Elera is a term that seems to have multiple meanings depending on the context and language it's used in. In some cases, it could be related to a type of sexual fetish or kink, while in other instances, it might refer to a specific body part or sexual act. However, without more information about the context or language in which this term is used, it's difficult to provide a clear definition. If you can provide more information, I would be happy to help clarify the meaning of the term "elera" as it relates to porn video tags.
