Tiger Woods Mistress Joslyn James -- I'm a REAL Whore Now

It's the first and last time in your life you'll ever have a chance to score like Tiger Woods -- because one of the girls he banged behind his wife's back in 2009 is now a FULL-BLOWN PROSTITUTE ... but only for one week.

Dennis Hof -- the owner of the Moonlite Bunny Ranch in Nevada -- tells TMZ, porn star Joslyn James (aka Tiger's mistress #8) is offering up her 3-hole course at the famous brothel from December 5-12.

Dennis tells us, "Now you can finally have a piece of Tiger's tail."
