The past few days has seen her enjoy a joint family vacation to Costa Rica with her sister Kourtney Kardashian and their kids.

And the fun continued for Kim Kardashian on Friday, seen stripping down into a very tiny and risque one-piece for some fun on the water.

The 38-year-old was spotted spending time with her kids while ensuring everyone knew she was a fun mom, making waves on a jet-ski.

Kim proved that her consistent hard work at the gym had paid off, stripping down to a incredibly skimpy one piece with lots of coverage and very minimal coverage.

The suit featured a very high cut bottom and the back and front was all cut out, modestly covering her ample cleavage.

The mom-of-four appeared to be wearing a minimal amount of makeup with blushed cheeks and a ɴuᴅᴇ lip.

At one point, Kim added a blue life jacket to her look and went for a ride with her personal trainer Melissa Alcantara on the jet ski.

Her long brunette tresses were styled out naturally and she struggled to wipe the smile off of her face.

A doting mom-of-four, at one point she was seen giving her eldest son, Saint, three, some special one-on-one attention, cuddling him while he enjoyed a snack.

Saint was dressed in a blue pair of board shorts and sported some colorful, perhaps traditional Costa Rican inspired face paint along with his corn rows.

And as for Kim and Kanye’s eldest daughter North, she was having her own fun, spotted on the jet-ski with Uncle Scott Disick.

While Scott took the back seat and the wheel, the six-year-old sat on his lap attempting to keep a calm face.
