All I could find was a post on Gelbooru:

Unfortunately there's identifying information. Here's a translation of the text, if you're interested.
Original text:
まず出てきたのは、うんと腹に響く低音の放屁だった。
浣腸直後なのに放屁。注入した水分が固形便に吸収された証拠。
Google's translation:
The first came out, it was sounding bass belly flatus account.
But that after flatus enema. Evidence of moisture absorbed by the injected solid stool.
My attempt at a cleanup:
It started coming out, with a deep blast of flatulence. Then the enema followed. Moisture was apparently soaked into the solid fecal matter.
What happens after the text?
Odds there might not be much to be seen. It seems few of these eroge/visual novel style games show any shit, which is a shame, seeing as how there's that Kusoge series that's always talked about on gurochan, and that seems more than willing to show shit and piss.
What's the game called?
