Trisha felt her slight bump and thought of the twins growing inside which used to be mother and son.
As she carefully ran her hand along her stomach the bell at the door of the store rang as a customer walked in.
"How may I help you," said Trish as she eyed the 19-year-old girl who walked into the store.
"Oh, hi, I'm just having a look, it's a pretty weird store you've got here," the girl said.
"That's for sure," Trish said.
The pregnant store clerk had a sudden idea... she couldn't do that, she thought to herself.
"My name's Trish, I could be wrong but I think I've got something that could interest you," she said to the girl.
"Oh really? What is it," said the girl. "My name is Julie by the way."
Trish guided Julie through to the menswear section of the store. "Uh, why are we here, it's all guys clothes," said Julie.
"Well I thought an attractive girl like you would have to have a boyfriend," said Trish. "Why don't we pick something out for him."
"Oh, okay," said Julie, not quite sure what the girl was on about.
Trish and Julie wondered through the store looking at various clothes, all the while Trish kept checking out Julie as she started to change.
Julie hadn't noticed yet but she already had slightly broader shoulders and her shoulder-length blonde hair was now only just past her ears. Her butt was tighter and less rounded and her whole body had more defined muscle on it than before.
"Wow this jacket looks nice," Julie said and then held up a hand to her throat.
"What the... why does my voice sound so husky."
"Welcome to our store," Trish said. "I need a daddy for my twins here and I thought you'd be the perfect specimen."
"What are you on about lady," Julie said. Her voice was definitely much deeper now and her whole physique was very manly.
Suddenly Julie gasped as she saw herself in a mirror. "What in the hell," she said.
She ran her hands along her arms, her forearms were wiry and hairy and then she felt the bump of her bicep, much bigger than it had ever been.
"This is crazy," the quickly changing teenage girl said.
Slowly Julie's boobs lost their definition, they sank into her body as her chest barrelled into a rock hard set of pecs that strained her tank top.
"Jesus christ," the now almost-male Julie said.
She felt her abs expand and bulge under the tank top as she struggled to rip it off. She tore the top off and stared as her bra struggled to stay in one piece.
She was pretty much male from the waist up, her chest narrowing from her broad shoulders to a taught waist in a sexy v.
Her face rippled and she felt a pinch as her soft feminine face transformed into a chiselled male one, with a defined jaw and smouldering eyes.
"Oh my god," Julie said as she felt something happen below...
