Dr. Kling was adjusting his new underwear when a new volunteer arrived in the room. It was another young man, blonde, tall and well toned.
"Hi, I'm here for the work." The young man said. "My name is David."
"Hi, David. I'm the dr. Kling but you can call me Calvin. Tell me a little about you. What bring you here?"
"Money, of course." David said. "I heard I could get easy money in here."
"Yes, you can." Dr. Kling replied. "Ok, then. You'll be part of my experiment. The amount of money you'll get depends on the results."
"And, how do I give you the best results?"
"You don't have to do nothing. Only stay there." Dr. Kling shot David like he did with Rusty. The young man immediately began to deflate like a balloon. He tried to run away but his legs were now as thin as paper. "You won't need those clothes anymore. Let's take them off!"
Dr. Kling started to strip David who can't do anything but trying to protest. However, his vocal chords had flattened already and he was almost mute by now. He can't move his head but he could feel Dr. Kling's hand through his flat body taking his shirt off, then his pants and finally his underwear. David was desperately trying to scream when he felt his naked flat butt touching the cold tiles.
"You're a big boy, David." Dr. Kling said as he used his special adhesive to bind David's left arm to his left leg and his right arm to his right leg. "You will be a great underwear for other big size boys."
When dr. Kling was done with David, he smiled and moved the human underwear to a table, then he sprayed him with a special chemical and David began to shrink. He shrank to underwear size but he was definitely bigger than Rusty with a bigger pouch than him to hold a bigger junk, his cock and balls were hanging in front while his head was hanging in back.
"Now, you just need a wearer." Dr. Kling grinned. "Your experiment won't be evaluated until then."
