—embarrassed or worried about imposing.

But they wanted that sweet, vulnerable side of him forever.

So they let him indulge, night after night, keeping it their loving little secret.

And now Aqua—unknowingly—was experiencing the very same treatment.

With breasts as beautiful, full, and perfectly shaped as hers pressed against his face, there was no chance Cassius’s sleeping instincts would ignore them.

He suckled deeper, lips sealed tightly around one pink nipple, tongue swirling lazily, drawing soft, wet sounds into the quiet room.

"Ahh!♡~ Suck!♡~ Mmph!♡~ Lick!♡~"

But unlike his wives—who welcomed it, encouraged it, even guided his head closer—Aqua’s situation was entirely different.

She was his older sister.

Family.

Blood.

What he was doing, however innocent in intent, was deeply, undeniably taboo.

A brother’s mouth should never be latched to his sister’s bare breast—sucking with such tender, succulent care that her body was responding against her will.

She knew she should stop it.

She should push him away, wake him, cover herself—anything to end this forbidden intimacy.

But she couldn’t bring herself to.

Not when he looked so peaceful, so utterly content with his lips wrapped around her, soft sighs of satisfaction escaping between pulls.

Not when waking him would mean watching that horror return to his face—the fear that he had violated her again, worse this time.

He was already fragile from the earlier mistake.

If he woke now and realized what he was doing...he might pull away completely.

He might avoid her.

He might never let her hold him again.

And that terrified her more than anything.

So she tried gently to ease him off.

Her hands pressed lightly at his shoulders, trying to create space.

But his arms were like iron bands around her waist.

The more she pushed, the more firmly he latched—sucking deeper, drawing more of her breast into his warm mouth as if refusing to let go.

"Mmm!♡~ Ahhh!♡~ Slurp!♡~ Nnn!♡~"

Each time she tried to shift him, he only pulled harder, tongue flicking faster, sending fresh waves of pleasure through her.

"Mmm—!" A soft, helpless whimper escaped her lips before she could stop it. 𝐟𝕣𝕖𝐞𝐰𝕖𝚋𝐧𝗼𝚟𝐞𝕝.𝗰𝐨𝐦

She clapped a hand over her mouth, eyes wide, horrified at herself.

But the more she resisted, the more passionately he nursed as though her movement only encouraged him in his dream.

She realised then there was no escaping it.

She was trapped—pinned by his unconscious strength, forced to endure the slow, exquisite torment of her little brother’s mouth on her breast.

And worse...her body was responding.

Heat gathered between her legs again.

The lingering wetness from earlier had never fully faded, but now fresh arousal coated her thighs.

She could feel herself growing slick, swollen, aching.

Her nipples—especially the one in his mouth—throbbed with every pull.

She tried to think rationally.

This was wrong.

So wrong.

But another part of her, a quiet, secret part thought,

’My brother truly is a master at pleasuring women.’

The fact that he had a bed designed to absorb floods of feminine release was already proof enough of how often he made women squirt.

And he had done it to her as well—his own sister—with nothing but his fingers.

It also her first time she had ever squirted in her life.

She had thought the maids whispers about legendary lovers who could make a woman gush were exaggerated tales.

But Cassius had proven them true without even trying.

And now, even asleep, he was reducing her to a trembling, wet mess with nothing but his mouth on her breast.

His lips moved with perfect instinct—suckling deeply, then releasing with a soft, wet pop before latching again.

"Mmph!♡~ Mmm!♡~ Slurp!♡~ Ahhh!♡~"

His tongue rolled her nipple in slow, lazy circles.

"Nnn!♡~ Suck!♡~ Ahh!♡~ Mmmph!♡~"

Occasionally his teeth grazed just enough to make her gasp.

It was like watching and feeling a master at work.

She couldn’t believe he was truly asleep.

Yet his breathing remained slow and even, his body relaxed in deep slumber.

And as the minutes stretched on, as the gentle, relentless pleasure built higher and higher, Aqua found herself caught in an impossible place that she didn’t know how to or even if she wanted to escape from.
