She licks the corn cob seductively, her tongue tracing its length, mimicking the act she wants to perform on him. He watches, his cock hardening in his pants, as she takes the cob deep into her mouth, her eyes never leaving his. The tension builds, their breaths growing heavier, as they both anticipate the forbidden act they're about to indulge in.
