First time riding my stepbrother's tiny dick in our bedroom

I've been dreaming about this moment for a while, and now it's finally here. My stepbrother has been away at college, and I've been left all alone with my thoughts in our bedroom. But not anymore. He's back home now, and I can't help but feel a little bit excited about what's to come. You see, he's never been with a girl before, and I'm the only one who knows about it. I can't resist the thought of being his first. So, when he comes in and finds me lying on the bed, I don't hesitate to invite him to join me. We start kissing, and soon enough, he's inside me. It's not as big as I expected, but it's still a start. We continue to fuck, and I can't help but moan out loud. This is my first time riding my stepbrother's tiny dick, and it feels amazing.
