[Kikuichi Monji] B Guruupu Komisshon Kanryou

Schoolgirl Saya-chan pleads with her classmate Yuko during class, her bubbling stomach threatening disaster until the teacher finally grants a bathroom break. The girls slip away together, and the bespectacled troublemaker can't resist dropping a loud one in the stall, much to Saya's mortified embarrassment. Yuko doubles over in agony as her system gives out entirely, painting the tile floor and leaving Saya speechless at the stench of her best friend's accident.
