Anna Katharina Arches Her Back, Flaunts Voluptuous Chest & Perfect Derrière In Tiny String Bikini

Instagram hottie Anna Katharina reminded her 1.3 million Instagram admirers why they follow her Tuesday. She shared an update that featured the model flaunting her smoking-hot body in a tiny string bikini.

Anna's skimpy two-piece was a pale pink, which made her tan skin pop. Her voluptuous chest filled the triangle-shaped cups, leaving most of her breasts uncovered. The number had a gold detail along the bottom edge that drew the eye to her chest. The bottom was equally revealing with a low-cut front and thin straps that sat low on her hips. Each piece featured a small ruffle, giving the swimsuit a feminine touch.

The buxom blond wore her thick hair parted off center and down in big waves. She also sported a bold white polish on her nails.

Anna's update consisted of three snapshots that captured her striking sexy poses. She appeared to be standing on a deck with a pool behind her. Her bronze skin appeared to be dewy, adding a sensual vibe to the pictures.

The tantalizing images got Anna's fans buzzing, and judging from their responses, they loved the look.

"OMG. What an amazing bodyshape!" one enthusiastic admirer wrote.

"You are very sexy and beautiful," commented a second follower.

"You are fabulous," a third Instagram user chimed in.

"Most. Beautiful. Woman. Alive," quipped a fourth fan.

In the first slide, Anna gave her followers a nice look at her flawless body with a titillating side pose. She stood close to a door and arched her back slightly, accentuating her tight abs and shapely thighs. With one hand on the door, she turned toward the camera and looked off to the side with a sultry expression on her face.

Anna showed off even more of her booty in the second photo, which captured most of her backside. She leaned her head against the door with a big arch in her back. The pose displayed her perfect derrière. With her hands on the straps of her cheeky bottom, she also gave her followers a good look at her bustline. She looked over her shoulder and gave the lens a provocative look.

The third picture caught Anna from a front view. She stood at a slight side angle, accentuating her flat midsection and the sexy curve of her hips. The snap showed off the model's ample chest. Sunlight from behind highlighted the small of her back. With her head tilted down, she gazed at the lens while her long hair fell over her shoulders.

Anna gives her online audience plenty of content to enjoy — and most of it puts her incredible figure on display. Earlier this month, she flaunted her curves in a tiny crop top and pair of short shorts.
