"Sunscreen, huh? But aren't you two trying to make me fall for you? Why am I the one putting it on you?" Shichen asked.
"Eh? Well…" Kaguya glanced at Yuzuru for help.
She hadn't really thought that far ahead—she'd just followed Murasame Reine's instructions.
"Explanation. If you put sunscreen on us, Shichen, you'll be able to understand the charm of our bodies," Yuzuru answered calmly.
"Understand the charm of your bodies, huh…"
Shichen smiled at the two of them. "So what you're saying is: I can touch your bodies however I want?"
"Agreement. Shichen can touch wherever he wants—so long as you admit you're attracted to us," Yuzuru nodded.
"W-wait! Wait a second!" Kaguya yelped.
"There are some places you can't touch."
She quickly crossed both arms in front of her chest. The meaning was obvious.
"Is that really okay? Wouldn't it prove your charm even more if I just… couldn't help myself?" Shichen asked seriously.
"T-that's… not…"
"Agreement. Yuzuru has no objection. Kaguya is talking so much because she lacks confidence," Yuzuru cut in, interrupting Kaguya.
"What did you say?" Kaguya bristled—she couldn't stand provocation.
"Who are you saying doesn't have confidence?"
"Question. Then why don't you dare let Shichen touch you?"
"That's because…"
"Mocking. In other words, you don't have confidence."
"Who said I don't dare! I'm not scared of anything! I don't care anymore!" Kaguya shouted.
"Doubt. Are you sure you're not afraid, Kaguya?"
"What's there to be afraid of?! Shichen, come on—put sunscreen on me. Touch wherever you want!"
Kaguya marched over to a white beach mat nearby, then flopped down on it face-first, completely defenseless.
Lying on her stomach like that showed off her beautiful back: snowy-white skin, a delicate line of her spine that made you want to trace it with a fingertip.
Most importantly, her bikini couldn't fully cover her round little butt; the dimples of Venus on her lower back were on full display, and the fabric barely covered the lower curve.
That's the power of a bikini.
"Suspicion. Yuzuru wants to see if Kaguya really dares," Yuzuru said, then lay down on her stomach beside her, mirroring the pose.
The two of them really were identical. From behind, their "fanservice" was exactly the same—only the colors of their swimsuits, inverted from each other, gave contrast and doubled the impact.
There's a reason so many people love twins: double the joy, double the happiness.
"Hmph… I'll leave my back to y-you, then," Kaguya said, voice tight with nerves.
She handed Shichen the bottle of sunscreen from… who knows where she'd hidden it, then flattened herself down again and squeezed her eyes shut.
From his angle, Shichen could clearly see the little tremor at the corner of her eye.
A shy girl trying to act tough… really makes you want to bully her a little.
"Request. We leave everything to you," Yuzuru added, then lay flat as well.
Her voice sounded calm, but Shichen noticed her ears had turned slightly red.
She was just as nervous and embarrassed as Kaguya, yet still poked at her on purpose. Truly good sisters.
In Yuzuru, Shichen saw a bit of Mengmeng's vibe.
He sat down between the two of them, under the shade of a beach umbrella so the sun wouldn't be an issue.
Come to think of it—who'd set up this picnic mat and umbrella rest area out here?
Yeah, he didn't need to think too hard. This was obviously Reine's handiwork.
That woman was basically a perfect housewife.
"Hurry up already," Kaguya complained when she noticed Shichen still hadn't moved.
"What are you so worked up about?"
Shichen looked over their bare backs, then reached out and unfastened the tops of both bikinis, completely baring their smooth backs.
Side by side, the two looked like perfectly carved slabs of white jade.
"Okay, I'm going to start," Shichen said.
"Stop babbling and get on with it!"
"Question. Is Kaguya nervous?" Yuzuru turned her head to look at her, the corners of her lips quirking upward.
"N-nervous? No way!" Kaguya shot back, also glancing at her with a serious expression.
"Is that so… ngh!"
"Mm!"
The two of them suddenly let out soft little sounds, voices sweet and breathy.
Shichen had already pressed his sunscreen-covered hands onto their backs. The cold lotion caught them completely by surprise.
"You're already losing it? It's only going to get more intense from here," he said, moving his hands.
"Ah… ahhn!"
Kaguya immediately let out a cute little cry, her whole body shivering.
"Mm…"
Yuzuru bit her lip and tried to hold it in, though her body had gone stiff as a board.
"Heh. You two okay? Feels pretty chilly, doesn't it?" Shichen asked, watching their reactions.
"N-no, it's fine—keep going…" Kaguya squeezed her fists tight, forcing the words out.
"Agreement. Yuzuru is… also fine…"
"Is that so? Then I'll keep going."
Shichen stopped holding back, focusing on spreading the sunscreen properly.
"Ah—!"
"Mmh—!"
Before long, the two of them couldn't handle his technique anymore and started crying out openly.
The little beach space was filled with their sweet, seductive voices.
Shichen had already set up a barrier so nothing would leak outside—otherwise, anyone passing by would definitely think something extremely indecent was happening.
Neither of them had ever had their bodies touched like this, let alone "massaged" with sunscreen.
Kaguya twisted constantly like she was being tickled, her legs kicking reflexively as she moaned without restraint.
She'd completely lost control—her voice had gone into full "let it all out" mode.
Even Shichen found himself getting a bit overheated just listening.
Yuzuru held out better, but her stifled "Oooh… ah…" sounded even more alluring coming from that normally lazy, flat tone.
Listening to their voices, he finished spreading the sunscreen across their upper backs, then ran his fingers along their spines in one smooth stroke from shoulder to lower back.
Which resulted in—
"Uuuaaah—!"
Their cries overlapped, syrupy and drawn-out, and then they both went limp and stopped moving, mouths only opening and closing as they panted.
They lay sprawled out with arms and legs stretched straight, turning their heads to look at each other with dazed eyes.
"You two okay?" Shichen asked with an innocent expression.
"You're actually asking if we're okay… This is what they call… complete lack of self-awareness, isn't it…" Kaguya muttered.
"Trembling… Calling those fingers 'divine hands' wouldn't be an exaggeration… As expected of Shichen," Yuzuru added.
"What nonsense are you two talking about? Next is the lower half."
Ignoring their stunned faces, Shichen coated his hands with sunscreen again, then moved on to their legs.
Their skin was unbelievably smooth and fine, his palms gliding over them without any resistance or imperfections—like skating over polished ice.
Except their skin was infinitely softer than any ice could be.
Compared to their backs, their legs got a milder reaction. They could handle it better, though when he rubbed the backs of their knees, both of them reflexively kicked up their calves in unison.
Their calves and thighs were unbelievably soft and springy; kneading them really did feel like working dough, and it stopped looking like sunscreen application at all.
But any higher than mid-thigh and their reactions got much sharper, terrified he might touch a "forbidden zone."
Shichen had seen every type of body by now; he wasn't so desperate that he'd just pounce on them.
"Next… is here," he said.
Once he'd finished their legs, he took advantage of their momentary distraction to tug their other bikini pieces off.
A blindingly white view greeted him, glossy and round, with a jiggle like jelly.
"Eh? Wait!" Kaguya yelped, twisting her body away.
"Surprised! That area is off-limits!" Yuzuru echoed, making the same move.
They nearly flashed everything in the process, but Shichen still caught a glimpse of smooth, hairless perfection.
Well, they were spirits. It wasn't unusual.
"Hm? Why?" Shichen asked.
"Why do you think?! We're wearing swimsuits, that part isn't going to get any sun!" Kaguya snapped.
"Agreement. There's no need to apply sunscreen to our butts," Yuzuru nodded.
"Oh, right. I almost forgot. In that case, I guess we're done here," Shichen said, acting like he'd just remembered.
"Phew…" The two looked at each other in relief and sat up.
"Finally done. I thought something was about to go really wrong," Kaguya sighed, thumping her chest.
"Frozen. Kaguya, you…" Yuzuru stared at her.
"What? I…" Kaguya followed her gaze downward—and froze.
Why were there bunnies there?!
She'd forgotten to hook her top back on.
"KYAAA—!"
Her scream rang out, sharp enough to shake the air.
"...Quit screaming. It's not like it's the first time I've seen them," Shichen said, covering one ear.
"Shichen, you—pervert!"
