A ring gag

You find your ring gag. The simple ring is silver, with a single leather strap to hold it in peoples mouths. You always loved these as they made people unable to stop their drooling, and the possibilities they opened...

Your Slut giggles when you strap it into her mouth, no doubt aware that she now can´t resist giving you a blowjob anytime you want. Already, drool is running down her chin and dripping onto the floor.

What will you do?
