A wife concerned her husband isn't eating enough feeds him the entire planet.
He's been working so hard he even skipped a lunch the last Friday at work-- he must be starving all the time, oh, what will she do? She worries her thick, 220lbs man is going to keep eating less and less...he only put on 5 pounds last week! She decides that desperate times call for very desperate measures.
She straps him to his desk chair and starts feeding him massive orders from every local restaurant, fast food place, even ordering bags of chips and other meals from supermarket take-aways, from how desperate she was!
As he ate, his desk and all his work got knocked over by his swelling, gurgling, hungry, glutton of a belly that beckoned for more while he tried (and failed) to complain about the table breaking due to all the food being shoved down his mouth.
He couldn't deny he loved it when his wife fed him and rubbed his belly, especially to a degree where he went beyond full, but she didn't understand why she was going so far this time around!...Well, somehow, he got so full, so stuffed, that his belly did a full circle (pun intended) and sounded like it was starving again!
Hearing this, the detemined wife was resolute in feeding him anything at hand, even things that shouldn't be edible were beginning to be sucked down by his voracious maw that would stop at nothing to satisfy both his and his wife's urges. He had long since broken out of the chair, with his massive fattened up booty, legs that outsized the thickest tree trunks, and even blobby arms, but he didn't try to move or waddle out of the way, instead he only allowed the feeding to be easier, using hoses or whatever means necessary to make him bigger.
Making sure he had a drinking source, she got a hose directly connected to a river to give him a plentiful source of water... though soon enough, the river and the ocean it ultimately ran towards were running out, as he was drinking everything, eating everything, to the point where the barren planet itself would become just a crunchy meal for this galactic glutton.
His wife, still stubborn as ever, assumed that he still had room for dessert, and once he opened his mouth to sound out a large burp that wobbled and rumbled his enormously fat body around its cosmic surroundings, he had the Moon for a lovely dessert, that'd bwomph him up several more sizes, his belly dominating his figure, followed by impressively, outrageously blubbery, round, perky moobs, and an ass that'd make a fertility goddess blush.
"I hope I fed you enough honey..." She laid down on his cheek rolls and planted kisses all over him, her love for him being as big as he now was. <3
