There's nothing more intimate than family, which is probably why Kim, Kourtney, Khloe, Kendall and Kylie are the stars of Calvin Klein's latest underwear ads. (Well, that and the fact that they're one of the most talked-about celebrity families in the world. It's just smart marketing!)

The five Kardashian/Jenner sisters star in the quintessential American fashion house's Spring 2018 "Our Family — #MYCALVINS" campaign. In the series of rustic photos shot by Willy Vanderperre, the famed reality TV siblings lounge about in their Calvins atop quilted blankets in a barn, cuddling with one another and brooding towards the camera.

In one image, Kendall seems to try her hand at voguing while laying down. In another, Kourtney poses topless while draping a quilt over her chest. Notably (and annoyingly, at this point), in every photo Kylie appears in, her stomach remains covered either by blankets or careful posing—undoubtedly a meticulously planned creative decision meant to heighten the pop culture mythos surrounding the youngest Jenner sister's rumored pregnancy.

See all the photos from the campaign, below:

"The evolved #MYCALVINS concept has family at its center, a display of unity between strong individuals, further emphasized by the symbolism of the traditional American quilt," Klein released in a statement. "This campaign captures these bonds and brings to life different ways we can inspire families—both born and made—to connect with one another, and celebrate the things that unite us."

One bond Kris Jenner's daughters definitely share? Not knowing how to play a proper game of "Never Have I Ever."

In an ad video for the campaign, the Keeping Up With the Kardashians stars rattle off a list of things they've never tried, apparently forgetting that "Never Have I Ever" is actually a drinking game.
