Aussie bikini blogger displays a breath taking massive curve and boob with huge cleavage

The brunette Australian sex symbol left her 1.2 million followers' tongues hanging with a series of sizzling swimwear snaps from her vacay in Cancun.

One of the pics sees her wade into the surf in a burgundy string two-piece, which looked as though it could be obliterated by an incoming wave.

In another shot she reclined by the pool with her hair slicked back, offering up a generous glimpse of sideboob in the tiny top.

And third, taken from the waist up, revealed the beginnings of an underboob eruption as the vixen's assets made a bid for freedom.

"OMG those curves are off the chart," one user gushed in the comments section, while another added: "Hottest girl on Instagram, hands down".

Still, the pics are as much about business as pleasure. The bombshell has combined her sex appeal and keen entrepreneurial senses to launch a blog that has taken the world by storm – A Bikini A Day.

With a huge social media footprint, an online store, the Monday Swimwear label and look books with top designers, its safe to say that Devin is a pose hard, play hard kind of girl.

But it hasn't always been easy for the pin-up.

Before the brand took off, the stunner had to share a bed with BFF and co-founder Natasha Oakley because she couldn't afford a place of her own.
