Tanning Mom: I'm Way Hotter Than Farrah Abraham ... And I Do GREAT Porn

Tanning Mom Patricia Krentcil wants more than a sun kiss ... she wants to get plowed in a full-on porno -- for a hefty price.

TMZ has obtained an email sent to Vivid Entertainment's Prez Steve Hirsch, in which the 45-year-old leatherette says, "I see you are trying to buy this sex tape from this Teen Mom. Well, if you REALLY want to make more MONIES, then I would agree to let you film me and all my hotness."

Krentcil, oblivious to shame, goes on: "I am far MORE popular and WAY HOTTER than Farrah!" And there's more ... "Men want a cougar and a real woman, not a teenybopper."

But sex -- and Krentcil -- do not come cheap. She makes it clear to the Vivid honcho, "Contact me back if you're ready to talk serious cash and rock the world."

Sad ending. Hirsch sent a return email, telling T.M., "Unfortunately we don't have a granny porn section on Vivid.com, but we feel your look would be perfect for radio. You could talk about everything you've ever done on a tanning bed."

It's hard for a nice piece of leather to find work.
