Kendall Jenner and Kourtney Kardashian host bikini-clad Memorial Day party for girlfriends

Kourtney Kardashian and Kendall Jenner had quite the Memorial Day!

The sisters hosted "Kamp Kourtndall" for their girlfriends on the Monday holiday, during which the bikini-clad bunch soaked up the sun during a variety of fun activities.

After a morning tea tasting, the crew participated in a group workout session, had a water-gun fight, played Uno and tanned by Kourtney's picturesque pool. Kylie Jenner's best friend, Jordyn Woods, was there, as were Sarah Howard and music duo Simi and Haze.

Kendall and Kourtney shared a slew of photos from the fun-filled day, for which Kourtney rocked a teeny hot pink string bikini and Kendall donned a high-cut blue-and-red two-piece and her signature tiny shades.

Also there? Kendall's fierce looking Doberman Pinscher pup, who she posed alongside on a poolside lounge chair.
