Los Angeles - Kendra Wilkinson was drunk or stoned when she had sex with Hugh Hefner.
The reality television star was just 18-years-old when she entered the Playboy mansion and became one of the girlfriends of Hugh, who has 78 at the time.
Writing in her memoirs as reported by the Daily Mirror, she explained: "I was usually very very drunk during those evenings, I tended not to care about much until the next day. I had to be very drunk or smoke lots of weed to survive those nights."
"At about the minute mark, I pulled away and it was done. It was like a job. Clock in, clock out. It's not like I enjoyed having sex with him."
