Today we're going to practice a little speed & endurance training. You'll watch me tease in my tight metallic dress as you stroke along to the pace of my metronome. Whatever tempo I set will determine the speed of your strokes. Faster and faster and then nice and slow, as I strip down to my bra and panties. The tempo will vary, my teasing will intensify, but you'll have to keep up no matter what. We're going to train that cock to obey. Can you keep up? If you lose control too soon, you'll have a punishment in store.
