Bernadette wobbles up the stairs to Penny's apartment, having gotten a lot of stares on the way. People were just as in awe with her humongous tits as she first was.
"Getting used to these melons is going to take a while, they bounce around like they've got a mind of their own" She thought.
She arrived on Penny's floor dressed in a yellow dress with a simple plain cardigan, she no longer had any bras that fit so for now she was going without. She reached Penny's apartment and knocked on the door.
"I wonder how she will react?" She thought. Just then the door opened, and Penny appeared. Out of the girls in her friendship group, Penny was easily the hottest. Her tall frame matched with her slim figure meant she stood out more, and her nice round ass would stick out from her body, easily catching the eyes of most passers-by. It was only up close that the men would notice Bernadette, though that might change now. Penny was wearing skin tight jeans which hugged her big ass nicely, up top she was wearing a simple red top with short sleeves, which only covered her shoulders. Penny had big tits compared to most, but even before the drug Bernadette had her beat.
"Hey, I was beginning to wonder where you... WHAT THE FUCK!!" Penny shouted, her words and eyes giving away that she had noticed Bernadette's new change.
"What happened? Did you get a boob job?" She asked.
"Can I come in? I'll explain it, but just not in the hall." Bernadette replied. Penny moved over, never once taking her eyes of Bernadette's massive melons. She closed the door and followed Bernadette to the couch.
Bernadette sat down on the couch and removed her cardigan. She could hear Penny gasp next to her. When she was ready she turned to look at Penny.
"Right, first I haven't had a boob job. This only happened last night and the only reason for it is this." She said calmly while placing a small container on the coffee table.
"What is that?" Penny asked. Her voice starting to sound normal again.
"It's a new drug I've been working on at the lab. It was only supposed to make the recipient appear younger and make them more attractive, but obviously something went wrong." Bernadette explained.
"Well why did you take it, Leonard told me you guys have to do tests on it first or something?" Penny replied. She couldn't help but start to feel a tang of jealousy at her friend's impressive assets. Penny knew that Bernadette had bigger tits to begin with, but this took the biscuit. She looked down at her own tits, not huge but still bigger than most.
"Well the company wouldn't allow human testing but, I was positive it would work, so I may have smuggled it out of the lab and took it at home." Bernadette said.
"What did Howard say?" Penny asked.
"Well he reacted just like you did at first, then he remembered that he accidently took it as well." Penny reacted to this just like she did earlier.
"WHAT... Well what happened to him." She replied. Bernadette just took her hands and then held them about five inches apart, then she started to move them further apart. Penny watched in awe as her friend's hands went from five to six to eight to finally stopping at ten inches apart. She unconsciously licked her lips at the thought of such a large cock.
"I don't know what to say." She said
"Me neither, it's a lot to process I know." Bernadette replied. Both girls just staring at each other.
After several moments had passed, Penny's eyes wandered from Bernadette's eyes, to her buxom chest, to the small container sitting on the coffee table.
"I wonder if it would do the same for me" she thought.
"If I had tits even half Bernadette's size, then I would be a walking wet dream. Tits, ass, slim waist and blonde." Penny thought. She started getting hot just thinking about it.
Just then, Bernadette stood up and started walking round the couch.
"I need to use the bathroom, won't be long". She said. Penny watched as Bernadette crossed the room and made her way to her bedroom. Once she heard the click of the bathroom door she raced in to action. Grabbing the small container off the coffee table, she headed for the kitchen. She got a glass from the cupboard and quickly filled it with water. Turning around to the kitchen island and taking a pill from the container.
"I hope this works". She said to herself. Closing her eyes, she quickly took the pill and placed it in her mouth, before taking a sip of water to wash it down.
She stood there for several moments in anticipation of what would happen. After a while nothing did, she began to wonder if Bernadette was telling the truth. Just as she thought that Bernadette returned. She walked to the kitchen and saw the glass of half-drunk water and the open container.
"Did you take the drug?" She asked, the concern evident in her voice.
"Yeah, I want to have bigger tits too, imagine it me and you walking round town with huge racks, turning heads where ever we go." Penny said.
Bernadette pictured it, she had never been popular growing up, her big tits were the only thing she liked about herself, as she felt she had something over the popular girls. She imagined her and Penny in a club, getting free drinks from all the guys trying to seduce them, but only to leave them hanging as she returned home to get fucked hard by her hung husband.
"It would be pretty fun actually". She said
"Exactly, how long did it take for them puppies to grow." Penny asked.
"I don't know exactly, I took the drug before going to bed and woke up with them". She replied.
Penny moved round the island and headed for the couch, Bernadette followed.
"My jeans feel tighter than before, and they were already tight." Penny said as she stood in the middle of the living room.
"OH MY GOD PENNY, YOUR ASS IT'S, IT'S GROWING." Bernadette shouted. Penny could feel her ass expanding and her jeans start to tear. She ran to the bathroom and stood in front of the mirror. She watched as her ass grew, going from big to huge and round.
Bernadette appeared at the door and watched. She could just see Penny's lace underwear through the tears of her jeans, although with her new ass it looked more like a thong.
"OH MY GOD, MY ASS IT'S HUGE." Penny shouted. She reached round to touch it and it felt so big and juicy, she removed her hands and watched it jiggle.
She was in shock, as was Bernadette who had now just noticed Penny's thighs as well which looked muscular and toned.
"I supposed they had to be to support that ass" she thought. Penny turned to Bernadette.
"Are you okay? How do you feel?" Bernadette asked.
"Fine, like nothing happened." Penny replied.
"You're not upset then." She asked, Slightly hesitant at her response.
"Are you kidding me, look at this ass, I've never felt better. It's huge". Penny said excitedly. She walked passed Bernadette and back into her bedroom. She went to a draw and took out some new jeans. Penny then took off what remained off her ripped up jeans and removed her underwear, before then putting on the formally loose fitting new jeans which now hugged her ass nicely. Turning to Bernadette she said.
"Come on, I've got an idea." She then headed off to the kitchen.
Bernadette watched her friend move, her ass swaying hypnotically from side to side as she went. Once she reached the kitchen, she saw Penny taking the small container and head for the front door.
