NBA legend Michael Jordan tried to win entrance into Kennedy's vagina during a steamy dice game back in 1995 ... so says the former MTV star, who claims she was a virgin at the time.

Kennedy -- who was a huge MTV VJ back in the '90s -- details the encounter in her new book "The Kennedy Chronicles" ... explaining how she was having dinner with MJ and Russell Simmons at the Bowery Bar in NYC, when Michael broke out some dice.

Before long, Kennedy says, Jordan decided it was "time to play for something" ... and said, "If I win, you come back to my hotel room with me tonight."

Kennedy says she freaked out because she was a virgin --and imagined MJ's giant penis would "eviscerate me from the inside out" ... so she asked if they could play for Knicks tickets instead.

And that's when Jordan allegedly reminded Kennedy he had a wife -- and offered her Nets tickets as a consolation.

"Sure, he'll filet my vag like a sea bass if he won at dice on a men's room floor," Kennedy writes ... "but as soon as I want basketball tickets he's a Promise Keeper? Whatevs."

Kennedy says she won the dice game anyway -- so her vag was never in any real danger.
