Not my Sister (Y/N × G!p Aki)

Chapter 27: Private Lessons

"Aki-nee...."

Aki didn't waste time and she jumped on Y/N's lap. The girls engaged in a lip-lock and spent the night doing sexual activities

"Hah?! When did I get scores these low?"

Y/N was wide eyed when she received the results of her test. She was sure that she understood most of the lessons but because of her exhaustion due to last night's activities, she dozed off while taking the test.

And alas, Y/N got a low score which meant that she has to take the removal test at the end of the week

"Ooh, at least you didn't get a 0." said Rui as he patted Y/N's shoulder.

"Ugh. I studied for these and know most of the items." Y/N whined as she examined her testpapers. "If I wasn't so tired from last night... "

She sighed and shifted her attention to Rui.

"What about you, Rui? How did you do?"

"Same old same old." shrugged Rui as Y/N scanned his testpapers. The boy managed to get a passing score for all subjects.

"This sucks. I should really focus next time." Y/N yawned and Rui blinked curiously.

"What made you up all night, anyways?"

Y/N gave off an awkward laugh in reply.

"It's nothing."

"I've decided. I will not have sex with you again until the test results are getting better!"

Y/N flinched upon hearing Aki's booming voice. When she showed the test results,  Aki was disappointed and Y/N didn't expect that the girl will get so worked up

It was partly her fault why the test results ended up like that.. though." mumbled Y/N as she met Aki's frown

"What? Do you have any problems?"

"Wah- Nothing." Y/N looked down on the floor

"And Y/N, you're not allowed to masturbate either, got it? Stop thinking perverted thoughts and focus on studying!"

After the sermon, Aki prepared some questionnaires for Y/N. She would check the answers from time to time and she also made an effort to avoid Y/N as much as possible

The days went by with Y/N focusing on her studies and limiting her interaction with Aki.

"This is exhausting. Does Aki-nee have to increase my workload?" Y/N's head fell back on the table tiredly. She was studying in the living room and finished half of the worksheets given by Aki

" To begin with, I understood most of the lessons. I was just tired after she and I...."

Y/N's thoughts drifted off to sexual ones and she shook her head at this. She lightly slapped her cheeks to rid of the thoughts.

"Argh! Why do lewd thoughts disturb me?"

Y/N glanced to the side and saw Aki who just finished taking a bath. Their gazes met and Y/N's eyes slightly widened at Aki's nude form

".................."

"Ah..."

"Aki-nee -

"CONCENTRATE ON YOUR STUDIES!"

"H-HAI!"

Y/N went back to her room. She flopped to the bed and groaned tiredly.

"Even if Aki-nee says that.. I can't concentrate when she is around!"
