'We Were Up All Night'...Kris Jenner's Sex Talk Embarrasses Daughters Khloe and Kendall

Kris Jenner is sex-positive and doesn't care if it completely embarrasses her daughters. 

The reality star, 64, arrived late to lunch with Khloe Kardashian and Kendall Jenner and proceeded to talk openly about her love life, as seen in a teaser for the next episode of Keeping Up With The Kardashians.

Turns out only moments earlier, Kris was making out with her boyfriend Corey Gamble, and was wondering if they could tell.
