Mama had been making you tell her whenever you were going to use your diaper. At first it was humiliating, making you squat down and use your diapers in front of her while she coos praises to you. But the embarrassment left you weeks ago, it almost feels like a chore at this point. You never really understood why, but after she praises you for filling your diapers, you would hear it.
Not too loud, but enough to be noticeable every time, coming from a little black button Mama wears around her wrist.
The innocent sound started to work its way into your brain, now you expect to hear it any time you use your diapers.
As you have many times before, you go to Mama to use your diapers. "Mama, I hafta-"
In an instant your head is flooded with dopamine and your bladder lets go entirely despite your best efforts to make it stop. Mama lets out a satisfied hum as she watches the wetness indicator between your legs turn blue. All you can do is whimper as she showers you in more praise than ever~~
