Australia- THE Territory’s only nudist beach has been taken over by perverts, two teenagers claimed yesterday.

The girls said they were traumatised after spending just one hour at the so-called free beach at Casuarina in Darwin. They went to the beach to sunbake topless.

But they were still wearing their bikinis when: A MAN in his 50s or 60s approached them and asked for oral sex for money; and ANOTHER man began masturbating as he leered at them from the bushes.

The 18-year-olds — who want to be known only as Renee and Kirsten — fled, only to find a couple having sex on the boot of a car. The girls’ nightmare happened about 11am on Monday.

“It was disgusting and made us feel sick,” Kirsten said.

The long-time school friends said they feared for their safety when the first man approached them and asked for sexual favours.

They said he had been watching them from a distance for a while.

“We were having a shower near the toilet block, and he was just standing there staring at us,” Renee said.

She said as they were leaving to go to the toilet, the man followed and asked: “Are you working girls? How much do you charge for a head job?”

Soon after the girls became trapped in the cubicle and could hear the man waiting outside.

“We were really scared and shaking,” Renee said.

They said they finally ran back out to the beach where they had left their belongings. While running they saw a man masturbating in the bush and decided to “get out of there”.

A young clothed man walking on the beach escorted them to their car — to find a couple having sex on their boot.
