Students have a very tight lunch schedule. This work focuses on the excretion situation of girls during lunch break. Some girls rush to the toilet after lunch because they need to defecate, and some girls hold their poop in while having girl talk, and then rush to the toilet at the last minute of lunch break and release a large amount of poop while panting. Many girls were seen with poop right up to their anus during lunch break. They don’t want anyone to know that they are pooping in the school toilet that their classmates use. When they are called out to from the hallway, they pretend not to know, but they return to the classroom, very worried about the smell of their poop.

突然の尿意に苛まれ、きっと出せるだろうとトイレに向かうも、便座がない…。パンツを脱いで座った途端、お尻に冷たい感覚が駆け巡り、到着した安堵感は一転パニックに、準備が整うまで待ち構えていた尿意に頭が真っ白に。便器の縁に紙を敷いて何とか回避しようとするが効果はなく、ただ立ったまま排尿する。慣れない体勢の羞恥心と解放感がせめぎ合い、おしっこは便器のタンクに飛び散る。真顔でウロウロしていたあの娘は、立ち小便をしてしまった。
