Venus 2000 milking machine

This is an electrically powered stimulation device for men. The user inserts the penis into a cylindrical plastic attachment. Changing air pressure creates an automatic sequence of movement that feels like a rhythmic massage. The user barely has to do anything and can lean back and relax.

The device can be used in various positions. A dial adjusts the speed smoothly, from very slow to fast movements per minute. The suction can also be set individually to vary the intensity of the massage.
