The sisters and their pals rolled around the grass in giant inflatable balls and posed by the pool in their racy ensembles.
“Girls girls girls,” Kylie captioned one pic of the ladies posing with their backs to the camera.
Kylie also cozied up to bestie Hailey Baldwin in a shot that showed off their hourglass figures and tiny hip tattoos. The Jenners’ mutual friend, Camila Morrone, also shared a photo of the ladies from behind with their hands on each other’s butts.
Another pal, Lauren Perez, posted an Instagram of the ladies balancing on top of the inflatable balls, saying, “Girls love balls!”
Kylie Snapchatted some of the group’s antics, taking one video while rolling inside of the inflatable ball.
The newly single reality star has been spotted out with rapper PartyNextDoor lately after her split from Tyga. Last week the new pair went on a bowling date together.
