Chapter 512: Repetition of Sin (R-18)

Repetition.

It was something every instructor loved to preach about—whether it was swordsmanship, discipline, or even the smallest habits. Do it once, you learn. Do it twice, you remember. Do it a hundred times... and your body starts to understand without thinking.

But repetition had a flaw.

Do the same thing over and over again, and sooner or later, it turned dull. Predictable. Empty.

There are some things—the more you indulge in them, the more you crave them. Drugs, alcohol, pleasure... sex.

They sink their hooks in deep, turning into something you can’t quite satisfy. No matter how many times you give in, it’s never enough. You always want more. And out of all of them, sex was the worst of it—the same hunger, the same restless desire, reflected clearly in both Katherine’s and Cassian’s eyes.

Cassian leaned back against the bed, his gaze fixed downward. Katherine was in front of him, her hair tied in that messy bun he kept wanting to grab, to control, to push her further. Her head moved back and forth in a steady rhythm, gagging sounds coming out of her mouth, her beautiful face looked obscene in a way, urging Cassian to mess it up more, make her do even more obscene things than what her mouth was currently doing—taking his big penis down her throat every time she bobbed her head down.

Her lips formed a tight suction around his penis, making her mouth look almost like a fish as they stretched every time she moved up and then slid back down again. It wasn’t exactly a beautiful thing to look at in a normal sense, but Cassian couldn’t have been more aroused, watching her do it right in front of him, completely focused, with his penis in her mouth.

A woman like her—so composed, so refined—reduced to this, making such expressions just to please him... it stirred something deeper in him.

The contrast only made it worse in the best way possible.

He just wished there was someone else there to see it too, to witness what he was seeing, as he asked impatiently, "What’s taking her so long?"

She pulled back with a soft pop, the sound lingering as she swallowed the saliva in her mouth. A wide smile spread across her lips, her yellow eyes gleaming like gems, shining with excitement. Her hands never stopped, still stroking him as she looked up and asked teasingly, "Why do you want her to do it instead of me?" 𝗳𝚛𝗲𝕖𝕨𝕖𝗯𝚗𝚘𝕧𝕖𝗹.𝗰𝗼𝕞

Cassian looked at her, clearly amused. He watched as her mouth opened again, the soft pink inside contrasting with her playful expression as she leaned in, her tongue tracing slow, deliberate movements.

He shook his head slightly, meeting her raised brow as she held him firmly at the base.

"I want her to see you do it," he said, a faint smirk forming, "so she can learn from the best..."

Just as she was about to say something, the bathroom door opened.

Ravees stepped out, cheeks flushed, her damp hair clinging lightly as if she had just washed up. She looked fresh—but also nervous. She was fully dressed in her night clothes, a loose linen shirt and equally loose pants.

Katherine glanced at her and let out a soft, amused breath.

"Well... if she wants to, who am I to say no?" she said lightly, a knowing smile playing on her lips. Both of them were well aware Ravees had been listening from behind the door.

That only made Ravees blush even harder.

"I... I don’t want to, my lady..." she murmured, her voice low and hesitant.

Katherine’s brow lifted slightly, her hand still moving as she looked at her with clear curiosity.

"Why not?" she asked, almost teasing. "You two were fucking last night after I passed out..." Her smile turned a bit sharper, more playful. "I was actually expecting you’d do it again tonight... so I could watch."

Ravees looked even more embarrassed, clearly troubled by Katherine’s words. She could have just said no—she could have held onto that reason, the simple truth that she didn’t want to keep betraying her husband.

But deep down... the desire hadn’t gone away.

The memory of it lingered—the pleasure, the overwhelming rush, the way it had made her lose herself. It crept back into her thoughts, uninvited but persistent, making her hesitate.

What if she refused? Would Katherine be upset? Would she be pushed out of the room entirely? And if that happened... how was she supposed to stay in control of the situation? How was she supposed to keep her safe if she wasn’t even there?

Her mind kept twisting things, coming up with excuse after excuse—anything to justify staying, anything to let it happen just one more time.

And the truth was... before Katherine had walked in, things had already been heading there. The dare, the way they had gotten close—it hadn’t been far from crossing that line again.

Her gaze dropped, almost against her will, drawn to the way Katherine’s hand kept moving, slow and steady. The sight alone made her swallow hard, her thoughts slipping further.

She hesitated... then finally nodded, her voice quiet.

"You... you can go first, my lady..."

"Of course I’m going first... now go on, sit next to him," Katherine said with a small smile. There was a faint tinge of jealousy beneath it at Ravees agreeing—but at least she still had the first turn.

Meanwhile, Cassian was the only one truly enjoying himself from both sides. His gaze followed Ravees as she slowly walked toward them, clearly amused by the hesitation in her steps.

She avoided looking directly at what Katherine was doing, her eyes drifting elsewhere as she sat down with a bit of distance between them.

That only made him smirk.

The distance didn’t matter—his hand could still reach her.

His fingers closed around her thigh, pulling her attention back to him as he asked casually, "Why’d you wash up...? You’re just going to get messy again."

His hand slid further along her inner thigh, slow and deliberate.

Ravees tensed instantly, her legs pressing together as she shot him an angry glare.

And by then, Katherine had already resumed, the rhythm picking up again like nothing had interrupted her at all.

Soft, wet sounds filled the room, drawing Ravees’s attention despite herself. She tried to resist—but couldn’t. Her eyes shifted, betraying her as she looked, completely ignoring Cassian’s hand slowly spreading her thighs.

"Slurp... slurp... slurp..."

The sounds alone were enough to make her flush deeper.

To see it, though—that was worse.

A woman like Katherine... someone so composed, so dignified, with a face that could rival anything beuitfull in the world—now reduced to something so openly lewd.

Her tongue slurping around his wide penis head as she wrapped her lips around it, stretched wide, making her perfect face look coarse, as Cassian’s penis was too big. Ravees couldn’t imagine how her small mouth could take it inside her, veiny and hard. She didn’t know how it fit inside her vagina, let alone her mouth.

And more than that—why?

The answer came when she looked at Katherine’s eyes.

They weren’t strained or unwilling.

They were... bright. Focused. Almost indulgent—like she was savoring something she truly enjoyed, like she was exactly where she wanted to be.

That realization made something shift in Ravees’s thoughts.

Maybe... Katherine wasn’t any less of a pervert than Cassian after all.
