Maybe?

Maximus swiped his access badge at the reader, grumbling under his breath as it failed to read correctly once again. Maybe if he angled it slightly? Nope, still nothing, so...wait, there it was, the glorious beep of access.

Another workday ritual complete, he walked down the hallway towards his cubicle, hoping that Nancy had called off today. Sure, it was slightly flattering for anyone at all to be hitting on an overweight slob like himself, but did she have to be so clumsy and obvious about it?
Also, morbidly obese wasn't his ideal body type - even though he had a probably unhealthy interest in fantasy women whose tits and asses that were bigger than most humans could ever hope to achieve, his fantasies also included bodies much slimmer than Nancy's. Her tendency to wear low-cut tops that displayed massive cleavage were the worst part, since he had caught himself fantasizing about a slim Nancy who somehow hadn't lost any weight in her tits..."Shut up brain, not now!"

But at least the whine of her mobility scooter warned him whenever she had rolled back from her desk across the aisle to stare at him again.

"Max-i-mummmmmm!" hummed the clearly-working-today voice of Nancy, accompanied off-key by the whine of her scooter. "You're looking good today!" Her gaze overtly roved up and down his body before settling at his groin again, and he resisted the urge to check if his fly was open or even glance down to acknowledge her focus. Was his unusually unruly dick still half-hard?

"Hi Nancy", he said in his best fakery of a neutral/cheerful greeting. "Really? I've been trying to lose some weight?" His statement ended in a questioning tone that morphed into quiet squeak of mild horror as he realized his mistake.

Nancy LOVED sharing weight loss tips, and talking about how she lost 5 pounds in a week using this or that plan.
He always **** himself to be supportive, despite his dislike of her, because it would be an asshole move to do otherwise, but...it hurt him every time. So he tried to avoid it.

The most disturbing part wasn't any of this though, but rather that most of his fantasy women had bubbly personalities, were obsessed with fitness to maintain their unbelievable figures, and flirted with him shamelessly, willing to fuck at the slightest suggestion he was interested, which in his fantasies was almost always.

Basically, Nancy minus 300 pounds of weight or so. And maybe some surgery to remove the excess skin?

Maximus suppressed a shudder and made some vague excuse about needing to start work, trying to gently cut off whatever she was saying about a new exercise and meal plan...Wait, that actually might help? Nevermind, time for work.
