"I know where your eyes were during the last part and they weren't looking at my face. I know you were looking at my ass. I can understand that as my ass is irresistable but I like my slaves to have a bit more self-disipline so for the next 100, keep your eyes firmly focussed on my eyes. If you happen to glance anywhere else, you must give yourself a big hit to the balls and start from 0 again."
