Fuyumi's moan was muffled by the crook of Riku's neck, her nails scraping lightly down his back as her legs locked tighter around his waist.
"Harder," she whispered, voice strained and sweet, like she didn't want to beg but couldn't stop herself. "Don't hold back."
Riku didn't.
Her back arched against the office couch, bare skin brushing cheap leather...as he drove into her with controlled rhythm, measured but relentless. The air was heavy with heat and sweat and the scent of two people tangled far too long. An hour, maybe more. He'd stopped checking the time after the first orgasm.
Fuyumi's jacket lay half-draped over the potted plant by the door. His shirt was still buttoned at the top but open below, her lipstick faint on his collar. The blinds were pulled. The door locked. The only sound beyond the wet slaps and breathless moans was the hum of the building's old air conditioner trying to keep up with their heat.
"Fuck, Riku…" she gasped, clinging to him. "You've been holding back all week...what is this about?"
He didn't answer. Just gripped her hips tighter, thrust deeper, made her feel everything.
He knew what this was about.
Three days.
Three days since that night with Yua...since they'd held each other in that hotel bed, hearts finally confessed, fear finally spoken aloud.
She hadn't kissed him again after that. Hadn't invited him over. No coffee runs, no late-night messages. Just a look, soft, apologetic, restrained.
They both knew that night had been a turning point.
And yet, Yua had pulled back.
She was trying to protect him. She thought she could keep him out of whatever mess Sogimoto had woven around her. But he wasn't going anywhere. Not now. Not when he was this close to the truth.
The Midnight Club. That's what she was afraid of. That's what she was hiding.
He wasn't angry.
Not really.
But if she thought pushing him away would work, she didn't know him at all.
He rolled his hips harder now, drawing another strangled cry from Fuyumi's lips. She clawed at his chest, eyes glazed over, lost in the raw intensity he gave her.
He was using her.
Not emotionally. Not cruelly. She wanted this too, craved the danger, the attention. She liked it when he was unhinged like this.
But today, this wasn't just sex.
It was a message.
Yua was back in the building. Kenji was still home, conveniently out of the way. And Fuyumi had just returned, still flushed from some unknown errand that took her off-grid for the last 48 hours.
Riku knew exactly what he was doing.
He gripped Fuyumi's chin, tilted her head up, and locked eyes with her as he moved inside her with full force now....rhythmic, intense, calculated.
"You want me to finish inside you?" he murmured low, letting the words tease her and echo off the walls.
Her lips parted, breathless. "Yes...please…"
But his eyes weren't on her.
They were looking past her, at the corner mirror.
At the security camera that wasn't technically on...but would be, the moment he flipped the silent switch under the desk.
He wouldn't record it. He wasn't that reckless.
But he knew Yua might check this office later. She knew where Fuyumi had disappeared to.
She'd feel it.
The tension. The air. The scent left behind.
He was giving her a choice.
Stay behind the glass. Or step into the fire.

"You were very fierce today," Fuyumi murmured, her fingers tracing lazy circles on Riku's chest as she curled against him.
Riku smiled, brushing a strand of hair from her forehead. "It's only been three or four days since we last…"
She cut him off with a soft laugh, breathy and satisfied. "Exactly. You've been holding back until now." Her lips curved into something mischievous. "Don't think I didn't notice."
He pressed a gentle kiss to her temple. "I needed to make a point."
Fuyumi's pulse fluttered at the tension in his voice...equal parts pride and something darker. "You succeeded." She lifted her head and looked into his eyes, unguarded desire flickering there. "I like it when you're like this...when you're all controlled heat and purpose. Makes me feel... important."
Riku chuckled, his hand sliding through her hair. "You are important."
A hush settled between them, their breathing slowing in the afterglow. Fuyumi snuggled closer, warm and comforted. "I missed this," she admitted. "Missed you." Her voice softened, vulnerability peeking out. "I don't want to pretend this is just casual."
He tightened his arms around her. "It isn't."
For a moment, the world outside the locked door didn't exist, only the two of them wrapped up in each other's heat and honesty.
Then Fuyumi's eyes widened, a flicker of panic crossing her face. She pulled back slightly, scanning the silent office. In that instant, she remembered: Yua could be watching. Yua, who'd never let them cross this line in her domain.
"Oh..no, no," Fuyumi whispered, voice trembling. "Yua must be angry. She never allowed us to… not here."
Riku caught her gaze and gave her a reassuring squeeze. "We'll clean up. No trace."
But Fuyumi's heartbeat thundered in her ears as she realized the risk they'd taken, and the choice Yua now faced.

Yua's Office — Afternoon
The office was silent, lit only by the soft glow of the monitors. Yua sat alone at her desk, one leg crossed over the other, her eyes fixed on the security feed playing on the screen. The image was muted, but it didn't need sound...she could read every movement, every touch, every expression.
She didn't look away.
Not out of jealousy.
Not out of rage.
Her fingers rested against her lips, her face unreadable. Inside, however, a storm was brewing, not the violent kind, but the kind that wore you down with persistent questions.
"Why am I hesitating?"
The question echoed in her head like a slow drumbeat.
"Do I want him?"
Yes.
"Do I want to be in her place?"
God, yes.
So what was stopping her?
Pride? Guilt? Fear?
She leaned back slowly, her gaze still locked on the screen even as the video looped again. The way Riku touched Fuyumi… it wasn't just sex...it was deliberate. Like he was trying to get her attention.
And he had.
Her hand reached for the phone on her desk, fingers hovering for a moment before she tapped the screen and scrolled to a number she barely used anymore. A number that once meant everything… and then meant nothing.
She hesitated for just a breath.
Then she tapped Call.
The line began to ring.
And Yua… didn't blink.
