Step-Mom left you in charge even though I am technically number one in her eyes and always will be. It gives her some strange comfort to know there is an older adult watching out for me. Speaking of watching, I need you to watch me stretch in my new tiny outfit. I bought this outfit to get the coach's attention next time I am in class. From the way you are staring at me right now I have an idea it's going to work exactly as I planned. You really are a pretty cool stepdad you know. I like that even though you're a macho tough guy you will do whatever women want you to. I am eighteen so I'm officially a grown woman. I want you to come over here and lie down on my bed. I want to be entertained. Show me your dick, step-daddy. Do you like it when I call you step-daddy, even thought you aren't my real step-dad? I can tell by the way your dick moved in your pants the moment I spread my perfect legs in that first stretch and asked you for your opinion.
