I am reading a magazine when you walk in. I turn to tell you Mom and Dad are out shopping and notice you have a boner! You ask what a boner is and I begin to explain. I quickly realize you have no idea about masturbation. I feel sorry for you and decide to show you how it's done. I sit you down and have you get out your cock. I instruct you how to stroke it and ask you if you've ever seen a girl naked before. You confess you haven't and I strip for you, telling you it will help. Once I'm fully nude, I start to get turned on by watching you. I touch myself and show you how to touch a girl to make her feel really good. We cum together at the end and I tell you we better get cleaned up before our parents get home
