I was walking down a large corridor hallway, surrounded by armed guards, four of them, as they had be walking with a metal collar, the same one that they used for SCP 049, The Plague Doctor. However, I had no intention on causing violence or anything, guessing this was a precautionary to make themselves feel safe. No sooner than a minute, we came to a complete stop, as one of the guards opened the door for me. Some peace mission. They some unhooked the collar from me as I waddled into the room, as my diaper was somewhat wet from the trip to this, 'peaceful deal seal.' Whatever that means, but the scientist said that it would be the trusting bond between the humans and the SCP. I rolled my eye when he called me an SCP, that was pretty silly, though they did take DNA samples from me and may have seem the human part of my DNA, but no matter, I'm doing this for peace. No sooner as I was inside a large emptied room, the doors behind me closed shut, as they were like a safety row so if one door breaks, the others will hold. And no sooner did I said the strange nonbranded diaper with a Japanese symbol meaning 'swell' or 'too swell' on the floor.
"Alright then 'Khad,' I hope you are comfortable with changing yourself with a viewing standby." The scientist said from a very high window view.
"My mom sometimes changes me in public, and my dad changed me during war, this is nothing different." Khad said, as he was undoing his diaper already.
"Quick to the point I see, guessing you're a bit excited for it."
"I don't even know what this SCP does, but I heard it was labeled safe, so I'm willingly to try." Khad soon had his lower half naked, as he wrapped up the wet diaper and put it on the side. Now he was unfolding SCP-552-R, and started to put it on him.
"I'll reassure you, that this will have no problems with our peace treaty, not to mention that you have somewhat interests with inflation or filling." He said, making Khad blush a bit.
""Next time I'll keep my personal liking's to myself." Soon Khad finished diapering himself, as SCP-552-R was on him. "So now what?" He asked looking up at the window.
"Now, we wait and see." The scientist said. As just then, Khad heard his stomach gurgling, or at least he thought it was his stomach, as he then felt the padding around his waist started swelling up, as it felt very thick and soft like. Khad couldn't help but started purring like crazy, as he couldn't believe that something like this was happening. Just then, SCP-552-R's waistband had changed into blue, as it was yellow before.
"huh? Guess this diaper knows what's it's doing." Khad said, purring mindlessly over this.
"Indeed it has, so do you think this is a great deal to seal the treaty off? I'm pretty sure you could make something off of this for your fellow species." The scientist said, as Khad's ear's perked up.
"Oh... heck yeah..." Khad murred as the padding was now touching the ground, lifting Khad up a bit before and intense gurgle noise was made in the diaper, as a big one was gonna happen.

So this art was made by  imjusthereforpics as this was a request I wanted from him, when I saw his SCP diaper, but he was so nice to have me post this on my galley, and I want everyone to know how nice this guy is. So check out his art, and give a big favorite to his gallery and stuff.
