《Level Up in Lust: An Isekai LitRPG Erotic Adventure》


 The Fall

    Leon Carter never expected to die in a traffic accident. He wasn¡¯t a smoker, didn¡¯t drink to excess, and he¡¯d only been awake for two hours when his life was torn away from him. The coffee in his hand splashed across the dashboard as the truck¡¯s wheels screeched, metal grating against metal with a sound that made his teeth ache.


    And then nothing.


    No flash of light, no heaven, no hell. Just a dark, empty void.


    A suffocating blackness that stretched out far beyond what he could see, feel, or understand. Leon had always thought that dying would feel like something¡ªpain, a flash of warmth, maybe even a whisper of the beyond¡ªbut nothing had prepared him for the numbness of it all.


    Then, an intrusive voice broke through the silence.


    "Are you prepared?"


    The voice wasn¡¯t loud, yet it reverberated through his skull, ringing like the chime of a bell. There was no shape, no source, no body that could have been speaking to him. Just that voice.


    Leon tried to respond, but his mouth wouldn¡¯t move. His mind, though, was as active as ever.


    "Prepared for what?" he wanted to ask, but his thoughts fell flat, suffocated by the crushing void.


    "To be reborn," the voice replied, clear as day, as though Leon had never been dead in the first place. "To become something more. Something greater."


    Leon¡¯s thoughts turned to panic. He tried to reach out, tried to scream, but it was as if his consciousness was trapped in a vacuum. He couldn¡¯t feel his limbs, couldn¡¯t feel anything except the crushing weight of the void. His body, if it still existed, was light years away. He didn¡¯t even know if he had a body at all anymore.


    He was, for all intents and purposes, a thought in an empty space.


    "Who¡­ who are you?" Leon thought, his mind desperate to find something¡ªanything¡ªthat could make sense of this. But the voice didn¡¯t answer him.


    The void stretched on, making him wonder if he was alone forever. Was this death? The absolute end? Was this the fate of everyone who wasn¡¯t fortunate enough to get a last-minute miracle?


    Just as despair threatened to swallow him whole, the void cracked.


    A flash of light¡ªbrilliant, blinding¡ªcut through the darkness. It was like staring directly at the sun, but it didn¡¯t hurt. No, it was more like it felt like something he had been missing. A part of himself he had forgotten.


    You could be reading stolen content. Head to Royal Road for the genuine story.


    And then, it all snapped into focus.


    Leon found himself standing on solid ground, surrounded by a sprawling, unfamiliar landscape. He blinked, taking in the sight of a lush green forest, the rustling of leaves, the faint, cool scent of the air. He could feel his feet on the ground, his chest expanding with a deep breath.


    A sound, a distant hum, pulsed through the air, vibrating against his skin like a heartbeat. The world was alive.


    "You¡¯ve been chosen."


    The voice again, though it was now softer, almost playful.


    Leon turned, his heart racing as his hands instinctively searched for any weapon or familiar item. Instead, his fingers brushed against something strange¡ªa glowing panel materialized before his eyes, shimmering in front of him like a holographic screen.


    Welcome, Leon Carter.


    His mind raced. His name, his full name¡ªit was the first time he¡¯d heard it since the accident. The first sign that he was still here. But the screen continued.


    Your class: Hero of Eros.


    Skill unlocked: Eros System.


    Objective: Level Up through intimacy and gain power.


    The words almost didn¡¯t make sense. He stared at them, blinking again, hoping they¡¯d disappear or change into something familiar. But they didn¡¯t.


    What the hell is this? Leon thought, his pulse quickening.


    The screen flashed, and a new message appeared.


    You have no choice but to accept your fate. You will be tested. You will build relationships, gain power, and uncover the truth behind your abilities.


    "Wait... this is... is this real?" he asked aloud, though he wasn¡¯t sure who to speak to. The voice wasn¡¯t responding, and he felt, for the first time, entirely alone.


    Except¡­ it wasn¡¯t quite alone. As Leon stood there, confusion clouding his thoughts, a rustling sound came from behind him. He turned sharply, a hand instinctively reaching for something¡ªanything¡ªbut found nothing but empty air.


    Then, she appeared.


    A woman stepped from the trees, her presence almost surreal in the way she moved, like she was gliding. Her long, silver hair framed her face, glowing with an ethereal radiance. Her eyes, a brilliant green, met his with such intensity that Leon took an involuntary step back. She looked¡­ like something out of a dream.


    But the words that spilled from her lips weren¡¯t dreams.


    "You¡¯ve arrived," she said, her voice a melody, soft yet commanding. "Welcome to our world, Hero of Eros."


    Her gaze flickered to the glowing screen, her expression unreadable. "You must prove yourself," she continued, her tone shifting from warmth to something darker. "But remember, power in this world is earned through... connection. Intimacy. You will find your strength through others."


    Leon¡¯s stomach twisted at the words, but it wasn¡¯t fear¡ªsomething about her presence was... alluring. Magnetic.


    Before he could respond, the air around him shifted. The glowing screen flared again, and a new set of instructions appeared.


    Quest started: Build a Harem. Gain power through intimacy.


    Leon stared at the quest prompt, the weight of its implications sinking in like a stone in his stomach. It was absurd, but somehow, it also felt... right.


    "Who are you?" he asked, his voice shaking slightly.


    "I am Lilia Everhart," she said, a smirk tugging at the corner of her lips. "And you, Leon Carter, are about to learn just how powerful you can become."


    Her words hung in the air, heavy with promise and something darker¡ªsomething he couldn¡¯t quite place.


    "Get ready," she continued, her smile widening. "This is only the beginning."


    And Leon Carter, a man who had once been ordinary, found himself standing on the precipice of something extraordinary¡ªand terrifying.


    He had been reborn. The question was: could he survive in this new world?

 Baptism by Fire

    Leon barely had time to process what Lilia had said before she moved. The elf¡¯s emerald eyes locked onto him with unsettling intensity, and in the space of a single breath, she raised a hand. Arcane symbols flickered to life around her, glowing with an eerie, pulsating energy. The air between them thickened, charged with something unnatural.


    Leon took an instinctive step back, heart hammering. "Hey, hold on! What¡ª"


    A blast of wind surged forward, slamming into him with the force of a charging bull. He hit the ground hard, the impact knocking the breath from his lungs. Dirt filled his mouth as he gasped, rolling onto his side. Every nerve in his body screamed, not from pain, but from the sheer wrongness of the situation.


    Lilia stood over him now, her face unreadable. The glow from her magic faded, but the tension in the air remained. "Good. You¡¯re not dead."


    Leon coughed, wiping grit from his lips. "Not dead? What the hell was that for?"


    Her expression didn¡¯t change. "You need to learn quickly."


    Leon pushed himself up, his limbs still shaky. "Learn what? How to get thrown around by a magical elf?"


    "You¡¯re the Hero of Eros." Her voice was calm, but there was an edge to it. "If you can¡¯t handle a little pressure, you won¡¯t last long in this world."


    A bitter laugh slipped from Leon¡¯s lips. He wasn¡¯t even sure why he was laughing¡ªmaybe it was the absurdity of it all. A day ago, he was just another guy, slogging through life. Now, he was apparently some kind of "hero," getting ragdolled by an elf in the middle of a forest.


    He exhaled, forcing his thoughts into order. "Alright. Fine. You¡¯ve made your point. Now, maybe instead of knocking me on my ass, you can explain what¡¯s actually going on?"


    Lilia studied him for a moment, then, to his surprise, nodded. "Stand up."


    He did, brushing dirt from his clothes. As he straightened, the glowing panel from before reappeared in front of him. It still looked like a video game interface, shimmering in the air.


    Quest Updated: Survive Your First Test


    Objective: Defend Yourself Against Lilia Everhart.


    Leon frowned. "You¡¯ve got to be kidding me."


    "Magic, combat, and¡­ other skills will define your survival here," Lilia said, taking a step back. "The Eros System is powerful, but it doesn¡¯t mean anything if you die before learning how to use it."


    Leon¡¯s brain latched onto those words. Other skills. The way she said it wasn¡¯t subtle. But before he could dwell on it, she raised a hand again. Another flicker of energy coiled around her fingertips, crackling with raw potential.


    This narrative has been unlawfully taken from Royal Road. If you see it on Amazon, please report it.


    He had a choice: stand there like an idiot and get blasted again¡­ or fight back.


    His eyes darted to the panel. His stats were displayed now, though most of them were low. Strength, Dexterity, Intelligence¡­ all basic. But at the bottom, one thing stood out.


    Skill: Eros Infusion (Level 1) - Enhances all abilities when engaging in physical intimacy.


    Leon grimaced. "Well, that¡¯s not exactly helpful right now."


    Lilia¡¯s fingers snapped, and another blast shot toward him. Instinct took over. He dove to the side, hitting the ground in an awkward roll, narrowly dodging the attack. The burst of magic struck a tree behind him, leaving a scorched mark on the bark.


    "Good," Lilia murmured. "You¡¯re not completely hopeless."


    Leon¡¯s breath came in fast, shallow gulps. This was real. This wasn¡¯t some dream or hallucination. He could feel the weight of his body, the strain in his muscles, the heat radiating from where the spell had nearly grazed him. His survival instinct flared, cutting through the lingering disbelief.


    Fine. If this was real, then he needed to start acting like it.


    He straightened, focusing. The Eros System¡ªwhatever the hell it really was¡ªhad given him an ability. Even if the description was vague, it had to mean something.


    A thought occurred to him. If his abilities were linked to intimacy¡­ then maybe even contact could trigger something. It was a long shot, but at this point, he was out of options.


    Lilia¡¯s next attack was already forming, but Leon didn¡¯t wait this time. He lunged forward, closing the distance between them before she could react.


    The moment his fingers brushed against her wrist, something clicked.


    A surge of warmth spread through him¡ªno, not just warmth. Power. It wasn¡¯t like the rush of adrenaline he¡¯d felt before; this was different. It was like a floodgate had opened, energy pouring into his body from the brief touch alone. His senses sharpened, his heartbeat steadied. The world around him became painfully clear.


    Lilia¡¯s eyes widened. "What¡ª"


    Leon moved without thinking. He twisted her arm just enough to throw her off balance, stepping behind her. She stumbled slightly, and for the first time, her composure cracked.


    She wasn¡¯t expecting that.


    Leon¡¯s grip on her wrist tightened, and the glow of the interface shifted.


    Eros Infusion Activated: Strength +2, Reflexes +2, Combat Instincts Engaged.


    His body reacted before his brain could process the words. He pivoted, sweeping her legs from under her. Lilia hit the ground with a startled sound, her silver hair fanning out beneath her.


    Silence.


    Leon breathed hard, half-expecting the interface to tell him he¡¯d just made a terrible mistake. Instead, the notification simply updated.


    Test Complete. +100 Experience Gained.


    Lilia blinked up at him, her expression unreadable. Then, to his complete shock, she laughed.


    It wasn¡¯t a mocking laugh. It was amused, maybe even impressed.


    "Well, well," she murmured. "You might actually have potential after all."


    Leon exhaled, finally stepping back. The power boost from his skill faded, leaving him slightly lightheaded. "Glad to hear it. Now, seriously, what the hell is going on?"


    Lilia sat up, brushing dirt from her sleeve. "Fine. I¡¯ll explain properly this time."


    She met his gaze, her smirk returning. "But first¡­ we need to find you some allies. You¡¯ll need them."


    Leon didn¡¯t argue. He didn¡¯t know what this world had in store for him, but one thing was clear¡ªhe wasn¡¯t going to survive alone.


    And if the Eros System was as powerful as it seemed¡­ he had a feeling things were only going to get more complicated from here.

 The Road to Power

    Leon walked in silence as Lilia led him through the dense forest, his mind racing with everything that had happened. The Eros System. A world where power was gained through intimacy. Magic. Combat. The weight of it all pressed against his skull like a vice, but he pushed it aside. He had already died once¡ªnow, he was alive again, and whether he liked it or not, he had to play by this world¡¯s rules.


    Lilia had relaxed since their fight, though she still carried herself with an air of quiet authority. She moved like a shadow, effortlessly navigating the uneven ground. Leon had already tripped twice. He wasn¡¯t used to this¡ªwalking through the woods without a path, dodging low-hanging branches, feeling the ache in his legs from the terrain. His old life had been spent in front of screens, not trudging through untamed wilderness.


    "You¡¯re struggling," Lilia said without looking back.


    Leon grunted, brushing off a thorny vine that had caught on his sleeve. "Yeah, well, I wasn¡¯t exactly dropped into this world with hiking boots and a survival guide."


    Lilia¡¯s lips quirked, but she didn¡¯t slow her pace. "You¡¯ll adjust."


    He wanted to argue, but she wasn¡¯t wrong. His body already felt stronger than it had when he first arrived. He wasn¡¯t gasping for air, and his legs didn¡¯t feel like they were about to give out. Was that part of the Eros System too? A passive enhancement? He glanced at his hands, half-expecting to see something glowing beneath his skin, but there was nothing.


    The two walked for another few minutes before Lilia finally stopped.


    "We¡¯re close."


    Leon didn¡¯t know what she meant at first, but then he heard it¡ªthe unmistakable sound of rushing water. He followed her through the last stretch of trees and found himself staring at a river, its surface shimmering under the fading light.


    Lilia knelt near the water¡¯s edge, cupping a handful and bringing it to her lips. She drank without hesitation, then motioned for Leon to do the same.


    He hesitated. "Is this even safe?"


    Lilia arched an eyebrow. "What, are you expecting a water purification system?"


    Leon sighed and knelt beside her. The water was shockingly cold against his hands, but when he drank, it was crisp, refreshing. He hadn¡¯t even realized how thirsty he was.


    As he wiped his mouth, a rustling sound caught his attention.


    Lilia¡¯s body tensed immediately. "We¡¯re not alone."


    Leon turned, scanning the trees. The forest had gone eerily quiet, the distant chirping of birds vanishing in an instant. His gut twisted. He might not have been a warrior, but he had played enough games to recognize this feeling.


    Something was hunting them.


    The first movement came from their left¡ªa blur of dark fur and muscle. Leon barely had time to react before the creature lunged.


    A wolf, but not like any he had seen before. It was too big, easily the size of a small horse, its eyes glowing with an unnatural red light. Its claws raked the air as it sailed toward him.


    Leon¡¯s body moved before his brain did. He dropped, rolling to the side just as the beast landed where he had been standing. Dirt exploded beneath its paws. It snarled, sharp fangs glinting.


    Love this story? Find the genuine version on the author''s preferred platform and support their work!


    Lilia was already moving. A ball of fire burst to life in her palm, and with a flick of her wrist, she sent it hurtling toward the wolf. The beast dodged, but the fire singed its side, making it howl in pain.


    Leon¡¯s heart pounded. He had no weapon, no real combat experience, and no idea what to do. The Eros System had given him power, but he couldn¡¯t exactly seduce a damn wolf.


    The creature lunged again. This time, it went for Lilia.


    She jumped back, but her footing slipped on the damp ground. Leon saw it happen in slow motion¡ªthe moment her balance wavered, the split second where she was open.


    He didn¡¯t think. He reacted.


    Leon threw himself forward, crashing into the wolf¡¯s side. It was like tackling a brick wall, but his momentum was enough to send it off course. The beast stumbled, claws tearing into the dirt instead of Lilia¡¯s flesh.


    Pain flared in Leon¡¯s shoulder from the impact, but he ignored it. Adrenaline surged through his veins, drowning out everything else.


    Lilia was back on her feet, her hands glowing with power. "Move!"


    Leon barely had time to throw himself away before a second fireball shot past him. This one hit its mark, striking the wolf directly in the face. The creature howled, flames licking at its fur. It thrashed violently before finally collapsing, smoke rising from its smoldering body.


    Leon lay on the ground, breathing hard.


    Lilia stood over the corpse, watching it for a long moment before exhaling. "Not bad."


    Leon let out a dry, breathless laugh. "I just tackled a monster wolf. What part of that was good?"


    "You didn¡¯t hesitate," she said simply. "That¡¯s more than I expected from you."


    Leon pushed himself upright, wincing as his body protested. His interface had appeared again, glowing faintly.


    Battle Completed. +200 Experience Gained.


    Eros Infusion Skill Progress: 10% to Level 2.


    He frowned at the last part. Even though he hadn¡¯t used his ability directly, it had still progressed. Did physical combat somehow tie into it too? Or was it because he had saved Lilia?


    Lilia turned to him, her gaze assessing. "We need to keep moving. That wasn¡¯t the only one."


    Leon¡¯s stomach tightened. "You mean¡ª"


    A second howl echoed through the trees. Then another.


    Lilia swore under her breath. "They¡¯re hunting in a pack."


    Leon wanted to scream. He had just fought his first monster. Now there were more?


    Lilia was already moving. "Come on!"


    Leon didn¡¯t need to be told twice. He sprinted after her, his body protesting every step. The forest blurred around him as he ran, branches whipping past. The howls were getting closer.


    Lilia suddenly veered left, grabbing his wrist and yanking him behind a cluster of thick trees. She pressed a finger to her lips, signaling for silence.


    Leon¡¯s pulse thundered in his ears as he crouched beside her. His lungs burned. He barely dared to breathe.


    The wolves emerged moments later. There were three of them, each as massive as the first, their red eyes scanning the forest. They sniffed the air, their ears twitching.


    Leon¡¯s mind raced. They couldn¡¯t fight all three at once. He needed an edge.


    Then it hit him.


    The Eros System.


    Lilia had reacted when he touched her before. He had gained power from it. What if there was more to it?


    He glanced at her, his heart hammering. It was a long shot, but he had no choice.


    He reached out, brushing his fingers against her arm.


    A shock ran through his body, a sudden surge of energy. It wasn¡¯t just a stat boost this time¡ªit was something deeper. His senses expanded, the world sharpening around him. He could feel the wolves, sense their movements before they even made them.


    Lilia gasped softly, her body going rigid for a moment. Then she looked at him, realization flickering in her eyes.


    "You¡ª"


    Leon didn¡¯t let her finish. He moved.


    The first wolf lunged just as he did. But this time, Leon was faster. He twisted, grabbing a broken branch from the ground and driving it into the beast¡¯s throat. It let out a strangled yelp before collapsing.


    Lilia reacted instantly, launching another fireball at the second wolf. It exploded on impact, sending the creature sprawling.


    The third hesitated, sensing the shift. Then it turned and vanished into the trees.


    Silence fell.


    Leon panted, his entire body humming with energy. He looked at Lilia, who was staring at him.


    "You just¡ª" she started, then stopped, shaking her head.


    Leon swallowed. "I think I¡¯m starting to understand this system."


    Lilia¡¯s expression was unreadable. "Then we need to find out just how far you can push it."


    Leon exhaled, his hands still shaking. He didn¡¯t know what was coming next, but one thing was clear.


    This world was testing him.


    And he was going to survive.

 Forging Strength

    Leon woke to the sharp sting of morning air against his skin. His muscles ached from the battle the night before, but the dull pain only served as a reminder¡ªhe was alive. Alive in a world that demanded strength. The scent of damp earth and morning dew filled his lungs as he pushed himself upright, stretching the stiffness from his limbs.


    Lilia was already awake, standing by the river, staring into the water as she ran her fingers through her silver hair. She didn¡¯t acknowledge him at first, but Leon could tell she was thinking. Calculating. She had seen what he was capable of¡ªwhat the system could do.


    "You¡¯re up," she finally said, her voice carrying over the quiet rush of the river.


    "Hard to sleep when your whole body feels like it got hit by a truck," Leon muttered. He rolled his shoulder, wincing at the soreness. "So, what¡¯s the plan?"


    Lilia turned, crossing her arms. "We train."


    Leon exhaled. He¡¯d expected that answer, but hearing it made his body protest all over again. "Right now?"


    "Right now."


    He groaned but stood up, brushing dirt from his pants. "Alright, drill sergeant. Where do we start?"


    Lilia wasn¡¯t alone in her decision. They weren¡¯t the only ones in this world seeking power. A group had gathered near the clearing just beyond the treeline¡ªfigures Leon recognized.


    Sasha Moonveil, the mischievous catgirl rogue, leaned lazily against a fallen log, flicking a dagger between her fingers with effortless skill. Ravena Blackfang, the demon warrior, stood with her arms crossed, her blood-red eyes locked onto Leon like a predator sizing up prey. Princess Evelyn Brightvale, in her polished silver armor, adjusted the strap of her gauntlet, radiating regal confidence.


    And then there was Freya Ironclad, the dwarven blacksmith. She had a thick braid of fiery red hair and a sturdy frame that looked like she could forge weapons with her bare hands if she wanted to. She cracked her knuckles, the sound like breaking stone.


    "You¡¯re late, boy," Freya said, her voice deep and rough. "We¡¯ve been waiting."


    Leon blinked, glancing at Lilia. "Uh¡­ you invited a whole party to kick my ass?"


    Lilia smirked. "Something like that. If you want to survive in this world, you¡¯ll need to learn how to fight properly¡ªnot just rely on lucky instincts and bursts of power."


    Leon rubbed his temples. "This is gonna hurt, isn¡¯t it?"


    Reading on Amazon or a pirate site? This novel is from Royal Road. Support the author by reading it there.


    Ravena grinned, showing sharp teeth. "Oh, absolutely."


    Sasha purred. "But maybe you''ll enjoy it."


    Leon groaned again.


    They started with endurance. Lilia had them running laps around the clearing, weaving through trees, ducking under branches, and leaping over roots. Leon, to his own surprise, found himself keeping up. His body adapted quickly, the Eros System enhancing his stamina. He wasn¡¯t sure if it was just a passive buff or if it was tied to his growing connection with the others, but he wasn¡¯t complaining.


    After the run came combat drills.


    Freya tossed him a wooden sword, its weight surprisingly hefty. "Let¡¯s see if you can hold your own, lad."


    Leon barely had time to adjust his grip before Freya came at him. Despite her shorter stature, she was fast. Her training sword lashed out, and Leon barely deflected in time. The impact sent a shock up his arms.


    "Too slow!" Freya barked.


    Leon gritted his teeth, stepping back as she advanced. He tried to counter, swinging toward her side, but Freya sidestepped with practiced ease.


    Damn, she¡¯s good.


    He adjusted his stance, tightening his grip. He had no illusions about winning¡ªthis was about surviving. About learning.


    Freya tested him, landing sharp strikes against his arms, his ribs, his legs. He blocked where he could, absorbed the hits where he couldn¡¯t. Each impact left a lingering ache, but his body was adapting.


    Then, something clicked.


    Leon sidestepped a heavy strike and countered¡ªhis wooden sword striking Freya¡¯s exposed side. It wasn¡¯t enough to hurt, but it was enough to make her pause.


    Freya grinned, tapping her blade against her palm. "Not bad, boy. You¡¯re learning."


    Leon exhaled, wiping sweat from his forehead. He turned to Lilia. "How does this tie into my system? There¡¯s gotta be more to it than just training the old-fashioned way."


    Lilia studied him, then nodded. "Sasha, come here."


    The catgirl sauntered over, tail flicking. "Oh? Are we finally getting to the fun part?"


    Leon felt a flicker of something as she drew close. The same sensation he had felt when he touched Lilia before¡ªthe energy exchange.


    Lilia gestured between them. "Hold his hand."


    Sasha¡¯s grin widened. She reached out, fingers lacing through Leon¡¯s. The moment their skin touched, power surged through him. His vision sharpened, his heartbeat steadied, his muscles hummed with newfound energy.


    A notification flashed in his mind.


    Eros Infusion Activated: Partner Bonus¡ªAgility Boost (15%)


    Leon blinked. "Whoa."


    Sasha giggled. "Oh, I like this system of yours."


    Lilia ignored her. "Now, fight Freya again."


    Leon didn¡¯t question it. He turned back to Freya, gripping his sword. This time, when she lunged, he moved without hesitation. He dodged, sidestepped, countered. His reactions were faster, his strikes sharper.


    Freya grunted as he slipped past her defenses, landing a solid hit against her shoulder. "Well, damn."


    Lilia nodded, satisfied. "Your system isn¡¯t just about intimacy. It¡¯s about connection. The closer you are to someone, the more benefits you gain."


    Leon exhaled, his mind spinning. So it wasn¡¯t just sex¡ªit was bonds.


    "That means," Lilia continued, "the stronger your relationships, the stronger you become."


    Leon looked at the gathered women¡ªthe warriors, mages, and rogues standing with him.


    He wasn¡¯t alone in this.


    He was building something.


    Sasha smirked. "Guess that means we need to get really close, huh?"


    Leon sighed. "This is gonna be a long training arc."


    And with that, the real work began.
