"Lickable nipples" is a term used to describe female breasts that are considered visually and tactilely pleasing for oral stimulation. In the context of pornography, this tag often appears in titles or descriptions of videos featuring explicit content involving women's nipples being licked, sucked, or otherwise orally stimulated by either a partner or themselves (using a sex toy). This tag is meant to indicate that the video will feature such activities and may appeal to viewers who enjoy watching or fantasizing about this specific type of sexual interaction
