Ritsuko sank into Shinji's enormous body as she kissed him.

"Mmm, mmm, hhmm," murmured NERV's former chief scientist as she Frenched the former pilot of Unit-01. Her long, shapely body was stretched across the enormous bulk of Shinji's fat form. Her long, toned legs splayed across his huge belly, sinking into his meters upon meters of blubber. She draped across Shinji's plush form like he was an enormous stuffed animal. She continued to stick her tongue down his throat.

Shinji's eyes rolled back into his head amidst his fat face. He was in absolute bliss. His porcine head was covered in red kiss marks, from his porky cheeks to his billowing jowls to his sagging chins, all three of them. The big, fat boy sat there and was worshiped. He could barely think he was so aroused.

"Ah!"," cooed Ritsuko, pulling up for air. A trail of saliva connected Shinji's mouth to hers. She watched it dangle, glinting, for a moment, then smacked her lips to break it. She smiled down at the vast teenage boy. "So fun... did Misato ever kiss you like that, Shinji-kun?"

"N-No... hff... no, Dr. Ak-kagi, she... whew... didn't..." Shinji twittered, his plump hand going to his fat chest with its ripe boobs. He pawed a bit at his flabby chest area; his heart was beating like a drum, and there was a sheen of perspiration on his pale, gelatinous body. He was so incredibly unfit and out of shape that even an extended makeout session counted as a workout for him. He breathed hard now that his mouth was free.

Ritsuko smirked to see it. "Somebody is out of shape," she cooed, playfully tugging at Shinji's second chin, hanging like a planetary ring between the bottom of his jaw and the beefy start of his third chin. She shifted off the bed and grabbed a large cup with the Wendy's logo on it. "Here... some Coke. Just what the fat boy needs." She held the straw up to his mouth, and Shinji greedily guzzled up the soda. He sipped and sipped and sipped.

She pulled the straw away. "Buuurrrp," he belched softly.

"And then... some cream," said Ritsuko, leaning into his huge body again. She had a container of whipped cream, and she maneuvered the nozzle to Shinji's mouth. Smacking his plump lips, Shinji opened his mouth, and Ritsuko squirted a mountain of whipped cream onto his eager tongue. Shinji mumbled with a fatty sound in his throat as he swallowed it all, leaving smears of creamy white around his mouth.

Ffrrrtttt

Ritsuko smiled. "Always so gassy. You'd repulse most women, you know that, Shinji-kun?" She sniffed, and grimaced. "And they always stink! You really are a toxic waste dump in your guts, aren't you, big boy?"

"Ohh..." moaned Shinji, a flush coming to his fat face. He got aroused when Ritsuko degraded him. He loved being told how fat and smelly and inadequate he was.

Ritsuko smirked down at him with a bit of a wicked look. "Lucky for you, Shinji, fat and smelly and stinky is just my type. And young, too. God, you really are perfect. What luck, that Nagisa and I have the same tastes. I could have fattened you up, but nothing like the job he's done. Perks of being an Angel, I suppose. You can bend and break some rules of human physiology."

Frrrttttt--splrt!

"Muhhhnmm," mumbled Shinji. "Oooh, Dr. Akagi... that one was wet."

"I heard it." She grinned. "God, sometimes I admit, I have fantasies of you pooping all over me. It's so hot to watch Nagisa change your diaper. What a shit machine you are. And of course he's fucked you so much you're totally incontinent. Fat and digusting and useless..." she bit her lip, "it's so sexy." She leaned in.

"Mmfm," mumbled Shinji as she kissed him again. It was another one of those times when Shinji couldn't believe what a wondeful life he led. This was beyond anything he could ever have imagined. He was Kaworu-san's special boy, totally loved, and on top of that he got doted on by Dr. Akagi now, too. It was like a dream. Sometimes when he laid in bed, his CPAP machine on his plump face, falling asleep, he wondered if the dream of his life was something he'd eventually wake up from. That he'd go to sleep, and wake up back in Misato-san's apartment in Tokyo-3, with Angels and Evas and NERV and his father all crashing back into his reality.

Then he'd wake up for real, and he'd be gloriously fat once more, and his paradise life of eating and shitting and sodomy would resume. And he'd almost be ready to cry tears of joy at how happy he was.

"Oooh," said Ritsuko, pulling away from him again, "you want me to stick a dildo up your ass? Since your shart's got you all lubed up. Let's get one of Nagisa's big ones."

"Ohh, yes, yes," moaned Shinji, wiggling his fat fingers. "Oh, stick something in me, Dr. Akagi!"

"First, let's undo this diaper of yours," Ritsuko moved around to the huge vastness of Shinji's ass. His enormous butt was more than two meters wide and jutted behind him in a bulbous shelf, upon which rested his layers of back fat. Lately Kaworu had started to buy Shinji bariatric diapers in single colors, in addition to the childish prints on some of his other diapers. Shinji's single-color diapers were always infantile colors: butter yellow, baby blue, baby pink. Today he was wearing a lavender diaper, and now Ritsuko undid the tape at his enormous waist and pulled the diaper down in the back, exposing the huge butt cheeks, pale and pockmarked with cellulite, the size of beanbag chairs. "Now..." she put a hand to her chin, "the most efficient way is simply to roll you onto your side so I have straight access to your anus. Here we go..." she began to tip Shinji over onto his side.

"Oooh, oof, c-careful, Dr. Akagi," said Shinji, flailing helplessly as his gigantic bulk was gradually settled over onto his right side on the bed. He couldn't move himself at all any more, and was useless in the face of someone more nimble and strong manipulating his vast form. Now he was laying sideways on the bed, his blanket-sized diaper open and spreading off to the side at an angle. His belly and ass were like mountains oozing and sloping down onto the comforter.

"Now... which one..." Ritsuko was looking over the row of dildos that Kaworu kept on a shelf near the bed. "Oooh," she grinned, "this one. It's so thick!" She came around and was holding a safety-cone-orange dildo with the diameter of a soda can. It was about half a meter long. "Your huge stretched asshole can definitely fit this, Shinji-kun."

"O-Oh!" Shinji blushed. The dildo was also studded. "Oh, Dr. Akagi, I'll definitely try to fit it." He smiled, looking like a pig in a wig. "My anus is nice and stretched, thanks to Kaworu-san!"

"I know," said Ritsuko with a lascivious grin. She walked around to the heaving mound of Shinji's huge bottom. She guided the dildo in between the heavy, ponderous ass cheeks. She found the loose, sloppy, sopping anus, around the butt cheeks covered in wet shart. "Shinji-kun, let's fill you up!" And she shoved the dildo into the anus.

"Ohhhhh," groaned Shinji as the massive dildo was shoved into him, more and more, deeper and deeper, hard and thick and studded, he blushed and moaned and his fat nipples got stiff. He was so full now, his rectum stretching wide as the big butt plug was shoved further and further into him. He was intensely aroused. He would have been intensely aroused if Kaworu-san had been doing this, but somehow Dr. Akagi being the one made it even more erotic. Further and further, deeper and deeper, the enormous dildo went further in, further in....

"All in!" said Ritsuko with a smirk. "My God, Shinji-kun, you really are as loose as a cheap whore back here. You swallowed this thing up! I honestly think there's room to spare. Nagisa must be feeding you some really big dicks."

"Ohhhh...." moaned Shinji, a fatty moan of absolute arousal. His piggish face was flushed red.

Ritsuko saw his face. She saw his look. She saw him tugging at his fat nipples. "You're ready to pop... I might as well pop you." She reached down into the folds and billows of blubber around Shinji's pelvic area. She dug and dug, deeper and deeper, through the fat of his underbelly, through the flab of his fupa... "There," she said, taking hold of the sticky, stubby penis. It was less than seven centimeters long. "What a small dick. I'm always amazed by it. You're lucky you're mostly a fag, Shinji, there's no way you'd ever please a woman with this thing, even before you chubbed up."

"Ohh... Doctor... D-Doctor Akagi..." burbled Shinji.

"Yes, yes. To business," said Ritsuko, and she began to tug and stroke. She used her long fingernails; she had noticed that Shinji was especially aroused when she'd claw at his dick and balls with her fingernails. He seemed to get off on the rough treatment. It made her grin and blush. A huge, fat blob of a boy, helplessly shitting himself all day long, addicted to rough treatment and heavy anal sex... what an absolute mess Shinji Ikari was.

And she loved it. She blushed, and tugged, and tugged...

"Ohhhh yeahhhhhhh," moaned Shinji as he ejaculated, his popgun penis blasting away with a load of sticky spunk into Ritsuko's waiting hand.

PLRT!

At that moment Shinji's anus gave a huge belch and shat the dildo out, covered in oozing shit. It bounced onto the comforter, staining it horribly. A terrible stench of turds was in the air.

But Ritsuko was loving it. "Man," she said with a grin, "you guys must replace the comforter in here a lot, with how much you must stain it from fucking and shitting." She licked Shinji's semen off her fingers. "So sweet! Your spunk is always sugary, Shinji-kun. Must be all the desserts you eat." She watched Shinji on the bed, huge body rippling as he heaved breaths like a beached whale. "I wonder... could I give him a blowjob? The logistics of it are... daunting."
