I'm trying to explain the facts of life to you, but you're more than a little confused. you seem to be unable to grasp the concept of fellatio so I try explaining it and helping you understand it. Obviously you will hopefully need to know all of this and I want you to be prepared when the time comes. After all, I'm your step-mother and I love you and it's my responsibility to make sure you're ready for life. I keep trying to explain things to you, but I think the only way to make sure you get it is to just show you what I'm talking about. After all, a demonstration can be really helpful when teaching and you've always been a kinesthetic learner. Don't be nervous, it's ok because it's just for educational purposes. Let me teach you what a "blowjob" is!
