«Would you carry this box to my bedroom? It's too, too, too heavy! I can't do it!»
Yuzu clings to Hakuto, whining like a brat, as if the box weighed a ton. The theatrics are unnecessary—Hakuto would've helped anyway—but that's just Yuzu.
She walks ahead, leading the way.
No matter how hard he tries not to stare at her butt, he fails miserably. The ridiculously short and tight blue shorts Yuzu's wearing only make her small but firm butt even more irresistible—and to make it worse, she walks with a deliberate sway, as if trained to show it off.
Hakuto cares about his father and respects him, but on a personal level, he doesn't think much of him. He basically sees him as half a pervert — not exactly a rare opinion. That's why Hakuto tries his best to act like the complete opposite of his old man.
~I'm not like my dad. I'm not like my dad. I'm not like—damn it, I looked again...!~
Still, he's just a boy, and avoiding Yuzu's butt entirely is a mission far beyond his limits.
«Oh, this will be your bedroom,» Yuzu announces, stopping in front of one of the many doors along the hallway. It's a white door with a very detailed drawing made with a black marker of a...
«Wh-Why is there a huge dick drawn on my bedroom door?!»
«Huh? I don't get what's so weird about it...» Yuzu says, pressing a finger to her lips with a fake-innocent look. «Don't you like how I drew it?»
«It's not about how you drew it—IT'S A HUGE DICK ON MY DOOR!»
«Ugh, you're so picky... I even drew it big! You should be happy your little sister thinks so highly of you!»
«Oh yeah? And how do you figure that?»
There's a hint of pride in Hakuto's voice… after all, Yuzu's words would flatter any boy.
A big smile spreads across Yuzu's face. «From the fact that you're Shin's son.»
«A-And what do you know about how big my dad's thing is?!»
«Isn't it obvious?»
Yuzu's smile grows even wider, and Hakuto starts to sweat cold.
~Please… don't say what I think you're about to say…~
«Your dad is very nice, but to impress my mom, it takes more than just being nice, if you know what I mean... He must have some pretty impressive hidden qualities down there. And since it's a hereditary trait...» Yuzu adds with a wink.
Hakuto lets out a long sigh of relief at those words. For a moment, he had feared the worst.
Two doors down, on the same side of the hallway, is Yuzu's bedroom—marked by a big sticker of a pink teddy bear with a heart on its belly.
~Why does she get a cute teddy bear for her door and I get a giant penis...?~
«Thank you so much for helping me, you were really super sweet!»
Yuzu's room is all pink, with a soft bed, a few wardrobes, and a massive bookshelf that could rival a full library. This leaves Hakuto genuinely puzzled—judging by appearances is a mistake, but he never would've guessed she was an avid reader.
«Oh, it's nothing. We're siblings now, right? Helping each other is the least we can do.»
Hakuto is about to leave the room, but Yuzu stops him by grabbing his t-shirt.
«Aren't you curious to know what's in the box?»
«Um… no.»
«Ugh! Ask me what's in the box!»
«But I'm not interested!»
«Just do it! I won't let you leave until you ask!»
Hakuto lets out a resigned sigh.
«What's in the box...?» he asks in the most uninterested tone possible.
«Oh, I'm happy you asked!» Yuzu cheers.
~But she was the one who forced me to ask that…~
With a theatrical flourish, Yuzu opens the big box… revealing tons of bikinis and other beach accessories.
«Wow, swimsuits... Can I go now?»
«Of course not! You just said siblings help each other! It's the middle of summer, and I haven't bought any new ones yet—obviously, you're coming with me to get some. But first, we need to decide which of last year's swimsuits to keep and which to toss.»
«And you can't decide that on your own?»
«Of course not! A male opinion is essential in these situations! I have to impress the boys!»
~I think she could impress any boy on Earth even wearing rags...~
«I'll try them on one by one—you tell me what you think!»
Yuzu starts pulling her shirt off over her head. The small bumps of her nipples press through the tight fabric, just like when she greeted them earlier—a clear sign she's not wearing a bra now either. Instinctively, Hakuto turns away, giving her his back.
«Huh? Don't tell me you're embarrassed to see your little sister naked? We're family—these things should be natural between us.»
«Y-Yeah, you're my little sister, but… only for a few hours!»
«So what? I was really looking forward to showering with my big brother… all my friends do it, ugh...!»
~I don't think that's exactly normal...~
«...a-almost there… why won't it go in? …damn… oh, done! You can turn around now!»
When Hakuto turns to Yuzu, he nearly faints. The bottom part is fine—The light blue bikini bottom, though thin, fits her perfectly—but the top… looks like it could burst at any second! It's so small it barely covers her nipples, pressing her breasts like they're tied with a rope.
Only a tiny gold ring between her breasts, straining under pressure, holds together the two clearly undersized cups of the top.
And then, the inevitable happens...
—CRACK!
The ring snaps, and only thanks to superhuman reflexes does Hakuto manage to look away at the last second as Yuzu's top drops to her feet.
«Oops... I didn't think my boobs had grown so much since last summer. I guess I'll have to give them all to Rika—they'd definitely fit her. I'll borrow one from Mom for this afternoon's pool party to celebrate our families joining. It'll be too big for me, but better than nothing. I can't risk my shy big brother having a heart attack from seeing his little sister's boobs.»
«Yuzu, give me a break...!»
