Kaworu wheeled Shinji into the bedroom. Shinji sighed in the pleasant coolness of the apartment. He waved a plump hand in front of his fat face. "Such a hot day today, Kaworu-san!"

"It was only mild, Shinji-kun," said Kaworu, pushing the bariatric wheelchair closer to the double-king-sized bed. "Though, of course, for a boy as big as you, even a mild day must feel a bit warm."

"That's true, I guess," said Shinji, puffing out a breath. "I always heard years ago... that fat people get hot easily." He stroked the billowing swell of his enormous belly. "I guess now that I'm fat myself... that's me, too."

Indeed, Shinji was very fat. He clocked in at 407 kilograms, just barely under 900 standard pounds. He was wider than he was tall, a massive dollop of fat that expanded out in all directions. His vast belly was as big as a children's swimming pool, an ocean of blubber in one long, swelling slope. His hips were wide and swollen, with vast pouches of fat that trailed down to his gigantic thighs. Behind him, his huge butt oozed out and back in two mammoth cheeks, naturally parting slightly to give him a cavernous ass crack. His meaty slabs of back fat rested on this shelf ass, and they led up to his lardy arms, as big around as the legs of some lesser fat men. Sloping down his belly were his huge boy boobs, like deflated beach balls, giving him immense cleavage in the green muumuu he was wearing. It all led up to his fat face, with his beefy triple chins and its sagging, pouchlike jowls and cheeks. The former Evangelion pilot weighed more than eight times his old self. The old, thin Shinji could have sat inside the new, fat Shinji's belly.

Pprrrt, came the flatulence from Shinji's rear end.

"I must say, my pet, I'm rather surprised," said Kaworu, red eyes gazing serenely down at his toy. "We were out for four hours and you did not have a bowel movement once."

"Oh I know, Kaworu-san," said Shinji, somewhat proudly putting his fat hands on his fat hips. "I can't explain it! I almost always go poo-poo at least once when we're going around town."

"Perhaps because you defecated in your sleep particularly impressively last night," said Kaworu, stroking his pale chin. "That, combined with your bowel movement at breakfast, may have emptied you out in ways somewhat uncharacteristic for your usual routine."

"Maybe," said Shinji, putting a chubby finger to his plump lips.

Kaworu put a hand on Shinji's shoulder. Shinji felt thrilled at the touch: his tiny penis stiffened, and the nipples of his moobs grew hard. Kaworu leaned in, and said gently into Shinji's ear: "So, since your bottom area is, for a change, free of mess... shall we have sex?"

"Oh, yes, yes, yes!" said Shinji with a cheer. His third chin, so huge and thick, wattled back and forth as he enthusiastically shouted. "Yes, Kaworu-san, mmm, hoo hoo, some nice sex would be perfect! I want you inside me!"

"Up we go," said Kaworu, putting his thin, pale arms under Shinji's goopy, flabby armpits. With the Herculean strength he possessed as an Angel, Kaworu was easily able to lift Shinji out of the wheelchair and several feet off the ground. Shinji's belly plopped onto the carpeted floor of the bedroom, and dragged across the carpet as Kaworu moved him onto the bed. With some slightly cumbersome maneuvering, Kaworu had Shinji on all fours on the massive bed. It creaked under his weight.

Kaworu threw back the skirt of Shinji's tent-sized dress, exposing the vastness of his back fat and his waistline. His pale skin was folded and pockmarked with cellulite, especially on his thighs. It also exposed his bariatric diaper, a massive thing covering his massive backside. Kaworu often ordered Shinji's custom-made diapers with childish prints. This one had hearts and rainbows printed across its large, crinkled surface. Normally at this time of the day Shinji's diaper would have a putrid yellow-brown stain in the back, the calling card of his defecation. But today, it was clean. So Kaworu went to the taped straps and pried them off, and pulled the diaper down. Shinji's massive, cellulite-covered butt cheeks were visible for the world to see. His ass was two meters wide. Shinji moaned and cooed at the cool air on his buttocks.

"Kaworu-san..." he breathed, sounding huffy, sounding aroused. "Kaworu-san... bigger, bigger, as big as you can."

"Of course, my pet," said Kaworu, unbuckling his belt. He unbuttoned his shirt, pulled it off, and pulled down his pants and briefs. Completely naked, Kaworu's lithe, thin body was an absurd contrast to the mammoth plop of fat flesh waiting for him on the bed. Kaworu's penis was much larger than Shinji's even at normal size. But suddenly orange hexagons flared to life around it. Orange light gleamed around his crotch as Kaworu used his AT Field to increase the size of his dick. It got longer and thicker. Longer and thicker. Longer and thicker it kept growing, well past normal human sizes, a penis that almost looked like an elephant's trunk.

Finally, Kaworu had a comically large phallus. It was a meter long and bigger around than a soda can. Guiding the super-penis carefully, Kaworu walked up to Shinji on the bed. Shinji moaned like a cow as he felt the stiff penis brush against his left buttock. Like he was opening a set of double doors, Kaworu parted the butt cheeks, their weight and gravity causing them to slump and ooze over the tops of Shinji's thighs as they sagged to either side. Shinji's butthole was loose and sloppy, and it was even leaking a bit of brown goop. Kaworu guided the mega-penis towards the anus, aiming the tip straight for the sloppy opening. Then, he slid the tip inside, and pushed.

"Ohhhhhhh," moaned Shinji as Kaworu entered him. Further and further, bigger and bigger, deeper and deeper, Kaworu drove his penis into Shinji's rectum. Finally he hit the very back of the rectum and even penetrated slightly into Shinji's colon. Of course Shinji's prostate was stimulated heavily. Then Kaworu pulled back out slightly, and thrust back in with all his might.

In, and out. In, and out. In, and out.

"Ohhh yeahhhhhh," groaned Shinji in rapturous pleasure as he was sodomized. Kaworu fucked him like a stuck pig. The big, fat, gay boy was being absolutely stuffed with cock, his bloated, overloaded rectum and colon so stretched and loose that taking such a massive penis was easy doings at this point. Shinji Ikari could probably have had sex with a horse and he would have lived to tell the tale. He was so gay, so queer, such a faggot, that he'd grown able to take massive dicks up his ass, and he actively craved the biggest cocks he could find. Indeed, the average man would probably have disappointed Shinji at this point. The average human male's penis was simply too small to satisfy Shinji. Fortunately, Kaworu's Angel powers ensured this was never a problem.

Thrusting and thrusting, Kaworu brought Shinji closer and closer to climax. He gripped Shinji's hefty flabs of back fat for support as he plowed in and out of the mammoth fat boy. Drool was oozing down Shinji's chins. Shinji's fat body sloshed and jostled from the motion of the sex. His big third chin jiggled back and forth like the dewlap of a cow. His fat breasts sloshed and plopped against each other, their nipples hard as a rock. The upper reaches of his belly bounced and jiggled and jostled, while the lower vastness of the belly sagged onto the bed. Shinji was almost ready to cum. Closer... closer... closer...

Kaworu thrust in as deep as he could, and slapped Shinji's right ass cheek to make it jiggle.

"UHHhhhnnffffgggg" groaned Shinji, sounding like a cow.

Splrt

Splrt

SPLRT

Shinji's tiny penis erupted with semen. Buried deep in his folds and slabs of fat, Shinji's cock was only about six and a half centimeters when fully erect. He truly had a micro-dick, and most of his semenal emissions remained trapped in his sticky, sweaty fat folds.

SCHLRBT!

An explosion of goopy brown slop blasted out around Kaworu's dick, coating the innards of Shinj's ass crack.

"Ohh," moaned Shinji as Kaworu pulled out of him. "That felt so good..."

Kaworu gazed down at his stupidly-large penis. It was covered in runny feces. "Ah," said Kaworu, "it seems you had to do a slight bowel movement after all, my pet."
