This just got real ... TMZ has obtained graphic images from Farrah Abraham's upcoming sex tape ... and they're way gnarlier than we expected.
The 21-year-old "Teen Mom" star initially denied there even was a XXX tape -- but came clean about its existence last month, after her co-star James Deen blew the lid off her little plot.
As we reported, Vivid Entertainment paid Abraham in the high 6-figure range (nearly $1 million) for getting down and dirty on camera ... and boy does she get dirty ... the pics are intense.
The tape's now called "Farrah Abraham: Backdoor Teen Mom" ... and you can guess why.
