A BARMAN who romped with Foxy Knoxy—the girl student suspected of killing Meredith Kercher—has revealed she was a "wild animal" in bed and HUNTED men for sex.

Elis Prenga enjoyed a marathon sex session with 20-year-old Amanda Knox just weeks before her housemate Meredith was found slain in Perugia, Italy.

He told how man-eater Knox was like a PREDATOR sizing up her prey.

She RIPPED off his clothes, GRIPPED him fiercely with her powerful hands.

And she BIT him roughly as they had sizzling sex on their first date.

Elis recalled how she boasted of her DRUGS use. He said: "She wasn't the kind of girl you brought home to your mother. I knew she was just after sex."

Knox, her Italian boyfriend Raffaele Sollecito, 23, and her pal Rudy Hermann Guede, 21, have all been held over the killing.

Police believe student Meredith, from Croydon, South London, had refused to join in extreme group sex.

Elis first met Knox, from Seattle, USA, when she visited the bar where he worked in the Italian town.

He said: "You didn't have to romance Amanda. It was clear what we both wanted so I invited her over to mine."

The 22-year-old Albanian texted her to fix a time to meet and Foxy replied: "(Kisses) to you too, muah muah. See you tomorrow. I will visit you after my lessons. Bye handsome."

That night she arrived at his pad, only yards from the house where Meredith's body was found.

The pair shared pizza and a bottle of wine and, as they watched a film, took a bet on the sexuality of the main character.

Elis said: "It was something like, ‘If he's gay I'll give you a massage'. I won so I got a sensual massage but was shocked by her strong hands.

"I kissed her and she kissed me back hard. She also likes to bite. It was nice but not sweet or soft."

The couple were soon tearing each other's clothes off. Elis said: "We cut straight to the chase. First we gave each other oral sex at the same time.

"She was proud of her athletic body. She straddled me and was grasping my back so hard it hurt.

"The second time we were in what the Italians call the sheep position. Next she was on top, watching me like an animal. She wanted to try lots of positions."

A week later they had another tryst at Elis's home but this time he found it a letdown.

"She seemed detached. We only kissed a little bit. She was like a different person," he said.

The last time Elis spoke to Knox was just hours before she was held by cops.

He said: "I called her because I was worried when I heard her housemate had been killed. It never crossed my mind that she could be involved."

Officers in Perugia have been told Knox had a string of lovers — and that Meredith was concerned at the number of men she brought back to the house.

Another suspect, Rudy Guede, has made a bizarre claim about Meredith's final moments.

He now says he tussled with her murderer before running into the bedroom to find her bleeding to death.

She tried to speak to him and whispered the initials AF, which he claims he wrote on the wall as a clue. Police are waiting for him to be extradited from Germany for questioning.

And in another baffling development, cops yesterday said they are hunting for another TWO suspects — a man and a woman — after finding fresh DNA evidence in the bedroom.
