AUTHOR'S NOTE: This is my first attempt at a story and I wanted to clarify one thing. This is at its core a transfem MTF transformation story. As a trans woman I have some experience with the feelings, emotions, and hurdles of this, but I absolutely do not have a cis woman's perspective on anything. There will be sex and body exploration moments, and as someone without a vagina I had to research what this is like. Hopefully it doesn't come across like some dumbass virgin wrote it. Anyway, I hope you enjoy

Chapter 1: In Which She Makes a Wish

Ryan stared in awe at the being hovering before him, a beautiful woman with long flowing chestnut colored hair held in a ponytail by a turquoise band, a matching bedlah top covering her chest, and gold bands around her wrists. Piercing blue eyes regarded the boy, a hint of a smile touching them. However the most notable thing in Ryan's estimation was that just below the navel her body ended and below that she was made of a lavender smoke that endlessly emanated from an ornate antique bottle, twisting and flowing in eddies and swirls that seemed to hypnotize him as he beheld the being before him.

“Well met, Master,” intoned the strange ethereal woman. “I am known as Sisu the Giving, genie of the bottle. I give you my most humble thanks for freeing me. In return I shall grant you all your heart’s desires. May I ask the name of my Master?”

Ryan stared slack-jawed. He had found the bottle in an antique shop tucked away in an alley that he’d never meant to go down in the first place. He’d bought it as a gift for his girlfriend’s birthday. Andrea loved antiques and Ryan had thought she’d love the bottle especially, but when he pulled out the stopper this was the very last thing he’d expected to happen. Finally after a moment of stunned silence he spoke to the genie before him.

“I’m, uh, Ryan,” he said lamely. “You…you're really a genie? I mean, uh, obviously you must be, but…I didn't know genies were real.”

“Indeed I am,” Sisu the Giving said. “Alas, my kind are rarer in this age. I can feel only three others of my kind left in this world. Many of us have passed to realms beyond, or shall never be found again and have wasted away. ‘Tis a great tragedy, but unfortunately not one that I may remedy, for my bond is to you, my Master. As he who has freed me I am bound to your eternal servitude. As they say, your wish is my command!”

Sisu smiled brightly and twirled in midair as bright glittering sparks flew about her from her fingertips, painting her as the very picture of ethereal beauty. Ryan was awed by her, still hardly believing what was happening.

“Wish? You mean you can really grant any wish I want?” he asked.

“Of course, my Master! I shall grant anything you desire. Fame, fortune, love, anything you ask of me shall be yours!”

Ryan paused, suddenly wary. “Hold on,” he said cautiously. “In stories genies aren't always so kind in granting wishes, there's always some kind of twist.”

Sisu’s eyes twinkled as she regarded her new master. “Indeed,” she agreed. “Many of my kind have done these things. I, however, shall not warp your wish into some unfavorable or nefarious outcome. Your wish shall be granted perfectly and according to your true desire.”

Ryan waited for a moment for Sisu to speak. “But…?” he prompted.

Ryan considered this. If what Sisu was saying was true it wasn't as bad as the stories had said it would be. However, this could potentially be just as bad, especially if he didn't know what he'd have to give up. Still, the trade-off might be worth it in the end after his three wishes were through. Actually…wait a minute.

“Wait,” he exclaimed as the thought occurred, “you haven't told me how many wishes I get!”

“That is because there is no limit,” Sisu proclaimed. “I do not limit you to one, three, or even five as some of my brothers and sisters may have. You may decide yourself when the price becomes too high for you to ask for more.”

Ryan paled slightly. These trades must be pretty serious if Sisu thought he would give up on his own accord. What would be the breaking point? What would be taken from him that would cause him to quit? And just because something wasn’t harmful doesn’t mean it couldn’t be bad.

“That's…different,” he muttered uneasily. “Is there anything else I should know? Any more rules like no killing or no love?”

“Nothing of that sort. Love is easy to manipulate, even if it can get a bit unpleasant. If you truly wish someone to die then it shall be done, but the price of ending a life shall be severe.” Sisu’s eyes turned steely and sharp. Ryan could see the weight of her words reflected in her expression as she spoke.

“I would also caution against raising the dead,” the genie continued. “It can be done, but things tend to get…messy. Besides these, I give you one final warning.”

The swirling smoke comprising Sisu's lower half suddenly shifted inward and formed into slender legs with a gold and turquoise pair of pants to match her bedlah top. Sisu touched down on the floor and took one quick stride to be face to face with Ryan for the first time. She stood at eye level just a few inches away and Ryan instinctively took a half step back.

“What is done cannot be undone,” she warned, the severity shining in her eyes once more. “Neither wish nor sacrifice may be reversed. What you get and what you lose shall remain for all your life. Choose wisely.”

With her warning completed Sisu floated back up into the air, taking a pose as if she were lounging on a chair, her head propped on her arm and her legs crossed, all trace of seriousness gone. Ryan swallowed nervously.

“So, my Master,” she smiled. “What is your wish?”

Ryan regarded the genie nervously. A pit had begun to form in his stomach as he weighed the choice before him. He could have anything he wanted. But was it worth the risk? What could he want so bad that it would be…

He paused, and the pit grew deeper. Ever since the lavender smoke began pouring from that bottle a thought had played at the back of his mind, a thought that had grown stronger even as Ryan tried to shove it down, shove it back into the dark place of his mind where he kept it locked. Some days it stayed put, content to stay away, but it was always there, waiting, and on the nights when it broke free it consumed him and left him aching, sleepless, and hopelessly despairing. But now there was no avoiding it, and 27 years of repressing this feeling had finally taken its toll. It was free now, and the thought, that terrible ache, could be made real, and almost without even thinking Ryan spoke.

“I…can you…” He hesitated.

“Hm?” questioned Sisu, a curious look on her face. “What is it that troubles you, Master?”

Ryan could hardly breathe, he felt like he was being choked. He forced himself to take a deep breath and count in his head until he was calmer. 1 and 1 is 2. 2 and 2 is 4. 4 and 4 is 8.

“I wish…” he started. 8 and 8 is 16. 16 and 16 is 32.

Sisu smiled, and unbeknownst to Ryan she used a tiny portion of her magic to loosen his tongue. She had a sneaking suspicion what his wish would be. It was not the first time she had seen this happen.

“Speak, Master,” she intoned.

Ryan counted 32 and 32 is 64, took a deep breath, let the pit fill his entire being, and spoke.

“I wish I was a girl,” she commanded.

Sisu did a midair somersault and landed in front of Ryan, her eyes glittering and her grin wide. Just as she’d suspected.

"Your wish is my command, Mistress.”

Smoke poured from the bottle, surrounding Sisu until she was no longer visible. At once the column of lavender haze drifted towards Ryan, enveloping her in a soft caress from head to toe. She shivered as she felt herself begin to change. Her short hair grew, lengthening to halfway down her back, light and smooth. Her shoulders and waist began to narrow at the same time as her hips began to widen. She suddenly felt very tight in her jeans and worried about them ripping as she felt her butt also begin to expand. She couldn't be too sure through the smoke but she could swear she felt herself shrinking.

It was all too much. She could hardly breathe. It felt as though there was a heavy weight on her chest. She put her hand up and gasped, feeling the mounds beneath her shirt as her new breasts began to swell. She was suddenly very scared of how she hadn't specified anything about this, but there was nothing to be done now. Just as she was beginning to worry that they were going to get too big the swelling slowed and stopped. She breathed a sigh of relief, but tensed again as she heard Sisu’s voice in her ear.

“Apologies, Mistress, this next part is going to be a bit invasive, but I need to be precise here. I promise I shall be gentle and make it nice for you.”

The smoke receded from her head and feet, gathering at her crotch and moving into her pants. She squealed in fright as she felt her manhood begin to shrink, then let out a soft moan as she felt pleasure radiate from it. She shook and her knees buckled as she suddenly felt the greatest orgasm of her life rock her. Pure ecstasy radiated out from her crotch as she sat on hands and knees, unable to move as the genie continued her work. It came in waves in ways she had never felt before, reverberating through her whole body, shaking her to her core. As the bliss rolled over her she felt the genie moving deeper and deeper inside her new genitals. She could feel things inside her moving, being rearranged, transformed from her previous male organs to her new female ones. Soon the waves of pleasure subsided and she was left panting on the floor. Eventually she was dimly aware of the smoke coalescing in front of her as Sisu appeared again, looking proud and grinning from ear to ear.

“I must say,” bragged the genie, “that this may be my greatest work in centuries.”

Ryan looked up at Sisu, eyes wide, still catching her breath.

“That…that was…” she panted in an unfamiliar high-pitched voice.

“I’m really quite good,” the genie said, evidently very pleased. “Still, we're not quite done. There's one last finishing touch.”

Ryan cocked her head to the side. What could possibly be left? Everything about her was fundamentally different now, even the world looked bigger.

“What-” she started before Sisu knelt down, took her head by the chin, and kissed her firmly on the lips.

Ryan's eyes went wide as suddenly thoughts, memories, and knowledge flashed in her mind. How to put on makeup, how to wear a bra, how to manage a period, everything one could ever need to know about being a woman was beamed directly into her head. At the same time Ryan felt something else leave her mind, some small piece of former knowledge taken. Was this the trade?

Sisu broke the kiss after just two seconds, though to Ryan it had felt like an eternity. She wobbled slightly on hands and knees, then fully collapsed on her side, whimpering, the room spinning above her. Sisu drifted down to rest beside the poor girl and placed Ryan's head in her lap. The genie began to stroke Ryan’s hair and spoke softly to the new girl before her.

“It is alright, Mistress. You have been through a lot. Just breathe and it will pass.

Sixty…sixty-ffffff… Ryan's head was still swimming with the process and couldn't really focus properly on her numbers. But as her head began to clear she tried to focus on what was taken from her mind, something important, something she felt like she had all her life that was now missing, but no matter how hard she tried she couldn't remember.

“What was it?” she asked the genie unsteadily in her new higher, softer voice. “What did you take?”

Sisu smiled down at Ryan. “Nothing too important. You'll find out soon enough.”

Ryan blinked up at the genie. She was beautiful, and from here she looked almost motherly. As the last of the head fog cleared, Ryan sat up as straight as she could, if a bit unsteady, next to the attentive genie. Did Sisu get bigger? Or did…

Ryan propped herself on the coffee table and slowly pulled herself up. Sisu stood and offered a helping hand which Ryan took as she took stock of everything. No, she wasn't imagining it, Sisu was taller than her, but only because Ryan was shorter. She had been at eye level with the genie before but now Ryan had lost at least eight or nine inches. Even her clothes hung weird and her jeans bunched up considerably around her ankles and under her heels. She'd have to have Andrea measure her when-

“Andrea!” she squealed at the thought of her girlfriend. “What's she going to think seeing me like this?! I didn't even think about how she'd react! Sisu, change me back! She’s supposed to come over tonight!”

Sisu gave a tsk tsk noise and wagged her finger at the girl. “Apologies, Mistress, but as you recall one of my rules was that wishes cannot be undone. I believe there's a delightful phrase in this time, ‘no take-backsies.’”

Ryan groaned. Of course, stupid stupid Ryan, never thinking ahead. What was she going to do?

“If I may, Mistress,” Sisu said, “I'd advise you to worry less about your girlfriend and more about yourself. You seem to be having some…difficulties?”

Ryan looked up at the genie, still helping her stand, wondering what she was talking about, when she suddenly felt something very warm between her legs. She looked down and jumped back in alarm as she saw a growing wet stain around her crotch that was beginning to run down her legs, completely soaking the front of her too-tight jeans. It took a second for her to fully realize what was happening, but when she did she was utterly mortified.

“What the fuck what the fuck!” She shrieked. She tried desperately to put her hands between her legs in an attempt to stop it, but to no avail. Under no control of her own she was wetting her pants and could not stop.
