Cum Quietly for Step Daddy

So I must confess, I found this toy in the draw and I really want to try it out with you. I know what it's for which is why I am super excited to show you. I really want to be a good girl and cum for you step daddy but, I know I have to be quiet. I will try really hard not to be loud but, I can't make any promises. It just feels so good when I touch myself that I can't help but let out loud moans. When you stand there watching me I just lose myself. What is your baby girl supposed to do?
