Chapter 53: A Sunscreen Struggle and a Watery Wonder

“Ugh…”

Luo Xi’s heart skipped, staring at the blushing, shy beauty—wait, that’s my brother! She whipped her head to the window, ears red.

“D-done…?”

Luo Su hung her head, tail twitching nervously. Wearing a full girly outfit in front of her sister… no words needed for how embarrassing!

“No way!”

Luo Xi snapped back, taking a deep breath, grabbing bottles from her suitcase. “Here, come—sunscreen time!”

“I-I don’t need it…”

Luo Su retreated guiltily, recalling a guy mocked for sunscreen during training… No way she’d do it!

“Hurry, or I tug your tail!”

“…”

At Luo Xi’s words,

The little succubus pouted, shuffling over, tail trembling with grievance.

“It’s not hurting you!”

Luo Xi sighed, but couldn’t resist lightly pinching the tempting, swaying tail.

“W-wah!”

Luo Su’s legs buckled, nearly collapsing. “Ugh… I came already!” She clutched her tail pitifully—her sister had no mercy!

“…”

Luo Xi felt guilty, forgetting the heart on the tail needed… gentle pinches.

…

Luo Su sat on the bed.

From 9 a.m. to nearly 10:30—early outing? Girls’ prep was scary. Her tail swayed boredly.

Finally, Luo Xi spoke.

“Let’s go!”

With a sneaky thought, she tiptoed. Hehe… still two centimeters taller!

“…”

Luo Su noticed, tail dragging glumly. Height… nothing she could do!

But… she’d probably, maybe, grow taller.

Gulp… not sure.

In the taxi, Luo Su gingerly stepped in her new shoes—first time with slight heels. If she didn’t run…

She could balance.

“First stop, aquarium!”

Luo Xi waved her phone guide, excited. Luo Su nodded, thinking girls can’t resist romantic spots.

“Hmph… not me!”

Puffing her chest proudly, unaware her tail swayed to her sister’s phone rhythm—left, right.

“Ugh… say,”

“What special fish will the aquarium have?” Luo Xi scrolled video guides, asking eagerly.

Luo Su blinked.

Now her sister seemed like a sister. Teasingly, “Braised fish… pickled fish, grilled fish…”

Before finishing—

Thwack!

Her head took a hit. “Deserved!” Luo Xi huffed. “Who goes to an aquarium thinking of eating…”

“Ugh…”

Luo Su clutched the bump, teary. “I-I was joking! Why so hard…”

“Hahaha…”

The driver laughed. These cute girls were fun. “Aquarium’s not just fish—dolphins too~”

“Mhm!” Luo Xi nodded.

Luo Su muttered, “Hmph… still fish.” Never been, but online videos weren’t impressive—she doubted it’d be fun.

…

“Here!”

At the driver’s call, Luo Xi gripped Luo Su’s hand, stepping out. “Ugh… why hold hands?” Luo Su blinked.

“Scared my cute sister’ll get lost!”

Luo Xi was firm. “Aquarium’s crowded.” Luo Su’s face reddened. “I’m not a kid!”

“Go!”

Holding the succubus’s hand, kid or not, she just wanted to.

“S-slow down!”

Luo Su blushed, fumbling to calm her tail:

This dumb tail… happier than me!

Am I… secretly a hypocrite? Gulp… She shook her head. No way!

“Ugh…”

“Definitely not!”

Shaking harder, banishing the thought, they passed the ticket gate, fluorescent stamps slapping down, stepping into a blue water world.

“Wow…”

Instantly!

Luo Su’s hand trembled—behind the glass wall, fish swirled like a galaxy. (So beautiful…) She pressed close, breath fogging the glass.

…

Her tiny nose nearly touched the glass, eyes wide, tracking the fish in awe.

“Ugh…”

Luo Xi covered her mouth. Her brother… too cute! Sneaking a photo, she bubbled with glee.

“Let’s go!”

Rubbing his head, she smirked. “More fun fish inside!”

“Cool!”

Luo Su nodded excitedly. Some places you had to see in person—videos didn’t compare!

Blue light danced on her face,

Like being in the deep sea.

“Ugh…” Snapping back, she clutched her back, whining, “Why tug my tail again!”

“It’s slipping out!”

Luo Xi pinched her soft cheek. “Dumb brother, can’t even control your tail?”

“Ugh… no way!”

Luo Su turned guiltily, hands fumbling under her skirt. Luo Xi sighed, handing over a hair tie. “Use this.”

“Mhm!”

Luo Su nodded, mischievously wrapping it around her tail extra times. “Take that, disobedient tail!”

“…”

Luo Xi blinked. Fighting her own body? Too cute! Hmph… her brother must’ve grown up on cute!

“Let’s see dolphins!”

“Yeah!”

…

Time ticked by. Luo Su, face flushed, leaned on the glass, panting. “Can we… rest?”

Still fun,

But… ugh, exhausting! Especially in this dress.

“Fine!”

Luo Xi led him to a corner to sit, waving her phone smugly. “So cute!”

“What?”

Luo Su leaned over eagerly. “Wah!” Her face steamed red. “D-delete those!”

Her phone…

Full of her cute pics! If these leaked… her reputation was toast!

“No way!”

Luo Xi dodged gleefully. Shy brother? Cutest! Delete? Never.
