Chapter 776: Breaking All Taboos

Aisha, watching the sight with a flustered look on her face, finally couldn’t help but speak up.

"Well." She said quietly. "Who would’ve thought that Aqua of all people would have this side of her?"

She shook her head.

"I already knew she was in love with her brother, but I didn’t know it was to such an extent."

She watched Aqua bounce and moan, her eyes wide.

"She looks so obsessed right now. So scary. Heh. I’m honestly sure she’d finish us off if we tried to disturb her."

She turned to Julie for agreement.

But Julie wasn’t even focusing on her.

The knight had her legs spread wide, two fingers buried deep inside her pussy as she fingered herself openly. Her other hand twisted her nipple.

Her eyes were fixed on Aqua and Cassius.

"Yes, yes." She whispered under her breath. "Fuck your brother, Aqua. Fuck him harder. Make him show you how much he loves you. Pound him!"

She pushed her fingers inside with increasing urgency, her hips bucking against her own hand.

She looked like she was imagining herself in that position, a look of pure happiness on her face.

Aisha snapped.

"Captain, what the hell are you doing right now?" She whispered harshly. "Is this really the time to be doing such a thing!"

Julie turned to her with an embarrassed but unrepentant look, her cheeks flushed.

"I’m sorry, Aisha, but honestly...this really is the best time to do this thing."

She looked back at the scene, her voice trembling with excitement.

"To see a brother and sister doing such things—even though it’s so wrong and taboo and goes against everything society’s taught us—it’s just too hot to watch!"

She shuddered.

"And to know that brother is my husband, the same man who’ll give me children in the future..."

She pushed her fingers deeper. "It’s just so hard to think about without touching myself!"

She whimpered.

"Not to mention that in the future, their babies will have to ask who exactly is their father and who exactly is their uncle."

"Hehe. The entire family tree will be completely messed up. And just thinking about it is so...so...so exciting!"

She drove her fingers deeper into her pussy and squirted on the spot, as if this was the most euphoric sight she had ever seen.

Honestly, after hearing Julie’s description, even Aisha couldn’t help but feel a spark of excitement.

When she looked back toward the scene of Aqua basically forcing herself on Cassius and slamming her fat ass onto his cock while forcing him to choke on her breasts, she too couldn’t help herself.

Slowly, one hand went toward her pussy. She pushed two fingers inside and started stroking her clitoris, while the other went to her nipples. She started touching herself while watching the sight.

Julie, who noticed this, couldn’t help but smirk.

"What’s this, Aisha?" She said, her voice teasing. "You always complain about what I do. You call me a pervert all the time, acting as if I’m some sort of disgrace. But now..." She narrowed her eyes. "What exactly do you think you’re doing?"

"S-Shut up, Captain!" Aisha replied, her cheeks burning. "Mind your own business!"

She continued touching herself, getting off on the exciting sight before her.

Julie was happy to see that her sister was also finding her hobby favorable. She also couldn’t help but get even more excited.

Just like that, both sisters—one human and one cat girl started touching themselves on the bed while watching the scene unfold.

Aqua was reaching her peak.

"I feel it coming—!" She cried out. "I feel something coming—! All those previous nights, whenever I touched myself and thought of you, I always had this feeling building inside me!"

"But it never ended up happening. I was always left unsatisfied, no matter how much I fingered myself!"

She looked down at her brother with loving eyes.

"But right now—watching this cock smash against my pussy, feeling it inside me—I feel it coming—! It’s coming—! Oh my god, yes, yes, yes—!"

She felt his cock throbbing inside her, growing larger, harder.

"I also feel you coming, Cassius—! Your body’s reacting—! It’s reacting to your own sister, you dirty, dirty boy—!"

She laughed breathlessly.

"But who cares? Let’s do it! Let’s do it together! Let’s come together like the brother-sister pair we are!"

She pushed herself down all the way until they were pressed flush against each other.

"Let’s come—! Let’s come—! Let’s come together—!"

And then she did.

"CASSIUS, I’M COMING! I’M COMING FROM MY LITTLE BROTHER’S COCK!"

She kissed him at the same moment, and her orgasm crashed over her like a wave.

"Schlurp!♡~ Splish!♡~ Splat!♡~ Squish!♡~"

She squirted—an unstoppable amount, raining down onto Cassius’s crotch, soaking them both.

But this was actually too much of an amount, probably because she had a water elemental affinity.

"Gloop!♡~ Drip!♡~ Splurt!♡~ Plop!♡~"

Her body kept leaking out almost as if she was pissing herself, pouring her love all over Cassius.

And Cassius, despite the calm look he had on his face—couldn’t hold back anymore.

He let the semen in his balls burst out and fill Aqua up, completely enveloping her womb in thick white batter.

"Thwap!♡~ Schlurp!♡~ Squish!♡~ Sploosh!♡~"

Instantly, Aqua moaned out.

"Yes, yes, your coming!♡~ I can feel my brother filling me up!♡~ He’s pushing his baby fluid inside of me!♡~"

Tears of joy streamed down her cheeks.

"I’m going to get pregnant—pregnant with my brother’s baby!♡~ I’m so happy!♡~"

She felt herself getting filled up, warmth spreading through her core.

Julie and Aisha aleo could no longer hold back.

Julie cried out. "I’m coming, I’m coming!"

Aisha moaned. "Me too! I’m actually coming from watching a brother and sister have sex!"

Both women climaxed at once, squirting large amounts of fluid from their pussies that arced through the air and rained down onto Cassius and Aqua, who were lying on top of one another.

But Aqua didn’t seem to care at all. She seemed to be in a world of pure bliss, whispering to herself.

"I love you, little brother. I love you so much." She nestled against his chest. "This...This is the happiest day of my entire life."

And Cassius, who was finally freed from his invisible shackles, could move again.

He immediately wrapped his arms around Aqua, pulling her into a deep embrace with a satisfied smile on his face.

—

Five minutes later...

Aqua’s heart was still racing, her breath coming in short, shaky gasps. Her body was pressed against Cassius’s and she could feel every inch of him. His chest against her breasts.

His thighs against hers. His cock, still buried deep inside her, twitching with every beat of his heart.

But as the euphoria began to fade and her mind cleared—the reality of what she had done crashed down on her like a wave of ice water.

’Oh no.’

’Oh no, oh no, oh no!’

She had pounced on her brother! Again!

Just like in the bathroom, she had thrown herself at him, unable to control herself, unable to stop!

But this time was different.

Back then, she had been influenced by her bloodline.

The fairy blood had burst out of her, turning her into an animal driven by instinct. She could blame that. She could tell herself it wasn’t really her.

But this time? It wasn’t her blood that had driven her this time.

It was her feelings. Jealousy. Possessiveness. Envy.

And above all else—overwhelming, consuming, undeniable love for her brother.

All of it had burst out of her, flooding her mind until there was no room for anything else.

And now...

Cassius’s cock was still inside her. Throbbing. Moving. She could feel every pulse, every twitch, every inch of him filling her.

A deep, suffocating sense of humiliation and shame washed over her.

’What have I done?’

But more than the shame, more than the humiliation, there was fear.

Terrifying, paralyzing fear.

’Cassius is going to hate me.’

She thought back to everything that had happened today. The way he had ignored her. The way he had pushed her away.

The way he had treated her like she didn’t exist, like she wasn’t a woman, like she was just his sister and nothing more.

He didn’t want her. He had made that clear all day.

So now—after she had thrown herself at him, after she had forced herself on him—he was definitely going to despise her.

He was going to push her away. He was going to tell her to leave, to go back to the capital, to never come back.

Tears welled up in her eyes.

’No. No...I don’t want to leave him. I don’t want to go back to the capital. I-I don’t want to spend the rest of my life without him.’

But what choice would she have? If Cassius rejected her and told her to go—she couldn’t stay.

She couldn’t force herself on him. She couldn’t be that kind of person.

She felt everything breaking apart. The fragile hope she had been holding onto, the dreams she had been secretly nurturing, the future she had imagined—all of it crumbling to dust.

She was about to cry. Right there, naked, with her brother’s cock still inside her, she was about to break down completely.

That is until—

A hand stroked her back.

Gentle. Warm. Rhythmic.

"I’ve gotta say." Cassius’s voice came, casual and almost cheerful. "It’s been a while since someone rode me like that."

Aqua blinked.

’...What?’

"Don’t get me wrong." He continued, still stroking her back. "Everyone in the household still loves to ride me from time to time. They treat my cock like a horse."

He chuckled.

"But they only last a few seconds before they collapse. Even the strongest one, Isabelle..." He thought for a moment "...maybe a few minute? Tops. Then I have to do all the work."

He pulled her closer, his arms wrapping around her.

"But you? You rode me properly. Aggressively. For a good long while." He sounded genuinely pleased. "It was refreshing."

Aqua stared at him in disbelief.

He wasn’t angry.

He wasn’t disgusted.

Instead, she found herself looking into warm, affectionate eyes.

The same look a lover might give after a passionate night together.

Thankful. Satisfied. Content.

She couldn’t believe it.

"Cassius..." Her voice came out small, trembling. "You’re not angry with me? You’re not...disgusted by what I did?"

He raised an eyebrow. "Of course not."

He gave her ass a firm squeeze, making her yelp.

"In fact, I should be thanking you. Your pussy was so tight, and the way you rode me up and down..." He shook his head admiringly. "Thank you for giving me such a wonderful night."

The lewd words barely registered.

What actually mattered was that her brother wasn’t angry. He wasn’t disgusted. He wasn’t pushing her away.

He was thanking her.

"B-But how?!"

The words burst out of her. Aisha and Julie, who had been quietly watching from the bed, perked up.

Even they seemed to sense that this was a pivotal moment.

"How can it be like this, Cassius?!" Aqua pushed herself up, her breasts pressing against his chest, her eyes searching his face.

"Aren’t you supposed to be angry?! Aren’t you supposed to push me away??"

She shook her head in confusion.

"You ignored me all day. You said you wouldn’t look at me like a woman. Y-You treated me like I was nothing—like I was just your sister and nothing more."

A flicker of guilt crossed Cassius’s face.

"So how—" Her voice cracked "—how can you not care about what happened?"

"How can you be happy about it sister forcing herself on you once again?"
