My sister "Konatsu" has a bad personality, is rude, and is annoying. She always looks down on me, her older brother. It's also annoying that she has a good face and bouncy F-cup big breasts. Her body has been growing rapidly over the past year, and I've always wanted to violate her... One day, "Konatsu" came home soaked to the bone in a half-naked state after being caught in a guerrilla downpour... I reached the limit of my stress and frustration, and before I knew it, I was confining and raping her... #DickP
