"So Ash, are you excited for the big party?" asked Serena
"I sure am" replied Ash "After getting my 5th gym badge, I need to relax before training again. This big party at that mansion sounds amazing!"
Ash and Serena, after parting ways with Bonnie and Clemont for the weekend, had recieved an invitation for someone's party. Ash believed it was meant to celebrate something important and seeing how he was getting a reputation for being a very smart person (not), he was happy to be invited. The invitation also said to bring someone along so Ash had to think about this. Bonnie was too young to be going to a party, which left Clemont and Serena. Clemont was very interested in stopping Bonnie from getting Clemont a girlfriend or someone to look after him. Serena was a Pokemon performer and loved to explore the region with Ash. When Ash made his decision and chose Serena to come along, Clemont didn't mind at all. He couldn't risk leaving Bonnie on her own for the weekend. So when he heard Ash chose Serena, he sighed in relief Bonnie wouldn't be up to mischief whilst he was gone.
"Do you think we should get some fancy clothes?" asked Ash "I'll just be wearing my casual outfit like always"
"Well if you want to wear what you are wearing now that's fine" replied Serena "I, however will be wearing something fancy for the party"
"Ok" said Ash "There is a big shopping centre half a mile from our campsite. If you go there now and get your clothes I'll be all ready at the campsite for the party."
"On it" smiled Serena as she was hoping to impress Ash again "I'll see you later" Serena smiled as she walked off in a different direction to head to the shpping centre whilst Ash headed to the campsite.
6 Hours Later
"Alright all done" said Ash to himself "I hear someone who could it be?"
"Hi Ash" smiled Serena as she walked into the tent "Do you mind getting out so I can put my dress on?"
"Sure" shrugeed Ash and hoped that the dress Serena chose was good.
10 minutes Later
"All done" yelled Serena "Ready to see?"
"Sure am" smiled Ash as Serena came out of the tent.
"Holy" yelled Ash "You look amazing Serena!"
"Thanks Ash" blushed Serena as she was happy to hear a compliment about what Ash said "Now lets go to the mansion to party!"
Meanwhile, outside the tent whilst Ash and Serena were discussing plans for the party, Team Rocket were listening very closely.
"So the twerp and twerpette are going to a party? How come we weren't invited!" yelled Jessie.
"Maybe because we are known now for stealing Pokemon for money!" replied James
"Still I'm up for crashing the party! Let's make this party burn in chaos and steal all the Pokemon!" yelled Meowth
"I'm in" nodded James
"Let's go Team Rocket and let's steal, I mean catch some Pokemon!" yelled Jessie with an evil grin.
Now after arriving at the party Ash and Serena were looking for the man they needed too. Just then, the man they needed came out of nowhere.
"Ah Ash glad you made it" he smiled.
"Thanks Mr....." questioned Ash.
"No worries young man. My name is Mr Junmore but you can call me whatever you please. " replied Mr Junmore "Now" looking at Serena "Is this your plus one?"
"Yes" replied Ash with a smile that made Serena blush "Her name is Serena"
"Great Scott, I remember seeing you in one of those Pokemon performance contests." yelled Mr Junmore with delight "Now that I see you in person, your much prettier than I expected."
"Thanks" blushed Serena
"Well then go have some fun" smiled Mr Junmore
"Thanks sir" smiled Ash "Oh and happy birthday!"
2 Hours later and the party was in full effect. Everyone was either chatting, playing pool, flirting or just having fun. Serena, although not nervous, chose to stay with Ash in case anything went wrong. Ash was happy about this and spent a lot of the time battling trainers. He enjoyed this very much and wanted to do this all night. Just then, Ash started feeling an urge to go to the bathroom. The problem was there were no bathrooms in the mansion so he had to make a quick excuse to leave and tell Serena to stay with Mr Junmore.
"Um Mr Junmore, I need to be going somewhere tomorrow so I need a lot of sleep" asked Ash "Can I leave?"
"Sure young man happy that you enjoyed the party" smiled Mr Junmore
"I did it was a lot of fun." smiled Ash then went to Serena and said "Stay here, I'm just going to go to the bathroom so stay near Mr Junmore ok?"
"Sure Ash" smiled Serena as Ash walked off into the night.
Unfortunately for Ash, Team Rocket, along with a Gothitelle and Gardevoir, saw him and set off to follow him.
20 minutes Later
"Aaaaaaaaaaaaah that's better" sighed Ash as he finished his bathroom break. He was heading off back to the mansion when he was forced into mid-air by Pokemon.
"What is this?" yelled Ash as he saw a Gothitelle and Gardevoir using Physic on him to keep him in mid air
"Well well well Twerp" smiled a familiar voice and Ash turned to see Team Rocket smiling
"Let me go" yelled Ash "I have no Pokemon, I haven't done anything just let me go!"
"Well sorry to say this young man but we have plans for you" smiled James "Gothitelle and Gardevoir, this person we just caught is not really a boy. He is a girl. Do you understand that?"
"Gardevoir" said Gardevoir
"Gothitelle" said Gothitelle
"They said they understand and can complete transformation right away" translated Meowth
"What I'm not a girl" yelled Ash but no help came and the transformation was under way.
Ash's spiky hair flattened a bit and grew to extreme lengths, growing up to his stomach. His eyes became larger, his eyebrows became perfectly trimmed, his cheeks became rounder, his mouth widened to give him a cute look. His feet shrunk quite a bit whilst his hands became smaller and more dainty.
Ash then felt his body being too big for his clothes as his shirt shortened to make him hard to walk. All body hair retraced back into his body, leaving smooth silky skin. His waist sank in, his hips flared and his rear end began to stick outwards more now, making any boy proud of.
"Stop it" yelled Ash in a high-pitched voice but nothing came. His manhood slipped inwards and was replaced by womanhood. His nipples became to puff up and swell outwards forming breast tissue and growing till it reached a BB Cup, quite large for a girl Ash's age. Her trousers rolled upwards and split in two, one half replacing his black pants with white panties that hugged her larger butt and vagina. The other half formed a mixture of a skirt and shorts. A bra snapped onto her back, making it easier to walk around now. With the transformation done, Team Rocket laughed.
"Now time for dress up party" yelled Jessie and James as Gothitelle and Gardevoir replaced Ash's normal clothes with a beautiful green elegant party gown.
"Right now that that is done, let's go back to the party Ashley" smiled Meowth "Only we can control what you do!"
"As you say" muttered Ashley in a high pithced voice
Once they arrived at the party, Team Rocket and their befriended Physic Pokemon hid in a bush and started to control Ashley's movement.
"Madam, no need to barge into me like that" said one man
"Sorry, but you need to be aware it's hard for woman to walk around and have fun" forcefully said Ashley
"Oh well yes. Never mind, carry on!" replied the man
Soon Ashley came across Serena, who had been practising Pokemon skills with her Pokemon. She looked up and noticed Ash, or someone that resembled Ash.
"Um whatever your name is, who are you?" questioned Serena
"Ashley" replied Ash reluctantly
"Oh ok. I was wondering since my friend Ash left here and never came back" replied SerenaHELP ME BREAK FREE, thought Ash but instead came out
"Don't worry about him, boys can handle themselves.
"Ok. Since you look like a good Pokemon trainer, can we battle?" asked Serena
"Sure" replied Ashley and the old memories of Ash were gone forever now.
