My stepsister comes into my room every day, sucking my cock while I remain helpless. She has a gentle and calm personality, but at night her pent-up desires take over, and she repeatedly torments my body. Her hands grip my hips tightly, treating me like nothing more than a tool for her sexual release. Gradually, I become nothing but an object to satisfy her cravings. She pleads with me not to make a sound, and those words crush my heart. Our step-sibling relationship teeters between daily kindness and nightly lust, transforming her into a figure who completely dominates me.
