Liam had been flying for nearly twenty years. He loved the job. Being in the sky always made him feel free, and even after tens of thousands of hours of flight time, he still got a chill during takeoff.

Today's flight was a routine cross country trip. His copilot, Sharon, was professional and quiet. She didn't like smalltalk when in the air. Liam, standing at 6'2", relatively muscular, his brown hair always neatly cut, was the same way, and appreciated her professionalism.

Flight had been hard on Liam's family life. His wife divorced him because he was always away, or so she claimed, but in the past several years had been dating exclusively women. She had been a lesbian the entire time. Liam and his ex were on good terms and coparented well. Nobody held any hard feelings over the breakup. Some things just weren’t meant to be and clearly, they weren’t right for one another.

 Since his divorce, he generally found it pretty easy to pick up women in the cities he visited. Unexpectedly, he also found that picking up men was just as fun. Deep down, he had always known he was attracted to both men and women, but he only acted on that attraction after his divorce. With his looks and his professional confidence and his outgoing demeanor, he found it easy to enjoy himself sexually after the breakup. These hookups were sustained largely due to his gift of having an abnormally large cock.

Throughout most of his youth he assumed that every boy had a size similar to his. He often changed in front of and bathed with his three older brothers who appeared to be about the same size as him. It wasn't until the age of eleven, when changing at the local pool, that he realized he might be different. Even before puberty, his flaccid penis was two or three times the size of the other boys he saw. They pointed and laughed, but as Liam went through adolescence, his member grew and grew to the point where he had trouble hiding his random erections. This led, at first, to some wildly embarrassing moments. In gym class, at 14 years of age, he accidentally exposed himself to his classmates. It was rope day. Other boys were climbing the rope one after the other. Most made it to the top, several didn't. When it was his turn, he easily climbed up the hanging rope. As he descended, his gym shorts bunched up and out flopped two egg sized testicles and a 6.5 inch flaccid penis. He could do nothing but continue to climb down, fully exposed, listening to his peers point and laugh and talk. Finally, he reached the bottom of the rope and quickly readjusted himself. His face red with embarrassment and near tears, he ran from the gym. Although he would love to forget this moment, he was reminded of it regularly throughout the rest of his time in high school.

A few years later, at sixteen, he experienced a similar level of embarrassment. His mother's best friend was visiting. She was beautiful. Perfectly athletic, impressively large tits, and a well toned ass. He was always attracted to her. During the visit, they sat down for dinner after a swim. The older woman was wearing a bikini top and a cover-up. Young Liam noticed that part of her areola was exposed. Her top had slipped slightly. His growing sixteen year old cock responded by immediately reaching full staff, hitting against the bottom of the restaurant table. By this time, he was a solid 9 inches erect. As the dinner continued at the local restaurant, he just got harder and harder. Finally, the bill was paid and Liam's parents, brothers, and his mom's friend got up to leave. Liam stayed seated.

"I'll meet you outside in a moment, don't worry," he claimed, but his parents pressed.

"Liam come on. It's time for us to get home," his mother replied.

After going back and forth for a minute, the argument gathered the attention of most people in the restaurant. Finally, his father pulled his chair back and yanked him to his feet by the armpits. Liam's gigantic staff jutted straight out down the leg of his tented swim trunks. His cock bounced up and down obscenely in his shorts as he was lifted off his feet. His mother blushed and looked away. His brothers laughed loudly. The mother's friend only stared, smiling. Liam noticed her licking her lips and turned beet red.

His father only got angrier, yelling "cover yourself up, Jesus Christ! You trying to show off here or something?"

The ride home was mostly silent, only broken up by occasional half hearted attempts at small talk. At home, his parents parked and carried the leftovers inside. His mother's friend got out of the van first and gave each of Liam's brothers a hug goodbye as they left the side door of the van. Each following the other to the front door.

Liam was last. the woman adjusted herself ever so slightly, so that her supple thigh pressed into his crotch. He felt her nipples harden against his chest as she hugged him tight. The embrace lasted for just a few extra moments, but it was enough for her to feeling his shaft twitch against her leg. She glanced down after letting go and turned. She casually extended her hand, grasping his cock through his clothing and dragged her hand slowly from base to tip as she walked away. Liam almost came as he felt her hand fall away. He disappeared to his bedroom for the rest of the night, unable to face his family. He pleasured himself repeatedly to the lingering memory of the woman's touch. He tried to forget how much of him everybody saw that day, but his memory of her accidentally exposed breast and the lingering hand on his manhood would always remain as a treasured moment.

The women and men he had in each city lusted after his ten inches of meat and hde enjoyed fulfilling that lust just about anywhere he landed.

He was a good father and his younger son, 19 still lived at home with Liam while going to college.

"Beep beep beep" an alarm snapped him out of his thoughts.

"I'm seeing some problems with the radar, directly ahead" Sharon reported

"Conducting a visual scan." Liam looked across the horizon.

After a short moment, he observed what appeared to be a glowing object or energy source. It got larger and larger. He realized it was heading directly towards their plane. "Evade!"

As he started to redirect he knew it was too late. The energy shot through the windshield as if it wasn't there and struck him directly in the chest, disappearing into his body. A strong tingling sensation spread throughout his body, dissipating after a brief moment.

"What the hell was that?" Sharon yelled, "instruments are back to normal. No damage to the aircraft is visible. I'm reporting to ground control now… are you ok, Liam?"

Always professional, he asked his copilot to take over so he could assess himself. The point at which the force struck him tingled faintly. As he rubbed his chest, he noticed his watch was loose. "That's weird" he thought to himself, "is my wrist smaller?" The tingling sensation returned, growing stronger

"Uhh, Sharon, I don't feel right…" he peeped. His voice sounded different to him. Softer? Higher?

Sharon made a request for emergency landing. As she turned to the other pilot, she let out a bit of a yelp. The tall man next to her was now clearly shorter in height. His uniform was bunching up. She couldn't look away as she saw him change in front of her eyes.

Looking at his hands, they were clearly smaller. As he rubbed his tingling chest he felt an unexpected softness where before was hard muscle. He felt the other side and felt the same softness there. Immediately, he realized what they were. "Ok growing breasts? What the fuck?" He shouted. Sharon stared at him in shock. Slowly, his new tissue continued to expand and grow, filling his small hands, then pressing outward further. He could feel his nipples through his uniform, clearly larger than before. He felt them stiffen, poking into his shrinking palms.

By now, the tingling has reached his crotch. "No no no this is all wrong," Liam cried as he felt the intense tingle reach his large manhood. His cock immediately reached full mast against his will, growing up and out of his now very loose uniform and into the exposed air of the cockpit. It reached more than halfway up his now much smaller torso and began slowly receding into his body. Liam grabbed his beautiful dick and moaned as it shrank past his still growing breasts, past his navel, back down into his clothing, and finally, nothing. Almost immediately, the feeling returned, but with a deeper frequency. He reached his right hand and felt his new sex forming in his palm.

"I have a pussy now?" He thought to himself in shock.

Liam looked up and realized he could no longer peer over the controls to see the flight path ahead. He couldn't be much more than 5'6" at this point. His body was shrinking in real time, at least most of it was.

He felt a pressure against his clothing. His breasts continued to fill out. His uniform was loose everywhere but I'm his chest. He tried to push his new breasts against his body, frantically and unsuccessfully to stop their growth. As the pressure grew further he grabbed his uniform shirt and ripped it open. His new assets bounced out, held back only by his thin white undershirt. As the tingle in his breasts continued he watched them stretch against the fabric. He could see his nipples through the fabric as they continued to lengthen and become thicker. They were nearly thumb sized at this point. He put his palms back onto them to push them back down, sending a momentary flicker of pleasure through his breasts. His small hands could barely cover his large areola.

As his watch slipped off his wrist, it fell to the floor with a thud. Looking at his copilot with shock he realized that he was now looking up at her. "I must be barely five feet tall," he thought to himself, "what am I going to do? I can barely reach the floor of the cockpit!"

Finally, the tingling sensation in his new body became weaker and weaker. The growth of his breasts slowed as he felt their undersides rest against his thighs. They were absolutely massive, completely filling his small torso and stretching his white undershirt to it's limit. He put his hands underneath them and tried to lift them up, but their heft kept him from raising them more than a few inches.

"Sharon, I don't like this…" Liam sighed in a light, high pitched, feminine voice. He passed out from the shock of his changes.

Sharon watched with fear and morbid fascination at the man changing in the seat next to her. As he passed out, Sharon noticed that his face was changing. Becoming smoother and feminine as his brown hair grew long and thick, draping behind him. His massive breasts bounced slightly in the vibrations of the plane.

Her observations were reported back to base in real time. Sharon was following information provided to redirect the flight and describing what was happening to Liam at the same time. The voices on the other side of the comms responded with incredulity, but agreed to the diversion and promised to have a medical team available upon landing.

Liam awoke to the force of landing. "Was that real," he asked himself? One glance down at his enormous chest answered that question. He felt sick. He unbuckled himself and fell to the floor on his hands and knees letting out a sob as the force of gravity pulled his nipples to the cold metal floor. They immediately responded by becoming erect. They were huge, larger than her own thumb and hard enough to almost be painful.

"Sharon, I need a doctor," he reminded his copilot in his feminine voice. "I don't even sound like me anymore!" Liam stood up, using his chair to support himself. His breasts jutted out massively, basketball in size or maybe slightly larger. Their weight pulled him forward slightly off balance. They engulfed a large portion of his chest, hanging down to slightly past his belly button. Their width was large enough that they pressed themselves outward. Sharon peeked at him as his back was to her, as he held up his uniform pants with one hand. She could clearly see a good portion of each breast on either side of the man's small frame. They bulged out beyond his arms and torso. She wondered to herself how he would navigate the narrow entranceway to the cockpit. Liam was absolutely dwarfed by her 5'6" height. He couldn't be more than 4'10" at this point. As he turned to her, he lost grip of his belt and it fell. She couldn't help but admire the tight round ass that the saw exposed. He quickly pulled his pants back up and blushed deep red. His features were not only feminine but youthful. He, at 42 had some wrinkles forming in his face, but the small girl in front of Sharon right now could have been mistaken for younger than 18. The thin and stretched fabric of the XL men's undershirt did little to hide the thumb sized nipples and dinner plate areola poking, rock hard out of the shirt, tenting the fabric.

Liam passed out again. They got to the gate and the medical team rushed in, putting the limp girl onto a stretcher. Her breasts spilled out sideways as she was laid on her back and strapped in. They covered her arms entirely and jiggled with every bump. As the unconscious Liam was rolled off the plane and past dozens of onlookers, members of the crowd gasped. A female EMT thoughtfully placed a blanket over the girl's chest. "This has to be some kind of prank, right?" They agreed with one another as they transported Liam to the hospital.

"Please find somebody who can help! There has to be something!" Liam yelled in his hospital gown. He woke up as they got to the hospital and wept quietly as the technicians and nurses took his vitals. He was just a hair past 4'10" and when he tried to step on the scale his breasts pushed against the wall in front. The nurse helpfully suggested to stand on the scale backwards and recorded his weight of 150 lbs. His nipples seemed to be permanently erect and his breasts ached. They hurt when he touched them, so he tried not to. Every touch reminded him of his abrupt changes.

Several hours had passed since the very first change and several more hours passed with tests, blood was taken, a CAT scan, and more. The MRI machine was a bit of a problem, as Liam's breasts spilled so far to the sides that two technicians had to push them together as Liam was moved into the machine. Their touch was humiliating and painful. "I never realized that women's breasts hurt so bad. He could feel them against his arms, taught and hard, his nipples painfully erect.

As he got back to his room to await test results he complained to the nurse, "I can't believe how painful having breasts is, how do women handle this all the time?"

The nurse, confused, asked "painful in what way? Having boobs doesn't hurt, though with the size of yours there may be back pain in your life.  Please show me where you’re having pain.”

Liam resisted for a moment, but relented and removed his gown. His gigantic tits rested heavily on his lap as he sat up on the side of his hospital bed. His breasts stuck out, hard and bumpy. His gigantic nipples announcing themselves to the room like angry red thumbs. The nurse approached and touched each breast lightly. Liam moaned in pain.

“Oh honey, I’m so sorry. You’re lactating.” The nurse grabbed Liam’s right breast at the areola and squeezed lightly, spraying a fountain of milk. The unexpected strength of the spray hit the nurse mostly in her face and chest. “Ahh,” she exclaimed. “I’ll see if we can get something to help, sugar.” Liam could do nothing but fall back into the bed and cry. The touch and squeeze from the nurse had activated his letdown reflect and his hard, engorged, milk filled breasts responded with continuous streams of milk spraying lightly but constantly from each breast. Liam felt his bed become wet and heard his milk splashing onto the floor but did nothing as he lay helplessly and distraught.

After several minutes, the nurse returned with a hospital grade breast pump and showed Liam how to attach it to the thick and engorged nipples atop each breast. She had to leave for a moment to get larger cups for the machine as the ones she had could not fit over the nipples on this man’s chest. Once the larger materials were installed, Liam’s breasts reacted to the pumping action of the machine by releasing torrents of milk. The twenty ounce containers collecting milk from each breast filled to the brim in just over five minutes. Replaced by the nurse, the second pair of bottles also filled over the course of the next half hour. While embarrassed tremendously, Liam did feel intense relief as his taught, engorged breasts slowly softened and the pain he was feeling dissipated. He felt more calm as the machine sucked on his nipples with regular tempo. Silently, he had to admit to himself that the machine pulling on his gigantic areolas actually started to feel pretty good. He felt warmth and a hint of wetness in his crotch, but pushed the thoughts away.

Days passed in the hospital. Test results came back that he was healthy and strong and his body checked out normally on every test as a young, adult female, age unknown. Doctors discussed and agreed that Liam’s body was between 16 and 20 years of age. They had no answers. The days started to fall into a routine as Liam woke up to painfully engorged, milk filled breasts leaking onto his hospital bed. He would pump himself, which he was starting to enjoy, shower, watch TV, call and speak to friends and family, deal with insurance and work, pump his breasts again in the early evening, and go to sleep with the help of medication.

He did his best to assist in the investigation into the incident. Flight investigators at first could not believe what they were hearing from his copilot, but after reviewing the black box and flight audio recordings, they finally found the observations to be credible. Nobody knew how or why this had happened, and nobody knew how or if it was possible for Liam to return to his old body. After ten full days in the hospital

After the evening pumping session on the fifth day, Liam finally built up the courage to explore the warmth in his crotch that arose when milk was removed from his tits. He unhooked the cups from his nipples and rubbed them with his hands, expressing a little more milk and shivering at how good it felt. He laid back in his hospital bed and reached down towards his new set of genitals. His tits were in the way, so he rolled himself to his side a little bit, used both arms to pull his right breast out of the way and slid his arm underneath. Laying back down, his arms felt pinned to the bed by the weight of his mammary tissue, but he could reach the warm, wet slit, which was crying out for attention. He slid a couple fingers from his slight and small hand into his vagina and gasped at the feelings coursing through his body. While exploring, he came across a small nub of flesh at the top of his opening. It caused him to shiver with joy as he began rubbing his clit. After only a moment, his first orgasm as a female wracked his small body. He cried out loud in surprise at the feeling, and felt his nipples contract, followed by the feeling of milk dripping down the sides of each breast. Out of breath, he thought “ok, as bad as this all is, maybe there are some things I can get used to.”
