My big brother is always obsessed with my ass. He praises it, spoils it, treats me like I'm his special little thing. Sometimes I worry—why is he so fixated on my backside? But that's okay. I'm his obedient ass doll, ready to sway my hips whenever he wants. If it makes him happy, I'm more than willing. This might only be a small part of our daily lives as siblings, but I'd be thrilled if it touched your heart too.
