The fuck machine is set up nearby, its mechanical components visible and ready for use. The user applies lubricant to the machine's dildo attachment and to their own body, ensuring a smooth and pleasurable experience. They then position themselves so that the dildo is aligned with their desired entry point, whether it's vaginal, anal, or oral. The user starts the machine, often with a remote control or a dedicated switch. The machine begins to move, its mechanical arm or piston driving the dildo in and out in a steady, rhythmic motion. The user can adjust the speed and depth of the thrusts according to their preferences, using the controls to intensify or ease the sensations.
