Khloe Kardashian: 'I had sex in the backseat of a moving car'

Reality TV star Khloe Kardashian once had sex in a moving car.

Just days after Kim Kardashian's sister revealed she and her estranged husband Lamar Odom shot a sex tape, the Keeping Up With The Kardashians star is shocking again by opening up about the wildest places she has had intercourse.

Khloe took to her website KhloeWithaK.com on Monday (25Jan16) and revealed she once had sex in the backseat of a car, while it was on the road.

"Don't try this at home," she wrote. "Someone else was driving and I was in the backseat, but I'm a tall girl so it feels cramped and it hurts my f**king knees.

"Getting down in a moving car is a waste of time, because nothing happens for me. I just don't get to the finish line! If you're down for a thrill, then by all means, but this one gets a low rating from me!"

Khloe also revealed she's a member of the mile high club, after having sex in an airplane bathroom, adding, "Doing it on a private plane is great, especially when there are other passengers on board. It's part of the thrill!

"I walked into the bathroom first and then he followed so it wasn't exactly stealth, haha!!! Everyone obviously knew what was going on in and when I walked out, they asked if we had fun."

The reality star didn't mention who she got romantic with.

She also gave counter-top sex in the kitchen a high rating, stating, "You're at home, so it's comfortable, but it's still a little different than the norm. A marble kitchen counter is sexy, thrilling... and cold."
