The tag "gay-brother" refers to a specific category within the adult film industry. This type of content typically features two or more male performers who are either actual siblings or portraying brothers in the scene. These videos usually involve sexual acts between the male performers, and are specifically targeted towards an audience that enjoys watching gay porn involving people with a familial relationship. It should be noted that while the characters may be depicted as brothers, this does not imply any form of incestuous behavior as the scenes are purely fictional in nature
