Prologue

“U-Um… could you turn around? I’m about to change…”

Serina Ruka said shyly, clutching the bedsheet to cover her body.

Even concealed by the sheet, her delicate frame—so fragile it seemed it might snap—exuded an indescribable sensuality.

“Y-Yeah, got it,”

Minato replied, flustered, turning his back to Serina.

On the very first day Serina spoke to Minato face-to-face, she had boldly lifted her skirt to reveal the athletic shorts underneath.

Since then, Serina had continued to act in ways that made it hard to believe she was just a “friend” he’d only recently met, with gestures bold beyond measure.

Though, to be fair, each time left Minato reaping quite a few… perks.

This was Minato Toshiya’s own room.

The space wasn’t particularly spacious, and the laptop Serina had been using earlier hummed softly with the sound of its fan.

But right now, the most pressing matter was—

“Ugh, for some reason, I just can’t get this bra on…”

“Want me to help you with it?”

“Oh, yes, please… thank you…”

Is this really okay? Minato nearly blurted out the quip.

It seemed he no longer needed to keep his back turned, so he faced Serina again.

Serina was sitting on the bed, her back to him.

Minato climbed onto the bed, positioning himself behind her.

“…”

He couldn’t help but swallow hard, the sound echoing in his throat.

The white bra was already draped over her shoulders; all that remained was to fasten the clasp.

Her bare back, uncovered by the bra, was smooth and pale, its mere sight stirring a provocative allure.

How could such a pure, innocent girl radiate such overwhelming sensual charm?

“Hm? That’s odd…”

“Sorry, Serina. Instead of helping you put it on, I kinda want to take it off.”

“Eh…?”

Serina turned her head in surprise.

The unfastened bra was slipping, revealing nearly the entirety of her modestly sized yet perfectly proportioned breasts.

“W-Wait? Didn’t we already do it so many times just now… a-another round?”

“Yeah… it’d be such a shame to cover up such beautiful breasts with a bra.”

“I-I always wear one, you know. I mean, I’m the type who wears a bra…”

Lately, Serina hadn’t been wearing shorts or safety pants—not even athletic ones.

Though her uniform skirt reached almost to her knees, it still felt… dangerously short.

“No good? I want to take it off… and do it with you again, Serina.”

“A-Another time…?”

Serina murmured shyly before lying back on the bed.

The bra had almost completely slipped off, exposing not just the full curve of her breasts but even the delicate pink tips.

“I-It’s okay… we’re friends, after all.”

Though her face was flushed crimson, Serina managed a smile.

Not only was she an incomparably pure beauty, but she was also a female friend who, if asked, would always agree to let him have his way with her—
