Marco's 9 inch member swayed as he entered the bathroom. With a pleasant "whoosh" he began to empty his bladder of it's contents. He hadn't been in the room when Francisco had stated the new spell, and was unaware of what was happening. The stream splashed into the bowl, and with every drop that dibbled out, Marco's cock got younger. The 9 inches slowly retracted down to 8 and a half... then 8 1/4th. Luckily, he didn't need to go that bad. Without a thought, he shook the last few drops free and dried his member off. For some reason, every time he touched felt amazing. After a few tentative pokes, it stood rock hard out in front of him, pushing 12 inches. He had already peed it down to when he was 20... he was in for a surprise.
Marco stroked his still huge dick and walked back into the living room, where Francisco sat, prodding his small half-inch erection. "I feel AMAZING!" He shouted to Francisco. "I don't know what the side effects of getting young like that are, but I'm so horny! I can't keep myself from whacking!" He plunked down on the couch, pumping his 11 3/4ths of an inch dick right in front of Francisco. Instantly, he came. White splatters shot from the tip, many of them leaking down Marco's fist. Each stream that came out caused it's own little change. His dick lost a little size, going to 10.. 9 inches. His nutsack pulled tight on his balls, and the thick mat of hair on the base of his dick lightened a bit. He had lost a further 3 years. Francisco was at a loss for words! Had he said the spell out loud? He quickly rifled through the book, trying to find a way to stop what he had done to Marco. Page after page flew by, and Marco continued to moan and stroke his junk into nothingness.
It was no use! All he could find were similar shrink spells, growth spells, and none of them were permanent! Even if it was 12 inches long, a baby dick was still a baby dick, with all it's limitations. Francisco jolted at the sound of Marco's next moan. He had cum again. 9... 8... 7 inches now. His ballsack pulled higher, the hair began to turn a new, lighter color, and was covering far less area. 4 years this time. Marco's once impressive 12 inch erection had been reduced by a little over half his age, and more than 2/3rds of it's length. Marco took note that he was now stroking with his one hand. He saw his 13 year old manhood and moaned once more, he wanted to stop, but he couldn't! Another spurt of cum shot from his shorter shaft... but only once. He watched as it shrank once more 6... 5 inches... he wasn't cumming! Francisco knew that he had beat himself to pre-puberty. Finally, he was able to pull his hand away from his now 4 inch flaccid dick. "What the hell!?" He said, as he was overcome by an urge to use the bathroom. Marco jumped from the couch.
"Wait Marco, if you use the bathroom, your dick might dissappear like mine!" He shouted "You need to give me time to fix this.". Marco turned, trying to hold it in. "It's going to come either way Francisco. Either on your nice floor, or in the toilet!" Marco ran into the bathroom and sat on the toilet, making sure that he was incapable of spraying the floor with his mini-meat. His now 11 year old dick sprayed with all it's might, dropping year after year from it's shaft. 3 inches... 2.... It was the size of a 5 year-olds dick. All the hair had faded away, and his shrunken balls moved right up to his body. It immediately became hard once more, shooting to 2 1/2 inches. He couldn't resist himself... stroke after stroke, blank orgasm after blank. His dick got younger and younger it's last time. 2 inches... 1 inch... a quarter... nothingness. Marco rubbed his now smooth groin as he walked in a daze into the living room. "It's gone." He said.
Francisco was way ahead of him. He chanted the growth spell once more, and on Marco's groin began the new dick of his life. A half-inch nub that stuck out over pea sized balls... It erected to a full-inch. "This is just not good enough Francisco." He said, poking the tiny rod. "How did this happen?". Francisco rubbed his chin "Uh... it must be the effect of coming into contact with my shrinking dick." He said, not wanting to let on. "But cheer up. We'll be old men one day, who won't worry a bit about impotence. Now let's test these out."
Francisco loomed over Marco and began to stroke his new cock. It perked up as he rolled the head in his hand. Slowly but surely, the same old feeling came back, and in a moment Marco came. Nothing came out of him, but he managed to orgasm. Marco had to admit, it was a great feeling. He leaned over and did the same to Francisco's 1 1/4 inches. He was overcome, and eventually did the same, liquidless orgasm.

Ric, Alex, and Josh had stopped standing in awe of Ric's dissappearing cock. They put on a few pairs of Sean' Jeans and began running to Francisco's. Alex had wrapped a cloth around 3 year-old Sean, and was getting worried about his father's age.
