What are sisters for, after all? Kim and Kourtney Kardashian surprise Khloé with an impromptu pampering session on the Sunday, August 28, episode of Keeping Up With the Kardashians, and the youngest of the trio is floored by their thoughtfulness.

The afternoon de-stress session starts out with Kourtney, 37, and Kim, 35, parading into Kourtney’s backyard clad in matching camp-print PJs and carrying several pink boxes of takeout and pastries.

“Kourtney and I want to do something for Khloé, something superchill at the house, just a little pampering-Khloé moment so she feels loved,” Kim tells the cameras.

Upon her arrival, a bemused Khloé can’t hide her surprise. “What the hell is going on?” she asks.

“You’re my second and most honored sister, heir of all I possess,” Kourtney replies.

“Who’s your first?” Khloé demands.

“It’s Kim, she’s the first sister I ever had,” Kourtney says with a smile. “But you’re the honored sister, the heir of all I possess.”

In May, Khloé filed for divorce from her ex, Lamar Odom, for the second time after withdrawing her initial filing following the athlete’s hospitalization last October.

“You just refiled for divorce,” Kim tells Khloé in the preview clip, as Kourtney reminds their younger sister that they want her to feel “adored, admired, loved and cared about.”

A clearly touched Khloé reflects on her sisters’ love in a confession to the cameras.

“This just shows that, you know, my sisters do love me and they are aware of everything I’m going through,” the former Kocktails With Khloé host says. “I do not have a clue what I would do without them. When you have people that you know you can depend on, even though you’re going through s--t, you just know everything is going to be OK eventually.”

Keeping Up With the Kardashians airs on Sundays at 9 p.m. on E!
