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 !
