It's great to have a stepbrother that's interested in sports. Josh's recently got into the idea of boxing after watching videos of our granddad. He came into my room and already had his gloves on. I grabbed the pad and held it in front of him to punch. Josh’s punches were sloppy, so I moved behind him and helped him out. That was when his ass started grinding on my meat. I reached down and grabbed it. Josh then dropped to his knees and sucked my cock as I lay on the bed. My dick between his lips felt so good, but I also love sucking my bro's meat. We switched positions, and I began sucking his cock before licking his asshole. I was rock hard, and it was time to fuck. We went at it on the bed until both of us nutted.
