PINKY SAYS SHE WOULD DO PORN WITH MYSTIKAL BUT NOT PAY HIM!

Rapper Mystikal's porn career is off to a promising start -- TMZ has learned, Mystikal's #1 porn star crush has AGREED to have sex with him on film ... but he better not plan to get paid for it.

XXX star Pinky -- who Mystikal named as his top choice to pop his porn cherry -- tells TMZ, she's flattered the rapper picked her ... and will gladly film a sex tape with him for her website.

But Pinky says she refuses to pay him -- because Mystikal is currently an "amateur" and Pinky doesn't pay amateurs ... "no matter how good he is in bed."

As we first reported, Mystikal says he's taking one last stab at the music biz before he gives up and turns to porn ... seriously.

As for his six-year prison stint for sexual battery, Pinky says it doesn't bother her one iota -- telling TMZ, "I think he came out looking better than when he went in."

Sometimes she reminds me of this
