17 Our first morning after~ (1/2)

The next morning, I woke up to see my cute little sister looking at me. We're both lying on the same bed, facing each other.

”Good morning, Nii-sama.”

”Good morning, Mio.”, I replied to her greeting as usual.

”How long have you been awake for, Mio?”

”Mm~~~ Around 3 hours 28 minutes and 43 seconds?”

”Who can count that accurately?!?!”, I retorted.

”So what have you been doing all this time, Mio? Surely, you can't just lie on the bed while being wide awake for 3 hours straight, right?”

”You can't?”, she tilted her head to the side in a cute way.

”Wait a second... YOU ACTUALLY LAID HERE FOR 3 HOURS STRAIGHT?!?!”

”Un!”

My sister is giving me a headache...

”So what have you been doing all this time, Mio?”

”N-Nothing...”, Mio flustered.

Since it seemed like my little sister wouldn't answer me no matter what happened, I decided not to push it any further. Thus, I just told my little sister to start getting ready to go to school.

”Nii-sama, let's take a bath together!”

”No.”, I replied immediately.

”B-But why?”, she started to pout.

That expression of hers... So unfair!!!

”M-Mio... We're already quite mature, yes? That's why we can't take a bath together...”

”Please?”, my sister started to beg like a cute little puppy.

”...S-Sorry, Mio. You can't.”

”Tsk, I thought that would surely work.”, my sister's expression changed in the blink of an eye.

”Hey?!?! What was that?!?!”

”Teehee ☆”, she playfully stuck out her tongue.

Jeez... This sister of mine can be quite troublesome, huh?
