[Kikuichi Monji] Kaigai Kara No Komisshon

After school, a timid schoolgirl nervously lures her classmate Yu-kun into a dark, empty bathroom with a nervous "please," inviting him to help her with an embarrassing, smelly secret she cannot contain. She shyly hikes up her pleated skirt over her thong-clad, bubble butt and bends over, warning him not to look or listen as she unleashes her potent relief, leaving the overwhelmed boy red-faced and gasping at the reeking aftermath.
