Serious love with my sister... I love my sister so much that I can't control myself. One day, when I confessed my feelings to her, she asked me, "Do you really regret having sex with me? You might not be able to do things the way you used to..." and made me decide whether to do it or not. Of course, my answer was yes! And she gently accepted my feelings, and for one night and two days without our parents... we forgot about being brother and sister and passionately sought each other... As my sister said, we became a different brother and sister than we were before.
