[SilentWolf] School Girl Memories 3.0 [Pixiv]

An anxious schoolgirl class representative leads her group on a hike, desperately trying to conceal her urgent need to poop while keeping the group together. As the trek progresses, her friends tease and push her, heightening the comedic tension until she can no longer hold it and suffers a messy accident in the wild. The story blends everyday school life with exaggerated bodily urgency for a humorous, scat‑focused doujinshi.
