Madison was really excited. She had infinite money and complete control over her annoying little brother. However, she lacked ideas and she quickly got bored. At first, it was fun to transform Ryan but he was acting like a robot so he didn't react or felt anything. She wanted to humiliate him, to make him suffer as a punishment for forcing to watch him during vacation.
“You are going to be conscious but I'm going to keep my total control over you. You can't escape, hurt me or take the collar out of your neck, no matter how badly you wanted it.” Madison said and almost immediately Ryan started to react like he was getting free from a trance.
“Maddy? What happened? I don't remember anything.” Ryan said as he recovered his senses. “My head is spinning.”
“Not much, just I got complete control over you. Literally.” Madison replied. “You were calling me master and obeying every command I gave to you but it wasn't fun with you acting like a robot. So, I gave your consciousness back. You can still call me master because you're now my slave.”
“Haha, how funny.” Ryan sarcastically said. “I won't call you master and I don't believe you have control over me. So, excuse me, but I'm going to play some video games.”
Ryan tried to walk away but he soon realized he couldn't. His feet weren't moving like if they're numb or glued to the carpet.
“l told you.” Madison grinned. “You can't leave unless I say so. Now, it's time for my revenge. First, take off your shirt, pants and shoes.”
“Please Maddy! No.” Ryan begged as he useless try to don't undress but his hands were moving against his will. He took his shoes off, then his shirt and finally his pants. His pale skin was getting cold as he felt so exposed in front of his sister. At least, he was glad that he's still wearing his briefs.
“Ok, now let's go outside.” Maddy smiled. “Let's show your pathetic body to the world.” She opened the main door and came out. Ryan didn't want to but he sheepishly followed her as he tried to cover his tiny boyhood with his hands.
“Why are you covering it? That's too small that no one can see it. Maybe I should make it bigger to make it more humiliating...” She grinned as she watched Ryan's briefs stretching by the growing bulge in them. He was reddening in shame. “Or, even better, I should make YOU bigger to humiliate you more. People will be more scandalized to see a naked man than a naked boy.”
After hearing that, Ryan was completely terrified but he knew he can't do anything when he started to feel the changes. He grunted and groaned loudly, squirming and holding his tummy. He groaned again, then his eyes widened as he belched, it sounded disgusting that some people gave disapproval stares to him.
Then, his whole body started to pop and creak. making odd squelching noises as his feet snapped, grew, and shredded his now small socks. He was yelping and screaming inside in horror as his body was thrust through a brutal growth spurt, lengthening, widening, becoming tall and lanky, then filling in with naturally fit muscle.
Suddenly he started to sweat, as bodyhair started to fill over his legs, up his thighs, into his now too small briefs, then up his abs and his chest. He was getting really itchy that he shamefully started to scratch desperately at it while a pelt of hair grew in and dampened.
Finally after a desperate whimpering groan, he started to cry which looked pathetic coming from a man like him. He now was a 6'1" tall, well built and furry young man. His tiny briefs were his only clothes left on him but they were so small that wearing them was even more humiliating.
“Hahaha, you don't look bad but I'm not making you a favor.” Madison said. “So, to emphasize your shameful maleness you're going to be hard for the rest of the day.”
“H-hard?” Ryan stuttered with his new deeper voice. He didn't understand his sister words until he started to feel a very odd and kinda pleasant feeling in his crotch. His already big dick was getting bigger and hard like his sister said. Unfortunately, his briefs weren't big enough but they weren't giving up at the same time, so he was getting a very uncomfortable wedgie. He didn't know if he preferred that or being naked.
“Ok, now we're ready for a walk.” Madison started to move followed by an ashamed Ryan who was pathetically trying to hide his boner behind his hairy hands. “Let's think. Where can we go to humiliate you even more?”
