Dean looked over at Charlie and then grimaced.
"Sorry Charlie. I'll come back for you." he said before running away. Charlie looked in shock to see his friend leave him.
"Dean! No Dean don't leave me!"
"What a shame." the old lade said before taking Charlie to a private room. She had down on a chair and pulled a spoon out her sleeve. She poured something into the spoon and then fed it to Charlie. Instantly he started to feel funny. Like his entire body was straining. And then he started to grow. He grew up the ten inch size back to his normal 5'10 height. The ropes grew with him, keeping him bound.
"I'm normal."
"Not quite."
Charlie tried to get up, but found that he couldn't move his torso. He tried to struggle against his bounds, but it was useless. He knew he was stronger than string. The old lady walked over to him and grabbed him by his cock. He yelped in surprise and had to follow her to another room.
She took him to a strange machine and strapped him to it. He felt something cram into his ass and he gasped. "What are you-oh...oh...."
The butt plug began to vibrate and he felt a weird feeling. His skinny body started to get pumped. He was growing muscles. His pecs grew, biceps hardened, and his flat stomach became a hard six pack. He no longer looked like a puny sixteen year old, but a strong, handsome 20 year old model. Even his cock had grew.
But it didn't matter to Charlie. The vibration was soooo good it seemed nothing in the world matter. His eyes fogged over and he stared dumbly in front of him. The old lady smiled. Charlie was now her mind slave.
