As fantasy fodder, the paid-for-sex fantasy is hard to beat for many women. The money-for-sex scenario offered both tantalizing possibilities and undesirable connotations, however, such as her being a cheap whore. So, I tried recasting the scenario in the least offensive light; for example, she was a high-end ...... or a sexual surrogate. I hit a rich vein of gold with a pillow-talk fantasy I came up with that concerned a rich man we knew who was very much into kinky sex. (The entire story of our interactions with him would make an interesting novella or, even, novel. When you are filthy rich, just about all your desires can be realized.)
The fantasy I created involved him calling us to tell us about a charity drive he was holding that he hoped would yield at least $10,000. I began to point out to him that my wife and I could not afford to give much before he interrupted me by telling me that he didn't seek a cash donation from us, but a different sort of donation altogether. He went on to explain that he was going to hold an auction at his huge house and that three other women had already agreed to offer themselves up for an auction, wherein the winner would get a slave for a day, which included the night and that "sex slave for a day" was closer to the mark. He wanted my wife to be also auctioned. He pointed out that her youth and that she was married made her very desirable to the older men.
In the fantasy, we talked about the situation and she agreed to be auctioned and spend a day with another man as his sex slave. I described to her how the four women each walked out alone, first in a black cocktail dress and they would say their names and give a brief description of their lives, then again each would walk out in lingerie, and, finally, completely naked, which they would remain as they were being auctioned to the highest bidder. I detailed how she made her three trips around the large room filled with rich men. How she looked stellar in her short black dress and expensive nylons and black high heels. How she somewhat revealed her breasts and ass cheeks through the semi-transparent lingerie. How she walked out naked, no shoes, no jewelry, just her entirely exposed body, slowly moving in front of the hungry eyes, making sure to turn around often to better display her ripe rump.
At the end of her naked stroll, she stood atop a small raised platform next the auctioneer, who extolled her lovely features, pointing out how young she was, how her red pubic hair matched the red hair on her head, how suckable her nipples were, and how bitable her ass was. She then lay on her back, with her knees up, her legs open, her pussy on display to the eager men, and the bidding began. The auctioneer acted as if her were displeased with the bids, expecting much larger ones for such a lovely woman, so he had her get on all fours, with her naked ass facing the men. He then described the pleasures of fucking her sweet pussy before the bidding resumed. The highest bidder, her master for a day, won the bid at $3600; and, once his check cleared, she would spend 24 hours with him, doing whatever sexually pleasing him most.
Since my wife often fantasied about being the only one naked in front of strangers, (for example a fire breaks out at night and she rushes out into the street completely naked) I told her how the rich winner had her first do light housework keeping while naked, how he led her into his backyard and sunbathe nude, even though his neighbor's yards held clear views into his. I told her that he took her shopping to buy an expensive and sexy outfit to wear when they went out for dinner that night. In other words, I purposely postponed before introducing actual sex between them. She loved the fantasy so much that I had to repeat it for her during many nights.
Eventually, I came up with a variation she also loved. In it, the rich high-bidder called us a month later, explaining that he enjoyed that night with her so much that he was willing to cut a $10,000 check to the same charity or a charity of our choice, if she joined him on a three-day business trip to Paris. She accepted his offer in the new fantasy and I came up with all sorts of perverse sex scenes for her. I picked Paris, as she spoke fluent French. In another variation, the high bidder won her and another woman, so he could enjoy both at once. Basically, this fantasy lent itself to easy variations. In one, two men had conspired to combine their money to win her, but only one did the bidding. In other words, she got the surprise of having more than one master for a day.
Since in the fantasy she was fucking for money, huge amounts of money, but not money she could keep, the ugly undesirable connotations of being cheap whore never applied.
By the way, I have heard supposedly true stories about young guys being sold at charity auctions and they then having sex with the winning female (or male) master for a day. Remember the scene for the movie, Groundhog Day? I know that high schools and colleges used to have senior auctions, where female students bid on a date with a male senior. But I bet that such slave auctions are now verboten, as we will soon change the names of two months, July and August, as both were named after slave owners.
