Trevor was disgusted. Kyle the caveman absolutely reeked, like an entire football team's worth of BO. And he was hairy too! His pubic bush was absolutely huge, wiry, and matted together. Trevor's loincloth body was shoved up against the smelly sweaty bush and Kyle's long, thick caveman cock. Kyle was hard and he was tenting Trevor's body something fierce. To Trevor's disgust, Kyle was also leaking precum all over him, making him musky and sticky. Trevor had pulled the long straw and Josh was the short straw, but being just a smelly loincloth, he would have to dictate his change to Kyle to input it into the computer. The problem was that talking stimulated Kyle's cock, and he sure as hell didn't want a load of caveman spunk blown all over him. He sighed, knowing he would have to take his chances.
“Okay Josh”, Trevor began to speak, “I wish that your head ---“. Trevor was interrupted as Kyle began to let out a couple deep grunts. “Uh oh”, Trevor thought to himself as he felt Kyle’s cock twitch. Just then, a massive load of spunk rocketed out of Kyle’s hairy, footlong hunk of manhood. Kyle kept shooting load after load into Trevor the loincloth. All in all, it must have been a cup of seed that he shot out. The loads had splattered all over Trevor and were sticking to his body. Caveman spunk seemed to be different from human semen. Much to Trevor’s disgust, it was much more yellow and chunkier than human semen. It also was a lot stinkier and muskier, too.
“Gross Kyle!”, screamed Trevor. Kyle apologized in his deep, caveman voice, as he tried to scrape the cum off of his loincloth friend’s face.
After Trevor was somewhat cleaned off (he still stunk something fierce, though), he decided to continue with his change for Josh. “Josh, I wish that your head were conjoined onto Kyle’s stinky, Neanderthal body”. Josh eyes shot open in surprise; “What?!”.
Kyle grinned as he input the command into the chronivac. There was a flash and all that was left of the three boys was a Neanderthal with two heads, and a living loincloth. Josh’s head was on the right side of Kyle’s body. It was rather strange, having one head hairy and devolved, and the other head being that of a normal human.
“Gross!”, Josh began to yell as he ran his (Kyle’s) right hand through the musky, knotted rug on his chest, “Kyle this body is absolutely disgusting!”. He examined his body and grimaced at all the body hair he now possessed. “Man, Kyle, how do you stand it; we have as much body hair as a gorilla!”. Josh reaches into his loincloth and wraps his hand around his incredibly heavy, footlong piece of meat; “Alright, I guess this makes up for it a bit, I guess”, Josh jokes.
