SMA-661 - Hypnotizing my tsundere little sister into being my personal toy - Nana Usami

My tsundere little sister who usually just acts cold has become my personal toy after a single hypnotic session! Seeing her turn submissive and saying 'I love you, big brother' is just too much. I started unbuttoning her uniform and fondling her chest, and she was already leaking everywhere. As long as we use protection, it's fine, right? Let's see what else this hypnotized little sister will do for me.
