Distantly, there is a bit of sensible fear at the strength of her emotions, the desire she feels for him, but for her, fear has never been a reason to run away.

Her head curls towards the touch of his lips. She closes her eyes, shifting as she tilts her hips to receive him. Her voice telegraphs her pleasure, a low sigh that grows to a decadent moan.
