“I’VE BEEN SET UP AGAIN!”

While still in the bath, I called Shiho just like before.

The phone rang twice and connected.

“Hello, Hello Sei-chan.”

“You set me up again Shiho!”

“Ah-Ahahahaha, well it shouldn’t be too bad since Sei-chan told me yourself, right?”

“I see, I see. That means Shiho doesn’t need to learn to cook from me, right?

“I’m sorry, Sei-chan, it was all my fault.”

Shiho immediately apologized.

If Sei-chan, an experienced cook, was struggling to teach her, how could she stand a chance to learn how to cook herself?

It would take her years to get good enough to feed people if she ever did it alone.

“Speaking of which, Sei-chan, your voice sounds strange over the phone, where are you calling from?”

“A bath. I’m taking a longer soak because I’ve been working out hard today.”

“Ah yeah, wanna video call?”

“I don’t mind, but what’s the point of doing so?”

“Nothing, I just feel like it.”

There was no particular reason to refuse, so I agreed to Shiho’s suggestion and switched to the video call option.

Whilst soaking in the bath, I held my phone vertically so that it reflected the area around my face.

“Is this good?”

“Un! Sei-chan! It’s been a while.”

“We met at school today so it’s only been a few hours.”

“Ahaha, right… Ku-”

“W-What’s wrong?”

Shiho looked pained on the screen, so I asked curiously.

“No… I switched to a video call for this, but… it still hurts just as much.”

“What do you mean?”

“I’M TALKING ABOUT THE TWO MOUNTAINS FLOATING IN THE WATER! SEI-CHAN!”

“Whaa? Y-You did it just for that!?”

I got so embarrassed that I immediately covered my chest using the arm that’s not holding the phone.

“No… It’s just that… I heard that Shigemoto likes big breasts.”

“A-Ahh, Tojoin-san did say something like that, yeah.”

Last week at the amusement park, when Shiho and Tojoin were confessing their feelings to Shigemoto, they had quite a debacle.

And Tojoin-san definitely said that, whilst Shigemoto on the other hand, didn’t deny it one bit.

It was quite a terrible revelation to be revealed so openly, and I felt a little sorry for Shigemoto at the time.

“And so, I wanted to make my breasts bigger, so I thought I’d ask Sei-chan on how to do that.”

Shiho said as she brought her face closer to the phone with an intensity I could feel on my face.

“Tojoin-san is pretty big. But Sei-chan’s is bigger.”

“N-No, I’m not so sure about that. I didn’t compare with her.”

“Don’t worry! I used my own measurements! Sei-chan is definitely bigger.”

“Why are you so confident about that?”

“After years of gazing and envying people’s breasts, I HAVE ASCENDED…”

“Y-Yeah, I see…”

Shiho had a faraway look in her eyes, so I decided not to dig deeper into the topic.

“Plus, you got bigger compared to about 6 months ago, right?”

“H-How did you know?”

“It’s all thanks to the eye I’ve cultivated with over the years. I’m not too pleased with myself though.”

Over time, she even seemed to have even been able to see the growth of Sei-chan’s breasts naturally.

“I’d like to ask the trick to get bigger breasts, please.”

“T-The trick to making them bigger.”

“Yes! I even held down my shame and asked Tojoin-san about it, and she said ‘Ever since I was little, I’ve been massaging my breasts while fantasizing about Yuuichi rubbing them. It’s because of this that I’ve grown so much and had the kind of body that Yuuichi likes.’”

“What kind of an embarrassing conversation are we having right now…?”

Well, I do find it impressive that she has been making a conscious effort to do that ever since she was a child.

“So I’ve been massaging them while fantasizing about Shigemoto rubbing them since last week.”

“You don’t have to tell me that if you’re embarrassed, Shiho.”

“I-It’s fine! T-That’s why, I need you to teach me how to get bigger, much bigger than Tojoin-san herself!”

“Well, Shiho… I’m sorry to say, but…”

“Don’t worry, Sei-chan, no matter how hard it may be, I’ll do it!”

Shiho is determined to grow her breasts to be as big as Tojoin-san, and since she’s my best friend, I do want to share some useful information with her.

But…

“I never specifically set out to grow my breasts. They just grew… naturally.”

“Eh…?”

Shiho’s voice suddenly lowered to an expressionless tone.

“My mother’s was big too, so I guess, it’s, you know, genetic.”

“You didn’t do anything? Even when Tojoin-san needed to do it? You did nothing at all…?”

“Yeah, I don’t think I’ve done anything to make my breasts bigger, you know.”

“……”

“Shi-Shiho? C-Can you hear me?”

I called out to Shiho over the phone, which seemed to have stopped working, and whilst I was thinking that the phone was off,

Tch…

“Eh? Shiho? Did you just click your tongue?”

“Hmm? What’s wrong Sei-chan?”

“No, you just clicked your tongue, right…”

“Ahaha, I’m not the type to do that, Sei-chan.”

“Y-Yeah… I must have misheard you.”

Shiho’s face was smiling but her eyes weren’t so I decided not to pursue the matter further.

“So you didn’t do anything special with your breasts, Sei-chan?”

“A-Ah yeah… I’m sorry for being useless.”

“No, it’s fine, I’m sorry for suddenly calling you like this even though you’re in the middle of a bath.”

“No, I started the call so it’s fine.”

“See you tomorrow, Sei-chan.”

“Yeah, see you tomorrow.”

After that, I hung up the phone. I also felt a little afraid to meet Shiho tomorrow.
