They bring each teen over except the winning one, lay them down and remove their diaper, before sliding another one under them, this new one has a hole with a valve in the backside.
They push a dildo into the hole of the teens and bring over the next ones, repeating until all 7 are hooked up.
The machine is then started and the dildos start pumping. The sticky liquid from the vat pushes it's way out into each of the teens assholes, until they are all filled.
The boys remove the dildos, tape up the teens in their clean diapers and get them seated in highchairs. There are holes for them to push a tube through to connect up to each of the valves of the diapers. They grab pacifiers with tubes coming out and push them into their mouths and tie them on.
The winning teen then grabs a cummy diaper which had been missed during the scraping, removes Marks current diaper and tapes him in the sticky one.
He then tells Mark to get Aidan ready for him. Mark brings Aidan over, untapes the teens diaper, positions Aidan on front of the teen and tapes him back up. He then grabs a spare pacifier and ties it into Aidan's mouth.
The teen then starts bouncing Aidan in his diaper getting him hard and pushing to fill Aidan's hole. The teen stands up and continues bouncing Aidan on him as the first of the teens in the highchair lets out a fart and pushes the first of their creamy mess into the pipes for all to feed on.
The first of the cummy feed enters Aidan's mouth as the teen shoots his seed into Aidan's backside.
The teen then lies down and motions for Mark to come over. The teen grabs him and starts rubbing his crotch through his diaper getting him hard before lifting him ontop of Aidans face.
The teen then starts rocking the pair causing Marks member to grow and throb against Aidan.
The rocking gets the teen hard again, filling Aidan's backside, and he continues to rock the pair harder until Mark shoots his load into the diaper and the teen shoots a second load into Aidan.
Another couple of teens then groan as they push out their first load into their diapers and down the feeding tubes. The cummy mess starts pumping into all of their mouths and keeps flowing.
The combination of the rocking, the feed and the penetration gets Aidan hard. Mark notices, sits on their crotch and bounces to stimulate Aidan, who's slurping down the cummy mess all while this happens.
It's not long before he shoots his own load into the front of the teens diaper.
The last 4 teens release their bowels into the waiting feeding tubes, and now they all begin to get a continuous feed, with no signs of slowing.
Now the floodgates are open, the teens continue to push out more sticky poopy loads into their diapers.
With the teen soft, Aidan has a chance to clear his bowels too, and poops his own sticky mess over the teen.
The teen, quite excited by this, asks Mark to help with Aidan.
He gets Mark to unbuckle the diaper, and remove Aidan's pacifier. The teen decides he wants a taste, and pops it in his own mouth whilst he lifts Aidan up and flips him around. Aidan's face is now positioned over the teens dick, and Mark tapes the diaper back up.
Aidan gets a big mouthful of all the cum he pooped out, and Mark is lifted onto the teens chest and told he can ride Aidan.
Mark gets behind Aidan, bends down and gives a couple of licks of their cummy mess, moves into position and starts to hump Aidan's sticky backside.
The gyrations get the teen hard, filling Aidan's mouth whilst Mark humps into his diaper.
The teen shoots his load down Aidan's throat causing him to cough some of it back up, whilst Mark shoots his own load into the diaper.
The teens diaper is then untaped again and Aidan is flipped back around to normal and his pacifier placed back.
Mark grabs a couple of wands out and tapes one to the front of the teens diaper, and one to his own and both are turned on.
The rest of the teens release the last of the mess into their diapers, ensuring there's still enough food for another 60 minutes of feeding.
The vibrators get to work, and both the teen and Mark enter a constant state of bliss. Within 5 minutes they both cant help but shoot load after load for the next half hour.
Aidan's tummy starts to groan from the pain of all the sticky goop filling him, whilst the front of marks diaper becomes a swimming pool of his own seed.
Mark then removes Aidan from the teens diaper, takes out the pacifier and removes his own diaper taping it on Aidan. Aidan poops out all the cummy mess filling him, leaving the diaper totally saturated.
The teen then asks Mark to put Aidan down the back side of his diaper, to which Mark obliges, pushing him in face first.
The teen lets out a fart and begins to fill the back of the diaper with poop, pushing some of it down Aidan's throat and the rest over his face.
Aidan is then removed, and the wand is taped to the front of his own diaper.
Mark then gets in the front of the teens diaper, and the teen begins rubbing the front getting Mark hard as he does, he shoots out a stream of pee, some of it shooting into Mark.
Mark shoots his seed into the front of the teens diaper as it expands from the pee to hug him.
Aidan also begins to shoot globs into the front of the very full diaper, causing it to start erupting out the waistband.
Mark is removed, and puts on a new diaper. He wipes down Aidan's face and they both get to work removing the rest of the teens from their chairs. They all have full diapers, so the two get to changing them all into fresh ones with no valve.
The one who avoided the highchair keeps his messy diaper as does Aidan.
