Kris had convinced him that this new armour set would be perfect for him, especially since he was still stuck in diapers after their last visit to the new dark world. The set was fairly simple, mittens, booties, and a special kind of cover for his diaper.
Ralsei almost immediately regret putting it on. Once Kris helped him put on the final piece Ralsei felt his magic disappear.
"Uh, Kris? This set has a magic suppressing de-buff, maybe I shouldn't be using it..." He said meekly.
Kris grinned, giving the goat a pat on his now rubbery padded rear. Ralsei squirmed, Kris had been teasing him more and more about needing his diapers ever since their last adventure... Without even realizing it he felt his diaper suddenly growing warm. He gasped, paws shooting to his crotch to hide his clearly visible accident.
"C-can I at least have a longer shirt? Please?" He pleaded. Kris shook his head, grinning ear to ear now. Before he could get in another word Ralsei felt something else happening. His cover felt strangely snug, despite being so loose when he put it on. Surely he hadn't gone that much had he? Looking down the prince let out a gasp, his cover was slowly growing larger, inflating between his legs.
"K-Kris, w-what's going on?"
Kris let out a snicker and patted his friend's butt again. Ralsei tried to step away, prepared to beg his friend for help when he felt something else happening, an all too familiar, ominous gurgling in his stomach. His eyes widened and he began to panic, tugging helplessly at the still slowly expanding cover with his useless paws.
"Kris help! I need to go! I can make it if you just help me get this off right now!" He pleaded, his puffy paws sliding uselessly over the cover. Kris couldn't contain himself, his grin turning slightly sadistic as he shook his head.
"K-kris?" Ralsei whimpered as it dawned on him, Kris wasn't going to help him, in fact he almost seemed to want this to happen... He opened his mouth to plead again, but it was too late. With an audible grunting he felt his body squat and begin to push, warm mush pushing it's way into his waiting diaper. As it did he felt the cover suddenly begin to expand even faster, almost impossibly fast. Within a few seconds of his accident starting he felt his cover pushing agaisnt the ground and begin to lift him. Rendered helpless, in multiple ways now, the poor goat could only whine as he finished his accident, the still expanding cover pushing the mushy mass against his bottom and spreading it throughout his diaper.
After a few minutes both his accident, and the expanding slowed, then stopped. By then Ralsei had tears streaming down his face, why had his friend done this? Why did he want him to poop his pants like that? More importantly, why did it feel good suddenly?
Still sniffling the poor goat looked at his friend, "Kriiiiiiiiis, whyyyyyyy?"
