Let this training remind you of exactly where you belong. Beneath me. You love being my object. My little puppy. My toy. Tormented by the sounds of my pleasure, all you can do is strain. Strain to see me through the bars of your prison, to see the way I wriggle in pleasure while I hold this vibrator against my nylon-encased pussy. Strain as you use all your energy to listen to my moans, imagining the shapes my mouth is making. All you can do is ACHE. Against the tight chastity cage that all good objects must wear. Pent up, with so much denied energy. In those brief moments of release, when you're finally wanted, you'll focus so attentively on pleasing me. Performing each task I give you with your highest effort. No matter how humiliating.
