Charity Auction Steve/Tony Fic
I can't remember if it was one chapter or just a one shot but it involved Steve not realizing that he was signed up for a person auction. The hostess was nasty and Pepper is going to ruin her. Tony ends up bidding. Hostess gets offended and says its only for woman but Steve says anyone should be able to bid. Reporters are all over them after the auction. Natasha was supposed to bid first.
