Confession: I thought this was a romance going in, not erotica! It's a good read, but more sex than I expected. The protagonist, Suzanne, is into mommy/little girl domination as a sub. Her last domme messed her up, so she's got trust issues when she meets Pilar (Mami P) on kinklife. 

The plot of the book is the two of them working out Suzy's issues and falling in love. And doing a lot of fucking. It's a sweet story and an interesting look into a world other vanillas and I don't know about!
