Office Fuck--He Threatens to Fire Me if I Don't do What He Says

My co-worker comes to my office. He's angry because he fixed something I screwed up, but I didn't give him credit when I met with the boss. He threatens to get me fired unless I do what he asks and have sex with him. I remind him that I'm straight, but he insists. So we do some sucking, then he asks me to lay him on the desk and fuck him. I shoot a nice, creamy load close to the camera at the end.
