Fuck machine

A fuck machine is a mechanical or technical device used to simulate intercourse or provide sexual penetration with an artificial penis or dildo. Depending on the design, it may create vibrating, rotating, or thrusting movements. Historically and in pornography, the term is used for different devices intended to automate or intensify sexual stimulation.

Using such devices can involve significant physical pressure, friction, and injury risks. They should therefore only be used with suitable caution, appropriate attachments, careful hygiene, and clear control over intensity and movement. Sensitive areas, mucous membranes, and unsuitable materials require particular restraint; if pain or uncertainty occurs, use should be stopped.
