"Let's both be elephants!" said Fredrika.
"If you say so," said Emma, "but let's hurry. We don't want to be late for lunch." The two of them undressed and stepped into the elephant suits. They suddenly felt a tingling sensation. When it stopped, their costumes WERE their skin. They looked like typical anthro elephants, but with (very large) human-like hands. They had also gained no additional weight. Fredrika felt her new trunk. She suddenly discovered that it was an erogenous zone. Curious, she stroked it harder and harder. Her spare hand slipped down to her throbbing elephant clit. After a few minutes, she had the biggest orgasm she ever had in her life.
"That... was... fucking... AMAZING!" she finally said after the pleasurable vibrations had died down, "I just wish that I were bigger. I feel silly as an elephant who weighs only 127 pounds. I'm a five foot eight elephant who weighs 127 pounds! A skinny elephant! What's the point of being an elephant if you can't be a porker? Even my boobs are still tiny!" Fredrika had always been insecure about her A cup boobs.
"It does feel weird," said Emma, "Come on, we'll be late for lunch." They threw their clothes back on and ran through the hall to get to the cafeteria. Halfway there, they bumped into someone.
The stranger was an elephant girl like them. But she was so huge. Massive rolls of fat covered a layer of solid muscle. "Hi, are you the new transfur students?" she asked, shaking trunks with Fredrika. It felt pretty sexy.
"Yeah, we're the transfur kids," said Fredrika, "sorry we bumped into you."
"It's okay," said the elephant girl, "My name's Becky. What are yours?"
"She's Fredrika and I'm Emma," said Emma.
"Pleased to meet you," said Becky, "Wow! You're really skinny for elephants."
"Yeah," said Fredrika, "It's horrible! We want to be fat like you!"
"Well, let's get to work then," said Becky, "We'll start at the gym." Becky then whisked Emma and Fredrika to the gym and set them to work weightlifting and running on the treadmill. By the time Emma and Fredrika were done, they had muscles to rival Arnold Schwarzenegger. Emma was a little surprised that she gained so much muscle mass from just one day of working out, but then she remembered that she was a cartoon character. Becky then took them to the cafeteria to FINALLY get their lunch. They loaded up on pizzas, burgers, fries, pork rinds, and sodas. They then topped it off with ten sundaes each. By the last bite, their bulging muscles were covered in a thick layer of blubber. Fredrika finally had the HH cup boobs she always wanted.
"We look awesome!" said Fredrika.
"But you need new clothes," said Becky, "You two are naked." It was true. Emma and Fredrika's clothes had been shredded by their new girth. "Let's go shopping. The school won't mind." The three girls hit the mall. they bought miniskirts and tube tops to show off their blubber. After they had everything they needed, they headed back to the school.
"Thanks for bulking us up," said Fredrika, "How can we ever thank you enough?"
"Just be my best pals," said Becky.
"Okay!" said Fredrika and Emma.
