Matt once he spotted his sister tried to smack Bens veiny musclar arm away from its grasp. He let loose an utteral growl from his center of humanity that frightened the other two girls to run off.
Larry by now was sleeping because he was exhausted from the high intensity sex he was having with Ben. Ben acknowledged his friends feelings and ran off towards the other girls.
Julia then tried communicating to the muscular naked man, "You-You saved my life"
"Not much" Matt spoke
Amazed by this Julia tried more communication,
"What's that other creatures name?"
"Name Ben"
Amazed by the response she continued,
"And whose that on the ground?"
"Him name Larry"
Feeling more comfortable she asked him:
"What's your name?"
"Matt an you is sister" Matt cried out in as much proper English he could remember and Julia instantly cried and hugged her older brother.
"Well you grew" she sniffled, "I have to ask you, because mom and dad are going to want to know, how did you do that?" Unbeknownst to Julia Matt was starting to become horny too and started to excrete sweat and body odor.
"Me got this way by Ben"
"So why-woah" Julia jumped as she got a sudden headache
"That's weird," she looked down to her hands "I don't remember them being this big. Suddenly she gasped as her shirt began tearing to the muscle mass she was swelling with.
"Wha-at is happening to me?" Her shirt was now gone and all that was left was her bra. Her legs at this point also tore themselves out of their restraints and started covering up her legs and abs with more hair.
Matt started to cum at the idea of a cavewoman as Julia's language started to devolve. "Why am me talks like this?" She complained as she cupped her head with her massive hands. Suddenly Julia climaxed in her devolution and all that was left was a tiny bra and panty covering 1/15 of what it had originally. Additionally Julia started to let out her own juices and body odor growing nasty breath and smelly armpits.
Once she put down her hands she was through with 96% of the devolution. She turned to Matt with a sudden lust and instantly her breasts swell even more and are covered with even more body hair. Her eyebrows became as bushy and a unibrow as Matts were. Her ass swelled with muscle and hair snapping the worn out panty and dripping with her own fluids.
"Me am Julia now"
"Me want Julia" Matt said totally devoid of his humanity
"Julia play hard to get" Julia replied in as just broken English as Matt had originally
"Me like you lots" Matt responded
And no more was said except for groans, moans, and grunts as Julia jumped onto his muscles penis and went to town nearby the river.
Meanwhile out in the woods Heather and Katie ran and hid somewhere under a tree. Ben knowing where they were from the beginning decides to wait and transform them when he deemed proper.
"Where'd he go?" Heather asked worried
"He? Do you really think that thing is even human?" Katie replied just as scared
"Well it had a penis. It's really hard to miss that y'know"
"Well whatever it is we can't let it find us"
-A tree collapses in the distance-
The two both scream and cover each other's mouths to prevent the either from giving away their position. Out of the woods came two hunks covered in white fluid and incredibly sweaty. Matt and Julia then saw Ben and examined the situation and began a hunt for sex.
Matt and Ben scared the girls out of their hiding spots and then the girls ran for their lives. They were so terrified while running they never looked forward and ran straight into Julia.
"You am puny, but me strong" she said as she picked them up.
"AAAAAHHH!" The girls screamed
Annoyed by their screaming Julia shoved them into her chest and armpit hair.
"That teach not make loud-loud"
Both girls were now spitting hair from their mouths as the changes came to them. Julia noticing their change put them down on the ground.
"Serves you right to big smelly odorous beast" Katie shouted
"But we am friends" Julia whined
"How could we be friends with- Heather where are you going?!" Heather headed towards the pond nearby and fell holding her sides
"Heather? Heather?!" Katie screamed, "You, you did this!" She pointed to Heather
"Me am trying to help you" Julia said
"Me am Julia" Now it hit Katie that this was Julia and hugged and cried on her shoulder;
"What happened girl? What happened to-"
Thunderous footsteps were heard in the distance as Matt, Ben, and Larry, fully conscious, were coming.
"What are they doing here?" Katie shouted and pointed
"They am here for pounding" Julia said as she went off to join Matt getting fucked by Ben and Larry.
"Oh Julia what happened to you, what happened to this town?" All of a sudden Heather started to get up, but with every struggle her muscles grew. By the time she was at a push-up position her breasts and body were covered with an overgrowth of hair. Her ass was as muscular as Julia's was and her eyebrows were starting to merge like Julias did.
Katie ran over to Heather and screamed what was happening to her but before she could finish she was finding it hard to put together sentences. She glanced at the waters reflection and saw she had already grown a unibrow.
