Fucking Machines is a pornographic website founded in 2000 that features video and photographs of women engaged in autoerotic sexual stimulation with penetrative sex-machines and sex toys. Based in San Francisco, California, the site is operated by Kink.com. Web entrepreneur Peter Acworth launched Fucking Machines on September 25, 2000, as his company's second website after Kink.com. Devices shown on the site were created with the intent to bring women authentic orgasms. Performers were instructed to allow themselves to be recorded experiencing pleasure.
