“Hey dad, did you ever try wearing clothes from a store and seeing how they change your body?” Jon asked.
“Well, not really. I had never thought of that. I always just tried on clothes my size which wouldn’t have any effect on my body,” his dad said. “You should try it out sometime.”
“Yeah, if it works I can customize my body however I want, and I can help you guys customize yours too,” Jon said.
“Well let’s not get too carried away,” his dad said.
Later that day Zoe got home from her run, and Jon and her switched their lower halves back to normal.
“Hey Zoe, can you drive me to the mall? I had an idea about how to use my power. I want to try wearing store bought clothes and seeing how they change my body. If I can customize any part, then I can swap them onto you or anyone else that wants a custom body part,” Jon said.
“Woah! Do you think that would work? I would love to have a bigger pair of boobs from time to time,” Zoe said.
“Well there’s only one way to find out,” said Jon.
“Okay, I’ll drive you to the mall.”
Jon and Zoe got in the car and drove to the mall. Their first stop was the clothing section of the department store.
“Okay, so let’s see what happens if I try on something that isn’t my size,” Jon said as he picked up a big pair of shoes and went into a deserted corner of the store with Zoe. He slid the big shoes on, and all of a sudden he felt his feet grow and fill up the empty space in the shoes.
“Zoe, I can feel my feet growing!” He pulled off the shoes to look at his bigger feet.
“Wow, it works just like you thought it would! That’s so exciting. Try putting your own shoes back on,” Zoe said.
“Okay,” Jon said as he slipped on his regular pair of shoes. He stuffed his enlarged feet into them, and they shrunk back down to his normal size.
“Great, let’s try something more ambitious now,” Zoe said holding up a bra with pretty big cups.
“Zoe, we’re in public. I don’t think I can just try on a bra casually,” Jon said.
“Relax, let’s just go into the changing room. You can swap the big boobs onto me as soon as they grow,” Zoe said.
“Fine, as long as no one sees me with a huge pair of boobs,” Jon said. He was a bit more excited than he let on to try on a big pair of boobs. He’d enjoyed holding onto his mom’s for the night, and he’d been wanting to try a bigger pair.
“No one will, trust me.”
Zoe and Jon walked into the changing room, and luckily no one was around as they walked in together. Jon took off his shirt and Zoe handed him the bra.
“Geez Zoe, an F Cup, these things are gonna be huge.”
“I know, that’s the fun part. I just want to try them on occasionally,” Zoe said.
Jon put the bra over his chest and strapped it on. He watched as his chest expanded to fill the big cups, leaving him with a big pair of F Cup tits supported by the bra.
“Oh my god. That was amazing. You look incredible Jon,” Zoe said.
“These things look huge from my perspective. They’re twice the size of mom’s!” Jon said as he poked one of them, causing his boobs to jiggle. He kind of liked the feeling of having the two weights on his chest.
“Okay, now for the swapping,” Zoe said. She took off her shirt and then unstrapped her bra, causing her modest B Cups to fall and hang free. Jon felt up his big boobs one last time before unstrapping his bra, and watching his tits fall. Zoe handed Jon her bra. He started to try to put it on.
“Zoe, this is really tight. I’m trying to wear a B cup bra on F cup boobs,” he said.
“I can help you strap it from the back, Zoe said. She went behind Jon and forced the bra on. All of a sudden she felt a tingling in her chest as her boobs began to grow, and Jon’s began to shrink. Hers grew all the way up to an F cup, and Jon’s went down to a B.
“Oh my god, it worked Jon. I have a big pair of boobs!” Zoe exclaimed.
“Yeah, this has a lot of potential,” Jon said looking down at his smaller breasts. He looked over at Zoe admiring her new boobs in a bit of jealousy. He kind of liked having the big boobs.
“Alright, anything else you want to try bro?” Zoe asked.
