My partner discovered my explicit messages and had rough anal sex with me

I was chatting with a guy on a dating site, and I sent him some explicit messages. My boyfriend found them and got angry. He wanted to punish me for cheating on him. He asked me to come over to his house, and he would do something about it. When I arrived, he pushed me against the wall and forced me to take off my clothes. He tied my hands and my feet with ropes and started spanking my ass. Then, he inserted his big cock into my ass and started fucking me hard. I screamed in pain, but he didn't stop. He fucked me again and again, until I couldn't take it anymore. He dominated me completely and made me his slave. I had never experienced such rough anal sex before. It was a nightmare, but at the same time, it was very arousing.
