A sex machine is an advanced sex toy used to simulate sexual intercourse or oral sex. Typically, a sex machine has a motor that vibrate, thrusts, or rotates a dildo. Some sex machines may instead have sucking actions and can be placed on the penis, breasts, or clitoris. Many sex machines have varying speeds and intensities which can be adjusted via a control located on the machine itself or a remote.
