Kim Kardashian West’s bikini tour of Mexico isn’t slowing down anytime soon. After showing off her incredible body in a vintage Dior bikini, the mom-of-two stepped out in a thong bikini and plunging lace-up crop top, flaunting her gravity-defying rear in the skimpy bathing suit.

The 36-year-old was all smiles while frolicking around in the grass with her big sister in a braless low-cut top that was tied up with a knot, showing off her enviable abs. She paired the risqué top with an even more revealing bottom, and topped off her look with a pair of futuristic-looking reflective sunglasses.

As for the antics on their vacation, well, they aren’t any less scandalous. On Monday night, Kardashian West took to Twitter to give a “play by play” of the trip so far, and it sounds like this girl squad is letting loose. The birthday girl Kourtney Kardashian “threw up in her bed 4 times and slept in it,” while Jen Atkin spiked Kim’s oreo shake “to try to get me not to eat it because she’s fat shaming me.”

Oh and Kourtney won’t stop doing “naked cart wheels,” so there’s that. And as for Kim, she’s staying out of the shenanigans. “Oh and as for me you ask? …I’m just sitting here on the beach with my flawless body.”

Let the bikini-clad antics continue.
