After lunch, they decided to head to the mall—not just Haruka and Haruto, but also Chiyo. Initially, Haruka wasn't thrilled with the idea of Chiyo tagging along, but since all three of them would be going to the resort, she needed a good swimsuit too.
Now, Haruto found himself standing in front of the changing rooms, waiting as both women tried on swimsuits and some one-piece dresses.
The shop was packed, as expected during the summer vacation rush, filled mostly with women, and like him, a few men stood around, clearly in the same position of dutifully accompanying their girlfriends.
He leaned against a wall, idly tapping his foot, while the retail staff hovered behind him, glancing his way more often than necessary.
Each time he turned to meet her gaze, she would quickly avert her eyes, pretending to be busy.
He raised an eyebrow, curious but unconcerned, and glanced at his reflection in the nearby mirror.
He was dressed simply—army-colored shorts, a white T-shirt, and sneakers, with a sling bag strapped across his back. Totally normal.
The only noticeable difference was his hair. Haruka had insisted on styling it into a half-ponytail, and he'd reluctantly agreed.
"Err... sir, would you like to try some of our men's swimwear as well?" the staff member suddenly asked, her voice tentative.
Haruto considered her suggestion for a moment, but before he could respond, the changing room curtain was flung open, and Haruka stepped out.
"How is it, brother? Does it look good?" she asked, twirling around in a soft pink bikini that shimmered under the store lights.
The bikini was delicate, with a triangle top held together by thin halter straps.
Golden chains draped from the neckline, adorned with tiny seashell and crystal charms that caught the light and twinkled with each movement.
At her hips, a matching wrap skirt tied effortlessly on one side, the fabric flowing around her like a gentle breeze.
Haruto's eyes widened in surprise, a smile tugging at his lips. "Of course, it's good. You look great in everything."
Haruka pouted, placing her hands on her hips. "Really? You say that about every swimsuit I try on!"
Haruto paused, scratching the back of his neck. He wasn't lying—his sister really did look radiant in everything she tried on.
But as he scanned the room, he noticed other men sneaking glances at her, and a protective surge rose within him.
'Damn it, look at your own girlfriend!' he grumbled inwardly, casting sharp glares at anyone whose gaze lingered too long on Haruka.
"Brother! Which one is better?"
Haruka snapped, crossing her arms in frustration as she caught him glaring at strangers instead of focusing on her.
Haruto shook his head, snapping out of his thoughts. "This one's the best," he said, offering her a warm smile. "Pink and red really suit you."
Haruka studied her reflection in the mirror, rubbing her chin thoughtfully. "Hmm... just in case, I'll try on a few more!"
She turned on her heel and disappeared back into the changing room, leaving Haruto to sigh in resignation.
As Haruka emerged from the fitting room again, fully dressed, she grabbed the shop staff by the arm.
"I'm going to pick out more! You stay here, brother, don't go wandering off," she called over her shoulder, leaving him alone once more.
Haruto shook his head, smiling softly. At least his sister was happy, alive, and full of energy. That was all that mattered.
He shifted his attention to the left changing room, the one that hadn't opened for over fifteen minutes.
A smirk tugged at his lips as suspicion crept in. Silently, he approached, his sneakers making no sound on the tiled floor.
When he reached the white curtain, he casually pulled it open, revealing Chiyo inside.
Her startled scream barely escaped before he covered her mouth, muffling the sound. "Shh… What have you been doing here for so long, Mother? Masturbating or something?" he teased, grinning.
Chiyo's face flushed a deep red, her hands instinctively moving to cover her exposed body. She wore a skimpy black string bikini that barely concealed anything.
The thin material covered only her nipples and the bare minimum between her legs, the rest of the swimsuit held together by delicate strings that wrapped around her neck and hips.
Her long, toned legs and thick thighs added to her sensual appearance, especially the way her rear was left almost entirely uncovered.
Haruto's eyes lingered on her round breasts, noticing how her nipples had hardened beneath the fabric.
"Are you really getting horny right now?" he whispered into her ear before nibbling at it, making her shiver.
['Whispering Allure' skill automatically activated!]

[ERS would decrease by 5 every minute.]
"Ngghh~ Haruto, please not here," she whispered, her fingers pressing against his chest in a weak attempt to push him away.
"Really? But your body's telling me, 'I want to be fucked right here,'" he growled, his voice low and teasing as he leaned in closer.
Chiyo's soft whimper was the only response as her legs trembled, her body betraying her.
He slid his knee between her legs, pressing it against her crotch.
Chiyo gasped, a moan slipping out as she protested, "Ahhh! Haruto, the swimsuit will get dirty!"
"It's fine," he murmured, his breath hot against her skin. "I love this one. Let's just keep it."
Her resistance melted away as she relaxed in his arms, her body responding to his touch. Haruto's attention shifted briefly as he heard the familiar chime of the system in his mind:
[Chiyo's libido increased by 20%!]
[Libido Percentage: 80%.]

A low chuckle escaped him. The quest was perfect, adding an extra thrill to the situation. The adrenaline of getting caught made it all the more exciting.
