BIG Brother's self-confessed sex addict Sam Heuston blew her first lover away with a wild romp in a cable car on a Spanish mountain.

Car valeter Mark Kasey revealed how Sam got down and dirty as the cable car went up the Sierra Nevada near Malaga.

"People in other cable cars were pointing and shouting, but that turned her on more. She loved people watching as she did the business," he said.

We can also reveal that Sam, 23, had her wicked way with Hell's Kitchen star Aaron Siwoku, and once propositioned a stunned rugby player with the come-on: "Hey gorgeous, do you give good ****?"

But it was Mark who taught her everything she knows about sex in their three years together.

"I was Sam's first lover and she wanted to learn everything—she'd do any-thing to please me," said Mark, also 23.

He met Sam, from Cheam, Surrey, in 2000, but she spent the first year telling him she wouldn't have sex because she had a spotty back.

"The problem really was that her dad had bought her a boob job for her 18th and she didn't like them. She was embarrassed about how lumpy they felt," Mark revealed.

"When I learned the truth, our relationship moved on."

And after the first time, there was no stopping Sam. "She described herself as a sex addict when she went into the house and I know why," said Mark.

Skimpy

"When Sam is in the mood, four times a night isn't enough for her.

"When we were on holiday in Spain, she wanted it all the time. Once she bent over the balcony wearing a skimpy mini skirt and no knickers. It was so sexy that we did it there and then and she didn't care who saw.

"One of my other favourite memories is when she dragged me down an alleyway and gave me oral sex.

"Even when a man caught us at it, she wasn't put off, she just pulled me into a park and carried on there." Mark was devastated when Sam—a marketing student at Brookes University, Oxford— dumped him. But months later she was begging him to take her back.

First she called him at 3am, pleading forgiveness, then she turned up at his gym. Mark said: "She was hysterical and begged me to talk to her. She just seemed crazy and unstable. I'm glad I found out what a bunny boiler she can be sooner rather than later."

Wild Sam still loves the thrill of sex in public places.

Flatmate Era Alija, 22, said: "If you catch her eye she does enjoy being caught while in the throes of passion. She's definitely had sex in a nightclub toilet. She admits a one-night stand in a park—but moaned about the grass stains on her clothes!"

Another pal, Claire Whitney, 20, witnessed Sam's shocking proposition to the rugby player and said: "The poor lad didn't know what to do with himself."

And Sam's not about to stop. She met Hell's Kitchen's Aaron, 22, at the BB auditions — and they spent the night together.

He said: "She's a really sexy girl and great in bed."

BB BEAUTY Sam Heuston had a one-night fling with Hell's Kitchen's Aaron Siwoku before either starred on reality TV.

Aaron, 22, told friends the brainy brunette was "amazing in bed".

The pair met at the Big Brother auditions in London in March.

Bisexual Sam, 23, was waiting to try out for the show while Aaron was there promoting an internet company. He was knocked out by Oxford college girl Sam, who arrived wearing a figure-hugging pair of pink shorts. The pair later met in London's trendy Five nightclub. Aaron told a friend: "She came to the club then, she came back with me. She was just amazing in bed - absolutely bloody fantastic."

A few days later Aaron had his audition for Hell's Kitchen. The pair haven't been in contact since.

Sam has bragged to housemates that she is "addicted to men and sex".

Aaron told his friend: "She reckons people should be allowed to sleep around. As much as I like sex, if I was in a relationship I wouldn't stand for that."
