The tag "suck-black-cock" is a description of a specific type of adult content. Let me break it down for you:
1. Suck - This refers to the act of performing oral sex on someone else, specifically focusing on their genitals. In this context, it is referring to the act of a person (usually a woman) orally pleasuring another person (typically a man).
2. Black - This word in this context indicates that the person performing the act (sucking) is black or has a dark complexion. It could also imply that the person being sucked is black, but it's more commonly used to describe the performer.
3. Cock - A slang term for a man's penis. This word is generally used in adult content and among adults discussing sexual acts.
So, when you put these words together as a tag, "suck-black-cock" is describing a specific type of pornographic video involving a person with a dark complexion performing oral sex on a man's penis.
