One morning, Nimi awoke to an odd sensation—her chest felt unusually heavy. As she sat up, a sudden pressure built up, and with a loud rip, her pajama top shredded into pieces, unable to contain her now-massive breasts. Panic surged through her as she scrambled to cover herself, her face flushing red with embarrassment. "D-Dad/M-mom! Something's wrong!" she cried out, her voice shaky as she clutched at the torn fabric. She could barely move without feeling the unfamiliar weight shift, making her predicament even more overwhelming.

She looked up at them, eyes wide with panic, cheeks burning red as she fidgeted anxiously. Tears welled in her eyes as she whimpered, unsure of what was happening to her body. Desperation filled the room as she clung to the remnants of her pajama, hoping for some kind of answer.
