I canceled class but didn't tell you, so it's just you and me today. Don't worry, it's not a bad thing, I just think you need to practice some self-control. Yeah, I've seen the way you stay in the back of the class and watch all the girls doing their poses. I see your cock throbbing in your shorts at the end of every class. You are in desperate need of some discipline and I'm going to make sure you get it. Now, sit down on your mat and take out your cock... ah ah ah! I didn't say stroke it. wow, you're going to take a lot of work... good thing we have all evening
