3Some

After school, I decided to head home with Yumika.

“Where are we going today, Sakiya?” Yumika asked.

“Sorry, but we’re going straight home again today. Kana seems to have come back home this afternoon. She’s probably feeling lonely and sad, so I want to show her my face as soon as possible,” I replied.

“…You’re such a siscon,” Yumika said, giving me a look of exasperation.

I couldn’t deny it since I cared deeply about Yumika, my twin, as well.

“Sorry I can’t prioritize you today, Yumika.”

“It’s fine. It’s not good to be selfish, and Kana-chan deserves some Sakiya power too.” 

“Sakiya power? What’s that supposed to mean?”

“Seeing you gives me energy. You feel energized when you see me too, right?”

“Yeah, that’s true.”

Satisfied with my answer, Yumika clung to my arm. The surrounding students looked at us with envy.

“I’m home” 

“Onii-chan!!” Kana leaped at me the moment I stepped inside. Her ambush style was reminiscent of Yumika’s.

“It’s been a while. How have you been?”

“Not good at all! But I brought you a souvenir!” Kana exclaimed, hugging my waist.

I patted her head, and she beamed with joy. She really is adorable.

Perhaps it was because we hadn’t seen each other in a while, but I felt an intense desire to be closer to Kana. It was a strange feeling that made me want to regain my composure.

Could it be that Yumika’s presence is causing my sense of morality to glitch?

Regardless, I think my sense of appropriate boundaries has already gone haywire. I touch Kana just as freely as I do Yumika.

“Our life alone together is over,” Yumika said, clinging to my left arm.

She seemed to be competing with Kana, and soon, the two of them were vying for my attention.

“You’re getting too close to Onii-chan, Yumika-san.”

“We’re family, so it’s not a problem.” 

“Do you love Onii-chan?” 

“As family, I love him very much. Just like you do, Kana-chan.”

Yumika smoothly evaded Kana’s direct attack.

Kana clearly sensed Yumika’s deeper affection for me.

“We’ve only been living together for a few months. You don’t really know Onii-chan that well.” (Kana)

“We’re already on the same wavelength. Don’t underestimate the bond of twins.” 

“I have more memories with him.” (Kana)

I separated the two as they bickered.

I wondered when they would ever get along…

Since our mother wouldn’t be back until tomorrow, the three of us had to spend the day together. I hoped no issues would arise, but that seemed like an impossible wish.

“Here, this is for you,” Kana said, handing me the souvenir after dinner. It was yatsuhashi, and since I love sweets, I was genuinely happy.

(Yatsuhashi is a japanese confection, mainly a souvenir snack, made of glutinous rice flour, sugar, and cinnamon)

“Yumika-san, this is for you too,” Kana added, passing another package to Yumika.

“Thank you,” Yumika replied, taking the pink-packaged strawberry-flavored yatsuhashi. Kana had thoughtfully gotten a girly flavor for her. My sister is really considerate.

“I’m a bit sleep-deprived and tired, so can you sit on the sofa, Onii-chan? I want to use you as a pillow.” 

“Go sleep in your room. Don’t use me as a pillow.”

“Is that… no good?”

“…It’s fine, I guess,” I relented, unable to refuse Kana’s request. As I sat on the sofa, Kana clung to me and started to doze off.

“You’re such a doting brother,” Yumika commented, looking at me with a hint of disdain.

“Ever since you started coming over, Kana’s been acting extra clingy.” 

“I can understand her feelings. If I were in her position, I’d do the same.” 

“Why?”

“Because I wouldn’t want to lose you. It’s similar to how children get jealous when a new sibling is born and feel neglected.”

“I see,” I said, realizing that having Yumika around might be making Kana feel insecure about her place in my life.

“That doesn’t mean I’m willing to give up my time with you, though.”

“Be nicer to Kana, will you?”

“Sympathy has no place in this battle. This is a woman’s war.”

Even though her opponent was Kana, she had no intention of yielding. No wonder they couldn’t get along.

“Mm… gotta use the bathroom,” Kana mumbled, waking up and staggering off to the bathroom in a sleepy haze.

“It’s my turn now,” Yumika announced.

As soon as Kana disappeared into the bathroom, she latched onto me in the same way.

“Which one of us is more comfortable to hug?”

“Both have their own unique charm.”

“You’re indecisive,” Yumika said, pressing her chest against me, as if to prove a point.

“Hey, that’s my spot!” Kana exclaimed, returning from the bathroom and finding Yumika in her place.

“Sakiya belongs to everyone. Your objection is noted but not accepted.” Y

“Hmph,” Kana grumbled, unable to come up with a counterargument. She clung to me from the opposite side instead.

This was a problem…

Yumika’s presence was making Kana more assertive, and Kana’s assertiveness was making Yumika more assertive.

What a vicious cycle.

While it felt good right now, I had a bad feeling about where this was headed.

A dangerous thought crossed my mind—what if this escalated to a threesome?

No, no, what am I even thinking?

When did I start having such perverted thoughts?

Yumika is my twin, and Kana is my sister.

I shook my head to clear away the inappropriate fantasies of being sandwiched between a naked Yumika and Kana.

This was getting out of hand. My mind was a mess.

Sadly, it seemed like I could no longer return to being a normal person.
