Shinji Ikari's enormous folds of back fat oozed and sagged.

Prrrrrttttt

"Mmm," he mumbled, shifting where he sat on the couch. It was an enormous couch, but Shinji's gigantic ass took up multiple cushions on it.

He was sitting in the living room of the apartment he and Kaworu shared. Kaworu was sitting next to him, and they were watching a movie. Actually, they were watching gay pornography. Kaworu had gotten Shinji interested in porn and erotica as he had taken him under his wing and begun to mold him into more of a homosexual. These days Shinji loved consuming porn, especially gay porn. Even now, the TV screen was filled with sodomy.

"Oh, this orgy is so sexy," cooed Shinji, licking his lips. The big, fat boy was mostly naked, wearing only his enormous bariatric diaper. With no clothes on Shinji's true enormity was on display. The huge boy currently weighed in at 404 kilograms, a spreading vastness of blubber that oozed behind him, in front of him, and to either side. There was a large ottoman that Kaworu had placed in front of the sofa to act as a cushion for Shinji's huge belly; without it, the massive gut would have sagged down to the ground. His vast hips swelled bulbously to either side, oozing in slopes down to puddles of flab on the sofa cushions. His huge butt took up more than two sofa cushions, and it jutted backwards in a shelf that was so sizeable it actually pushed Shinji forward on the cushions.

FFRRRRTTTTT!!!

"Ungh," he gurgled, his fat face sloshing as he worked his mouth. His voluminous chins sagged down his front, while his pie-like jowls flopped over his neckline. "Oh, Kaworu-san, I'm really feeling that Italian food from lunch right now."

BRRRAPPP!!!!

Kaworu tenderly put a hand on Shinji's mammoth gut. "It's all right, my pet. You know you are free to fart in my presence."

"I just... don't want to interrupt the porno," said Shinji. He settled his plump hands on his vast midsection. "I'm trying to watch, but I'm just... my guts..."

Prrrbbbttttttt

"I'm sure you will be defecating soon, my precious boy," said Kaworu, stroking Shinji's belly again.

"I hope so," said Shinji, somewhat petulantly. "I could absolutely use a nice poo poo. It would feel so good."

Kaworu looked over at Shinji. His fat face was twisting and sloshing. He really was bothered by the troubles in his guts. The big boy wasn't always bothered by what he ate, but sometimes it caused him trouble, especially when he ate particularly large amounts of cheese.

Kaworu moved his hand up a bit on Shinji's belly. "Let me see if I can ease your digestive issues, Shinji-kun." Kaworu pressed his hand more deeply into the belly, his fingers sinking into creamy, fluffy flab. Suddenly, bright orange hexagons began to flare in the air around Kaworu's hand. They spread over the expanse of Shinji's gut.

Frrrrrttttt-Splrt!

"Uh!" grunted Shinji. "Ohhh, that feels better..."

PLLLRRRRRBBBBTTTTTTTT

"Ohhh, yeah, that's so nice..." Shinji said, sighing in pleasure as his bowels absolutely unloaded. An absolute mudslide of poop blew out of his anus, a chunky flow of waxy yellow-brown turds.

PLLRRBBBTTTTT

"Ahhhhh," sighed Shinji in relief as he kept pooping.

PLRRRBBTTTTT

Flow after flow of hot, soft feces came out into his diaper, quickly building up a large mound of waste inside the vast enclosure. Kaworu glanced over to the side. He could see the huge diaper being stained brown by the entrance of his fat pet's waste.

PPLLLRRRBBBBBTTTT! PLRT!

"Uhhh, that's it, I think," grunted Shinji as he felt his bowels die down. He was sitting in what must have been five pounds of shit. "That feels so much better." He smiled at his boyfriend. "Thanks, Kaworu-san."

"Don't think anything of it, my pet," said Kaworu. "Now, let us resume watching."

Shinji looked back to the screen. "Ohh, that guy has such a big dick," he mumbled. He licked his lips. "I wish I could suck it..." Deep within his shit-filled diaper, his tiny penis was fully erect.
