Amber ran and made it to class a few seconds ahead of the bell. "Please be seated, students." Ms. Crow, her biology teacher, was a perfect example of how to age gracefully. She was nearly 70, but she was humorous, lively, and kind. "Today we're going to start on the digestive system. Now, who knows what the definition of a calorie is?" Amber rose her hand. "Yes, Amber?" "A calorie is the amount of energy required to heat one ounce of water one degree." "Correct," Ms. Crow said as she wrote that down on the over head. "What most of you probably don't know is that the calories you girls worry about on the side of packaging are actually kilo-calories, or 1000 calories." She wrote C=1000c under the first definition. "Do you know how to determine how many calories are in a piece of food. No one raised a hand. "Well, one way is to burn them. So, for today, we'll be performing a lab to determine the caloric energy of a peanut." Ms. Crow pulled out a jar of peanuts. "Everyone get a beaker stand, some foil, a cork, a toothpick, and a few nuts. Use the foil in the circular holder of the stand to make a bowl. Fill it with PRECISELY 10 ounces of water." Everyone scrambled to the sink to do this. "After you've done that, stick the toothpick into the cork and spear the nut onto it. Use a match to light the nut on fire, but be careful! Make sure you remove the match quickly to avoid spoiling the results." Amber loved doing these labs in bio. She got the nut burning after a few tries, and let it heat the water.
However, as Amber leaned on the desk, watching the flame flicker, she felt the tingle from before come back. It was focused in her chest area only, though. She looked around. Everyone was focused on their peanuts like her. So, as discreetly as possible, she rubbed her chest to try and relieve the sensation. Instead, she felt to small, fleshy lumps. A chill ran down her spine. She looked down. Her shirt was a bit baggy, so she couldn't tell, but she thought she'd felt...she tried to ignore it, but the tingling got worse. She touched her chest again, and they were there again, even larger than before. She put her jacket on zipped it up to her neck. "Ms. Crow, may I use the restroom?", she asked, trying to keep her voice level. "Sure, but hurry, and get someone to watch your nut." Amber got a guy she sat near to to watch it and his own. She thought it was weird how guys were so happy to help her, but not some of the other girls around school. She slowly walked out the classroom, but once out of sight, she ran to the bathroom.
Amber locked herself in the handicapped restroom and removed her jacket and top. Bracing herself, she looked down. Greeting her were...breasts. Decent sized ones. They were about as large as good-sized apples, and just filled her hands. She cupped them, feeling them, to make sure they were real. They were if the pleasure she was feeling from them was anything to judge by. As she held them, the tingling returned. Even as she watched them, they grew! They slowly swelled out until they were almost overflowing her hands. She finally broke her shock. What the hell! Where did these come from? Why am I growing? She thought back to lunch, about what she might have eaten. Thinking about that made her remember their conversation. The expansion virus...it might be in the city...Megan might be infected...her wound, covered in Megan's saliva...oh God. Horror overwhelmed her. She was infected! She cupped her breasts and tried to force them down, as if that would make them go away. Instead, they defied her and grew again, up to halved cantaloupes. She wanted to sink down and cry, but her resolve, and her location, made her stop. She whipped out her phone and texted Tiffany. It was her free period, so she probably wandering around school, waiting for the bus to come. TFF NEED HLP SOS D WING RR HURY DNT SCRM. Tiffany responded quickly by texting K OMW. Amber struggled to get her shirt back on. It fit, though tightly. She heard the door open and close. "Amber, you here?" "Yeah, I'm in the stall." "What'd you do, fall in?" "No! Just...stay calm, okay?" "Okay, hit me." Amber took a deep breath and opened the stall door. Tiffany stared at her for a moment, went up and down her body, then froze when she focused on her breasts. "What..in..the..fuck?" "I...think Megan is infected. I punched her, but I cut myself on her teeth...her spit got in my cut..and now..." She gestured at her bust. "Wow...you punched Megan! Oh yeah, that's more like it, girl!" Tiffany raised her hand to high-five. "I've got a bit of a problem, here, Tiff." "Oh, right, the boobs. Well, you can't go out like this, not with everyone around. We'll have to cut the rest of the period to get you out of here unseen." "But, I've never cut before!" "Then now you have an excuse. Let's go, and put your jacket on."
Tiffany checked out to see that the coast was clear, then lead the way to the parking lot. "We'll hide out in the store up the street. Then, after school let's out, we can get Amanda to pick us up." "We could leave now if you'd passed your driving test." "Hey, I forgot that you can't drive in a bike lane. I didn't hurt anyone...seriously." Amber rolled her eyes. "Kay, Ricky's going around the corner. Let's move." They ran quickly, but Amber was slightly slowed by her bouncing, heavy new assets. She felt the tingling again as they rounded a corner onto the main street. "Oh no, I'm...growing again." Tiffany turned to look at her. Her shirt was stretched even more as her boobs grew larger. This was a bog one, and her boobs doubled in size. She looked like she was smuggling a pair of cantaloupes in her shirt, which was ripping along the sides. "Damn, girl, you make Megan look tiny." "I don't care about that right now. Let's just hurry, my shirt can't take another growth spurt."
