My stepbro caught me fucking in the house and I had to fuck for his silence

Me and my stepbro have strongly forbidden to bring people to the house, even more, having sex here.<br><br>I brought my boyfriend over to fuck in the livingroom while nobody was home, I thought my stepbro wasn't here either, but he was, and not only did he realize that I was having sex in the house, but he recorded me doing it, and told me that he was gonna send the video to our parents if I didn't fuck him, so I had to fuck for him to don't say anything.
