Today my stepbrother, Derek, needed a massage to get ready for the championship. We both stripped down to our underwear. I grabbed the lotion while he relaxed on the massage table and started working his shoulders and lower back before moving on to his firm ass. It had been a while since I had touched his ass. Usually just a smack at the end of a stroke, but not like this. I heard him groan as I moved, so I took a chance and started playing with his hole. I could feel it pucker and open for my finger. By this time my cock was rock hard, and I had to let it free. I walked to the front of the table, pulled it out, and Derek knew what to do with it. I pulled it out of his mouth, walked over to his feet, and squeezed my cock between them. After rubbing my cock against his ass, I shot a load all over his face.
