My step brother joined the service and deploys in a couple days. I've wanted to see and touch his cock for so long. I know he films me with his phone when I'm in the shower. I leave the door unlocked hoping he comes in to watch me. We've never talked about it. It's been years of flirting. I've thought about doing very naughty things with him behind my parents back. Well, now I'm legal and he’s leaving. This is my last chance to have some of my big step-brother before he leaves. He’s going to serve our country, servicing him is the least I could do. Right? I confronted him in my room. He wanted it as much as I did. I pulled out his swollen step-brother dick and squeezed it hard as I ran my hands up and down. It was so thick and made my young tight pussy instantly wet. I showed him my titites and stroked him until his legs twitched. I got completely naked and straddled him so he could see my hairy tiny pussy.
