Catarina Migliorini's virginity auction was organized by Virgins Wanted, the project of Australian filmmaker Justin Sisely.
Both Migliorini and a young male virgin, Alexander Stepanov, hocked their virginity online. Stepanov's first time went to a buy identified as Nene B. from Brazil for a mere $3,000 US.
The auction had been live since Sept. 17, but until Wednesday - the last day of bidding - the highest bid for Migliorini had been $150,000. Natsu beat out five other high rollers who all bid in excess of $600,000 for the chance to bed the virgin.
Under the rules of the auction, Migliorini will be examined by a gynecologist and will "provide the winning bidder with medical evidence of her virginity." Stepanov's virginity cannot be medically proven, so he and two of his family members will give "statutory declarations to support his claim."
Speaking last month with the Folha de S. Paulo newspaper, Migliorini said she got involved with the project two years ago when she saw a story about an Australian filmmaker who was looking for a virgin. She claims she wants to open an NGO with her winnings and invest in a public-housing project for poor families in Santa Catarina, where she was born. But speaking with the Huffington Post recently, Sisely said he was skeptical of Migliorini's purported good intentions.
"I was surprised she said that because in all my dealings with her, she made it clear that it was a business decision for her," he said. "Now, given how big this story is in Brazil, she's trapped. If she doesn't give any money to charity, she's going to look bad."
The winning bidders must submit to a medical examination and a police check, and cannot be intoxicated during their time with the virgins. No kissing or fellatio is allowed, and although the virgins and the winners are to agree about the length and duration of the sex, "the minimum consummation time is one hour," the rules state.
Migliorini, who said she doesn't think of it as prostitution, said the sex will happen in a private airplane.
The Virgins Wanted website said only that "the sexual act will take place where it is not illegal."
