ASEC - Pre-Flight

Captain Jenkins was more than proud of his flight deck and cabin crew - he held them up as the best his airline Speedair had to offer. They ran one of the daily commuter flights between Edinburgh and London on weekdays, and everyone knew that Jenkins was a fair but firm man with a focus on preparation.

Jim Jenkins and his first officer Paul Garrett met in the airline flight briefing office ninety minutes prior to departure to review weather, routing and any issues at departure, arrival and diversion airports. They then picked up their cabin crew - Linsey, Gemma, Danielle, Chris and Frank - from the staff room, and headed out to the aircraft. But in the corridor between the security checkpoint and the apron, they were met by a woman in the uniform of Highland Air... or rather a woman who was barely contained by her uniform.

She looked like something from a porn film. Though her jacket was buttoned, it was straining against the creamy breasts that had clearly popped the buttons on the blouse and were overflowing the lacy cups of her bra. Her hips and ass were pronounced, and were taxing her skirt in a similar way. Pouting, sexy lips and pale sea-blue eyes dominated her face. She marched up to the captain and put her hand on his crotch. "Come on Captain Jim," she breathed, "take me to your office and fuck me. You're so tall and manly, I bet you've got a huge dick."

Calmly and gently, Jim put his hands on the woman's shoulders and pushed her off. "Have you been drinking, Miss?" She giggled and moved onto Paul, stroking his chest. Jim, eager to avoid distractions but always with an eye on safety, took control. "Garrett, will you escort her back to security? She shouldn't be airside in her condition. We'll see you onboard in a while."

"Come on miss," said Paul, "let's get you somewhere comfortable." As the rest of the crew headed out to the aircraft, Paul led the woman back to the security checkpoint. "What's your name?"

"It's me, Nancy! You've known me for years." Her hand strayed to Paul's well toned biceps. "Oooh, I've always had a thing for you Paul." The only Nancy that Paul could bring to mind at Highland Air was a veteran in her fifties. This woman couldn't have been over twenty five. Her hands were roaming all over him. She stopped him from walking, stood on her tiptoes and kissed him. "Come down the corridor there and let me suck your cock." Paul was a good guy, but he was still a guy. The two scurried down the corridor into an empty office. 

Nancy got onto her knees and let out a yelp of delight as Paul let his hard dick spring free and slap her in the face. He was fairly big, and Nancy had to use both hands to jerk him into her face. Soon she was sucking his balls, feasting on the tip of his dick, and forcing his whole length into her throat. Though he couldn't help glancing around nervously at first - Paul didn't normally do this kind of thing - he was soon relishing the attention Nancy was paying to his pleasure. Before long he was pushing her down onto the carpeted floor, squeezing her big tits around his cock and fucking her cleavage until his cum splattered her waiting mouth.

On board the aircraft, Captain Jenkins started his instrument checks while his cabin crew checked the seats, bathrooms and overhead lockers. As usual, Linsey started the seat-back media system and ran the safety briefing video through the cabin speakers.

The five cabin attendants were bombarded with a sickening blast of static and flickering light as all 150 seats simultaneously broadcast what the world would come to know as ASEC. In the forward galley, Linsey slumped to the floor as the code went to work restructuring her body and mind. She was a devout Christian and had only ever had sex with her husband, but as she emerged from her comatose state she found herself consumed with the thought of sex, of rubbing her lush new form against her workmates, hoping that they felt as she did, imagining their cocks, their mouths on her pussy. Her hands sought out her new, high, round tits and she felt the way her body was straining her uniform with unabashed glee. Where once she had been lean she was luscious and curvy. She clambered onto her long, toned legs for the first time and saw Gemma coming around in the fourth row of seating.

Gemma had been pretty before, but now she was a centerfold come to life. Her hair was thick and effortlessly glamorous, her eyes had grown large and heavy lidded. Her lips had thickened and bimboed out, and her tongue danced over them briefly, causing a shiver to run directly to her clitoris. She ran a finger over them and pushed it between their pillow-soft surfaces, and was soon sucking wantonly on two digits. Never the smartest or most focused woman, Gemma's brainpower had diminished and become rerouted purely for sex. She'd never again have a productive role in society other than as a pleasure drone - she would barely be able to hold a conversation without dropping to her knees to use her plump mouth on a dick or cunt.

Linsey was on Gemma in a moment, stripping their clothes and unfastening their hopelessly overloaded bras, kissing, stroking, sliding her tongue into Gemma's sweet, wet pussy.

In the rear galley, Danielle was grunting and straining as her small body expanded. Thick, strong arms tore through the sleeves of her blouse and her new broad back split her bra effortlessly. Her blonde bun fell from her head as testosterone flooded her system, hair follicles failing by the thousand. She lifted her now bald head as her face shifted, becoming unmistakably male. Pulling off the ruined upper garments, Danielle's horror at her changing body slowly became a leer of arousal as she felt her pussy begin to bulge and push into a new shape. Her skirt split up the seam as muscular thighs overwhelmed the material, and using her meaty new hands she tore it away. Underneath, her stockings were hopelessly laddered and frayed by the increase in her size. Her small, sexy panties, already stretched tight, were tenting as a large cock pushed out of Danielle's pussy. The silky fabric slipped off the slick new knob and settled at the base of the long, thick shaft. As two testicles plopped out, they got caught in the tangled underwear. Danielle tore it away and groped her new scrotum, ran her fist over and over her dick. Her mind spun as she acknowledged and accepted her new masculinity with glee. Cum sprayed from Danny's heavy cock, ropes of sticky, thick cream drizzling over the prone form of Frank, who had not yet awoken from his trance.

Frank's chubby body had become toned and lean, his face looking older and older until he'd gone from 23 to 45. But those years had brought a new handsomeness to him, and his thin blonde hair had become thick, dark, with grey temples. 

A thirty-something blonde woman, nude with fake round tits, bounced past the two men, plucking Danielle's old cabin crew cap from the floor and popping it playfully onto her head. As Danny helped Frank to stand and began lapping his own fresh sperm from his collegues cheek, he realised that the woman must have been Chris, changed just as he had been.

Chrissy, ecstatic in her new womanly body, found Gemma and Linsey entwined in the aftermath of their sex. She bent to kiss Linsey, and turned to Gemma. "Bring out the Captain and show him the film," she suggested, mischief playing in her blue eyes. As Gemma wandered off, Chrissy turned to Linsey. "I know what you have in your bag, Linsey. Get them out and we'll have some fun." 

Linsey reached up to the forward overhead storage where the crew kept their bags. Her rotations that day meant she was due for an overnight in Stockholm, which led to her packing for a night alone in a crew hotel. She unzipped and pulled out a sponge bag. Inside were two dildos and a vibrator. Linsey brought one to her lips, licked gently and smiled. "Which of your hot new holes do you want me to start with?"

In the cockpit, Jim finished his instrument check and peered out of the window, catching the eye of the dispatcher who had pulled up on stand. He gave a little wave to her, and she gestured back as she pulled her paperwork from the passenger seat. He turned to check with his crew and found the transformed Gemma naked but for her stockings, neckerchief and hat in the doorway.

"Captain, something's going on out here - you have to see it!" Jim, business-like as ever, pushed past the gorgeous woman to see what was happening. The looping hiss from the speakers filled his ears as soon as he was in the cabin, provoking a nausea so intense that he had to steady himself. With a hand over one ear, he turned to the master control to switch it off, but immediately froze when he saw the display screen. He stiffened, fighting to stay conscious as ASEC began its work. Lines and wrinkles disappeared from his hands and face, and his grey hair became shot through with youthful black. He grew, from an already tall 6'2" to 6'6", and the body which he kept in good shape for a man of 55 rippled with the hard, toned muscle of a man thirty years younger. Gemma helped him back to the cockpit, and sitting he found a final change occurring.

Jim Jenkins' secret shame, the thing that had kept him a bachelor, had let him focus so fastidiously on his work and the high standards he held himself to was changing. His tiny micropenis, thin and only an inch long, began to grow. He could actually feel it widening, thickening, piling on flesh, the skin being pushed to breaking point around his meat before it relaxed and caught up, then being pushed again. He fumbled at his pants and pulled them down his thighs in time to see the column of his huge, hard new cock sliding out of his body. With each new cell, each pulse of blood into the organ, each vein that sprang to life on it's surface, a new entitlement began to shape in Jim's mind. When his dick was puny, everyone respected him, followed him. But now he was carrying this huge log, people were going to have to worship him - he would demand it. Flexing his thighs, Jim realised he had something between them, and as he reached down he found a heavy pair of balls hanging, many times the size of his old ones. In the explosion of new nerves serving his penis, he'd entirely missed the sensation of his testicles swelling. Now his cock and balls had settled at bull-sized, he could feel them producing semen, almost feel them sweating out his scent. He was going to show everyone what a big dick really was.

Gemma had clearly noticed, and her hand joined Jim's on his scrotum. She slid down, grasping his dick and guiding it into her luscious, full-lipped mouth. He luxuriated in the sensation of his first ever blowjob, performed on his huge new unit by a gorgeous nymph. As her fat lips squashed around the sensitive cock head, Gemma felt his precum began to flow, and tasted it as it coated her tongue. She used the extra lubrication to slide the monster into the back of her throat, though even with her ASEC-gifted biology she couldn't get it any further. A strong hand snaked into her hair and lifted her head, and she found herself kissing the new hunk. Another reached between her legs, and with a dexterity that surprised her parted her pussy lips and began sliding over her clitoris.

She hissed in his ear; "Don't wait... I want that thing inside me..." He hoisted Gemma up effortlessly and slid into her.

The cabin crew had been joined by two members of the ground crew, who had boarded to ask why they hadn't yet signalled for passengers, and who had immediately fallen under ASEC's influence. One, a gruff ground handler, a thirty year veteran of the airfield, came repeatedly as his masculinity evaporated and he became a chubby princess with bright pink hair. The other, a young gate check staff, barely changed at all except for her ass, which swelled outrageously under her skirt, gaining a shelf-like projection behind her. They joined the crew, fucking on the seats and in the aisles.

Inside the terminal, Paul had recovered from his tryst with Nancy and taken her back to Security. As he struggled to come up with an acceptable excuse for the amount of time he'd taken that Jim would be satisfied with, he saw a group of staff gathered around a television in a crew room, looking shocked.

"...appears to be digital in nature, and relies on the signal being both heard and seen in order to effect the change. Again, we have deliberately shut off the visual broadcast from our newsroom to avoid accidentally spreading this signal." Sure enough, the screen was black. "The effect of exposure to the signal in adults appears to be a rapid transformation, sometimes involving an instantaneous change of sex, size and age, and an extremely heightened sex drive. Police are reiterating that it is unknown whether the infected are dangerous, but that they should be avoided if at all possible. Continuing advice is to turn off televisions, phones and computers and to switch to radio for more updates." Paul rubbed his forehead in thought. Was this what Nancy was? She actually was the Nancy he'd known for years, only changed? He headed for his aircraft.

On the top step sat a woman in what was left of a cabin crew uniform. Long dark hair was tousled and unkempt, and her large bare breasts glistened with sweat and... cum. She scooped it up with one finger and sucked, while beckoning to Paul with the other. If it hadn't been for the ball-draining that Nancy had just given him, Paul might have given in. Instead, he headed over to the ground power unit attached to aircraft's electrical system and flicked off the generator, then went back to the gate and dialled the flight operations office from the landline to make a report.

"Thanks Paul. There's nothing you can do here, you should head home - we won't be flying today. We're just glad you're already on the ground, really. The inbound from Stockholm is in the air, but we haven't been able to raise them on the radio. I hope to God they're okay..."
