Jimmy was in the kitchen with a rubber blue bunny hot water bottle filled with ice. He had it resting on his wrist. As he walked back from the kitchen into the living room, his buddy Bizz entered.
"Hey, Bizz," said Jimmy thoughtfully. He glanced from Bizz to the computer on his desk. "Have a seat."
Jimmy sat down with the screen between him and Bizz. He glanced at the screen. There were now two windows with naked men displayed. "Subject One" was Jimmy. "Subject Two" was Bizz. Jimmy pursed his lips.
"So, you want me to draw you as a pair of underwear, Bizz?"
"Really, a gif of me shrinking into a pair of shiny trunks would be great," Bizz said eagerly sitting forward in his seat and rubbing his hands.
Jimmy chuckled at Bizz's fantasy, and clicked on the inanimate options for subject 2. He clicked on the unaware option, and grinned as Bizz's clothing vanished. His body disappeared quickly, and his skin flushed into a shiny metallic silver. Jimmy fiddled with the screen using his stylus to make his crotch bigger or tighter. He spun the image around on the screen, and looked at the butt. Smooth or hugging? Or maybe open?
Ten minutes later, Jimmy was standing in front of a mirror holding a shiny pair of silver trunks in front of him. Bizz's face was clearly visible on the empty pouch.
"C'mon, Jimmy, please put me on, already!" begged Bizz eagerly.
Jimmy snickered. Bizz was unaware that he was ever human, he thought he was living underwear. He lived to be worn. Jimmy stepped into his new shiny trunks and pulled them up. He did a model twirl and laughed. Bizz was the most comfortable pair of undies that he'd ever worn.
