"I know you two enjoyed your pacifiers overnight but I think it's time to get some mileage out of those diapers"
"All that sticky goo is going to need to come out some how. So you'll be pooping the cum out until your diapers are filled."
They are each tied to a potty chair and a vibrator is positioned in front of them.
"No making stickies in the front of your diapers though. I'll be back to check on you in a bit."
Aidan begins to feel the rumble in his tummy and pushes out the first of the sticky mess into his back. The chairs detected it and Jeff's vibrator begins to start up.
Jeff moans at the pleasure from the vibrations but obeys Marks orders and begins to resist. The vibrations help move the goo through his bowels and he releases a load into the waiting diaper.
It causes Aidan's vibrator to also power up and Aidan jumps when it starts. He begins to succumb to the pleasent feeling, but then pushes out another load filling his diaper more so.
The feeling of an ever filling backside causes him to thrust into the diaper and waiting vibrations, while Jeff's vibrator incrases in power.
Jeff let's out his second filling while trying to tune out the vibrations, and Aidan's moves up to the next power level.
Aidan moans and begins bouncing more into the vibrator. He cant help it, he needs to release and he speeds up the bouncing.
Jeff then releases another load in the back causing Aidan's vibrator to go up another level. Aidan can't help but shoot the load covering the front in a sticky mess too.
Both vibrators suddenly stop.
They both push out one more load of cum into the waiting backs before Mark comes back in.
"Let's get you two off and check your diapers."
Mark brings Jeff onto the table and untapes his diaper. Mark smiles at the white slimy goo stringing away from his butt and coating the inside of the diaper.
He then turns to Aidan and does the same. He rubs his finger against the front, confirming that Aidan indeed did cum into the front.
"Mm.. I guess Aidan will need to be punished for this."
"Aidan, you'll..."
