Khloé Kardashian and Kendall Jenner sure look like they're having a lot of fun in the sun!

The sisters Instagrammed pictures of their sexy swimwear Monday, with Kendall rocking a tiny string bikini and Khloé looking like a total bombshell in a plunging black one-piece.

Khloe had some fun with accessories, too—pairing her va va boom beach ensemble with bright red lips, huge hoop earrings and a sequined and bejeweled sailors' cap—complete with a gold chain, of course! The Keeping Up With the Kardashians star shared a selfie of her nautical pinup self blowing a kiss for the camera followed up by a photo of her on a very comfy-looking boat.

Kendall flaunted her model physique, too, showcasing her curves in a string bikini as she was "knocked out in the fiercest way," which appears to be tanning on the boat.

Kendall and Khloé aren't the only ones getting in a little R&R, though! The entire family, including Kim Kardashian, baby North West, Kylie Jenner, Bruce Jenner, Brody Jenner and Brandon Jenner, flew out Wednesday.

From the looks of social media, the Kardashian-Jenner clan is having a blast!
