StepMommy is having a lay down on her bed when you walk in. I ask what you are doing in here and you smile at me, watching me with a different kind of look on your face. I notice that you have a hard on and I ask if I caused this. Don't worry - StepMommy has lots of new curves recently and it's very normal to feel this way. Since StepMommy caused this, StepMommy will help you to solve it. I strip out of my dress and panties and tell you to strip too. I wrap my hand around you... "just relax darling, good boy... StepMommy will help you stroke it."
