Hanzo knew about how Cassidy liked to fill his stomach, make it bloat out until it looked engorged. However Cassidy didn’t know that Hanzo loved watching him as he did so.
Hanzo took to admiring from afar, watching Cassidy sit at the table in the communal kitchen, clutching his belly after stuffing himself full of leftovers. His stomach gurgled and sloshed, full of excess food. All the excess food was adding a bit of chub onto Cassidy’s form. Hanzo could see the outline of his stomach pressing against his previously loose shirt, after a particularly big meal.
It took everything for Hanzo not to cum in his pants, watching secretly from behind the doorway, as Cassidy groaned, shifting his gut foward so it jutted out just a little bit more.
“Urrf, oh man, feel like I’mma ‘bout to burst…” Cassidy whined, both hand on his stomach. “Fuck, I wish I had someone to rub my belly, it hurtss haah… so bad.”
Hanzo’s face flushed bright red as he made a small groan, he quickly ducked behind the door, hoping it would go unnoticed.
He was not so lucky.
“Who’s out there, ya better show yourself. I can’t really get up at the moment.”
Hanzo panicked, wondering if he should just run away. He decided that there was no way Cassidy could know about him being a perv, watching him while he bloated himself. So he took the coward's way out, quickly retreating to his room.
————-
The next time he found Cassidy with his big gut on display, was a few weeks later. He was not in the kitchen this time, but sat out in the open in the communal living room. Luckily most of the other Overwatch agents were out on a mission, so there was a small chance anyone would actually catch him.
He was laid back on the couch. Round belly still trapped behind clothing. It rested heavily on his thighs. Cassidy has his head tipped back, frantically chugging down pint after pint of heavy cream. His free hand ghosted his stomach, shaking it as he drank and filled his gut up with the fattening cream. He circled a finger around his deep belly button, his shirt tight enough to see the indentation, playing with it before pushing a finger deep inside. He groaned through a mouthful of cream, loving the internal pressure that resulted from it.
He drank another pint, letting out a long belch before going back to chugging. His jeans were already tight, but were growing even tighter on his expanding belly. His growing gut had now flopped over his belt buckle. The heavy cream causing his belly to become flabby and soft. With the belt buckle now obscured by his thickening lower belly paunch, it was near impossible to get it off.
Cassidy set down the cream, both hands hefting up his belly in an effort to reach the belt buckle. It was of no use, he let his belly flop back down, hearing the slosh and feeling how it jiggled as he did so.
Needing to get his belt off before he exploded he called out. “Hanzo get out here, you might be a ninja but ya definitely ain’t as slick as you thick you are.”
Hanzo came out of his hiding spot, where he was watching Cassidy’s belly expand.
“I need you’re help, I’ve gotten myself into a bit of a pickle.” Cassidy let out a weak laugh, which caused his belly to jiggle.
Hanzo was entranced by the movement. Forgetting what Cassidy asked him for a moment.
“Hanzo ya there? I didnt break ya, did I?”
This spurred Hanzo into motion who went to go stand in front of Cassidy.
“Would you be a dear and undo my belt buckle, I’m fit to burst and I can’t get it off” Cassidy at least had the sense to look a little ashamed.
Hanzo wordlessly knelt down in front of him. From this angle he could see Cassidy’s round ball belly, obviously filled up and heavy with liquid.
“Can you… uhhh…”
Hanzo was lost for words, not knowing how to ask Cassidy to hold his belly up so he could reach the belt buckle.
Cassidy seemed to understand and hefted up his gut so that Hanzo could reach. He was shocked by just how tight the belt was. Overcome with a desire to see him burst out of it, instead of unbuckling it, he pulled it up higher so that it was now squishing his lower belly, instead of being trapped underneath it.
Cassidy let out a pained moan “H-Hanzo whatcha doin’ there, it’s really tight.”
“You should be a good piggy and burst the belt off. Wouldn’t you like that? Knowing that you’ve grown your belly enough that it breaks your belt. You need a new one anyways, were you really planning on wearing this on a mission. Would you even have been able to concentrate, having your round gut be compressed by it, held back, unable to expand to its full girth?”
Cassidy was shocked by his rant, but extremely turned on by it.
“How am I supposed to burst it off, if I eat anymore my belly will explode before my belt does.” Cassidy whined.
Hanzo smirked, “You do know how butter is made, right?”
Cassidy looked confused for a second before he realized what Hanzo meant. He wanted to turn the heavy cream that sat heavily in his gut, into thick solid butter. To do so he would have to “churn” it, mixing it and sloshing it in his rotund gut.
Hanzo got to work, using both hands to knead his belly. He could feel the gurgles underneath his hands. He squished the side of the beer gut, causing it to jut out even more.
The more he kneaded the doughy fat, the less sloshing he heard, the cream slowly being turned into solid butter.
Cassidy groaned, feeling his stomach grow more and more solid with newly forming butter. It felt so good, in a weird way. The feeling of his belly, filled with liquid, slowly turn into something much thicker and dense, was completely new to him. Cassidy never wanted it to stop.
Hanzo kept pressed a palm into the swell of his stomach, it was met with resistance. It felt like he was sinking his hand into memory foam mattress.
Cassidy whined, “Urrrgghh…I feel like a beached whale…”
“You certainly look the part.”
Hanzo continued to knead his gut, it was still a little sloshy. Cassidy’s iconic BAMF belt buckle was currently holding back a huge mountain of lard, literally.
“Just a little bit more, you’re almost done.”
Cassidy, desperately wanting to pop his belt and let his gut fully expand, helped in Hanzo’s effort. With both of his hands he started squeezing the sides of his belly together, feeling how packed he was with butter. He felt like he was about to bust open, the belt had grown even tighter.
“If you leave forward a bit, the belt will probably come bursting off” Hanzo advised.
“I-I don’t know if I can move”
“Just try for me, here I’ll help you.”
Hanzo grabbed Cassidy’s shoulders as he shifted to sitting upright, instead of slouched bad against the couch.
“Oof… ahh.. haa”
Cassidy’s gut now sat heavily on his thick thighs, even held back by his belt and jeans. The belt caused a double belly to form, the top half of his gut hanging over it, obscuring his thick belt buckle.
“Try pushing out.”
Cassidy did as Hanzo said, using all his strength to push his gut out, he felt the belt buckle grow even tighter and heard a creaking noise. He kept going, belly expanding more as he pushed. The creaking grew louder before the belt snapped off, not able to take the immense pressure any longer. This was not the end as Cassidy’s jeans were still buttoned and constraining him. He sucked his gut in, as much as he could anyways, and quickly let it out. This sudden pressure was enough to cause the button to explode off, his flesh quickly pushing down the zipper. Flab spilled out , his jeans now framing his engorged gut.
He could feel his belly on his thighs, finally able to expand to its full size.
