"My big brother, I love you so much!" cries the adorable little sister, easily falling under hypnosis and becoming completely obedient to me. Though she's normally tsundere, once hypnotized, she quickly succumbs, making my heart race with her words. As I unbutton her uniform and start touching her breasts, her excitement builds—when I play with her pussy, she squirts a huge amount. I'm her big brother, but as long as I have a condom, it's fine, right? To think such a cute little sister could become so completely mine!
