A Typical Friday?

Today was a pretty long day at school. I started the day by arriving late, because I stayed up too long last night scrolling endlessly on my smartphone in bed. Then, I realized I forgot my homework at home in my morning panic. Add to that the fact that today's a Friday and that all my least favorite classes ended up being packed on Fridays, and I have the perfect cocktail of a catastrophic day in high school. Thankfully, there's a silver lining to this story, the upcoming weekend. As I started stuffing my stuff in my backpack, I spotted from the corner of my eye someone approaching and waving at me. "Heya, Ren Maxwell Conners! Having a rough day? It's pretty rare to see you get to school late like this morning," a familiar voice said. The person in question was Galko, my childhood friend, who happened to be both in the same class as me as well as the most popular girl in school. I understood why without any problems; she was super nice, super friendly, super kind, and her body was out of this world. I'd always wondered why she decided to get the whole gyaru look, since she was the exact opposite of what I assumed most gyarus to be. She didn't gossip, she didn't like talking about lewd things, and she had never been in a relationship. Hell, she hadn't even shown interest in any boy for as long as I'd known her! Galko didn't wait for my answer and left right away. She even seemed somewhat embarrassed, strangely enough. Being a dense young boy, I wasn't really sure what was up with that, but I decided to comply nonetheless. A few minutes later, I joined up with her where she asked me to meet her. As I entered the storage room, Galko turned to me with a nervous expression. "Ah! You came! Thank you so much, I wasn't sure you'd really come and I really, really have something important to tell you today and I don't want to mess it up," she said, talking very fast and seemingly stressed by what she had to say. My heart started beating a little faster as I realized that this wasn't just a casual meetup. Galko took a deep breath, and I could see the nervousness in her eyes. She was about to confess something, but before she could say a word, she suddenly gripped her head and chest, looking like she was in pain. "Badum... Badum... Badum, Badum, Badum!!" I could hear her heart beating like a drum in her head as she stumbled back slightly, breathing heavily. Her eyes widened in surprise, and she gripped onto a locker as her legs felt wobbly. She let out a moan of pleasure, and I could hear the sound of fabric stretching tight as well as gurgling and bubbling from her stomach and breast. That's when things started to get really weird. Galko's body began to grow, and I mean really grow. Her breast grew from a modest C cup to a D cup, then to a double D cup. The buttons of her shirt popped open, and her clothes started to tear as she grew larger and larger. I was shocked and unsure of what to do as Galko's body continued to grow, her face contorting in a mix of pain and pleasure. In a matter of seconds, she had grown from 5'6" to 7 feet tall, and she was still growing. Her back was now pressing hard against the ceiling of the storage room, and she had to crouch down just to fit in the room. I was frozen in place, unsure of how to react as Galko looked around frantically, wondering why this was happening to her. She glanced at me, her eyes pleading for help, but I was just as clueless as she was. There was no way to stop this, and I could see the fear and panic rising in her eyes. "Please, Ren, you have to leave," she said, her voice shaking. "It's not safe for you here." But I refused to leave her alone. I held onto her growing body, my hand barely fitting around one of her thick fingers. She looked down at me, teary-eyed, touched by my courage and compassion. "Ren, please," she whispered. "For your own safety, you have to go." But it was too late. With one final surge of growth, Galko's body burst through the ceiling of the storage room, demolishing the drywall and wooden beams. She let out a deep, loud moan as she arced back, her breast pointing skyward, before falling back over with an earth-shattering thud. The room was in shambles, and I was covered in dust and debris. As I stumbled backward, I watched in awe as Galko's giant body lay on the ground, her chest heaving with exhaustion. She was enormous, at least 8 meters tall, and completely naked. I couldn't believe what I was seeing. What was happening to my friend? And what would happen to us now?
