Shinji Ikari's enormous diaper was extremely full of poop.

"Oh, I love fried chicken," said Shinji, taking a crispy chicken tender in his chubby fingers. He dipped it in the container of honey mustard, brought it to his mouth, and took a bite. His big, fat chins rippled as he chewed, along with his billowing jowls. Grease and oil and sauce oozed down the droopings of his plump face. He ate the chicken tender completely. Then he reached for another one, and this one was dunked in barbecue sauce before he brought it to his lips. He chewed. He swallowed. "You know, Kaworu-san, buuurp, fried chicken is just a particular itch. When you really want it, nothing else will do."

"That seems sensible to me, Shinji-kun," said Kaworu, sitting across the table from him at the fried chicken restaurant. It was a beautiful spring day: the sky was blue, the sun was shining, there wasn't a cloud in the sky. So they were eating outside.

"Num num," mumbled Shinji, eating yet more chicken. The huge fat boy was eating enough food for at least half a dozen normal people, but of course Shinji had eaten himself out of normal portions ages ago. An infinity of chicken strips were laid out on platters at the table, along with seasoned french fries, mashed potatoes with gravy, cole slaw, biscuits, and a few chicken sandwiches here and there. Shinji had long ago decided he preferred strips and tenders to fried chicken on the bone. Bones just got in the way, and the former pilot of Unit-01 didn't like anything getting in the way of him stuffing his face.

pprrbbbbbtttt

Grease dribbled down Shinji's chins as he chuckled at the sound from his ass crack. "Hmm hmm, not quite done pooping yet, I guess." He could feel the working of his vast guts as greasy, goopy feces puttered into his bariatric diaper.

"Your ability to generate feces is truly impressive, Shinji-kun. I actually think you should be proud of it," Kaworu said.

"Hoo hoo, I guess," said Shinji. He chuckled. "I'm a super pooper!" He shifted his bulk a bit in his bariatric wheelchair, and he could feel the weight of his shit sagging down behind him into the wheelchair's huge, cushioned seat. He could feel the soft, mushy squish of it against his gigantic buttocks, each pale, cellulite-dimpled cheek cushioned by the soft mass of his waste.

The smell of it gave him a wide berth. The gargantuan fat boy had caused the outdoor seating area at the chicken restaurant to be almost entirely abandoned. Something stank, and nobody wanted to sit in the midst of the smell. Nobody knew what it was, of course. Few could have dreamed that the obese boy in the dress, already an absurd sight, was also packing a diaper full of turds under the billowing swaths of his muumuu.

Shinji guzzled down some french fries. He had long since ceased to care about his poop-stink. In fact, he'd grown somewhat perversely proud of his ability to generate it, to poop so freely and sit comfortably in it for so long. It made him feel decadent and pampered, and very special, because he could do something almost nobody else would be permitted to do. It was one of the signs of how treasured and cherished he was by Kaworu. Kaworu's care of him meant that the normal rules for things didn't apply to him. It made him feel smug.

Taking big bites of mashed potatoes, Shinji smiled at Kaworu. "It's so nice to have these big new diapers, Kaworu-san. Ever since I grew past 400 kilograms I've needed this bigger size. There just wasn't room in the old size for me and my poop."

"You must be kept comfortable, Shinji-kun, as you grow and grow."

Shinji gave his enormous ass a shift to the left, deliberately smearing his left butt cheek dirtier with the goopy turds. He grinned. "I feel so special... all the time now, I feel so special. And it wouldn't have happened without you, Kaworu-san." He sniffed, and smelled the shit in the air around him. His dump was really starting to stink now. Grease and drool oozed down his chins and jowls as he smiled, feeling very satisfied. "The more I eat, the more I poop... and I know you want me to keep eating more, and more, and more. And I want to keep eating more, too. I'm so hungry all the time these days." His fat hand reached out and patted his enormous belly. "What goes in must come out, you know. BUUUAARRRPP!!" he belched loudly after finishing his sentence.

"You are the most beautiful boy in the world, Shinji-kun. I love you so much."

Shinji blushed, and smiled gently. "I'm so glad for the life you've given me, Kaworu-san."

He reached for another chicken strip. The poop shifted in his diaper as he moved.
