When he was asleep, Dustin had only sexual dreams. He saw himself as a huge man with a dick to match. He was such a strong, powerful man, that women made lines just to get fucked by him. He fucked woman after woman after woman, cumming in the real world, where the changes were still taking place.
Dustin woke up and felt like he had been buried alive. Something heavy was covering him, making him sink into the mattress.
When his eyes focused, he saw a gigantic hairy arm next to him. He jumped back, startled by the unexpected sight, and the arm drew back with him. It was his! He fell from his bed, and the ground shook.
"What happened to me!" he said, and his voice was extremely deep, and scared even him. Dustin looked down at his hands. They were too big and too hairy, belonging to a monster, like a wolfman. His body hair was thick and had grown on his hands, and his fingernails had grown slightly to short claws. He got up with a grunt and looked at himself in the mirror. He almost fainted when he saw the monster-man he had become. He had grown almost too much. He was at least seven feet tall, and more muscular than a pro bodybuilder. The pants had been torn at the seams by enormous quads, and the huge hockey jersey was tight against his powerful torso.
He walked closer to the mirror to inspect his face, and he was too tall so he had to squat a little to look at himself. His face had become animalistic and wild. His eyebrows were bushy, and met in the middle of a ridge of a brow. His facial hair was thick and long, like he had been growing a beard for years, and his hair was thick and very long, down to his giant back. He used his thick fingers to open his mouth and look at his teeth which felt weird. His four canines were slightly longer and sharper.
He still looked mostly human, but not like any human that had ever lived. He was too big and too strong. He smiled, showing his sharp canines, and was overcome with more sexual pleasure. He growled like a beast, looking at himself, making animalistic poses, showing his claws and his teeth, knowing he could tear anyone and anything apart with his strength and bestial features.
Dustin used his massive hairy hands to jack off his huge dick, and the pleasure became too much. He looked at the beastman vial. If this was what it had turned him into after just one quarter, what would he become if he drank the whole thing?
Dustin takes the vial and...
