START-255 Revenge for the King of Our House When I gave my sister a 100x more concentrated sexual desire booster in order to take revenge, she fell into a slutty, weak pussy, and despite her younger brother, she got an erection. Kamiki Rei

I hate my sister. After my father was laid off, my sister's income became our family lifeline. From then on, my sister became the king of our family, and the whole family became servants. I concentrated 100 times the dangerous libido booster I had given me from a friend and administered it to my sister, half as much as a joke, and she lost her pussy. Although I'm a younger brother, I got an erection.
