Lisa smiled as Matt rang the bell. Mansion was the word that sprang to mind , but in truth most people who could afford her more personal services tended to live somewhere pretty upscale. Matt's suv looked rather lost on the long drive. Lisa almost expected the door to be opened by an English butler from an old movie. Instead it was a younger guy than she had been expecting, good looking, 30 at most.

"Matt? And you must be the assistant? Please come in..." 

Lisa smiled to herself. No point being offended, she was used to being a commodity at least part of the time. She followed Matt along a long hallway to some sort of garden room, as big as many a small house, glass doors at one end opened onto extensive grounds. In the far corner biting her nails nervously was who Lisa took to be the lady of the house. Probably even younger a conservative floral dress accented her Hispanic olive complexion and  hid a promising figure. She was very attractive.

"This is Cali, my fiance.." 

"How can we help? " 

"We have a problem you might be able to solve for us"  The young woman's voice was more confident than her manner suggested Lisa thought. 

"OK try us..."  

"Tristan ? " 

"Well, its . Its not easy to .."

"Nothing you say will shock us, trust me. Just explain what you want, or if you don't know what you want, what you are trying to get to and we will do our best to make your dream come true.." Lisa purred.

Tristan cleared his throat. "Well here is the truth of it. We are due to get married in the fall."

"Congratulations.." 

"Thank you. We can't wait. And in a way, that's the heart of the problem. Cali is a virgin and wants to wait. I am not a virgin, and i'm struggling waiting any longer ....."

Cali chimed in. "We get naked, fool around, but that's not enough any longer. I am not a prude, I just want the first time to be on my wedding night. "

Matt took a deep breath. "OK will how do you think we can help? Although our services often have a sexual content we aren't an escort service, there are plenty of those ? " 

Cali looked at her shoes for a second then cleared her throat. " Well, there's no easy way.. He needs sex, he can't wait any longer, I want to wait, so he has suggested one of your magical effects so that we get to have sex without my parts actually having sex, as such..."

"So you just want to do a body swap?" Lisa asked calmly.

"I figured if we were going to all this effort we could try something more adventurous?" Tristan mumbled.

"And I figured if we , well I, was in the throes of some odd magical kink of his it will be less like he's sleeping with someone else ..." 

"Makes sense" Lisa smiled, even though she was thinking more or less the exact opposite. 

"Ok, let me have a think.... I have a sort of idea .... Cali you will need to get changed, just a robe will do nicely.... just give me a minute....."

Matt wandered over to the french doors and looked out to the extensive grounds for a few minutes. Cali looked a bit startled at such a direct opening to the proceedings but hurried off. She was only gone a couple of minutes returning wearing a fluffy white robe and looking more than a little self conscious. 

"OK so I think I have a plan ... as I understand it you don't want to know Cali? "

"No, no thank you. I will just go with the flow and see what happens I guess. I think that's best."

"In that case, would you like to follow me outside ? Lisa..." 

Lisa nodded and kicked off her heels, then undone the bow on the front of her conservative summer dress. She shrugged and with practiced ease slid out of the dress revealing her to be quite naked beneath. Matt has assembled her with a more conservative natural figure, slender with curves in the right places but not too exagerated,  which made a nice change. She actually might have some of her own parts. Lisa followed the others out onto the huge deck area. She grinned at the open jawed expressions on their new clients faces. At the far end of the deck nearest the lawn was a magic box. It looked for all the world like a standard sort of interlude illusion. A slender pyramid shaped box with the point missing, topped with a t piece. Matt beckoned Cali closer. 

"OK Cali we need to get you into here. I'm afraid the robe will be in the way...."

Cali took the robe off hesitantly, folding it neatly and leaving it on a nearby lounger. Lisa had been right she was beautiful. Under Matt's soothing ministrations Cali backed herself into the box, looking more and more nervous. 

"Thank you baby, you know this means so much to me..."

"I sure hope so.... "

Matt added a front panel to the strange box, covering Cali from neck to the top of her thighs. Then he secured her wrists to the cross bar with ribbon like ties. He spun the little box around on its wheeled platform, as if there was a real audience. 

"I think I recgnise this.." Cali mumbled.." Not sure how its going to help.

By way of response Matt directed Lisa to the back of the box. On his mark she reached into the black fabric panel covering Cali's back. Her arm sunk in. Cali cried out. It was hard to tell if it was due to pleasure or pain, the cry trailing into a soft moan. Lisa reached in further. Her arm sunk up to the shoulder and her hand popped out through the front panel.

"Oh my.. that's intense. I have never felt anything ...ohhh OH."

Lisa smiled knowingly and wriggled her arm round as much as she could. She knew exactly why Cali had never felt anything like it. Once Cali had calmed a little Lisa reached in with the other hand, shuffling closer, prompting more moans. Cali looked down in wonder. 

"But this is just a trick, but but I am still here. I mean ..."she gasped and took a couple of very deep breaths "... and how does this help Tris with his...problem?"

Lisa chose this moment to shove her head and shoulders right through the box, and by implication, Cali. There was another low moan. She writhed as seductively as she could, catching Tristan's eye. he looked tense. 

"OK Lisa I want you to pull your left arm in a bit then reach down. You may have to push..." 

"What, wait!" Cali's protests were cut short by an indescribable wave of sensations as she felt something explode through her hips . It felt to all the world like something was pushing down inside her leg... "Oh shi....."

Lisa waited for a few seconds then wriggled about a bit and pulled her other arm in and thrust downwards. 

"I still don't understand..." Tristan objected, apparently slightly annoyed that his wife to be may be enjoying things more than he was so far. Lisa wasn't sure how this was going to meet the brief either if she was honest. 

"Now the tricky bit.." Still not troubling anyone with a hint of explanation Matt walked to the back of the box and grabbed Lisa's rear end pushing her in to the mysterious box a little deeper, her till her breasts had slipped into the back of the box. Spinning the the box around he smiled then grasped Lisa's protruding head by the ears. He twisted one way then the other before pressing down and in a little at the same time lifting Lisa's chin. Each move elicited another series of moans from Cali, who was clenching her fists too. When Lisa's head was at the very base of the box he pushed her head back in. Tristan looked at the results puzzled. His fiancee is the box with Lisa's ribcage back sticking out the back. In one smooth movement Matt pulled away both the front and back of the box. He freed Cali's wrists and had her step forwards. 

Tristan could not believe his eyes. Cali had somehow assumed the form of a animal, a horse perhaps. A second back, butt and pair of legs sprung from her back, like some mythical beast. When Matt took Cali by the hand and had her turn towards her husband to be Tristan almost passed out. He sat on a lounger with a thud.

"What? what  ? " Cali sounded a little frightened. 

Tristan looked again. There was no mistake. Where his fiancees legs met, where her pussy should begin, was instead what was unmistakably Lisa's smiling face. Matt had Cali look at her much modified reflection in the glass doors. 

"So you see Tristan has three holes for his enjoyment...." Matt tapped Lisa on the lips, then pussy and ass, totally unnecessarily.." which do not belong to Cali ...which  Tristan can use as he wishes, where as Cali has two holes less than usual, thereby removing any temptation. Lisa there is just along for ride, only Cali can control all the limbs, even the extra ones. Lisa can still see hear and suck, but I have removed her voice , three being a crowd and all....."

Lisa pouted, then smiled and licked her lips suggestively, willing Cali to wiggle her old hips. 

"Now I will leave you to get used to things, and will be back next week to restore you... Have fun.. "

And with that he was gone.
