She takes Mackenzie to the photo booth.

"Boy, what to do, what to do?" wondered Rosalyn aloud as she pulled her pants back on. "Tell you what." She grabbed Mackenzie's hand, which made her squeak because it involved pulling it away from covering her crotch. "I want something to remember this moment by. Come on."

Mackenzie stumbled as Rosalyn half-led, half-dragged her along, keeping her head bowed in shame as they passed through the amused crowd. Looking up, she saw where Rosalyn was taking her, and dread filled the pit of her stomach.

"Go on." Rosalyn pulled back the curtain on the photo booth and pointed inside. "Get in."

Briefly Mackenzie considered trying to make a run for it, but she had seen how fast Rosalyn's reflexes were. Hell, it was the reason she was naked right now. Rosalyn would probably just tackle her, and then think of a way to make her humiliation even worse. Reluctantly, Mackenzie stepped into the photo booth. Why did I make this bet in the first place? Now she's going to have pictures of me naked!

Rosalyn came in after her, closing the curtain behind them. She hummed to herself as she flicked through the theme options on the touchscreen, then grinned and selected "Romantic." Immediately the screen filled up with pink hearts and ribbons, and Rosalyn turned her attention back to Mackenzie. "Come on, honey!" She wrapped an arm around Mackenzie's bare body in a partner-like fashion, making her flinch again. "Smile!"

Several minutes later, they emerged from the photo booth - Rosalyn beaming with pleasure, and Mackenzie crimson-faced and shaking with embarrassment. From a slot on the side of the booth came sliding several glossy photographs, and Rosalyn held them up so Mackenzie could get a good look at them. "You look so cute in these!"

The first one was of the nude Mackenzie and the fully dressed Rosalyn, with Rosalyn wrapping a companionable arm around her unfortunate victim and leaning a head on her bare shoulder. Rosalyn had a beauteous smile on her face, while Mackenzie had her eyes screwed shut and her arms clasped over her breasts. In the second one, Rosalyn was planting an intimate kiss on Mackenzie's cheek, while Mackenzie stood there with her arms at her sides. (Rosalyn had insisted that she no longer be allowed to cover herself.) In the next one, Rosalyn had made Mackenzie raise her arms above her head, making her breasts thrust out prominently, and give a smile that would have been fairly convincing if it weren't for her beet-red face.

Another one featured Mackenzie with her back to the camera, both hands grasping her own exposed buttocks, while Rosalyn pointed to her bottom with an exaggerated look of shock on her face. In another, Rosalyn had made Mackenzie kiss her on the cheek, while she smirked with satisfaction at the camera. In another, Rosalyn was behind Mackenzie, using her hands to cover Mackenzie's breasts and crotch - which Mackenzie had found somehow more humiliating than having them uncovered altogether.

It went on like that. Rosalyn had had a lot of ideas for ways to pose Mackenzie, each feeling more humiliating than the last. Now she seemed at least triumphant and satisfied, having thoroughly established her dominance over the other girl. "These," she said, waving the wad of photographs for emphasis. "are all solid gold. Never going to let go of these. Might have to post 'em all up on Facebook. Maybe I'll tag you in them!"

The idea made Mackenzie gasp. "You can't do that! I'd...I'd be..."

"What, humiliated? I think that ship already sailed, sweetie."

Mackenzie stared at her with a mixture of terror and abject loathing. "Just...just give me back my clothes already. You won."
