Trying to find a story where Mom is a suburbam housewife who becomes a nympho

I remember reading this but cant find the story. Its about a repressed housewife who is investigating some porn shoot. She then gets persuaded to make some porn shoots. The story has around 15 parts. Her porn name is Susie Creampie. The sex life with her husband gets better but she also starts becoming sexual with her cousin who also becomes a porn star called Carlotta Cockslut
