Nahiro slowly pulled down the zipper.
"-kun?"
"Hm? What are you—ah…"
Before he could finish, her mouth was already wrapped around him.
The sudden, overwhelming sensation nearly made him cry out.
Brief—so brief—but enough to leave him breathless.
She'd learned fast. Too fast.
"Riku-kun… mmph… can't talk anymore…"
As he swelled against the confines of her mouth, her words dissolved into muffled sounds. Her small lips were completely occupied.
The moments that followed were a blur of heat and restraint, of hands pressing and breath catching.
Then he hit the edge.
His fingers found her head, pressing down involuntarily.
"Mmm—!"
A soft, choked sound escaped her.
Then warmth. A slow release.
When she finally pulled back, Nahiro was gasping for air, her chest rising and falling in ragged breaths.
She stayed crouched for a few seconds, recovering. Then she opened her mouth, lifted her right hand, and let a thick, pearly white pool fall onto her palm.
She looked up at him with a small, sly smile—like a mischievous child who'd just gotten away with something clever.
Riku nearly lost it on the spot.
[You sense that the mood has reached its peak. To hold back any longer would be an insult to your identity as a man. You decide to turn off the lights, carry her to the bedroom, and—]
The narration didn't even finish.
Knock, knock, knock.
A sharp rapping at the door shattered the atmosphere.
Riku glanced at the clock on the wall.
Seven in the evening.
Who the hell was visiting at this hour?
"Riku-kun! Riku-kun! My sister and I are here!"
Tachibana Emi's voice rang out from the other
Riku's blood ran cold.
Nahiro was still crouched on the floor.
His pants were still undone.
Damn it.
He'd forgotten about this.
Earlier that morning, he'd casually told Emi that his place was big enough—she and her sister could crash there if they needed to.
But tonight?
They were coming tonight?
Riku's apartment only had one bedroom.
Four people sleeping here?
Well…
It wasn't impossible.
He pulled his clothes back into order while Nahiro scrambled to clean up the evidence, her face still burning crimson.
It was her first time doing anything like that. Her first time doing something so… forward.
Just thinking about it made her feel like her head was on fire.
.......
Riku opened the door.
Tachibana Haru and Tachibana Emi stood on the doorstep, each pulling a matching pink suitcase.
"Riku ~kun~"
Emi bent forward slightly as she greeted him, and the view down her blouse was absolutely magni—
She didn't seem to care in the slightest. She looped her arm around his neck, pulling him close like she was about to kiss him right there.
"Emi!"
Her older sister, Haru, frowned sharply, a clear warning for Emi to tone it down.
"Riku-kun," Haru said quickly, "we came to ask for your help."
She straightened, tucking a strand of hair behind her ear.
"My sister and I don't have anywhere to stay right now. She mentioned you said we could borrow a room, so… sorry to impose. Is that really okay?"
[Two. Three. You now have three! You can activate a special mode! You decide to welcome the two sisters into the apartment without hesitation. Tonight, under the cover of darkness, you'll sneak into their bed…]
The narration buzzed in his head again.
"Come in," Riku said, stepping aside.
He ushered the two sisters inside.
As they set down their suitcases, three pairs of eyes swept across the apartment—and landed on Nahiro, who was still tidying up in the living room.
Nahiro froze mid-motion, suddenly self-conscious as she looked at the two girls who'd just walked in.
Emi recognized her immediately.
She was the girl from the hospital yesterday—the one she'd helped change the IV for. The one who'd insisted she wasn't Riku's girlfriend.
And now she was here. In his apartment.
Riku opened his mouth to speak, but Nahiro cut him off.
"I'm just Riku-kun's classmate," she said quickly. "Temporarily staying here…"
She was terrified of what he might call her. Friend? Classmate? Something else?
Better to answer before he could.
At the word classmate , Haru visibly relaxed behind Emi.
Emi, however, gave Riku a skeptical look.
"Riku-kun," she said slowly, "just just a classmate?"
Riku reached out and took Nahiro's hand.
"Let me introduce you properly," he said with an easy smile. "This is Nahiro Yukikami."
He turned to the sisters.
"Nahiro, this is Tachibana Haru—the older sister. And Tachibana Emi."
The three girls exchanged polite nods.
But the air in the room felt thick
Emi stared at Nahiro.
Nahiro kept stealing glances at Riku.
And Haru? Haru was also sneaking looks at Riku when she thought no one was watching.
[You notice the awkward atmosphere is turning the room into a battlefield. You need to do something to ease the tension. Otherwise, how are you supposed to manage three tonight…]
[You decide to clean up and make space for them to sleep. You'll nobly offer to take the couch—and then, once everyone's asleep, you'll sneak into the room and claim all three…]
What the hell?!
This narration was getting out of hand.
"Ahem."
Riku cleared his throat.
"I'll go get things ready. The room's big enough for the three of you. I'll sleep in the living room."
He busied himself with preparing the futons, but the silence was piercing.
From the moment he'd finished speaking, none of the girls had said a word.
Even after he'd laid everything out, the three of them sat in complete, heavy silence.
Riku already knew—this night was going to be anything but peaceful.
......
A short while later, the sound of running water filtered through the bathroom door.
The Tachibana sisters had gone in together to wash up.
The steady rush of water tugged at Riku's thoughts, pulling them somewhere they probably shouldn't go.
[You notice Nahiro Yukikami seems uneasy. This environment isn't letting her relax. While the sisters are in the bath, now is the perfect time to do something special with her…]
Riku glanced at Nahiro.
She was sitting on a stool nearby, fidgeting with her fingers, her thoughts clearly somewhere far away.
"Nahiro? What's wrong?"
"Ah—!"
His voice startled her. She jumped slightly.
"Riku-kun…" She leaned in closer, her cheeks coloring as she lowered her voice. "Could I borrow a change of clothes?"
She'd come with nothing. No bag, no overnight things. Just the uniform she was wearing.
"I can go buy you something."
Nahiro caught his sleeve, holding him back.
"It's late. And we don't have school tomorrow or the day after." Her voice shrank with each word, fading until it was barely audible. "I can borrow yours for now… but… could I try something on first?"
[Try something on? You sense something's off about Nahiro Yukikami. With the Tachibana sisters occupied in the bath, you decide to take her into the bedroom to investigate. If nothing interrupts, something's bound to happen…]
Riku led Nahiro into the bedroom.
Built into the side wall was a closet where he kept his everyday clothes.
He slid the door open.
"Pick whatever you want to wear for now."
He started to turn away.
And then—
Nahiro caught his hand.
Her face was bright red as she looked up at him.
"Riku-kun," she whispered. "Could you stay? …I'm a little scared."
A tiny red heart drifted up from above
Riku glanced at the affection meter.
Nahiro Yukikami, Affection: 98 (Note: You can do anything to her. She absolutely won't resist.)
