"Hello, this is "Mona Pizza", Mona here! What can I do for you? Aha... salami... white mushrooms... salmon... bananas... spinach... a piece from the moon... extra cheese... and a diet cola. Okay, your pizza will be delivered in about 20 minutes. Thank you very much! Bye!"
Mona hung up the phone, taking a casual look at the watch. 'Oh oh!' she thought 'I'll be late for cheerleading!' she was already dressed in her uniform to save time, but even if she drove to the training immediately after the delivery, it would be tough.
She quickly grabbed a piece of pizza dough, kneading it while looking for the ingredients. On the shelves in front of her, packed in little bottles, she saw slices of bananas, spinach, salami, salmon...
The pizza dough tore apart as Mona noticed there was one ingredient missing. "Oh no!" she gasped "I should have known! I should have noticed when he called us, but I was too much in a hurry to listen! I should have known we don't have any - white mushrooms any more as we used up the last ones yesterday."
Panic-stricken, Mona tried to come up with something. Buying some more at the market? No, that would take too much time. Then, an idea crossed her mind: There were other mushrooms in the storage, a fresh delivery from a far away land. 'Maybe one of those tastes like white mushroom.' she hoped, walking over to the storage door.
A chill went down her spine as she entered the gloomy, cold room. Her teeth were shaking, her bare legs shivered as well as her arms. "I-I should have "d-dressed in th-thicker c-c-c-clothes." she murmured. Hugging herself, Mona searched the crates. She finally found one titled "From: Mushroom Kingdom". Still freezing, she opened the box: it was filled with mushrooms of all sizes and colours, many of them having spots, stripes or other kinds of patterns. What all of them had in common were two dots on their stalks which somehow looked like eyes.
Curiously, Mona inspected the fungi until spotting one which woke her attention: It was completely white except for the eyes, looking like it had been painted. She picked it out of the other mushrooms to examine it in her hands. "Maybe this one tastes like white mushroom." she wondered. She knew there was only one way to find out, so she took a bite from it. As she chew the fungus, Mona found it was pretty much tasting like... milk.
Suddenly, a burst went through the teenage girl, sending a warm sensation through her shivering body. She dropped the mushroom, stumbling backwards as she tried to hold onto something. "What's goin...?" She was interrupted by a strange feeling in her chest which suddenly felt like it was blowing up... and as she looked down, Mona saw it actually did! Her modest breasts grew inside her cheerleading uniform, growing an inch by each second. Soon the fabric of her already tight top started to stretch, her breasts having grown into small spheres to big to cover them with her hands.
She grabbed a nearby crate, leaning against it as her bosom tried to drag her to the ground. Her expansion continued, her top sliding up her belly as her breasts had taken all free space. They pressed against her tight uniform, being as big as a CD in diameter, her shirt starting to get transparent around chest. It was painful, even more so as her bra was straining her back. Finally, it snapped off, her breasts once more growing another three inches before ripping up her front.
Mona looked down at her chest. She stared right into the wide depths of her cleavage, going down almost her entire breasts while squeezing her breasts together. As she pulled her broken bra out of her uniform, she was still in a state of shock and surprise, not really realizing what had just happened.
Then, standing inside the storeroom in torn cheerleading clothes with big breasts while holding a bra in her hand, she came back to senses. How will she react?
