Tough competitor: Nina gave a glimpse of her black lacy bra as she got stuck into the game against her fellow models
She also wore a black bikini top and a cut-out white vest with her surname on the back, ensuring that she was the centre of attention.
And the relatively unknown blonde was lapping up the attention, gamely posing for pictures and ensuring that a great deal of her toned bottom was on display in her barely there bikini bottoms.
Her long blonde hair was loose around her shoulders and she made her long legs even longer by wearing a pair of trainers with a hidden lift.

The 23-year-old blonde is currently vying to win SI’s Rookie Of The Year award.
While Hoopes was out to get noticed, Agdal, 21, appeared more interested in showing off her skills.
The more famous of the two models threw herself into the game and laughed uproariously when she ended up on her bum in the sand.
The rookie: Hoopes definitely made a name for herself as she competed with established models such as Agdal
She wore a backwards baseball cap over her long hair and didn’t appear to be too worried about getting covered in sand.

All the competitors enlisted a sponsor for the charity event, which raised more than $20,000 for the Armed Forces Foundation, an organisation that offers assistance to active-duty and retired military personnel.

Lily donned tight black exercise leggings with a white vest and pink bra top. She allowed her long brunette tresses to flip freely around her face as she played.

The photographer is based in Miami where she loves to capture every day life as well as fashion.
On her blog she writes: Whether it’s the warmer climate, the turquoise water, the pastel buildings, or the breathtaking sunsets, there is just something about the Magic City that seems to inspire everyone.
‘I hope to candidly showcase both Miami’s fabulous fashionistas and funky freaks in their natural habitats, with a major emphasis on the city herself as a main character.’
She photo bombed the Sports Illustrated Swimsuit Beach Volleyball Tournament models and players group shot but was quickly removed and threatened with arrest if she did it again.
However, that didn’t appear to upset her as she sported a huge smile while being led away by a burly security guard.
