‘But I can’t burden him with that. Now that we’ve returned to being siblings… I’m Leah Verbaine. I can’t allow myself to cross that line. He has to marry someone and continue the family line someday.’

Even if Zion doesn’t want that now, he will eventually need to take a wife, have children, and uphold the family legacy. 

She could no longer be a weight he had to carry. 

“I hope you won’t hide anything from me. After all, we’re family.”

Zion murmured softly as he left the prayer room. 

The word family made Leah’s heart waver even more. 

Because they were family, she couldn’t allow herself to commit any further sins.

***

The first night in the temporary home, Leah couldn’t sleep. 

No matter how hard she tried to close her eyes and relax, sleep eluded her. Her heart pounded in her chest, and an unfamiliar warmth spread through her body, leaving her restless. 

‘What should I do…?’

Before moving here, she had spent a month living in a rented mansion. It had been a place bustling with servants, and opportunities to be alone with Zion had been rare. 

But now, in this small, isolated house, there was no one else—just the two of them. 

The workers who had been building the mansion had left, and in the vast, desolate surroundings, only Zion and Leah remained.

The thought of being alone with Zion kept Leah awake. 

‘What am I going to do…?’

Leah pressed her hands to her br*ast in a vain attempt to calm herself, but it brought no relief. 

No matter how much she touched herself, whether on her chest or elsewhere, she couldn’t find the satisfaction she was looking for. 

Her body, however, hadn’t forgotten the pleasure it had once experienced – the pleasure given by none other than Zion. 

“Brother… I want you to touch me…”

How dirty her desire was. 

How could she long to be held like this by her own brother? 

“I am dirty… I’m obscene…”

In the end, it was undeniable that the dark, forbidden desires within her had summoned the demon. 

Finally, Leah rose from her bed, unable to suppress the turmoil any longer. 

Wrapping herself in nothing but a blanket, she quietly stepped out of her room. 

The small living room separated her room from Zion’s, their doors facing each other in the stillness of the night. 

Pushing open his door, her eyes immediately fell on him – lying peacefully under the covers, sound asleep. 

Closing the door gently behind her, Leah approached his bed with cautious steps. 

Without hesitation, she climbed onto the bed where Zion lay, lifting the blanket that covered him and slipping underneath. 

As she settled under his blanket, the one she had draped over herself slipped from her shoulders and fell silently to the floor. 

Now lying beside Zion with nothing to shield her, Leah laid a trembling hand on his chest. 

“Leah?” 

Zion’s voice, heavy with sleep, carried a note of confusion as his eyes fluttered open. His puzzled gaze met hers, taking in the unexpected sight of her lying so close to him. 

“Brother…”

“What’s wrong, Leah?”

“I… just…” 

The words caught in her throat. How was she going to explain this? The very thought of crawling under his blanket in such a vulnerable state and pretending it meant nothing was utterly absurd. 

“Are you scared of sleeping alone? It’s probably because it’s your first night here.”

“Can I sleep here?” 

“Of course.” 

Zion’s arm slipped around Leah’s body. 

“Why aren’t you wearing anything, Leah?” 

Leah’s face flushed at the words. 

“Well… that’s because…” 

“Did you take it off because you wanted to be held by me?” 

At his question, Leah nodded silently instead of answering. 

“Did you want to be held by me?” 

“Mm-hmm…” 

“Since when?” 

“For a while… all the time…” 

“Do you know that this is a sin? That giving in to your desires instead of seeking purification and doing this to your brother is wrong?”

“I know…”

“So this isn’t about a purification ritual – you want to do something inappropriate with me?”

“Yes…”

She confessed, lowering her gaze as heat flooded her cheeks. What she wanted now wasn’t purification or absolution. She simply wanted to be held by her brother. She wanted to feel the pleasure of his embrace. 

“Then we’ve both committed a sin. An unforgivable sin.” 

“I know…” 

“But since we have already sinned, one more will make no difference.” 

With a whisper, Zion’s hand began to caress Leah’s skin. 

As his touch moved over her, heat surged through Leah’s body. 

This obscene heat felt intoxicatingly sweet. 

“More… touch me more, brother…” 

“Where? Your n*pples?” 

“Yes… all of me…” 

“Will you touch me then?” 

“Uh, where?”

“You should touch my d*ck too. Can you do that?”

Leah nodded, her ears flushed.

“Now put your hand down and touch my d*ck.”

Leah put her hand down.

Then Leah immediately touched his d*ck.

Zion’s d*ck was already swollen and aroused.

Leah could barely hold on to the hot, throbbing d*ck and gasped for breath.

“Leah… my dear sister… .”

Zion climbed onto Leah.

The blanket slid down to reveal Leah’s n*ked body in the dim light of the candle beside the bed.

“You are so beautiful… my dear sister.”

This was the image Zion had secretly longed to see – Leah, consumed with desire, her soft moans betraying her longing for him. 

His own sister, aching for his touch. 

“Mm… ah…”

As Zion’s hands gently kneaded Leah’s soft br*asts, she tilted her slender neck, her fiery red hair spilling untidily around her. 

Her flushed cheeks and tear-filled eyes, framed by her innocent expression, contrasted starkly with her voluptuous figure and the vibrant intensity of her crimson hair. 

It all stirred Zion’s lustful desires.

This beautiful younger sister, now breathless beneath him, was someone Zion had watched grow from infancy. 

He had guided her first steps, cared for her and raised her with his own hands. But now she lay beneath him, longing for him. 

This was the moment Zion had been waiting for.

“My dear sister. You have no idea how beautiful you are.”

He leaned down and gently sucked on Leah’s lips.

“Mm…”

Her breath mingled with his as their lips met. 

Her lips were softer than silk, their texture utterly exquisite. 

As he gently nibbled at her soft lips, parting them, his tongue slipped inside, exploring and meeting the warm, moist touch of hers. 

“Mm, ah, mm…”

Leah, gasping as if struggling for breath, let out a series of soft, trembling moans as Zion’s lips explored hers and his hands gently caressed her skin. 

Their tongues entwined in a passionate dance, the wet, intimate sound of their movements filling the space between them. 

“Ha… ha…”

As soon as he pulled his lips away, Leah gasped.

“Leah. Turn around.”

Zion hugged Leah from behind as she obediently rolled over at his words.
