"You know I wouldn't ask if there was any other way," Victoria gasped, clutching her bouquet to her chest as she struggled not to hyperventilate. Her face, green with dread, stood out against her bone-white wedding dress.
"Don't sweat it," Marcus grinned, stepping between the autocloset's steel doors. "He needs a bride more than a best man, right? He'll barely notice me missing."
"It's just the thought of being up there in front of everybody... All those people... watching..." Victoria wretched. Just the thought of being exposed to public scrutiny like that was giving her palpitations. The dress that had looked so beautiful in the store now felt utterly revealing, as if every mole or blemish was on display for her friends and family to judge. And she'd spent so long agonizing over it, all that effort now wasted.
She removed her white veil and dropped it forlornly into the hopper on the side of the autocloset. She did the same with her garter belt. With a sigh of sadness mixed with relief, she unclipped the clasps of the dress, the white satin rippling down her body to pool on the floor.
Not be caught ogling his best friend's fiancé, Marcus politely turned away from the body he'd soon possess. "Pour a glass of champagne and put your feet up, I got this," he winked. "Oh, and you'd best set the closet to high speed. I'll feel like a smoothie in a blender, but we've only got forty minutes before he walks his blushing bride down the aisle."
"R-right," she stammered, twisting a dial to its maximum setting.
The autocloset doors slammed shut behind him.
The machine wasted no time. A whir of blades faster than he could see turned his skin to confetti, a thousand microneedles prickling his flesh as a million microdosages of silicone gel plumped out his exposed male muscles, which were being cut, stretched out and resutured on the bones. The tendons and ligaments around his hips were analyzed by advanced AI protocols and restrung so that, when he walked down that aisle, his pelvis would be forced into the perfect feminine sway.
A panel opened and mechanical arms lifted a wrinkled, sagging sleeve formed of fresh pink synthskin into the chamber.
   As it was dragged up over his thick, flayed ass, the sagging wrinkles stretched out like filling pumped into sausage skin, smoothing into the curvaceous form of the bride-to-be. He cupped his breasts, a perfect replica of Victoria's own, admiring his pretty face in the polished metal walls. The freshness of the synthskin gave it the blushing glow of a woman on the happiest day of her life.
A hose rinsed away every droplet of gore before the machine risked bringing the pure white clothes into the sealed chamber, its mechanical arms tugging and teasing them gently about his altered body. Delicate satin panties were drawn up between his legs to nestle against his smooth crotch, a garter belt snapping into place around one supple thigh.
A metal headset was placed upon his blonde head.
"You guys got the neural synchroniser installed. Nice."
Her voice called through the metal wall. "We spent months planning this so you'll need to learn the vows. Okay, we're joined. Focus on my memories of planning the wedding."
A tangle of memories touched on his awareness, distorted by her current anxious state and the electronic wires they were being zapped down. Months of dry meetings with venue owners, chosing the perfect shade of flowers, agonising over which family members to invite and which to ostracise forever. Vows... Vows... they had to be in here somewhere... He fumbled blindly through her memories. How hard could it be to find 'I love you'?
A vivid image flashed before his eyes - lying on his back, legs spread, moaning 'I love you' as his best friend plowed into him. Another of him on his knees, pleasuring him with his mouth. Is he really so big? A query that naturally forced a slew of corrobating memories into his mind. So much for saving themselves for marriage. Machine arms held him aloft as his legs trembled, and the autocloset echoed with his high, feminine groans of pleasure as a slideshow of their every intimate interaction zapped through his brain.
The Autocloset doors opened. He blinked through the haze of a thousand remembered orgasms.
"Did you get the vows?" Victoria asked.
"His it been forty minutes already?" he murmured. He wiped the drool off his chin and smiled. "Eh. I'll wing it."
