Synopsis
I reincarnated with nothing — no rank, no bloodline, no name in any record that mattered. The perfect target. A succubus found me in my first week and decided I was hers to drain but She wasn't wrong. For about an hour. Then something buried deep in my blood woke up, and the system it carried had one very specific ability: whatever I drain from someone, I keep. Their experience. Their skills. And ten percent of who they are. She came to take everything from me. Now she can't leave. I didn't plan to build an empire. I didn't plan to become something the gods buried once already but the System doesn't care about plans — and neither, it turns out, do I. [System · Isekai · Harem · Empire Building · R-18]

Chapter 1 - Awakening

As I slowly opened my eyes, my vision blurred, but after a moment, everything came into focus. I was in a stone chamber lit by candles. The walls were made of grey stone, smooth and unmarked. The floor was also stone, but it had a thick carpet woven with intricate patterns to soften our steps. In the center of the room was a large circular bed, resting on top of a raised platform covered in the same carpet.

Standing before me, her silhouette casting long shadows across the walls, was the one who had purchased me. She wore a dark flowing gown that fell to her ankles, clinging to her every curve and revealing almost nothing of her form. Her long black hair cascaded down her back, framing her pale face. Her crimson eyes were fixed on me, unblinking and unreadable. Two small elegant horns protruded from her forehead, adding an air of mystery to her already ethereal appearance.

A sigh escaped my lips as I took in her beauty. She was beyond stunning, her features almost otherworldly. Yet, I couldn't help but feel a mix of fear and resignation at the knowledge of my fate. I had been sold to her, a succubus, to be used and discarded. I had survived five weeks in this strange world alone, stealing food and dodging authorities. But now, I was trapped, with no escape.

As my thoughts drifted back to how I had ended up here, I couldn't suppress a bitter smile. I remembered the shopkeeper's face, the look of betrayal in his wife's eyes, the coldness of the guards as they dragged me away. I had been framed for harassing the shopkeeper's wife, even though she had propositioned me herself. The shopkeeper had been so angry that he had accused me of stealing as well, and the king had decided that I was an easy target to teach a lesson to the common folk.

My internal monologue was interrupted by the sound of footsteps echoing in the otherwise silent room. The succubus walked slowly towards me, her graceful movements captivating. She stopped a few feet away from me, close enough for me to smell her sweet perfume. Her eyes never left mine, as if she was waiting for me to make a move.

I couldn't help but chuckle at the irony of my situation. Here I was, a mere mortal, staring death in the face, and yet, I couldn't help but feel calm. Perhaps it was the realization that there was nothing I could do to change my fate, or maybe it was the fact that she was so beautiful, trapped in this chamber with her for eternity didn't sound so bad.

As she continued to stare at me, I couldn't help but wonder what she was thinking. Was she assessing me, deciding whether or not I would be suitable for her purposes? Or was she simply enjoying the power she held over me, knowing that in a matter of moments, she could end my life with a thought?

I felt a sudden rush of heat in my groin, my body betraying me even in this dire situation. I clenched my teeth, trying to suppress the unwanted desire. I knew that giving in now would be a mistake, a mistake that would surely lead to my demise.

After what felt like an eternity, she finally spoke, her voice a deep, sensual purr. "Hello, Ashen."

Her words broke the spell that she had cast upon me, and I felt my composure crack. I was terrified, but I refused to let her see that. I swallowed hard, my throat dry with fear and anticipation. "Hello," I replied, my voice barely a whisper.

Lyris took a step closer to me, her eyes still fixed on mine. "My name is Lyris," she said formally, her voice as cold as the stone walls around us. "You are my first captive. I have never done what a normal succubus does with a human before. You will be my first."

I felt my heart skip a beat at her words. This was really happening. I was going to die tonight, and there was nothing I could do to stop it. But as she continued to speak, I couldn't help but feel a small spark of hope.

"Do not worry," she said, her voice laced with reassurance. "You will feel immense pleasure during this process and you will not know when you die. Let yourself indulge in the pleasure and I will handle everything else."

I nodded, trying not to show my fear. "Then let's get it over with," I said, my voice cracking slightly out of nerves.

Lyris smiled, but it didn't reach her crimson eyes. "You are braver than most humans, Ashen," she said, using my name for the first time. "But then again, you have no choice, do you? Knowing that you will die after your first time does not sound good, does it?"

I swallowed hard, my throat feeling like it was closing in on itself. "No," I replied truthfully. "But what choice did I have? I got caught stealing food, and now here I am."

Lyris's smile grew wider, and it was in that moment that I realized she wasn't truly empathetic. She was enjoying this, relishing the power she had over me, knowing that my life was in her hands.

"Then you should not have stolen from a shop with connections," she said coldly.

I shrugged, trying to project an air of nonchalance. "Can't blame a guy for trying to survive, can you?"

Lyris's eyes narrowed in anger, but it was only for a moment before she regained her composure. "I purchased you to complete a task my family gave me," she said, her tone becoming more businesslike. "I chose a cheap, healthy man with no connections. I am not interested in sleeping with every man I see like a regular succubus."

I couldn't help but raise an eyebrow at her words. It was almost reassuring that she wasn't like the stereotypical succubus in stories, a creature driven solely by lust. But then again, it didn't change the fact that I was still going to die tonight.

"Let us begin," she said, her voice taking on a finality that left no room for argument. "We will finish as quickly as possible."

With a snap of her fingers, my hands and feet were suddenly tied to the bed, restricting my movements. I struggled against my bindings, but it was futile. Lyris had tied me too tightly, and I was trapped.

She stepped closer to me, her sensual scent making it hard for me to think straight. With another snap of her fingers, my clothes disappeared, leaving me naked and vulnerable. I tried to cover myself with the sheet, but she brushed it aside, exposing me to her hungry eyes.

"You have a good body for a human," she said, her voice filled with curiosity. "Thank you."

I shrugged. "Could be worse."

She chuckled, but her eyes remained cold and distant. "Indeed it could," she said, her attention drifting downward to my exposed body.

Without another word, she untied her own gown, revealing her naked form to me. My breath caught in my throat as I took in her beauty. She was even more stunning naked, her skin pale and smooth, her curves perfect.

She climbed onto the bed, positioning herself between my spread legs. Her eyes met mine, and for a moment, there was something else in them – something that made me think maybe she wasn't as cold and heartless as she pretended to be.

But then, with a flick of her wrist, she was on top of me, her weight pinning me to the bed. Her lips pressed against mine, and in an instant, everything else disappeared. There was only her, her taste, her touch, and the knowledge that this was the last time I'd ever feel anything like this.

I closed my eyes and let myself succumb to the pleasure, trying to savor every moment as I knew it would be my last.

Lyris positioned herself above me, her soft breasts brushing against my chest, her warmth radiating through the thin fabric that separated them. She slowly lowered herself onto me, taking her time as she felt me stretching her tightness. I moaned softly, my hands tracing the curves of her body, my fingertips finding her soft, sensitive spots.

Lyris moved slowly at first, her hips swaying in a sensual rhythm that sent waves of pleasure coursing through both of us. I closed my eyes, completely immersed in the moment, losing myself in the sensations that consumed me.

As they continued, Lyris' pace quickened, her body moving like liquid fire over mine, her moans becoming more and more intense. I responded in kind, my own moans mingling with hers, my hands digging into her hips, my fingers leaving faint red marks.

I felt the drowsiness from her drain trying to pull at me, but I fought it, determined not to lose myself completely in the moment. I focused on the feel of her skin, the taste of her lips, the sound of her moans, and the way her body trembled in pleasure beneath me.

After what felt like an eternity, but in reality was only a few minutes, Lyris suddenly paused, her eyes widening as she looked down at me. "You have lasted much longer than any human should. That is unusual," she said, her voice breathy and filled with surprise.

"I am a man after all," I panted, my own body refusing to follow my mind's commands as I felt the drowsiness finally catching up to me.

Lyris' eyes narrowed slightly, and she realized her draining power was not working properly. She didn't understand why, but she knew she had to fix it quickly if she wanted to complete her task.

She stood up abruptly, her legs shaky from the intensity of their encounter, and moved to the chair beside the bed. She sat down, staring at me with a mixture of confusion and frustration. I watched her, aware of the fact that I should be scared, but my body was too spent to care about anything else.

"Come here and put your mouth on me," Lyris commanded, her voice dripping with desire.

I blinked in surprise. This wasn't what I had expected. I had thought she would at least have me lie down on the bed first and then... I shook my head, banishing the unwanted thoughts from my mind. I wasn't going to enjoy this, no matter what she wanted.

"What?" I asked, my voice betraying my confusion.

"You heard me. You are a slave purchased by my family. You follow the orders of your master," she said, her tone leaving no room for argument.

I narrowed my eyes at her, my anger at her arrogance overpowering my fear for a moment. "You bought me? How dare you!" I spat out, my voice rising in outrage. "I am not your slave! I will not do what you tell me!"

Lyris smiled, her crimson eyes sparkling with amusement. "Oh, but you will," she said, her voice dripping with confidence.

Before I knew what was happening, she was standing over me, her hands gripping my head tightly, and she slammed me to the floor with a force that knocked the breath out of me. I gasped for air, my body aching as I struggled against her iron grip, but it was futile. This creature was stronger than any human could ever hope to be.

"You will do this or your death will not be the peaceful one I promised," she said quietly, her voice laced with menace.

I felt my resolve crumble in that moment, replaced by a mixture of fear and desperation. I didn't want to die, not like this. And so, with a deep breath, I reluctantly moved forward and positioned myself between her thighs.

As I began, my thoughts drifted to my former life, to the life I had left behind. Once more, I cursed my luck for bringing me to this place, this cruel fate. But even as I did so, a small part of me couldn't help but wonder if there was something more to this situation than I originally thought. After all, I had read in countless novels about people transmigrating into new worlds with an accompanying system that gave them untold powers. Here I was, with nothing but my own abilities and a quickly dwindling supply of courage.

And then, just as I was about to give up hope entirely, something unexpected happened. A series of notifications flashed across my vision, revealing a system that had been dormant inside me all this time. Suddenly, my world turned upside down as I realized the potential that lay within me.

[ System Initializing - Exclusive Draining System Acquired ]

[ Bloodline Fragment Detected - Ashborn GOD - Dormant ]

[ Core Ability Unlocked - Soul Drain ]

[ Core Passive Unlocked - Resonance Sight ]

[ Warning - Personality Integration is Active. Ten percent of target's core traits will be absorbed permanently. This cannot be disabled. ]

[ Resonance Recognition - Dormant Instance Located - Lyris ]

I read through the notifications once, my eyes widening in disbelief. He read them again, slower this time, taking in the implications of each line.

'Mandatory and permanent,' I thought to myself, a mixture of disbelief and excitement coursing through me. 'Of course it is.'

With newfound determination, I redoubled my efforts, determined to make the most of my situation. From the corner of my eye, I saw Lyris's face contort in pleasure as I continued my ministrations.

'System,' I thought carefully, 'tell me exactly what Soul Drain does.'

[ Soul Drain - Core Ability. Drains the target's experience, skills during physical intimacy. The amount drained scales with the target's impression of the host and the quality of the Sex. Host receives all drained experience and may convert it to power. The target will feel the drain as intensified sensation and will not immediately understand what is happening. The Drain Quality ca be Recovered by the Target if he keeps Good relationship with Host and if Host wants Target dead then he can Simply drain the Target Completely.]

'So the better I perform,' I thought, with a clarity that felt inappropriate given my current position, 'the more I take from her.'

[ Correct. ]

I assessed the situation with every piece of rational thought I had available. She had purchased me. She had tied me to her bed. She had forced me to the floor. She had every intention of draining me to nothing and walking away with her family obligation neatly completed.

I changed my approach entirely, and the sound she made told me immediately that the change had registered.

"Aahn— what has gotten into you all of a sudden?" she gasped.

I smirked. "In some way, I like this more than you do."

I activated my new ability, draining her experience and skills as my mouth moved in rhythm with hers. I could feel her satisfaction growing, and with it, my own power.

"Wa— wait, what are you doing?" she cried out, her eyes wide with surprise.

"I did what you told me," I replied innocently. "Is something wrong?"

Lyris composed herself, her breathing still labored. "No... no, you're doing fine," she said, her voice strained. "It's just that I can feel your... energy..."

"I'm sorry," I said, my tone full of fake regret. "I just wanted to make sure I did a good job."

Lyris was panting now, her hands gripping my hair tightly. "Get... on... the... bed," she panted, her voice barely audible over the sounds of our passion.

I smirked and did as she asked, climbing onto the bed and positioning myself between her legs. I could feel my body tingling in anticipation of what was to come, as if I was about to walk through an open door into a world of limitless potential.

"You ready for me now, Lyris?" I asked, my voice dripping with sarcasm and amusement.

"Yes," she moaned, her eyes meeting mine in a heated gaze. "I'm more than ready."

And with that, we positioned ourselves and began the second act of our tragic dance, neither of us aware of the consequences that awaited us in the days to come.

after a long time Lyris Exhausted and Slept with me Whole Night.

I woke up first, his eyes immediately drawn to the sight of Lyris sleeping beside him. The cold, formal demon from the night before was nowhere to be seen. She looked younger, softer, her black hair spread out on the pillow, her expression unguarded for the first time. I lay still, simply looking at her, lost in the unexpected tenderness of the moment.

As I watched, a series of notifications appeared in the corner of my vision, detailing the experience and skills I had acquired through Soul Drain. I read through them quietly, a small smile forming on my lips at the thought of gaining such useful abilities.

[ Soul Drain - Target: Lyris - Complete ]

[ Experience Absorbed - 22,675 XP ]

[ Skills Acquired - Charm, Bed Expert, Facial Reading, Lie Detection ]

[ Points Acquired - 20 Points ]

"Those are some pretty useful skills," I murmured softly, my eyes still fixed on Lyris' peaceful form.

Lyris stirred awake at the sound of my voice, her eyes slowly drifting up to meet me. we both stared into each other's eyes for what felt like hours, neither of them breaking the silence. Finally, she spoke.

"You should not be alive," she said, her voice tinged with a mixture of disbelief and wariness.

I shrugged nonchalantly. "I get it."

Lyris frowned at my casual response, her eyes narrowing slightly. "What are you?"

I thought about the Ashborn bloodline, the system, the skills now inside me, the 20 points. I looked at her steadily, my face betraying nothing. "I am nobody. A man with no rank and no name in any registry that matters."

Lyris was quiet for a moment, processing his words. Then something shifted in her expression - the very first tiny crack in her cold composure. Not submission yet. Just the beginning of something she couldn't put a name to and with that, the emotional tension between them broke, replaced by something else entirely - an elusive connection that neither of them fully understood yet. They stared at each other for a long moment longer, each searching the depths of the other's eyes, until finally, Lyris broke the silence.

"I need to prepare for court," she said gruffly, her composure slowly creeping back into place. "Get dressed."

I nodded, my eyes never leaving hers. "Where are we Going?" 

"I have Changed my Mind, I want you alive." Lyris said with her Composed Face looking at me.
