She stood still for a long moment, shaking, then finally gave in.
"Fine…" she whispered sharply. "Just stay here. Don't make a sound."
She turned and crept toward the back door.
Sliding it open a crack, she slipped into the house.
Pitch black. The only sound was Minato's snoring, faint through the shut bedroom door.
She unlocked her phone and turned on the flashlight. The beam cut through the darkness as she crept to the family altar room.
She knelt quietly in front of the wooden altar and opened the cupboard beneath it, trembling fingers sifting through the drawers, searching.
The key to the backyard storeroom had to be here. That's where Minato always kept it.
Two minutes passed.
Her breath caught as she finally felt the cold metal key between her fingertips. She closed the cupboard with a soft click and turned—
"Ayaka-chan…"
She froze.
Riku was right behind her, standing inside the altar room.
She hadn't heard him come in. Hadn't even noticed the door open.
Her breath stopped. But somehow, she swallowed the scream clawing its way up her throat.
Gathering every last shred of composure, she grabbed his wrist and yanked him gently but firmly out of the room. Her eyes burned into him.
"Not. A. Sound," she mouthed.
Leading him through the hallway and out the back again, she brought him to the old backyard storeroom—a cramped wooden shed behind the house, used mostly for winter storage and gardening tools.
With trembling hands, she unlocked the padlock and slid the door open.
The air inside was stuffy and smelled faintly of soil and dust.
"Did you bring condoms?" she whispered.
Riku smirked."Nope."
Her face twisted in horror.
"You bastard—"
"Doesn't matter," he interrupted smoothly, stepping closer."You can take the pill, Ayaka-chan."
Before she could respond, he pushed her inside and followed, shutting the door behind them.
The darkness swallowed them.
Riku didn't wait.
His lips crashed against hers, swallowing her weak protest as his hands tugged open the front of her light Japanese pajama robe. It slid down her shoulders and pooled at her feet.
"Riku—wait—"
He turned her roughly and bent her forward, her palms bracing against the cold wall of the shed.
Ayaka squeezed her eyes shut.
She couldn't believe this was happening.
Right here.
Behind her own house.
With her daughters sleeping inside.
The air inside the shed was thick—hot, damp, and heavy with the scent of dust and lust.
Riku didn't give her a moment. He pressed against her from behind, one hand gripping her hip, the other sliding up her bare back.
Ayaka's breath hitched as she felt him push into her—no warning, no pause—just raw, impatient desire.
She bit her lip to suppress the sound, her entire body jerking forward from the force.
Her forehead pressed against the cold wooden wall as she clenched her eyes shut, trying not to think.
Trying not to feel.
But she did.
Every thrust.Every gasp.Every shameful twinge of pleasure knotted with guilt.
The minutes stretched.Seven.Eight.
Her legs trembled beneath her, barely able to hold her up. The quiet squelch of their bodies echoed softly in the cramped room, mingling with her faint, stifled moans.
Then he leaned over her, lips brushing her ear.
"I've fucked so many women," Riku whispered, panting."But you... you're the best, Ayaka-chan."
A shiver ran down her spine—not of pleasure, but of something else. Something darker.
And then she felt him tense behind her.
"Riku—don't… don't come inside!"
Riku didn't listen.
His grip only tightened as he sank fully into her, groaning low against her ear. Ayaka's fingers curled into fists against the wall, her jaw clenched tight, a sob caught in her throat.
It was too late.
When it was over, her body felt hollow. She staggered forward, reaching down to grab her crumpled Japanese pajama robe from the dusty floor, slipping it over her bare shoulders with shaking hands.
She didn't look at him.
Her voice came out cold and bitter, teeth clenched.
"Now get out."
She turned toward the door—but before she could take another step, Riku grabbed her wrist and yanked her back into the shed, slamming the door shut again behind them.
"Ayaka-chan…" he whispered with a grin."I said I was going to have sex with you tonight. I didn't say just once, did I?"
"Bastard—!" she hissed.
Her palm cracked sharply across his face. The sound echoed in the tight space.
Riku only laughed.Not mocking this time—but dark, hungry.
Then he turned her again and bent her over.
And took her a second time.
By the time he left, the sky was still black but beginning to pale at the edges.
It was 4:00 a.m.
He stood in the doorway of the storeroom, stretching.
"Bye, Ayaka-chan," he said, zipping up with a satisfied smirk."See you later."
She didn't reply. She just watched him walk off into the quiet darkness.
When he was gone, she slowly lowered herself to the floor, sitting in the dust and silence of the tiny shed.
Riku's semen was still dripping down her thighs.
But she didn't cry.
She stared at the dirt for a long moment… then reached for her phone with steady fingers.
Dialed.
Riku picked up after one ring.
"Oh? Ayaka-chan? Should I come back?" he teased.
"Meet me tomorrow," she said flatly."I'll send the café's location."
She hung up.
A long breath escaped her lips.
"I'll end it tomorrow," she whispered to herself.
She stood up, wiped the dust from her knees, slipped on her robe properly, locked the storeroom behind her, and quietly entered the house.
Not a single light was on.
Everyone was still asleep.
And in the stillness of her home, Ayaka walked barefoot back to her room, carrying the weight of her sins on silent steps.
