Courtney slipped into the darkened room. The 30-year-old nurse with the blonde pageboy haircut had infiltrated the clinic months ago, waiting for the chance to undermine or expose their perversions. God didn’t make mistakes! Men were men and women were women, and no scientific breakthrough would change that.

She approached the sedated figure on the bed and pulled back the covers, revealing the poor woman’s body. Morgan had come to the clinic weeks ago...

“And you definitely haven’t taken any artificial hormones?” Dr. Straub steepled his fingers as the fifty-year-old professional beheld the plain young man who had been assigned female at birth.

Morgan shook his head, his short, tousled brunette hair shifting with the movement. “No, my parents wouldn’t let me, even though I’ve been binding these for a few years.” He gestured to the slight bulge visible through his bulky sweater.

“All right, excellent. You’ll need to speak to Dr. Chen, our psychologist, to make sure you’re mentally and emotionally prepared,” he gestured to the late thirties Chinese woman next to him, who gave a nod, “and Courtney will take some blood.” At his direction, the blonde nurse came forward...

Courtney pulled out a syringe, except this time it was already full of something: artificial female hormones, the one thing that Dr. Straub was worried about, which gave her the idea that it was exactly what she needed to reverse the treatment Morgan had received. However, she paused ... she didn’t want anyone spotting the injection site. Looking at Morgan’s breasts, she smiled, lifted one up, and injected half of the syringe underneath. Then she lifted the other and injected the rest there. There was no way those breasts were going away now! Then she frowned ... she should have injected some into Morgan’s vulva as well, but the syringe was empty now. Well, the hormones would go all the way through the confused woman’s body, so probably the location of the injection site didn’t matter.

She pulled the blanket back over Morgan and slipped from the room.

Months previous:

Dr. Straub’s pretentious smile beamed at the women from the big screen TV in the basement of their church. “My treatment will effectively reverse puberty, returning the patient’s body to a state where the second sex chromosome can be artificially set to X or Y, at which point their body will ‘course-correct’ as it enters a second, accelerated puberty. With this, transgender patients can actually change their body to reflect their mind, canceling out gender dysphoria and the many issues that can stem from that psychological disorder, including feelings of depression that can lead to self-harm or suicide. I thank the medical community for their consideration.” Then the screen froze, catching the doctor with one eye closed, making it almost look like he was winking at his conservative audience.

Mrs. Henderson, a thin, 40-year-old auburn-haired woman, harrumphed and stood up. “What perversion! What presumption! This man fancies himself a god among men.”

The other women, including Courtney, nodded their heads in agreement.

Today:

Dr. Straub, with Courtney alongside, strolled into Morgan’s room. The young transgender man had been sedated for the last few days for his own peace of mind as his body modified itself. While the process shouldn’t have been painful, Dr. Chen was worried about the psychological effects of experiencing so many constant, dramatic physical changes over so short a period; better to fall asleep and wake up in your ideal body instead.

“Let’s see ... hm ... patient’s Adam’s apple doesn’t seem to have shown itself yet.” He pulled back the blanket and frowned. “Breasts haven’t decreased in size ... in fact...” He took a closer look. “Have they grown? Have them measured,” he directed Courtney, and she wrote it down while trying to keep a straight face.

Dr. Straub pulled the sheet away from Morgan’s hips and Courtney couldn’t hold back her gasp. The young transgender man’s vagina was gone and a 3-inch pink penis jutted out with a small, hairless ballsack below. “That’s more like it,” Straub commented as he lifted the small member with a gloved hand and examined the scrotum. “Hopefully it’ll get bigger, but we both know that some men just aren’t as lucky as some others, eh, Courtney?” He gave her a quick smile.

She could feel her face flush. She didn’t have a boyfriend currently, but the ones she’d been with were ... normal-sized? She was reminded that the older physician was gay and didn’t want to think of him touching another man like that. The bible was very clear on that subject.

He pulled up the blanket and took a closer look at Morgan’s face. “His acne has cleared up, and ... does he look ... prettier to you?”

Courtney stepped forward to see ... sure enough, Morgan’s previously-plain face did seem more feminine. She told the doctor so and then caught a strange, musky scent before she became momentarily dizzy. She put out a balancing hand onto the bed as she swayed, but Dr. Straub was already striding toward the door. Well, I’d best measure those boobs, she thought, and went looking for some measuring tape.

Morgan floated in a soft mist, euphoric. He felt strange but good between his legs ... no, further down than that, where he’d never felt anything before, like his clitoris when he played with it, but ... lower? The feeling grew and grew, like he had to pee but not quite, and then he grunted as pleasure he’d never experienced before burst from his loins, pumping up and out...

He blinked awake as he heard a high-pitched grunting and then felt a cooling sensation between his legs as the bed shifted. He looked down to see breasts ... breasts?! Those were supposed to be gone! He touched them and gasped at how sensitive they were, and they were actually bigger now! He sat up to look between his legs. There, sticking up from his crotch and glistening, was a hard, pink penis, maybe four inches in length. “Yes!” he exulted, but his voice hadn’t deepened like the doctor said it would.

“Oh, you’re awake,” a female voice said from off to the side.

Morgan looked to see the blonde nurse -- Courtney? -- kneeling on the floor, wiping her mouth. “What’re you doing down there?”

The nurse stood up quickly and swayed. “Just ... checking...” She held up a roll of measuring tape and her tongue darted out to lick at the corner of her mouth. “Mmm...”

“Checking what?”

Courtney tore her eyes away from Morgan’s insistent erection. “Uhm ... what?”

“What are you measuring?”

“Oh ... those.” She pointed at Morgan’s breasts.

Morgan felt his face go hot. “I’m not supposed to have these anymore! Go get Dr. Straub!” He pulled up the blanket and lay back in a huff.

“Um ... okay.” Courtney rushed from the room.

Dr. Straub examined the still-unconscious form of his other patient, Lucy, an 18-year-old, brown-haired transgender woman who had undergone the procedure the day after Morgan. Yes, the professional nodded, everything was proceeding as expected: the penis had dwindled into a large clit and the scrotum had turned inside out and been pulled inside the now-female body. He pressed the ultrasound sensor where it confirmed her core had been hollowed out to form a uterus, and though he couldn’t see it, he knew that the testicles were shifting and transforming into ovaries. This newly-minted young woman would even be able to bear children one day, if she wished. Wouldn’t that be something?

He had started the examination low, but moved up the young woman’s body. The previously-male muscle definition could still be seen in her midsection, though he expected that would soften as the process continued. A-cup breasts were pushing out from her chest and, based on her 5’10” frame, would almost certainly grow larger. He was excited to measure her height once she got back on her feet, to see if she shrank due to the inverted second chromosome. He noted that the Adam’s apple was less prominent, and then confirmed that Lucy’s mannish features had softened, her jaw becoming less prominent and her lips more full. Yes, no problems with this patient, he nodded to himself, unaware of Courtney’s interference in Morgan’s development. The saboteur had only managed to sneak one dose of hormones in, so Lucy was untouched.

“Dr. Straub?!”

“Courtney? What is it?”

“Morgan’s awake and wants to see you.”

“Ah, excellent.” He pulled up Lucy’s blanket and headed back to Morgan’s room.

The doctor accepted Morgan’s tirade, assuring the young man that they would figure out what was going on with his breasts as soon as possible. Noting that the increase in testosterone was most likely fueling the boy’s assertiveness, he made a mental note to get Dr. Chen to speak with him very soon.

“What is his chest size?” he asked the nurse outside of the Morgan’s room.

“Oh ... I didn’t measure it yet.”

The doctor sighed. “Go and do that now ... and also have him shower ... there’s an odd scent permeating that room.” He twitched his nose and frowned in recollection.

“Yes, Doctor.” Courtney stepped back into the room to see Morgan, naked, standing in front of the tall mirror in the room, stroking his new cock. “Oh! Uh, the doctor would like me to measure your chest and says you should shower.”

“Okay.” Morgan turned, showing off his now 5-inch erection, completely at odds with the perky C-cups jutting from his chest. He noted the nurse’s nostrils flaring at the sight. “Why don’t we do both at the same time?” He crooked a finger, directing her to follow him into the adjoining bathroom.

Courtney grabbed the measuring tape from where she’d left it and followed. Morgan lifted his arms and she determined that, yes, his bust had increased from 30 to 36 inches.

“Tickles...” Morgan commented as he stepped into the shower and turned the water on. “Mm...” The warm water felt good. He looked to the side to see Courtney hadn’t left yet and her eyes were fastened to his hard cock. “Why don’t you measure this as well?” He helicoptered it a little, delighting in the strange sensation.

“Uh, okay.” She stepped forward with the measuring tape, barely noticing the water hitting her as she confirmed his new 5-inch length.

“Stroke it ... compare with your previous boyfriends.”

She did so ... it was a little thicker than when she’d sucked him off earlier. Her mouth watered.

“Oh, look, you’re getting your clothes all wet. Why don’t you take them off?”

She could find no fault in that logic, and was soon naked as her hand skimmed along his erection.

Morgan looked down at the woman. It was hard to tell while she was wearing the shapeless scrubs, but she had an hourglass figure without being fat, with C-cup breasts that weren’t as perky as his, but that was okay. He took the lost-looking woman’s hand, pulled her to her feet, and kissed her.

“Ohmm...” Courtney hummed into his mouth. So muddled was her head, she didn’t notice as Morgan pushed her back against the tile of the shower. Then his hands were under her butt, lifting her up and spreading her legs, and she felt hard cock pressing into the very wet folds of her underused pussy. “Mm!” she moaned, still kissing him as Morgan slipped most of his new cock inside her. “MM!” Yes, this was what her body wanted, had wanted since she blew him earlier.

“Oh, this feels incredible,” Morgan commented as he broke the kiss and nuzzled into her neck, “like I have a huge clit and I’m stroking it deep inside you.”

“Mmhm,” Courtney agreed as she felt a small orgasm wash over her.

Morgan had never had sex, his gender dysphoria always interfering with any such idea, but his new body seemed to instinctively know what to do, alternately grinding his crotch into Courtney’s before pulling back to thrust inside more. He could feel something stirring inside his growing balls. “Ohh...”

Courtney realized that Morgan was going to cum and had a moment of panic until she felt his firm breasts pressing against hers. A woman couldn’t impregnate another woman, of course! Relieved, she lay back as she felt her own orgasm rising where that hard cock was rubbing along her needy insides. “Mmm...”

“Ohh...” Morgan thrust into the brain-addled woman faster, harder.

“Mmm...”

“OHH...”

“Mhm...”

“UGHHAAHH!” Morgan felt that magnificent feeling of his male orgasm rush up his shaft and blast the nurse’s unprotected insides.

“OHHUHH!” Courtney came hard as she felt Morgan’s hot cum burst inside her and wrapped her extremities around him. “UHHH! Yesss...”

“Sooo ... gooood...” Another spurt ... another...

“Yeahh ... ohhh...” Courtney’s welcoming body accepted every last drop of Morgan’s second-ever ejaculation.

He let the nurse back down to her shaking legs. “Don’t tell anyone about this, and we’ll do it again soon.”

Courtney nodded.

Lucy cried in her bed as she looked down at her newly-female body. “Doctor, it’s wonderful! It’s ... right!” She couldn’t believe the sight of her little pudendum, bare due to the reverse puberty she’d gone through. She palmed her A-cup breasts. “These’ll get bigger, right?”

“Yes, though it’s hard to say how big; everyone’s different, after all.” Dr. Straub advised her with a big grin. He was going to be so rich!

Later, after both patients had dressed up in their street clothes (though Morgan didn’t bind his breasts), they introduced themselves in the common area and compared notes. Lucy told Morgan that she hoped her breasts would get as big as his, as they looked beautiful.

They found a chess set and played a few games ... though Lucy won the first game handily, she found that she was having trouble concentrating after a bit and lost the next two.

Lucy woke to find Morgan standing next to her bed. “Oh, hey. Uh, you smell nice.”

Morgan sat down on the bed next to her. “Thanks. Have you ‘jilled off’ yet?”

Lucy blushed. “Tried a bit before going to sleep ... had a little orgasm, I think.”

“You think? Well, if you’d cum, you’d know. I know my way around a vagina ... why don’t I help you out?” He pulled her covers back, showing off her still-developing femininity. Lucy’s hips had rounded out a little more, her midsection a little slimmer. Though her breasts still seemed the same size, Morgan noted that her areolas were more pronounced as they firmed up in the cool air.

“Um, okay.”

“Cool.” Morgan licked his fingers and brought them down between Lucy’s legs, rubbing at her pussy lips and brushing up against her clit, which was still larger than expected.

“Oh wow.”

“Mm hm.” Morgan leaned forward and kissed Lucy, and while the newly-minted young woman had no interest in men, her new friend had the face and torso of a beautiful woman. While kissing her, Morgan slipped a finger inside Lucy’s virginal hole.

“Mmh...” she moaned into Morgan’s lips.

Morgan pulled back. “I’m gonna use my mouth, okay?” He shifted onto the bed between Lucy’s legs without waiting for a response.

“Ooohhh...” the girl moaned and lay back as her new friend’s tongue delved inside her fresh pussy.
