I don't know my stepdaughter at all! She sent me a video, and I thought it would be something funny. Instead, it was her recording herself sucking her stepbrother's cock! I was never supposed to see that. The whole thing was a mistake, but it was too late to back out now. She had to be grounded. When I confronted her, it seemed like she wanted to be punished. She even bent over and asked me to spank her like the bad girl she was. She knew her video made me hard as a rock. Turns out I like seeing her suck dick. Now that she knew that, she was ready to shove mine in her mouth to get out of trouble. I guess there's only one way to deal with naughty girls. I had to pound her like the slut she is.
