Before I post the Grayble finale, I think I might write a Su omo. This takes place when Su is captured by Nikaidou. 243 words
Su never had the strongest of bladders. And while Ran, and sometimes Miki, are okay with relieving themselves outside, Su wouldn't. But right now, she was stuck in a cage with no access to a toilet whatsoever. "Sensei, may I use the bathroom?" Su asked. "No, you're just going to escape." Nikaidou said. "But I really have to go-desu!" Su cried. "Is it number one?" Nikaidou asked. Su nodded. "Then I'm gonna give you a rag" Nikaidou said, "You can relieve yourself on that." Su blushed. "N-No! I don't want to! I need a toilet-desu!" Su cried. Nikaidou sighed. "Fine. I'll let you use my bathroom" Nikaidou said. Nikaidou took the cage and brought it to this bathroom. He locked the door, and opened the cage. "Uh... sensei..." Su said, "Can you give me some privacy" Nikaidou turned around. Su didn't like the fact that he was still in the room, but it didn't matter. Su pulled down her panties and squatted over the toilet, since she was too small to sit on it. She relaxed and started relieving herself. "Ah... Desu..." After another minute or two, Su's stream died down. "Are you done?" Nikaidou asked. "Yep!" said Su, as she got some toilet paper and wiped herself. She pulled her panties back up, and flushed the toilet. After washing her hands, she went back into the cage. She still was being held hostage, but at least she got the relief she needed.
