Chris hissed "Disobey me and I will rip you limb from limb!"
"Holy shit.." whispered Ty and Chris could see the horror he was imposing into him. It made him wish for more power and more strength. Seeing Ty so afraid of him made him even harder.
"give....ME......MOOOOORRRRE!" Chris roared, grabbing Ty with just one hand, threatening to crush him.
Ty screamed and then everything went quiet. Chris felt something go into him, like a spirit. Like Ty had cast another spell on him. Chris losened the grip of his giant hand and took a step back and then stopped,silent, looking into space. What had ty done to him?
Then came the first signs of a new change.
"Moooreee..." he hissed and began to feel his body convulse. He was losing all control. He twitched and with every twitch came a guttural snarls and new changes, further turning him into a true monster totally drunk with power. Chris bent over and his back began to grow even wider. His feet exploded with size, toes becoming thick and wide. He took one step and the sudden growth of his right arm into a tree-sized monstrosity made him stumble. He was almost quick enough to lean against a wall but his arm was too powerfull. he crashed through the wall and fell into the yard, becoming more and more gigantic.
The changes accelerated with one loud roar and he stood up. He was almost as tall as the second floor of the house. His legs were long but extremely thick. His arms had grown ridiculously thick and long, hairy in the forearms and hands and knuckles, like a caveman. His stomach distended creating a fuzzy muscle gut that only made him look stronger. Even in this stupified state, Chris knew he had attained the power he lusted for. He laughed like a cartoon villain but then noticed that the changes weren't stopping...!
"Huh?" he heard himself say in a new voice.
Every feet he grew, every half a ton of muscle and bone and hair that was piling on his already giant body was giving him pain. He screamed again, flexing his still growing muscles not to show them off but because they were putting pressure on him. He began to grow as scared as he was growing big, and aroused. Chris' face was going numb and he saw on the window's reflection that he was becoming a proper monster. His eyes were glowing red like fire. He had grown horns and his teeth had grown massive tusks that didn't fit in his mouth.
Chris pumped higher and higher until he was taller than the house. The changes were finally done and he could hear people scream around him. Chris turned and looked down at the people that were barely as tall as his gigantic clawed feet. He let out a roar so loud it set off car alarms, made people faint and pee their pants. He couldn't really process the fact that he had become a giant man beast who wanted to dominate and destroy and fuck, and seeing those people fear him made him hard.
"I AM YOUR NEW OVERLORRRD!" Chris growled. "I AM THE BIGGEST AND STRONGEST THING THERE IS!!"
His dick almost hurt him and he just wanted to put it somewhere...
