Prompt: Feeder demoness possesses a fitness coach and instead of slimming down her clients leads a trail of bloated fitness failures in her wake.

   A typical Tuesday evening at the gym usually involved Trianna doing her job as a coach to motivate others to strive for their idealized body. However, the past few months had seen her work out routine go through a drastic makeover. The exercise equipment had been put aside in favor of soft chairs and tv screens. Healthy snacks and water bottles had been swapped out for bottles of soda and enormous hordes of junk food. While it was obvious that something was wrong, Trianna’s clients couldn’t help returning each week in spite of their worsening conditions.

   Making her rounds through the room, Trianna made sure to encourage her students to keep up their slothful behaviors. Stopping by the television screen, she took strange pleasure in picking crumbs out from between the sagging pecs of a man who could once sprint a mile without breaking a sweat. Meandering over to the snack area, she was more than happy to help a pair of women open up a soda bottle to satiate the thirst of their beer keg-like bellies. Giving a husband and wife couple meaty slaps to their chunky rears, Trianna excused herself from the hedonistic event for a trip to the bathroom.

   Stepping before the mirror, Trianna momentarily dropped her disguise. Crimson red covered her skin, reaching from the base of her spaded tail to the pair of pointed horns on top of her head. Grabbing hold of her muffintop, she could feel her demonic powers swell from the overwhelming indulgence of her clients. Feeling her belly bump up with another layer of flab, the demoness inhabiting the fitness instructor’s body reveled in the fact that soon all of humanity would become an endless supply for her gluttonous powers.
