And despite being the fastest man on the planet, Duarte, 20, insisted their bedroom action was more marathon than sprint spanning two hour-long sessions but stopping short of another 'triple'.
Duarte also revealed how Bolt promised to take her out on another date only to make a dash for the airport when their tryst hit the headlines.
'I really thought we had something going, she told Daily Mail Online. 'But now I can see that he picks up women as quickly as he picks up gold medals.'
Duarte was in glitzy club All In, in Rio's upmarket Barra district, when word got around that the track and field superstar had arrived in the early hours of Sunday to celebrate his 30th birthday.
As she partied with friends the runner came close and closer to her group, flaunting his toned athlete's physique to grab their attention.
'He was stood in front of us and suddenly he pulled up his shirt and showed us his six pack,' Duarte went on. 'I had never seen anything like it. I just had to reach out and stroke it.
'It felt incredible. The muscles were as hard as stone. But I was paying so much attention to his abs that at first I didn't even notice it was Usain Bolt.'
Bolt, who has a long-term girlfriend, sang and danced into the early hours having just earned the third of his three Olympic gold medals at Rio 2016.
As the night came to an end he circled back for mother-of-two Duarte and sent his bodyguard over to 'summon' her.
'I knew who he was from TV. My mother has been screaming during all his races because she's such a huge fan,' said Duarte
'He's dark, tall, muscly - just my type - but there were so many beautiful girls there I never imagined I would be the one.
'The bodyguard said Bolt wants you to come over. I didn't go at first because I was playing hard to get. Most girls would go over there like a shot but I wanted to make him work.
'When I was waiting in line to pay at the end of the night he sent the bodyguard over again. He said "why are you not following him? This is Usain Bolt".
'Finally we were waiting in line for a taxi and he smiled at me and did the famous victory pose so I was in no doubt who he was.
'That's was when I decided it was time to give in to him. He pulled me into the taxi and gave me an incredible kiss.'
Duarte said the pair made their way back to the official Rio 2016 Athletes' Village where security was supposed to be strictly controlled with non-competitors barred from entry after 9pm.
But the pair bypassed security by hopping on to an official bus that was quickly waved through the gates.
'They never asked me for any sort of pass or my ID,' said the young Brazilian beauty.
'They didn't even question him, I guess, because he's Bolt. We had two other guys with us and I think they were athletes because they also had muscly, fit bodies.
'I was surprised that he didn't take me to an expensive hotel but I didn't pay much attention because we were kissing the entire way.
They both undressed and showered before Bolt played his favorite music on his phone.
'It was mainly just small talk and him telling me how beautiful I was,' she said. 'We used Google but I didn't need a translator to tell me that he wanted sex.
'He played the Rihanna song Work. I think he likes to listen to it when he makes love.
'It was very passionate and hot - we were devouring one another. He has the body of a champion although his male parts do not match - he is just like a regular guy.
'I was expecting him to be fast but it was actually the slowest sex I've ever had. We did it for about 40 minutes then he took a couple of minutes rest before we did it again.
'He was certainly quick at recovering but we didn't have sex a third time.'
Duarte says the two lovers took selfies, hung out in bed and listened to music until 9am, when Bolt handed her a 100 Euro note to get a taxi.
Bolt didn't give her his number but promised to call her to arrange a second date during the Paralympics, which starts September 7.
