They grope Diana

The adventurers are both facing either side of the hallway, backs towards each other while straining at the levers, keeping them down with both hands.

Though nominally without any intelligence of their own, the mage hands spot their opportunity and go to Diana. As she’s busy with the handle, the mage hands float up in front of her chest, and begin working together to start undoing several of the top buttons on her blouse.

For the first few buttons Diana is blissfully unaware, focussed on the lever and the noise from the ascending wall, but by the third button she spots the movement from the corner of her eyes. She stares in confusion, mouth slightly agape, as she watches another blouse button get undone by an unseen ****. Then, with enough buttons opened up to satisfy them, the mage hands rush in towards her cleavage, digging their invisible fingers in between her skin and her bra, and begin fondling and squeezing with the enthusiasm of an adolescent boy.

Diana’s moment of stunned observation turns to shrieking, as she lets go of the lever and begins patting aimlessly across her breasts and in the air, hoping to push off some invisible person (not realizing they’re just disembodied hands). With the lever released, the wall plummets back down.

”Wha’ the-“ Tyra mutters angrily at the wall and her lever, spinning around to see Diana slapping about, ”what’s all this, why’d you let go?!”

“Look!!” Diana stops waving her arms about and - though visibly panicky - stands still. Visibly through her unbuttoned blouse, her boobs continue to get moved and pushed about, the indentations of incorporeal fingers digging in clearly visible.

Tyra gets flustered for a moment.

”Dispel it, whatever it is!” Diana whimpers
