On this date in 2007, Kathy L. Washington of Aurora, Colorado received a U.S. Patent for her invention, “a lubricating sexual aid”. The “invention is selectively insertable into an orifice of the human body such as the vagina or anus in order to stimulate sexual pleasure of the user.” The device includes a syringe-like plunger assembly which allows a user to deposit “lubricant within the orifice while the aid is being used.” Courtesy of SexPatentsTheBook.com.
