If you're too shy and/or lazy to go out and find a partner to wield a paddle for you—and if a Fucking Machine or Sybian doesn't quite take care of the particular itch you're trying to scratch—might we interest you in The Robospanker, "the world's first robotic spanking machine"? Since its introduction in 1997, the Robospanker has gone through several refinements, and the latest model includes features like quieter operation and "light spank mode", presumably for when you're not feeling that naughty. Ain't technology grand?
