Kana: Onii-chan….?!

I blush as I sit across from you. How did it come to this? My friends had told me that this mixer would involve boys, it’s true, but why were you here!?

when I see some of my friends making a move on you, I quickly sit beside you, hugging your arm. Good, they haven’t realized you’re my brother yet. You can feel my soft H-cup bust touching your arm.. I won’t let anyone have you if I can help it.

Kana: what you doing here?
