This machine is not build yet. It is only a design. But we have all drawings and parts, to build it if there will be an interest.

Pleasure of swinging together on a SWING may be combined with fucking pleasure.

The principle of SWING device - is not a moving dildo, but the body movement against stationary dildo.
The Swing is self-actuated (by the legs force) fucking device, designed for two persons. It is based on a traditional children swing, upgraded to the fucking device, by two dildos, installed under the swing board. Dildos penetrate through the swing board in two holes in seats. The rest is - easy swinging! The frequency and depth are chosen by common intensity.
The SWING set includes swing bord with two seats, mounted on a fiberboard plate, with dildo holders.

Swing&fuck!
