Kourtney Kardashian and Kylie Jenner are showing off their curves!
The sisters both took to Snapchat on Friday to work what their mama gave them.
Kourtney was first to share a sexy snap on the app, posting an aerial pic of her cleavage.
"Makeup view," she captioned the racy pic, before climbing into a helicopter.

The mother of three also posted a sexy bikini-clad shot on Instagram.
"Island ting," she wrote alongside the black-and-white photo.

Kylie, meanwhile, sported nude undies as she showed off her toned tummy on Snapchat.

While Kourtney and Kylie are leaving very little to the imagination on Snapchat, the sisters were much more covered up earlier this week while rocking head-to-toe burgundy at a family meeting on Wednesday.
