Aside from the drama, the Kardashian sisters can be a lot of fun — as when Khloe and Kourtney got into a food fight!

Kendall Jenner and her younger sister Kylie Jenner appear to have put their dispute behind them – and sealed it with a kiss – after the model uploaded a sexy snapchat video of her younger sister sucking her tongue.

Kylie, 18, approaches her elder sister with her lips out, and as she approaches Kendall’s height, the Victoria’s Secret catwalk model puts her tongue out – directly into Kylie’s mouth.

The video is captioned, “She sucked my tongue… I’m dead.”

While Kylie appeared to be taken aback by her sister’s bawdy prank, she soon found the humor in it and shared the video with her 42.4 million Instagram followers, though she appears to have since erased it.

The sisters are now in Sydney, Australia, promoting their new label Kendall+Kylie. Even though they appear to be friends at public occasions, the two have been clashing on their family’s reality show, Keeping Up With the Kardashians.

A troubled Caitlyn Jenner asks Kendall, ‘What’s the deal with Kylie?’ in one scene from the teaser.

Kendall says to her father, Caityln, in the video, “[Kylie] doesn’t have her priorities straight, and I tell everyone that.”

But that’s just the beginning, as things take an even more dramatic turn as the females engage in what appears to be their most intense brawl yet.

Kendall starts the feud by requesting to borrow Kylie’s favorite brown dress from her closet since she is uncomfortable in her revealing black gown.

“You’re just literally the biggest f—king bitch I’ve ever met,” Kendall said when Kylie refused.
