I ask you to grab something from the top shelf for me and as I reach up, I accidentally flash you! Oh my goodness, I'm so sorry! I'm your StepMum, you shouldn't be seeing my breasts like that. I look down and I'm shocked to see that you have a hard-on. We have to do something to take care of it... I know that I'm your StepMother, but maybe I can give you a hand? Erm... I mean... some encouragement? I tell you step by step exactly what to do with your cock for your StepMum
