The bin is bought to a room and left in a corner.
There are 4 teens in the room, the first is strapped to a table in a diaper, with a dildo thrusting in and out his mouth, with cum dribbling down his cheeks and pooling on the table. A wand is locked in place in front of his crotch and is pulsing and whirring away, causing him to moan and grind into it. A couple of minutes of grinding later and he shoots a load into the diaper.
The dildo thrusting into his mouth responds and speeds up and fills his mouth with a massive load of cum every thrust, it's going too fast for him to try and swallow it, causing it to erupt all over his face and table. Finally it pauses, and pushes itself down the back of his throat, and pumps cum directly down his throat and into his stomach.
Finally it retracts, with the tip just far enough in to keep his mouth open.
The wand starts up again, and begins to stimulate him, he thrusts into his diaper and is quickly able to shoot his load.
This time the dildo starts pushing out mushy poop into his mouth which he swallows down
He has been on the table for the last 8 hours, the machines keep feeding him and stimulating him, the cum and shit feeding quickly gets absorbed to fill his balls ensuring he keeps shooting his own massive loads into the diaper upto 10 times an hour.
The diaper is almost completly soaked purely with the cum he has been made to shoot out. It is removed from him, weighed and set aside.
The boys hands are restrained and the diaper Mark is in gets slid under the boy while another dildo pushes into his butt and begins to pump cum into his back. The dildo in his mouth also starts back up and begins pumping more cum for him to swallow. Both of them keep pumping and thrusting into the boy squirting out load after load inside him. The one going into his butt pushes a little deeper with every thrust, pushing the previously pumped cum deep inside him. It pauses every 5 minutes and swaps out for a slightly girthier dildo. While the mouth one is taking it easy and feeding him amounts he can easily swallow down and not going too extreme. The feeding makes him horny having not shot a load for a while, but with the restraints and open diaper, he is unable to stimulate himself and just struggles with his dick standing strong.
The dildo violating his ass hole finally stops after 30 minutes once it has pushed half the weight of the old diaper worth of cum into him. A plug gets inserted ensuring the cum filling his butt stays there. The diaper is closed up, bringing Mark face to face with the boys dick.
The boys hands are unrestrained, and his old cum filled diaper is placed around his face, the cock violating his face retreats and the diaper closed.
Finally the boy is able to start to rub himself, grinding Mark and the clean diaper up and down his shaft. The machine copies his movements, but rubs the cum filled diaper into his face squeezing the sticky goop everywhere.
The boy keeps going, not fussed by the machine violating his face the same way he is unintentionally violating Mark.
After a few minutes, he finally releases his built up load, covering Mark in his sticky seed. The machine mirrors this too and pushes the dildo between his chin and the face diaper and starts unloading it's load all over his face. So much shoots out it causes the diaper to balloon before it all leaking out down the sides of his face and all over the table and underside of the diaper.
The diaper around his face is opened back up, showing the thick sticky mess covering every inch of his face.
The dildo pushes it's way back into the boys mouth and it begins pushing more poopy mess down his throat, switching every minute to shoot a bit of piss too to wash the poop down.
The mushy feeding causes him to stand to attention again, and pushes up against Mark who starts squirming under the pressure. The boy feeling the squirms goes to rub the front of the diaper pushing Mark around. The wand comes back and takes over from the boys hand.
The boy makes quick use of the toy as it presented itself, feeding into the vibrations the boy thrusts himself against the front of the diaper and shoots his load saturating Mark for the 2nd time.
The machine then pulls the wand back away and opens up the boys diaper and cuts open the pocket Mark is trapped in, pulling him out. In the process it restrains the boys arms again and moves in to remove the plug in his ass. It quickly pushes Mark into the boys hole foot first followed by the dildo which shots a little more cum in pushing mark down inside.
Finally it pushes a cathader down into his balls and begins pumping his balls more full of cum then they ever have been.
To bring the boy to climax, the machine brings over a
