I made my stepbrother stay on the couch but he came back and fucked me mercilessly

After arguing with my stepbrother, I made him stay on the couch so I could have the room all to myself. I stripped completely naked, got into bed to rest until the door opened silently. He came back, looked at me naked, and without saying a word, he started stroking my cock. I got angry and noticed how hard he was. That morning I learned that my stepbrother doesn't take orders he just takes what he wants from my body over and over again.
