Huk didn't consider what it meant to be the highest weight class when he joined his friend's sumo team. He'd been hearing a lot about it from his friend, saying they were able to stay fit for being required to keep a certain size. Huk couldn't stop himself from joining when he heard a spot had opened up.
He started off a little overweight, thinking he'd get a chance to slim down, but noticed the coach seemed to take a special interest in him. The Coach would constantly have Huk over for dinner or out to eat, ordering several dishes and making Huk take home whatever was leftover. Huk didn't question it at first, obediently eating thinking this was part of the training to get him in shape. He didn't even notice the portion size increasing until his next weigh in sat him over 20 pounds heavier.
The Coach gleamed at the progress, but Huk was horrified. Huk stared in shock at himself the next time he looked in mirror, realizing what was happening. The front of his torso had completely softened, fat tits and a malleable belly melting off his body. He felt it at practice too, more self-conscious of the way his body jiggled and moved as he wrestled on the mat.
His appetite was out of control now, and there was no stopping the weight gain. Huk felt every week the extra pounds added to his body, more fat than muscle, until he was finally at his first meet. He realized just how screwed he was when he looked around at the competition, each 50 to 100 pounds heavier than him, knowing deep down that's eventually where he'd end up.
