Awesome story. I love how the Imposter stuffs the unconscious girl's panties in her mouth. Really sexy, hot, cruel and humiliating. I think Pantygags are really under used in USB stories. I've only used them a few times.
Here's that Page, were Comet steals a Female guard's uniform, ties her up and gages her with her own panties. The taunting from Comet is worth the whole thing.
