Shinji Ikari sat on the couch and pooped.
PLRRRBBBBBBTTT
"Mmm," he murmured, feeling his bowels empty out into his diaper. "Such a big load, Kaworu-san."
"A big boy makes a big mess, of course," said Kaworu Nagisa, sitting on the arm of the couch with a smile on his pale face. Shinji took up more than half the sofa on his own, so it was just easier for Kaworu to sit on the arms.
Kaworu tenderly poked his pale finger into the vast, mountainous slope of Shinji's belly. His finger sank into Shinji's gut all the way to the knuckle.
PLRR-BRRRTBBBBTTT!!
"Mooh, hoo hoo, Kaworu-san," said Shinji, body sloshing somewhat as he fidgeted, "your poke made me poop more!"
BLLRRRBBBBTTT
Shinji currently weighed 407 kilograms. An enormously fat load of teenage boy, he swelled across the sofa and onto the large ottoman Kaworu had placed in front of it to hold his belly. His gigantic gut was like a child's swimming pool, or a huge beanbag chair, an enormous swollen billow of flab. In the front, his belly button was very deep, not that Shinji could reach it these days anyway. Moving back from the belly, one encountered Shinji's flowing hips and vast thighs: the big boy was pretty bottom-heavy, despite the size of his gut. His thighs sagged over his calves, which were very fat and looked like large hams, while the calves themselves sagged over his chubby feet.
Atop the belly were Shinji's breasts. Big, fat boy boobs like sacks of lard sagged to either side of the belly's slope. Shinji had huge brown nipples that were currently stiff in the open air: he wasn't wearing anything but his huge bariatric diaper, into which he was currently emptying his dump.
Prlrlblllbbbtttt-PRT!
Hot, yellow-brown turds spewed out between Shinji's colossal butt cheeks. The former Eva pilot had an immense rear end, a massive seat that took up more than two of the sofa cushions all on its own. It also swelled behind him; Shinji actually sat somewhat forward on the sofa because the shelf of his ass jutted so far back. His shit pooled and puddled in his gigantic diaper. Today he was wearing a colored diaper as opposed to a printed one; he had plenty of each. Today's diaper was pink. Across the pink expanse of the seat there was currently a spreading brown stain, greasy and putrid, from the poop that was piling up within.
Kaworu tenderly stroked Shinji's upper arm. The fat boy had hugely fat arms, looking like hams like his calves did, that swelled into blobby forearms. His hands were fat, and his fingers were chubby, which made keeping a firm grip on things difficult sometimes, these days.
Shinji turned towards Kaworu. His fat face sloshed as he smiled. "I love you, Kaworu-san."
"Not as much as I love you, Shinji-kun."
"Ohhh," he moaned. His immense face flushed. Shinji had a soft forehead, and below his eyes, his cheeks bulged obscenely into enormous fat sags that made his face resemble some kind of farm animal's. His enormous, swollen cheeks oozed downward into very hoggish jowls that jiggled when he moved his head. Between and beneath the jowls was his triple chin: three huge, bulging chins, the third of which was so large it wattled and billowed like a goiter, or the dewlap of some cattle.
Even his nose looked fat these days. On either side of it, his blue eyes were beady, and had a look of animal greed and lust.
"You are the most special boy in the world, Shinji-kun," said Kaworu. He tenderly tickled the fold that separated Shinji's second chin from his third.
Shinji giggled, making his chins wobble. "Ohh, hohoho, Kaworu-san..." he smiled at him, causing his large dimples to deepen. "I wish we were having sex right now... I want you inside me."
PRRRBBLLLTTBBBB
"You must finish your dump first, my pet."
"Hehehe, that's fair," giggled Shinji impishly. "I have to make sure everything's out of my ass before you can be in it!" He tittered a laugh. His voice had become both deeper and shallower from all the fat around his throat. He also occasionally spoke in a somewhat stereotypically homosexual lisp, a trait that had developed the more he and Kaworu had lived in Northern California.
The door to the apartment opened. Ritsuko Akagi walked into the main living room, two huge bags in her hands. She wrinkled her nose. "Good God, Shinji-kun, your shit really does smell putrid. Aren't those diapers supposed to contain the smell?"
"Some do more than others, Doctor," said Kaworu.
"Besides, Doctor Akagi, you know me," said Shinji with a laugh. "Sometimes I just take such a massive poo poo... the smell simply can't be stopped!" He giggled at his own words.
"If you say so," said Ritsuko.
"Did you bring the treats, Doctor?" Kaworu asked.
"Oh, yeah, definitely," said Ritsuko. She walked in front of the blobby body of Shinji. She took a huge box from out of one of the huge bags, and popped the top off. "Four dozen cupcakes, as requested. Assorted variety." She licked her lips. "Wouldn't want our big boy to get bored with 48 of the same kind."
"Nom, num num," burbled Shinji, who started to drool.
grrbbgglll
His vast belly growled audibly. Ritsuko handed him the box, and Shinji set it on his belly. He immediately grabbed a cupcake, tore off the wrapper, and stuffed it in his mouth. His eyes rolled back into his head. "Oghm," he mumbled, icing already smeared around his lips, "thish ish sho good!"
In four bites, the cupcake was gone, and Shinji immediately began to eat another.
BLLRRRPPPBBBBBTTTTBBBB
The pink diaper bulged backwards visibly as yet more shit filled it.
Kaworu patted the vast diaper. "You're such an impressive defecator, Shinji-kun. It's truly admirable."
"Num num num," mumbled Shinji, sucking crumbs and icing off his fingers before reaching for another cupcake. His icing-smeared lips smiled. "Ohh, Kaworu-san, I love how much you love everything about me!"
"I do indeed, my precious pet. Every single aspect of your existence is beautiful, and worthy of being cherished."
PLLRRRBBBBTTTT
"Hahaha!" Shinji laughed, as beefy turds exited him. "I am a poop machine!" And he stuffed more cupcake into his mouth.
