I can smell you so I know it's time to change your diaper. I get you all nice and fresh when I notice something. There is a bump in your diaper however it wasn't there before. I put my hand on it and immediately realise that someone has gotten very excited. You get embarrassed about it but, it's a perfectly normal thing. So normal in fact that I decided to show you how it's done. So you know the feelings you have are ok. I slip off my top showing you my breast. I think that made you even more excited by the feel of things. I rub you through your diaper and watch the pleasure on your face. It's ok to make cummies for step-mommy.
