Sis porn caught a stepsister watching porn!

The night was restless. I just returned from a party. But when I was in front of my stepsister’s door, I heard a noise. I crept closer, opened the door, and was dumbfounded by what I saw. Left alone in her room , my step sister lay in her bed with her legs widely spread and masturbated her hot pussy. I quickly turned on the camera on my iPhone and started shooting. The thought that I was doing something taboo began to arouse me. I took out my dick, and without stopping filming my stepsister, I began to jerk it off. I was about to cum right at her door, when my stepsister suddenly noticed me. She was not embarrassed at all; on the contrary, she began to moan a little louder and beckoned me closer. Obviously, she really wanted sex, and she did not care that I was her stepbrother.
