My master uses my underwear to gag me. I love it when I am tied up and gagged, and completley helpless. He call's this "play time" and I;m his favorite toy
Well said. Panties are an outstanding gag, especially if the crotch is placed in the right place! We've done this a lot too. I've also sometimes used thong panties as a more "full" gag, placing them in her mouth completely than taping over the lips - that produces some great mumbles!
Gagging is my ultimate fetish. Girls with ball-gags or tape gags are what I dream of. I love a girl moaning beneath a gag, maybe drooling from a ballgag.
What I dislike about gagging is that it prevents the sub from begging for leniency. Hearing the desperation in a sub's voice as he begs me to stop smacking his balls or working his nips is an amazing rush for me, because I can grant or deny the plea as it pleases me. I don't think you can get much more sense of power than that.
Gags are all kinds of fun, especially when its been decided that I've been a bit too mouthy during the scene and its time to shut me up. I'm usually gagged with my underwear too, but then I have to wear them again after we're done playing o_o
