They decide to pull straws again and play another round. Trevor pulls the long one and Kyle pulls the short one, again. The boys stand there laughing at Kyle; "Man, you have the worst luck today, Kyle!", Josh laughs. For the next change, Trevor restores Kyle to human form, first. Trevor, typing, tells Kyle "well since you made me covered head to toe in body hair, I have to pay you back by going one step further!". Just as he finished saying that, Trevor let out a little involuntary fart; with his nose right above his asshole, Trevor couldn't help but sniff it. Josh and Kyle laugh hysterically as Trevor turns a shade of green. He still is disgusted by the smell, but he had to admit, he was slowly getting used to it and breathing through his nose every once in a while.
As Trevor hits enter, Kyle's whole body began to itch, much like Trevor's change. "Enjoy being a stinky, dirty neanderthal, my friend!", Trevor states to Kyle, who's eyes grow wide with surprise. Kyle begins scratching madly to alleviate the itch as thick brown body hair sprouts out of nearly every pore. Kyle's leg hairs grow very thick and tangle together. The change hits his crotch, hard. He struggles to take off his boxers as his cock grows exponentially, becoming a thick hairy hose covered in veins. It also grew a thick leathery covering over the cock, making it look a bit like an animal dick. His balls swelled and sagged as his pubic bush erupted, twisting and matting together, creating a dirty tangled "loincloth" of hair. By now, Kyle's arms have grown way longer than they should be while his legs seem to be shrinking in length. His enlarged, hairy hands hang down to his knees now (as does his new beastial cock). Hair races up his torso, front and back, creating thick, dirty tufts of body hair. His armpits, already having been pretty hairy, exploded with hair. The thick wiry hair twisted into a ridiculously sized bush. The last place to change was Kyle's face; a thick beard poured out of his pores and his adams apple grew and stuck out noticeably. Kyle grunted in an incredibly deep voice, and as he did so, the boys watched his thick adams apple bobbing up and down. A unibrow spouts out of his face as his brow bulged outwards with a new bony protrusion.
Standing there naked was a neanderthal Kyle; hunched, hairy, and hung. "Whoa dude, he looks like an animal. Can you talk, Kyle?", Josh asks. "I talk but it hard make words", Kyle dumbly replies in a deep, gruff voice as he absentmindedly scratches his fingers through his tangled, thick armpit hair. "Haha, great idea Trevor! This is too funny!", Josh says excitedly as they watch Kyle explore his new body. As they do this, though, Josh notices a consequence of the new change; Kyle stunk horribly! His matted pubic bush and hairy ass were exuding a musky, sweaty body odor, while his hairy armpits stunk like a condensed version of the entire football locker room. It made sense; a neanderthal would never have had a chance to shower or use soap. "dude, Kyle, you fucking reek! Your stinking up the whole room!". Kyle lifts up his arm and buries his nose in his tuft of pit hair; "Mmmm Kyle like smell".
Trevor was unaware of Kyle's stench, as his nose was too busy with his asshole. "Yea Trevor, I don't know what would be worse; sniffing an asshole all day or having to smell Kyle's caveman body odor!", Josh jokes with Trevor. They hear a grunt and they both glance over at Kyle, who is slowly stroking his new cock. "Hey, caveman Kyle, stop jacking it and come do another round of straws!", bellowed Josh. Kyle wheeled around with a completely vacant, dull look in his eyes; "but it make feel good!", Kyle grunts out with much effort. Josh and Trevor laugh as Josh picks up the three straws in their hands to play again.
