Kain’s First Win
Kain's Dorm Room
The moment Ruby stepped inside, the door closing behind her like a seal of fate, the air grew heavy.
She didn't hesitate.
Her hands were on him in an instant, fingers curling into his shirt, tugging him down into a kiss so fierce it left them both breathless.
Kain responded like a wildfire, his hands sliding along her sides, feeling the taut curve of her waist, the tremble of her chest against him.
"It's about time, right?" he chuckled low against her lips, voice rough.
Ruby whimpered, nodding desperately, her cheeks flushed deep crimson.
"Y-yesss… I waited… so long!"
He grabbed her by the hips, lifting her effortlessly.
She wrapped her legs around his waist, their bodies grinding together with a friction that left no doubt where this was headed.
Kain carried her across the room and threw her onto the bed with a dominance that made Ruby shiver with need.
Her black dress rode up her thighs, exposing smooth, trembling skin.
He walked toward her, pulling his shirt off with one hand, tossing it aside without care.
Ruby's eyes widened, taking in every line of his body, every scar, every taut muscle honed by battle and shadowed by something even darker.
"Kain..." she whispered, voice trembling, reaching out to him.
He caught her wrist, pinning it to the mattress, hovering over her.
"Tell me who you belong to"
"You! Always you!" she cried, arching up toward him, desperate for his touch.
He smirked darkly, pleased, and then captured her mouth again, kissing her until she moaned into him, until she was gasping for air.
His hands slid up her thighs, fingers hooking into the sides of her panties.
With one slow, deliberate tug, he peeled them down, exposing her fully to him.
Ruby whimpered, squirming under his gaze, but didn't look away.
She wanted this.
Needed this.
Kain pressed a kiss to the inside of her thigh, making her cry out softly, trembling like a leaf in a storm.
Then he rose, unzipping his pants, letting them fall to the ground with a heavy thud.
Ruby's breath hitched.
Even though she was loyally devoted to him, and had done him quick favors.
Seeing it up close again in such a passionate moment felt so hot.
"K-Kain..."
Words failed her.
He chuckled low as he climbed onto the bed, caging her beneath him.
"You can still run, Ruby," he murmured, brushing hair from her flushed face.
"But if you stay... you'll never belong to another"
Tears welled in her eyes, not of fear, but of overwhelming devotion.
"I never wanted anyone else," she breathed, pulling him down into a searing kiss.
What followed was nothing less than worship.
Kain moved with slow, agonizing control, teasing her, kissing every inch of exposed skin, taking his time.
He learned every gasp, every whimper, every desperate plea Ruby made.
When he finally pressed into her, inch by aching inch, she clung to him like he was the only real thing in the world.
"K-Kain... ah..." she sobbed softly into his shoulder.
He held her, whispered low promises into her ear, moving with measured, powerful thrusts that left her clawing at the sheets.
Every connection between them deepened, soul to soul, body to body.
There was no space between them now.
No doubts.
No hesitation.
Only the breaking of Ruby's body against Kain's will, over and over again, until she shattered beautifully in his arms.
When she finally collapsed against him, boneless and sobbing his name, Kain gathered her close, cradling her like the most precious thing in the world.
They lay there in silence, Ruby curled up on his chest, her hand lightly tracing the scar over his heart.
"I love you..." she whispered, voice thick with emotion.
Kain kissed the top of her head.
"Good girl," he murmured, his voice carrying a rare softness, reserved for her alone.
The System pulsed faintly in the back of his mind.
[ Soul Bond Complete ]
Kain had claimed Ruby fully, but he still wasn't finished.
Not by a mile.
He looked down again.
Her body, slick with sweat and glowing under the low light of the room, was a vision to him.
Flushed pink, lips swollen from his kisses, thighs trembling from the first brutal, thigh-clapping.
But he needed more.
He shifted his weight, never once breaking full contact, his fingers tracing idle, teasing circles along her ribs, making her shiver.
"K-Kain..." she whimpered, voice ragged.
He leaned down, brushing his lips against her ear.
"You thought it was over?" he murmured, a chuckle in his voice.
Ruby barely managed to shake her head, her body already responding to him again, aching, needing.
Without warning, Kain rolled his hips, grinding into her slowly, deeply, making her moan high and breathless, nails digging into his shoulders.
"Fuck this feels good" he said again, each slow thrust reinforcing the truth like a brand against her soul.
"It's mine, right?"
"Y-yes," she cried, head thrown back, eyes shining with unshed tears of pleasure.
Kain gave her no mercy.
He moved faster now, harder, making the bed frame creak under their combined strength, making the room echo with the wet, sinful sounds of their union.
Ruby's hands were everywhere, clutching at him, desperate to ground herself.
But Kain pinned her wrists above her head with one hand, towering over her like a god made flesh, his white hair falling into wild sex making.
He devoured her mouth with kisses between each punishing thrust, swallowing her cries, her moans, her devotion.
When she came again, it was explosive, her whole body arching off the bed, mouth open in a silent scream of Kain's name.
But Kain didn't stop.
Not even close.
For it was Round Two.
He pulled out slowly, savoring the sight of her trembling, ruined form, only to flip her onto her stomach with a single firm motion.
Ruby gasped, cheeks burning, but eagerly lifted her hips for him, presenting herself fully, a clear message of absolute submission.
"Good girl," Kain said approvingly.
He gripped her hips, guiding himself back to her.
The angle was different now, deeper, rougher, and Ruby sobbed into the pillow, overwhelmed by the pleasure crashing through her.
Kain leaned over her back, teeth grazing the shell of her ear.
"You love this," he rolled his hips, keeping a punishing, relentless rhythm.
"Y-yes! Yes, Kain! I love it!" Ruby sobbed, broken and beautiful beneath him.
Her body surrendered again, rippling around him as another climax tore through her, but Kain only growled low, chasing his own peak with ruthless hunger.
When he finally followed, sinking his teeth lightly into her shoulder as he pulsed deep inside her, Ruby collapsed fully onto the bed, tears of bliss streaming down her face.
But still, Kain wasn't satisfied.
Round Three.
He flipped her onto her back again, seeing the dazed, lovesick look in her eyes.
"One more," he commanded softly, brushing the hair from her damp forehead.
"Kain... I... I can't..." she whispered, weakly protesting.
He smirked.
"You can. For me!"
Ruby whimpered and nodded.
Kain kissed her forehead, tender for a brief, heart-shattering moment, and then entered her again with a slow, devastating thrust that left her breathless.
This time was different.
This time he was gentle, slow, deep, achingly intimate.
He cradled her face, watching her expressions with hungry reverence, memorizing every flutter of her lashes, every gasp, every shudder.
"I love you," Ruby sobbed, voice breaking.
"I know," Kain whispered, pressing his forehead to hers.
They moved together like a single heartbeat, slow and sacred, until Ruby shattered again in his arms, whispering his name like a prayer.
Kain followed seconds later, locking their bodies together as he cummed inside her one last time.
He collapsed beside her, pulling Ruby against his chest, her body trembling but utterly sated.
The two lay there in the darkness, breathing hard, hearts pounding in unison.
Ruby clung to him like he was her whole world.
[ System Message ]
[ Fertility Warning: High Chance! ]
Kain smirked lazily at the message before dismissing it.
'No one gets pregnant in an eroge game'
"Rest, Ruby," he murmured into her hair.
"You earned it!"
Morning After / Saturday
Kain woke slowly, blinking against the pale morning light filtering through the curtains.
The bed was warm, the sheets tangled and messy from the night's battles, but Ruby was gone.
Only the lingering scent of her sweet, faintly floral and full of satisfaction remained.
Kain smirked lazily to himself, stretching his sore muscles.
Three rounds.
A broken bedpost.
A dick finally satisfied.
He sat up, bare-chested, wearing nothing but loose black sweatpants riding dangerously low on his hips, revealing the deep V-cut of his hips and the carved lines of his abs.
'She must have gone to get ready for her "date,"' he thought dryly, running a hand through his wild white hair.
Before he could even get out of bed, there was a knock at his door.
He already knew.
He could feel the familiar idiotic energy behind it.
"Yo, Kain... you up?" Finn's awkward voice called out.
Kain dragged himself off the bed, not even bothering to pull on a shirt.
He opened the door, and there stood Finn, bright-eyed and freshly showered, until he caught a full view of Kain.
Finn's eyes widened like a kid seeing a monster truck for the first time.
Kain's body was practically steaming, his muscles glistening slightly with the afterglow of sweat, his white hair messy and wild, his dark eyes lazy and sharp all at once.
And below that...
Finn's gaze flickered lower.
The outline of Kain's unit under his sweats was not something easily ignored.
Finn's face turned beet red instantly.
"Y-you look like you had a rough night..." Finn stammered, awkwardly scratching the back of his head, eyes desperately trying to stay on Kain's face.
Kain let out a low, lazy laugh, leaning casually against the doorframe.
"You could say that," he said, voice dripping with amusement.
"Heard loud noises, did you?"
Finn nodded, even redder now.
"Y-yeah... the walls are kinda thin, man..."
Kain fought the smirk tugging at his lips.
'Poor bastard'
'Hasn't even kissed Ruby yet'
'Meanwhile, I was balls-deep in her, breaking the damn bed frame'
The thought almost made Kain laugh out loud.
Instead, he just arched an eyebrow and said, "What can I do for you, buddy?"
Finn coughed awkwardly, shifting from foot to foot.
"Uh... well... I'm kinda nervous, man. I just wanted to ask, you know... any advice? How should I... act?"
Kain resisted the overwhelming urge to burst out laughing at the irony.
Instead, he looked at Finn, who genuinely looked terrified, like he was about to be sacrificed to some ancient god of awkwardness.
He clapped a heavy, sweaty hand onto Finn's shoulder, making him nearly collapse.
"Relax," Kain said smoothly.
"Just be yourself. Girls like that stupid, honest side of you. Hold their hands, say cheesy shit. It'll work"
Finn nodded rapidly, drinking in the advice like gospel.
Kain leaned in closer, voice low and conspiratorial.
"And don't be scared to let them fight over you a little. Girls like feeling competitive"
Finn's eyes widened.
"R-really?"
Kain gave him a feral grin.
"Really"
Inside, Kain was laughing his ass off.
'Let them fight over you, huh?'
'Gotta say Finn, some part of me does feel kinda bad for your dumbass'
Finn stepped back, looking a little more confident.
"Thanks, man! You're the best!"
Kain waved him off casually, closing the door.
As soon as Finn was gone, Kain leaned back against the wall, crossing his arms, smirking to himself.
"Poor bastard," he muttered.
His phone buzzed.
A message from Ruby:
Ruby:
Wish me luck on the date! Love you!
I'll make sure to act super sweet!
Kain chuckled darkly, texting back:
Kain:
Yeah, be good.
Don't hurt his feelings.
The System gave a soft ding.
[ New Title: Bed Master ]
"I should get ready"
An Hour Later
The day was perfect.
Too perfect.
Blue skies stretched overhead, the sun gleamed like a golden omen, and the academy courtyard was bustling with students, many casting curious glances toward one group in particular:
Finn, Ruby, and Lyla.
Finn, awkwardly handsome in a casual white shirt and jeans, stood between the two girls, his hands twitching at his sides as he debated whether to hold someone's hand or combust from sheer nerves.
Ruby looked gorgeous, wearing a flowing, soft pink sundress, her hair tied up with a delicate ribbon.
She clung to Finn's right arm, smiling brightly, sweet as spring itself.
Lyla was a little more reserved, dressed in a modest white blouse and a blue skirt, her cheeks dusted a shy pink.
She hesitated on Finn's left, occasionally brushing her hand against his without fully committing to holding it.
From the shade of a nearby tree, leaning against it with devilish laziness, Kain watched.
He wore a simple black T-shirt and ripped jeans, sunglasses low over his eyes, a bottle of water in one hand, the other lazily resting in his pocket.
Yup, if looks can kill, then Finn would have been dead several times over.
Because the inside of his head was chaos.
'Look at this dumbass'
'Fidgeting like a virgin about to touch a boob for the first time'
'Ruby's literally throwing herself at him, and he still looks like he's about to faint'
'Meanwhile, I had her screaming my name into the pillow six hours ago'
He sipped his water lazily, half-listening to their conversation.
Because this day was going to be long and stupid.
The Date
"S-So... where do you guys wanna go first?" Finn asked, voice cracking slightly.
Ruby squeezed his arm.
"Ice cream sounds fun! Don't you think so, Lyla?"
Lyla smiled shyly.
"I-I would like that"
The three of them headed toward the campus town's ice cream parlor, Finn walking like he was escorting two princesses, chest puffed out, doing his best to look confident.
Girls passing by whispered and giggled behind their hands.
"Two girlfriends?"
"Both so cute??"
"Finn's luck is UNREAL!"
Meanwhile, boys passing by gave Finn death stares sharp enough to kill.
And Kain?
Kain just watched it all with a wolfish grin, his eyes glinting under his shades.
'Look at this idiot'
'If only he knew his sweet Ruby calls my name when she climaxes'
'If only he knew that Lyla's heartstrings are already wound around my fingers like a puppetmaster's threads'
At the Ice Cream Parlor
Finn, ever the gentleman, insisted on paying.
He clumsily tried to balance three cones while Ruby and Lyla giggled at him.
"Here! One for you, Ruby, and... one for you, Lyla— Agh!"
Finn nearly dropped Lyla's cone, but she caught it with a small laugh, brushing her fingers against his.
Contact.
Both of them turned bright pink.
Ruby giggled behind her hand, pretending not to notice, even though inside, she was smugly noting points.
'Good. Let Lyla fall harder'
'Kain will be pleased'
The three sat together at a small table outside, eating their ice creams.
Finn, bless his heart, tried to spark conversation:
"So uh... what's your favorite flavor?" he asked Lyla.
Lyla twirled a lock of her hair.
"Strawberry"
Finn smiled brightly.
"Mine too!"
Ruby chimed in, "I like vanilla! But... maybe I should start liking strawberry too, since my precious Lyla-chan does"
Lyla turned pink again.
Kain, who was watching from a rooftop, looked like a goblin king.
Could not hold in the laugh escaping his lips.
"Holy shit, they're so pure it's painful!"
"If I fed them alcohol, they'd probably apologize to each other for thinking dirty thoughts!"
"Meanwhile, I could have Lyla on her knees in under five minutes if I so desired!"
He casually checked the [ Affection Meters ].
[ Ruby. Affection: Max ]
[ Lyla. Affection Meter. 12% → 30% ]
Perfect.
Absolutely perfect.
At the Park
They wandered into a small flower garden, laughing and eating the last of their cones.
Ruby spotted a flower booth and dragged Finn over.
"Let's all wear flower crowns!" she said cheerfully.
Within minutes, Finn had a messy but heartfelt crown of daisies on his head, Ruby wore roses, and Lyla had a crown of delicate lilies.
Kain watched from a bench nearby, arms spread wide across it.
He caught Ruby's eye once, just once.
And she winked at him, subtle, innocent.
No one noticed.
But Kain's heart thrummed with pleasure.
Later, by the Fountain
"Finn..." Lyla said softly.
They stood alone, Ruby conveniently off buying drinks.
Finn turned, confused.
"Yeah?"
Lyla took a deep breath, pink dusting her cheeks.
"Would you... Would you maybe... hold my hand?" she asked, voice tiny.
Finn blinked.
Then, with shaking hands, he took her small, trembling fingers into his own.
Lyla looked like she might pass out.
Finn looked like he might scream.
And in the shadows, Kain leaned forward with a slow, shark-like grin.
'YES. GOOD. HOLD HER HAND, YOU STUPID VIRGIN'
'Fall deeper. Fall harder'
'Make it so when I take her heart, it hurts twice as much'
He closed his eyes briefly, savoring the sweetness of the moment.
By Sunset
The date ended with them sitting by the river, the girls leaning against Finn's shoulders, talking about dreams, hopes, little things.
It was pure.
It was warm.
It was everything that Kain could twist, corrupt, and own in the future.
And as Finn laughed with the two girls, completely oblivious to the spider weaving its web around him, Kain stood from his bench, stretched lazily, and turned to leave.
His work here was done for today.
An Hour Later
The town had started to glow under the sunset, warm gold bleeding into soft lavender skies, the river catching every color like a living mirror.
He walked along a quiet path leading away from the riverfront, hands tucked in his pockets, a slow, satisfied smirk playing across his lips.
[ System Notification ]
[ Ruby – Love: MAX | Lust: 65% → 70% ]
[ System Notification ]
[ Lyla – Love: 30% → 35% | Lust: 10% → 15% ]
He chuckled under his breath.
Poor Finn was too busy blushing at every innocent touch to notice the slow, inevitable ruin barreling toward him.
Kain tilted his head back, letting the evening breeze brush against his face.
'Ruby's already mine in everything but name. Lyla's starting to dream about it'
'Wonder how long before she starts slipping her hands under the covers at night, thinking of me instead of him?'
He laughed slowly, the sound rough and wicked.
He flicked the sunglasses up onto his head, stretching his arms behind him.
'Might reward Ruby later. She's been a good girl'
'Lyla, though... not yet. I want her to be fully devoted to me when we do it'
His fingers twitched at the thought, feeling almost phantom traces of her trembling hand slipping into his.
Sweet.
Delicate.
Breakable.
[ System Notification ]
[ New Subquest – "Strings of the Heart" – Progress 20% ]
He whistled as he walked, casual, light, like a man with nowhere to be and no burdens to carry.
The truth was, he had plans.
Dark ones.
He'd let Finn have a few more dates like today.
Build hope.
Strengthen the delusion.
Let him believe that maybe, just maybe, these two angels had fallen just for him.
And then?
Kain's grin stretched sharply.
He'd take it all.
Rip it out of Finn's hands at the height of his happiness.
Not because he needed to.
Not because it was strategic.
But because it would be beautiful.
The purest kind of ruin.
The Next Day
Kain sat lazily atop the academy's wall, a vantage point only a reckless bastard like him would use.
He swung one leg over the edge, tossing small pebbles down at random passersby.
Below, Finn was talking to Ruby and Lyla again, practically shining.
They laughed at his jokes, leaned in closer when he spoke.
Ruby brushed invisible lint from his shirt.
Lyla tucked her hair behind her ear shyly when he smiled at her.
[ System Notification ]
[ Ruby – Lust: 70% → 75% ]
[ System Notification ]
[ Lyla – Love: 35% → 39% | Lust: 15% → 20% ]
Kain popped a mint into his mouth, crunching down with a snap.
'Faster than I thought'
'Soon, Lyla won't just want to hold his hand'
'Soon, she'll dream about hands far rougher than his ever could be'
He leaned back against the stone, arms behind his head, sunglasses tilted back down over his eyes.
Ruby caught him looking again.
A small smile ghosted her lips, barely noticeable.
She squeezed Finn's arm a little tighter, her body language screaming innocent affection to anyone watching.
But to Kain?
It was her telling him that the plan was going well.
He licked his lips, slowly.
There was no rush.
The best kind of fall was the one you never saw coming until the ground kissed your face.
It would be magnificent.
He could almost taste it.
Almost.
But not yet.
[ System Notification: Ruby – Lust: 75% → 80% (Condition: Craving) ]
[ System Notification: Lyla – Love: 39% → 45% | Lust: 20% → 30% ]
'Soon,' Kain thought lazily, tilting his head as he watched Ruby tuck herself against Finn's side, almost too naturally.
"I should make my way to class now"
He yawned, stretching like a lazy cat before sliding down from the wall in one easy movement.
His boots hit the ground with a soft thud, and he rolled his shoulders back, whistling low under his breath.
[ System Notification ]
[ Lyla. Love: 45% → 48% | Lust: 30% → 32% ]
He flicked his eyes sideways, watching the numbers tick upward even with nothing more than a lingering glance from her.
It wasn't just admiration anymore.
It was longing.
Desire.
Need.
And that, he decided, was enough.
'Time to move'
Not for Finn's sake.
Not for the thrill of the game.
But because Lyla was finally ready to be his.
He shoved his hands into his pockets, striding casually toward the trio as they prepared to head inside.
Ruby noticed him first, of course.
Her eyes lit up, almost imperceptibly, before she masked it with a soft, obedient smile.
He brushed past Finn deliberately, close enough that Finn barely noticed, but Ruby and Lyla stiffened just slightly at his presence.
"Ladies," Kain drawled lazily, sunglasses pushed up into his hair again, eyes gleaming with heat only they could understand.
"You're heading to class, yeah?"
Ruby tucked a strand of hair behind her ear, glancing at Lyla before answering, "Yes. Combat theory"
Kain tilted his head, pretending to consider.
"Ruby. Mind if I steal Lyla for a second?"
He offered the words casually, as if it were no big deal at all.
Ruby smiled, sweet, demure, and nudged Lyla playfully.
"Go on. I'll save you a seat"
Finn laughed a little awkwardly, clearly assuming Kain wanted to tease Lyla about something.
Poor idiot.
He didn't notice the slight tremble in Lyla's hands as she followed Kain a few steps away, her fingers twisting nervously at the hem of her blouse.
Once they were out of earshot, Kain turned slowly to face her, the lazy smirk on his lips softening into something more intimate.
"Been thinkin' about you," he murmured, voice low enough that it sent shivers down her spine.
"You've been thinkin' about me, too, haven't you, Frostbite?"
Lyla's cheeks flushed bright pink, her lips parting like she wanted to deny it, but the system notifications didn't lie.
[ System Notification ]
[ Lyla – Love: 48% → 52% | Lust: 32% → 40% ]
He stepped so close that she had to tilt her head back to meet his eyes.
"You remember we still have yet to do Session Three, right?"
He whispered it like a secret, the weight of the memory heavy between them.
Her blush deepened, a soft, almost inaudible whimper escaping her throat.
"You never got your third lesson," Kain said, brushing a knuckle lightly under her chin.
"You never learned how good it can feel... when you stop holding back"
She swallowed hard, looking everywhere but his face.
But her body betrayed her, leaning in, trembling, desperate, without even realizing it.
[ System Notification ]
[ Lyla – Lust: 40% → 50% (Condition: Need Awakening) ]
Ruby lingered by the academy doors, pretending to chat with Finn, but Kain could feel her eyes on them, silently cheering him on.
'I should buy her a gift later'
He leaned in, letting his breath ghost over Lyla's ear.
"You want it, don't you?" he coaxed, voice all velvet sin.
"You want me to show you what he never could"
Her knees wobbled slightly.
"Y-you're my friend..." she whispered, weak even to her own ears.
Kain chuckled low in his chest, not unkindly.
"You trust me," he corrected.
"And I'd never hurt you"
'Not like he would... when he finds out you were never really his to begin with'
He tilted her chin with two fingers, forcing her to meet his eyes.
"Tonight," he said.
"My room. After lights out"
Ruby would help.
She'd been itching to see Lyla fall, to guide her through it.
After all, Ruby was already his.
She knew how sweet the surrender tasted.
Kain smiled.
Tonight, he would add another to his harem list.
And he wasn't going to let her get a minute of rest.
