Nate and Dave walked back out to the laptop and sat on the couch, staring at the now mystical object. Nate attempted to lean in and change his model back, but his now big gut was in the way. Dave chuckled "What do you want to change?"
Nate looked himself over... "I don't know yet. But I'd like to go back to normal for a while." Dave nodded and made some modifications. Pressing render, Nate's big belly and swollen muscles shrank back to normal, and his tiny prick grew back to it's 9 inch erect state. "Wow... that was weird." Nate said as his body toned back up from the deflation. Dave was still clicking away at the computer. Nate tried to see over his shoulder, but dave wouldn't let him.
"What are you doing?" Nate asked. Dave just chuckled a little "You'll see." He clicked the mouse and closed the laptop. Nate looked at him curiously... then his body began to tingle. Another change? He looked his body over, but saw nothing different. He had no clue that his 29 year old body was now 28, and rapidly getting younger. The years were melting away, and Nate began to feel more energized. His pudgy stomach faded away. "I don't know what you did, Dave... but I feel pretty horny... I haven't felt an erection this strong in a couple of years at least." He looked at Dave, who grinned. "Wait a second... you made me younger so I'd be hornier?" Nate asked. Dave shrugged "Not exactly."
Nates muscles began to shrink as he entered his teens again. His height began to drop rapidly as his years fell away. "What the hell?!" Nate shouted as he dipped to 16 years old. His dick shrank a little, and the hair around it thinned. His muscles undeveloped, and his height dropped."Stop it dave!" He shouted as his voice uncracked. He grabbed at his dick, trying to maintain it's length, but it dwindled down to 3 inches, the hair faded away, his muscles became un-noticible, and his light facial hair totally dissappeared. He continued to shrink, his years were dropping off until he was only 8 years old, looking up at dave.
"Why did you do this?!" He wailed. "Just for fun..." dave replied.
Nate began to shrink again, more years dropping off. He was 7, then 6, then 5. He was so small, looking up at Dave. He felt like he was still getting younger... but it had stopped.
