Sasha Grey: 'Anal Artists' Porn Co. Exploited Me AND Read Across America

Sasha Grey insists she had nothing to do with a "pathetic" porn company's attempt to donate proceeds from its new film "Anal Artists" to Read Across America -- telling TMZ, the company's trying "to capitalize on Read Across America, controversy, and my name."

Assence Films announced it was donating proceeds from the film to Reading Across America in support of Sasha's "recent efforts to expose children to the world of literature" -- but Sasha says she's never even heard of the company.

Sasha tells us, Assence is exploiting her by trying to "re-package and re-sell an outdated, previously-available scene by touting it as one of my last scenes."

But Sasha doesn't know what's worse ... "the fact that people are now misled to believe I’m personally selling this movie with salacious marketing, or the fact that the [National Education Association] won’t take donations from this pathetic company."

Sasha adds, "There’s little money for education in this beautiful country, and as a pro-education advocate, it’s heartbreaking to hear this."

TMZ broke the story ... Grey -- who once won a Best Oral Sex award for her role in "Throat: A Cautionary Tale" -- participated in Read Across America at Emerson Elementary School in Compton, CA back in November.

Sadly, Sasha says the program has since been shut down at the school "because of one lone disgruntled fan who harassed my parents, the school district, the media and me, for my involvement in such an important program."
