Reppi was relentless.

Once again, she dragged her finger with transparency activated, and revealed just her breasts. It was so sudden that she didn't cover them straight away, giving Vibit a full view. It was an image that would forever stay in his memory. Not did her chest become bare, but they were still squeezed beneath the covering of the dress, even if it was as transparent as air. They squeezed further when she wrapped her arms around herself in panic.

"That's a new style, huh, Vibit?" asked Reppi. "A really bold style. But I wonder what happens if I do this."

She flicked her finger and covered Rosie's breasts back up. Next, she slowly pulled up from the bottom of the dress. Even if the material was still there, even to Vibit, it looked as if her dress was disintegrating from the brim of the skirt and up. Rosie looked in horror as her covering was getting shorter and shorter. Soon, the bottom of her white panties were down, and she covered up with a hand in front and one over her rear.

"Too high!" Rosie shouted, though in an airy whisper. "Stop stop!"

The dress continued to turn invisible up to her naval, leaving the poor girl bottomless. She squirmed. Even with a hand in front, it didn't do all that much. Vibit could see her slender thighs and hips, and if anyone were to look over, they would see an amazing behind.

"You covered up again. That was my hypothesis. But let me test this theory," Reppi said.

Just like earlier, the material around her breasts started disappearing. She was helpless this time. Covering them would mean uncovering her lower-half. She did the only thing she could think to do, which was to wrap an arm over her bust, and keep a hand over her rear. This way, only Vibit and Reppi would see the front of her panties.

"You might not want to do that. Just warning you," Reppi said.

"Why?" Rosie asked, trembling.

"Hm. What's this? A panties switch? Let's see here. Oh yes. I can change the colour of this too."

"No no no."

"Oh yes. Three, two one..."

Rosie panicked and covered up her bottom half again, allowing her breasts to become revealed again. But just after she did that, Reppi flicked, and as she said, the girl's underwear turned invisible too. Now it was only her two hands covering up her ass and tits from someone seeing them, and at that point, someone surely had. Rosie didn't know what to do!

"Ooh. What a conundrum," said Reppi. "What do you cover?

She moved her finger quickly up the entire figure, and Rosie's dressed entirely disappeared. This was hardly even for a single second, however. She flicked again and the dress was back to normal.

With her heart racing, Rosie slowly stopped covering herself, though was on constant guard.

"We'll keep those panties invisible underneath, just in case," Reppi added. "Just for fun."

Rosie laughed awkwardly. "Okay, you really got me this time. I feel so embarrassed. Can I please have the remote now?"

"But the party is just starting!"
