EXCLUSIVE

Crack-smokin' Toronto Mayor Rob Ford may not look like a sex god ... but at least two adult film companies want to turn the mayor into a porno superstud ... sources in the XXX biz tell TMZ.

We've learned Vivid Radio is making an offer to Ford to star in his very own sex video. Vivid star Brandy Aniston says she came up with the idea ... and wants to co-star in the flick because she thinks "He's kinda cute, in a big, teddy bear kind of way."

Brandy better hurry up, because spoof porns are already being shot.

Adult website woodrocket.com ... has already produced a porn parody of the mayor's binge drinkin', crackalackin' life. It stars a Ford lookalike-- whose porn name is Peter O'Toole -- and porn actress Gaia ... who's starred in such classics as "Slurpy Throatsluts" and "Happy Tugs 4."
