After a fiasco involving some weight gaining nutrient bars created by Robotnik, Tails, with a little help from Fiona, decided to take on a small side project and try and neutralize the weight gaining formula used to make mobians pack on pounds at rapid fire pace. Hopefully, afterwards the bars could be used as a "super quick" weight loss supplement to help others with their exercise and dietary routines. Once the first batch was done, it was time for a test run. Not wanting to feel like she was doing too much work, Tails volunteered to try out one of the new and improved bars. But Fiona was insistent on helping the little guy she wanted to make amends with, and tested it with him.

Things seemed calm at first, until with a sudden and audible "BWOOMPH!", the two foxes had suddenly ballooned to twice their regular weight. And at an almost instantaneous pace too! Fiona was surprised to find that her waistline had been obliterated in just mere seconds, but one look at Tails' guilty face was enough to keep her temper at bay. She knew the little genius didn't mean it, and he probably felt a bit upset and ashamed that his experiment didn't work, and ruined her figure in the process...

So he was surprised and a bit relived when Fiona snatched him in his arms and pulled him into a big (and admittedly soft and cozy feeling) hug. No matter what, Fiona was going to be sure Tails had all the encouragement and support he could get. And if it means having to spend a few days as a plus sized vixen, then who was she to complain? Besides, she knew she could make it work for her. Tails smiled and chuckled as he hugged his friend back in response. And afterwards, he'd even treat her to a chili dog lunch just so they can take some time off from working in the workshop. Usually Fiona wasn't much of a Chili Dog person. But with a figure as massive as hers... well, she certainly wouldn't mind indulging herself for a little while!

So for some context: These are the last two panels of a Fiona and Tails transformation sequence my friend and I did for LenaLePutt. Well, I just loved the last two panels so much, that I wanted to isolate them and make them into their own thing separate from the sequence. The Weight Gain bars and Tails and Fiona's relationship here were inspired from Fanartist2020's works. So I only felt it'd be fair to have a fun and wholesome moment between the two, set in their universe and without any TF context to it. That said, I hope ya'll like it regardless.
