Khloe Kardashian couldn't be closer to her half-sister, Kendall Jenner.
Need proof? Well, you've come to the right place.
On Wednesday, the 31-year-old reality star shared a snap on Instagram that showed her licking Kendall's abs– although the supermodel just bared a lot more than that in her new Calvin Klein ads.
"I missed her so much and those abs were irresistible!!!!" Khloe wrote.

After all, Kendall has been busy modeling at Paris Fashion Week.
Awkward? Perhaps. But not nearly as much as when Khloe asked her brother, Rob Kardashian, to take a photo of her from behind, which she posted and wrote, "That awkward moment when you make your brother the photographer lol!"

These siblings just keep showing off their love for each other.
On Wednesday, Khloe and sister Kim Kardashian were there for their older sibling, Kourtney Kardashian, who just called it quits with her longtime boyfriend, Scott Disick.
The trio had a girls' night out after filming an upcoming episode of Keeping Up With the Kardashians at Casa Escobar in Westlake, California.
