Both girls looked sweet and comfortable in their two-piece bikinis, as protective dad Bruce Jenner looked on. Kylie kept moving around as the paps snapped pictures of the young sisters from a distance. We sure hope they used sunscreen, because the two outdoorsy girls hung out on the beach until sunset with Kendall tweeting:
"Watching the sunset in Hawaii #nothingbetter"
While we always see these sisters playfully argue on their reality show Keeping Up with the Kardashians, they really are closer than anyone. We can't wait until they grow up and give their famous older sisters a run for their money!
