Agumon opens the door to his cabin. He had just finished a rigorous training regimen and he was hungry and tired. His muscles ached somewhat, but it was a good type of pain, and his belly roared from hunger. He walks over to his pile of meat he got from the farmer and grabs 2 of them. He wasn't thirsty since he'd drunk a lot of water from the lake during his training, water that already felt like it was going to his bladder. He rubbed his midsection a bit. He devours the meat in a few bites, bone and all, and goes to his couch for a quick nap. He can totally hold that pee for a while.
 A few hours later, Agumon wakes to a belly cramp and a loud fart escaping from his ass. In fact, the fart was só loud, that he could have well awaken himself from that alone. He quickly tries to put his stubby tail between his legs. He had to go urgently. How did that happen? Was the flesh spoiled?
He runs through the door, towards the bathroom, letting out small toots along the way every three or four steps. Agumon hadn't take five steps out the door when he runs into a Goblimon.
"Hello, little Agumon. Something wrong?" The Goblimon smiles, acting oblivious to his problem.
"Nno. Of course not." Agumon could feel the pressure building behind his anus and in his bladder, while he tried to keep his cool.
He wasn't very good at holding anyway so he had to hurry.
"Can I go by please?" Agumon pleaded.
The Goblimon thinks for a minute before he steps out of the little dino's way. Agumon runs past, only for Goblimon to grab his tail and stop him. Agumon falls forward, landing on his belly and letting out a large toot. His poop blocked the rest of the gas from coming out. The muddy mass begin to force the anus open, but the panicked agumon quickly clenched up with all that he had.
"Hey, what are you...?"
Goblimon attemps to pull Agumon's tail from between his legs.
"Don't. Please." The little Agumon whimpers, preventing Goblimon for moving his tail.
"I didn't made you this way just to allow you to use the toilet."
Agumon was surprised by the statement. "What do you mean?"
"Simple. Me and the boys had a Impmon use his magic to make all the meat and mushrooms rotten so all the digimon except us would poop themselves silly." Goblimon laughs, using this opportunity to easily pull Agumon's tail from between his legs, showing off his ass and trembling anus.
Agumon struggles to keep the poop in without his tail but is able to keep his anus clenched. Keeping Agumon's tail flagged, The Goblimon rolls him onto his back, Agumon's erect cock now in full view, pulsing from sheer pressure. All that poop was pressing down on his prostate and the full bladder was doing the same thing. Never had agumon needed to go that badly. Goblimon slowly applies pressure to Agumon’s bladder, causing him to squirm. He hadn't had an accident in months and he didn't want to have one now, not after all the training. Unfortunately, his bladder was almost full and the pressure was unbearable. Goblimon pushes harder on Agumon’s bladder, causing him to gush out some clear water a bit.
"Stop. I can't hold for much longer!" Agumon squirms more, trying to get out from under Goblimon but the enemy is too heavy. Goblimon pushes on Agumon's bladder hard, causing him to start leaking more. Agumon felt like a bath toy full of water. Agumon tries to stop the stream but the floodgates had already been open. Golden pee starts to quickly spray from his cock onto the grass. Agumon's face turns bright red with embarrassment but Goblimon wasn't quite done yet. Goblimon, careful not to get peed on, starts to hold Agumon's butt open and watches Agumon's anus open and close. Without the tail and now unable to hold the tush clenched, Agumon could only count on his willpower to withstand the unsurmountable need to relieve his bowels. His tummy felt só full and painful, he could picture all that mushy mass fighting for space inside of him. More kept going, pushing the old stools against the sphincter. Agumon was breathing deeply and sweating cold.
Agumon watches in horror as Goblimon starts slowly widening his anus, causing him to turtlehead. Agumon tries to stop it but Goblimon continues to hold open his anus as the first turd starts to push itself out slowly. Agumon whimpers. "There we go. Come on." Goblimon said as the first turd lands in the puddle of pee followed by a second and third.
After a few minutes, Agumon finishes, leaving a huge pile of poop. He looks in embarrassment at it and starts crying.
"Welp, I'm going to find another victim." Goblimon disappears into the forest, leaving Agumon shaking and sobbing. He finally get a hold of himself. "I have to warn the others." He says, standing up and running toward the town.
