"Terriermon!" It was a common sound around the apartment now -- this was the second day the problem had been going on. Terriermon had always been good about taking his business outside, but for the last two days, Henry had been finding digi-poop laying right in the middle of his bedroom floor.
     "But Henry!" Terriermon protested. "I was with you for almost the entire day! How could I have done that, you know I would never..."
     "Well, you have for the last two days," Henry interrupted, scolding. "I mean, I know accidents happen, Terriermon, but you don't have to lie to me about it!"
     "But... but..."
     "No buts! If you can't control yourself, I think we're just going to have to do something drastic about the situation!" Henry marched out of the room, digging in the hallway closet, and came back with a diaper. Terriermon's ears drooped even further than they were already.
     "Aw, come on, Henry! You're not gonna make me wear that stupid thing, are you?!"
     "As long as you're going to be a baby about going to the bathroom on my floor and lying to me about it, yes! I'd better not catch you out of that diaper, Terriermon! I've got to head out to pick some stuff up, and I'll be back in a while. And if you go on my floor again..." Henry decided to leave what he'd do to Terriermon up to his imagination, and grabbed his backpack, heading out the door.

     Almost as soon as Henry closed the door, Terriermon heard an all-too-familiar, snide laugh. It didn't take much thought to figure out who it was.
     "Impmon! Get your good for nothing tail in here!" Impmon, still laughing, hopped in through the window, laughing even harder at the sight of Terriermon standing there in a diaper.
     "Oh, this is rich! Hey, longears, what's with the new accessory? Hoping it'll make your ass look as big as your ears?"
     "Shut up, Impmon!" Terriermon growled. "I should have known you were involved somehow. What the hell's your problem, anyway?!" Impmon just grinned.
     "My problem? I'm not the one who can't control where and when I take a shit. Or should I say I'm not the sap who gets blamed for it!" Terriermon growled, and as Impmon doubled over in laughter, Terriermon ripped off his diaper, tossing it as hard as he could at Impmon, diving at Impmon in a fury as soon as he threw the diaper. The diaper smacked Impmon in the head, and while it didn't hurt, he looked up just in time to see Terriermon tackle him, wrestling him to the floor. Terriermon was small, but was considerably stronger than he looked, and it took no time at all to pin Impmon to the floor.

     Impmon growled, struggling to get up from under the green furry digimon. He found, however, he was completely unable to get up. He looked at Terriermon, who just grinned.
     "What the hell are you doing? Get off of me!" Impmon shouted.
     "Not until I show you who the one with the problem is!" Terriermon said with an almost evil grin. His small cock began to poke out of its sheath, spraying Impmon in the face as he relieved his bladder, pissing all over him. Impmon gagged and sputtered, struggling even harder to get up.
     "You sick freak, stop it! Let me go!"
     "Oh, but now it looks like you're full of pee, Impmon, and we all know there's only two things which hold pee. One is a toilet, but that's too good for you..." Terriermon got up, and Impmon jumped to his feet, trying to shake himself dry. He was surprised to find, however, that Terriermon's piss seemed to almost cling to him.
     "What the hell?! What did you do to me?!" Terriermon just stood there, grinning. "I said what the hell did you do to me, you long-eared bastard?!" Terriermon just walked away, going into the bathroom and coming back with a bottle of baby powder, opening it and sprinkling some all over Impmon's face, chest, crotch, and the front of his legs. Impmon began coughing, trying to remove that from himself as well, but again to no avail. "What is this?!" he shouted once more between coughs. Terriermon just grinned and kicked Impmon's leg out from under him, causing him to fall on his ass with a loud "thump".
     "Simple," Terriermon said. "Henry said I need to wear a diaper all the time so that I don't go on his floor anymore. And what better way to keep me from going than to keep the real culprit close to me at all times?" Impmon gasped, but it was too late; the transformation had already begun.

     Terriermon just stood by and watched gleefully as all the colors in Impmon's body began to simply fade away, leaving him nothing more than a pale, slightly off-white color. Impmon looked at himself and gasped, but would have more reason to be in shock as he saw his skin on his front side where Terriermon sprinkled him with the powder begin to change from being shiny and smooth to become almost perforated-looking, realizing it was very cloth-like in appearance and feel. If he could see his back, it remained more or less the same, but became more plastic-like in appearance and feel. Impmon felt his insides begin to feel queasy as they rearranged and began to transform as well, turning into a cloth-like material like his front -- spongy and absorbent. Now that his physical appearance was satisfactory, his form began to change to fit as well. Impmon began to wobble, falling backwards to the floor as his body began to grow thinner and almost flat if you were to look at him from the side. The joints and muscles in his body began to transform into the cloth-like material as well, leaving Impmon laying on the floor, almost completely flat but still soft and bulgy, and unable to move. His legs began to fuse together from the crotch to the knees, and the remaining parts of his legs that were left curved upwards (what looked to be quite uncomfortable for Impmon from Terriermon's point of view), his feet attaching in a strange way to his hips, forming the bottom half of the diaper where the legs go through from what used to be Impmon's waist down. Impmon's torso became shorter and wider, his arms forming a large circle and becoming the waistband of the diaper. His neck began to shrink into his torso, his head following suit as his face, twisted in a strange mix of confusion and terror, seemed to almost melt to approximately where the seat of the diaper's wearer would go. The remainder of Impmon's body began to finish the transformation, filling out to form a quite recognizable diaper shape; the soft, absorbent fabric on the inside, the plastic on the outside. A small, printed babyish Impmon face appeared on the seat of the diaper's outside, almost like a logo. Terriermon quickly picked up Impmon, slipping him on as he was supposed to be worn. Impmon's body began to finish up, shrinking and minor adjustments forming until the transformation stopped, leaving him what seemed to be nothing more than an ordinary diaper on Terriermon.

     Terriermon grinned, happy with his new diaper. Impmon, still completely aware of everything around him, began shouting complaints, but not only was his voice barely audible, being pressed up against Terriermon's butt made it completely un-understandable as well. Terriermon just laughed.
     "Looks like Henry won't have to worry about any more digi-poop on the floor since I'm taking care of the real shit now. But we can't disappoint Henry, now can we, Impmon?" Terriermon squatted down, straining as a bulge began to form in the rear of his diaper as he began to fill it with shit. Impmon's face was inside the diaper at ground zero for the incoming poop, and it twisted into a face of pure disgust as Terriermon's poop began to press up against his face, forcing the disgusting smell into his nostrils and the taste into his mouth. He didn't have to breathe, but the smell permeated his nose, and there was no escaping it. If he could have, he would have thrown up. But Terriermon just smiled happily, standing back up and picking up his original diaper off the floor, tossing it in the garbage. He wondered how long he could wear his new diaper before it would have to be thrown out from being too dirty, but he knew he would enjoy every moment of Impmon's suffering...
