I was amazed I could find the image so easily. I have known the phrase "auto-suck car vagina" since I was a kid. I read it in the back of one of the first dirty magazines I ever saw. There was also the "two-fisted sister twister", which was a double headed dildo that rotated in opposing directions or something. These are images and phrases that you just don't forget. The little erotic fiction story in the mag was called "hippy chick bangs horse" and it was not about heroin.
