Of about 20 women who work at the Kit Kat Ranch, one of Nevada’s legal brothels, Katherine Stone is the only virgin.

She has been living there since May, learning the ropes and entertaining “clients” – but not for sex. Stone is auctioning off her virginity to the highest bidder, saying she wants to save herself for someone special.

Bids for her virginity are reportedly at $400,000, she said.

The unusual arrangement was set up so that Stone, 21, who grew up wanting to become a lawyer, could raise money to help her family, she said.

In December 2014, an electrical fire destroyed her family’s Seattle home and its contents.

Last summer, she said she came across the story of Natalie Dylan, a woman who reportedly tried to auction her virginity in 2008 to pay for college. Dylan had orchestrated the online auction through Dennis Hof, a Nevada businessman who owns seven brothels in the state.

So Stone looked up Hof, found his email address and sent him a note.

Nevada is the only state in the country in which prostitution is legal, though brothels are only allowed in certain counties.

Hof is fond of saying he owns “40 percent” of those brothels.

Stone is not the first woman to try to auction off her virginity. Most recently, a college student in Russia reportedly put her virginity up for auction on an escort site to raise tuition money, according to the Daily Mail. There is no timeline on the auction, and Stone is still waiting for more bids to come in.

“$400,000 is just the start,” she said. “It’s still early in the process. I’m still learning a lot of stuff here at the brothel. It’s still too soon to even decide.”
