Her Crimson Temptation
The moment Leon turned from the window—lost in thought under the twin moons' pale glow—the soft creak of his door slicing through the silence made his body tense.
He frowned, already half-turning toward the sound—
And then froze.
His breath hitched.
She was there.
Bare feet kissed the cold floor with each quiet step, her crimson hair tumbling over her shoulders like liquid fire, catching silver moonlight like it was made for her. Her eyes—those deep, haunting scarlet eyes—locked with his. And just for a second, the whole damn world stopped breathing.
"…Rias," Leon whispered. Dry throat. Barely a sound.
And then—he saw what she was wearing.
A black nightgown.
No. Not wearing—that was too tame.
The fabric clung to her like it had no choice, draped over her curves like it'd melted onto her. Her breasts pushed gently against the plunging neckline, soft and full, the thin silk barely keeping them at bay. The slit on the side of her gown climbed high—way too high—exposing creamy, flawless thigh that made Leon's thoughts stumble and crash.
His breath caught again.
Chest tight. Eyes stuck.
What the fuck is she wearing…? No—
What the hell is she doing in here, wearing that?
His heartbeat picked up, skipping like a stone across water. He could feel the heat already rising in his gut, even as he struggled to hold still.
"R-R-Rias…" he stammered, his voice cracking. "What are you doing here… at this hour?"
She lingered at the doorway, hands behind her back, swaying just a little like she was unsure… or like she knew.
Then, slowly, she brought her hands forward. Nervously. Her fingers started fidgeting, twining around each other as her gaze dropped to the floor.
"I…" she bit her lower lip. "I wanted to sleep with you tonight… Daddy."
His brain short-circuited.
He didn't mishear her.
The room was dead silent—but those words echoed like thunder in his skull.
"…What?" he blinked fast, the heat in his face spreading. "Why would you—?"
Her fingers curled tighter, twisting in rhythm with her breath. Then she looked up, voice soft—too soft. "Yesterday… you were sick. You passed out and didn't wake up until today. I was scared. I don't… want to feel that again. If I sleep next to you… I'll know if something happens."
It sounded sincere.
Shaky. Honest.
But her eyes gave her away.
Leon saw it—clear as day. That wasn't just worry. That wasn't just affection.
There was heat in her gaze.
Hunger.
Want.
She was trying to hide it. Badly.
And he remembered.
The old Leon's memories came flooding in—how Rias used to sneak into his bed, whispering excuses like fear or nightmares, curling close like she couldn't live without him. How she adored him. Worshipped him. How she'd look at him like he was the only man who mattered.
Obsession.
The old Leon had always played dumb. Pretended not to see it.
Always turned her away, gently, kindly, like a big brother or father should.
But this Leon wasn't that man.
Do you really think I'm buying that's your only reason, Rias? he thought, eyes narrowing just slightly.
And right then—
[Ding!]
A chime echoed sharp and clear in his head.
[Mission Triggered: Fuck Rias Moonwalker]
[Objective: Make Rias Moonwalker completely yours]
[Reward: Eye of Judge, 20 Black Points, System Shop Unlocked]
[Warning: Failure will disable Touch of Charm]
[Time Limit: 15 Days]
His eyes widened. "The hell—?" he blinked. "Did it just say… fuck her?"
This system wasn't subtle. Not even trying.
He remembered his last point investment—resetting all stats, boosting stamina, agility, vitality. But this reward… "Eye of Judge"? Twenty points? System Shop unlocked?
Way too tempting to ignore.
But still—
He narrowed his eyes. "Isn't this kind of mission… a bit much?" he asked mentally.
[System: All missions are aligned with the host's deepest desires. Stop denying yourself. Accept it.]
"Tch. Bastard system," he muttered inside.
And yet… it wasn't wrong.
Not entirely.
Because part of him wanted this. Wanted her. Badly.
She was standing there, so close, so warm, so fucking tempting—
"Daddy…?" Rias tilted her head, blinking up at him.
He blinked hard. Snapped out of it.
She was studying him, a little confused. "Why are you staring at the air? Are you okay?"
Right.
She couldn't see the interface. Just him—lost in thought.
"…Ah. Nothing, sweetheart," he said, forcing a smile. "Just zoned out for a second."
She kept looking at him like she knew there was more. Like she could feel it. But then—she nodded.
"So…" her voice softened again. "Can I sleep with you tonight? Please?"
He hesitated.
She said it so sweetly. So careful, like she was afraid the wrong tone would make him vanish.
But her eyes...
They burned.
Leon paused, breath caught halfway in his throat. Her voice was innocent, soft as a prayer. But those crimson eyes held something else—heat, hunger, a storm barely restrained. This wasn't just affection. She wanted more.
He inhaled sharply, the corner of his mouth twitching into a faint smile. "...Of course, dear."
Rias blinked.
He saw it instantly—the flicker of disbelief. Like she hadn't expected a yes, not after all the times he'd drawn the line. But then that hesitation melted, and her smile bloomed like dawn breaking through fog.
She lit up. Glowed.
"Really?!"
Leon chuckled, something warm cracking inside his chest. "Really."
She didn't walk—she launched. Arms outstretched, face flushed, heart bursting. She dashed to him, all joy and trembling excitement. And as she moved, Leon couldn't help but notice it.
Her breasts, full and eager beneath the sheer nightgown, bounced with every step. The delicate fabric did nothing to hide the hardened peaks of her nipples, and when she threw herself into his arms, they pressed flush to his chest.
His throat went dry.
She hugged him tight. Clung to him like he was gravity and the world was spinning too fast.
Soft. Warm. Too soft. Too warm.
Her body molded perfectly against his. He wasn't sure whose heartbeat was racing harder.
He cleared his throat, trying to suppress the ache swelling in his pants. "Alright, dear... let's get on the bed."
She giggled, breathy and sweet. "Mm~ okay, Daddy."
They climbed in together. Leon lay on his side, the bed creaking slightly beneath their weight. He tried to keep calm, keep distant, keep cool. But then Rias curled in beside him like she belonged there.
Her curves melted into his side. Her thigh slid over his like silk come to life. Her breath hitched just slightly when she settled in.
Then—
Her ass moved.
Just a little. But enough.
A slow, teasing grind into his hip. Featherlight. Deliberate.
Leon froze.
His cock twitched. Hard.
The nightgown had ridden high, leaving her thighs bare, her ass peeking out with shameless grace. The heat of her skin seeped into him. The scent of her—flowers and something sweeter, something unmistakably hers—filled his lungs.
He clenched his jaw.
Gods, she was soft.
She was fire wrapped in velvet.
"Daddy..."
Her voice—small, shaking, but laced with a darkness that didn't belong in innocence.
"Yes?" he rasped. Holding it together. Barely.
"Can I sleep like this?" she asked, pressing closer, her lips brushing the base of his neck. "It feels... safe."
He swallowed. His throat felt raw. "Sure. Like this."
But she didn't stop there.
Her hips moved again. Slower. Heavier. That ass rolled into his crotch, slow like syrup.
Like she didn't know.
But she fucking knew.
Leon gritted his teeth, cock swelling beneath his pants. It pressed hard against her backside, aching for relief. She gasped, the faintest sound—and instead of pulling away, she leaned in. Her ass cradled his length perfectly.
His restraint cracked.
He triggered Touch of Charm.
The moment it activated, her whole body jerked. A soft, choked sound escaped her lips.
"A-ah..."
Her breath trembled. Her hips twitched.
"My... my body feels weird..."
Leon slid his arm around her waist, pulling her tighter. Her skin burned under his hand, smooth and trembling, alive with want.
He leaned close, his lips brushing her ear. "Rias... do you even know what you're doing?"
She trembled. "I-I just wanted to be close... I love you so much..."
"But you're pressing against me like that," he murmured, mouth gliding down her neck. "You're not a little girl anymore, Rias."
"...I know," she breathed. "I don't want to be... not with you."
Fuck.
That did it.
His pulse thundered. In another life, in another bed, he'd been through more than this. But nothing—nothing—had hit him like this girl did. She made him feel... young. Hungry. Alive.
But he didn't show it.
He couldn't.
He was her anchor now. Her Daddy.
And she was unraveling in his hands.
Slowly, he slid his hand up her belly. Her skin flinched under his touch, soft muscles twitching like she wasn't used to being held like this.
She gasped. Light and shaky.
She didn't stop him.
His hand found her breast. Full and heavy beneath the silk, already stiff at the tip.
He cupped her gently, thumb brushing over her hardened nipple. It responded immediately, tightening even more.
"Nnnh~ Daddy..."
She whimpered. Soaked in need.
He pinched.
She arched back into him, thighs squeezing, her breath going wild.
"Sensitive, huh?" he whispered, lips against her ear. "Your body's telling me everything."
"I-I can't help it... It feels... too good..."
He pushed her nightgown higher. Slid his hand beneath it.
Flesh on flesh.
When his fingers brushed her nipple again—no fabric between them—she moaned like a song.
"Ahn~! D-Daddy...!"
She writhed in his arms, her ass grinding right into his cock.
He groaned.
His other hand wandered, gliding over the curve of her hip, down her ass. He squeezed gently.
Her breath stuttered.
She was moving now. Wanting. Needing. Her leg locked over his, anchoring him to her. Her hips rolled back.
He kissed the back of her neck. She shivered, a soft whimper slipping free.
"Your body's begging," he growled. "You came in here... with no panties, didn't you?"
No answer. She didn't need to.
His hand slid lower.
Between her thighs.
And Damn his finger meet her ... Warm... Wet... slick folds. She shiver under his touch
His fingers brushed her folds—slick, open, begging.
"Rias..."
He bit back a curse. "You're soaked."
Her face was flushed, burning. "Yes. daddy. I... I was wet because of you touch me... daddy"
His breath was ragged by her sexy words. His dick was now stone-hard beneth his pant.
He start stroked her pussy slowly, his fingers teasing her entrance, then gliding up to her clit. Back down. Gentle, rhythmic, worshipful.
She shook. She moan and afer few minute when she feel her oragasm start build.
Her fingers clawed at the sheets.
"D-Daddy...! I... I can't...!"
Her voice cracked. Pleasure spilled through it, naked and raw.
And then she broke.
Her thighs clamped tight, hips bucking. A choked cry tore from her lips.
She came.
Her love juices coated his fingers, slick and hot. But he didn't stop. He continue stroked her pussy through it, slowing only when her body started to sag against his. Then he slowly stop.
Now she was spent. Shivering. Glowing.
He held her close. "Sweetheart..." he whispered, brushing strands of crimsion hair from her face. "You came so hard... just from my fingers."
She whimpered into his chest. Breathless. Shattered.
"I... I wanted this for so long... it's very overhwhelming also, daddy"
He smile and turn her slight just for looked at her face. Flushed skin. Parted lips. Eyes dazed with lust.
She leaned up, lips nearing his. Wanting to kiss him.
But he stopped her. Just barely.
A finger to her lips.
"Not tonight."
Her eyes widened. "But... why?"
He smiled. Half-pained, half-proud. His cock stiil throbbed, still aching. His hand was soaked in her arousal.
But he whispered, "You're not ready, today. But next time... I want everything."
She pouted, lips trembling. "Meanie..."
He chuckled softly. "You'll thank me later."
She pressed back into him. But this time, it was different.
Her thigh fully draped over his. His hand rested between her legs, soaked fingers still nestled against her folds. Her own hand clutched his wrist like a lifeline.
She curled into his chest. Half-naked. Shaking. Her breath evened out slowly.
"Hmph... I'm not going anywhere. So, I'm still sleeping here."
"Good," he breathed into her hair. "Because I'm not letting you go."
And just like that, they drifted into sleep.
Entwined.
Her thigh over his. His hand between her legs.
Desire still simmering like coals under skin.
He looked down at the girl in his arms, her breath soft, steady now.
"Rest well, sweetheart. Today was just the beginning," he whispered.
And the night held them close—tangled in heat, temptation, and something far more dangerous.
