"Hey guys!" Julianne called out as her co-workers arrived.  "Guess what showed up today?"

"Your internet boyfriend from Canada?" Felicity snarked back.  She took off her coat, shaking off the worst of the winter snow before setting it out where it could dry off.

"No," Julianne shook her head.  "You know that guy who does those 3D models of tricks I was talking too?"

"Yeah," this time the answer came from the third member of the group, Lohan.  "What, you finally convinced him to part with a design?"

"Not exactly," Julianne replied.  "He actually sent us one to test out and give feedback on!"

"What?"  "Really?"

"Yeah!" Julianne confirmed.  "It's over here!"

Lohan kicked off her boots. "Cool!  Let's see it!"

The two followed Julianne to a crate that was about chest high, and roughly square on the base.  "It's a crate," Felicity stated the obvious.  "Made of wood."

"Well, it's from him," Julianne confirmed.  "I got a letter and everything!"

"I believe you," Felicity said. "I'm just surprised you hadn't opened it up already."

Any answer was prevented by Lohan slipping a crowbar under the lid, and prying it open.  The nails groaned as they were pulled out, and without another word the other two joined her in extracting the performance piece from its shipping container.

Lohan was the first to react. "Huh."

"The letter says it's an erotic illusion," Julianne read out. "The assistant kneels in the box, and gets cut up."

The 'box' was a chest high thing, grey on the outside and with a blue interior that was easily visible from the transparent front.  Looking at it from the front, on the right was some sort of handles, attached to the stocks inside the top section of the box.  Below that was an inset handle for a blue sliding box that easily slid in and out.  Then there were two cuts in the box.  On the left side, there was another handle, then two cuts that lines up with the top and bottom of the sliding portion, then another inset blue handle to that also operated a sliding section that matched up with the cuts on the right.

"It's a thing." Felicity knelt down.  "Did he say how it works?"

"The assistant kneels in the box, is locked in place, and mis-made." Julianne read aloud.  "He included a picture."  She pulled it out and showed it to the others.

"Uh, she has hands through holes that aren't there." Lohan said as she tapped the box.  "In fact, there is no front at all. Did he forget them after the 3D model got printed?"

"No," Julianne kept reading. "He says that they will be in the final product, and to make due for now."

"So, who wants to go first?" Felicity asked.

"Not me!" Julianne said.

"Not it!" Lohan added.

Felicity sighed.  "Fine.  What's the first step?"

"Get Naked!" Julianne cried out.  "It's supposed to be an erotic performance, and the 3D picture he gave us clearly shows a naked assistant!"

Felicity shook her head, but didn't fight it.  She stripped out of her clothes, handing them over the Lohan, who put them aside.  "So, I kneel in there, facing front, right?"

Julianne nodded.

Felicity turned around and knelt down to back in.  Therein, she encountered her first problem.  "There's not enough room," she said as her feet touched the back of the box.  "If I have to fit like that picture, I have to stand on my knees and fold my legs up behind me."

"Do it," Julianne said. "We're giving feedback, and that's something."

"And if you do that," Lohan said as she came up with several cutting blades, "your feet will be in the same box as your ass, and you know how some people like that."  She didn't name names.

"Fair enough." Felicity agreed and proceeded to do just that. "It's uncomfortable. Needs padding for the knees."

Julianne looked up at her. "Pun intended?"

"Pun Intended," was the confirmation as Felicity slotted her neck into the stock to hold her in place.  "Now what?"

"Well, we close things up," Julianne said, "except we can't do that. So we skip to the cutting part."  She nodded at Lohan, who examined the blades one more time.

"Raise your hands," Lohan said. Felicity complied by mimicking the stance in the picture. Her right hand was held at her waist, while her left was elevated to her breasts.  "Low slot first," Lohan gave warning and slid the metal blade into the lowest section on the right side of the box. Felicity was unable to look down but Julianne watched as the blade passed through her co-workers upper and lower legs at the same time due to how she was sitting.

"That's more comfortable," Felicity said after the first blade went in. "Now I'm resting on my legs, and the weight is off my knees."

"Noted," Julianne said as Lohan lined up the next one.  "Hold on, I'm going to get a mirror."

"I was about to say..." Lohan said, and waited while Julianne got the reflective surface so Felicity could watch as well.  "Ready?"

"Yep!"

This time Lohan pushed the blade through the hip slot.  "Ooh," Felicity twitched. "This is feeling nice."

"Well we're not done," Julianne said.  She walked around to the left side of the box and examined the handle.  "I just pull this and...!"

The blue sub-section slid neatly out of place, stopping before coming completely free of the grey case.  "Nice!" Lohan said from her side.  "How do you feel?"

"Vulnerable," Felicity replied.  "I could feel the move, but without the mirror, it seemed more than it actually was. And without something in the box, anyone could just come up and take advantage of me."

"That's neat," Julianne said, "but maybe later I'll call your boyfriend."

"As nice as that is," Lohan said as she walked around to the left side of the box, "We still have more to go."

Julianne returned to the front of the box. "Right. Time to say good by to your tits!"

"But I just got them!" Felicity replied as Lohan slid in the first blade under her mounds. She drew in a breath at the cold touch. With her right hand, she felt the underside of the blade just as her left touched the top. "Not bad."

"And the last one!" Lohan said before pushing the last blade through Felicity above her breasts.  "And done!"  She walked back to the other side and pulled on the sliding box containing the recently severed chest, giving Julianne a nice view as they bounced in the move.

"How do you feel?" Julianne asked as she took in the multi-part Felicity.  The upper chest, neck and head were all in one place, held by the stocks.  The breasts and left arm were to the box's left, hanging on by the barest amount.  The flat stomach was still centred with the right hand while her hips and hidden feet were to the right, leaving her folded legs at the bottom.

"Like I'm going this way and that?" Felicity's usual attitude returned. "It's not bad.  Just needs, you know, a front. And some padding."

"I think," Lohan said as she circled the prop, "that this is best performed with two assistants on the outside."

"What to do you mean?" Julianne prompted her.

"Well, it's too long going back and forth," the other woman said.  "Imagine this: There are four blades, two on each side, and the sliding boxes are out of the cabinet.  The assistant takes her position, and the two on the outside slide in the blades first, then the boxes between them from each side."  She gestured as she talked, indicating how it would be done.  "Then each assistant pulls on their box at the same time, zigging and zagging the woman on the inside."

"I like that," Felicity added in.  "Makes it faster, and multiple pulls could make the woman in here feel it more intensely."

"So, Legs, Knees, and alternate performance method." Julianne ticked off the three major points of feedback she would give the creator.  "Anything else?  Oh right!  Pictures!"  She produced her phone and took a couple pictures of Felicity in the trick. "There, proof to send him."

After waiting out of frame, Lohan stepped back up. "I want to go next."

"Fine by me," Felicity agreed. "Put me back together and we can practice your version."

"On it," Lohan agreed and started to restore Felicity.  "You going to get dressed first?"

"Nah," Felicity said as she was slid back into place. "I think I'll take your suggestion and call my boyfriend when we're done here.  Let him have some fun."

"We'll clear out before then," Julianne promised.  "Now, Lohan's turn!"
