It's a tough job, but someone's got to do it! Kendall Jenner and Kylie Jenner shared pictures of their semi-naked photoshoot with a bevy of handsome, shirtless male models on Monday, June 30.

Kim Kardashian's little sisters posed with beaming faces as they were lifted into the air by two of the hunky boys, while three other muscular men knelt at their feet and posed for the camera.

Keeping quiet as to the reason for the pictures, Kylie, 16, teased jealous Instagram followers with the caption, "Model boys, ladies.. model boys!"

One of the models in question, Mark Fisher, revealed on his Instagram account later in the day that the snap was taken during an organized photoshoot, but not what the shoot was for. "Great shoot today with the Jenner sisters," the buff model wrote. "Really nice girls," he added.

It’s the latest in a string of jobs for 18-year-old Kendall, whose star is rising in the modeling world. The brunette beauty looked stunning in a recently released Givenchy photograph for their fall 2014 campaign. Previously she walked runways for Marc Jacobs at New York fashion week, and Givenchy at Paris Fashion week.
