This basically looks like those "Robotic Exercise" machines you see in tanning places these days. Takes all the worry about timing and rhythm out of fucking.

Beautiful, and yet so horribly cold.

That's awesome. =D

Update: So here's the real story about the chair:

Now I have to take my past words back. :P One of my friends sent me a link below. That was a real product, wow! The name is "Dream Love Chair".

According to the site, this chair is not a consumer product. Company sell/rent the chair for particular kind of hotels (Love Hotel), so no retail price could be found.

Thanks to the people of the Sex Drive Mailing List for both the movie link and this extra info.
