【INS-mode】My Ideal Sister 4

This is the fourth installment of my original brother-sister series.
You can read [Ideal Sister] 1 (unabridged) and the rest can be read from anywhere.
This is a continuation of the general story.

This is the story of my ideal sister, Yume, who is cheerful and brotherly.
In my dream, however, I’m having sex with the douchebag Yume.
It’s a dream, right? It’s a dream, isn’t it?
