He wasted no time as he dug his hands into the cake and began rapidly shoving pieces into his fat face. Each bite caused his to grow more and more, his body blowing up as well.
Tasting all of this, he didn’t need to die to know where he was, he was already in heaven, having the best food, the best friends and the best parents a kid like him could ever ask for.
He kept tearing through the cake, each bite having a drastic effect on his body, growing bigger and fatter as he stuffed himself with the calorie and fattening-laden cake.
His body kept expanding as more and more calories were forced into it. His belly soon hit the floor in front of Gohan, which for him was a huge milestone, and he continued to grow in height as well, the weight and adipose all pushing his chubby head up. And since he wouldn’t be able to reach the top of the cake, he had been all the while using telekinesis to break pieces of it and send it to his mouth, and Goku and Chi-Chi helped him out a bit with the feeding as well.
Within a few minutes, half the top of the cake and most of the two bottom layers had been devoured by the Saiyan fatty, his clothes managing to stick on for this long being an impressive feat.
Since more people were getting fat, there were making large pieces of clothing, as well as normal sized clothing was being made of a material that could expand to many sizes, but some had their limit and they were being worked on to remove the limits.
Gohan’s giant body however, was a different case, he was practically nine feet tall, his body was three to four feet wide at every corner, his belly, sides and back fat being involved. His arms were much thicker, to the point where there were now thick arm rolls. His clothing was almost struggling to hold his body in.
He would soon get to the point where he would become an immobile and ginormous mountain of lard.
The cake itself had lots of ice cream and lard in it, which only fueled Gohan’s desire to eat every last bit, not wanting to let the prize his parents got for him to go to waste.
He even watched his expanding ball of flesh block out the bottom of his vision almost entirely, he would need to rely on his parents to feed him soon.
His giant belly rumbled, as Goku helped him rub it to rid of the discomfort, since the child’s body was almost completely consumed by his own lard. His mass had always been visibly expanding around him, quickly swelling with fat as thousands of calories filled him out every second.
The cake was halfway finished and it felt like they’ve been here forever, but they didn’t mind. Gohan was happy either way. By now, he was an enormous blob that could just barely feed themselves with his hands. His neck was halfway about to vanished into his bulk, leaving him as a face and arms on a giant mass of fat.
Did this bother him? Absolutely not.
