Denise Richards plays her in the movie version.

from www.nypost.com – It’s a steamy hot-tub tale even Charlie Sheen would be proud of.

Blond bombshell Sara Leal finally broke her silence about the wet and wild romp she shared with Ashton Kutcher — describing in detail how she had boozy unprotected sex with him twice and was even ready to have a kinky three-way with her pal.

The “Two and a Half Men” star — who lied and said he was separated from wife Demi Moore at the time of their hookup — has great endurance in the sack, she spilled to Us Weekly and London’s Sun newspaper.

“He was good. We weren’t like making love, but it wasn’t weird or perverted,” she said.

Once their first steamy, two-hour sex session ended, Kutcher’s pillow talk included topics like national politics and her religious beliefs.

“He asked about my parents, if they were still together,” she said. “I told him my parents divorced when I was 6. He was like, ‘Let me guess, you don’t believe in love.’ ”

And just as they were ready to go at it again, Kutcher’s bodyguard, bizarrely dressed as a priest, confiscated Leal’s cellphone and deleted texts about the evening she sent to friends.

It all began when Leal and her pal, both bottle-blondes, were naked on Kutcher’s lap in a bubbling hot tub on the balcony of his luxurious Diamond Suite at San Diego’s Hard Rock Hotel on Sept. 23.

That’s when the 22-year-old administrative assistant said Kutcher told the girls he had broken up with his wife Moore, 48.

“Aren’t you married,” asked Leal’s pal, Marta Borzuchowski, who had quickly stripped down to nothing to join Kutcher, 33, and Leal in the tub.

Kutcher was quiet for a few seconds, then replied, “I’m separated,” Leal said.

And technically he was — his wife was 2,851 miles away in New York.

The dripping-wet trio soon moved to his bedroom, where he tried to talk the girls into having three-way sex.

They were still damp and wearing only bathrobes as they sat on his bed, she said. He had only a towel wrapped around his waist.

“Ashton and I started kissing and then he kissed my friend,” she said “He was rubbing my leg and he asked my friend, ‘Would you be comfortable rubbing Sara’s leg?’ And she was like, “Yes.’ ”

He asked if the girls had ever had a threesome. “I said no,” Leal said.

And then nature called.

“I had to pee so I got up,” she said.

“I was so nervous. When I came back my friend was gone. He was like, ‘Well she left. I told her if she was uncomfortable she could leave.’ He was lying down on the bed, so I just laid next to him. We started kissing again. He lost his towel. I took my robe off. Then we had sex.”

She admitted he didn’t wear a condom.

“It kind of caught me off-guard, but we still did it,” she said.

Leal had first noticed Kutcher early that night at the San Diego nightclub, Fluxx. She and some friends later made their way into a private party Kutcher threw at his hotel suite.

When he saw her in his room, Kutcher served Leal shots of booze and mixed her a vodka Sprite cocktail.

He put the moves on her soon after, suggesting she and Borzuchowski join him in the hot tub.

“I started looking for towels,” said Leal. “He just came up and kissed me.”

After they had sex for the first time, the two made small talk, discussing where she grew up and when her birthday was. She also told him that she was religious — a Lutheran from Texas.

“He said, ‘Oh, my gosh, are you a Republican?’ I was like, ‘What, do you like Obama?’ He said ‘Yeah,’ and asked if I could name any up-and-coming candidates. I said Rick Perry.”

Then they had sex again.

“He was like, ‘I enjoy things like this because I’m an actor 90 percent of the time and it’s fake. It’s nice to have moments that are real. I’m here now and you’re here now, enjoying it,” she said.
