Change into some fitting clothes first

As he walked down the hall, Richard realized he could barely walk around in his old clothes anymore. He had become too buff, and too tall. So he thought of shrinking himself down a little before he could find some better clothes, but then he spotted Dave, one of his other bullies. He was sitting at a window in the hallway, talking to a beautiful blonde girl named Felicia.

'Hey there nerd!' Dave shouted when he spotted him, and Richard walked up to him with a confident smile.

'Come with me,' he commanded, and made him follow to an empty classroom, while Felicia stared at him in shock.

'What are you doing?!' she demanded. 'Do you let this creep just order you around?'

'Why not?' Dave answered, as if that was the furthest thing from his mind. When we were in the empty classroom, he sneered. 'Why did you want me here, creep? Want to suck my cock or something?'

'Take your clothes off, Dave,' Richard smirked. Dave's clothes would fit him a lot better now.

'I knew you were gay for me,' Dave laughed, but started undressing anyway. Richard did the same, then took his possessions out of his pocket and took Dave's clothes from him. As Richard started dressing up, Dave grabbed Richard's, but he stopped him.

'No, you will be stark naked today, and you will feel extremely embarrassed, but can do nothing about it.' Then he gave Dave's body another look, and saw that he was way too buff to be completely embarrassed. Worse, his cock was huge. So Richard transformed his cock into a micropenis, and gave him a lot of belly fat. He also made him a lot shorter, and gave him greasy hair on his head and between his legs. Then he made the bush so full that you could barely see his dick anymore.

In Dave's pocket he found his phone and wallet. He commanded Dave to tell him his phone password, then took $100 out of his wallet and left the classroom. He was shortly after followed by an extremely embarrassed Dave, who got laughed at by all his friends and a shocked Felicity the minute he stepped out. Richard continued to his class, smiling from ear to ear.
