Stuff them in her mouth.

You open up the barwench's mouth and gag her with her own red panties.They bunch up nice and easily, sliding into her mouth as if they belong there. You fix them in place with a scrap of somebody's stocking, tied around her head. You have a sense that being **** to taste the silk of her own underwear is going to infuriate her, which of course makes it all the more fun for you.

So much for that. Now for a few finishing touches.
