I squatted down on my hands and knees, a thin sheen of sweat on my forehead. I had been holding it for hours, waiting until I couldn't anymore. And the buzzing vibrator deep between my legs had whirled me into a frenzy. Finally, it was time. I pushed and grunted and forced the massive mess into my diaper, as the vibrator brought me to orgasm.

"Mom?"
Click. My Mom looked up right as my camera clicked. We were close enough, and I didn't have any want to humiliate her, but gosh if this wasn't an absolute kodak moment. I couldn't help but laugh.
"Mom what the fuck are you doing, oh my god."
Then. Then the smell hit me.

I looked up at Allison and fumbled to my feet. But that wasn't any better: the front of my very wet diaper on full display, and the heavy load weighing down my diaper between my legs. Then the vibrator made me stumble. I held the wall for support and tried to pull my shirt down to hide my shame.
"A-Allison! I... y-you're not supposed to be home this weekend!" She stayed at college to study. She told me herself!
~~~
"And you're not supposed to be an incontinent grandma crouching around like a creeper!"
I coughed and sputtered, and then I heard it. The buzzing. The vibrating coming from my Mom. It took a second for the penny to drop.
"Oh my god, Mom, you're getting off on this. Oh my god."
~~~
"I..." My cheeks filled with a deep red blush, and that was all he confirmation Allison needed. She was never supposed to find out about this! I shook my head and put on my best Mom Voice. "G-go to your room this moment! We will talk about it later!" But a stinky diaper really diluted my efforts.

"Oh I don't know about that, Mom. You kind of lost the ability to send me to my room the day I turned 18, and now that I know you're a pervert... well, we're gonna have a long talk about the rules you try to set about me not bringing my partners home, huh?"
Wow. She really was almost as much of a pervert as me, wasn't she? My Mom. The apple didn't really fall far from the tree.
"I'm gonna let you finish up and go get cleaned up, then we have a real big talk to have."
