Shinji Ikari took a soft, wet shit into his diaper.

Sppllrrrrbbbblllll

"Oop," said the fat boy, big chins wattling. "Poo poo!"

They were relaxing in one of the local parks, near a large garden full of abstract sculpture. Kaworu had taken Shinji to a Chinese restaurant for lunch, and, of course, Shinji had made an absolute pig of himself. He'd eaten more than 20 entrees and multiple orders of both fried rice and lo mein noodles. They were going to get dessert later, of course, but Shinji had requested that they go to a park so he could digest a bit. The huge boy had found he enjoyed to sit in nature while food sat in his stomach. So they were here, in the shade of course: it was a mild, faintly warm day, but Shinji was so fat that even in this weather, he'd sweat if he sat in the sun for long.

He currently weighed 405 kilograms. He was an enormous, porcine boy, a large, fat blob that billowed in all directions. His huge ass swelled behind him and stretched across about two meters, an extremely wide and potent seat. His vast hips bulged against the sides of his bariatric wheelchair; it was probably time for Kaworu to get a larger wheelchair to accommodate his fat pet's growth. In the front, his immense belly sat before him on the cushioned pad of the wheelchair, almost as large as the rest of his body put together. He had a hugely big gut, bigger than most tables, and with so much interior space that a full-grown adult could have sat comfortably inside it. Atop his belly, his large boobs sagged to either side of the slope like deflated beach balls. The fabric on the muumuu he was wearing today was a bit thin, so you could see his big, soft nipples. His huge arms were loaded with lard, so big around that he couldn't fully rest them at his sides.

pllrrbbbblll

"Hmm," hummed Shinji mildly as he took his soft, wet poop. He often defecated not long after eating; the entrance of a new meal into his system would push the remnants of the old one out. Beneath his muumuu, he wore a huge bariatric diaper. They were so big that Kaworu had to custom-order them these days, and there was the option of different colors or colorful prints. Today, Shinji was wearing a diaper that had cute cartoon teddy bears on it. The vast diaper could have served as a robe for a smaller person, but every bit of the disposable material was needed to cover Shinji's immense backside.

Splllrrbbbtttttt

"Ahh," he sighed contentedly as more and more poop came out. It was all semi-liquid, too, a goopy slurry of waxy yellow-brown. These were his favorite types of shit. The big, thick logs that sometimes came out of him were occasionally somewhat erotic, given that the sensation of pooping them out was not dissimilar to Kaworu's cock going up his anus. But they could also be somewhat uncomfortable, with the way they would tax his sphincter and rectum. So, mostly, Shinji preferred a nice, non-solid shit. The emptying-out always felt pleasant, and there was no strain placed on his butthole. Shinji didn't like strain. As you might imagine, to be this fat, he'd become rather lazy and slothful, so anything that took too much effort was something he wasn't fond of.

Kaworu, standing beside him, reached out, and placed his own slender hand atop Shinji's chubby one. Shinji looked up at his caretaker and lover. Kaworu smiled gently down at him, red eyes glinting. "Ah, Shinji-kun," he said gently, "you make the cutest expressions when you defecate."

Shinji blushed, a pink flush coming to his fat face. His large, hoggish jowls and big, buttery chins tinged with pink. "W-Well, Kaworu-san," he said, "it does always feel good to let it out." He shifted a bit, causing the wheelchair to creak from the movement of all his bulk. "I always feel so good after a nice shit."

Pllrrbbbbttttt

"Ahh," he sighed again. He licked his lips, and wiggled his fat fingers. "I am, ah, probably going to be ready for dessert when this poo poo is done."

"What would you like, Shinji-kun? Around here, as you know, there is the ice cream parlor, the doughnut shop, the bakery, and the chocolate shop."

"Oooh," he cooed, blue eyes sparkling as he considered his options. He licked his lips again, and rubbed the crest of his sloping belly. "Oh, hoo hoo, ice cream would be good... oh, but so would doughnuts... oh, but so would cakes and pies!" His beady eyes gleamed with a haze of greed. "Oh, I wish I could eat them all... I wish I could eat everything in every store!" grrmbl, growled his belly, as his appetite was really worked up.

"Well, Shinji-kun, perhaps I should decide for you?"

"Oh, yes, sure, Kaworu-san!" said Shinji, smiling, fat cheeks dimpling as he made his happy expression. "You're always right and you always make the best decisions. I'll let you decide for me."

Kaworu smiled, pleased at the level of control that Shinji always surrendered to him. "I think, my pet, that we should go to the doughnut shop first. We have not had doughnuts in a while."

Pllrrbbbtttt

"That's true!" said Shinji, nodding as his anus deposited more feces into his diaper. "It's been, like, two weeks since we went to the doughnut shop. It would be nice to go there again."

"And then, my pet, if you are still hungry after doughnuts, we can go to the ice cream parlor for a change of pace."

"Oh, good! That sounds like a great plan." Shinji again licked his lips and wiggled his fingers. "Ooooh, I'm gonna eat two dozen... no, three dozen doughnuts!"

"Or four dozen, Shinji-kun."

"Or four..." said the fat boy lustfully, his eyes gleaming with an overwhelming desire to eat.

"Let me know when you are done pooping, Shinji-kun, and we shall go."

Spplrrbbbtttt

"I think I'm finishing up, Kaworu-san," said Shinji, shifting back in his seat. The immense amount of poop in his diaper squished against the back of the wheelchair. It smeared against his cellulite-covered buttocks, and stained the back of the diaper a putrid brown. "I think it shouldn't be too much longer before this load is done. Any minute now!" He giggled in delight, thinking of the desserts to come.
