Top Definition
A mechanical device used to simulate human coitus. A more sophisticated version of the much simpler vibrator. The device can be used by females to excite the vagina and by either sex to excite the anus. These devices may be associated with, but are not limited to, BDSM play.

A typical machine works by the transfer of rotational force from a motor to a directional motion on a shaft, which is tipped by a dildo.
Shannon couldn't find a date so she stayed home, strapped a big dildo to her fucking machine and cranked it up to full speed till she couldn't take it anymore !
