You’re going to stay at your sister’s house, and she’s a good friend of yours.
But she loves you so much…

I’ll make you your favorite meal.
I’ll even scratch your ears.

Of course, I will wash your body in the bath.

[Hey? Why?
Why is your penis getting so big?

[You won’t understand if I don’t say anything, will you?
Sis, I’m just washing your penis.
Why are you getting bigger?] [

This is how our private [night study time] begins.
