“EHHH?!”
Iori popped his head around the corner, finding Rikai stood in front of the toilet door, frozen in shock.
“What’s the matter, Rikai-kun?” He asked as he approached the panicked man.
“The toilet!” Rikai yelled at Iori, “The toilet is broken !!”
Iori poked his head into the room, noticing a puddle of toilet water forming around the toilet bowl. “Oh dear,” he frowned, “it seems that it is…”
“Aghh, this is bad!!” Rikai pulled at his hair, “All the other toilets in this house are broken too! I’d thought this was the only working one in the household, but apparently not! Goodness, now we’ll need to call the plumber for multiple different problems...”
Iori stood up straight, puffing out his chest. “Don’t worry, Rikai-kun!” He saluted, “I shall solve this problem for you!”
“Don’t be silly, Iori-san,” Rikai sighed, “I doubt you know how to fix a toilet, let alone all the toilets in the house. I can simply call the-- What on earth are you doing?!”
Rikai looked down and met Iori’s gaze, who was kneeling before him so that his face was directly in front of Rikai’s crotch, holding his mouth open with a grin. “I shall be the household’s temporary toilet!” He responded, “Rikai-kun needed to pee, right?”
Rikai took a few steps back, pressing himself against the wall. “I’m not going to urinate in your mouth!” He scolded, “That’s not healthy, Iori-san!”
Iori crawled closer to Rikai, his cheerful expression turning to a more stern one. “Please use this slave’s mouth, Rikai-kun!” He raised his voice.
“You’re insane!” Rikai spat, running away down the corridor, “I don’t need to use the toilet! I’m fine! I’m not going to urinate until these toilets are fixed!”
Iori chased him down the corridor as he called, “I’m a toilet, Rikai-kun~ Please use my mouth as you wish~”
Rikai made a beeline for his bedroom, locking the door behind him just as Iori crashed into it, banging on it repeatedly. “Rikai-kun~!!” His muffled voice called, “You can pee in my mouth, Rikai-kun!!!”
Rikai ran to his desk, taking a seat as he grabbed his phone. He dialed the plumber hurriedly, bouncing his legs from the pressure building in his bladder as he waited for the call to be picked up.
Beeeep. Beeeep.
He dialed the number again.
Beeeep. Beeeep.
He groaned painfully, planting his face into his desk. Wonderful, he thought. No plumber, no toilets, the only option was to pee in his housemate’s mouth. Which he was not about to do anytime soon, he absolutely refused. Not just for his own dignity, but for Iori’s health as well. The only option for now, perhaps, was to hold it for as long as he could.
Two hours passed. Rikai wrapped a hand around his bladder, using the other hand to check the time on his phone. 20 minutes had passed. He grumbled quietly, he wasn’t sure how much longer he could hold it. He stood up and took some slow steps to the door, using all his might to keep his bladder together with every step. Iori had left to tend to something in the kitchen, as he could hear from the distant humming.
Rikai creeped through the corridors, looking around for something he could use. A plant pot? No, the plant would surely die. A bottle? No, it seems that Iori had thrown out any unused ones. The yard? Of course not, that would be public indecency. As he ran out of options, his bladder also ran out of space.
Pssshhh.
Rikai grabbed his crotch, but it was wet. He let go with a cry, wiping his hands on the sides of his pants as he watched a pale yellow spot form on the front of his pants. It grew in size, spreading through his underwear and staining his perfectly white pants. He squeezed his thighs together, desperately wishing the stream would stop. But it kept going, it kept leaking throughout the rest of his pants, trickling down his pant legs and spilling onto the floor in a growing puddle.
“Eh? Rikai-kun?” Iori popped his head around the corner, jumping in shock at the sight before him.
“D-don’t look at me,” Rikai stammered as he hid his blushing face, “I’ll clean it up, I’m so, so sorry…”
Iori ran over without hesitation. “Don’t say such a thing, Rikai-kun!”
“No, please don’t look at me, I-I’ll--”
Rikai paused as Iori dropped to his knees, bending down to lick at the puddle on the hardwood floor. “Don’t do that, for crying out loud!!” Rikai yelled, “I told you I’ll clean it myself! And use a mop or something, not your tongue!!”
“But I’m a toilet, no?” Iori hummed as he continued to lap at Rikai’s piss, “This is my duty!”
“It’s unhygienic and unhealthy, Iori-san!!” Rikai scolded as he regained control of his bladder, taking a step back, “Goodness, you could have just helped by finding some sort of bottle or vase for me instead…”
“You don’t wanna pee in my mouth?” Iori asked, looking back up at Rikai.
“Not a chance.” Rikai shook his head.
“How about in a diaper?”
Rikai glared at Iori in silence, processing what he just said.
“...A diaper?”
“Yeah, just like me,” Iori nodded as he undid his belt and lowered the waistband of his pants, revealing the plasticky material underneath, “You don’t need to pee in my mouth, but you can pee in this!”
“You’re joking,” Rikai scoffed, “I would rather die than wear a diaper. I’m not a pants-wetting toddler.”
“Well,” Iori cocked his head, “you did wet your pants. Besides, lots of adults use diapers too! For incontinence, for those who’re bedridden, for the elderly, it’s really not a big deal!”
Rikai frowned. Iori was right, he was making this a bigger issue than it really is. “So why do you wear them?” He raised an eyebrow.
“Oh, since I’m the toilet of the house, it would be difficult for me to drink my own pee!” Iori smiled, “So I use a diaper to hold all of it then I throw it out! It’s also helpful when I’m doing other stuff like cooking and laundry, so I don’t need to take a break!”
Such an Iori answer, Rikai thought to himself. He would argue that agreeing to this would rid him of his dignity, but frankly, it was a much better option compared to peeing in his pants or Iori’s mouth.
“C-can…” Rikai stuttered, “C-can you… sh-sh-show me… how to use one…?”
“Of course~!” Iori nodded, “You could take a shower first so you’re all clean, and I’ll get back to you once I’m done cleaning up~”
Rikai scowled as Iori returned to licking his piss off of the floor. What a character, he thought as he turned to enter the bathroom.
“Rikai-kun~ Are you all done?” Iori knocked on the bathroom door.
Rikai creaked the door open, peering out cautiously. Iori was stood there, holding a clean diaper in his hands, and wearing a bright, beaming smile on his face. “Let’s go to your room, Rikai-kun,” Iori sang.
Iori followed a fully dressed Rikai to his bedroom, laying the diaper out on the bed. “Just lie down here!” He hummed, patting the open diaper invitingly, “And take your pants off! It’s supposed to go under it, silly!”
Rikai tsked and peeled off his pants shyly, using one hand to cover his crotch as the other pulled the pants down to his ankles. He kicked them off, approaching the bed to lay down where Iori had gestured.
“No need to cover that, Rikai-kun!” Iori chuckled as he removed Rikai’s hands, revealing his limp dick underneath. It was small, probably small enough to be considered a micropenis. But Iori didn’t care much, he didn’t expect much either. He folded the front of the diaper over his crotch, wrapping it up with tapes so it was secured snugly to Rikai’s waist.
“There you go~” Iori sang gleefully as he patted Rikai’s diaper affirmingly. Rikai’s cheeks were a bright red, he couldn’t believe he stooped down to such a level. It was only temporary, he reminded himself, the toilet will be fixed soon.
“Alright…” he sat up, “now get out of here. And don’t tell anyone about this.”
“Yes sir!” Iori saluted as he skipped out of Rikai’s room. Rikai sighed as he got up, pulling his pants back on. He wasn’t sure how to feel about it, or rather, he was avoiding feeling anything about it. He wanted to hate it, but what Iori mentioned was a reasonable argument. It’s not like it was only for children, and besides, it was only temporary. It also felt… comfortable. It was soft and hugged his hips nicely, almost as if it was encouraging him to use it.
He placed a hand over the front of it, feeling the shape of his cock underneath. It was barely there, considering its size, but he could feel just the slightest bit of pressure on his dick. It must have pushed him over the edge, as he began to feel a warmth in the front of the diaper.
He held his breath as the spurt of piss slowly turned into a stream. The warmth spread through the diaper, covering the rest of his crotch in the sinful, wet feeling. It felt a little shameful, peeing in a diaper like this. But the feeling of it was a little addicting, he couldn’t help but grind his hips into the warmth a little. Goodness, he felt more perverted than Amahiko, but it felt like such a soft and warm hug around his waist, he couldn’t help it.
He massaged his dick lightly through the diaper with one hand, but he could barely feel it. It had expanded from absorbing the piss, enough for his dick to be completely hidden away. He couldn’t even feel the pressure from his hand on his dick, it was just barely there. He breathed slowly and deeply, relishing the massages that felt light and subtle through the thick diaper, a small tent gradually growing on the front of it.
He opened his lips and sighed softly, massaging with more pressure. He could still barely feel anything, but it was less the actual feeling and more the idea of it. The idea of being so deprived of sex and stimulation that he could get hard even with the slightest feeling of anything on his dick, that he could get hard from doing such a disgusting, perverted act. He hated how good it made him feel, he hated that the great and wonderful Kusanagi Rikai had let go of all his pride and dignity to become a diaper-loving pervert, and he hated how much all those thoughts hardened his leaking dick.
But it wasn’t quite enough to push him over the edge. He bit his lip and thrusted his hips into his hand, desperate for any more stimulation, anything to get him to his high. But it just barely got there. He whined softly as he felt liquid spill from his cock, just for a second. He never had such a weak orgasm before, he was left from it still feeling so needy. He sighed hopelessly, panting softly as he finally zipped his pants up, dusting his hands off on his hips before getting back to his work.
He didn’t want to believe he did all that. Not just because of how ashamed and gross he felt, but also because of how heavily he’d diverted from his own principles. Being gross and perverted was one thing, Kusanagi Rikai being gross and perverted was a whole other thing entirely. He shook his head as he sat down at his desk slowly, sinking into the thickness of the diaper like a cushion.
Frankly, if he was being completely honest with himself, he wouldn’t mind this kind of change.
