Shinji Ikari was pooping away as Kaworu Nagisa pushed his wheelchair along.
brrbblll
PLLRRRBBBTTTTT
CHHHRGGBBTTT
"Ahhh," sighed Shinji contentedly as he emptied his bowels. "That sure does feel good."
Shinji was sitting in his huge bariatric wheelchair, resplendently fat and bloated. Shinji was a fat blob, incredibly obese: the other day he had weighed in at 404 kilograms. His wheelchair was like a couch, or a bed, and took up more than half the sidewalk as Kaworu rolled him along. It needed to be that big to support his incredible bulk. Kaworu had fattened him to an enormous size. His gigantic belly thrust in front of him, as big as a table, an ocean of lard. His plump breasts sat atop his gut, huge hooters, big boobs for the big boy. He had huge, wide hips, an enormous span of seat, and on either side of his jutting belly, his thighs were the size of tree trunks. Behind him, he had a huge ass, an enormous butt that was two full meters across.
BRRBBBBTTTT
Currently Shinji's big butt was emptying feces into his bariatric diaper. The huge boy wore a gigantic diaper, a vast size made for especially fat people. Kaworu custom-ordered Shinji's diapers and often got childish designs printed on them. Today's diaper had cartoon hearts with arrows stuck in them printed all over the vast swath of puffy whiteness. Over his diaper, Shinji wore women's clothing, as had become typical for him. He was draped in a dress the size of a large tent, a muumuu, this one a soft purple color with fancy flowers printed all over it. Around his bloated neck, he wore an enormous pearl necklace, and on his fat fingers he wore oversized rings: the ring on his left hand had an emerald on it, and the ring on his right hand had a sapphire on it. He was also wearing a large floppy sunhat; the sun was shining, and Kaworu had bought Shinji the women's hat to keep the sun off his sensitive skin. His huge fat face, with its sagging jowls and billowing triple chins, had makeup on it, blush and eye shadow and lipstick.
Overall Shinji resembled a huge fat woman, an enormous matronly lady of great obesity. It was only when you stared at him long enough that you realized something wasn't quite right about this first impression.
Pllrrbbttt
"Ah, what a nice poo poo," said Shinji, smiling smugly. "It always makes me feel so nice and clean when I take a big one like this."
He lounged comfortably. He always felt so nice and special when he was all dressed up and made up, when Kaworu took him out on the town. He nestled into the luxurious padding of his wheelchair, making it creak slightly from the movement of so much weight. His gut was supported by a large padded cushion, and there were cushions around his hips and thighs, as well. There was a cupholder on one arm of the wheelchair; currently it was holding a large butterscotch milkshake. Shinji hummed in pleasure and put the straw to his lips, taking a sip.
Brrbbllttt
Everything was perfect right now. He smirked at the feel of feces sitting around his buttocks and hips. He'd been incontinent for ages at this point, largely as a result of all the gay sex Kaworu had with him. He enjoyed the comfort and pleasure of his bowels emptying out. Of course, he enjoyed feeling full, as well, his engorged stomach stuffed to the brim with sweets and treats and tasty fast food. He actually enjoyed himself almost all the time, it was just a matter of the various different sensations the colossal obese boy felt throughout the day.
Kaworu was wheeling Shinji through the park. He paused under the shade of a tree. Then he lifted up the sheet-like hem of Shinji's huge muumuu.
"Oop! Feels a bit drafty, Kaworu-san," said Shinji, body jiggling as he fidgeted in place.
Kaworu gazed at the vast diaper of the giant fat boy. It was already stained brown, visibly so, and was bulging backwards. "Shinji-kun, this is... quite a large load."
"Oh, well, is that really so surprising?" Shinji waved his fat hand daintily. "I had a big breakfast this morning, even bigger than normal. And when I eat a lot, I poop a lot!" He laughed at his own words.
"It's just, I know you had wanted to see that movie..."
"Oh, yeah! Superman! I'm really looking forward to it, all the online reviews have made it sound great."
"My pet, I just want to be sure you'll be comfortably going to the theater with such a loaded diaper. The movie is more than two hours long. Will you be fine for that length of time with a messy diaper?"
"Oh, of course, Kaworu-san, that's no big deal." Shinji's hoggish face rippled as he smiled with his painted lips. "I haven't been bothered by a full diaper in years. It's actually pretty comfortable!"
"I just want you to be comfortable, my love. No matter what."
Shinji sighed with lust. His fat hand touched his flabby chest. "I love that you care so much about me, Kaworu-san..." He settled himself more comfortably in the wheelchair, causing it to creak again. "But I'm feeling just fine. Let's go see that movie."
Kaworu smiled. He leaned in, and kissed Shinji on the cheek. "Such a good boy."
Shinji giggled in pleasure. He sipped his milkshake again. And he leaned back casually in his diaper, filled with shit.
