Tsk tsk! This is the second time I've had to change your diaper in an hour! You know I don't mind changing your diaper, but with the way you keep begging to be potty trained and wear grownup undies - it doesn't seem very likely at this rate! Let's put this to the test. I'm going to take this wet, pissy pull-up, wrap it around your hard little peepee, and if you manage NOT to cum all over it? Well, then, you'll prove you're a grownup! But we both know you're going to fail. You love the shameful squish of the wet diaper against your dick, especially with StepMommy guiding you in exactly how to stroke and counting you down! That's ok, you'll always be my special boy - so piss your fresh pull-up so we can play again!
