The speaker describes her own body, her eyes, mouth and nails, as tools of a trap. Each one looks gentle at first. Her big, doe-like eyes seem soft and submissive, her smile seems sweet, and her nails are painted in soft colors. But under each harmless surface is something dangerous: a predator's gaze, sharp teeth and a "wicked tongue," and nails that can cut deeper than any blade or insult.
The repeated word "tempt" shows what she is doing. She plays the part of prey on purpose, drawing someone close with sweet promises until their warning instincts go quiet. The final stanza is the reveal. Once the person lies willingly at her feet, she will show how wrong they were to underestimate her.
The mood is seductive and confident, with a cold edge of menace. The speaker doesn't sound ashamed of her deception. She sounds proud of it, and the poem reads as a warning about judging by appearances.
