Massive, Unhealthy, & Still Gaining

Ivy Davenport has gotten so obese that she's losing her mobility. She now uses a scooter to get around when she has to walk more than 100 feet or so. She spends all of her time sitting, no longer able to stand for more than a few minutes at a time without getting winded or feeling like she's going to collapse. She barely ever moves. Her breathing has become labored and she has to take medications for various obesity-related health problems. And yet, she still finds herself wanting more. Pushing forward with her gaining, no matter what the cost.
