My half sister, I masturbate in front of the camera

my half-sister surprised me in doing something that’s not supposed to do, and now I manipulate it to do what he wants. I recently discovered that she is live porn, and I knew this because he asked me to help her with one of the transmissions. I didn’t want to, I felt uneasy thinking that the thousands of people I have seen naked. But the truth is that I had no choice, my secret was the worst of his. So that I had to disrobe and let her do what she wanted. And this was jerk off. I felt completely tense while she masturbated and has responded to the comments of the transmission.
