I am your girlfriend and I have really been enjoying our naughty roleplays lately, and I think it's time to take it a step further. I have bought you a full size adult diaper, I call it a nappy as I am British! I present you with your nappy and at first you are worried, but I tell you how much it would turn me on if you wore it under your trousers when we were out in public. And when we are at home you can completely succumb to me as your mummy, you can and pee in your nappy and i will change you and clean you up and care for you just like you were my own baby boy! It's time to take our mummy baby play to the next level!
