The 38-year-old mother of three posted a NSFW clip of herself rolling around naked in a shallow pool. The footage was shot far away and she moves so quickly that you barely see anything, but there’s no denying that the reality star is completely in the buff.

Kourt also Instagrammed a bootylicious shot of herself in a thong one-piece swimsuit, captioning it with the lyrics, “This is how we do it down in Puerto Rico.”

She’s been enjoying the wild festivities south of the border with her sister, Kim Kardashian, and close pals. Kim shared a group shot of the ladies (fully clothed) late Tuesday night with the caption, “Girls Trip.”
