Grrr.
The Hachimi engine rumbled against her thighs.
The moment Yukina sat down on the sofa, Huahua immediately jumped up.
Its soft paw pads pressed against her thighs again and again as it tilted its head up, acting spoiled and begging to be petted.
“What a spoiled little meow.”
Yukina complained softly, yet her hand had already reached out.
She stroked from the back of Huahua’s head all the way to the base of its tail. The Hachimi engine grew even louder.
Ding ding dang dang.
From the kitchen came the soft clinking of porcelain.
A certain pink-haired succubus older sister walked out from inside.
She was wearing a completely useless white apron.
Both hands held a plate. Her tail was curled around a fork as she approached step by step.
“Here it comes, here it comes~ Little Yukina’s favorite strawberry cream cake is here. Aren’t you looking forward to it?”
Porcelain gave a soft sound.
The plate was set on the table.
A gem-like glittering cake appeared before her eyes.
The shape had been cut very neatly.
The surface of the cream was smooth and fine.
After Onee-chan used her tail to set down the fork, the tip of the tail casually straightened the strawberry on top.
The half-cut strawberry swayed slightly. Pink juice seeped out and soaked into the white cream, carrying a faint watery sheen.
“…Thank you, Onee-chan.”
Yukina lowered her head and stared at that strawberry for two seconds.
This was the strawberry cream cake that the original owner of the body liked the most. It was not hers.
It was not that Yukina disliked it.
She simply was not particularly interested.
In her previous life she had rarely had the chance to come into contact with foods like cake, so she could not really talk about liking or disliking it.
Moreover, the cake right in front of her was a gift from Onee-chan Yuna to her little sister.
Yet it was going to be put into the mouth of an “outsider” like herself.
A faint, indescribable sense of guilt always rose in her heart.
“What’s wrong? Don’t you want to eat the cake?”
Yuna noticed that her little sister still had not moved.
She smiled foxily and hooked her fingers around the shoulder straps of the apron, tugging them slightly downward.
“Or~ do you want to eat Onee-chan first before eating the cake~?”
“…I’ll just eat the cake.”
“Aiyah, what a pity.”
Under Onee-chan’s smiling gaze, Yukina picked up the fork, dug out a piece of cake, and placed it into her mouth before the soft sponge could spring back, then closed her lips.
…Sweet.
So sweet.
The thick sweetness of cream mixed with juice spread across the tip of her tongue.
Yukina’s eyes brightened for a moment.
Was it because she had not eaten anything since noon yesterday?
The sugar rapidly spread through her body via her taste buds.
Her cells absorbed the energy as greedily as a dehydrated sponge.
Under normal circumstances, Yukina might have found it too sweet—sweet to the point of being cloying.
But for her current self, it was just right.
She took another bite.
This time she bit into the strawberry.
The slightly sour juice mixed with the sweetness of the cream melted in her mouth. Her previously hazy brain seemed to clear up a little.
“How is it? Delicious, right~?”
Seeing her little sister’s surprised expression, Onee-chan Yuna smiled happily and sat down beside her.
“It’s delicious.”
Yukina blinked and raised a hand to lightly cover her chewing lips.
Her voice came out a little muffled.
“Then, shouldn’t Onee-chan receive a reward~?”
“…A reward?”
Before Yukina could even understand the meaning of those words, Onee-chan had already picked up Huahua from her thighs and placed it on the other side of the sofa.
Then she herself burrowed into her little sister’s embrace, rested her head on her thighs, and rubbed against them again and again.
An adult nearly 180 centimeters tall curled up into a ball.
Her tail swayed back and forth through the air.
“Ahh~ Even the highest-grade pillows in the world can’t compare to a little sister’s thighs. This elasticity, this texture— subarashii~”
“Onee-chan is so sticky…”
Yukina held the fork in her mouth and complained softly.
She could not even be bothered to count how many times she had been harassed by this older sister since earlier.
It felt as if their bodies had barely separated at all.
Meow. Huahua also complained, yet it was being toyed with by Onee-chan’s flexible succubus tail as if it were a cat teaser, jumping back and forth.
“It’s only natural for an older sister to act spoiled toward her little sister. Besides, Onee-chan has already worked hard for a whole day. Hurry up and praise me.”
Pink, slightly wavy hair burrowed back and forth in Yukina’s arms.
What a willful adult.
Yukina muttered softly in her heart.
However, she was also very clear that Onee-chan’s work was truly exhausting.
She was usually so busy that she did not even have time to come home and eat.
She often had to work overtime until dawn, surviving on coffee and energy drinks.
There was no helping it. As the “proxy” little sister, she should properly comfort this corporate slave of an older sister.
She set down the fork in her hand, leaned forward a little, and spoke softly beside Onee-chan’s ear.
“Alright, alright. Onee-chan is amazing. Today’s Onee-chan worked very hard.”
“Ohohohohoho~♡”
“D-Don’t suddenly make such a scary sound.”
She had not expected Onee-chan’s reaction to be this big.
Yukina was startled.
“Oh. It’s fine, it’s fine. It’s just that being whispered to by such a cute little sister made me go a little bit.”
“Onee-chan always says things people can’t understand.”
“Don’t mind it. Praise me a few more times.”
“Mm… Onee-chan is the best. Onee-chan, do your best.”
“Oho~♡”
“Again…”
“It’s too wonderful. This world is too wonderful. Right now, even if I work overtime to death, I will have no more regrets.”
“You can’t die. You have to live properly.”
“—Ah, I understand, Mom.”
“It’s little sister, not Mom.”
“Can’t a little sister become a mom?!”
Onee-chan Yuna flipped over and lay face-up on Yukina’s legs.
Her eyes sparkled. She held her breath and spoke with righteous conviction.
“Does the law stipulate that a little sister cannot become a mom? It doesn’t, right? How could a little sister be such an inconvenient existence.”
“…Of course there is. What exactly do you take a little sister for.”
“I don’t care. I’m going to create a world where a little sister can become a mom. Anyone who objects will be executed!”
“Is Onee-chan some kind of evil final boss?”
Yukina felt a little too powerless to even complain.
This idiot older sister really liked her little sister far too much.
Far too much.
Liked her to the point that…
Yukina did not dare imagine what kind of reaction she would have when she learned that the “little sister” she liked so much was actually no longer here.
…
The Yukina named “Small Fry F” was killed in most of the game’s story routes.
Either she was killed by a berserk Mashiro, or she was killed by a fallen male protagonist, or she might simply be disposed of as collateral when Yumiko was abandoned by the antagonistic organization.
In other words, in those timelines, the older sister currently lying on her thighs and acting spoiled could only stay alone at home, prepare the cake, and wait for a little sister who would never return.
…The original owner of this body really was an idiot.
Why did she have to join Yumiko’s bullying group just for that meaningless bit of class status and bring a fatal disaster upon herself.
But the current her, who had stirred the game’s plot into complete chaos and covered this body in wounds from head to toe, also seemed to have no right to say such things.
We’re both failing little sisters, aren’t we.
The remaining half of the cake on the plate had already begun to melt.
The surface of the cream slowly collapsed.
The strawberry embedded on top rolled into the porcelain plate, leaving a streak of light red.
Silence lasted for ten seconds.
“Yukina.”
Onee-chan suddenly spoke.
Yukina slightly returned to her senses and looked down at Onee-chan.
“Onee-chan, what’s wrong?”
She suddenly noticed that Onee-chan’s gaze was a little strange.
It was different from her previous laughing and joking state.
She seemed to be hesitating over something, and also a little nervous.
“Onee-chan has said before that I wouldn’t ask about the things that happen to you at school. But you know, as a guardian, Onee-chan still has to be a bit long-winded, so…”
Onee-chan Yuna went around in a large circle before finally asking the question that had been in her heart.
“Have you… been bullied at school?”
