Always cold and distant, my little sister suddenly snaps, "Just take it off already!" yanking down my pants and stuffing my cock into her mouth. Claiming she's practicing to get in the mood, she brings her boyfriend home, glaring at me before disappearing into her room. Then one night, she shows up in my room. Though still acting superior, she reveals a needy, affectionate side—sucking me off with a practiced rhythm, yet the intimacy between us grows deeper with every moan.
