Their own telepathy

They had to clear out the room outside; none of them needed to even say that aloud. However they were meant to deal with their exposed state, they couldn't if there were countless people poised to see them.

And those mutants would only leave after hearing what the Frost Sisters had to say, and they couldn't say anything without going out there.

"We might be able to trick them," Esme said. "We can still influence their minds."

"Make them see something that isn't there, like-"

"Clothes," Sophie said. "But only one one of us. That's a lot of people to-"

"Convince, I know, but only one of us needs to talk, two can focus on-"

"Tricking their minds to see clothes," Phoebe said.

The nude sisters huddled together, still feeling nervous. It might work as a plan, but it would still mean walking out of the room stark naked.

As though they had any option. If they tried to wait it out, chances were someone outside would worry something had gone wrong and burst in; they had to avoid that. Esme flushed just thinking of it and, as ever, her blush was mirrored.

And they had to be subtle. They couldn't be caught manipulating the minds of their new recruits right away, not if they wanted to earn their trust. That meant nothing overt like compelling them all to just leave.

But something that wasn't notable, something like a false impression of what they saw... That was doable.

"Esme," Sophie and Phoebe said in unison.

"Why me?" Esme said; her cheeks burned.

"It has to be one of us, and you-"

"Weren't at Trask. This balances things."

She faltered. Fuck; but then, she was outnumbered. Reluctantly Esme nodded, moving away from her sisters and nervously approaching the door.

She tried to stand naturally, facing the door and feeling the air almost seem to fizz against all her exposed skin. To her sides, her sisters stayed out of view of the doorway, but their eyes shone blue.

They didn't need to nod; she felt when they were using their power. This was probably the best chance they'd get.

Esme swallowed, then opened the door. She walked out, seeing the mutants turn, feeling their eyes on her naked body, mentally praying her sisters could keep the persuasion up.
