Tammy 'Sunny' Sytch is opening up about her '90s affair with Shawn Michaels in the new book she just released -- based on this excerpt, it's clear she ain't holding anything back.

Riverdale Ave Books sent Pro Wrestling Sheet an excerpt from "A Star Shattered: The Rise & Fall & Rise of Wrestling Diva Tammy 'Sunny' Sytch" in which the ex-wrestling star writes about her first kiss with HBK ... and she claims it led to much more.

Tammy says they were instructed to kiss once cameras stopped rolling -- following Michaels' match with her significant other Chris Candido -- and she loved it more than the crowd.

Things allegedly escalated further the next week though, and Sunny goes into far too much detail about Shawn approaching her in a flirtatious manner.  Lets just say it involves Tammy using the words erection, moist and empty locker room.

The book can be purchased at RiverdaleAveBooks.com -- as well as Amazon and iTunes -- and in case you've been living under a rock this week, Sunny also released an XXX video with Vivid where she's sporting her Hall of Fame ring ... a photo of which can be seen HERE.

Check out the full book excerpt and let us know what you think in the comments.
