About a week after Anna's birthday, she and Tracey got a text message inviting them to an adults-only Halloween party, hosted by a well-to-do young couple who loved to throw parties known for their wildness. It would be a costume party, naturally, and a lot of people, most of whom found parties the wilder the better, were expected to be there. In fact, prior to the pandemic, this party had quite a reputation as being one of the hottest Halloween parties around; getting an invitation was quite a feather in one's social cap and carried lots of bragging rights. Halloween parties hadn't ceased during the pandemic, had rather just become "secret," but this year's event would be the first full-blown, let-it-all-hang-out shindig in a while. That Anna and Tracey would attend was a no-brainer; what they would go as was more problematic.
"How about if I go as Little Bo Peep," Anna suggested, "and you go as one of my sheep."
"Ha-ha, very funny," replied Tracey. "If you go as Little Bo Peep I'll be that big staff she's always carrying and poke you up your ass all night."
"You would love that, I'm sure."
"Almost as much as you would." This kind of back-and-forth bantering was typical for them; they actually loved each other very much.
They bounced a few other ideas around, some even more ridiculous than that one, and even thought about scuttling the idea of going in tandem, but then thought of something they had been in the past: a mistress-slave twosome.
"Yeah, that was fun," remembered Tracey. "Even when you thought I was going to dump you for Ellie Colfax after you imagined you saw us hitting on each other."
"Well," replied Anna, "we'd only been together a few months, so I guess I was still not very confident yet about us. Silly me. But I don't think I was imagining anything about you and Ellie. You two looked ready to pounce."
"Silly, indeed," stated Tracey. "Maybe I was tempted, but all I had to do was think of us for a minute, and I knew Ellie would have to go on the shelf, at least for a while. Us first, and then we could decide where Ellie might fit in. I wonder whatever happened to Ellie?"
"I heard she married some guy and they have three kids now and live out West somewhere."
"Really?"
Anna chuckled. "No, I don't know what happened to her. I just made that up in case you were going to start mooning over her again."
"Somehow I just can't imagine her craving the same things we do, so I doubt there'd be much mooning." What she was referring to was something they discovered about each other at about that same time, that they both had a deep, all-consuming compulsion for the scat fetish. The love for it defined them sexually, and soon after making that discovery they became inseparable lovers.
"If we agree on this theme for the party, I want to be the slave," insisted Tracey. "You were the slave for your birthday, so now it's my turn."
"But I was so good in that role, and you've got to admit, everything unfolded perfectly. That was one hot scat session we had."
"Yeah, I know," replied Tracey. "But I can perform that role just as well, and like I said, it's my turn."
They yammered back and forth for a few more minutes about this before Anna relented. "Okay, okay. I'll be the mistress."
The party wouldn't be for a couple of weeks, so they had time to plan things meticulously, much more so than the last time they'd assumed these roles. It would still be pretty warm, so they could wear skimpy costumes and not worry about freezing, even if it meant at some point they might not be wearing any costumes at all. They knew many of the people who would be attending, and figured anything might happen, especially after everyone was drunk or high. If it turned into an orgy, it would be no surprise.
First they thought about what they would wear. They figured that other couples, mainly guy-girl couples, or even larger groups of people, would come as either the same thing or something similar, and wanted to stand out from them. No stereotypical store-bought costumes, they decided, they would use what they already had in their wardrobes. Anna would wear a tight black miniskirt with thigh-high black stockings and stilettos, no underwear, and a plunging neckline silk blouse that exposed her midsection; Tracey a bikini thong and a see-through camisole with thigh-high boots, nothing else, except for a leather dog collar with a leash attached that Anna would lead her around by. Both would also don similar lacy black Venetian party masks that covered their eyes. They figured that others would be there in sexy outfits, but hopefully not quite like theirs.
