START-255 Our Home’s King: A Revenge Scheme Gone Wrong. I gave my bossy older sister, who always looks down on others, a 100-times concentrated desire booster as revenge, and she ended up completely overwhelmed. Even as her younger brother, I couldn’t help but be shocked. Kamiki Rei

I hate my older sister. After our father was laid off, my sister’s income became the lifeline of our household. From that point on, she turned into the ruler of our home, and the whole family became her servants. I took a risky libido booster I had been given by a friend, concentrated it to 100 times its strength, and gave it to my sister as a half-joke, half-revenge. She became completely overwhelmed and lost her composure. Even as her younger brother, I was aroused.
