Bukkake is a group sex practice wherein a series of men take turns ejaculating on a person (often a female). There are strong overtones of erotic humiliation in this practice. Usually in bukkake videos, a beautiful young girl will sit and allow a group of men (sometimes more than a dozen) to come up to her and openly masturbate until they ejaculate on her body (usually on her face and mouth). The girl leaves the semen on her face as another man comes to repeat the routine. Often the scene ends with the girl swallowing the semen gathered. Producers of these films often attempt to find men who ejaculate a large amount. Often in the background of the these videos, men who are waiting for their turn can be seen masturbating to keep themselves erect.
