Naruto was about to scoff at the other ninja who had condensed themselves into this stagnant place to just continually have sex and jack off and grow completely beyond them when Kiba clapped him on the shoulder. Naruto turned around and was met with Kiba's grinning face.

"I know what you're thinking Naruto. But let's just stay here for awhile. I mean, it's not like we can't just keep growing later. Why not relax for awhile."

Naruto frowned at Kiba's nonchalant attitude and was about to shrug Kiba's hand off his shoulder and leave him behind when Kiba suddenly moved forward, reached around, and grabbed Naruto's dick with his other hand. Naruto gasped and his body tensed. He hadn't been expecting this. Kiba continued to grin as he slowly moved his hand back and forth. Naruto grit his teeth as he felt his cock stiffen, blood rushing into the shaft. Naruto had a rather large cock and as he grew harder and harder Kiba was able to grab the shaft with both hands, his own dick hardening and pressing against Naruto's back. Naruto started thrusting his hips into Kiba's hands as pre-cum started oozing out of his slit, running down the shaft onto Kiba's hands. Kiba used the natural lubricant to make jacking Naruto off all the easier. Naruto's cheeks flushed as he felt himself getting closer and closer to climax. With a few shuddering jerks Naruto's cock spasmed and blew forth a torrent of white gold. Naruto screamed in ecstasy the normal feeling of orgasm increased dozens of times over thanks to his new size. In this moment Naruto's mind briefly blanked and he suddenly shot up a few feet. Kiba found himself flipping over Naruto's shoulder and landing on his back on top of Naruto's dick. It was wide enough that he could lay easily on it without fear of falling off. He grinned up at Naruto who was giggling at Kiba's predicament. Naruto focused his mind and shrank himself back down to "normal" size. Kiba put his hands on Naruto's shoulders and said, "Time to return the favor."

Naruto lowered himself to his knees and found himself face to crotch with Kiba's thick cock. It swelled in front of his eyes, longer and thicker as Kiba made it and it alone enlarge. Naruto eagerly opened his mouth wide and took Kiba's monster dick in, his big mouth filled completely with Kiba's meat. Saliva pooled around the organ mixing with the pre-cum as Naruto slurped, his tongue darting in and out of Kiba's piss slit. Kiba moaned in pleasure and slowly rubbed his shaft, his hands running over the veins that were bulging out. Naruto managed to pull the cock out with a loud "pop" just as it erupted in a stream of cum. The cum flew forward and suddenly disappeared into nothingness. Kiba, panting from the release, barely heard Naruto say, "Hey, why did his cum disappear like that?"

The ninja that had first talked to Kiba smiled and said, "It disappears because it's leaving the Realm of Eternal Growth and filtering down into other universes."

"Universes?" Kiba panted out. "There's more than one?"

"Of course! There are hundreds of different universes out there. You just can't see them from here. Our cum disappears down into those universes and sometimes lands on planets. If it lands on worlds that have humans on it the cum turns into that green dust that you two must have found and waits until it can infect someone. When it does, that person begins to grow and, depending on the will of the infected, will keep growing until he gets up to us! See, the cum only works on human males because our cum comes from human males."

"So you guys aren't all from the same universe are you?" Naruto asked, pointing at the various other males there.

"Oh we mostly came from the same universe, the same universe that you two come from. It's like the cum traveled back down our growth paths until it landed back on our planet. The biggest differences among us is that we come from different villages and different time periods. But none of that matters anymore. I mean, what's the point of being loyal to a village that is microscopic in a microscopic universe?"

Naruto and Kiba nodded, agreeing. Naruto glanced down at his toe and wondered if the village was still on it somewhere, lost among the folds of his flesh. Heck,if it was still there it would have fallen into one of his pores by now and entered his body. Naruto pushed the thought from his mind. There was nothing he could do about it anymore anyway. Instead he turned to Kiba and said, "So what do you want to do now?"
