The teacher instructs the mice, dinosaurs along with Steve and Eric to go the toilet training room to help them out.
They are confronted with more teens, this time in pull-ups, along with their teacher.
"Oh good, the students from the health class are here."
"Mice, you'll lie down up on these tables, and the Barneys will strap you each down. All the Barney's, you can then lie down on the mats, the students in pull-ups will check each of your diapers and give you each an enema."
"If your diapers are already full, you'll be demoted to mice and will have to get on the table too."
"Once your all done, each of the dinos will choose a mouse to be their partner. You will stand in front of them."
On doing so, the students in the pull-ups then pull out big dildos and attach them onto the fronts of each of the dinosaur diapers.
The potties from from the first period with the toilet training students are bought behind each of them and connected by a tube to the dildos. The dinos are strapped into the back of the potty seat.
"Steve, Eric, you'll help with the training of the students this period."
"Dinos, you'll undo each of the mices diapers and move your dildo towards their hole. You'll each keep pumping them until you fill your own diaper. You may not make stickys while this is happening."
"Steve, Eric. You'll help pull down the students pull ups and sit them on the potties when they need to go. You'll then lick them clean and help them make milkies in your mouth."
The dinos move in position, before a machine starts pushing the pairs into each other. The mice all collectively moan as the first bit of mush is pushed into each of them.
The potties are each filled with two-three loads from the first period and they all keep pounding the mice.
Steve takes the first student in pull ups to one of the potties, pulls down their diaper and sits them on the throne. The student let's out a moan and pushes more mush into the already full potty.
The student stands up and turns around, presenting his ass to Steve to get cleaned. Steve obliges and starts licking away, he starts to get hard from the taste of the mess and starts to touch himself as he does.
Steve tells the student he is done cleaning, and they then turn around and push their cock into his waiting mouth and thrust until Steve gets a full load of the students milk as he rubs himself letting out his own load.
Eric repeats the process with another student, but abstains from making a mess of his own diaper.
Just as he finishes, one of the Barney's grunts from the enema and pushes a load into his diaper.
The Barney is then instructed to pull out and tape up the mices diaper.
The machine then lifts the Barney into the sky and over the face of the mouse. One of the training kids untapes the diaper and lets it fall onto the chest of the student. It then hovers the messy ass over the students mouth and the student is told to lick while the machine slides him back and fourth.
As it is happening, the training student inspects thr front for any sign of stickys.
Not finding any, the diaper is then taped onto the mouses head and a hole is pushed through giving access to their mouth, the Barney is then lowered onto them and begins to thrust into the mouse until he comes.
The mouse eventually releases the mess into the back of his own diaper, as others get the same treatment.
The ones that did make cummies in their diapers are instead given a pacifier linked to the back of the diapers of all the mice and tied to the potty seats.
