My little stepsister is too cute to resist... I repeatedly spy on her, and even after being caught, she proposes an alternative to being forcefully inserted into, saying "No... just my mouth is okay..." From then on, every night I sneak into her room and ravage her oral cavity. However, with each oral assault, she becomes increasingly wet, and eventually whispers a new desire: "Big brother, not just my mouth..." The daily blowjobs pay off, and finally, the long-awaited insertion into her cavity is realized!
