Matt was trapped. Ben was hugging his frame quite tightly. Ben was so hairy and had incredibly bad body odor. Part of Matt was absolutely disgusted by this turn of events, and the other part of him was aroused. He knew if he gave into the latter half, he would spend the rest of his life as a hairy, stinky, knuckle dragging neanderthal.
Matt looked down at his body; he now had a very light smattering of chest hair, thick twisted bushes of pit hair that crept out with his arms at his side, and a thick treasure trail (glistening and a darker brown than his other body hair, thanks to Ben's caveman precum that had cultivated it. He knew that the hairy moist jungles that now resided under his arms were producing quite a stink, but nothing close to Ben's armpit odor. Uggh, Ben was absolutely disgusting, and Matt was becoming just like him. Matt grimaced as he felt his lightly hairy chest rub against Ben's incredibly thick, wiry, and sweaty chest hairs. "Maybe the sweat is speeding up the change", Matt thought to himself.
He was changing more and more, and his mind was becoming clouded; it was becoming harder to think. Was he getting stupider as he became more like a caveman? He had to act fast. Matt pushed against Ben with all his might. He arched his back, and grunted. His grunt scared Matt, as it was incredibly deep and animalistic. He could feel his thick adams apple bob up and down as he grunted. It was no use.
He relaxed again, and let his body go slack. Ben was too strong. He was destined to become a hairy, stink subhuman for the rest of his life. No more friends, school, travel, anything! His life would just include sniffing his hairy armpit, jacking off, and eating.
"NO! I am going to fight this!", Matt thought. He had an idea. He spied the thick twisted bush of pit hairs creeping out from under Ben's arms. God, his pits stunk. He was disgusted just by the thought, but he lowered his hands towards Ben's pits. Matt had just remembered that Ben was quite ticklish. He hope his new form was ticklish as well! He made contact with the sweat, thick hair. Gross. Caveman armpits! He pushed his fingers through the thick jungle. "This is so gross!", Matt thought. He could feel the hairs scrape past and get tangled up in his fingers. He could feel that his hand was now covered in sweat too. His hand firmly in Ben's pit, he started tickling.
Ben flinched almost immediately, and let go of Matt. Matt staggered away from his friend. He was covered in hair, sweat, and he stunk. He ran to the bathroom to look in the mirror and see the extent of the damages to his body!
