(Oh... what on earth am I doing? This is so... scandalous!)
Viola Rosemary writhed inwardly as she pressed her body against Rest while tutoring him.
If it were socially acceptable, she felt like rolling around on the floor in sheer embarrassment.
Though she seemed composed as she pressed her chest against him, Viola was anything but calm.
She was merely suppressing her shame through sheer force of will, driven by a fierce sense of rivalry toward her twin sister, Primula.
(Ugh... why is Primula so unfazed? She’s clinging to a boy our age while wearing such a suggestive outfit...!)
Viola was wearing a yellow nightgown.
It was just her usual loungewear, not inherently "lewd" in and of itself.
However, the fabric was thin, and it clearly showed off the cleavage she’d only recently started to develop.
While it might have been fine around family or other girls, it was certainly not the sort of thing a boy her age should ever see.
(I didn't actually intend to wear this, but it’s all Primula’s fault for putting hers on first...)
Viola had intended to start tutoring Rest today in a casual everyday dress, not a nightgown.
But then her younger sister, Primula, had appeared in a light blue nightgown.
While Viola turned red at her sister’s sheer audacity, Primula had shot her a triumphant smile.
Consumed by a spirit of competition, Viola had immediately changed into her own version of the same nightgown, purchased in a different color.
"Rest-sama, this problem is much easier to understand if you refer to this book, you see?"
"Um... like this?"
"Excellent! That's wonderful!"
When Rest solved the problem, Primula hugged him while showering him with praise.
Viola’s competitive streak flared instantly, and she pressed her body against his other side.
"That's amazing, Rest! Keep it up!"
(I-In the first place... Primula is being totally unfair! She’s usually so quiet and always hiding behind me... so why is she being so aggressive with Rest?!)
To Viola, Primula was her precious little sister.
The apple of her eye... her soul’s other half, for whom she would trade her very life. She was as vital to Viola as her own heart.
Primula was supposed to be the one she protected, yet now she stood as a formidable rival for a single man’s affections.
(H-Has she grown up without me realizing it? Or is it because Rest is special? Even her chest has developed that much... at this rate, she'll steal Rest away!)
The Rosemary sisters were identical in almost every way except for their hair, eyes, and personalities—but for some reason, Primula’s chest was slightly larger.
Viola had never cared about the difference before, but now it was starting to get under her skin.
Feeling outmatched in her feminine arsenal only served to fuel her growing agitation.
"Oh, in that case, Sister! How about we give him a 'Punishment' instead of a reward?"
When Rest made a careless mistake on a simple problem, Primula offered the suggestion.
(P-Punishment? Wait... Primula, what are you saying?! What?!)
"That’s a great idea! Primula, you’ve said something wonderful!"
Despite the internal panic, Viola spoke the exact opposite.
Seeing Primula’s eyes grow moist with a sensuality that belied her fifteen years, Viola found herself unable to back down.
"Well then, time for your Punishment. Here I go...!"
"Rest-sama, please prepare yourself...!"
(Wait... I'm really doing this to a man who isn't even my husband or lover... Hyaaaaaaaaaaaah?!)
Following her twin sister's lead, Viola reached out and carried out the Punishment on Rest.
In truth, Viola was panicking so completely that her head spun as if she might collapse at any moment; nevertheless, she still let her fingers crawl over the body of the man she loved.
