My super Ke'ai little sister loves me as a man, not as a brother, and I'm her type as a woman... Since we're brother and sister, I tried my best not to cross the line, but my sister invited me by saying, "If we hide under the covers and kiss secretly, it'll be our little secret," so we got into bed together and, nervously, we kissed secretly! Once we kissed, we couldn't hold back and we kissed passionately. And it developed into a forbidden brother-sister sex! My sister was quite naughty, and while we were kissing passionately, she asked me to cum inside her many times in the cowgirl position!
