I hate my sister. Ever since our father was laid off, her income became the lifeline of our family. From that point on, she became the king of our house, and all of us became her servants. I took some potent aphrodisiac from a friend, concentrated it 100 times, and gave it to my sister half as revenge, half as a joke. She ended up being extremely horny and fell into a slutty state. Even as her brother, I got an erection.
