You failed miserably with our last lesson so I am making sure I keep your COMPLETE attention tonight. I am naked so you are sure to sit up and concentrate on your lesson. Get on all 4's like a good little sissy slut, and arch that back! Let Mistress teach you how to move that sissy ass properly. I teach you the standard up and down motion - AND also an isolation move that teaches you to bounce each ass cheek separately. Now pay attention, slave. Learn your lesson.
