Kylie Jenner Shows Off Curves in Dream Bikini

 set temperatures soaring as she posted photos of herself modeling her 'dream bikini' on Saturday.

Taking to Instagram, the 28-year-old was promoting her new Khy collaboration with the swimwear brand Frankies Bikinis founded by her friend Francesca Aiello.

In the sizzling behind-the-scenes shots, Jenner rolled around on ground in a tiny black two-piece that just barely contained her augmented chest. 

She also appeared in several other bikinis from the collection, which will be available to buy on July 14. It marks Jenner's second Khy x Frankies Bikinis collaboratin. 

'so fun getting to step into [Aiello's] world again,' Jenner penned the caption of her post. 'there's nothing better than creating with your friends and watching each other do what we love.'

She remarked on how she is 'so excited' for the collection's release, while sharing screenshots of texts she and Aiello sent to one another during the design phase.

In the cover photo for Jenner's Instagram carousel, the mother-of-two was seen wearing nothing else but a black, triangle bikini. 

Another image showed the star lying on the ground in just the swim set and heels while people, presumably working as part of the crew, walked around her. 

One candid snapshot showed Jenner grinning while lying on an inflatable, floating pool bed
