In the quiet of their home, Manuel's dental practice becomes a sensual playground. His wife, lying back, allows him to run the thin thread of dental floss over her teeth, around her gums, each pass sending shivers down her spine. Manuel, his professional demeanor replaced by a hungry lust, uses the floss to trace her lips, her tongue, her neck, igniting a fire within her. She responds in kind, taking the floss from him, using it to tease him, to explore him, their game of dental desire escalating, their bodies pressing together, their moans filling the room as they lose themselves in their taboo, arousing ritual.
