Gang bang

A gang bang is a sexual activity in which one person is the central focus of the sexual activity of several people, usually more than three, sequentially or simultaneously. The term generally refers to a woman being the focus; one man with multiple women can be referred to as a "reverse gang bang". The term has become associated with the porn industry and usually describes a staged event wherein a woman has sex with several men in direct succession. Bukkake is a type of gang bang, originating in Japan, that focuses on the central person being ejaculated upon by multiple male participants.
