My Sister

I wish my sister would hook up.

Sometimes I imagine locking the bathroom door, stripping each other's clothes off, and fucking her raw and having my cum pump her and let it drip down while we take a shower. I want to lift her up and have her sit on my penis by having it inserted while we make out.

I fantasize sleeping in complete nude with her. All of this goes away the second I cum, and I feel disgusted for a few minutes but after that want to fuck her again.
