My stepbrother and I have a strange agreement. After we have sex, he demands I clean his cum off his shaft. It's a weird arrangement, but one I'm willing to make for the sake of our relationship.
I was just about to head out when my stepbrother called me into his room. He had just gotten done drilling his girlfriend and he asked me to help him clean up. I didn't think much of it at first, but as soon as I got down on my knees in front of him, I realized what he really wanted. He made me suck his cum off his hard cock right there in the middle of the room. I didn't know what to say or do, but I knew that I didn't want my parents to walk in and catch us in the middle of this. My stepbrother is a pretty cool guy and I didn't mind doing it, but I just hope this doesn't become a regular thing.
