Football agent Pedro Campane said: "She was like a wild animal in bed.
"We slept together the first night we met. It wasn't difficult persuading her.
"She didn't have any hang-ups. She liked doing everything in every position.
"Nereida Gallardo doesn't know much about football but she knows lots about men—and how to please them. Cristiano must be having a mind-blowing time."
Pedro recalled how he bedded Nereida in his penthouse just hours after they first met in her native Majorca at the end of May 2006.
He said: "I was introduced to her at a party and we became more than friends straight away.
"She was 22, very hot, and I wasn't going to waste any time. Conquering her was very easy. She liked partying and money and I could give her both.
"I'm very well-known on the island. I get invited to lots of VIP parties at nightclubs like Tito's and Eventos.
"From the very start Nereida wanted to go to them with me because we were always well looked after and she loves being in the spotlight.
"And I was interested because she was very sexy - even more so than she is now.
"And she was never shy. She loved people seeing her naked. It gave her a thrill.
"One day she wanted me to buy her lingerie but I said I wanted to be there while she tried it on.
"She didn't bat an eyelid. She really got off on giving me a show.
"There were other people watching in the boutique too but it didn't bother her at all.
"She stripped off without a second thought.
"She didn't even bother closing the changing room curtain. She knows she has a sexy body and didn't care who she showed."
But Pedro revealed how his affair with Nereida fizzled out because he grew bored with all the sex.
"It's very nice being with a beautiful girl who you can sleep with whenever you want.
"But there comes a time when you get tired of something just based on sex and money and you move on. That's what happened to me."
After the pair split, Nereida moved on and dated a string of four Spanish soccer players, as well as a singer and several businessmen.
Pedro added: "She doesn't hang about and who can blame her? She's got looks on her side and she's a girl in a hurry."
