Plain JK ch18: Accidental Onee-chan

p1
>Hey, Yui-senpai.

>I'm gonna be going out with my friends soon, but I'm not sure what clothes I should wear...
>I'm not all that good when it comes to fashion...
>Lemme see.
>I see~

>Hmm... This one piece dress looks like it'd suit you, Ayaka-chan!
>...! I see!
>Thank you so much, ONEE-CHAN!

>Ah.

p2
>...Just now, Ayaka-chan just called me "Onee-chan" instead of her actual sister Fumina.
>>Tanabata Fumina
>I messed up...
>This is what's known as "Accidental Onee-chan".

>In this case, it's not as bad as Accidental Mommy...
>Geez, I'm not your mommy, y'know?
>Nyaaah
>Accidentally calling your teacher Mommy... also known as Accidental Mommy!!
>but it still has the potential to be mentally scarring!! I have to make sure to respond to this is a proper and adult manner!!!

p3
>And my strategy for that is...
>Sorry, I got it mixed...
>Eh?

>Did you say something, Ayaka-chan?
>to pretend that I didn't hear anything!!!

>...Eh? Erm... I accidentally called you "Onee-chan", Fumina-senpai...
>She's stupidly honest!!!
>W-Well... I guess I didn't hear that...

p4
>That's okay then... Let's pick up where we left off...
>Ah, sure!

>I'm kindas worried... The latest fashion trends keep changing so quickly that I can't keep up at all...
>Even when I check social media, there's so many choices that I get confused.
>Yeah, yeah!
>It's not easy to get a grasp on all that!
>Alright! I managed to get through all that!

>At times like these... what would you do, ONEE-CHAN-SENPAI?
>...Ah.

p5
>Eh... No way. Again!?
>I did it again...
>What do I do!? How do I get out of this one!? Should I just become her onee-chan!? No, but...


>Geez~ I should just become your real onee-chan, Ayaka(star)

>You meanie... Pouring salt onto my wounds.
>I hate you.

>Hmm~... One wrong move and it'll end up like that! Since it's come to this...
>Hrm...

>...That's it!

p6
>I-It's okay, MAMA!
>...Oh, whoops~! I accidentally called you Mama!
>How embarrassing~
>DUAL MISTAKE! (Add to the mistakes) It's embarrassing... but this should help Ayaka-chan hide her shame!
>Hm? Mama...? But I'm younger than you?
>...Is this perhaps that "babumi" thing I've heard about?

>For someone who doesn't keep up with trends, her antenna sure picks up some strange tidbits!!!
>...!

>Fufu...
>Yui-chan, Ayaka-mama's here for you...
>!

p7
>Kh... I know I said it myself, but this is more teasing than I expected and it's so embarrassing...!!! In that case...
>...Geez
>D-Don't be so mean, Ayaka... Mama!
>!
>I'll fight fire with fire...!!!

>...I-It seems you've awoken to some strange fetish, so Mama will be going home now.

>...

p8
>...See you later,
>Yui-Onee-chan<3

>...Did she want to call me that... from the beginning?

p9
>Would you like some tea, Ayaka-chan?
>It's pretty hot, though.
>Ah, I would!

>Thank you, Onee-chan-senpai!
>...?
