Step brother helps me win my bet by masturbating

I was betting that my step brother was packing a huge package, and to my surprise, he didn't disappoint. He had a massive cock, and it was the talk of the town. I couldn't resist the urge to play with it, and when my step brother caught me, he didn't get mad. Instead, he offered to help me win my bet by giving me a handjob. His hands were skilled, and he knew exactly how to stroke my cock to make it explode with cum. It was a taboo situation, but it felt so right. I couldn't believe how good it felt to have his hands on my cock. The sensation was overwhelming, and I couldn't hold back any longer. I released a huge load all over his hand, covering it with my cum. It was a sight to behold, and I knew that this was just the beginning of our naughty adventures together.
