Harold admired his monster self in the mirror, and mussed up his hair. "I look ferocious." He said to himself. He growls in satisfaction. He let out a roar. He sounded ferocious too.
Then, he looked at his clothes. Somehow or other, it seemed strange to be wearing clothes as a monster.
So on a whim, he removed his shirt and sweater vest, and stood, bare chested, in front of his mirror. His human chest seemed thin, yet out of place with monstrous features on his body.
Then, he unbelted his khakis, pulled them down, and stepped out of them, and stood in front of the mirror in his heart-patterned underwear.
"I look good." he said to himself - he was now a man with monster features in his underwear.
A quick dip of his hand down his underpants immediately met him with a startling discovery: His dick was much smaller, almost the size of his big toe!
"Wow!" he said. "I don't remember shrinkin' my willy."
He pulled his underwear down to expose his shrunken willy, and started to pull it. "It's amazin." he said. "I got a mini willy!"
