In front of the camera, I was frantically masturbating, my vulva spread wide, juices dripping down my thighs. Suddenly, the door was pushed open, and my younger brother, who had brought me water, stood frozen in terror. I shuddered, but became even more excited, thrusting faster and faster in front of him, moaning incessantly. My brother blushed and tried to escape, but I held him back, making him watch his sister's lewd behavior until I climaxed and squirted, splashing him all over.
