Shinji Ikari began to urinate out of his tiny penis.

"Ahhh," sighed the fat blob boy as he emptied his bladder. He was sitting in his bariatric wheelchair at a table in the park, eating his way through some doughnuts.

hssssssssss

Shinji was pissing freely into his bariatric diaper. He was hugely fat, currently clocking in at 405 kilograms. He was also overwhelmingly gay, and his love of sodomy had rendered him incontinent in the control of his bowels. As such, the huge boy was currently swathed in a gigantic bariatric diaper, an enormous thing that he wore underneath his baby blue muumuu. Shinji was not urine-incontinent; he still largely had control of his bladder. But of course, wearing a diaper, and unable to get up from his wheelchair under his own power, had gotten him used to peeing whenever he liked.

hssssss

Shinji nibbled on a doughnut. He was taking a very large piss, probably because he'd drunk a lot of water before he'd left their apartment. Kaworu made sure to keep him hydrated, and did other things to tend to the health of his skin and the functioning of his innards. Additionally, Kaworu's Angel powers were actively at work on Shinji and keeping him from suffering most of the complications that would have normally come from his current level of obesity. Shinji didn't have diabetes, hypertension, gout, or most of the other obesity-related illnesses that normally plagued people who weighed almost 900 standard pounds. Kaworu kept it all away from him. Shinji would probably have been dead, or at least hospitalized, by this point, if not for Kaworu.

Hsssssss

Of course, even before he'd gotten to his current elephantine size, Shinji had gotten used to peeing as he sat. This is because he had an extremely small penis. It was barely seven centimeters when fully erect, actually somewhat less than seven centimeters. The former pilot of Unit-01 was incredibly undersized in his manhood, and he had been less than half his current size when the fat around his penis had made peeing standing up difficult. The blubber of his thighs, the swell of his fupa, the sag of his belly--it had all gotten to be too much around 200 kilograms or so, and Shinji had frequently dribbled as he'd stood in front of the toilet at that point. So, he'd taken to sitting down on the toilet to go pee. Sitting and peeing into a diaper was merely an easy additional step.

Kaworu walked up to Shinji as he sat at his table. "How is my precious boy doing?" he asked.

"Oh, mfm, I'm fine, Kaworu-san," said Shinji, scarfing down another doughnut. "I might be running out of doughnuts soon, though."

"I assumed you would, my pet," said Kaworu, "which is why I brought you these." He set a paper box down on the table and opened the lid.

Shinji's fat pig face rippled as he made an expression of delight. "Oooh, cupcakes!" he said with a joyful shout. Indeed, there were a dozen cupcakes in the box, yellow cake with chocolate icing. Shinji licked his lips and wiggled his plump fingers. Popping the last bite of the doughnut into his mouth, he reached for a cupcake as he chewed and swallowed.

Splrt!

"Mmf hmmf," he mumbled as he swallowed the bite. "A wet toot, Kaworu-san."

"I heard it, my precious boy," said Kaworu, walking around Shinji's vastness. He came to the back of the wheelchair where the big boy's ass spread wide. Shinji had an absolutely enormous bottom. Kaworu tenderly, possessively stroked Shinji's huge right buttock. "What a marvelous bottom you have, my pet."

"Num num," mumbled Shinji, mouth full of cupcake. He blushed as he chewed, icing smearing on his dimpled lips. "Well, Kaworu-san, I know you do like my ass a lot. You like how big it is."

"I do, Shinji-kun," said Kaworu. "I am so happy you have such a large bottom."

Shinji sighed lustfully. "I'm happy I'm exactly the kind of person you want, Kaworu-san."

Kaworu petted Shinji's head. Shinji whimpered. "You are indeed exactly what I like, my dear sweet boy." Kaworu stroked Shinji's huge left boy boob. He played with Shinji's nipple, visible through the fabric of the muumuu. Shinji moaned in pleasure, as he continued to eat.
