A fucking machine is a motor and crank that drive a dildo on a repeating stroke. Speed and depth are set with knobs or a controller. The user positions a harness, a chair, or their own body in front of the shaft and lets the mechanism keep time.

Frames range from a suitcase-sized piston to a full rail bolted to a stand. Stability matters more than peak speed. A machine that walks across the floor at mid tempo is useless. Attachment systems should lock the dildo so it cannot unscrew mid-thrust.

Start slower and shorter than your hand would move. Machines do not get tired and will not notice that your expression changed. A reachable e-stop or a partner at the controller is part of the furniture, not an optional courtesy. Motors get hot. Give them rest.

Setup

• Clamp or weight the base.
• Align the stroke with the body’s natural angle to avoid cervix or prostate slamming.
• Use toys rated for machine torque, not slender novelty sticks.
• Keep hair, bedding, and loose clothing away from belts and cranks.
