When the going gets tough, the tough get . . . raunchy! With her marriage in full-on crisis mode -- estranged husband Lamar Odom briefly entered and exited rehab last week -- Khloe Kardashian isn't having the easiest time of it lately. The 29-year-old reality star is getting through it, however, with family -- and laughs! On Sunday, Sept. 8, Kardashian took a breather from the drama with 17-year-old sister Kendall Jenner to pull off an X-rated prank on youngest sibling Kylie Jenner, 16.

The mischievous sisters hijacked Kylie's Twitter account with a series of shockingly raunchy posts for all 4.6 million of Kylie's followers to see. "My d--- hurts . . . Someone lick my b---- NOW!!! . . . My t--- are so massive they get in the way on twitter. Who can relate?" the gasp-inducing missives read.

The piece de resistance was a nod to the trio's second eldest sister, new mom Kim Kardashian: "I love wearing Kims breast pump!! Yummy the smell of sour milk"

In a grainy Keek video, Kendall (with Khloe seemingly in the background, hunched over a computer screen) cracks up over punk-ing Kylie.

Getting wise to the the joke, Kylie wrote: "I just love when @KhloeKardashian and @KendallJenner hack my twitter . . ." But Kendall and Khloe weren't done with their fun just yet.

"I am not hacked I am just having major issues with my male and female self. A bitch with b---- ," subsequent joke-tweets read. "Bitch with a d---. Best of both worlds."
