"What else can that book of yours do, Ric?" Alex asked, motioning tp his now 13 year-old father. "I mean... this is pretty amazing on it's own... but the things it could do!" Ric smiled and nodded, he turned to the fridge and began chanting another, inaudible spell that he had memorized. Ric pulled back and said "You should see what we'd be capable of. Ric looked at Sean as he reached for a box of cookies in the cupboard, watching the 13 year-old shrink once again. What little muscle definition he had smoothed out, and a bit of baby fat appeared on his stomach. Any hair, besides that on his head, faded away. He got shorter, going from 5'4" to 4'10. Alex looked at his dad, knowing he had to be 8 or 9 years old now, and seeing that he couldn't reach the cookies. He walked over and lifted his Dad high enough to reach them.
"Ric, he's getting too young now. How can we stop it?" Alex asked. "We can't. As long as we let it run it's course, the spell will fix him in the end. Anyway... haven't you noticed anything different?" Alex looked around, and focused on Ric. He looked taller... and more defined. So did Josh! "What does an accelerated 15 minute puberty sound like to you?" Ric asked. "You mean... we're growing up?" Alex said, noticing a deeper voice. "Yeah. You and me are 14 now.. Josh is 13." With that, another growth spurt hit. "Sorry. We're 15. Josh is 14.". Alex looked over his body, it wasn't as clearly defined as Ric or Josh's... come to think of it, the men on his mother's side of the family were somewhat chunky.
Ric slapped at his now 6 inch flaccid dick, and he grew again. His cock swelled to 7 inches, and he was only 16! Alex grew as well, and noticed he was just an inch under Ric. Josh was the same length as well. Another round of growing hit. Josh was as tall as Ric now, probably around 5'9". Alex was 5'11". He noticed his pudge was increasing as well... he was probably 180 pounds. The last growth hit Ric, increasing his height to 5'10". He was a lean, muscular 170 pound 18 year old with a 9 inch cock... Alex was a soft, round 195 who stood 6 foot 2, with a 7 inch dick. Josh grew one more time to 6 feet, 185 pounds of muscle, with an 8 inch dick... The three new 18 year olds laughed at their new bodies. "Hey Josh, I bet me and you are more hung than Mr. Mendes!" Ric said. Josh laughed in agreement.
Sean walked over to his gargantuan son. "Wow... you sure don't get that from MY side of the family." He said, prodding Alex's gut... Then, the prodding stopped. Alex looked down to see his father dwindle a few more years back to around 5. "What ever, little Man." Alex said as he picked up his dad. "Now, we have important grown up things to do, so you're going to go take a nap.". Sean yawned, ignoring his son, who was now 13 years older than him, and his patronizing tone. He plodded up the stairs, realizing he was quite tired, and went to bed.
"What should we do with our new bodies?" Alex asked. Ric replied "I think it's obvious. Let's have an erection contest.". Alex looked at him "Oh, you mean... who's the biggest?" Ric nodded. Josh began, he concentrated, and his 8 inch dick began to harden... 9... 10... 11... 12... 13 inches! "Looks like I'm a grower, boys.". Ric went next.. 10... 11... 12 inches. Not too shabby. Alex went last... 7... 8... 8 1/2 inches. "Ha ha!" Ric mocked. "You sure got the short end of this deal.". "It would look bigger if I weren't all flabby like this! I know it." Alex replied.
Ric had been fighting it all day, but the sight of his own new body and huge dick was just too much! He reached down and began to stroke it... Pressure began to build in his groin... his balls pumped as he moved his hand like a piston. Precum dribbles out of the tip of the long shaft, and in only a few moment he cums. Ric's balls tighten, his dick pulses out of his hand, and the sticky white goo drips to the floor. He pulls out the tissues and wipes himself off... taking note that there's less to wipe. His dick looks smaller... Ric shrugs it off as he cleans up. "I've got a great idea. Let's take these new bodies for a skinny dip!" Alex says, rubbing his small stomach. "Sounds like an idea to me." Says Ric "But first, I've got to use the bathroom."
Ric walks down to the bathroom and positions the bulky, flaccid member. He isn't used to being so high up from the toilet, but he gives it a shot. Ric lets out a stream, not noticing his balls pulling closer to his body, his dick shrinking, and the hair retracting on his groin. It diminishes to 7 inches... maybe 16 years old. Ric notices that he feels really aroused again, but shrugs it off as a change in hormones. He walks back into the kitchen to see Alex and Josh talking about the book. Josh looks at his brother and notices another change. "Hey.. did you do another spell, Ric. So Alex wouldn't feel lonely having the smallest dick?". "What are you talking about?" Ric asks, looking down. He gasps, noticing that he's lost 2 inches in length. The realization causes his dick to perk up again, swelling to only 9 inches. He can't help himself, his hands fall to his dick and start pumping once again. In a few moments, he comes once again. Alex points as Rics balls shrink again and his erection dwindles another 2 inches. His 7 inch hard-on begins to fade into a 5 inch flaccid dick... it looks like it did when he first went to 14 years old.
Ric can no longer help himself, he begins to beat his 7 inch erection, cumming time after time. 6 inches... 5 inches... it grows younger and younger, passing by 12 years as it shrinks to 4 inches. His pubic hair dissappears, his balls pull almost into his body.. He's now masturbating with only one hand. 3 inches.. 2! He's using 2 fingers and a thumb to whack. He orgasms once more, but nothing comes out. 1 inch... 1 thumb and finger stroking his infantile cock... a quarter inch.... gone!
The three young men look about in disbelief.
