A sex machine, also known as a fucking machine, is a mechanical device used to simulate human sexual intercourse or other sexual activity. It is a more sophisticated version of the vibrator.

Devices can be penetrative or extractive. A typical penetrative machine works by the transfer of rotational or reciprocating force from a motor to a directional motion on a shaft, which is tipped by a dildo. A hand-held modified reciprocating saw device is sometimes called a fucksaw, a hand-held modified drill motor rotating device is sometimes called a drilldo, and a modified jigsaw is called a jillsaw. An extractive device works like a milking machine and can be attached to the penis, breast, or other body part.
