Hello everyone! My boyfriend is a DL and introduced me to this kink a bit ago. I am extremely maternal and LOVE the idea of being his "mommy" in the bedroom, but I just have a few questions. What are some things I can do as the "mommy"? What kind of things would be a turn on? What kind of dirty talk could I use? He has mention wanting diaper punishment, though more for the actual wearing rather than using them to pee or poo. He also likes the idea of being called a "spoiled little girl".
