As Danny slowly came to, the first thing he noticed was it was very white and bright. He also noticed that he was lying on a smooth floor on his back. He could feel his thick back hair insulating himself from most of the cold tiles. He sat up with a start. "Back hair?" he thought confusedly as he reached behind to feel his back. Memories of what had happened came flooding back as his hard touched the thick curly dark crop of hair all over his back and shoulder. He groaned on a deep voice. He was a neanderthal now! And the devolver was nowhere to be found. Without that he couldn't change himself back ever again!
"Where the hell am I?", Danny tried to say but all that came out were grunts and ooks. Danny was terrified. If he had lost the ability to speak English how could he explain he wasn't really a hairy monstrous caveman!
He saw he was lying naked on the floor, but one part of his body wasn't lying down at all. Gazing past the nasty matted swirls of thick hair on his chest and stomach, he saw his thick leathery cock standing up rock hard and throbbing. His huge caveman balls ached and he was so horny! He hated his new body so much but he hated his cock even more! It was so big and smelly, and it was always leaking some fluid! It was covered in so much hair and thick leathery skin it looked more animal than man! Plus, he was horny all the time with it. Why was he stupid enough to change into a caveman! He could be stuck with that nasty cock forever! Not to mention the rest of this hairy beastly body. He lifted up his arm and took a sniff of his pit. It absolutely reeked and was a jungle of hair! His body was very nasty!
He sat up and saw there was a bed and a mirror in the room. He walked over to the mirror, and was startled by his beastly appearance; he still wasn't used to it. He could still see his handsome boyish face, but it was buried under protruding, bulging primitive bones and a whole lot of hair and dirt. He hadn't even shaved once ever before, and now he has a beard on his face! Not to mention a crazy unibrow as well!
He gasped when he saw his teeth were all crooked and a nasty yellow color! All that pain at the dentists and braces was evidently for nothing!
Just the door opened and in walked 2 scientists in lab coats, each holding various instruments...
