So I wrote the transformation and since character was a passenger, had AI right the begining and ending scenes, hope you like

The corset was tight around her chest, but not on purpose, it just seemed to do that. The waist was even tighter than before; the skirts were longer and more elaborate, the ruffles at the bottom of them were like black lace curtains. She wore a pair of black stockings that went up to her thighs with little bows attached at the ankles. Her shoes were high-heeled platform boots that came up almost to her knees and had studs running down the sides; they made her feel so tall!
She stood in front of the mirror for what felt like hours admiring herself. What she saw there was a beautiful young woman who looked like she belonged in an old Hollywood movie... or maybe better yet, one from the Victorian era. A girl like this could never belong anywhere else except at a ball or some other fancy affair. She could not help but smile. This was so much fun!
All her friends thought she was crazy when she told them about how she planned on going out dressed like this. They all tried to talk her out of it, telling her that no one would ever take her seriously if she did that. But Anna knew that everyone would be looking at her because she looked like a princess from another world and not a real person. No one would notice anything else. That's the way she liked it.
"Just think," she said to herself. "In an hour I will step outside and people will look at me and stare. Some might even point and whisper behind their hands. And then they'll say things like: 'Oh my God, what is she wearing?' and 'Can you believe it? She thinks she can get away with that!' and 'It must have taken her days to prepare.' It might make them laugh, but they'll also be impressed."
She finished adjusting her bustle and sat down on a chair. Her reflection smiled back at her. Everything was perfect. There was nothing left to do now but wait. She closed her eyes and took several deep breaths. Suddenly, she heard her doorbell ring. She jumped to her feet again and ran to the door.
When she opened it, there stood her best friend, Natalie. She was dressed similarly to Anna, though her outfit was less fancy and more gothic in nature. Her dark hair was tied back into two long braids. She wore thick black eyeliner and mascara, both of which complemented her green eyes beautifully. As usual, she was dressed head to toe in black, and her clothes only added to the image of her being a vampire.
"Hello," said Natalie. "I'm sorry I'm late. But I brought you something."
Anna looked puzzled. "You didn't have to bring me anything," she said.
Natalie laughed. "No, you're right. You don't have to accept gifts. But I still wanted to."
Anna smiled. "What did you bring?" she asked.
"Well..." Natalie began. "I know you said I shouldn't bring any presents, but I couldn't resist." She reached inside her bag and pulled out a small piece of paper.
Anna read the note. It said: "A present for a beautiful girl. From a mysterious stranger."
Her heart beat faster. She grabbed the gift and tore off the wrapping paper. Inside was a small jewelry box.
"This is beautiful!" exclaimed Anna. She picked up the box and admired the intricate design on its lid. The wood was a rich red and very smooth to the touch. It wasn't painted, either. Instead, tiny carvings had been carved into the wood, making it look very old.
Inside the box was a necklace. It was made from a single strand of pearls that ran from a metal clasp to a decorative charm that hung from a thin gold chain.
"That's amazing!" said Anna. She put the necklace on and held it up against her dress. Perfect!
"Thank you, Natalie. That really means a lot!"
Natalie nodded. "Of course. Now let's go."
They walked out of the apartment and down to the street.
"Where are we going?" asked Anna.
"There's this new club," Natalie explained. "It's supposed to be really cool."
"Sounds great," said Anna.
They arrived at the club and Natalie led her inside.
Anna gasped. "Wow! It looks like a scene out of a movie!" she exclaimed.
The club was decorated to look like an old mansion. Chandeliers hung from the ceiling, making a beautiful glow over everything. The walls were covered in paintings of various styles and periods. There was even a fireplace in the corner that had been turned into a dance floor. The music was loud and pulsing, and it echoed throughout the room.
"It's awesome!" said Anna. "Look at all these people! Do you think anyone will recognize us?"
Natalie giggled. "I doubt it," she replied. "We don't exactly fit in here."
Anna laughed. "Yeah, you're right!"
As they moved through the crowd, they soon noticed that most of the people there were dressed in a similar fashion to them. A few people looked shocked to see them, but most of them just ignored them. It was odd, but Anna actually found it comforting.
After a while they ended up dancing with a group of girls. Annna excussed herself and walked to the bathroom.
She closed the door and was in the room alone.

Richard looked up at the reflection, how many days? How long did he think he was this prissy little goth? The corset felt strange and tight. He felt his back arch and pressed against the wall. His ass ached and his head hurt. It was too uncomfortable to keep standing, so he sank down to sit on the toilet seat and closed his eyes.
He was tired, so tired. The last few years had been so hard. All he wanted was to go home. To sleep for a thousand years and be back where he belonged. THis curse this damn curse made it impossible for him to leave this place. He was trapped.
It had been a one time mistakee, he hadn't meant to cheat. Why had he gone to that bar? It was the first time he'd been there, why had he chosen that night to drink? He hadn't been drunk, and he knew that he wouldn't do something so stupid sober. He'd seen the girl, she was just so unique in her black lace gown. So beautiful, so pure. He had to have her.
He couldn't explain it, he had never done anything like this before. But he had to. When he saw her, he felt the need to touch her, to taste her. He wanted her, and he would have her.
The next morning, he awoke alone, feeling so ashamed. He should have known better, he thought. One drink and he was gone. He had been so weak, falling for her beauty. He'd even kissed her, holding her close. What kind of man did that?
But she was gone and there was no one to answer his questions. Just a short note saying he was going to be sorry sorry, but it was too late.
It started as a apin in his foot, it felt tight as it was compressing down. Shrinking and twisting into a tiny new shape, a dainty one. The pain became worse and worse as it twisted and turned down his leg. Soon he could barely walk, but the pain was so intense his limb crunching down. Changing from the hard muscles of a man to the soft gentle curves of a girl.
The transformation was painful and it took hours to finish.  Once his legs finished it move to his pelvis, breaking into a new shape and flaring out wide and womanly. His cock shrank down to a small shriveled thing, and soon he was completely female.
He lay there in bed, feeling so drained. His body felt heavy as his torso compressed, each bone shattering in agony only to quickly reform into a new shape, A far smaller shape. The change was slow and agonizing. Finally his arms broke and reformed into delicate feminine limbs, his shoulders slimming down and becoming more narrow. His breasts were small and firm, with nipples that were hard and cold.
Finally he was done. He was a woman, pretty petite slip of a girl on the cusp of adulthood, probably only 19
He looked at himself in the mirror and smiled. He looked like a girl, his face was beautiful and pure. Then his clothes, the moved as if alive, becoming dark and lacey. Tight and constricting, nothing like any outfit he'd worn before. But it felt right.
How did this happen?
He wondered. Did she come back to visit? Was this the girl from the bar? Maybe his curse had finally broken. Or maybe it was a dream. He walked out and down the stairs. IT wwas then the true horror. He had no control, this female form, was under new control. Sure he felt everything, but unless she was utterly alone, he had no control. Her thoughts were his thoughts, what she wanted was what happened. And just like that Anna arrived.
**
Anna came back to the party. She couldn't believe how crowded it was! So many people, dressed so beautifully. She stopped to admire a dress that looked like it had been made by the same designer as hers. She smiled at the girl whose dress it was, and she smiled back.
"you ok" said Natalie.
"Fine" said Anna.
She continued walking down the hall. Suddenly she bumped into someone and fell backwards onto the floor.
"Are you alright?" asked the person who'd bumped into her.
"I'm fine" said Anna. "I'm just clumsy. Are you ok?"
The person looked at her curiously, then smiled. "Yes, thank you" he said. He was cute the perfect strong type she liked. His face was handsome and chiseled, with deep blue eyes. He looked like he worked out regularly and it showed in his muscular build. He wore a black tuxedo and a white shirt underneath. His hair was a dirty blond color and styled neatly.
"Thanks again" he said.
"No problem" said Anna.
They both stood up.
"So, I'm Tim, nice to meet you."
Anna shook his hand. "I'm Anna"
"Nice to meet you" he said.
Tim smiled and Anna grinned back. "You look really good in that tux" she said.
Tim blushed. "Well, thanks" he said. Anna giggled.
Anna liked him, maybe sh should flirt a little more.
"If you want you can dance with me" she said.
"Oh, sure!" said Tim.
They walked down the hall together.
"Sorry about earlier" said Tim.
"It's Ok" said Anna.
"I'm glad you're ok"
"Me too"
They were approaching the stairs to go down. Tim was leading Anna and she was happy about that. He was a gentleman, and she liked men like that. She liked how strong and confident he looked, and how well he dressed. She liked the way his blue eyes sparkled when he smiled, and she loved the way his smile lit up his whole face.
"Hey, let me buy you a drink" he offered.
"Sure" said Anna.
They went back downstairs and found a table near the dancefloor. They ordered drinks and sat down.
Anna looked around at the people dancing. The music was so loud and clear. She laughed at Tim's jokes and found excuses to touch his hand. Or when she "dropped" her phone let her hand linger on his thigh.
She looked at him and he looked back. He was smiling at her, and she knew he was looking at her chest. It made her feel good, knowing that he wanted to touch her like that. She remembered how he'd looked at her in the bar, and she smiled.
"You've got such a beautiful smile" he said. "Can I kiss you?"
Anna's heart raced. She felt butterflies in her stomach. "Why not" she said.
They walked towards each other. Anna felt shy, but he didn't seem to mind. His lips met hers, and she felt her knees weaken.
They kissed and their hands slowly roamed across each others bodies. Their skin was slick and moist from the sweat from the dancefloor. His tongue danced with her own, and she moaned softly.
Her fingers slid down his pants, opening his zipper and feeling his hardening cock. She squeezed it through his underwear and he moaned.
"I want you" she whispered.
"I'm ready" he answered.
They foundd their way into the cloat room, alone and private. Anna pulled off her dress. Tim unbuttoned his shirt.
"Come here" she said.
He moved closer, and she kissed his neck. He reached down between her legs and rubbed her wet pussy through her panties.
"Do you like this?" he asked.
"I love it" she whispered.
Tim pushed her panties to one side, exposing her soaking wet mound. His fingers slid back and forth along her slit, teasing her clitoris with his fingertips. She moved closer, straddling his waist. He pushed two fingers inside her dripping snatch and began pumping them in and out. She moaned loudly as he finger-fucked her.
"I love your cock" she said. "I want it in my mouth!"
"Tell me what you want" he said.
"I want you to fuck me, please" she begged.
Tim smiled and pulled out his cock.
"Show me how you suck a dick" he said.
Anna wrapped her lips around his shaft, taking the head of his penis into her mouth. She sucked him slowly, letting his cock slide between her lips. She felt his cock throbbing in her throat, and she moaned around it.
"That's so good" he said.
Anna looked up at him, his cock still in her mouth. She looked into his eyes, and she saw lust mixed with desire. She knew he was enjoying it as much as she was.
She moved her head faster and deeper, sucking on his dick. Tim grabbed her head and began moving his hips, fucking her face. His balls slapped against her chin and she moaned around his cock.
Anna opened her mouth wide, trying to take all of his cock inside. She tried to deepthroat him, but he was too big for that. Instead he fucked her face, moaning deeply as the pleasure built up in his cock.
"I'm gonna cum" he said. "Cum with me!"
Anna moaned and wrapped her arms around his waist, pulling him tight against her face. She took his cock deeper and began sucking it harder, wanting every drop. He bucked his hips and shot hot semen into her mouth. She swallowed it greedily, drinking his seed.
He collapsed forward, releasing his grip on her head. He panted and gasped, recovering from his orgasm.
"God, that was amazing" he said.
"Fuck, yes it was" she said, licking her lips.
She looked down at his limp cock, which had already shrunken to its normal size.
"You want another round?" he asked.
"Absolutely!" she replied. if you looked closely you would notice it looked like a small tear came out of her eye. It was all Richard could do, forever a passenger in a slutty goth girl.
