Well remilia did imprison flan for nearly 500 years. So many life times trapped in a room would make even the sane go crazy. So um ya, way to go reminder, you broke your sister and make her awaken to some one habit.
Remilia-san...To be honest, when onee-sama punished me... I was scared and in pain, you know?But she only did that out of concern for me, so, basically...Remilia-san!!Kogasaaaaaa?ba-dump
da-dump
and put this thingy here on me for today, okaaaay......being punished means you're loved!And that's why, Kogasa! If you could do this little favor for me...My little sister's fetish...!!
I'm sorry...
I wanna die...
....before doing whatever you want with me without any care for consent, forcefully...
