Before leaving her luxurious vacation in Mexico, Kourtney Kardashian made sure to post a sexy selfie of her in a skimpy black bikini top. However, the top hardly contains her ample breasts. 

Now, let's be real. It wouldn't be a Kardashian vacation unless someone posted a cleavage-baring selfie before heading home, so let's not hate. This time, it just so happens to be all about Kourtney. 

Sporting some pretty hot shades, and letting her hair hang over one shoulder, Kourtney looked natural as she posed for the photo, writing "gracias Mexico." 

Kourtney, Scott Disick and their two children, Mason and Penelope, returned home on Saturday -- they were seen walking through LAX. 

It seems like Kourtney is really missing Mexico already because she posted a photo from their vacation on Monday, Jan. 27. 

Kourtney and her family were staying at Girls Gone Wild creator Joe Francis' beach-side Casa Aramara retreat in Punta Mita, Mexico.

The luxurious 40,000-square-foot property has hosted celebrities like Jennifer Aniston, Eva Longoria, Demi Moore, Lady Gaga, and Charlie Sheen.
