Step brother assists me in provoking my boyfriend's jealousy through a steamy encounter

I was feeling a bit bored, so I decided to give my boyfriend a call and see if he wanted to come over. But before I could even finish my sentence, my step brother interrupted me, saying that he had something to talk to me about. Well, I didn't really expect what was about to happen next. He started provoking me, telling me that I was acting too much like a whore and that I needed to stop being so damn horny all the time. But that's not the worst part. He then went on to tell me that he wanted to fuck me right there in front of my boyfriend. I was completely taken aback, but I couldn't help but get excited at the thought of my boyfriend watching me get fucked by my step brother. And guess what? It actually happened! My step brother banged me right in front of my boyfriend, and it was probably the hottest thing I had ever seen!.
