Kendall & Kylie Jenner Look Amazing in Their Bikinis!

Kendall Jenner makes her way to a boat to go sailing with her sisters on Tuesday (August 18) in St. Barts.

The 19-year-old bikini-clad model was joined by her sister Kylie, also in a bikini, as well as Khloe Kardashian and Kourtney Kardashian, who brought along her son Mason (not pictured).

The family was reportedly set to go parasailing that day! Kim Kardashian was pictured earlier in the day getting in some exercise on the beach.
