Kendall Jenner is definitely comfortable in her own skin.
The 22-year-old runway model and Keeping Up With the Kardashians star took to her Instagram Story on Monday to share a short video to show off washboard abs and super toned legs.
The svelte reality star flaunted her flawless physique -- and stayed cool in the sweltering summer heat -- in a tiny, lime green bikini, which she wore around her luxurious estate.
Jenner, who filmed the clip in front of a reflective glass door, captioned the pic, "BFF with this window," in a font color that matched her two-piece swimwear.
Jenner shared a similarly sultry bikini snapshot to Instagram late last month.
The clothing entrepreneur modeled a canary yellow bikini, which is part of the swimwear line sold by Kendall + Kylie, the clothing line developed by her and her sister, Kylie Jenner.
