Nate tried to move, grunting a bit, finally able to sit up, when he saw Dave across the room, stripping down. He exposed his taut muscles. God he was hot. "I guess you're giving it a shot now, huh?" Nate grunted as he steadied his fat body.
"I sure am." He grinned. He took two shots with the camera, front and back like it said, and loaded his model into the computer. He looked back at his massive boyfriend and grinned again. He knew what he wanted to change. He altered the model on a few dials, hunching over the screen so Nate couldn't see it. He thought another moment and picked the laptop up and took it into the bathroom, so Nate couldn't see at all. He set the timer down to 1 minute and clicked render...this was going to be an extreme change in that ammount of time.
Instantly, his cock twitched and began to grow. 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 inches. He was about to grab his huge dick but was cut off as part two kicked into high gear. His flat abs distended like someone was filling him like a waterballoon. His defined chest pumped up and smoothed. His slender waist swelled out in all directions, his tight ass plumped up and grew round. His thighs touched when no room was left for them to spread. His plumper fingers grabbed his new potbelly as his body swelled fatter and fatter.
Every trace of his athletic body was dissappearing under a substantial layer of fat. He grew and grew, his body taking on pound after pound. Soon, he stopped swelling. Now the last part took effect. His balls started to swell now, growing bigger and bigger in his sac, pulling it down as they got heavier. They grew and grew to the size of small grapefruits... they actually matched his enormous dick like this.
He looked over at the computer screen. It listed the change as complete. He grinned at the weight: 430... exactly half of Nates weight. He walked a step to the door, his body quaked all over... that was a little hot! He waddled to the door frame and barely squeezed himself through, in fact, his hips got stuck for a few moments. The floor creaked below him while he walked into the living room where Nate lay.
"Hey big boy" he said, jokingly. Nate looked over at him and his eyes widened. "What did you do to yourself? You're huge! All over!"
Dave rubbed his potbelly. "Yeah, I figured we've been lean guys for a long time... and it's hot and all to be in shape with you... but I figured it'd be hot to be fat boys together. As for the dick and balls... well, I thought my big man would be hungry for some meat and gravy. Had to have enough to feed you."
Nate felt his miniature dick getting hard again. The thought of being so big and out of shape with his now half as big and out of shape boyfriend was turning him on. "Well, it's gonna take a lot to fill my belly... get that thing ready for service, huh?" Dave obliged gladly, stroking his huge meat and gut. The 15 inch member started to stiffen, growing quickly, hardening until it stood 22 inches. He waddled over and helped Nate to lay on his stomach, then presented the hard dick to him. Nate smiled and opened wide.

15 minutes later, Nate was contented at the feeling of a full stomach. Dave sighed happily at the feeling of empty balls. Nate looked him over. "I can't believe it. You can make obesity hot." Dave laughed and said "I could say the same about you."
Nate rubbed his enormous gut and said "you know....
