"In honor of @styledbyhrush birthday a month ago LOL," Kardashian wrote, along with the clip of herself twerking in a pool. "She taught me how 2 twerk on this trip so [I'm] posting it for her."
The mother of two didn't just twerk to celebrate friend Hrush Achemyan's birthday. She also made the trip to Mexico into a family vacation, bringing 3-year-old daughter North and 8-month-old son Saint along, and even threw Achemyan a little impromptu party.
Kardashian's assistant, Stephanie Sheppard, traveled with to Mexico as well and shared some equally scandalous photos to Instagram, including a few that showed Kardashian rocking a sheer t-shirt but no accompanying bikini top as they frolicked on the beach.
While Kardashian has been extra generous in sharing sexy pics with her followers while in Mexico, the Keeping Up With the Kardashians star recently hinted it's about to get a whole lot racier.
"Have I posted a nude selfie since I lost all my baby weight?" she teased earlier this month. "I don't think so. Get ready!"
"[I post nude selfies] because I feel good about myself," she explained. "You can just get so caught up in not wanting to be motivated, so I made it a really important thing for my confidence and for me to feel good."
