"What?" Dave said "What did you do? I can't turn my head to see you.". Nate flipped open the laptop once more and spoke back. "I could lighten you up a bit... make you mobile again.". Dave heard Nate speaking in a high voice, much different than his normal voice. "How about pressing the revert button instead? I want to try some more stuff.". "Sure." Said Nate. With a quick press of the button, Dave's huge muscles began to lighten. It was like he was a baloon who had been untied. His 900 pound body dwindling, getting smaller and smaller. As he fell past 500, he was able to move his head... slightly. He looked over to see the 12 year old boy sitting in front of Nate's laptop. "Holy crap Nate! That thing can make you younger too?" Dave shouted as he sat up at 300 pounds. Nate looked back "Looks like it."
Dave was around 220 now, mobile, and shrinking back to 175. He sat down next to Nate and looked at the screen, showing a quickly depleting model of himself. Soon, it was back to his normal size, and so was he. Part two kicked in, and his soft 12 inch member became 11... 10, 9.. 8, 7, 6, 5 inches again. His huge balls shrank back to normal, and soon small sprigs of hair fuzzed out on his crotch and trailed up to his navel. He was back to normal. "Hey... can I try something else?" Dave said to the younger Nate. "Of course." Nate replied. Dave grabbed the laptop and began to adjust the nobs. "What are you doing now?" Nate said curiously. "You'll see." Dave said with a click.
Dave sat back again. Nate watched him intently. The transformation looked similar to his last. His muscles began to swell and bulge, growing and adding mass to him. His pecs swelled down and out, biceps swelled with power, his traps pointed. Shoulders bulked, and quads and calves huffed. Soon, he had gained an additional 30 pounds. The 200 pound Dave flexed and kissed his bicep as it grew... he continued to grow a further 50 pounds. He was a 250 pound bodybuilder. Nate was somewhat dissapointed. "That was a little less spectacular than the last change." He said, looking Dave over. Dave chuckled "Oh, I'm not done yet.". He motioned toward his 5 inch dick. "Take a look.". Nate did so, watching Dave's dick twitch... then shrink. 4 inches, 3 inches... 2 inches, 1 and it stopped. "I thought that it looked good on you before, so I decided to try it... just a bit smaller. Now, wait for this last part." Dave placed his hands on his abdomen, which Nate noticed was absent of defined abs.
His midsection suddenly swelled... looking like Dave had just drank and entire 2 Litre bottle of water, and it kept going. A small bulge became a medium one, and soon a crease seperated his gut from his groin... and it stopped. He stood, showing off the transformation. A body that any man would be jealous of... besides the decently large bulge of his midsection... and the 1 inch dick. "What do you think? Should we test it out?". Nate threw a pillow at him "Are you serious? I'm a kid now, you pervert!". Dave looked down "Oh yeah... I forgot.". Nate yawned, and Dave did too... looking at the clock they saw the time. 2 a.m... both of them were a little tired. Dave walked out of the room, shouted his new weight of 280 pounds and came back with a snug fitting shirt and a pair of jogging pants, which just fit him. Nate opened the program to revert them to normal, and as he clicked it, the program suffered an error. "Error in chnge.exe please restart". He yawned again... he could always change them back tomorrow.
------------------
Dave slept on the couch, snuggly and warm under a blanket. Hours passed, and he awoke, seeing the clock flashing 6:03 am. His stomach itched, and his chest felt tight... come to think of it, so did his legs and shoulders. He pulled off the blanket and walked to the bathroom.
Inside he became shockingly awar of his stomach, pushed far out from his body. It was pulling his shirt up! He noticed that his shoulders and biceps were pulled in far tighter by the shirt than just the night before... and his chest was much broader. His jogging pants looked painted on, and his stomach sagged over the band a bit. He pulled them down and saw that his 1 inch dick was almost a quarter inch now. He jumped on the scale, waiting for a number... 350... 355. He was growing! He shouted, and heard a clamour in Nate's room. Nate walked in, holding his boxers up in his childlike hands. He was smaller than last night, and a bit pudgier... he was getting younger, and was now 10 years old. "What's happening to us Nate!?" Dave shouted.
