XXL cock vs teeny mouth cunt

I just felt like doing something forbidden again. So I grabbed my stepbrother by the hand, went with him into the garden behind the barn so that the others wouldn't see us and started to blow his hot big cock. I was always so horny for him, right from the first day I met him and finally it was time. I knew by chance what he had in his pants when I caught him wanking unintentionally. My pussy always got really wet when I saw him dressed. His part was so tasty and I just couldn't get enough, I sucked and sucked hard on his cock. Suddenly I had to pee so I just dropped my pants and pissed on the floor while I continued to blow. In the end, he kept wanking while I sucked on his balls and then gave me a mega load of cum on my mouth.
