Old prostitutes are picked up off the street, or in the case of an agency, they are lured into a motel room by a very attractive young man who claims to be "testing" her. She is left alone in a room with two other women while he proceeds to give her oral sex. As she does this she is given fake orgasms by using her vagina. This is how she earns her money. The next day she returns to her job as a prostitute and is promptly paid for her services. While her service is not particularly sexual, it is the same as the women who get "tested" for prostitution, and those women are generally younger and less experienced than her..
