'Pitwash!': Suki Waterhouse Flashes Underboob As Cara Delevingne Licks Her Underarm

Suki Waterhouse is more carefree than we thought as the model clearly has no problem with her close friend Cara Delevingne licking her underarm – sort of - all the while flashing underboob in a skimpy bikini.

The models had either just stepped out of a shower or wrapped up a photoshoot as they can be seen soaking wet with Cara, 21, wearing a black bikini and Suki, also 21, flaunting her enviably slim figure in a green cut-out bikini.

However, it's their daring pose which raises eyebrows with Suki raising her arm, giving Cara free reign to stick her tongue out pretending to lick her model friend's armpit. “Pitwash,” Suki simply captioned the selfie. Lovely!

It was clearly an exhausting day as the girls then snuggled up for yet another photo in bed with a beaming Suki wrapped up in Cara's arms as she, once again, sticks her tongue out licking the side of Suki's face.

It's not the only selfie Cara had taken today with the supermodel sharing a rather racy 'belfie,' no doubt taking inspiration from Kim Kardashian, showing the camera her bum while wearing a sheer black Burberry skirt. “Bottoms up @burberry #shanghai,” Cara tweeted.

Missing from the love-in earlier today was Cara's girlfriend Michelle Rodriguez whom she holidayed with last month, packing on plenty of PDA action.
