Shinji Ikari felt poop come out of him as he stuffed his face with cake.

Plllrrrrttttt

Prrrdddd

Brrbbblll

"Oghm," he mumbled, mouth full of cake and icing. His fat body took in a lot of food throughout the day. And he was so gay, so homosexual, that he'd long since destroyed any control he had over his bowels, sphincter, and anus. So, whenever his large intestine had a sufficient load of waste, it simply emptied, and the big, fat former Eva pilot would poop himself, heavy flows of feces exiting him entirely out of his control.

But Shinji didn't mind. He was currently sitting naked on the couch, wearing only his gigantic bariatric diaper. He continued to eat the enormous chocolate ice cream cake sitting on a stand in front of him, his blubbery jowls and bulging chins rippling as he chewed. Far behind his fat face, his enormous bottom continued to make greasy, gurgling noises as turds flowed out of it into his diaper.

Prrrrbbbblll

Kaworu stroked his huge belly. "What a marvelous specimen you are, Shinji-kun."

"Ohhh, Kaworu-san," moaned Shinji, icing smeared on his fat cheeks, "ohhh, I'm pooping." He smiled childishly as he said it. He giggled, and took another bite of cake.

"I can hear it, and smell it, Shinji-kun," said Kaworu. He stroked the massive swell of Shinji's gut. The huge fat boy had a belly so big Kaworu could have sat comfortably inside it. It was pale and hairless, and riddled with stretch marks. "This beautiful belly of yours... it makes a lot of waste. Fortunately, so much more of your food is converted into beautiful fat."

"Uhhhnnn," rumbled Shinji, his flabby throat, hidden by his sagging chins, making a soft wattling noise. He took several more bites of cake. He was almost halfway done with it, and he wasn't even close to full. And this was after an enormous lunch of Chinese food and pizza. He was so incredibly fat, and gluttony was what had gotten him there. Kaworu had transformed him into an enormous eater.

Brrrrbbbbbbllll

PLLRRRRRRRRTTTT

And an enormous pooper.

Shinji's fat face contorted comically. A huge log, a big, thick turd, was oozing out of him. His poop usually wasn't solid; his diet full of sugar, starch, fat, carbs, and processed foods ensured that most of the time he took very goopy, semisolid shits. But every now and then his bowels would send him a big python of poop to deal with. It was actually raising his heart rate to shit it out. The couch creaked as Shinji fidgeted in place, over 350 kilograms of enormous teenage boy sloshing and jiggling where he sat.

"Everything all right, my pet?" asked Kaworu.

"Ohh, mm, Kaworu-san... it's a big one," said Shinji, smiling with chocolate-stained teeth. The turd was squirting out of him, slowly but surely. He was incontinent but never constipated.

Kaworu smiled serenely. He came and sat beside Shinji on the couch. He leaned into him. He began to pet Shinji, to stroke the top of his head. Shinji let out a shuddering breath. He put down his fork.

"Such a big, beautiful boy..." whispered Kaworu into his ear, as he petted Shinji like a dog. Shinji whimpered in his throat. He continued to shit out the enormous log. Kaworu leaned in, and Shinji opened his mouth eagerly to accept the kiss.

PLLRRRRTTTTTTTT

The huge log of poop finally exited Shinji, and it was followed by a big flow of nearly liquid feces. Shinji moaned in delight as he was kissed as he shat. Kaworu stroked his belly with one hand while his other hand caressed Shinji's cheek. "K-Kaworu-san..." he whispered, leaning in for another kiss. "I love you."

"I know you do, Shinji-kun. My perfect fat pet."

"Touch me, touch me," he moaned, and Kaworu did, his long and gentle fingers running all over Shinji's obese form. He caressed his sagging chins. He fondled his floppy boy boobs. He stroked his flabby upper arms. Shinji cooed and whimpered in erotic bliss. He loved it when Kaworu would touch him. Now Kaworu stroked down his back, hands fondling the flabby slabs of back fat that piled atop Shinji's gigantic shelf ass.

PPPPBBBRRRRRrrrbbbbbb

Goopy poop came out of him. "Ohh, Kaworu-saaaan, let's have seeeexxxx," moaned Shinji. "All this pooping... it makes me want you to fill me up."

Kaworu stroked Shinji's cheek. "No wonder you are so incontinent, Shinji-kun."

"Ohhh, yes," moaned Shinji, shifting in his seat, his huge fat legs jiggling as he wobbled where he sat. The huge fat boy was wallowing in his poop, consciously smushing himself against the gigantic load of feces in his diaper. "Ohh, yes, yes, yes, Kaworu-san, I love it when you make love to me... I can't control my bowels... and it's totally worth it... to have sex with you..."

Kaworu kissed him again. Shinji whimpered. "Very good, Shinji-kun," said Kaworu. "We will make love soon enough. But first, finish your cake."
