Satisfying my desires with my stepsibling

I've always had a thing for my stepsibling. Not in a weird way, but their body, the way they move, it just does things to me. So, when we were alone one night, I decided to take a chance. I started touching myself, hoping they'd notice and join in. Luckily, they did. We got really close, their fingers exploring my body, their mouth on my most sensitive spots. It was amazing, like nothing I've ever felt before. Then, they took out their cock and I knew what I had to do. I gave them the best blowjob of my life, my mouth working their hard cock until they came. It was a sight to behold, their cum splattering all over my face. It was the best moment of my life, and I know it won't be the last.
