Chapter 582: Changing Heart

Cassius’s eyes fluttered open to the gentle glow of morning sunlight filtering through the heavy curtains.

Birds chirped cheerfully outside the tall windows, their song mingling with the faint rustle of leaves in the chilly winter breeze.

For a moment he simply lay there, a lazy, contented smile spreading across his face.

Even after all this time, he still wasn’t completely used to it.

Back in his old life, mornings had meant the harsh buzz of an alarm clock in a apartment bedroom, the distant hum of city traffic seeping through thin walls, the quiet loneliness of waking up alone.

Now he woke in a sprawling mansion, on a bed big enough for half a dozen people, surrounded by luxury and more importantly love he had never dreamed of.

He was profoundly grateful to the Goddess of Debauchery who had sent him here.

At first he had resisted.

But now?

No regrets.

None at all.

Especially because most mornings began with soft lips wrapped around his cock, warm mouths and eager hands lavishing him with pleasure before he even fully woke.

His wives and maids took turns—or sometimes worked together—milking load after load from him in the most blissful wake-up call imaginable.

He stretched slightly, expecting to feel the familiar weight of a head between his legs or the gentle suction that often greeted him at dawn.

But...nothing.

No warm mouth. No teasing tongue. No soft breasts pressed against his thighs.

A small pout formed.

"Pity." He murmured to himself, voice husky with sleep.

He turned his head, ready to nudge whichever wife was closest and request a favor—

—and his entire body jolted upright, heart slamming against his ribs.

Aqua.

His sister.

Sleeping right beside him.

And not just sleeping.

Her position was...vulnerable didn’t even begin to cover it.

The heavy blanket had been kicked completely aside sometime in the night.

Her nightgown was bunched high around her waist, exposing everything below.

Her massive breasts—fully bare, bra tugged down beneath them spilled freely to either side, heavy and soft, swaying gently with each breath.

Her pink nipples stood proud and erect in the cool morning air, surrounded by a constellation of faint purple marks.

Her legs were also splayed in sleepy abandon, thighs parted just enough to reveal her soaked purple underwear clinging transparently to her mound, the fabric darkened and glistening with obvious arousal.

A faint sheen of moisture coated her inner thighs.

Cassius’s mouth went dry.

Memories of the night crashed over him in vivid, mortifying detail.

The mistaken identity.

Fingering her until she squirted.

Forcing his own sister to climax.

And then...sleeping beside her.

He had thought it settled—she had forgiven the misunderstanding, hugged him, reassured him.

But seeing her like this, clearly still affected sent a complicated rush of emotions through him.

Relief that she hadn’t hated him.

Guilt that he had done this to her.

And—inescapable—raw, burning desire.

Because God, she was beautiful.

He leaned closer, almost unconsciously, eyes tracing the flawless curves he had only felt in darkness.

Her breasts were even more breathtaking in daylight—full, heavy, perfectly shaped, skin pale and creamy. He reached out, fingers ghosting over one soft mound, thumb brushing a stiff nipple.

So similar to Isabelle’s.

Same plush weight, same responsive peak that hardened further under his touch.

The only real difference was Aqua’s slightly taller frame.

Everything else—curves, softness, sensitivity—was nearly identical.

No wonder he had mistaken them in the dark.

But then his gaze caught something else.

Faint blue-purple marks dotted her pale skin—clustered especially around her areolas and nipples.

Hickeys.

Dozens of them.

He froze.

Last night, when he had glimpsed her cleavage, her skin had been completely unmarked—smooth and porcelain.

Now it was covered in the unmistakable evidence of passionate, prolonged sucking.

For a moment he worried he had done it consciously and simply forgotten.

But then memory supplied the answer.

It was the same thing that happened with his wives.

He would wake sometimes to find their breasts similarly marked, and when he asked, they always blushed and blamed ’mosquitoes.’

Specialized mosquitoes that only targeted breasts, apparently.

He had never quite bought it, but in a fantasy world, who knew?

Now, seeing the same marks on Aqua, he wondered if those mosquitos attacked her sister as well.

Well, with breast like hers it made sense that even a insect wanted to suck on them.

But then his gaze drifted lower as he noticed something else.

Her soaked underwear clung transparently to her lips, the fabric darkened and heavy with arousal.

Even the special bed hadn’t fully absorbed everything—there was still a faint dampness beneath her.

He frowned in genuine concern.

He had seen it before—wives who fell asleep in wet underwear after particularly intense nights sometimes woke with fevers or discomfort.

He didn’t want that for Aqua.

Not when she had just returned.

So, with careful, practiced gentleness, he began sliding her underwear down her hips—planning to remove them, clean her discreetly, and replace them before she woke.

He lifted her hips slightly with one hand, easing the fabric over her thighs.

Strings of slick arousal clung between the cloth and her skin, stretching and breaking as he pulled.

And finally, he exposed her fully.

Her pussy was just as breathtaking as the rest of her—plump outer lips, glistening pink inner folds, a slightly larger-than-average clit that he knew from last night was exquisitely sensitive.

It was just like Isabelle’s—the only difference being that her sister probably has blue pubic hair which would’ve been a sight to witness.

And right now, he couldn’t help but stare for a moment, appreciation and desire warring with brotherly concern.

But duty won and he decided to help her out.

But just as he was about to slip the underwear fully off her ankles a soft, concerned voice broke the silence.

"Cassius...what exactly are you doing right now?"

"Why are you taking my underwear off?"

He froze.

Slowly—dreading what he would see—he turned his head.

Aqua was awake.

Propped on one elbow, cheeks flushed crimson, sapphire eyes wide with shy confusion and embarrassment.

She wasn’t angry.

Just...bewildered.

Cassius’s brain short-circuited.

He raised both hands quickly, still holding her soaked underwear, looking every bit the guilty perpetrator.

"Hold on—hold on, Aqua, just—wait!"

He stammered, voice higher than usual.

"I know how this looks. I know this makes me look really, really bad. But let me explain!"

Aqua pulled the blanket up to cover herself, clutching it to her chest, eyes darting between his face and the underwear in his hand.

Cassius took a deep breath.

"After...what happened last night." He said awkwardly, cheeks heating. "Your underwear got...wet. Really wet. You were basically sleeping in a puddle down there."

"And that’s bad—it can make you sick. My wives have gotten fevers before when they’ve fallen asleep like that after...intense nights."

He moved a little back, avoiding her eyes.

"I didn’t want you to get ill right after arriving. We just got you back and I couldn’t let that happen. So I was going to take them off, clean you up a bit, and put fresh ones on while you slept. I’ve done it tons of times with the others."

"I’m actually pretty good at it—they usually don’t even wake up."

He finally met her gaze, offering a sheepish, hesitant smile.

"But...clearly I wasn’t stealthy enough this time."

"You woke up after all."

Aqua’s gaze flickered up to him—hesitant, shy, cheeks still burning crimson. She clutched the blanket tighter to her chest, but her sapphire eyes held no anger, only a uncertain vulnerability.

Cassius’s heart hammered. He braced himself for whatever was coming—scolding, tears, awkward distance. Anything.

Finally, in a small, trembling voice, she asked,

"Did you...see?"

She swallowed hard, forcing the rest out.

"Did you see...what was underneath?"

Cassius felt his stomach drop.

He didn’t want to answer—it was crude, embarrassing, and admitting it would only make him look worse.

But lying to her face felt impossible.

So he nodded slowly, eyes dropping to the bedsheets.

"I did." He admitted quietly. "I didn’t mean to stare. It just...caught my eye when I was trying to help."

"I’m sorry. Really sorry."

He waited for the explosion.

The panic.

The tears.

The shouting.

The rightful scolding for being a perverse brother who stripped his sleeping sister and ogled her most private places.

He deserved it.

He had screwed up and regretted the impulsive decision the moment she spoke.

But none of that came.

Instead, Aqua simply looked down, fingers tightening on the blanket, and murmured in a timid, almost resigned voice,

"I guess...it’s fine."

Cassius’s head snapped up, eyes wide.

She gave a tiny, awkward shrug, still not meeting his gaze.

"You were trying to help me, after all. You explained it...and I believe you."

Then, with a soft, flustered laugh that didn’t quite hide the tremor in her voice, she added,

"Not to mention...I’ve already seen you completely exposed too. Remember? I barged in that one time and...well...now you’ve seen me. So...we’re even, aren’t we?"

She offered a gentle smile—small, shy, but genuine.

And Cassius stared at her, utterly dumbfounded.

This wasn’t the reaction he had prepared for.

Not even close.

She should have been furious.

Embarrassed beyond words.

Anything but...accepting.

He had no idea how to process it.

But the truth, of course, was far more complicated for Aqua.

Beneath her calm exterior, her heart was racing, her mind spiraling.

Waking up to her brother sliding off her soaked underwear had sent her into a panic—mortification, confusion, a rush of taboo heat she didn’t want to acknowledge.

But then guilt had crashed over her like a tidal wave.

Because she remembered what she had done in the night.

How she had taken advantage of his sleeping state.

How she had actively pressed her breast into his mouth, held him there, encouraged him all for her own selfish pleasure.

Compared to that, his actions this morning done with genuine concern for her health were nothing.

She was the one who had crossed the real line.

She was the naughty one.

The depraved one.

The sister who had used her innocent little brother’s unconscious body for forbidden satisfaction.

So how could she possibly blame him?

All the fault was hers.

And right now, all she felt was overwhelming remorse and a desperate desire to be comforted—to feel safe again.

Normally, she would have sought her mother or the Empress, people who had always been her safe haven.

Or Joy, or Maria.

But right now, none of them felt close enough.

The only person who could ease the storm inside her was the very brother in front of her.

The one she had wronged.

The one whose presence alone made her feel warm, protected, whole.

So, voice small and trembling, she looked up at him with pleading eyes.

"Cassius...Is it okay if...if you give your sister a big, deep hug this morning?"

She hugged her arms around herself, as if holding back shivers.

"I feel...out of sorts. For some reason. And I think...I would feel much better if you held me really tight."

Cassius blinked, surprised by the request.

But then he saw it—the faint tremble in her shoulders, the glassy sheen in her eyes, the way she seemed to be holding herself together by a thread.

She was struggling.

Really struggling.

Whatever was going through her mind, she needed him right now.

Without hesitation, he opened his arms wide, sitting cross-legged on the bed with a warm, reassuring smile.

"Come here, Aqua....Come get the hug you need."

Aqua didn’t hesitate.

She threw the blanket aside completely—breasts still bare, nightgown still bunched, everything exposed and crawled quickly across the mattress.

Her heavy breasts swayed and bounced with the movement; her bare ass and pussy flashed openly as she moved.

She didn’t care.

She needed this more than modesty.

In seconds she was in his lap—legs wrapping tightly around his waist, arms flinging around his neck, face burying into his chest.

She pressed her entire naked front against him—soft breasts flattening against hard muscle, bare pussy settling directly on his chiseled abs.

Warmth.

Safety.

Love.

All the guilt and turmoil melted away the moment she felt his strong arms close around her, his familiar scent enveloping her.

Cassius roo held her tightly, one hand rubbing slow, soothing circles on her naked back.

For a moment, his usual instincts flared.

He wanted to comfort her the way he comforted his wives: soft kisses along her neck, whispered sweet nothings in her ear, maybe even a little more if she needed it.

But the old memories surged up again—images of a small girl protecting a crying boy and he couldn’t.

So he simply held her.

Tight.

Protective.

Warm.

And in that embrace, despite everything, he felt it too—a genuine, deep familial warmth.

This wasn’t just desire.

Right now, holding his trembling sister, he truly felt like her brother.

He wanted to protect her.

To make her feel safe.

To never let anything hurt her again.

They stayed like that wrapped together, skin to skin, hearts beating in sync for a long, quiet moment.

Until the door suddenly creaked open.

Isabelle stepped in, tray of breakfast tea in hand, ready to greet and wake her young master with her usual bright smile.

But the sight in front of her stopped her dead.

Her beloved young master, sitting cross-legged on the bed.

His naked older sister straddling his lap—legs wrapped around him, bare breasts pressed to his chest, bottom exposed, everything on full display—clinging to him in a deep, intimate embrace.

Isabelle’s eyes widened.

For a heartbeat she stood frozen.

Then Cassius noticed her.

He met her gaze over Aqua’s shoulder and quickly pressed a finger to his lips.

"Shhh..."

Isabelle blinked once...twice...

Then a knowing, amused smile curved her lips.

She gave a small, understanding nod.

Of course.

Even his own sister couldn’t resist his charm.

He was irresistible, after all.

Without a word, she backed quietly out of the room, closing the door softly behind her.

Cassius and Aqua remained alone—wrapped in each other’s arms, sharing a bond that felt purely sibling...

Yet was slowly, inevitably shifting into something deeper.

Something Aqua was not ready to name.
