Late Night Stuffing
#2 of Jolo & Jack
Jolo pushed at his brother's hips and tried to roll the rat over. He gritted his teeth and shoved, his paw sinking into the soft flesh of Jack's side. By the time he got his little brother on his side, the big rat had to catch his breath. Petting over the rolling curves of his brother's rump, it didn't take long for Jolo to regain focus, taking his stiff cock in one paw and leaning in to guide himself between his little brother's ass cheeks, so plump and warm. He entered his brother and held himself inside, his big rat dick giving a happy nod inside the tubby rodent.
"You're so fat," Jolo whispered and started fucking his little brother. Jack kept sleeping. It was a school night, and they had to get up in less than four hours, but Jolo had to cum in his boyfriend one more time before he could sleep again.
He knew he would be nudging Jack awake soon enough, the young rat full of sperm and soon to be filled up with more food. Jolo wondered what he would feed his brother in the morning. His cock if he had time.
Jolo giggled a little and fucked. His little brother jiggled in response and Jolo ran a paw over and around Jack's round belly. It stretched out in front of the rat a good foot or so before curving downward toward the bed where it rested like a heavy plushy.
And like a plushy, Jack often cuddled with it as he slept. It wasn't so easy for him to know what to do with his arms anymore. They were fatter now too, and Jolo found it so cute the way the pudge would bunch up against Jack's chins.
"Such a fatty," Jolo squeaked and sped up a little, careful not to wake Jack while he raped him. "Gonna make you fatter little brother."
Holding his brother against him and crushing his strong hips into the cushion of Jack's wide rump, Jolo decided he would heat up a couple cheese danishes while Jack got dressed. He would put the first in his mouth as soon as Jack slung his backpack over his shoulder, and he would give him the second as they walked to school. The little chunker should be wiping his muzzle clean by the time they got through the front doors.
He kept Jack full all the time. He hoped he could make Jack's belly show out the bottom of the boy's shirt by the time he sat down in his first class. He would take whatever's left of the milk they had in the fridge with them and tell Jack he had to finish it before they got to school. If he brought it along, Jack would have no choice. He wouldn't dare waste it and he would be too embarrassed to be seen drinking out of a milk carton by anyone at school.
Jolo felt at his little brother's plump breasts and shivered. The kids in Jack's grade were making fun of him for those. God, he had made his brother so fat; he had tits!
Jolo plunged his dick in deep. He held it there and trembled slightly each time he plunged into Jack's butt. He was going to cum.
Jack's classmates were poking at his big round gut and calling him Fatty Ratty. He was just a scrawny little rodent in their old school, but now he was known as a fat kid. Students chuckled at him as they cracked jokes in the hall. He was a sweating, heaving joke in gym class.
"Gonna make you fatter," Jolo panted, squeezing his brother's sleeping form and doing his best to hold off. But then he saw the image of a much fatter future Jack waddling with him to school. They wouldn't be able to walk together if Jack kept growing. They'd have to get a ride, not even in a bus, but probably in their mom's SUV so Jack could get in and out through the sliding door. Their family would have to alter things at home so the youngest and fattest son could get around. And if Jack kept growing, the portly rat wouldn't be able to get around at all...
Jolo held his cumming cock deep inside of his brother. He felt faint and pleasantly sleepy as he shivered in orgasm, filling his little brother up while the fat boy snoozed. He was such a lazy kid now. Jolo smiled and petted Jack's side again, keeping his cock buried in the young rat's tailhole as globs of rat sperm pulsed into the boy's overweight body.
Mixed up between the sensible moments of afterglow and the senseless ones before sleep, Jolo asked himself if he was really going to make his brother as fat as he had fantasized. He didn't think he wanted to; that would cause so much disruption in their lives. It would change everything and make it all very serious, and it wasn't really something they would ever be able to come back from.
But at the same time, Jack was getting really fat. He had only been fattened up by his big brother for about eight months, and he had gone from a gangly underweight squeaker to a bouncing obese porker. He obeyed his big brother and ate what he was given, and Jolo had secretly pushed him to eat more and more once he saw a visible reward in the young rat's body.
He had noticed how the added weight had gotten in Jack's way, but he just loved seeing his little brother grow soft and round. He wanted to make that belly so enormous it took over everything the rat tried to do.
Jolo breathed out, trying not to get worked up again so that he could get a few hours of sleep, but laying next to his fat little brother didn't make resting easy. He turned partway on his side so he could look over Jack's sleeping body and jerk lazily at his own dick. Would he really be able to stop fattening his brother up? He really didn't know. He would keep it up for now. Maybe taper it off after the holidays.
The big rat beat his shaft in his paw rapidly and groaned. All that holiday stuffing was going to wreck Jack's body beyond repair. Jolo edged up against his brother's body again and slipped himself back in. This little fatso was going to be an immobile blimp.
