The scene with Reiko waking up and passing gas is a good way to begin. The character gets a nice introduction and explanation. There is buildup toward the climax from the very beginning. The climax is amazing, of course. The half-deliberate accident is very detailed, and you describe it cleverly. I like the irony of the line, "Just need to get up, and squat!"
A couple proofreading issues. You say "Reiko was beside herself" twice. I think "a bubbling warms" is supposed to be "a bubbling warmth."
I like this character, but I'm not sure what more you should do with her. It would be cool to see her almost get caught, either in a new chapter or an extended version of this chapter. For example, it would be cool if the door was opening just as she threw her panties away, giving her an adrenaline rush as she buried the evidence at the last possible moment.
I'm a big fan of the new chapter! This one was always a favorite of mine, and the origin story is definitely welcomed. I'm always interested as to why a Nyou-Character does what she does in the story, and this origin really patches it up. Nice work.
As far as an ending goes, I think it was a nice touch. There was a little whimsy in it (or that's what I felt when I read it.) and gives the story a little bit of playfulness. Overall, very nice work :D
Author's Response: Thanks. Glad you enjoyed it.
I approve of the masturbation scene at the end. This is a story about a chick who gets hot from pooping herself. What do people do when they get horny ... they take care of it :).
Good work.
Author's Response: Exactly. Anyone whose read an Arthur Saxon story can attest to this. Glad you liked it, I was starting to wonder if I wouldn't get many reviews for this, what with the fact it's gotten a ton of reads already.
Besides my dislike for masturbation, and the fact that this is more a scene than a story, my criticisms are minor. The part with the meeting seems out-of-place. I think you should have either removed it or expanded it into something more substantial. There was also one sentence that bothered me: "Ever since she was fourteen, Reiko enjoyed defecating, an act which she took great pleasure in." That seems redundant.
I think you do a fine job describing Reiko and her intentional "accident," and I would enjoy reading about her again, provided her secret pleasure doesn't reach such a height.

Oh pish-posh, what's the harm in seeing a masturbation scene? It's a natural thing.
While I admit the story is short, I hardly think it's a scene. A 'scene' is something that occurs in one place and normally like an excerpt from a full story. The meeting could have been a bit longer, but I didn't want to take too much focus off of what she was planning to do. Besides, it was necessary to establish she's a hard worker who does her job, not just stare at reports then go home all of a sudden.
