You are humming along with the radio as you start to feel a pleasant warming sensation on your crotch, you sighs as it feels so good but other than that you just go about what you were doing.
It's about ten moments latter that your little sister looks over to your diaper's wetness indicator, "Um... Ashley you're wet..." she says wondering if you even noticed. You scoff, honestly she couldn't possibly be right you didn't even feel the need to pee, "No I'm not you silly!" You say as your mother reaches around to check you.
"A bit wet but the diaper can hold a bit more..." she says monotone and dead. You freeze and start to look down. You didn't even feel the need why are you so bad at this now?
