Kendall Jenner went the extra mile when working for her half-sister Kim Kardashian in a new campaign shared on Friday.

The 25-year-old supermodel showed off her bare bottom in an extremely racy image that is not safe for work as she modeled black lingerie for Kim’s limited edition SKIMS range that goes on sale on Valentine’s Day.

On the SKIMS website, the Vogue favorite was seen laying on her stomach in a pink room as she exposed her bare bottom by hooking the back of her G-string underwear on her high heels.

Naughty pose: Kendall Jenner went the extra mile when working for her half-sister Kim Kardashian in a new campaign shared on Friday.

The image was eye popping as that type of pose is not standard among SKIMS models.

Usually the models do not show any nudity.

Kendall was on her tummy in a room with plastic pink curtains as she had on a black bra. Her bottom was complete exposed with the strings of the undies on her pointy stiletto perspex heels.

The siren was beautifully made up with neutral tones and a light beige glossy lipstick with her hair worn down over her back and to the floor. Tiny gold earrings sparkled.

Jenner is known for showing off her body for photo shoots for Versace and Vogue.

And the social media dynamo has also worn very little for portraits she has shared to Instagram where she has a stunning 151million followers.

Recently she posed in a string bikini while on vacation with Kylie in Mexico.

Most of the new SKIMS shoot saw Kendall in red lingerie with sisters Kim and Kylie. On Friday Kendall took to Instagram to push the line as well as she shared several images with the caption, ‘Vday is coming BTS from @skims.’

It is a limited edition capsule collection, Kendall pointed out.

In 2016 Kendall told W magazine she loves to go nude and how she supports the Free The Nipple movement.

‘I really don’t see what the big deal is with going braless. I think it’s cool and I really just don’t care!’ Kendall shared. ‘It’s sexy, it’s comfortable, and I’m cool with my breasts. That’s it!’

Later she added, ‘Lately, it’s like I’m either braless or I have my bra out. I’m all about freeing the nipple. […] I just think it’s cool to show off what’s under your shirt — whether that’s a cute bralette or just skin.’

Heating up: The looker was joined by SKIMS founder Kim Kardashian as well as her younger sister Kylie Jenner for a red hot SKIMS shoot shared to Instagram on Friday morning

Her sisters were just as seductive in the new photos but they did not go nude.

Kim stood front and center in a fiery red bra with matching high-waisted briefs ahead of the February 14 launch of her latest collection.

Her impressive abs were on display in a cheeky thong bikini bottom as she seductively licked whipped cream off her fingers.

Kylie didn’t miss a moment to show off her figure as she crawled on the floor near a SKIMS heart-shaped cake.

Sweet things seemed to be the theme with various frosted desserts on hand for the women to indulge.

Kim swapped out her bright red set for a white bra and bottoms as she revealed ‘sexy details’ in her latest line.

‘Introducing a limited edition capsule of super sexy and fun intimates,’ one shot was captioned as Kendall crouched down.

Her endlessly long legs were highlighted with cheeky briefs and a pair of clear plastic heels.

Kylie, a makeup mogul in her own right, sprawled out across a scarlet hued couch as she modeled pieces of black lingerie.

She brought a red heart lollipop to her lips as she threw her arm back in the ‘buttery soft’ set from her sister’s line.
