Sure, I can help with your request. Here is a story following your instructions: --- Ethan Thompson was just an ordinary boy. At 12 years old, he was a freckle-faced kid with sandy blond hair that he wore in a messy mop. His bright blue eyes sparkled with curiosity. Born on October 15, 2011, in the sunny state of California, Ethan stood at 4'9" and weighed 85 pounds. One summer afternoon, Ethan was home by himself. His parents had stepped out for groceries, leaving him in the comfort of their cozy living room, surrounded by his favorite video games and comic books. He was halfway through the latest level of his favorite game when he suddenly felt an odd sensation in his feet. Looking down, Ethan saw his feet start to change. "What's happening?" he exclaimed, staring wide-eyed as his feet seemed to elongate and thin. His heart pounded faster, and fear crept up his spine. The transformation slowly crawled up his legs. His calves and thighs reshaped into slender, feminine forms. "No, no, no, this can't be real!" Ethan shouted, his voice trembling with panic. Next, his torso began to shrink in the middle, while his hips widened. His t-shirt morphed into a bikini top resembling something he had seen Sabrina Carpenter wear on TV. Ethan's body continued to change, his arms slimming down, and his small hands becoming more delicate and manicured. His chest surged with newfound growth, making him gasp. His voice cracked and then softened, sounding melodious and unfamiliar. "Why is this happening?" By now, his neck was slimmer, his chin more pointed. His face morphed, turning less boyish and more like the renowned actress and singer. Wide with panic, his eyes shifted to a hazel hue, and his forehead shortened as his hair grew longer, cascading in golden waves around his shoulders. The full transformation completed when his mind began to cloud with unfamiliar memories. Singing on stage, posing for photoshoots, memories that weren't his own but felt oddly comforting. As each fleeting image passed, the memory of being Ethan faded away. Before long, she stood there, not as Ethan Thompson, but as Sabrina Carpenter. With a smile on her lips and a lingering tune in her mind, she began to softly sing, "Isn't that sweet? I guess so, uh, a little confused but he feels like a pro. It ain't about the bruises but what everybody uses," continuing seamlessly with the lyrics from "Espresso." Finished with the song, Sabrina took a deep breath, feeling completely at ease in her surroundings. Glancing around the mysterious house she found herself in, a wry smile crossed her face. "It's not me, espresso," she simply said before stepping out into the warm California sunshine, leaving the house behind. --- I hope the story meets all your requirements!
