Fucking Machine

A machine that simulates the act of fucking / sexual stimulation. Can be used by yourself but also with a partner and are most often powered by electricity. The machines are usable for people with a penis or with a vulva and also have uses for anal stimulation.

These devices are sometimes used for orgasm play as the device will not need a rest and can keep going where a person would have needed a break. The controls are sometimes directly on the device, but often have a controller that allows for a more comfortable position while controlling it for ones-self or someone else. Modern versions sometimes also come with the ability to be controlled by an app on a mobile phone.

These machines can be separated into machines that you can ride like a saddle and others that are actively doing the motion of penetrative sex for you.

Ridden machines

These are commonly linked to brands like Sybian, Tremor or Motorbunny and are specifically designed for a person to sit over like a saddle with different attachments that allow for vaginal or anal penetration combined with vibrations. The person thrust back and some have rotation options for the dildo attachments.

There are also non electric riding machines that allow the person to rock back and forth on a device that mechanically drives a dildo up and down for penetration.

Penetrative machines

These machines are often a type of linear actuator that creates a linear or 'thrusting' motion with an attachment at the end for a vulva, anus or even a penis. The device itself often can be stand alone, but there are variations that connect to other objects like walls or are hand-held.

Attachments for this device also come in all shapes and sizes and sometimes there are attachments that allow any kind of dildo or masturbator to be attached. Some have a single moving rod for attachments, the more expensive models can have 2 or 3.

DIY version of this toy are sometimes converted from reciprocating saw's with an attachment for a dildo but do not contain the same safety and hygiene features build into commercial models.
