Wearing her raven tresses loose, Kourtney was a total beach babe in the skimpy ensemble as she switched between sunbathing and dipping in the water.
The eldest of the Kardashian clan sizzled in her barely-there two-piece, showing off her enviably taut midriff as she stretched herself out beside Sofia.
The star, who was already of voting age when Sofia was born, opted for a sleek black bathing suit that complemented her sleek double-bridge shades.

Ever the natural beauty, the mother-of-three opted for a make-up free look, as she played with her kids of the idyllic waterfront.
Meanwhile, Sophia, the daughter of musical icon Lionel Richie and half-sister of reality TV legend Nicole Richie, opted for a sizzling burnt-orange number that played up her chiseled frame.
Kourtney and Scott's two elder children - Mason, eight, and Penelope, six - had their births documented on Keeping Up With The Kardashians.
Kourtney and Sofia seemed to be enjoying each other's company - at one point, as they lounged side by side on deck chairs, the younger woman leaned over and smiled at something on Kourtney's phone.

However, their youngest child, a son called Reign who celebrated his fourth birthday about a week ago, was born away from the cameras amid family drama over his father's drinking.
The trip to Mexico comes after Sofia was said to be 'uncomfortable' after Kourtney shared a photo of Scott and their kids to Instagram.
'But she has been trying not to let it get to her,' added the source to US Weekly.

All the attention Kourtney is showering on family could be creating a rift for Sofia and Scott.
'Sofia is beginning to fight feelings of jealousy as Scott and Kourtney continue to spend more time together,' a source told Hollywood Life.
'Sofia did her best to be cool with Scott’s relationship with Kourtney for a while… She wanted to be the cool girlfriend, which was easier to do when Kourt had a boyfriend,' the insider added.

'But now that Kourtney is single and dating again, Sofia struggles with the time Kourtney spends alone with Scott and the kids.'
'Scott is looking really good lately and it stings when Sofia wants to see her sexy man him but can’t because he is busy with Kourtney,' the source dished.
Kourtney and Scott split in 2015 after nearly 10 years together and both have been playing the field since then.
