Crossdressing

Ashley looks at you and you catch a sudden glint in her eye.
"I know," she says "Let's dress him up as a pretty little girl and fuck him. I'll bet he's picked up tons of sluts at bars, and loves to fuck them mercilessly. So now, it's his turn to play the girl."
The "girls" around you giggle, with malice.
"I'll go get my costumes!" Ashley says with nauseating glee. She walks over to the closet, opens the door and starts rummaging through the contents, tossing several outfits onto the floor.
Susan climbs up the bed and puts her lips to your ear.
"Hear that, your going to dress up as the little sissy bitch you are."
You can feel her erection through her pants. As she climbs off you, you can see a wide assortment of garments go flying out of the closet. Ashley is obviously searching for something specific.
After a few moments, you hear a triumphant: "Aha!"
Ashley emerges from the closet, brandishing a two piece cheerleading outfit, not unlike her own. The only differences are that the red and orange have been switched for pink and white and the letters S.L.U.T. are displayed across the chest. There are also pink socks with white rings, and pom poms to go with it.
"What do you think?" She asks optimistically.
The others seem less impressed with her selection. Brianna sighs, "Of all the costumes in your collection, that is what you chose!?"
"What's wrong with it?" Ashley protests. "I like it."
"You've got so many humiliating ones, I was hoping for something really cruel. Can't you find a few others first?"
Ashley turns to the pile of outfits on the floor and grumbles as she roots through it. Finally she removes two other costumes from the pile and lay them out on the bed.
The first is a pink princess gown with a gold tiara. It looks like a cheap prop from a highschool play, and you cringe at the thought of wearing it.
The final choice is a full body, skin tight, black velvet cat costume. It comes with a mask, ears and a tail. You can see that the outfit is crotchless. Suddenly the pink dress doesn't sound so horrible.
Ashley looks as her selections and turns to the group.
"Happy now?" She asks Brianna with more than a hint of annoyance in her voice.
"Yes, quite. Alright, we'll take a vote."
Which costume will they choose?
