Kaworu guided Shinji into the bedroom. Shinji waddled in, his stubby, undersized penis already hard beneath his hundreds of kilos of fat.

"I can tell you're excited, Shinji-kun," said Kaworu gently, whispering in his ear.

Shinji's huge fat face was flushed and red. "Ohhh, Kaworu-san," he moaned, huffing and puffing, his enormous body rolling and rippling as Kaworu steered him towards the bed. He was so excited. "We... we haven't made love in a few weeks. I'm just so..."

"Shh," said Kaworu. They stopped before the bed. Kaworu kissed Shinji on the cheek. "I am going to fill you full of love, Shinji-kun."

"Ohh," moaned Shinji.

Kaworu had continued to fatten him. Shinji was now 270 kilograms, very close to a whopping 600 pounds in the standard system. He was bigger around than he was tall. Much bigger. An absolute blob. His face was huge and piggish, blubbery cheeks giving him permanent dimples as they sagged into hefty jowls and a buttery double chin. Shinji smiled, revealing the ghost of a third chin.

He was naked, putting his flab on full display. His arms were bigger around than most men's waists, covered in fat, especially up top. His huge boy breasts were jutting in front of him and sagging down his belly; Shinji had an impressive pair of tits, with big, soft nipples. His belly sagged to his knees, even slightly past them, and swelled in front of him, a big, sloping ocean of blubber, covered in stretch marks. He had a vast belly indeed, and it wrapped around to become huge, thick rolls of back fat, hefty love handles that contributed to Shinji's circumference.

"Such a good, fat boy," said Kaworu, walking around him. Shinji's bottom was more than five feet wide and jutted behind him, forming a womanly shelf ass made of two gigantic buttocks. They sagged down onto his thighs, which were wider than the waists of some lesser fat people; these touched to the knee and gave him his hefty waddle.

Kaworu walked up behind Shinji and sank into him from behind. He reached his arms around Shinji's enormous body and hefted his huge boobs. Kaworu played with Shinji's nipples, causing them to stiffen.

"Ohhh," moaned Shinji. He was already dripping precum, leaking out from the depths of his fupa, itself buried deep beneath his gut. Kaworu was pressed against him, and Shinji could feel the other boy's own penis, so big and stiff. Kaworu was very big indeed, and Shinji loved it. "Kaworu-san..."

"Come, my pet," said Kaworu, guiding Shinji forward. Shinji was gently lowered onto the bed, where he shifted forward on all fours. His huge belly sagged all the way down onto the mattress, pooling around him. Kaworu took a moment to admire Shinji's ass. He stroked two fingers down the right buttock. Shinji whimpered. "By the way, Shinji-kun, I ordered pizza about five minutes ago."

"Mrmr, pizza?" mumbled Shinji, suddenly very interested in something other than sex.

"Mm-hmm. Six large pizzas, with breadsticks."

"Oh, ohh," Shinji moaned, the thought of food making him even more aroused.

"They'll be here in thirty minutes," and Kaworu unbuckled his belt as he said this. He dropped his pants and boxers to the floor and kicked them aside. Shinji shivered as he felt the cold air on his inner ass crack, as Kaworu parted his huge butt cheeks. "So, Shinji-kun... let's help you work up an appetite."

Kaworu guided his penis to Shinji's anus. Then he put himself inside, and thrust.

"Ohhhh," moaned Shinji, as Kaworu pushed in, pulled back, pushed in again. Shinji was panting, huffing and puffing, moaning and groaning as Kaworu fucked him like a stuck pig. "Uh! Uh! Ohh, ohhh, Kawo... Kawo... Kawo..."

Kaworu thrust even deeper in, burying himself up to the balls in Shinji's anus.

"OHHHHH," moaned Shinji in utter delight as he was filled to the limit. He was beginning to sweat from the strain, his unfit body and lack of stamina taking their toll. A bit of drool began to slop out of his open mouth.

Thrusting deeper and harder, Kaworu wasn't even breaking a sweat. He heard Shinji moan again and smile. "Oh, Shinji-kun, you truly do love this, don't you?"

"Uh, uh, ohh, Kawo... Ka..." He was panting hard, unable to get words out between heavy puffs of breath. He was also overcome with erotic bliss. Kaworu was right. He truly did love being fucked. He loved it! And Kaworu thrust more and more, more and more, heavier, harder, Shinji couldn't think straight, he was panting and drooling and he threw his head back-- "UHHHHNNNNNNN".

"Ah, that did it, didn't it?" said Kaworu with a smile, stopping his thrusting. And it had. Shinji had orgasmed, his undersized penis erupting with an explosion of semen.

"Uhhhhnnn," Shinji groaned, his exhausted arms and legs giving way. He oozed forward onto the bed, belly propping him up off the mattress some. "Ohhh," he moaned again as Kaworu pulled out of him, one final spasm of ejaculation coming from Shinji's penis as he did. Shinji was breathing hard and covered in sweat. He stank a little, from the buildup of sweat in his fat folds. Kaworu reflected that he'd need a bath soon. Or ideally a shower, where Kaworu could scrub him thoroughly.

"Such a good boy," said Kaworu, gently stroking Shinji's head of dark hair. "You lie here and rest a bit. I'll go get cleaned up."

Shinji was still swimming in the haze of the afterglow. He couldn't think for a brief while.

But then, after a while... he smelled it.

Grease. Cheese. Sauce. Meat.

And he knew he needed it.

"Mmmm," he hummed. The bed creaked loudly as he hauled his huge body over, massive fat body leaving quite an indention in the mattress. "Rngh," he grunted as he hauled himself to a sitting position, huffing and puffing as he did.

"Shh," said Kaworu. With that surprising strength of his, he helped Shinji maneuver backwards. A pile of pillows had been made at the back of the bed, and Kaworu propped Shinji up against it.

There was a gurrgle as Shinji's belly awoke. He smacked his lips. "Mmm, mmm, hmm, Kaworu-san, is, ah, is the pizza here?"

"It sure is, Shinji-kun," said Kaworu. He set one of the big pizza boxes down on top of Shinji's belly. "Now, dig in. We can't have you going hungry."

Shinji felt his penis stiffen a bit even now, and he felt incredible desire. He loved food even more than sex, these days. So he popped the top off the pizza box, picked up a slice, and began to stuff his face.
